The value of the distance is 165 m and the value of the distance is 55x

<h3>How to determine the values of the variables?</h3>

The formula is given as:

d =rt

<u>a. You traveled 3 hours at 55 mph</u>

This means that

r = 55 and t = 3

So, we have:

d = rt

This gives

d = 55 * 3

Evaluate

d = 165

Hence, the value of the distance is 165 m

<h3>b. You traveled x hours at 55 mph. = ____</h3>

This means that

r = 55 and t = x

So, we have:

d = rt

This gives

d = 55 * x

Evaluate

d = 55x

Hence, the value of the distance is 55x

Tony needs to create a platform shaped like the diagram with the labeled dimensions.
konstantin123 [22]
<h2>135 cubic feet of concrete are required to create the platform.</h2>

Step-by-step explanation:

The dimension of lower step is 6 ft× 3 ft× 1.5 ft

and the dimension of upper step is 6 ft ×(9-3)ft × (1.5+1.5)ft = 6 ft × 6 ft ×3 ft

Therefore concrete are required to make lower step = (6×3×1.5) cubic feet

                                                                                       = 27 cubic feet

and concrete are required to make upper step = (6×6×3) cubic feet

                                                                               =108 cubic feet

<h3>∴(108+27) cubic feet = 135 cubic feet of concrete are required.</h3>

Arthur has decided to start saving for a new computer. His money is currently in a piggy bank at home, modeled by the function s
Leya [2.2K]

Two or more independent functions (say f(x) and g(x)) can be combined to generate a new function (say g(x)) using any of the following approach.

h(x) = f(x) + g(x)         h(x) = f(x) - g(x)

h(x) = \frac{f(x)}{g(x)}                   h(x) = f(g(x))

And many more.

The approach or formula to use depends on the question.

In this case, the combined function is:

f(x) = 75+ 10x

The savings function is given as

s(x) = 85

The allowance function is given as:

a(x) = 10(x - 1)

The new function that combined his savings and his allowances is calculated as:

f(x) = s(x) + a(x)

Substitute values for s(x) and a(x)

f(x) = 85 + 10(x - 1)

Open bracket

f(x) = 85 + 10x - 10

Collect like terms

f(x) = 85  - 10+ 10x

f(x) = 75+ 10x

A hat contains pieces of paper marked with the numbers 1 through 16. Tell whether picking an even number is impossible, unlikely
Anna [14]

Answer:

Picking an even number is an as likely event and it's probability is 1/2

Step-by-step explanation:

We know that the numbers present are 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16

The odd numbers are 1,3,5,7,9,11,13,15

The even numbers are 2,4,6,8,10,12,14,16

There are 8 even numbers and 8 odd numbers.

And also if we pick a number it should be either an even number or an odd number.

Probability(Getting an even number) = \frac{even number}{even number+oddnumber}

Probability = \frac{8}{8+8} = 1/2

Therefore picking an even number is an as likely event and it's probability is 1/2
