Answer:
Step-by-step explanation:
the constant drain of water is C:
C= (1000-940)/10 = 6 gallons per minute
after x minutes : 1000- 6x ( water left in the tank after x minutes)
for 5 minutes: 1000-6(5)=970
after 20 min.: 1000-6(20)=880
after 30 min.: 1000-6(30)=820
after 27 min.: 1000-6(27)= 838
the rate of flow of water is 6 gallon per minute
Answer:
sina
Step-by-step explanation:
Using the cofunction identity
cos(90 - x) = sinx , then
cos(120 - (30 + a) )
= cos(120 - 30 - a)
= cos(90 - a)
= sina
0.7, 70% are a equivalent decimal and percent
3/4 of 12 is 9
12 - 9 =3
3 sections are left
Answer: True
Let's make 2.2 into a three digit number to calculate and focus better.
⇒ 2.01 < 2.20
2.20 is 0.19 more than the number/decimal 2.01.
So, the answer is True. 2.2 is greater than 2.01.
