A boat can travel 20 miles on 10 gallons of gasoline. How much gasoline will it need to go 34 miles?​
Irina-Kira [14]

Answer:

20 divided by 10 is 2 so for every 2 miles it travels it uses 1 gallon of gasoline. 20 + 14 is 34 so you divide 14 by 2 to get 7. then you add 10+7 to get 17. it will take 17 gallons of gasoline to go 34 miles

Find the inverse of the given function
xenn [34]

For this case, we must find the inverse of the following function:

f (x) = \frac {5x + 1} {- x + 7}\\x\neq 7

To find the inverse we follow the steps below:

y = \frac {5x + 1} {- x + 7}

We rewrite the denominator:

y = \frac {5x + 1} {- (x-7)}\\y = - \frac {5x + 1} {(x-7)}

We exchange variables:

x = - \frac{5y + 1} {(y-7)}

We solve for y:

We multiply on both sides of the equation by (y-7)

x (y-7) = - 5y-1\\xy-7x = -5y-1

We subtract xy on both sides of the equation:

-7x = -5y-1-xy

We add 1 to both sides:

-7x + 1 = -5y-xy

We factor for y:

-7x + 1 = y (-5-x)

We divide both sides by (-5-x):

y = \frac {-7x + 1} {- 5-x}

So, we have:

f ^ {- 1} (x) = \frac {-7x + 1} {- 5-x}

Answer:

f ^ {- 1} (x) = \frac {-7x + 1} {- 5-x}

x\neq -5

Fruit snacks are Becky's favorite treat, but she especially loves the grape ones! A jumbo box
AveGali [126]

Answer:

10\frac{7}{15}  in

Step-by-step explanation:

Use the volume formula for a rectangular prism, V = lwh

Plug in the volume, length, and width, then solve for the height

V = lwh

157 = (5)(3)(h)

157 = 15h

10\frac{7}{15} = h

So, the box's height is 10\frac{7}{15} in

3. What is the Median Average of Shoe Sizes from the data set below?
oksano4ka [1.4K]

Answer:

10

Step-by-step explanation:

Hi!

We first need to order the numbers in the sequence in ascending order:

6.5,\:7,\:7.5,\:9,\:9,\:10,\:11,\:12.5,\:13,\:13,\:13

<em>The median is the middlemost number(s) in a sequence.</em>

<em />

In that case, we can see that \boxed{\boxed{10}} is the median.

More info:

Since there are 11 terms, we will divide by two. 11 ÷ 2 = 5.5. Since we round up from 5, we will count over 6 terms.

In doing so, we can see that 10 will remain our answer.

Hope this helps!
