Max would have had to have gotten 34 out of 40 questions correct. Here's why:

\frac{x}{40} =  \frac{85}{100} 

(40)(85) = (x)(100)



3400 = 100x

 \frac{3400}{100} = x


34 =x

If f(x) = 2x - 4 and g(x)= -5x + 6, then what is f(g(x))?
Nikitich [7]

Answer:

B. f(g(x)) = -10x + 8

Step-by-step explanation:

When evaluating f(g(x)), substitute what g(x) is in place of g(x).

So instead of

f(g(x))

the function would be:

f(-5x + 6).

Now all you have to do is evaluate this.

To evaluate this function, substitute the value inside the f(x) for all instances of x in the equation.

f(x) = 2x - 4

f(-5x + 6) = 2(-5x + 6) - 4

f(-5x + 6) = -10x + 12 - 4

f(-5x + 6) = -10x + 8

Therefore, f(g(x)) = -10x + 8.

The value of 3 in 46.132 is how many times the value of the 3 in 8.553<br><br>A 10<br>B 1 <br>C 1/10
kifflom [539]

Answer:

The value of 3 in 46.132 is 10 times the value of 3 in 8.553.

Step-by-step explanation:

The value of 3 in 46.132 is in hundredth's place.

The value of 3 in 8.553 is in thousandths place.

We can write as :

For 46.132, its value is \dfrac{3}{100} and for 8.553 its value is \dfrac{3}{1000}.

Taking,

\dfrac{\dfrac{3}{100}}{\dfrac{3}{1000}}=10

So, the value of 3 in 46.132 is 10 times the value of 3 in 8.553. Hence, the correct answer is A.

The main tank has a radius of 70 feet. What is the volume of the quarter-sphered sized tank? Round your answer to the nearest wh
Misha Larkins [42]
Volume of a sphere with radius of 70 feet is:
V =  \frac{4}{3} * \pi * r^{3}

where r is that radius

Because we need quarter sized tank of that radius we need to divide formula for volume by 4

Than we get:
V =  \frac{1}{3} * \pi * r^{3}

V = 359188,76

Rounded:
V = 359189
