Answer:
A = 44 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
We require to find the missing segment of b₁
Using the tangent ratio in the right triangle
tan45° = =
= 1 , so
adjacent = 4
Then
b₁ = 4 + 8 + 2 = 14 , b₂ = 8 and h = 4 , then
A = × 4 × (14 + 8) = 2 × 22 = 44 cm²

Answer:
x=24
Step-by-step explanation:
The Quotient(dividing) of a number(x) and 6 minus(-) 3 IS(=) 1.
Which turns into:
- 3 = 1
We want to get x by itself so we divide the entire equation by 6.
6 ( - 3 = 1 )
x - 18 = 6
We want to move the plain numbers to one side so x can be by itself. So we add 18 to both sides.
x = 24
Answer: For every 1 can of red paint, the number of yellow paints used by the painter is and
There are approximately 29 cans of yellow paints for 34 cans of red paints.
Step-by-step explanation:
Since we have given that
Number of cans of red paint = 14
Number of cans of yellow paint = 12
According to question, we have to find that for every 1 can of red paint the painter uses what number of yellow paints;
Since the ratio of red paint to yellow paint is given by
So, for every 1 can of red paint, the number of yellow paints used by the painter is
Similarly,
If Number of can of red paint is used = 34
So, Number of cans of yellow paint will be
Hence, there are approximately 29 cans of yellow paints for 34 cans of red paints.
