Answer:
PEMDAS Answer:A
Step-by-step explanation:
parentheses exponents multiplication division addition and subtraction in order
0.674 means that it 674/1000
which mean that if the model consists of 1000 squares, you have to shade 674 of the squares.
If the model consists of 500 squares, you have to shade 337 of the squares ( you get the number after dividing both 674 and 1000 with 2)
Answer:
2700 because
Step-by-step explanation:
I multiplied 900 by 3
Answer:
3/2 or 1 1/2 or 1.5
Step-by-step explanation:
first do the equations in each parentheses:
(-5+2) = -3
(-1/2) = -1/2
then multiply both sides:
-3 • -1/2 (which is the same as -3 • -1 over 2)
= 3/2 or 1 1/2 or 1.5
Answer:
P = 28cm
Step-by-step explanation:
The general formula for the perimeter of a rectangle is: 'P = 2L +2W' (L being the length and W being the width of the rectangle.)
Step 1: Substitute L = 7, W = 7 into the general formula.
P = 2(7) + 2(7)
Step 2: Solve!
P = 2 x 7 + 2 x 7
P = 14 + 14
P = 28
Step 3: Don't forget to add the units of measurement! (In this case 'cm')
Therefore, P = 28cm
