In the diagram below, RSTU is a rectangle, and the two shaded regions are squares.
If the length of SR is 4 m and the length of ST is 8 m, what is the length of PQ in meters?
Answer:
length PQ = 8.9 m
Step-by-step explanation:
The picture below completes the question you asked. From the picture above RSTU is a rectangle . The two shaded square has a length of sides 8 m and 4 m respectively. The legs of the triangle is the sides of the 2 squares. Therefore, the triangle is a right angle triangle. The adjacent side is 4 m while the opposite side is 8 m.
Using Pythagoras theorem the hypotenuse of the triangle can be calculated below.
Pythagoras theorem
c² = a² + b² Therefore,
c² = 4² + 8²
c² = 16 + 64
c² = 80
square root both sides
c = √80
c = 8.94427191
c ≈ 8.9 m
length PQ = 8.9 m
in triangleABC the side lengths are b=13, ac=21 and bc=x. write a compound inequality the represents the range of possible values for x
Answer:
8 < x < 34
Step-by-step explanation:
ab = 13, ac = 21, bc = x
The longest side of a triangle must be less than the sum of the other two sides.
If 21 is the longest side:
21 < 13 + x
8 < x
If x is the longest side:
x < 13 + 21
x < 34
Therefore, 8 < x < 34.
An estimated 3 out of every 25 men are left-handed.
What percent of men are left-handed?

Mike took clothes to the cleaners three times last month. First, he brought 4 shirts and 1 pair of slacks and paid $15.95. Then he brought 7 shirts, 4 pairs of slacks, and 1 sports coat and paid $49.38. Finally, he brought 3 shirts and 1 sports coat and paid $15.46. How much was he charged for each shirt, each pair of slacks, and each sports coat? Mike was charged $ nothing for each shirt, $ nothing for each pair of slacks, and $ nothing for each sports coat.
Answer:
Each Shirt ≈ $2.49
Each Pair of Slacks ≈ $5.99
Each Sports Coat ≈ $7.99
Step-by-step explanation:
Mike took clothes to the cleaners three times last month.
Let S denotes shirts, P denotes pair of slacks and C denotes sports coat.
First, he brought 4 shirts and 1 pair of slacks and paid $15.95.
Mathematically,
4S + P = 15.95 eq. 1
Then he brought 7 shirts, 4 pairs of slacks, and 1 sports coat and paid $49.38.
Mathematically,
7S + 4P + C = 49.38 eq. 2
Finally, he brought 3 shirts and 1 sports coat and paid $15.46.
Mathematically,
3S + C = 15.46 eq. 3
We are asked to find how much was he was charged for each shirt, each pair of slacks, and each sports coat.
4S + P + 0C = 15.95 eq. 1
7S + 4P + C = 49.38 eq. 2
3S + 0P + C = 15.46 eq. 3
We have 3 equations and 3 unknowns, they can be solved simultaneously using calculator or using online system of equations solver.
Using online system of equations solver yields,
S ≈ $2.49
P ≈ $5.99
C ≈ $7.99
So that means Mike was charge $2.49 for each shirt, $5.99 for each pair of slacks and $7.99 for each sports coat.

William and Stephanie are painting the bedrooms in their house. If he had to paint the bedrooms himself, it would take William four hours to complete the job. If Stephanie alone were to paint the bedrooms, it would take her six hours.
Working together, how long will it take William and Stephanie to paint the bedrooms?
William can do 1/4 of the job every hour by himself.
Stephanie can do 1/6 of the job every hour by herself.
If they don't distract each other while working together, they can do (1/4 + 1/6) of the job every hour.
That's (3/12 + 2/12) = 5/12 job per hour working together.
The complete job will take them (12/5) hour .
That's 2-2/5 hours, or 2 hours 24 minutes.
They both can do the painting in 2hours 24 minutes by solving the fraction.

