Wilmer went up a hill for x minutes at a speed of y kilometers per minutes. Then he went down the same path at a speed of z kilometers per minute, and it took him w minutes to do it. Write an equation that relates x, y, z, and w. (The wording for this question really confuses me. And I do not understand which variable to put on it's own.) PLEASE ANSWER

Answers

Answer 1

Answer:

[tex]xy=wz[/tex]

Step-by-step explanation:

Given that:

Speed of Wilmer up the hill = [tex]y[/tex] km/min

Time taken up the hill = [tex]x[/tex] minutes

Speed of Wilmer down the hill = [tex]z[/tex]  km/min

Time taken up the hill = [tex]w[/tex] minutes

Distance can be calculated by multiplying the Speed with Time i.e.

The formula for distance is given as:

[tex]Distance = Speed \times Time[/tex]

Distance up the hill = [tex]y\times x =xy\ kilometers[/tex]

Distance down the hill = [tex]z\times w =wz\ kilometers[/tex]

It is well known that, the distance up the hill and down the hill will be same.

Putting both the values equal, we get:

[tex]xy=wz[/tex]

Answer 2

Answer:

xy=wz

Step-by-step explanation:

you do base times height

Answer:

110.5 cm²

Step-by-step explanation:

The figure is composed of a rectangle with a triangle on top.

Area of rectangle = 13 × 6 = 78 cm²

Area of triangle = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

Here b = 13 and h = 11 - 6 = 5 cm , then

A = [tex]\frac{1}{2}[/tex] × 13 × 5 = 32.5 cm°

Thus

total area = 78 + 32.5 = 110.5 cm²

The wholesale cost of a pair of sandals at a shoe store is $22.60. The markup for the sandals is 45%. What is the selling price of the sandals?

Answers

Answer:

The selling price of sandals is: $32.77

Step-by-step explanation:

Mark up is the price that is added to the cost price of a product for profit.

Given

Price of sandals = $22.60

Mark up = 45%

To find the price with mark up, we will find the amount of mark up and then add it to the cost price of sandals.

[tex]Mark\ up = 45\%\ of\ 22.60\\= 0.45*22.60\\=10.17[/tex]

The mark up is $10.17

Now,

[tex]Selling\ price = Cost + mark\ up\\= 22.60+10.17\\=32.77[/tex]

Hence,

The selling price of sandals is: $32.77

(8z-8)°+(9z-3)°=180°-72°

17z°-11°=108°

17z°=108°+11°

17z°=119°

z°=119°/17°

Find the gradient of the line segment between the points (-8,6) and (4,7).
Give your answer in its simplest form.

Answers

Answer:

Step-by-step explanation:

Gradient or slope = (7-6)/(4-(-8))

= 1/12

The gradient of a line is the same as the slope of the line.

The gradient of the line segment between the points (-8,6) and (4,7) is 1/12

The points are given as:

[tex](x,y) = \{(-8,6),(4,7)\}[/tex]

The gradient (m) of a line segment is:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

So, we have:

[tex]m = \frac{7-6}{4-(-8)}[/tex]

[tex]m = \frac{7-6}{4+8}[/tex]

[tex]m = \frac{1}{12}[/tex]

Hence, the gradient of the line segment is 1/12

Sonia wanted to purchase a raincoat that cost 12.00 if there would be an 8% sales tax for the purchase ,how much would the sales tax be (round your answer to the nearest cent )

Answers

Answer:

i thing is 1

Step-by-step explanation:

Answer:

$1

Step-by-step explanation:

In order to get the sales tax, you have to perform the multiplication operation by multiplying $12 by 8%.

Let x be the sales tax.

x = $12 x 8%

x = 12 x 0.08

x = 0.96

To round off the answer to the nearest cent, you have to look for the last number in the cents' place. If the number is 5 or above, you have to add 1 to the number next to it. If it's below 5, you just have to copy the values.

In the case above, the last number in the cents' place is 6. This is above 5, so we have to add 1 to 9, which will make it 100 cents or $1.

So, the sales tax is $1.

Find the slope of the line that contains (-9, 1) and (3,6).

Answers

Answer:

The slope is 5/12

Step-by-step explanation:

To find the slope between any two points, we can use the slope formula:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Where (x₁, y₁) and (x₂, y₂) are our two points.

We have the two points (-9, 1) and (3, 6).

Let’s let (-9, 1) be (x₁, y₁) and let (3, 6) be (x₂, y₂). Substitute appropriately:

[tex]\displaystyle m=\frac{6-1}{3-(-9)}[/tex]

Evaluate:

[tex]\displaystyle m=\frac{5}{12}[/tex]

So, the slope of the line that contains the two points (-9, 1) and (3, 6) is 5/12.
