Give answer in cm squared
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

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

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.
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
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.

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

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

Johnny says that 600 cm is not enough moulding for the baseboards that measure 5642 mm. Is he right in his statement? Explain
Answer:
Johnny is wrong.
Step-by-step explanation:
To compare two quantities, they must both be written in the same units. In this case, both must be in centimeters or millimeters. So, we must convert 600cm to millimeters or vice versa.
If we choose to use milimeters, we have
600cm=600cm [tex]\frac{10mm}{1cm}[/tex]
600cm = (600)(10) mm
600cm = 6000 mm
Now, we must compare 6000 mm with 5642 mm. We can see that 6000mm is greater than 5642 mm. hence, it is enough moulding for the baseboards.
In fact, 6000-5642 mm =358 mm would remain.
