Answer:
Step-by-step explanation:
Given
From Figure
Sides of Triangle
Now, using concept
Perimeter of triangle = Sum of the sides of triangle
So,
Perimeter of triangle = 
Adding 
and 
, so,
Perimeter of triangle = 
This can be written as
Perimeter of triangle =
Adding 15 and 10,
Perimeter of triangle =
So, the correct choice is =

Answer:
4
Step-by-step explanation:
Let y be the width of the rectangle
The length of the rectangle is 5 unit more than the width. This is written as:
Length = y + 5
Area = 36
Recall:
Area of rectangle = length x width
36 = (y + 5) x y
36 = y^2 + 5y
Rearrange the expression
y^2 + 5y — 36 = 0
To solve this problem by factorization, multiply the first term (i.e y^2) and last term ( i.e — 36) together. This gives — 36y^2
Next, find two factors of —36y^2 such that when we add them together it will result to the second term (5y). These factors are —4y and 9y. Now we substitute —4y and 9y in place of 5y in the equation. This is illustrated below:
y^2 + 5y — 36 = 0
y^2 —4y + 9y — 36 = 0
We factorize as follows:
y(y — 4) + 9(y —4) = 0
(y + 9) (y — 4) =0
y + 9 = 0 or y — 4 = 0
y = —9 or y = 4
Since the measurement can not be negative, therefore y (i.e the width) is 4
Answer:
22°
Step-by-step explanation:
If the mean is m and the standard deviation is s, then we can say that the temperatures that fall <em><u>within 1 standard deviation of the mean</u></em> will be:
m - s < temperatures < m + s
To we take the sum of mean and standard deviation: 24 + 4 = 28
and, the different of mean and standard deviation: 24 - 4 = 20
So, <em>the temperature that is in between 20 and 28 is the temperature within 1 standard deviation of the mean</em>.
This is the third answer, 22°
