Answer:
Thus, the value of expression is .
Step-by-step explanation:
Given : 3 + (2 + 8)power 2 ÷ 4 × 1 over 2 to the power of 4
Mathematically written as
We apply BODMAS,
Where ,
B stands for brackets
O stands for order
D stands for division
M stands for multiplication
A stand for addition
S stands for subtraction.
Consider the given expression,
Using BODMAS rule, solving for brackets first,
Thus, the value of expression is
Answer:
60%
Step-by-step explanation:
It’s simple
He needs to do 60, he has done 36
Percentage = (36/60) * 100
= 60%
Slope-intercept form looks like this: y = mx + b. For your equation, simply add 3x on both sides: y = 3x + 19.
Answer:
2.8 hours
Step-by-step explanation:
Distance = rate * time
If the west-bound train travels at a rate of 80 mph for t hours, then the distance it travels is 80t.
If the east-bound train travels at a rate of 90 mph for t hours, then the distance it travels is 90t.
The distance between the trains after t hours is 476; therefore, the distance of the west-bound train plus the distance of the east-bound train equals the total distance between them, 476:
80t + 90t = 476 and
170t = 476 so
t = 2.8 hours
