The information provided are:
Tom made a square measuring 8 feet by 8 feet.He had 18 friends stand inside it as if they are watching a band at a small club.The area of the square is:
A = (side)²
[tex]=(8\ \text{feet})^{2}\\\\=64\ \text{feet}^{2}[/tex]
The number of people standing insider the square is:
n = 18
Compute the ration of n to A as follows:
[tex]n:A=18:64[/tex]
[tex]=\frac{18}{64}\\\\=\frac{9}{32}\\\\=9:32[/tex]
Thus, the ratio of this number to the rectangle’s area is 9:32.

Answer:
B
Step-by-step explanation:
∠ CBD = ∠ ABE ( vertical angles ), thus
7x - 6 = 5x + 14 ( subtract 5x from both sides )
2x - 6 = 14 ( add 6 to both sides )
2x = 20 ( divide both sides by 2 )
x = 10
Thus
∠ ABE = 5x + 14 = 5(10) + 14 = 50 + 14 = 64° → B

The distance between two communication towers is 12.654 miles. What is this distance rounded to the nearest tenth of a mile?
Answer:
12.7 miles
Step-by-step explanation:
Note the place values:
12.654
1 (tens value)
2 (ones value)
.
6 (tenths value)
5 (hundredths value)
4 (thousandths value)
~
You are rounding to the nearest tenths value. Note that when rounding, you look at the value directly next to the one you are solving for. If the digit is 5 or greater, round up. If it is 4 or less, round down.
In this case, the hundredths value is a 5, so round up.
12.654 miles rounded to the nearest tenths value is 12.7
12.7 miles is your answer.
What is the value of the expression below when z = 6
Answer:
81
Step-by-step explanation:
[tex]2z^2+2z-3[/tex]
Using PEMDAS/BODMAS, we will have to do the exponent first, which is [tex]z^{2}[/tex].
Substitute the variable z with 6, since z = 6.
[tex]2(6^{2} )+2(6)-3[/tex]
[tex]6^{2} =36[/tex].
Thus, we will get
[tex]2(36)+2(6)-3[/tex]
Solve the multiplication next.
[tex]72+12-3[/tex]
Finally, add/subtract the numbers:
[tex]84-3[/tex]

The value of the equation 2z² + 2z - 3 at 'z' equal to 6 is 81.
What is substitution?Substitution in mathematics is when we replace some specific numerical values to variables according to our wants or given in the problem.
Given, A quadratic equation 2z² + 2z - 3.
Now, The value of the equation at z = 6 can be obtained if we replace the variable z with it's numerical value which is,
= 2(6)² + 2(6) - 3.
= 2(36) + 12 - 3.
= 72 + 9.
= 81.

Libby donated $50 during the first month of the year. If she makes three additional donations of equal amounts during the year, how much will she need to donate each time to be in the Silver category?
Answer:
She will donate P-50/3 each time
Step-by-step explanation:
Now assuming total donation needed to be in the silver category Is P
We can assume also the three additional and equal donations be Q
So
Then 50 + 3Q = P
So we still don't know P
We can get Q by saying
3Q= P - 50
Q = (P - 50) /3

The required integers are 3 and 5.
It is required to find the integers.
What is integer?An integer is a whole number (not a fractional number) that can be positive, negative, or zero. Zero is not a fraction or decimal of any number. It is neither positive nor negative.
Given:
Let smallest number as x
the Largest number as (x+2)
According to given question we have,
(x+2)=2x-1
3=2x-x
∴x=3
Smallest number=3
The Largest number =(x+2)=3+2=5

which of the following shows the correct solution steps and solution to 3x+2=17?
Answer:
[tex]\huge\boxed{\sf x = 5}[/tex]
Step-by-step explanation:
[tex]\sf 3x + 2= 17[/tex]
Subtracting 2 to both sides
[tex]\sf 3x = 17-2\\3x = 15[/tex]
Dividing both sides by 3
[tex]\sf x = 15/3\\x = 5[/tex]
The correct solution to the equation 3x + 2 = 17 is x = 5.
Let's find the correct solution to the equation 3x + 2 = 17:
Step 1: Subtract 2 from both sides to isolate the term with 'x':
3x + 2 - 2 = 17 - 2
3x = 15
Step 2: Divide both sides by 3 to solve for 'x':
3x / 3 = 15 / 3
x = 5
So, the correct solution to the equation 3x + 2 = 17 is x = 5.

Jenny needs to sew two pieces of fabric together. One of the pieces is 3 1/12 inches and the other one is 6 5/8. What is the length of the pierce of fabric
Answer:
9 17/24in
Step-by-step explanation:
3 1/12 + 6 5/8 = length of fabric
We can add 3 and 6 since they are whole inches.
3 + 6 = 9
Now we add the fractions
1/12 + 5/8
We need to find a common denominator.
Each number goes into 24 so
1/12*(2/2) = 2/24 and 5/8*(3/3) = 15/24
2/24 + 15/24 = 17/24
So the total length of fabric is 9 17/24in

Herb owanda is a computer operator for data base, inc. He earns $38,600 a year he is single and is paid on a weekly basis how much is withheld from each weekly paycheck for state taxes?
Answer: $14.85
Step-by-step explanation:
given data:
yearly earnings = $38,600
there are 52weeks in a year, so his weekly wages
= $38,600/52
= $742.31
his state tax rate falls under the 2% rate due to his income
= 2/100 * $38,600
= $772/52
= $14.85 is withheld from his weekly wages for the state tax.
