Answer:
10 cm²
Step-by-step explanation:
74 088 is the cubed of one side. So you would do [tex]\sqrt[3]{74088}[/tex] which is 42. So one side of the cube is 42. To find the surface area, you would do 6(42x42) which would give you 10584. Remember to put cm²
There are 22 people in a room, if everyone shakes everyone else’s hand exactly one time, how many handshakes would that be total?
There will be 231 handshakes in total
Solution:
There are 22 people in a room
Everyone shakes everyone else’s hand exactly one time
To find: Total number of handshakes in total
Let,
n = total number of people that will shake hands
but since all (total) can't shake hands with themselves, hence we subtract one individual to start the handshaking
(n - 1) = people would each shake hands
hence we multiply both total number persons with people that will shake hands;
n(n - 1)
but that counts every handshake twice, so we have to divide by 2
Therefore;
[tex]\frac{n(n-1)}{2}[/tex]
Here, n = 22
[tex]\frac{n(n-1)}{2} = \frac{22(22-1)}{2} = 11 \times 21 = 231[/tex]
Thus there will be 231 handshakes in total
1. This season, a basketball player has made 34 of 47 free
throws. What is his free throw percentage?
The free throw percentage is 72.34 %
Solution:
Given that, This season, a basketball player has made 34 of 47 free throws
To find: Free throw percentage
The formula used is:
[tex]\text{Free throw percentage} = \frac{\text{number of throws by basketball player}}{\text{total number of throws}} \times 100[/tex]
From given,
Number of throws by basket player = 34
Total number of throws = 47
Therefore,
[tex]\text{Free throw percentage} = \frac{34}{47} \times 100\\\\\text{Free throw percentage} = 0.7234 \times 100\\\\\text{Free throw percentage} =72.34[/tex]
Thus free throw percentage is 72.34 %

81 is 18% of what number? Enter your answer in the box.
Answer:
450
Step-by-step explanation:
If 81 is 18% of a number then we can say that:
x × 0.18 = 81
We multiply by 0.18 because 18% is 0.18 as a decimal. So to work out the real number we divide 81 by 0.18:
81 ÷ 0.18 = 450

Given the system of equations, what is the solution?
3x - 2y + 10 = 0
5y = 4x + 8
{(-34/7, -16/7)}
{(-34/7, 16/7)}
{(34/7, -16/7)}
Answer:
{(-34/7, -16/7)}
Step-by-step explanation:
Rearrange values, multiply to solve for x.
(5) 2y = 3x + 10
(-2) 5y = 4x + 8
Solve for x.
10y = 15x + 50 ↓
-10y = -8x -16
Combine and evaluate.
0 = 7x + 34
Subtract 34 from both sides.
7x = -34
Divide both sides by 7.
x = [tex]\frac{-34}{7}[/tex]
Plugin x value into either equation to solve for y.
2y = (3 × [tex]\frac{-34}{7}[/tex]) + 10
2y = [tex]\frac{-106}{7}[/tex] + 10
2y = [tex]\frac{-32}{7}[/tex]
y = [tex]\frac{-16}{7}[/tex]
Final answer:
By rewriting one equation to isolate y and substituting it into the other, the solution to the system of equations is determined to be {(-34/7, 16/7)}.
Explanation:
The solution to the system of equations provided is found by solving the equations simultaneously. We begin by expressing the second equation in terms of y:
Rewrite the second equation:
5y = 4x + 8
y = (4/5)x + 8/5.
Substitute y in the first equation:
3x - 2((4/5)x + 8/5) + 10 = 0.
Simplify and solve for x:
(3 - 8/5)x + (10 - 16/5) = 0
which gives us-
x = -34/7
Substitute x back into y = (4/5)x + 8/5 to find
y = 16/7
Thus, the solution to the system of equations is {(-34/7, 16/7)}.
GIVING BRAINLIEST Write a proportion that could be used to solve for each variable. Then solve. 7 pencils for $1.68 p pencils for $2.88 a. 7.1.68 = p/2.88; p = 10 c. 1.68/7 = p/2.88; p = 0.7 b. 7/1.68 = p/2.88; p = 12 d. 7/2.88 = p/1.68; p = 4
The proportion that could be used to solve for the variable is:
[tex]\frac{7}{1.68}=\frac{p}{2.88}[/tex] ; p = 12 ⇒ b
Step-by-step explanation:
Direct proportion means that two (or more) quantities increase or decrease in the same ratio
y = k x is the equation of direct proportion, where k is the constant of proportionality[tex]\frac{y_{1}}{x_{1}}=\frac{y_{2}}{x_{2}}=k[/tex] is the another way to write a proportionThe number of pencils and the cost of them is increased together or decreased together
∴ The number of the pencils and their costs are in direct proportion
- By using the 2nd rule above
∵ The cost of the 7 pencils is $1.68
∵ The cost of p pencils is $2.88
∴ [tex]\frac{7}{1.68}=\frac{p}{2.88}[/tex]
The proportion that could be used to solve for the variable is: [tex]\frac{7}{1.68}=\frac{p}{2.88}[/tex]
∵ [tex]\frac{7}{1.68}=\frac{p}{2.88}[/tex]
- By using cross multiplication
∴ p × 1.68 = 7 × 2.88
∴ 1.68 p = 20.16
- Divide both sides by 1.68
∴ p = 12
The value of variable p is 12

