Zack measured a rectangular garden at the park. The longer sides each measured 15 feet and were 3 times longer than the shorter sides. If Zack walked all the way around the garden, how far did he walk?
Answers
Given:
The longer sides of a rectangular garden = 15 feet
It were 3 times longer than the shorter sides.
To find:
The total distance covered by Zack if he walked all the way around the garden.
Solution:
Let the shorter side be x.
Longer side = 15 feet
According to given equation, longer side is 3 times longer than the shorter sides.
[tex]15=3x[/tex]
Divide both sides by 3.
[tex]5=x[/tex]
So, the measure of shorter side is 5 feet.
The total distance covered by Zack if he walked all the way around the garden is the perimeter of the garden.
Perimeter of rectangular garden is
[tex]Perimeter=2(length +width)[/tex]
[tex]Perimeter=2(15 +5)[/tex]
[tex]Perimeter=2(20)[/tex]
[tex]Perimeter=40[/tex]
Therefore, the total distance covered by Zack is 40 feet.

A serval, an African wildcat, leaps high above the ground to pounce on its prey. The height of the serval above the ground in relation to the horizontal distance it travels, both measured in feet, is modeled by the given function.
What does the domain of the function represent in this situation?
A.
the horizontal distance the serval travels during its leap
B.
the height of the serval along the path of its leap
C.
the horizontal distance at which the serval reaches its maximum height above the ground
D.
the maximum height the serval reaches above the ground
Answers
Answer:
A. the horizontal distance the serval travels during its leap
Step-by-step explanation:
In this situation, the height along the path that the serval leaps is represented on the y-axis (range value), as against its corresponding horizontal distance on the y-axis (domain value) during the course of its leap.
Therefore, in this situation, the the horizontal distance the serval travels during its leap is the domain of the function.

Answer:
60
Step-by-step explanation:
The exterior angles of the polygon are the supplement of the interior angles, so are ...
180° -174° = 6° . . . . measure of each exterior angle
The sum of exterior angles is 360°, so ...
n(6°) = 360°
n = 360°/6° = 60
The polygon has 60 sides.
Answer:
The polygon has 60 sides.
Step-by-step explanation:
Each interior angle = 174°
Each exterior angle = 180° - 174° = 6°
Sum of all exterior angles = 360°
6x = 360° (x = no. of exterior angles)
x = 360°/6
x = 60
If it has 60 exterior angles it has 60 interior angles.

40
Answers
Answer:
16
Step-by-step explanation:
Since there is always a certain amount of coaches per # of players we have to find that. If there are 20 players and 4 coaches that means 5 players per coach. if there are 35 players and 7 coaches that means again 5 players per coach. Therfore we know that 5 players per coach is constant. If we have 80 players we set up a proportion to solve. 80players / x coaches = 5 players per/ 1 coach. Cross multiply and solve. 80=5x

Substitute the given values:
A= 4
B= 3
C= 2
5(a+b)-3(b+c)
5(4+3)-3(3+2)
Add the numbers:
5(7)-3(5)
5•7 = 35 and 3•5= 15

The sum of the ages of Rudy and his father is 58 years. The difference in their ages is 32 years. How old is each ?
Answers
Answer:
Rudy is 13 years old. Her father is 45 years old.
Step-by-step explanation:
It's very simple actually!
All you need to do is subtract 32:
58 - 32 = 26
Then divide:
26 ÷ 2 = 13
13 is Rudy's age. Let's find her father's age!
We then add 32 back to 13:
32 + 13 = 45
And there you have it!
