Answer:

25 minutes

Step-by-step explanation:

Think about how many steps per minute Paul can walk. Knowing that he can walk 15 steps in 5 minutes, we can say that Paul can walk 3 steps/minute.

We're asked to figure out how many minutes it would take him if he walks at a constant speed if he takes 75 steps. So we can just divide 75 steps into 3 steps/minute and then we should get 25 minutes!

Answer:

25 Minutes.

15.25-8.50= 6.75, 6.75÷.75=9

Answer:

9 fountain drinks

Step-by-step explanation:

8.50+0.75x=15.25 is the equation you will use. 8so is your starting point and for every drink you get, it is 75 cents.

Solve by subtracting 8.50 from 15.25

0.75x=6.75

Divide 6.75/0.75 to isolate the x.

x=9

Question is incomplete :

It costs $4 to go to the swimming pool

The cost of n visits =

Membership at the pool costs $21. Members pay $3 each time. WHAT is The cost for a member to swim including membership fee?

What is the difference between the cost of 15 visits with and without a membership?

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Swimming cost = $4

Cost of swimming n Times = cost per swim * number of swims

= $4 * n

= $4n

Membership cost = $21

Cost per swim for members = $3

Swimming cost including membership fee :

21 + 3n ; n = number of visits

For 15 visits ; n = 15

Amount paid :

Members = 21 + 3(15) = 21 + 45 = $66

Non - Member = 4(15) = 60

Difference :

$66 - 60 = 6

Members incur $6 more than non - members

There are 360 cubic inches of cheese would you have eaten.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

This wedge of cheese is shaped like a triangular prism.

And, The wedge of cheese is 10 inches tall. The base of the cheese is shaped like a triangle with a base of 9 and a height of 8 inches.

Hence, The value of volume of cheese is,

⇒ (1/2 × 9 × 8) × 10

⇒ 36 × 10

⇒ 360 inches³

Thus, There are 360 cubic inches of cheese would you have eaten.

Answer:

Step-by-step explanation:

Answer:

A. 6

Step-by-step explanation:

6.16441400297

This rounds to 6.

Answer:

(1, 6) is the solution

Step-by-step explanation:

-2x + 6y = 34

2x + 2y = 14;     divide by 2

x + y = 7;        subtract x

y = 7 - x

let's substitute y with 7 - x in first equation

-2x + 6*(7 - x) = 34;    expand multiplication

-2x + 6*7 - 6*x = 34;    group

-8x + 42 = 34;         subtract 42

-8x = 34 - 42 = -8;      divide by -8

x = 1

y = 7 - 1 = 6

It is the only solution, as we've arrived at exact numbers.

Answer:

12 nickels

11 dimes

Step-by-step explanation:

Let n = no. of nickels

     d = no. of dimes

   5n = value of nickels in cents

   10d = value of dimes in cents

    170 = total value in cents

(1)   n + d = 23             (2)   5n + 10d = 170

           d = 23 - n                5n + 10(23 - n) = 170

                                           5n + 230 - 10n = 170

                                                     - 5n = - 60

                                                          n = 12 nickels

           d = 23 - 12 = 11 dimes

Check:  12(5) + 11(10) = 60 + 110 = 170 cents or $1.70

Answer:

[tex]AB = 5[/tex]

Step-by-step explanation:

Given

[tex]A =(1,-1)[/tex]

[tex]B = (1,4)[/tex]

[tex]C = (8,4)[/tex]

Required

Distance between vertices A and B

To do this, we simply calculate distance AB using distance formula.

[tex]d = \sqrt{(x_1-x_2)^2 + (y_1 - y_2)^2}[/tex]

So, we have:

[tex]AB = \sqrt{(1-1)^2 + (4 - -1)^2}[/tex]

Simplify the expression the bracket

[tex]AB = \sqrt{0^2 + 5^2}[/tex]

Evaluate all squares

[tex]AB = \sqrt{0 + 25}[/tex]

[tex]AB = \sqrt{25}[/tex]

Take positive square root

[tex]AB = 5[/tex]

Hence, the line segment that connects A and B is 5 units long.

