Answer: -8.8+13.4 is 22.2 so after that im guesing you have to solve -4.25 divided by 00.5 is 85

Comment
I think you should try this one yourself after I post my answer. Estimation is a very valuable tool -- the more you use it, the handier it gets.
Formulas
pi = 3
V = 4/3 * pi * r^3
Givens
r = 2
pi = 3
Solution
V = 4/3 * pi * r^3 Substitute values for symbols
V = 4/3 * 3 * 2^3 Cancel the 3s
V = 4 * 2^3 Expand the 2s
V = 4 * 2 * 2 * 2 Find V
V = 32
Answer: In 10 hours, 4000 bacteria will be present.
Step-by-step explanation:
Given that 2000 bacteria grew to 2400 in 2 hours,
growth/ increase rate = 2400 - 2000
= 400 bacteria increase in 2 hours
Per hour is therefore 400/2 = 200 bacteria increase per hour
If the bacteria increases by 200 per hour
If 200 = 1 hour
X = 10 hours
We cross multiply:
X = 200 x 10
X = 2000
Therefore, a culture with 2000 bacteria at the same growth rate will have increased by additional 2000 in 10 hours
So, after 10 hours, number of bacteria will be 2000 + 2000 = 4000 bacteria
Answer:
The equation to this word problem are:
x ≥ 30 ...... (1)
x ≥ y ...... (2)
x + y ≤ 100 ..... (3)
Step-by-step explanation:
Here, the given question is INCOMPLETE.
A private school admits no more than 100 students every year. additionally, at least 30 of these students must be girls, x and the school admits at least as many girls as boys, y. What are the equation to this word problem.
Let us assume the number of girls admitted in the school = x
At least 30 of these students must be girls.
⇒ x ≥ 30 ...... (1)
Let us assume the number of boys admitted in the school = y
The school admits at least as many girls as boys.
⇒ x ≥ y ...... (2)
Also, TOTAL STUDENTS = No more than 100
So, Total Number of ( Boys + Girls) ≤ 100
⇒ x + y ≤ 100 ..... (3)
Hence, the the equation to this word problem are:
x ≥ 30 ...... (1)
x ≥ y ...... (2)
x + y ≤ 100 ..... (3)
