This is a trick question. They eat 1/3 of the gallons given. Multiply

1/3 * 1/3 = 1/9 gallons or 0.111 gallons

Answer: Aye aye, cap'in

Step-by-step explanation:

So we start off with our base value, 1/3 gallons.

We are trying to find how many gallons we have eaten, so we do 1/3*1/3, since we need to find what is 1/3rd of that gallon.

For reference, if you wanted to find how much is left over, we multiply by 2/3 since 1-1/3 = 2/3, so there are 2/3 of the 1/3rd gallons left. Not important for solving this problem, but it might help you understand why we decided to multiply by 1/3.

1/3 * 1/3 = 1/9

Our answer is 1/9.

A math class has 3 girls and 7 boys in the 7th grade and 5 girls and 5 boys in the 8th grade the teacher randomly selects a seve

Minchanka [31]

In the 7th and 8th grade combined, there 3+5 girls = 8 girls, and 7+5 boys = 12 boys. If there are only boys and girls, then there are 12+8=20 students in all.

The fraction of girls out of the total is P = 8/20 = 2/5.

Find the formula for an exponential function that passes through the two points given.

goldenfox [79]

Answer:

$y = 7(3^x)$

Step-by-step explanation:

Given

$(x_1,y_1) = (0,7)$

$(x_2,y_2) = (4,567)$

Required

Determine the formula

An exponential function is of the form:

$y = ab^x$

For point $(x_1,y_1) = (0,7)$

$7 = ab^0$

$7 = a*1$

$7 = a$

$a = 7$

For point $(x_2,y_2) = (4,567)$

$567 = ab^4$

Substitute 7 for a

$567 = 7*b^4$

Divide both sides by 7

$81 = b^4$

Take 4th root of both sides

$\sqrt[4]{81} =\sqrt[4]{b^4}$

$\sqrt[4]{81} =b$

$b = \sqrt[4]{81}$

$b = 3$

Substitute 7 for a and 3 for b in $y = ab^x$

$y = 7 * 3^x$

$y = 7(3^x)$

Rewrite 16/9 as a mixed number.

PilotLPTM [1.2K]

To find the answer, to convert a improper into mixed, first take the denominator (9) and find how many times it can go into the numerator (16) FULLY. The answer is 1 time. 1 is the whole number. Then whatever is leftover is the new numerator, and the old denominator is the same. So your answer is 1 7/9

Hope this helps!
