1) 25% of 176 = 44
2) 90% of 20 = 18
3) 24 is 80% of 30

1. 25% if 1/4, so we want to find 1/4 of 176. Best way to get the result is just divide 176 by 4, so 176:4=44 - its the answer.

2. To get the answer we can use proportion
100% -----------20
90% ---------- x
crossmultiply now
100x=90*20
100x=1800     /:100        divide both sides by 100
x=18 - its the answer

3. Similar problem
24 ---------- x
30 ---------- 100%
crossmultiply now
24*100%=30x 
2400%=30x     /:30 divide both sides by 30
2400%:30=x
80%=x - its the answer

The water level in a tank can be modeled by the function h(t)=8cos(pi t /7)+11.5, where t is the number of
denis23 [38]

Answer:

NO amount of hour passed between two consecutive times when the water in the tank is at its maximum height

Step-by-step explanation:

Given the water tank level modelled by the function h(t)=8cos(pi t /7)+11.5. At maximum height, the velocity of the water tank is zero

Velocity is the change in distance with respect to time.

V = {d(h(t)}/dt = -8π/7sin(πt/7)

At maximum height, -8π/7sin(πt/7) = 0

-Sin(πt/7) = 0

sin(πt/7) = 0

Taking the arcsin of both sides

arcsin(sin(πt/7)) = arcsin0

πt/7 = 0

t = 0

This shows that NO hour passed between two consecutive times when the water in the tank is at its maximum height

Find the difference PLSSSSSSSSSSSSSSSSSSSSSSSSS
Aneli [31]

Answer:

-1 5/9

Step-by-step explanation:

so first, simplify the signs so they don’t confuse you,

-5/6 - 17/18 + 2/9 (Since there are two negatives near the end, and their tecxhnically being mulitplied, -2/9*-1 (I added 1 for place holder) and when you multiply a negatives by a negative, you get a positive.

So find the lcm of the denominators which is 18 in this case

-15/18 - 17/18 + 4/18

Now solve the problem from left to right

you’ll get -1 5/9 if you simplified
