In the scale used on a blueprint .1\4 inch represents 2 feet,on the blueprint what is the length of a room with an actual length of 20 feet?
Answer: The length of the room on blueprint = 10 feet.
Step-by-step explanation:
Given: On blueprint,
[tex]\dfrac14[/tex] inch = 2 feet
i.e. 1 actual feet = [tex]2\times\dfrac 14 =\dfrac12\text{ inch}[/tex]
If the actual length of 20 feet, the length of a room on blueprint = [tex]20\times\dfrac12\text{ feet}[/tex]
= 10 feet.
Hence, the length of the room on blueprint = 10 feet.

O
A. 22
B. 44
c. 24
D. 82
E. 28
Answer:
2^4
Step-by-step explanation:
2^2 = 2 * 2 = 4
4^4 = 4*4*4*4 = 256
2^4 = 4*4 = 16
8^2 = 8*8 = 64
2^8 = 2*2*2*2*2*2*2*2 = 256
Hence, 16 can be written as 2^4
Thus, Answer is [C] 2^4

Answer:
I would do C because 2/3 is close to a whole so then you would get -3 and 1/4 is close to 0 so just keep 18 the same which would be -18 so -18 divided by -3 would be correct

The deductions from Jennifer Miller's monthly pay are federal income tax (FIT) of $87, state income tax (SIT) of 2.5% of gross, (CIT) city income tax of 1.2% of gross, social security, and medicare. Her next monthly pay is $3,981.22. Find Jennifer's monthly gross pay.
A) $4,529.05
B) $4,551.23
C) $4,576.58
D) $4,589.08
Answer:
$4,711.31
Step-by-step explanation:
Calculation for Jennifer's monthly gross pay
First step is to calculate The total tax percentage deductions
Using this formula
Total tax percentage deductions =State tax + City tax + Social security + Medicare
Let plug in the formula
Total tax percentage deductions = 3.5% +2.5% +6.2% +1.45%
Total tax percentage deductions = 13.65%
Now let calculate the monthly gross pay
Monthly gross pay= ($3,981.22 +87)/(1-13.65%)
Monthly gross pay= ($3,981.22 +87)/0.8635
Monthly gross pay=$4,068.22/0.8635
Monthly gross pay= $4,711.31

Answer:
0
Step-by-step explanation:
recall that graphically, a solution to two equations when expressed in a graph, is simply the coordinate of the point of intersection.
in our case, it clear that the blue and red lines intersect at (-2,0)
if we compare this to your question, it is clear that [?] = 0
Juanita is riding her bicycle on a trail at the rate of 0.3 kilometers per
minute. Michelle is 11.2 kilometers behind Juanita when she starts traveling
on the same trail at a rate of 0.44 kilometers per minute. Let d represent
the distance in kilometers the bicyclists are from the start of the trail and t
represent the time in minutes. The situation can be represented by the
following system; d=0.3t+11.2 and d=0.44t. How many minutes will it take
Michelle to catch up to Juanita? How far will they be from the start of the
trail? Use the substitution method to determine your answer.
Answer:
It will take Michelle 80 minutes.
They're 35.20 kilometers away from their starting point.
Step-by-step explanation:
We have to find how many minutes it would take Michelle to catch up to Juanita.
We know that Michelle's movement is represented as: d = 0.44t
Juanita's movement is represented as: d = 0.3t + 11.2
To find how many minutes it would take for Michelle to catch up, we will have to solve both equations together and solve for "t", or time.
Solve:
0.44t = 0.3t + 11.2
Subtract 0.3t from both sides.
0.14t = 11.2
Divide both sides by 0.14
t = 11.2/0.14
t = 80
This means that it would take 80 minutes for Michelle to catch up.
To find how far they are, multiply 0.44 by 80.
0.44 · 80 = 35.20
This means that they're 35.20 kilometers away from their starting point.
30% of___ is 15 ?????
Answer:
15 is 30% of 50
Step-by-step explanation:
We have, 30% × x = 15
Multiplying both sides by 100 and dividing both sides by 30,
we have x = 15 × 100/30
x = 50
If you are using a calculator, simply enter 15×100÷30, which will give you the answer.
