Answer: 21. Perimeter = 48 22 . Perimeter= 36 23. Perimeter= 72
Step-by-step explanation:
First you need to find the side length using the area of each of the squares. We know that to find the area of a square you will have to square one of the side lengths, that means that to find the side length, we will need to find the square root of the area.
21 . Find the square root of 144.
[tex]\sqrt{144}[/tex] = 12
The side length is 12 so multiply it by 4 to find the perimeter because the perimeter is the distance around the shape. All the side length's of a square are the same and there four sides so multiply it by 4 to find the perimeter.
Perimeter = 12 * 4
Perimeter = 48
22. The same thing with this one, find the square root and multiply the side length by 4.
[tex]\sqrt{81}[/tex] = 9
Perimeter = 9 *4
Perimeter = 36
23. [tex]\sqrt{324}[/tex] = 18
Perimeter = 18 * 4
Perimeter = 72

Answer:
Step-by-step explanation:
5x+9y=-3 Multiply both sides by 8
40x+72y=-24
-53x-8y=-3 Multiply both sides by 9
-477x -72y= -27
sum the equations vertically to eliminate one variable
40x+72y= -24
-477x-72y= -27 (the y cancels out )
-477x =-51 (-24 + -27=-51)
-477x=-51 / -477 divide both sides by -477
x =51/437
5x 51/437=9y= -3 substitute the value of x
y= -174 /437
(x,y) = (51/437, -174/437)

maria spent 4/7 of money on books,1/5 of it on a pen and 1/14 of it on a newspaper. She has left 220 naira. How much did she originally have?
Answers
3/7 + 1/4 + 1/8 = 45/56
She spend 45/56 of x.
∴ 45/56 × x = (45/56)x
1 - 45/56 = 11/56
(11/56)x is the money that was left.
This is equivalent to 11.
(11/56)x = 11
11x = 11×56
11x = 616
x = 616/11
= 56.

Answer:
y = 2x + 4
Step-by-step explanation:
You have the graph, so you can read the slope and y-intercept from it. The line goes up 2 units for each unit to the right, so the slope is ...
slope = rise/run = 2/1 = 2
The y-intercept is where the graph crosses the y-axis, at y=4.
The slope-intercept form of the equation for a line is ...
y = mx + b
where m is the slope (2) and b is the y-intercept (4). Your equation is ...
y = 2x +4

The total area of the polygon is 176 square feet. Find the value of x. x= ft
Answers
Answer:
x = 6 ft
Step-by-step explanation:
Area of the polygon = area of the square + 2(area of the triangle)
Area of the polygon = 176 ft²
Area of the square = length × width = 16 × 8 = 128
Area of the two triangles = 2(½*base*height) 2(½*x*8) = 8x
Plug in the above values into the equation for area of the polygon. Thus:
176 = 128 + 8x
Subtract 128 from each side
176 - 128 = 8x
48 = 8x
Divide both sides by 8
6 = x
x = 6 ft
Answer:
x=6ft

A mountain road rises 10 feet over a 206-foot run. What is its slope?
Answers
It's slope is 5/103 , by using simple calculation for slope.
What is slope?
In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. The letter m is frequently used to represent slope; the reason for this usage is unclear, but it can be found in O'Brien's (1844) and Todhunter's (1888) formulations of the equation for a straight line as "y = mx + b" and "y = mx + c," respectively. The ratio of the "vertical change" to the "horizontal change" among (any) two distinct points along a line is used to calculate slope. The ratio can also be written as a quotient (also known as "rise over run"), which gives the same number for each and every two distinct points on same line.
Mathematically, it's calculated as "rise over run".
Here,
Rise is given i.e. 10feet.
and foot-run=206.
So, slope = Rise/foot-run
= 10/206
= 5/103 .
Hence, slope = 5/103.

How many factors of 100 are also multiples of 5?
Answers
Let us write the factors of 100. A factor of 100 can only be a multiple of five if it is divisible by five.
Divisibility rule of 5: A number can only be divisible by five if the ones digit of the number is a five or 0.Factors of 100 ⇒ numbers divisible by 100 ⇒ 1, 2, 4, 5, 10, 20, 25, 50, 100
When checking each factor of 100;
1 is not a multiple of 5 ⇔ not divisible by 5.2 is not a multiple of 5 ⇔ not divisible by 5.4 is not a multiple of 5 ⇔ not divisible by 5.5 is a multiple of 5 ⇔ divisible by 5.10 is a multiple of 5 ⇔ divisible by 5.20 is a multiple of 5 ⇔ divisible by 5.50 is a multiple of 5 ⇔ divisible by 5.100 is a multiple of 5 ⇔ divisible by 5.⇒ Five factors are multiples of 5.
Therefore, five factors of 100 are multiples of 5.
