Ricardo has $25 to spend on school supplies. He spends 56% of the money on a backpack and the rest on a large binder. How much money does he spend on the backpack? How much does he spend on the binder
Answer:
Ricardo spends $14 on the backpack and $11 o the binder.
Step-by-step explanation:
First, you have to calculate 56% of the amount Ricardo has to spend on school supplies to find the money he spends on the backpack:
$25*56%=$14
Now, you have to subtract 56% from 100% to find the percentage that he spent on a large binder:
100%-56%=44%
Finally, you have to calculate the 44% of the amount Ricardo has to spend on school supplies to find the money he spends on a large binder:
$25*44%=11
According to this, the answer is that Ricardo spends $14 on the backpack and $11 o the binder.

2. The equation x+2= v-----3x+10 is of the form x+a=v------bx+c ,where a, b, and c are all positive integers and b>1. Using this equation as a model, create your own equation that has extraneous solutions.
(a) Using trial and error with numbers for a, b, and c, create an equation of the form x+a=v-----bx+c, where a, b, and c are all positive integers and b>1 such that 7 is a solution. (Hint: Substitute 7 for x, and choose a value for a. Then square both sides so you can choose a, b, and c that will make the equation true.)
(b) Solve the equation you created in Part 2a.
(c) If your solution in Part 2b did not have an extraneous solution, revise your equation so that 7 is one solution and there is an extraneous solution. If your solution in Part 2b did have an extraneous solution, create another equation with different values of a, b, and c that also has 7 as one solution and an extraneous solution.

Answer:
Short-term investments, also known as marketable securities or temporary investments, are those which can easily be converted to cash, typically within 5 years. Many short-term investments are sold or converted to cash after a period of only 3-12 months. Some common examples of short term investments include CDs, money market accounts, high-yield savings accounts, government bonds and Treasury bills. Usually, these investments are high-quality and highly liquid assets or investment vehicles.

Find the value of x so that the function has the given value.
n(x) = -6x + 2; n(x) = 44
9514 1404 393
Answer:
x = -7
Step-by-step explanation:
Substitute the given value and solve for x
n(x) = -6x +2
44 = -6x + 2
42 = -6x . . . . . subtract 2
-7 = x . . . . . . . divide by -7
n(x) will have the value 44 for x = -7.
Tyrese wants to buy 15 packs of baseball cards. They cost $ 5.00 per pack. There is a 25 % discount before tax if 10 or more packs are purchased. Sales tax is 7 % . Tyrese gives the cashier $ 100 to pay for his baseball cards. How much change will he receive in return?
Answer:
Tyrese will receive $39.81 in return.
Step-by-step explanation:
First, you have to multiply the 15 packs for the cost per pack:
15*$5=$75
As there is a 25% discount before tax if 10 or more packs are purchased, you have to calculate 25% of the total cost for the 15 packs and subtract that amount from the cost:
$75*25%=$18.75
$75-$18.75=$56.25
Then, you have to calculate 7% of the amount with the discount and add that to the cost:
$56.25*7%=$3.93
$56.25+$3.94=$60.19
Now, you can subtract $60.19 from $100 to find the change that Tyrese will receive in return:
$100-$60.19= $39.81
According to this, the answer is that Tyrese will receive $39.81 in return.

163.7°
Undefined
Answer:
b on edge, 16.3
Step-by-step explanation:
trust
The angle between the two given vectors is 16.26°
How to find the angle between two vectors?
Here we have the vectors u = (3, 4) and y = (4, 3).
We know that:
u*y = |u|*|y|*cos(θ)
Then:
u*y = 3*4 + 4*3 = 24
And:
|u| = √(3^2 + 4^2) = √25 = 5 = |y|
Then we have:
24 = 5*5*cos(θ)
24/25 = cos(θ)
To find theta, we apply the inverse cosine function in both sides:
Acos(24/25) = θ = 16.26°

Janet's has X dollars Henny has $8 less than Janet which expression shows how to find how many dollars Hanley has
Answer:
Henny = (x-8) dollars
Step-by-step explanation:
Janet's has x dollars.
Henny has $8 less than Janet. It means, the difference between the dollars own by Janet's and Henny is 8.
Henny has = (x-8) dollars
Hence, the expression that shows dollars Hanley has is (x-8).

write an equation for the n th term of the arithmetic sequence -4, 1, 6, 11 ... Then find a(50)
an equation is: a(n) = _n-_
a(50)= _
Answer:
see explanation
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 4 and d = a₂ - a₁ = 1 - (- 4) = 1 + 4 = 5 , thus
[tex]a_{n}[/tex] = - 4 + 5(n - 1) = - 4 + 5n - 5 = 5n - 9
Then
a(50) = 5(50) - 9 = 250 - 9 = 241

One side of a triangle is twice as long as a second side. The remaining side is 3 larger than the second side. The perimeter is 39m. Find the length of each side.
Answer:
Lengths all the three sides are 9m, 18m and 12m
Step-by-step explanation:
Let us assume the length of the second side to be x m
According to the question:
first side = 2x
third side = x + 3
Applying the formula of perimeter:
Perimeter = length + breadth + height
39 = 2x + x + (x + 3)
39 = 2x + x + x + 3
39 = 4x + 3
39 - 3 = 4x
4x = 36
x = [tex]\frac{36}{4}[/tex]
x = 9
length of the first side (x) = 9 m
length of the second side (2x) =2 × 9 =18 m
length of the third side (x + 3) = 9 + 3 = 12 m
∴ lengths all the three sides are 9m, 18m and 12m
if x=2+√3,then find the value of x-1/x
find each measurement indicated, round your answers to the nearest tenth
Answer:
1. 27.0 m
2. 28.0 degrees
Step-by-step explanation:
1. AB
To find AB, we start by getting the measure of the third angle A
Mathematically;
A + 90 + 51 = 180
The sum of angles in a triangle is 180
A = 180-90-51
A = 39
We then proceed to use the sine rule
Mathematically, the sine rule states that the ratio of the measure of a side and the sine of the angle facing the side is same for each side of the triangle
Thus, with respect to the given triangle;
17/sin 39 = x/sin 90
x = 17sin90/sin 39
x = 27.0 m
Kindly note that we substituted x for AB
2. To find the measure of angle A we use the sine rule as used above, but here we have a missing angle and not a missing side
Thus;
34/sin 127 = 20/sin A
Sin A = (20 sin 127)/34
sin A = 0.469
A = sin^-1 0.469
A = 28.0 degrees

The ratio of right-handed students to left-handed students is 9 to 2. There are 468 right-handed students in the school. How many students are left handed?
Answer: 104 left handed students
Step-by-step explanation:
Ratio: 9:2
We should divide 468 by 9, use the number we find, and then multiply it by 2.
468 / 9 = 52
52 x 2 = 104.
There are 104 left-handed students in the school.
Hope this helps!
