Answer:66.7%
Step-by-step explanation:
Anyone? Please I need help!!
Answer:
the correct choice is marked
Step-by-step explanation:
Let x represent the smaller number. Then the larger number is 8x, and the difference is ...
8x -x = 280
7x = 280 . . . . . simplify
x = 40 . . . . . . divide by 7
The larger number is 8x = 8(40) = 320.
_____
Additional comment
Effectively, we have solved for the multiplier (40) that gives the ratio with 320 on top and a difference between top and bottom of 280:
[tex]\dfrac{8}{1}=\dfrac{8\cdot40}{1\cdot40}=\dfrac{320}{40}[/tex]
If 1kg of beef cost $230, what is the cost of 0.5kg of beef?
The cost of 0. 5 kg of beef, considering the cost of 1 kg of beef, can be found to be $ 115
How to find the cost of beef ?The cost of beef in this instance is directly proportional to the quantity of beef that is being bought by the customer. What this means is that if more kilograms of beef is bought, then the person would pay more for the beef and if less kilograms are bought, less would be paid for the beef.
This is why 1 kg of beef goes for $ 230. And it is why 0. 5 kg of beef would be sold for less.
To find the cost of 0 . 5 kg of beef, the formula is:
= Cost of 1 kg of beef x Number of kilograms of beef purchased
= 230 x 0. 5
= $ 115

The perimeter of the rectangular park is P = 984 m
What is the Perimeter of a Rectangle?The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.
Perimeter P of rectangle = 2 ( Length + Width )
Given data ,
Let the scale of the rectangular park be 1 cm = 60m
Now , the Perimeter P of rectangle = 2 ( Length + Width )
The length of the rectangular park L = 4.5 cm = 4.5 x ( 60 )
The length of the rectangular park L = 270 m
And ,
The width of the rectangular park W = 3.7 cm = 3.7 x ( 60 )
The width of the rectangular park W = 222 m
Now , the perimeter of rectangular park = 2 ( 270 + 222 )
The perimeter of rectangular park P = 984 m
Hence , the perimeter of the rectangular park is 984 m

please help with this question algebra 1
Answer:
Examples for the problem would be:
1) Robert started to run out of his house as fast as he can
2) But he slowed down when he met up with his friends
3) They then stopped at a park along the way
4) After stopping at the park, they ran the rest of the way to school hoping they wouldn't be late.
or
1) Robert met with his friends right outside his house and raced them to the next block
2) After Robert won, they all walked normally to the park
3) They then stopped at the park for a quick break
4) After realizing class was gonna start in a few minutes, they ran as fast as they could to school
Step-by-step explanation:
For the first part, you want Robert to be running at a normal running speed, such as him racing his friends or just running.
For the second part you want him to be walking at a slower pace.
For the third part you want them to not be moving
For the fourth part, you'll explain how/why they're moving so fast since the graph shows that he ran fastest at this time.

A pilot and co-pilot are performing a test run in a new airplane. The pilot is required to take off and fly in a straight path at an angle of elevation that is between 33° and 35° until the plane reaches an altitude of 10,000 feet. When the plane reaches 10,000 feet, the co-pilot will take over. Round each distance to the nearest tenth.
Using the slope concept, it is found that:
The minimum horizontal distance is of 14,281.5 feet.The maximum horizontal distance is of 15,398.6 feet.What is a slope?The slope is given by the vertical change divided by the horizontal change.It's also the tangent of the angle of depression.In this problem, the vertical change is the altitude of 10,000 feet.
The minimum horizontal distance is with an angle of 35º, hence:
[tex]\tan{35^{\circ}} = \frac{10000}{d}[/tex]
[tex]d = \frac{10000}{\tan{35^{\circ}}}[/tex]
[tex]d = 14281.5[/tex]
The maximum horizontal distance is with an angle of 33º, hence:
[tex]\tan{33^{\circ}} = \frac{10000}{d}[/tex]
[tex]d = \frac{10000}{\tan{33^{\circ}}}[/tex]
[tex]d = 15398.6[/tex]

