What is the volume of this rectangular prism?

Answers

Answer:

1cm³

Step-by-step explanation:

You do not need a calculator for this.

The formula for the volume of a rectangular prism is:

Length × Width × Height = Volume

If we substitute our numbers in:

5/4 × 4/3 × 3/5 = 1cm³

All you need to do is multiply across.

5 × 4 × 3 = 60

4 × 3 × 5 = 60

The numerator and denominator both equal 60. So the fraction would look like this if you were to keep it as a fraction.

60/60

C (X) =0.09x +9.75

What is the total rental cost if Lashonda drove 30 miles?



need major help pleaseee this is functions

Answers

Answer:

$12.45

Step-by-step explanation:

To find the rental cost, plug in 30 as x

c(x) = 0.09x + 9.75

c(30) = 0.09(30) + 9.75

c(30) = 12.45

So, the total rental cost for 30 miles is $12.45

Cindy has -$40 in her bank account. She earns $100 babysitting so she deposited it into her account. She then withdrew $50. How much does her bank account have now?

Answers

Answer:

$10

Step-by-step explanation:

Let's take this step by step. First, we know that Cindy has -$40 in her bank account. She then adds the $100 she earned, so we add -40 and 100:

-40 + 100 is the same as 100 - 40, which is 60. So, Cindy now has $60 in her bank account. Next, she took out $50. We must subtract that from what she has from her bank account:

60 - 50 = 10

Therefore, Cindy has $10 in her bank account now.

Hope this helps :)

Find g(x), where g(x) is the translation 7 units right of f(x)=x2. Write your answer in the form a(x–h)2+k, where a, h, and k are integers.

Answers

Answer:

[tex]g(x) =1(x + 7)^2 + 0[/tex]

Step-by-step explanation:

Given

[tex]f(x) = x^2[/tex]

Required

Determine g(x) where g(x) is a translation of f(x), 7 units to the right

When a point is translated to the right, the resulting point is:

[tex]x -> x + b[/tex]

Where b is the number of units to the right.

In this case:

[tex]b = 7[/tex]

So, we have:

[tex]g(x) = f(x +7)[/tex]

Solving f(x+7)

Substitute x + 7 for x in [tex]f(x) = x^2[/tex]

[tex]f(x + 7) = (x+7)^2[/tex]

So, we have:

[tex]g(x) = (x+7)^2[/tex]

To write in the form of [tex]a(x - h)^2 + k[/tex], we have:

[tex]g(x) =1(x + 7)^2 + 0[/tex]

A stadium had a total of 19,000 seats. Of these seats 5,500 are field seats, and the rest are grandstand seats. Complete an equation that could be used to find s, the number of grandstand seats

Answers

Answer: The equation to find  Number of grand seats, s are either of the following

               x+ s= Total seats

                x+s= 19,000

                5000+s= 19,000

Number of grand seats, s= 14,000

Step-by-step explanation:

Step 1

A stadium had a total of 19,000 seats.

Given that  field seats=5,500

And the rest which are grandstand seats=?

Let field seats be represented  as x and grand seats be represented as s

such that the total  number of seats can be expressed as

x+ s = Total seats

x+ s=  19,000-------- Equation.

5000+s= 19,000

Step 2

Such that given field seats, x= 5000, Number of grand seats will  now be

x + s= 19,000

5000 + s= 19,000

s= 19,000-5000

=14,000 seats

I’m assuming you need to find the equation of the line?

Equation of line is written in the form y=mx+c where m is the slope and c is the y-intercept.

We know the slope is -4, so we have y=-4x+c.

To find c, we replace the given coordinates in the equation:

4=-4(-5)+c
4=20+c
c=-16

So, the equation of the line is

y = -4x -16
