Answer:
28
Step-by-step explanation:
12+[(15-5)]+(9-3)]
PEMDAS
Parentheses first
12+[(10)]+(6)]
Then add
12+10+6
70.4
The word "of" means to multiply, so 22% or .22 * 320 = 70.4
Answer:
h = 5.5
Step-by-step explanation:
2.3 + h = 7.8
-2.3 -2.3
h = 5. 5
Answer:
A. and C.
Step-by-step explanation:
We don't know the area of the roof or the number of people in the group so they would both be represented by variables in an equation.
Answer:
C. The sum of the areas of the two smaller squares is equal to the area of the larger square.
Step-by-step explanation:
9 + 16 = 25
36 + 64 = 100
25 + 144 = 169
The relations "less than" and "greater than" can be ruled out. These observations are consistent with selection C.
The triangle area is half the product of the square roots of the squares on the legs, so the areas of the triangles are (respectively) 6, 24, 30. These are not related to the sum of the smaller squares, so the last selection can also be ruled out.
