Answer:
c. 6/15 = 10/25
Step-by-step explanation:
Using the hint, we can form the cross products of the offered choices:
a. 6(12) vs 9(9) ⇒ 72 vs 81 . . . not a proportion
b. 8(21) vs 16(10) ⇒ 168 vs 160 . . . not a proportion
c. 6(25) vs 15(10) ⇒ 150 vs 150 . . . IS A PROPORTION
d. 4(27) vs 14(6) ⇒ 108 vs 84 . . . not a proportion
__
The cross products are the same for choice C, so that is a pair of ratios that form a proportion:
6/15 = 10/25
Chanelle selects a marble from a container and then returns it to the container. When she does this 3 times, the probability of choosing a red marble all 3 times is 1/216. Based on this information, what is the probability of Chanelle choosing a red marble the first time she selects a marble?
Answer:
1 ÷ 6
Step-by-step explanation:
Let us assume the probability of the red marble for selecting it first time be x
And, it is to be done 3 times
that means
= 1 ÷ x × 1 ÷ x × 1 ÷ x
This equivalent to = 1 ÷ 216
And the 216 could be calculated by multiplied 6 3 times i.e.
= 6 × 6 × 6
= 216
So, the probability for selecting it for a first time is
= 1 ÷ 6
Tyrone's hourly wage is $18 and his net pay is 72% of his earnings Tyrone spends about $1800 on his monthly expenses if Tyrone works 40 hours per week and has no other sources of income what is his total monthly cash inflow it as soon as there are four pay periods per month
Answer:
The monthly cash inflow is $273.6
Step-by-step explanation:
It is given that hourly wage is $18 and his net pay is 72% of his earnings.
First, calculate the 72% of $18.
72% of his earnings is [tex]\$18\times \frac{ 72}{100}= \$12.96[/tex].
Tyrone works 40 hours per week .
The number of working hours in a month is: [tex]40\times4=160 \text{ hours}[/tex]
For 1 hour is he was getting $12.96.
For 160 hours he will get: [tex]160\times 12.96=\$2073.6[/tex]
His total monthly cash inflow is $2073.6 - $1,800=$273.6
Hence, the monthly cash inflow is $273.6

Answer:
Step-by-step explanation:
a———-b———c^39. ^?bc=39 segment addition postulateAnswer:
The answer is BC = 39.

Venus Waldo reviewed her account statement and wanted to verify that the interest amount was correct. Her new balance was $12,098.12 and her previous balance was $9,043.20. She had deposited $3,298.45 and withdrawn $300.00. Find the interest earned on Venus' savings account.
Answer:
The interest on the savings account is $46.47
Step-by-step explanation:
Here, we want to know the interest earned on the savings account.
The difference between the new and previous balance will be; 12,098.12 - 9,053.20 = $3,044.92
The difference between amount deposited and amount withdrawn is 3,298.45 - 300 = 2,998.45
This is the amount that is supposed to be on the account without interest
So the interest earned would be; 3044.92 - 2,998.45 = $46.47

Questions 7 and 8 multiple choice
Problem 7
Answer: Choice A) 7--------------------------------------
Work Shown:
p(x) = x^4+x^3-kx-x+6
If (x-2) is a factor of p(x), then x = 2 is a root of p(x). This is a special case of the remainder theorem.
This means p(2) = 0
Replace every x with 2 and solve for k
p(x) = x^4+x^3-kx^2-x+6
p(2) = 2^4+2^3-k(2)^2-2+6
p(2) = 16+8-4k-2+6
p(2) = 28-4k
0 = 28-4k .... replace p(2) with 0
4k = 28
k = 28/4
k = 7
The polynomial
p(x) = x^4+x^3-7x^2-x+6
has the factor (x-2)
============================================
Problem 8
Answer: D) 40--------------------------------------
Work Shown:
Check out the diagram below to see the synthetic division table. We're after the remainder which is highlighted in yellow.
An alternative is to use direct substitution
p(x) = 2x^4+4x^3-x^2-5
p(-3) = 2(-3)^4+4(-3)^3-(-3)^2-5 ... replace every x with -3
p(-3) = 2(81)+4(-27)-9-5
p(-3) = 162-108-9-5
p(-3) = 40
This helps confirm we got the right remainder and the right answer.

