1>) Alexa's 4th grade class has a spelling list organized by subject. The spelling list includes
170 words about history, 75 words about science, 60 words about math, and 55 words about
geography. Each week, Alexa's teacher tests her on 15 words from the list. Alexa's class has
already had 7 weeks of spelling tests. How many more words will Alexa be tested on before
the end of the year?
Answer:
Solution:
Total words are 170 + 75+60+55=360.
Each week, Sofia is test with 15 words from the list.
Total number of weeks it will take to finish the test is 24.
Average number of weeks in a year is 25 approximately.
Seven weeks are already over, that means 15×7=105 words are covered from the list. Conclusion:
Remaining words are 360—105=255.
These words can be covered in a group of 15 in a week, so 25515=17 are the number of weeks.
Therefore, the number of words that Sofia will be tested on before the end of the year is 255.
Step-by-step explanation:
Answer:
170+75+60+55=360
15x7=105
360-105= 255
Alexa has 255 more words until the end of the year.

By selling a chair for $372, Daisy loses 7%. At what price must she sell it to gain 10%.
Answer: $440
Step-by-step explanation:
Given selling price = $ 372
Loss % = 7%
We know, cost price = selling price × 100/100 - loss%
Therefore, cost price = 372 × 100/100 - 7
= 372 × 100/93
= $400
Now cost price = $400
Gain% = 10%
Therefore, selling price = (100 + gain%)cost price/100
= (100 + 10)400/100
= 110 × 4
= $440
One factor of f (x ) = 5 x cubed 5 x squared minus 170 x 280 is (x 7). What are all the roots of the function? Use the Remainder Theorem. X = –4, x = –2, or x = 7 x = –7, x = 2, or x = 4 x = –7, x = 5, or x = 280 x = –280, x = –5, or x = 7.
To solve the problem we must know about the Remainder Theorem.
What is the Remainder theorem?According to the remainder theorem, when a polynomial P(x) is divided by (x-t) then the remainder of the division is equal to P(t). If P(t)=0, then the (x-t) is the factor of the polynomial.
The roots of the function are -7, 2, and 4.
Given to us
One factor of f (x) = [tex]5x^3+5x^2-170x+280[/tex] is (x +7).What is the quotient of the function?We know (x+7) is the factor of the function, f(x) = [tex]5x^3+5x^2-170x+280[/tex],
therefore,
[tex]f(x) =5x^3+5x^2-170x+280 = [(x+7) \times quotient] + Remainder[/tex]
As (x-2) is the factor of the function, therefore, the remainder will be zero for the equation,
[tex]\rm quotient=\dfrac{5x^3+5x^2-170x+280}{(x+7)}[/tex]
[tex]\rm quotient=5x^2-30x+40[/tex]
What are the factors of the function?Solving the quadratic equation,
[tex]5x^2-30x+40\\\text{Dividing the equation by 5}\\\\=x^2-6x+8\\=(x-2)(x-4)[/tex]
Hence, the roots of the function are -7, 2, and 4.

Megan buys 2 new shirts for $16 each, crocs for $34, and a hat for $13. She bought the new clothes with a discount code of 15% off. How much did everything cost Lilah if there was also a 5% sales tax? (Round to the nearest hundredth)
Answer:
2 shirts - 16$ each
i.e. 32$
1 crocs pair - 34$
A hat - 13$
so the total she spent was,
16+16+34+13 = 79$
Now, if she is using 15% off in the total amount that will cost her => $11.85 !
since she is paying 5% sales tax so the final she paid is:

A company rents out 18 food booths and 23 game booths at the county fair. The fee for a food booth is $175 plus $8 per day. The fee for a game booth is $50 plus $7 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
Answer:
Step-by-step explanation:
For the food booths, we can create an equation based on the y = mx + b equation. Since they are charging 8 dollars per day and they last for d days, then the slope is 8 or the rate is 8d. Since they also charge us 175 dollars which is a one time fee, it is the y-intercept. So the equation is
y = 8d + 175.
Since there are 18 food booths, then we can multiply the equation by 18.
y = 18(8d + 175)
y = 144d + 3150
For the game booth, we do the same thing. Since they charge us 7 dollars per day and the fair lasts for d days, then the rate is 7d. Since they also charge us 50 dollars as a one time fee, then it is the y-intercept. The equation for the game booth is:
y = 7d + 50
Since there are 23 game booths, multiply the equation by 23.
y = 23(7d + 50)
y = 161d + 1150
Now add them up to know how much they are being paid.
y = 305d + 4300

