Answer:
11.25 m
Step-by-step explanation:
45 divide by 4
because the Apple tree is 45 the size of pear tree
So there are 15 food booths and 20 game booths. Food booths cost 100 dollars. Game booths cost 50.
100 * 15 = 1500
50 * 20 = 1000
And 5 dollars extra for a day, and 7 dollars extra for a day. Multiply by how many days (d).
7 * d = 7d.
5 * d = 5d.
This means that the expression is:
1500 + 5d + 50 + 7d.
1550 + 12d.
-3 + -17 = -(3+17) = -20
Note:
When adding 2 negatives, you add the numbers and put a minus sign in front of your answer, when adding a positive and a negative number, always put the positive number first and then remove the + sign and subtract.
Hope this helped!
Answer: Option B
16.8 minutes
Step-by-step explanation:
Machine A produces 75 fishing lures per minute.
Machine B produces 50 fishing lures per minute.
Let's call t time in minutes.
So we want to know how long it will take to produce 2100 fishing lures
We propose the following equation
![75t + 50t = 2100](https://tex.z-dn.net/?f=75t%20%2B%2050t%20%3D%202100)
Now we solve for t
![125t = 2100](https://tex.z-dn.net/?f=125t%20%3D%202100)
![t = 16.8\ min](https://tex.z-dn.net/?f=t%20%3D%2016.8%5C%20min)
The answer is Option B
Answer:
![\large\boxed{P=(16+36x)\ ft}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7BP%3D%2816%2B36x%29%5C%20ft%7D)
Step-by-step explanation:
The formula of an area of a rectangle:
![A=bh](https://tex.z-dn.net/?f=A%3Dbh)
b - base
h - height
We have A = 144x ft² and h = 8. Substitute and solve for b:
<em>divide both sides by 8</em>
![b=18x\ ft](https://tex.z-dn.net/?f=b%3D18x%5C%20ft)
The formula of a perimeter of a rectangle:
![P=2b+2h](https://tex.z-dn.net/?f=P%3D2b%2B2h)
Substitute:
![P=2(18x)+2(8)=36x+16](https://tex.z-dn.net/?f=P%3D2%2818x%29%2B2%288%29%3D36x%2B16)
