Volume of the two semicircle prism = π(2)²(4) = 16π = 50.27ft³
Volume of the rectangle prism = 12 x 4 x 4 = 192 ft³
Volume of the whole prism = 50.27 + 192 = 242.27 ft³
Answer: Volume = 242.27 ft³
Answer: 1.18 dollars
Step-by-step explanation:
Given that:
E = Euros
D = US dollars
If the equation showing the relationship between Euros and Dollar
is E = 17/20D
To find the equivalent amount of dollars for 1 euros, substitute E for 1 in the formula and make D the subject of formula
1 = 17/20 D
Cross multiply
17D = 20
D = 20/17
D = 1.18 dollars approximately
Therefore, 1.18 dollars have the same value as 1 euro.
unit rate of speed is 0.27 miles per minute .
<u>Step-by-step explanation:</u>
Here we have , it took marjorie 15 minutes to drive from her house to her daughter's school. If the school was 4 miles away from her house, We need to find what was her unit rate of speed . Let's find out:
We know that ,
...........(1)
According to question we have following parameters as :
![Distance = 4 miles\\Time=15min](https://tex.z-dn.net/?f=Distance%20%3D%204%20miles%5C%5CTime%3D15min)
Putting these value in equation (1) we get:
⇒ ![Speed = \frac{Distance}{Time}](https://tex.z-dn.net/?f=Speed%20%3D%20%5Cfrac%7BDistance%7D%7BTime%7D)
⇒ ![Speed = \frac{4miles}{15min}](https://tex.z-dn.net/?f=Speed%20%3D%20%5Cfrac%7B4miles%7D%7B15min%7D)
⇒ ![Speed = (\frac{4}{15} )\frac{miles}{min}](https://tex.z-dn.net/?f=Speed%20%3D%20%28%5Cfrac%7B4%7D%7B15%7D%20%29%5Cfrac%7Bmiles%7D%7Bmin%7D)
⇒ ![Speed = (0.27 )\frac{miles}{min}](https://tex.z-dn.net/?f=Speed%20%3D%20%280.27%20%29%5Cfrac%7Bmiles%7D%7Bmin%7D)
Therefore , unit rate of speed is 0.27 miles per minute .
Step-by-step explanation:
5(-7)-2(-7+3)^2
=-35 - 2(-4)^2
=-35 - 2x16
=-35 - 32
=-67
Am i right? :o
