What is the area of the shaded part of the figure? A.
112.5 mm²
B.
225 mm²
C.
450 mm²
D.
675 mm²
Answers
Answer 1
Answer:
Area of triangle= (h*b)/2 = (30*30)/2 = 450
Area of the square unshaded = (a*a) = (15*15) = 225
Area of shaded part = 450-225 = 225
Area of the square unshaded = (a*a) = (15*15) = 225
Area of shaded part = 450-225 = 225

We simplify 10q-13-5q=12 to 5q-13=12. Now, we add 13 to both sides, 5q-13+13=12+13. We should get 5q=25. Finnally, we divide both sides by 5, 5q/5=25/5, Therefore, the answer is q=5

y (y) less than (minus) 21 (21
y-21
y-21
21-y
This is because it says "less than" which is a way to say subtraction. So if you want y less than 21 it would be written as 21-y.

90 • 4 – 14 ÷ 2 + 10² ÷ 5 • 2
Answers
90 x 4 - 14 / 2 + 10^2 / 5 x 2
For this expression, you would use the method PEMDAS.
(Parentheses Exponents Multiplication Division Addition Subtraction)
The first one available in this expression is Exponents (10^2=100)
90 x 4 - 14 / 2 + 100 / 5 x 2
Then Multiplication (90 x 4 = 360 and 5 x 2= 10)
360 - 14 / 2 + 100 / 10
Next is Division (14 / 2 = 7 and 100 / 10 = 10)
360 - 7 + 10
Now Addition or Subtraction (whichever one is first from left to right)
353 + 10
90 x 4 - 14 / 2 + 10^2 / 5 x 2 = 363