Ruth has 12 feet of ribbon.
She uses 7 feet of it for a craft project and gives 28 inches of it to her sister.
How many inches of ribbon does she have left?
Enter your answer in the box.
Answer:
See I don't know the answer but I did another one like this if it doesn't help you can report it no problem
Step-by-step explanation:
There are 2 different ways you can solve this problem and you'll get the same answer.
To help you visualize what you have to do, it might be easiest to translate your problem to a unit that easier to use.
Since you only have a ribbon 5 feet long, but you must cut it into 6 pieces, you know it won't even be 1 foot long.
One way to solve the problem would be to translate your 5-foot ribbon into a ribbon divided into inches.
1 foot = 12 inches
To find out how many inches long your ribbon is, you'll need to multiply the number of feet by 12.
Once you know that, then you can more easily divide it by 6. This will tell you how many inches each ribbon is.
Careful! the answer is to be put into feet so once you know how many inches long the ribbon is, you must then divide by 12 to get the correct answer in feet. Don't forget to round to the nearest tenth.
Another way to solve the problem is to simply divide the 5 feet by the number 6 and then round your number to the nearest tenth. It may be harder to visualize the answer this way, but you will get the same answer as if you translated your ribbon into inches and then divided by 12.

two solutions of salt water contain 0.1% and 0.22% salt respectively. A lab technician wants to make 1 liter of solution which contains 0.19% salt. How much of each solution should she use?
Answer:
0.25 L at 0.1% and 0.75 L at 0.22%
Step-by-step explanation:
We have to:
percent quantity
Salt solution # 1 0.1 x L
Salt solution # 2 0.22 (1 - x) L
Mixture 0.19% 1
We are left with the following equation:
0.1 * x + 0.22 * (1-x) = 0.19 * 1
solving:
0.1 * x + 0.22-0.22 * x = 0.19
0.1 * x- 0.22 * x = 0.19 - 0.22
-0.12 * x = -0.03
x = -0.03 / -0.12
x = 0.25
Which means
Salt solution # 1 0.1% 0.25 L should be used and for salt solution # 2 0.22% 0-75 (1 - 0.25) L

You have $4000 to invest. If you'd like to earn exactly $638
in interest each year, how much should you invest in each of
two accounts, one that earns 8% per year and one that
earns 21% per year. (Round your answer to the nearest
dollar)
8%: $
21%: $
Answer:
8%: $1554
21%: $2446
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
[tex]T = E + P[/tex].
In this question:
Two earnings, that i am going to call A(8% per year) and B(21% per year).
Two principals, for A i am going to call P and for B it is the rest, so 4000 - P.
A:
One year, so [tex]t = 1[/tex]
8% interest, so [tex]r = 0.08[/tex]
Earnings A.
[tex]A = P*I*t[/tex]
[tex]A = 0.08P[/tex]
B:
21% interest, so [tex]r = 0.21[/tex]
Principal (4000 - P).
[tex]B = P*I*t[/tex]
[tex]B = 0.21*(4000 - P)[/tex]
You'd like to earn exactly $638 in interest each year.
This means that [tex]A + B = 638[/tex]
Then
[tex]B = 638 - A[/tex]
Now we have to solve the following system:
[tex]A = 0.08P[/tex]
[tex]638 - A = 0.21*(4000 - P)[/tex]
So, on the second equation:
[tex]A = 638 - 0.21*(4000 - P)[/tex]
Replacing on the first:
[tex]A = 0.08P[/tex]
[tex]638 - 0.21*(4000 - P) = 0.08P[/tex]
[tex]638 - 840 + 0.21P = 0.08P[/tex]
[tex]0.21P - 0.08P = 840 - 638[/tex]
[tex]0.13P = 202[/tex]
[tex]P = \frac{202}{0.13}[/tex]
[tex]P = 1553.8[/tex]
Rounding up to the nearest integer
P = 1554.
So on A, the 8% interest, you invest $1554.
On B, the 21% interest, you invest 4000 - 1554 = $2446.

Solve the system of equations using subtraction.
{y=x+4
{y=2x+4
Answer:
x=0, y=4
(0,4)
Step-by-step explanation:
y=x+4
y=2x+4
The directions say substitution not subtraction
Set the two equations equal to each other
x+4 = 2x+4
Subtract x from each side
x+4-x = 2x+4-x
4 = x+4
Subtract 4 from each side
4-4 =x+4-4
0 =x
Now find y
y = x+4
y = 0+4
y = 4
Answer:
(0, 4)
Step-by-step explanation:
Our two equations are:
y = x + 4
y = 2x + 4
We need to use substitution, so let's substitute x + 4 in for y in the second equation:
y = 2x + 4
x + 4 = 2x + 4
x = 0
Plug this value back into one of the equations to solve for y:
y = x + 4
y = 0 + 4 = 4
Thus, the answer is (0, 4).
