Answer:
The equation that can be used to determine the number of rounds that Emma golfs is:
x=(c-7.50)/6.25
Step-by-step explanation:
From the information given, the total amount Emma pays to go miniature golfing is equal to the price of the admission ticket plus the result of multiplying the price per round of golf for the number of rounds and according to this, the equation would be:
c=7.50+6.25x, where:
c is the total cost for Emma to go miniature golfing
x is the number of rounds
Now, you can solve for x to determine the equation that can be used to find the number of rounds that Emma golfs:
x=(c-7.50)/6.25
You can replace c with 26.25:
x=(26.25-7.50)/6.25
x=18.75/6.25
x=3
The average distance from earth to the sun is 92.95 million miles. the actual distance varies from the average by up to 1.55 million miles. write and solve an absolute value equation to find the minimum and maximum distance from each to the sun. use d for distance.
The maximum and minimum distance from Earth to the Sun are 94.5million miles and 91.4million miles respectively.
Given that the average distance from Earth to the Sun is 92.95 million miles, if the actual distance varies from the average by up to 1.55 million miles, the then;
Maximum distance = average distance + variation
Minimum distance = average distance - variation
Maximum distance = 92.95 million + 1.55million
Maximum distance = 94.5million miles
Minimum distance = 92.95 million - 1.55million
Minimum distance = 91.4million miles
Hence the maximum and minimum distance from Earth to the Sun are 94.5million miles and 91.4million miles respectively.

Answer: Choice C
[tex]y = x^2+2, \ x \ge 0[/tex]
=============================================
Work Shown:
[tex]f(x) = \sqrt{x-2}\\\\y = \sqrt{x-2}\\\\x = \sqrt{y-2} \ \text{ swap x and y}\\\\x^2 = y-2 \ \text{ square both sides}\\\\y = x^2+2\\\\f^{-1}(x) = x^2+2\\\\[/tex]
Since the range of f(x) is [tex]y \ge 0[/tex] this means the domain of the inverse will be [tex]x \ge 0[/tex]
The domain and range swap when you go from the original function to the inverse, or vice versa (due to x and y swapping)
So we must state the inverse is [tex]y = x^2+2 , \ x \ge 0[/tex]

116= -4 + 5(-6 - 5a)
8m + 4(4m -5) = -92
-3(8 - 6x) = -96
-126 = -3 (6+6x)
-8 -8(5a + 7)=-224
-2(-5x -1) = 82
-7(4x + 6) = -182
Answer:
#1) 116= -4 + 5(-6 - 5a) : a = -6
#2) 8m + 4(4m -5) = -92 : m = -3
#3) -3(8 - 6x) = -96 : x = -4
#4) -126 = -3 (6+6x) : x = 6
#5) -8 -8(5a + 7)=-224 : a = 4
#6) -2(-5x -1) = 82 : x = 8
#7) -7(4x + 6) = -182 :x = 5
Step-by-step explanation:
Remember: An equation must be equal at all times. This means if something is added to one side, it must also be added to the other. This holds true for addition, subtraction, division, and multiplication.
Problem 1:
116= -4 + 5(-6 - 5a)
move the -4 to the left side by adding 4 to both sides:
116 + 4 = -4 + 5(-6 - 5a) + 4
now 120 = 5(-6 - 5a)
divide both sides by 5:
120/5 = (5(-6 - 5a))/5
now 24 = -6 - 5a
move the -6 to the left side by adding 6 to both sides:
24 + 6 = -6 - 5a + 6
now 30 = - 5a
divide each side by -5:
(30)/-5 = (- 5a)/ -5
now -6 = a or a = -6
___________________________
Problem 2:
8m + 4(4m -5) = -92
begin by diving both sides by 4:
(8m + 4(4m -5))/4 = (-92)/4
now 2m + 4m - 5 = -23
move the -5 to the right side by adding 5 to both sides:
2m + 4m - 5 + 5 = -23 + 5
now 2m + 4m = -18
restate the left side and combine:
now 6m = -18
divide both sides by 6:
6m/6 = -18/6
so m = -3
___________________________
Problem 3:
-3(8 - 6x) = -96
divide both sides by - 3:
(-3(8 - 6x)) / -3 = -96/-3
now 8 - 6x = 32
move 8 to right side by subtracting 8 from both sides:
8 - 6x - 8 = 32 - 8
now -6x = 24
divide both sides by -6:
-6x/ -6 = 24/-6
x = -4
___________________________
Problem 4:
-126 = -3 (6+6x)
divide both sides by - 3:
-126/-3 = (-3 (6+6x)) /-3
now 42 = 6 + 6x
move 6 to left side by subtracting 6 from both sidesL
42 - 6 = 6 + 6x - 6
now 36 = 6x
divide both sides by 6:
36/6 = 6x/6
x = 6
___________________________
Problem 5:
-8 - 8(5a + 7)= -224
add 8 to both sides:
-8 - 8(5a + 7) + 8 = -224 + 8
now -8(5a + 7) = - 216
divide both sides by -8:
(- 8(5a + 7))/-8 = - 216 /-8
now 5a + 7 = 27
move 7 to right side by subtracting 7 from both sides:
5a + 7 - 7 = 27 - 7
now 5a = 20
divide both sides by 5:
5a/5 = 20/5
a = 4
___________________________
Problem 6:
-2(-5x -1) = 82
divide both sides by -2:
(-2(-5x -1))/-2 = 82/-2
now -5x -1 = -41
move -1 to right side by adding 1 to both sides:
-5x - 1 + 1= -41 + 1
now -5x = -40
divide both sides by -5:
-5x/-5 = -40/-5
x = 8
___________________________
Problem 7:
-7(4x + 6) = -182
divide both sides by -7:
(-7(4x + 6))/-7 = -182/-7
now 4x + 6 = 26
move 6 to right side by subtracting 6 from both sides:
4x + 6 - 6 = 26 - 6
now 4x = 20
divide both sides by 4:
4x/4 = 20/4
x = 5
Emilio has 2 quarters, 4 dimes, 3 nickels and 5 pennies. How much money does Emilio have in all?
Answer:
$1.10
Step-by-step explanation:
What we know:
Emilio has 2 quarters, 4 dimes, 3 nickels, and 5 pennies.
Quarters = 0.25 * 2
Dimes = 0.1 * 4
Nickels = 0.05 * 3
Pennies = 0.01 * 5
$0.50 + $0.40 + $0.15 + $0.05
$0.90 + $0.20 = $1.10 in total

