Answer:
1.A. 88.89
2.B.6.3%
3.C.64.92%
Step-by-step explanation:
1.
to covert it into percentage multiply it with 100
then it becomes 88.888
rounding off to the nearest hundred it becomes 88.89
2. to convert into percentage multiply it with 100
therefore 0.063×100=6.3%
3. to find percentage
%= (no of students using mobile / total no of students )× 100
=
×100
=64.918
Rounding off to nearest hundred it becomes 64.92%
Answer:
See explanation
Step-by-step explanation:
From the graph,
- After 1 hour passed, 2 inches of show fell
- After 5 hours passed, 10 inches of snow fell
- And so on
This means, that points (1,2), (5,10) lie on the graph. This graph passes through the origin, so its equation is

where k is the slope
Find k:

so the equation is
and the slope is k = 2.
The slope means how many inches of snow fell in 1 hour.
In 1 hour, 2 inches of snow fell.
Answer:
Step-by-step explanation:
First find the population density of AZ and then compare it to the US average of 87.4 people per square mile:
6,482,505
---------------- = 56.9 people per square mile
113,998
The ratio of AZ's population density to the national average is:
56.9
--------- or 569/874
87.4

#1 x-8a/6=3a-2x
Multiply each term by 6 to remove fraction .
6(x-8a/6)= 3a(6)-2x(6)
X-8a=18a-12x
Add 12x both sides
X+12x-8a=18a-12x+12x
13x-8a= 18a
Add8a both sides
13x-8a+8a=18a+8a
13x=26a
Divide each side by 13
13x/13=26a/13
X= 26a/13
Reduce and cancel common factor .
X= 13(2a)/13(1)
X=2a/1
X=2a
Problem #2
3x-2a=7a find a
Subtract 3x both sides
3x-3x-2a=7a-3x
-2a=7a-3x
Subtract 7a both sides
-2a-7a=7a-7a-3x
5a=-3x
Divide both sides by 5
5a/5=-3x/5
A= -0.6 or -3/5
Problem#3
3(bx-2ab)=b(x-7a)+3ab
Distributed property
3(bx)+3(-2ab)=b(x)+b(-7a)+3ab
Simplify
3bx-6ab=bx-7ab+3ab
Add -7a plus 3ab on right side
3bx-6ab= bx-4ab
Subtract bx both sides
3bx-bx-6ab= bx -bx -4ab
Simplify
2bx-6ab= -4ab
Add 6ab both sides
2bx-6ab+6ab=6ab-4ab
2bx=2ab
Divide 2b both sides
X= 2ab/2b
Cancel 2 common
X= ab/b
X=a