1) You want to put up a basketball hoop in your backyard, Regulation height for the basketball hoop is 10 feet
or 120 inches. After a couple of attempts at guessing the correct height and checking, you decide to use
shadows to estimate the height. You are 68 inches tall, and your shadow is 62 inches long. You are
standing 41 inches from the pole and the tip of your shadow coincides with the tip of the basketball hoop's
shadow as shown in the diagram below. To the nearest foot, what is the height of the basketball hoop?
SRT.1.2 (6 points)
By using the known relations for similar triangles, we will see that the height of the basketball hoop is H = 113 ft.
How to find the height of the basketball hoop?
In this situation, you and your shadow make a similar triangle to the one that makes the basketball hoop and its shadow.
This would mean that the quotients between the sides must be the same, so:
The quotient between your height and your shadow's length must be the same as the quotient between the hoop's height and its shadow's length.
Your height is 68 inYour shadow is 62 in long.You are at 41 in from the pole, and your shadow coincides with the shadow of the pole, so the length of the pole's shadow is:
41in + 62in = 103 in
And we define H as the height of the basketball hoop.
So we have that:
H/103in = 68in/62in
H = (68in/62in)*103in = 112.97 in
Rounding to the nearest foot, the height is 113ft.

You can use the recursion xn=(xn-1+10/xn-1)/3
the process of iteration to estimate the value of
V10 without using a calculator. What is the value
of the 2nd iterate if x0 = 3.1? Carry out your
answers to the 5th decimal place.
Using the recursion equation, it is found that the value of the 2nd iterate is:
[tex]x_2 = 3.16228[/tex]
What is the recursive equation?The value of the nth iteration is given by:
[tex]x_n = \frac{x_{n-1} + \frac{10}{x_{n-1}}}{2}[/tex]
The initial estimate is:
[tex]x_0 = 3.1[/tex]
Hence, the 1st iterate is given by:
[tex]x_1 = \frac{x_0 + \frac{10}{x_0}}{2} = \frac{3.1 + \frac{10}{3.1}}{2} = 3.1629[/tex]
The 2nd iterate is:
[tex]x_2 = \frac{x_1 + \frac{10}{x_1}}{2} = \frac{3.1629 + \frac{10}{3.1629}}{2} = 3.16228[/tex]

A 12-V battery powers three lightbulbs in a series circuit. The voltage reading is 6 V across the first lightbulb and 3 V across the second lightbulb. What portion of the battery's energy transforms in the third lightbulb?
Please show how you got the answer!
Answer:
[tex]\displaystyle \frac{1}{4}[/tex].
Step-by-step explanation:
The voltage across the three bulbs would add up to [tex]12\; {\rm V}[/tex] since the three bulbs are connected in serial.
The voltage across the third bulb would thus be: [tex]12\; {\rm V} - 6\; {\rm V} - 3\; {\rm V} = 3\; {\rm V}[/tex].
Also because the three bulbs are connected in serial, the current going through each of them be the same as the size of the current of the whole circuit. Let [tex]I\; {\rm A}[/tex] be the size of that current.
The power supplied by the battery would be [tex]P = V \, I = 12\; {\rm V} \, (I\; {\rm A}) = (12\, I)\; {\rm W}[/tex].The power of the third bulb would be [tex]P = V\, I = 3\; {\rm V} \, (I\; {\rm A}) = (3\, I)\; {\rm W}[/tex].Thus, the portion of the power consumed by the third bulb would be [tex](3\, I) / (12\, I) = 1/4[/tex].