Answer:

[tex] x = 45 \ \& \ y = 5 [/tex]

Step-by-step explanation:

The system of linear equations in two variables is ,

[tex]\begin{cases} x = 9y \cdots (i)\\ x - 5y = 20\cdots (ii) \end{cases}[/tex]

We can easily solve out this Question using substitution method . For that , substituting x = 9y from equation (i) to equation (ii) , we have ,

[tex]\implies x - 5y = 20 \\\\\implies 9y - 5y = 20 \\\\\implies 4y = 20 \\\\\implies y =\dfrac{20}{4}\\\\\implies\boxed{\boxed{ y = 5 }}[/tex]

Substituting this value in (i) ,

[tex]\implies x = 9y \\\\\implies x = 9\times 5 \\\\\implies \boxed{\boxed{ x = 45 }}[/tex]

Answer: (45,5)

Step-by-step explanation:

You're given what x equals: 9y. Substitute that into the equation x - 5y = 20. Your equation should look like this: 9y - 5y = 20. From there, solve for y. 9y subtracted by 5y is 4y. Then, solve 4y = 20. Divide both sides of the equation by 4. The result is y = 5. We now know the y-coordinate in the ordered pair. Substitute this y-value into the first equation: x = 9y. 9(5) = 45. x = 45.

Plug these two values into the ordered pair (x,y).

sorry if im wrong its been awhile since ive done this

Answer:

Step-by-step explanation:

One clue about where to start is this: the sentence describes the length by referring to the width. "The LENGTH is blah, blah, blah, the WIDTH. When that happens, choose a variable to represent the width (the quantity being referred to).

Width = w

Length IS three more than (added to) 4 times (multiplied by) the width

Length = 4w + 3

Area of a rectangle is the width multiplied by the length.

Equation: w(4w + 3) = 24

Solve.

Multiply out the left side.

4w^2 + 3w = 24

Subtract 24.

4w^2 + 3w -24 =0

This equation does not factor. Use the Quadratic Formula. One of the solutions is a negative number, so that should be rejected (width can't be a negative number).

[tex]w=\frac{-3+\sqrt{393}}{8}[/tex]

Substitute this into the expression 4w + 3 to find the length. A calculator can give you decimals for both dimensions.

Answer:

18 t-shirts.

Step-by-step explanation:

Trey made a total profit $106 by selling t-shirts and hats. $34 of that profit was from selling hats, subtract 34 from 106 and you will get 72. So he made a profit of $72 in selling t-shirts. The t-shirts were $4 each, so if you divide 72 by 4 you will get 18. Meaning he sold 18 shirts.

Answer:

C(t) = 0.55t + 7.75, $30.85

Step-by-step explanation:

the fixed cost is $7.75. this is the cost incurred at zero minutes of the taxi ride

the variable cost or the cost per minutes driven =

(13.25 - 7.77) / (10 - 0) = 0.55

total cost = 7.75 + 0.55t

cost of 42 minutes = 7.75 + 0.55(42) = $30.85

Answer:

first, x and x that will be 2x  then x and 5 in the green box u get 5x and then pink you get 4x and orange you get 20.

Step-by-step explanation:

The required value of the missing sides with the help of trig ratios we have x = 19.9.

If you know the lengths of two sides of a right triangle, you can use trigonometric ratios to calculate the measures of one (or both) of the acute angles.

Here,
To find the missing side in the given right triangle, we can use trigonometric ratios. Specifically, we can use the tangent ratio:

Cosine of an angle = opposite side / adjacent side

In this case, we know the measure of one acute angle (19 degrees) and the length of the adjacent side (21). We want to find the length of the opposite side, which we can represent as x.

cos(19°) = x / 21

Multiplying both sides by 21, we get:

x = 21 cos(19°)

Using a calculator, we can evaluate the right-hand side to get:

x ≈ 19.85

Rounding to the nearest tenth, the missing side is approximately 19.9 units long.
