Answer:
Step-by-step explanation:
This question is about the benefits of estimation.
1300/13 is easy and results in 100.
1287/13 can be approximated by 1300/13: 1287/13 ≈ 100.
Actually, 1287 = 1300 - 13 = 13(99); just subtract 1 from 100.
So: 1287/13 = 1300 - 13 = 1287. A nice bit of mental math!
Step-by-step explanation:
amount increased to the toy = y
new price of the toy after adding markup = z
y= ( ( 25/100) × X )
therefore z= x+y
When the base and the height of a triangle are the same. the hypotenuse is that number times sqrt2.
B and C are 7, so a would also be 7
46%, .455, .45, 44.9%, 44.5%
Answer:
-7
Step-by-step explanation:
(7 4/9 −8)∙3.6–1.6∙( 1/8 − 3/4 )+1 2/5 ÷(−0.35)
PEMDAS, parenthesis
-5/9∙3.6–1.6∙(1/8-6/8)+1 2/5 ÷(−0.35)
PEMDAS, division
-5/9∙3.6–1.6∙-5/8-4
PEMDAS, multiplication
-5/9∙ 18/5– 8/5 ∙-5/8-4
-2-1-4
PEMDAS, subtraction
-7