The number −6 is 2 more than an unknown number. Find the unknown number.
The unknown number is -8.
To find the unknown number, we can set up an equation based on the given information.
We are told that -6 is 2 more than the unknown number, so we can represent this as:
Unknown number + 2 = -6
To isolate the unknown number, we need to subtract 2 from both sides of the equation:
Unknown number = -6 - 2
Unknown number = -8
So, the unknown number is -8. This means that when you add 2 to -8, you get -6, which satisfies the condition given in the problem.
In summary, by setting up and solving the equation Unknown number + 2 = -6, we determined that the unknown number is -8.
This equation represents the relationship between the unknown number and the given value of -6, where -6 is 2 more than the unknown number, as specified in the problem statement.

7. If 40% of a given number is 8, then what is 15% of the
given number?
Answer:
3
Step-by-step explanation:
First find the given number(x)
40% : 40/100 × x = 8
the value of x is 20.
Next find 15% of 20
15/100 × 20 = 3
The 15% of 20 is 3.
What is percentage?Percentage, a relative value indicating hundredth parts of any quantity. One percent (symbolized 1%) is a hundredth part; thus, 100 percent represents the entirety and 200 percent specifies twice the given quantity.
Given:
40% of a given number is 8
let the number be x
So, 40% of x = 8
40/100*x= 8
x= 8*100/40
x= 800/40
x= 20

Answer:
y = [tex]\frac{1}{4}[/tex] x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) =( 8, - 3) and (x₂, y₂ ) = (0, - 5)
m = [tex]\frac{-5+3}{0-8}[/tex] = [tex]\frac{-2}{-8}[/tex] = [tex]\frac{1}{4}[/tex]
Note the line crosses the y- axis at (0, - 5 ) ⇒ c = - 5
y = [tex]\frac{1}{4}[/tex] x - 5 ← equation of line
[tex] \frac{y - y1}{y2 - y1} = \frac{x - x1}{x2 - x1} \\ \frac{y - ( - 3)}{ - 5 - ( - 3)} = \frac{x - 8}{0 - 8} \\ \frac{y + 3}{ - 2} = \frac{x - 8}{ - 8} \\ - 8(y + 3) = - 2(x - 8) \\ - 8y - 24 = - 2x + 16 \\ 2x - 8y = 40[/tex]

Greatest common factor of 16k - 24
Answer:
8
Step-by-step explanation:
The greatest common factor of 16k - 24 is 8.
Explanation:The first step to find the greatest common factor (GCF) of 16k - 24 is to factor out any common terms. In this case, both 16k and 24 are divisible by 8, so we can factor out an 8: 8(2k - 3). Now, we need to look at the expression inside the parentheses, 2k - 3, and try to factor out any common terms. However, since 2k - 3 does not have any common factors, the GCF of 16k - 24 is simply 8.
