Answer:
Given:
The track is a square with a half circle on its left and right sides.
The area of the square is 128 square feet.
To find:
The length of the track.
Solution:
Let side length of the square be x.
Area of square is
Taking square root on both sides.
From the given table 127.7 is closed to 128. So, is 11.3.
Diameter of circle = Side of square = 11.3.
The track has 2 sides of the square and the distance around 1 complete circle(s).
Radius of circle is
Length of the truck is sum of length of square and radii of two circles.
Therefore, the total length of the track is 22.6 feet

What is (8f–9)–(9f–6)
Hey there!
(8f - 9) - (9f - 6)
= 8f - 9 - 9f + 6
= 8f - 9f - 9 + 6
= -f - 3.
Steps :-
Remove the brackets.Bring the like terms together.Simplify the equation.Hope it helps ya!
Answer:
-1 ( f +3) or -f - 3
Step-by-step explanation:
( 8f - 9 ) - ( 9f - 6 )
Add like terms:
8f - 9f = -1f = -f
-9 - -6 = -3
-f - 3
simplify:
-1 ( f +3)

Eli is in the business of manufacturing phones. He must pay a daily fixed cost to rent the building and equipment, and also pays a cost per phone produced for materials and labor. Let C represent the total cost, in dollars, of producing p phones in a given day. The table below has select values showing the linear relationship between p and C. Determine the additional cost to produce each phone.
Answer:
1 phone costs $175
Step-by-step explanation:
The skeleton equation is C = Px + R, where C is total cost, P is the number of phones, x is the price of phones, and R is the rent
We can find the rate of change by finding slope:
1475 - 775/5 - 1 = 700/4 = 175
Now we can input 775 for total cost, and 1 as the number of phones to find the rent
775 = 1(175) + R
775 = 175 + R
600 = R
The rent is 600
1 phone costs 175

The cost of the previous year's booths and prizes for Class Fun Day was $504. This year's cost of the prizes and booths increased by 8% from the cost of the previous year. Mark knew that the budget for the class day is $725.76. He claimed that 70% of the money will be spent on prizes and the booths.
Use reasoning to explain how Mark's claim is incorrect. What percent of the money will be spent on the prizes and the booths?
The graph of y=f(x) is shown below. Determine the value of x when f(x)=3?
Answer:
f(x) = 3
y = 3
So from the graph the value of y = 3 is found D.
Thus x = -3.
All the best!
The equation of a line given two points needs to be found. Samuel claims that slope-intercept form will generate the equation and Helena claims that point-slope form will find the equation. Who is correct? Explain your reason by describing both forms.
Answer:
Helena is correct in saying that the point-slope form will generate the equation. The point-slope form is written as:
y-y₁ = m(x-x₁), where,
m = (y₂-y₁)/(x₂-x₁) is the slope of the line
(x₁,y₁) and (x₂,y₂) are the coordinates of the two points
On the other hand, the slope-intercept form is written as:
y = mx + b, where,
m is the slope of the line
b is the y-intercept
In this case, since only two points were given, the y-intercept of the line is not readily known. Thus, it is only through the point-slope form that the equation of the line can be determined. This is because it only requires the substitution of the x and y-coordinates of the points in the equation.

Find the value of f(-5).
==========================================================
Explanation:
Locate -5 on the x axis number line. Draw an arrow going upward until you reach the function curve. Then move horizontally until you reach the y axis. You should arrive at y = 4. Therefore, f(-5) = 4 and it means the point (-5, 4) is on the function curve.

Step-by-step explanation:
Answer:
36b - 2c - 6 / 3
Step-by-step explanation:
16b - 1 × 2/3 (c + 3) - 4b
Multiply the numbers:
1) 16b - 1 ×2/3 (c + 3) - 4b
16b - 2/3 (c + 3) - 4b
Combine multiplied terms into a single fraction:
2) 16b - 2/3 (c + 3) - 4b
16b + -2 ( c + 3) / 3 -4b
Distribute:
3) 16b + -2 (c + 3) / 3 -4b
16b + -2c - 6 / 3 -4b
Combine like terms:
4) 16b + -2c -6 / 3 -4b
12b + -2c -6 / 3
Find a Common Denominator:
5) 12b + -2c -6 / 3
3 × 12b / 3 + -2c - 6 / 3
Combine fractions with a Common Denominator:
6) 3 × 12b / 3 + -2c - 6 / 3
3 × 12b - 2c - 6 / 3
Multiply the numbers:
7) 3 × 12b - 2c - 6 / 3
36b - 2c - 6 / 3
SOOO, the answer issssss
36b - 2c - 6 / 3

The expression 5n + 2 can be used to find the total cost in dollars of bowling where n is the number of games bowled and 2 represents the cost of shoe rental. How much will it cost Vincent to bowl 3 games?
quickly please.
Answer: $17
Step-by-step explanation:
5n+2 is the equation we start off with.
He plays 3 games, and since n represents the number of games bowled, we subsitute n with 3.
Our equation looks like this:
5(3)+2
If you solve the equation, you get:
5(3)+2
=15+2
=17
The answer is $17.

Question 3.(Not sure how many more of these i will need to ask help on)
Answer:
80p + 48q - 8
Step-by-step explanation:
just multiply the 8 on the outside of the parentheses by each term inside the parentheses.
8 (10p + 6q - 1)
8*10p = 80p
8*6q = 48q
8* -1 = -8
= 80p + 48q - 8

Find the value of f(-8).
Explanation:
Check out the diagram below. I started at -8 on the x axis number line. This number line is horizontal. Then I went straight down to arrive at the function curve. Afterward, I went directly to the right to get to the y axis. The final destination is y = -2
Therefore, f(-8) = -2

(a) 8b + 5 = 133
(b)
8b = 133 - 5
8b = 128
b = 16
step 1 8b + 5 = 133
step 2 8b = 133 - 5 (moving the five that was plusing have to turn into minus)
8b = 128)( move the 8 that is timing with the b from timing turns into dividing
the answer would be b = 16

If you erased 1/4 of the shaded part below, how much of the original figure will be shaded?
Answer:
[tex]\frac{5}{12}[/tex]
Step-by-step explanation:
[tex]\frac{2}{3} -\frac{1}{4}[/tex]
Find the least common denominator (LCD).
[tex]\frac{2 * 4 }{3*4} - \frac{1*3}{4*3}[/tex]
= [tex]\frac{8}{12} - \frac{3}{12}[/tex]
Substract.
[tex]\frac{8-3}{12}[/tex] = [tex]\frac{5}{12}[/tex]
Hence, [tex]\frac{5}{12}[/tex] of the original figure will be shaded.