What’s the side and angles?
Answer:
I think that the side length is 25.8 and the angle length is 180 degrees
Step-by-step explanation:
I'm not 100% sure but all I did was add the side lengths to get 25.8 (8.6 + 8.6 + 8.6) and the angle length is 180 degrees (because all triangles has to equal to 180 degrees and 60 plus 60 plus 60 is equal to 180).
There you go. Just to remind you that I'm not 100% sure about this answer, but hope this helps.

Answer: the original slope is 3/2
The perpendicular slope is -2/3
Slope is rise/run
Step-by-step explanation: For the original slope get
Find coordinates where the graphed line crosses the grid lines at the intersections. Here, (0,-2) and (2,1) Count the number of squares vertically. That is the rise. It is the difference in y-values. It is the numerator of the fraction. Then count the squares horizontally to get the run. That is the denominator of the fraction.
It is possible to use the expression [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex] to calculate the slope.
[tex]\frac{1-(-2)}{2-0} = 3/2[/tex]
To find the perpendicular slope, reverse the sign and use the reciprocal of the original fraction.
The reciprocal of 3/2 is 2/3. The opposite sign is negative. -2/3

A statue in the park is 24 feet tall and has a width of 36 inches. Chase was in
ceramics class and decided to make a model of the statue. The model is 16 inches
tall. How wide is the model (to the nearest tenth of an inch)?
Answer:
22.33 feet tall / 267.96 inches tall
Step-by-step explanation:
The statue is 36 inches wide. If Chase made his model of the statue 16 inches wide, he decreased it by 20 inches. Now change the inches into feet. 36 inches would be 3 feet, 16 inches would be 1.33 feet and 20 inches would be 1.67 feet. 24ft - 1.67 = 22.33ft. Now change the answers to inches. 22.33ft will be 267.96 inches tall.

How many perfect cube divisors does 160,000 have?
Answer:
160,000 has three(3) perfect cube divisors namely;. 8, 8 and 125
Step-by-step explanation:
To determine how many perfect cube divisors 160,000 has;
We first need to highlight the factors of 160,000 as follows;
(2 × 2 × 2) × (2 × 2 × 2) × 2 × 2 × (5 × 5 × 5) × 5
As such, the product of numbers in each bracket yield a perfect cube; the expression above then becomes;
2 × 2 × 5 × 8 × 8 × 125.
Therefore, 160,000 has three(3) perfect cube divisors namely;. 8, 8 and 125
