a cab company charge s a flat rate of $2 plus and additional $0.50 for every mile traveled when Sara arrived at her destination her cab fare $7.50 write and solve and equation to determine how many miles sara traveled

Answers

Answer 1
s+0.50m=7.50
2+0.50m=7.50
subtract from both sides
(2-2)+0.50m=7.50-2
0.50m=5.50
0.50m/0.50=5.50/0.50
divide 0.50 from both sides
m=11
Sarah traveled 11 miles.

You are choosing between two different cell phone plans. The first plan charges a rate of 22 cents per minute. The second plan charges a monthly fee of $34.95 plus 8 cents per minute. Let t be the number of minutes you talk and C1 and C2 be the costs (in dollars) of the first and second plans. Give an equation for each in terms of t, and then find the number of talk minutes that would produce the same cost for both plans (Round your answer to one decimal place). C1= C2= If you talk for minutes the two plans will have the same cost.

Answers

Answer:

249.64285714 minutes

Step-by-step explanation:

Let

The number of minutes you talk = t

C1 = Cost in dollars of the first plan

C2 = Cost in dollars of the second plan

First plan

The first plan charges a rate of 22 cents per minute

Converting cents to dollars

100 cents = 1 dollars

22 cents =

22/100 cents

=$ 0.22

C1 = $0.22 × t

C1 = 0.22t

Second Plan

The second plan charges a monthly fee of $34.95 plus 8 cents per minute.

Converting cents to dollars

100 cents = 1 dollars

8 cents =

8/100 cents

=$ 0.08

C2 = $34.95 + 0.08t

Find the number of talk minutes that would produce the same cost for both plans

We would Equate C1 to C2

C1 = C2

0.22t = $34.95 + 0.08t

Collect like terms

0.22t - 0.08t = $34.95

= 0.14t = $34.95

Divide both sides by 0.14

= t = $34.95/0.14

t = 249.64285714

Therefore, the number of talk minutes that would produce the same cost for both plans is 249.64285714 minutes.

what is a two variable linear equation

Answers

Answer: Linear equations in two variables. If a, b, and r are real numbers (and if a and b are not both equal to 0) then ax+by = r is called a linear equation in two variables. (The “two variables” are the x and the y.) The numbers a and b are called the coefficients of the equation ax+by = r.

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

It's an equation that has two variables

that's to say it has x and y (generally)

it is linear when you graph it, it forms a line and that only happens when the mayor exponent is one

so

[tex](something_1)x^{1}+(something_2)y^{1} =(something_3)[/tex]

notice all the something are completely different

or you could find it as

[tex]y=mx+b[/tex]

where m is the slope

and b some number

so that's it

$15.95. Josh paid a total of $135.95 to the fitness center for boxing classes and a set of gloves.
How many boxing classes did Josh attend?

Answers

Answer:

8

Step-by-step explanation:

total paid: $135.95

cost of gloves: $15.95

amount for classes: $135.95 - $15.95 = $120

cost of each class: $15

number of classes: $120/$15 = 8

Answer: 8 classes

In the answer space below, provide one of the two positive integers whose product is 196 and whose sum is a minimum.

Answers

Answer:

14

Step-by-step explanation:

The value of two positive integers are 14 and 14.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Product of two positive integers are 196.

Sum of two positive integers are minimum.

Now,

Let two positive integers are x and y.

Since, Product of two positive integers are 196.

So, we can formulate;

xy = 196    ... (i)

And, Sum of two positive integers are minimum.

So, we can formulate;

s = x + y

From equation (i);

y = 196/x

Substitute in above equation, we get;

s = x + y

s = x + 196/x

Differentiate with respect to x as;

d/dx (s) = d/dx(x + 196/x)

ds/dx = 1 - 196/x² ... (ii)

Substitute ds/dx = 0, we get;

ds/dx = 1 - 196/x² = 0

1 - 196/x² = 0

1 = 196/x²

x² = 196

x = ± 14

Differentiate equation (ii) again;

d²s/dx² = 0 - (-2 × 196)/x³

d²s/dx² = 392/x³

At point x = 14,

d²s/dx² = 392/8³ > 0

Hence, At x = 14, the value is minimum.

So, we get;

xy = 196

at x = 14

y = 196/14

y = 14

Hence, The value of two positive integers are 14 and 14.

The size of a playground is 160 feet by 360 feet. A model is created that measures 4 inches by 9 inches. Is it a rate, ratio only or a proportion?

Answers

Answer:

The model is made in a 1:40 ratio

Step-by-step explanation:

How many times is 4 multiplied to be equal to 160?

4(x) = 160

X = 160 / 4

X = 40

The proportion, rate, and ratio are almost the same.

They represent the correspondence between the parts and the whole since they all express a binary relationship between the quantities, that is, objects, people, tablespoons.

If the ratio is 1: 2 it could be read that for every 1 there are 2.

For example 1: 2 cups; For every cup of something there are 2 cups of something else.

In this case, 1:40; For every inch of the model, there are 40 feet in the playground.

perimeter of Central Park? Show your work,

Answers

Answer:

6

Step-by-step explanation:

Given that the coordinate plane, three of the vertices of the rectangle are located at (-1.25, -0.25),

(-1.25, 0.25), and (1.25, 0.25)

The length L of the shape will be:

L = 0.25 - ( - 0.25 )

L = 0.25 + 0.25

L = 0.5

The width of the shape will be:

W = 1.25 - ( - 1.25)

W = 1.25 + 1.25

W = 2.5

Perimeter P = 2L + 2W

Substitute the Length and the width into the formula

P = 2(0.5) + 2(2.5)

P = 1 + 5

P = 6 metres

Therefore, the perimeter of the shape is 6 metres
