Percentage of total hours were spent skiing is 10%
What is the percentage?Percentage is defined as a relative value indicating 100th parts of any quantity. It is denoted by symbol of %.
Given that,
Soccer = 5 hours
Jogging =20 hours
Walking =10 hours
Skiing = 5 hours
Football = 10 hours
Total hours were spent all activity = 5+20+10+5+10=50
Let, percentage of total hours were spent skiing = x
5/50=x/100
5×100=500
500/50=10
x=10
Hence Percentage of total hours were spent skiing is 10%

Patrice and her family went to the movies. The data table below represents the amount of money they spend in dollars, f(x), in terms of the number of tickets, x,
they buy.
PART A
Write a linear function, f(x), that represents the data
PART B
Explain what the slope and y-intercept of f(x) mean in the given context.
Answer:
f(x) = 7.75x + 12.5
The slope represents the cost per movie ticket.
The intercept represents the flat fee paid to see movies.
Step-by-step explanation:
From the data given :
When x = 3 ; f(x) = 35.75
When x = 5 ; f(x) = 51. 25
Linear function :
y = mx + c
f(x) = mx + c
m = slope ; c = intercept
35.75 = 3m + c - - - (1)
51.25 = 5m + c - - - (2)
Subtract
-15.5 = - 2m
m = 15.5 / 2
m = 7.75
From (1)
35.75 = 3m + c
35.75 = 3(7.75) + c
35.75 = 23.25 + c
c = 35.75 - 23.25
c = 12.5
y = 7.75x + 12.5
f(x) = 7.75x + 12.5
B.) The slope represents the cost per movie ticket.
The intercept represents the flat fee paid to see movies.

question 2. the last one
Step-by-step explanation:
Answer:
Step-by-step explanation:
1. 20 a yard and made 100. 100/20=5 yards
20x=100
2. Since they don't give the number of yards they did mow, this would be my answer. I would say half the amount. Since they cut their rates in half, they'll have to cut twice as many to even the amount as before. They would have to cut three - four times as many to make over the original amount. They only have one weekend, so that'll be hard.

Which statement describes the graph of g(x)with respect to the graph of f(x)?
g(x)is translated 7 units right from f(x).
g(x)is translated 7 units up fromf(x).
g(x)is translated 7 units down fromf(x).
g(x)is translated 7 units left fromf(x).
If x=2, f(2)=5*2=10 and g(2)=5*2-7=10-7=3

Determine whether the sequence of mapping rules will lead to the image being congruent to the pre-image (x,y)→(−x, .5y)
Question 2 options:
Yes, this is a reflection which doesn't change the pre-image size
Yes, this is a translation which doesn't change the pre-image size
No, the image will be bigger than the pre-image
No, the image will not be same size as the pre-image
Answer:
No, the image will not be same size as the pre-image
Step-by-step explanation:
0.5y means it's getting shrunk in the y-axis so it is no longer congruent. D is the correct answer because it is no longer the same size as the pre-image.

The shape of an underground pool follows a parabola with the function LaTeX: f\left(x\right)=x^2+8xf ( x ) = x 2 + 8 x. What point represents the bottom of the pool? Group of answer choices
Answer:
The point that represents the bottom of the pool is [tex](x,y) = (-4, -16)[/tex].
Step-by-step explanation:
Given that the shape of the underground pool is a parabola, that is, a second order polynomial. Then, the point that represents the bottom of the pool is the vertex, which is contained in the standard form of the parabola. That is:
[tex]y-k = C\cdot (x-h)^{2}[/tex] (1)
Where:
[tex]x[/tex] - Independent variable, dimensionless.
[tex]y[/tex] - Dependent variable, dimensionless.
[tex]h[/tex], [tex]k[/tex] - Coordinates of the vertex, dimensionless.
[tex]C[/tex] - Constant, dimensionless.
The parabola is represented by [tex]f(x) = x^{2}+8\cdot x[/tex] and we proceed to transform into the desired form:
1) [tex]f(x) = x^{2}+8\cdot x[/tex] Given.
2) [tex]f(x) = (x^{2}+8\cdot x + 16)-16[/tex] Modulative property/Existence of the additive inverse.
3) [tex]f(x) +16 = (x+4)^{2}[/tex] Compatibility with the addition/Modulative property/Existence of the additive inverse/Perfect square trinomial.
4) [tex]y + 16 = (x+4)^{2}[/tex] Notation/Result.
Hence, the point that represents the bottom of the pool is [tex](x,y) = (-4, -16)[/tex].