Seventy- five percent, or 15 of the students in Emily’s home room class are going on a field trip. Two thirds, or 12 of the students in Santiago’s home room class are going on a field trip. Which class has more students? Justify your answer.
Answer:
Emily has 20 students and Santiago has 18 students in home rooms
Step-by-step explanation:
to figure out the number in Emily's class we need to answer this question - '15 is 75% of what number'?
we can use:
is/of = %/100
is = 15
of = 'n'
75% = 75/100 or 3/4
15/n = 3/4
cross-multiply to get:
3n = 60
n = 20
So there are 20 students in Emily's home room
Now we find the number of students in Santiago's home room:
the question is - '12 is 2/3 of what number'?
we can write this equation:
12 = 2/3n
multiply each side by 3/2 to get:
36/2 = n
18 = n
18 students in Santiago's home room

[tex]-6=\frac{n}{3} -8 \\2 = \frac{n}{3} \\n = 6[/tex]
Inverses are your friends, for example to get [tex]n - 3 = 0[/tex] where n is on one side, do the inverse of subtraction ( addition) so you get [tex]n - 3 + 3 = 3 \\\\n = 3[/tex]
[tex]-7 = \frac{n}{4} - 3 \\-4 = \frac{n}{4}\\n = -16[/tex]
[tex]-13 = 5y + 7 \\-6 = 5y \\[/tex]
On "y" there is a coefficient of 5, aka [tex]5*y[/tex], the inverse of multiplication is division
[tex]\frac{-6}{5} = y[/tex]
[tex]-6 + \frac{x}{2} = -3\\ \frac{x}{2} = 3 \\x = 6[/tex]
You finish the rest, but you gotta remember this, isolate the variable (x, y, z, whatever) by doing inverses
inverses
addition - subtraction
multiplication - division

Jia is skipping a rock across a pond. The sequence {4.2, 3.57, 3.0345, 2.5793, …} describes the height of the rock on each successive skip. Which explicit formula describes this geometric sequence?
Answer:
[tex]u_n=4.2(0.85)^{n-1}[/tex]
Step-by-step explanation:
[tex]u_1=4.2\\u_2=3.57\\u_3=3.0345\\u_4=2.5793[/tex]
Geometric formula sequence: [tex]u_n=ar^{(n-1)}[/tex]
(where [tex]a[/tex] is the first term of the sequence and [tex]r[/tex] is the common ratio)
To find the common ratio, divide one of the terms by the previous term:
[tex]r=\frac{u_2}{u_1} =\frac{3.57}{4.2} =0.85[/tex]

Question 1 options:
Find the factors of b that add up to c.
Find the factors of c that add up to b.
Find the factors of c that multiply to b.
Find the factors of b that multiply to c.
Answer:
Find the factors of c that add up to b.
Step-by-step explanation:
For example, if you were factoring
x^2 + 12x + 35
a=1
b=12
c=35
In order to factor, we're looking for what multiplies to 35, and adds up to 12. What multiplies to 35 are the factors of 35. In this case its 5 and 7.
5 × 7 = 35
5 + 7 = 12
So you could factor
x^2 + 12x + 35
= (x + 5)(x + 7)
Leading coefficient=a=1
So
the equation becomes
x^2+bx+cNow find the factors of c that can add up to bUsually we find factors of ac but as a is 1 so it yields c only

[tex]1750(1-0.33)^{\frac{5}{12} }[/tex] is the expression that best models the situation.
$[tex]1472[/tex] will be value of computer after 5 months.
What is depreciation rate?
The depreciation rate is the percentage rate at which asset is depreciated across the estimated productive life of the asset. It may also be defined as the percentage of a long term investment done in an asset by a company which company claims as tax-deductible expense across the useful life of the asset.
According to question, Steve buys a computer for $[tex]1750[/tex]
This value has a depreciation rate of [tex]33[/tex]% annually.
The expression best models this situation is
[tex]1750(1-0.33)^{\frac{5}{12} }[/tex]
[tex]=1750[/tex]×[tex]0.66^{0.416}[/tex]
[tex]=1750[/tex]×[tex]0.841[/tex]
[tex]=1472[/tex]
Hence, we can conclude that [tex]1750(1-0.33)^{\frac{5}{12} }[/tex] is the expression that best models the situation and $[tex]1472[/tex] will be value of computer after 5 months.
