Answer:
D: 850 cm^3
Step-by-step explanation:
You sum the volumes.
Prism is 15*5*7 = 525
Pyramid is 15*5*13/3 = 325
Sum is 850
M / -4 = -2.95
As you can see, the variable m is currently in a fraction with a denominator of -4. So to get ride of the fraction and find m and its value, you should multiply both sides by the denominator of the fraction, which is in our case -4.
So m / -4 = -2.95
(m/-4) * -4 = -2.95 * -4
m = 11.8
You can recheck your answer (very important):
m / -4 = 11.8 / -4 = -2.95
The answer has been approved.

Answer:
llllllllllllllllllllllllllllllllll
Step-by-step explanation:
Hello,
s=48t-16t²
a)
s=0==>16t(3-t)=0==>t=0 or t=3
b)
s>32==>48t-16t²>32===>16(t²-3t+2)<0
Δ=9-8=1
==>16(t-1)(t-2)<0
==>1<t<2 (negative between the roots)
Answer:
(8×5)+(10×20)=240
Step-by-step explanation:
8 (Car wash hourly pay $$) times 5 (hours worked) equals 40(money earned). And 10 (dog walker money $$) times 20 (hour worked) equals 200(money earned). 200(dog walker) plus 40(car washer) is 240. So if you do 5 hours at the car wash and 10 hours of dog walking, you'll earn enough to cover your expenses.
