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:
xy=wz

Answer:
13×11=143cm[tex]{2}[/tex]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

What is the value of z? Please provide an explanation, thanks!
Answer:
z=7
Step-by-step explanation:
72°+(8z-8)°+(9z-3)°=180° (a triangle contains 180° and vertical angles are equal)
(8z-8)°+(9z-3)°=180°-72°
17z°-11°=108°
17z°=108°+11°
17z°=119°
z°=119°/17°
z°=7°
z=7
Find the slope of the line that contains (-9, 1) and (3,6).
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.

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

When writing the coordinates does it matter if we put x or y first?
Answer:
hii
Step-by-step explanation:
yes it does matter the The x-coordinate always comes first, followed by the y-coordinate.
Answer:To locate (2,5), move 2 units to the right on the x-axis and 5 units up on the y-axis. The order in which you write x- and y-coordinates in an ordered pair is very important. The x-coordinate always comes first, followed by the y-coordinate.

Rameez borrowed Rs. 20,000 from a bank at the rate 5% p.a compounded annually. What amount will he pay at the end of three years to clear the loan?
Answer:
23000
Step-by-step explanation:
If you multiply 20,000 * 0.05 (the percentage of the rate) you get 1000
This means that for 3 years he will pay an interest of 3000, plus the original loan 20000 which means he will pay 23000 :D

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 )
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.

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?
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
