Answer:
black: 16/31 blue: 13/31 red 2/31
16 black, 13 blue, 2 red
16+13+2 = 31 total
16/31 is the probability of picking black
13/31 is the probability of picking blue
2/31 is the probability of picking red, so 29/31 is the probability of not picking red (since 31-2 = 29 are not red out of 31 total)

Cynthia besch  wants to buy a rug for a room that is 21 feet wide and 29 feet long. she wants to leave a uniform strip floor around the rug. she can afford to buy 345 square fee of carpeting. what dimensions should the rug have
Step-by-step explanation:
Let x be the width of the uniform strip floor around the rug.
Then the width of the rug is (21 - 2x) and the length of the rug is (29 - 2x).
(21 - 2x)(29 - 2x) = 345
609 - 100x + 4x^2 = 345
4x^2 - 100x + 264 = 0
x^2 - 25x + 66 = 0
(x - 22)(x - 3) = 0
x = 3 or x = 22 (rejected as x must be less that the width of the room)
Hence the width of the rug is 21 - 2(3) = 15 feet and the length of the rug is 29 - 2(3) = 23 feet.

0.7 (3s + 4)-1.1s = 7.9
Answer:
s = 5.1
Step-by-step explanation:
[tex]0.7 (3s + 4)-1.1s = 7.9\\[/tex]
Multiply both sides of the equation by 10
[tex]0.7\left(3s+4\right)\cdot \:10-1.1s\cdot \:10=7.9\cdot \:10\\\\= 7\left(3s+4\right)-11s=79\\[/tex]
Expand
[tex]\mathrm{Expand\:}7\left(3s+4\right)-11s:\\\quad 10s+28[/tex]
Subtract 28 from both sides
[tex]10s+28-28=79-28[/tex]
Simplify
[tex]10s=51[/tex]
Divide both sides of the equation by 10
[tex]\frac{10s}{10}=\frac{51}{10}[/tex]
Simplify
[tex]s=\frac{51}{10}\\\\Decimal = 5.1[/tex]

Find the length of the line segment joining the points J(-4,2) and G(146,52). Round your answer to the nearest tenth if necessary
A.155.0
B.151.9
C.150.5
D.141.4
E.158.1
Answer:
The answer is option E.Step-by-step explanation:
The length of a line segment or the distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
J(-4,2) and G(146,52)
The the length of the line segment joining the points is
[tex] |JG| = \sqrt{ ({ - 4 - 146})^{2} + ({2 - 52})^{2} } \\ = \sqrt{ ({ -150})^{2} + ({ -50})^{2} } \\ = \sqrt{22500 + 2500} \\ = \sqrt{25000} \\ = 50 \sqrt{10} \\ = 158.11388[/tex]
We have the final answer as
158.1 to the nearest tenthHope this helps you

The coordinates of the vertices after a translation 5 units right and 2 units up. C =(1,-8), D =(7,-8), E =(7,0) and F =(1,0)
How to draw a shifted figure if the shifts are provided?Suppose the graph is drawn on the coordinate plane.
Let the shifting be (x,y) → (x+a, y+b)
Then, add 'a' to all x coordinates of the graph's points. Add 'b' to all y coordinates of the graph's points.
The resultant set of new points will be plotted.
Thus it is called origin shift since we think of it as the origin was picked and placed at the point (a,b)(in this case) along with those two axes (x and y axes) and now everything will be measured from this new axes' frame.
Therefore, the coordinates of the vertices after a translation 5 units right and 2 units up.
C =(1,-8)
D =(7,-8)
E =(7,0)
F =(1,0)

A survey showed that 4 out of 5 students own a bicycle. Based on this result, how many of the 800 students in a school own a bicycle? Use any strategy to solve.
Answer:
640 students
Step-by-step explanation:
We are told in the question that 4 out of every 5 students owns a bicycle
This also means , out of every 5 students only 1 does not have bicycle
Then we have a ratio of 4 : 1
This means a fraction of 4/5 students own a bicycle in a school
Based on this result, how many of the 800 students in a school own a bicycle?
This calculated as:
4/5 × 800
= 640 students
Therefore, 640 students out of 800 students own a bicycle

What is the solution to the equation One-third (x minus 2) = one-fifth (x + 4) + 2? x = 12 x = 14 x = 16 x = 26
Answer:
x = 26
Step-by-step explanation:
Given
[tex]\frac{1}{3}[/tex] (x - 2) = [tex]\frac{1}{5}[/tex] (x + 4) + 2
Multiply through by 15 to clear the fractions
5(x - 2) =3(x + 4) + 30 ← distribute and simplify both sides
5x - 10 = 3x + 12 + 30, that is
5x - 10 = 3x + 42 ( subtract 3x from both sides )
2x - 10 = 42 ( add 10 to both sides )
2x = 52 ( divide both sides by 2 )
x = 26
Kaya rented a limousine for prom. The company charges a cleaning fee of $100 and an hourly rate of $45. Her total cost for the night was $437.50. For how many hours did Kaya rent the limousine?
Answer:
Number of hours= 7.5
Step-by-step explanation:
Giving the following information:
The company charges a cleaning fee of $100 and an hourly rate of $45.
Her total cost for the night was $437.50
First, we need to structure the total cost formula:
Total cost= 100 + 45*x
x= number of hours
437.5= 100 + 45x
337.5/45= x
x= 7.5
Number of hours= 7.5
Answer:
Kaya rented the limo for about 7.5 hours
Hope this helps! good luck :)

2.4+10m=6.89 what does m equal
Answer:
m = 0.449
Step-by-step explanation:
Isolate the variable, m. Note the equal sign, what you do to one side, you do to the other. Remember to do the opposite of PEMDAS.
PEMDAS is the order of operation & =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, subtract 2.4 from both sides:
2.4 (-2.4) + 10m = 6.89 (-2.4)
10m = 6.89 - 2.4
10m = 4.49
Divide 10 from both sides:
(10m)/10 = (4.49)/10
m = 4.49/10
m = 0.449
0.449 is your answer for m.
