The owners of an amusement park want to add more rides and an arcade in an open field.Beloe is a sketch of their plan. the owners do not know all of the measurements of the field
Answers
Answer:
Step-by-step explanation:
Formula to get the area of a rectangle,
Area = Length × Width
Area of rides area = 30 × n
= 30n yds²
Area of the arcade = 30 × 40 yds²
Area of the whole field = Area of rides + Area of Arcade
Area = [30n + 30(40)] square yards
Length of whole field = (n + 40) yds
Width of whole field = 30 yds
Area of the whole field = 30(n + 40) square yards

Answer choices: .691, -.14, .24, -.77
Answers
Answer:
Weakest value = 0.0196
Strongest value = 0.5929
Step-by-step explanation:
Given:
Choices
0.691
-0.14
-0.24
-0.77
Computation:
0.691² = 0.477481
-0.14² = 0.0196
-0.24² = 0.0576
-0.77² = 0.5929
Weakest value = 0.0196
Strongest value = 0.5929
The cube of y varies directly as z. When y = 8, z = 8. Heather’s work finding the value of y when z = 64 is shown:
y^3 = kz
8 = k x 8
1 = k
y^3 = 1 x 64
y^3 = 64
y = 4
What is the first error, if any, in Heather’s work?
A. She did not make any errors.
B. She substituted incorrectly when calculating the constant of variation.
C. She cubed the wrong variable when making her equation.
D. She used an equation that models inverse variation instead of direct variation.
Answers
Answer:
Step-by-step explanation:
If the cube of y varies directly as z, then;
y³ ∝ z
y³ = kz
k is the constant of proportionality
y³ = kz
When y = 8, z = 8.
8³ = 8k
k = 8³ /8
k = 64
To get the value y when z = 64, we will have;
y³ = kz
y³ = 64(64)
y³ = 4096
y= ∛4096
y = 16
Hence the value of y is 16

A boat takes 2 hours to travel 15 miles upriver against the current. If the rate of the boat in still water is 13 miles per hour what is the rate of the current?
Answers
Answer:
The rate of the current is 5.5 miles per hour
Step-by-step explanation:
Relative Speeds
The boat takes 2 hours to travel 15 miles upriver against the current. The speed is 15/2 = 7.5 miles per hour.
Since the boat in still water can travel at 13 miles per hour, it means the current subtracts its speed from the speed of the boat:
Vcurrent = 13 mi/h - 7.5 mi/h
Vcurrent = 5.5 mi/h
The rate of the current is 5.5 miles per hour

the present ages of two brothers are 15 years and 22 years respectively after how many years will the product of their ages be 408
Answers
Step-by-step explanation:
Let (15 + x) and (22 + x) be the future ages of the brothers.
We have (15 + x)(22 + x) = 330 + 37x + x² = 408
Therefore x² + 37x = 78 and x = 2.
Hence the answer is 2 years later.
15+x+22+x= 408
Collect like terms
37+2x=408
Move 37 to the other side as a negative number
2x=371
Divide both sides by 2
371/2 is 185.5
So, after 185.5 years, their ages will add up to be 408

in the term 4p, the variable p is raised to the power of 0 or 1 ?
Answers
Answer:
1
Step-by-step explanation:
anything raised to the power of 0 would equal 1 and p doesn't equal 1 here.
Answer:
4 or 0
Step-by-step explanation:
well if the variable p became 0 the term 4p would look more like this 4(0) or 4 * 0 making the answer be 0
If the variable was changed into 1 the term 4p would become 4(1) or 4 * 1 as of such the answer would be 4.
now if you are raising p to a 0 so the term is more like this: 4p to the power of 0 then your answer would be 1. Because p would change to 0.
Now if you had 4p to the raised power of 1 then your answer would be 4 because p was changed to a 4.
I hope this answers your question.

20. In the 7th grade, there are 84 students

are 2 gymnasts.
B. For every 5 gymnasts, there are 2
hockey players.
C. For every 7 hockey players, there
are 2 gymnasts.
D. For every 7 gymnasts, there are 5
hockey players.
Answers
Answer:
A. For every 5 hockey players there is 2 gymnast's.
Step-by-step explanation:
So 24 students out of 84 are gymnast's.
To find how many hockey players there are you subtract 24 from 84.
84-24=60
So there is 60 Hockey players.
So now you go down the option choices and look which one is correct.
So the first choice says 5 hockey players for 2 gymnasts.
second choice 5 gymnast for every 2 hockey player. well we know that's wrong because you cant get to 24 counting by 5's. So B is not correct
C. 7 hockey players for every 2 gymnast well that one is also wrong because you cant get to 60 counting by 7's so C. is wrong
D. Is the same as C but switch soo we know that one is also wrong the last one left would be A.
5 hockey players for very 2 gymnast
so you count by 2s to see if you can get to 24 you can. It would take you 12 2 to get to 24 so we know thats right
Now we see if we can get to 60 counting by 5s we can so it will take you 12 5s to get 60 so we know Answer choice A is correct.

Step-by-step explanation:

The attached graph
Required
Determine the number of white paints per yellow paints
The interpretation of this question is to determine the slope or rate of the graph.
Represent the yellow paints with x and the white with y
So, we have:
[tex](x_1,y_1) = (3,21)[/tex]
[tex](x_2,y_2) = (9,63)[/tex]
The slope is then calculated as:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{63- 21}{9 - 3}[/tex]
[tex]m = \frac{42}{6}[/tex]
[tex]m = 7[/tex]
Hence, 7 white paints are needed per 1 yellow paint

Substitute P = sinx
Sinx>3 and sinx>-1
x > sin^-1 3 and x > sin^-1 (-1)
x>-90°
Since sin is negative in the 3rd and 4th quadrant
