Answer:
use mathaway it helps all you have to do is take a picture it it will help u with the steps
Since you have to multiple. L×W×H....
The first one has a volume of 400 and the second has a volume of 400...so both prisms have an equal volume but have a differnet shape
Answer:
center: (-10,-4)
radius: 9
Step-by-step explanation:
Let's start off by moving the 35 to the other side and grouping the x and y terms we have
(x²+20x)+(y²+8y)= -35
Next we take the term with the x coeficcent, divide it by 2, and square it
so
for the x we would do (20/2)²=100
and make sure we add that to the 35
(x²+20x+100)+(y²+8y+16)= -35+100+16
next factor everythign to get
(x+10)²+(y+4)²=81
therefore the center is (-10,-4)
and the radius is √81 or 9
Answer:
x > 367
Step-by-step explanation:
set x = # of DVDs they sold
Each DVD costs $15 so the total amount they made is 15x
Since they raised more than $5500
15x > 5500
Divide both sides by 15 to solve the inequality and you get
x > 366.67 and since you can't sell 0.67 of a DVD, round up to get
x > 367 which means that they sold more than 367 DVDs