An isosceles triangle has two sides of equal length, a, and a base, b. The perimeter of the triangle is 15. 7 inches, so the equation to solve is 2a b = 15. 7. If we recall that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side, which lengths make sense for possible values of b? Select two options. –2 in. 0 in. 0. 5 in. 2 in. 7. 9 in.
The lengths that make the sense for the value of b are 0.5 inches and 2 inches.
GivenAn isosceles triangle has two sides of equal length, a, and a base, b.
The perimeter of the triangle is 15.7 inches, so the equation to solve is 2a + b = 15.7.
What is the triangle inequality theorem?If two sides of a triangle are unequal, the longer side has a greater angle opposite to it.
[tex]\rm a+a > b\\\\2a > b[/tex]
The equation of the perimeter of the triangle;
[tex]\rm 2a+b = 15.7\\\\2a = 15.7-b\\\\a = \dfrac{15.7-b}{2}[/tex]
1. Substitute b = 0.5 in the equation;
[tex]\rm a = \dfrac{15.7-b}{2}\\\\ a = \dfrac{15.7-0.5}{2} \\\\ a = \dfrac{15.2}{2}\\\\a = 7.6[/tex]
Then,
Verify the triangle inequality theorem;
0.5 + 7.6 > 7.6 is true
7.6 + 7.6 > 0.5 is true
2. Substitute b = 2 in the equation;
[tex]\rm a = \dfrac{15.7-b}{2}\\\\ a = \dfrac{15.7-02}{2} \\\\ a = \dfrac{13.7}{2}\\\\a = 6.85[/tex]
Then,
Verify the triangle inequality theorem;
0.5 + 76.85 > 6.85 is true
6.85 + 6.85 > 2 is true
Hence, the lengths that make the sense for the value of b are 0.5 inches and 2 inches.

my question is “explain how to use partial quotients to divide 235 by 5.”
Answer:
235 can be split into 200+30+5. Each of these can be divided by 5: 200/5+30/5+5/5=40+6+1=47 to give us the quotient.
Another way is to double 235=2*200+2*30+2*5=400+60+10=470 and divide the result by 10 by simply removing the zero to give the quotient 47. This works because dividing by 5 is the same as doubling and dividing by 10: 2/10=1/5.
nathan ordered one cheeseburger and one bag of chips for $3.75. jack ordered two cheeseburgers and three bags of chips for $8.25
Answer:
Cost of a bag of chips is $0.75
Cost of a cheeseburger is $3.
Step-by-step explanation:
[Step 1] Let the cost of a cheeseburger be x.
[Step 2] Let the cost of a bag of chips be y
[Step 3] As it is given that x + y = 3.75
[Step 4] It is also given that 2x + 3y = 8.25
[Step 5] Multiplying the equation in [Step 3] by 2 and we get 2x + 2y = 7.50
[Step 6] Subtracting the equation in [Step 5] from the equation in [Step 4] we get y = $0.75
[Step 7] Therefore the cost of a bag of chips is $0.75
[Step 8] Substituting the value of y found in [Step 7] into [Step 8] we get x = 3.
[Step 9] Therefore the cost of a cheeseburger is $3.
Check Answer:
Chip = 0.75
Cheeseburger = 3.00
Nathan Ordered one cheeseburger and one bag of chips for $3.75.
3.00 + 0.75 = $3.75
Hence, Chip = 0.75 and Cheeseburger = 3.00 is correct.
------------------------------------------------------------------------------------------------------
Chip = 0.75
Cheeseburger = 3.00
Jack Ordered two cheeseburger and three bags of chips for $8.25.
2 Cheeseburger = 3.00x2 = 6.00
3 bags of chips = 0.75x3= 2.25
6.00+2.25=$8.25
Hence, Chip = 0.75 and Cheeseburger = 3.00 is correct.

I need some pointer, 3 will do :)
Answer:
academics are more important than sport sports.
Step-by-step explanation:
studies are always more important than sports, because studies have more job opportunities than sports. If you are good at your school subjects than there will be many possibilities to get into a good collage and a good or decent paying job, but with sports on the other hand its much harder to get a scholarship and your preformance has to be perfect to almost perfect and quite frankly the average sports scholarships is less than $11,000 which if you look at it isnt that much. And you are more prone to getting injuries.