Nisha is looking out the window of her apartment building at a sculpture in a park across the street. The top of Nisha's window is 60 feet from the ground. The angle of depression from the top of Nisha's window to the bottom of the sculpture is 25°. How far away from the building is the sculpture? Round your answer to the nearest hundredth.
A) 25.36 feet
B) 27.98 feet (NOT correct)
C) 100.22 feet
D) 128.67 feet (NOT correct)
Answer:
It is D 128.67
Solution:
Opposite=60
Angle=25degrees
Adjacent=?
Hypotenuse=?
We need to solve for the adjacent so don't worry about hypotenuse value.
Equation to solve for Adj.
tan(x)=Op./Hyp.
tan(25)=60/adj.
You then flip it
Adj.=60/tan(25)
Adj.=60/0.46630765815
Adj.=128.67 feet

(a) A square has a perimeter or 32 cm. What is the length of each side?
cm
(D) A square has an area of 144 m². What is the length of each side?
Answer:
A) 8cm
B) 12cm
Step-by-step explanation:
A) Perimeter = 4 × L
where L is the length of the sides
32 = 4 × L
32/4 = L
L = 8cm
B) Area = L^2
144 = L^2
L = square root of 144
L = 12cm
a)
The length of each side is 8 cm.
d)
The length of each side is 12 m.
What is a square?A square is a two-dimensional figure that has four sides and all four sides are equal.
The area of a square is given as side².
We have,
The perimeter of the square = 32 cm
Area of the square = 144 m²
Now,
Perimeter = 32 cm
4 Side = 32 cm
Side = 32 /4
Side = 8 cm
Area = 144 m²
Side² = 144
Side = 12 m
Thus,
The length of the side is 8 cm.
The length of the side is 12 m.

The head track coach for PCTVS has a big track meet coming up. He knows that his biggest rival is Clifton and the entire track meet will come down to one event, the 100 meter relay race. The relay race is comprised of 4 runners from each team who run 100 meters each. The track coach has been working on his projections for the race and knows it will come down to the last leg of the race. He is having difficulty with his algebra skills, so he has asked the Honors classes at PCTI to help him make a projection for the race. He knows that on the last leg of the race, his runner will be leading the race. PCTVS's runner runs at a speed of 10.1 meters per second. Clifton's runner runs at a rate of 10.9 meters per second and will start the last leg of the race 0.8 seconds behind the runner from PCTVS. Will PCTVS win the relay race?

To make purple paint you
must mix 2 parts blue with 5
parts red. If I use 13 cups of
blue, how much red would I
need for the same shade of
purple?
Answer:
you need 32.5 cups of red for the same shade of purple
Step-by-step explanation:
2:5
13:32.5
Answer:
32.5 cups of red
Step-by-step explanation:
Lets take it step-by-step.
So to make purple paint you mix 2 parts of blue and 5 parts of red. So if you use 13 cups of blue you need to use 32.5 cups of red because...
13 divided by 2 = 6 1/2, so you would have to multiply 5 x 6 1/2 which is 32.5
Next time you come across a problem like this take the large number you have Ex. 13, and divide it by the smaller number you know Ex. 2, and then multiply the number that you've gotten by dividing Ex. 6 1/2, with the other small number Ex. 5, and then you have your answer.

3(5 - x) = 7x - 2
Answer:
[tex]\boxed {x = \frac{17}{10}}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]3(5 - x) = 7x - 2[/tex]
-Use Distributive Property:
[tex]3(5 - x) = 7x - 2[/tex]
[tex]15 - 3x = 7x - 2[/tex]
-Take [tex]7x[/tex] and subtract it from [tex]-3x[/tex]:
[tex]15 - 3x - 7x = 7x - 7x - 2[/tex]
[tex]15 - 10x = -2[/tex]
-Subtract [tex]15[/tex] to both sides:
[tex]15 - 15 - 10x = -2 - 15[/tex]
[tex]-10x = -17[/tex]
-Divide bot sides by [tex]-10[/tex]:
[tex]\frac{-10x}{-10} = \frac{-17}{-10}[/tex]
[tex]\boxed {x = \frac{17}{10}}[/tex]
So, the value of [tex]x[/tex] is [tex]\frac{17}{10}[/tex].

A particle travels in a circle around a fixed point at 16 revolutions per minute. The linear velocity of the particle is 240
inches per minute.
What is the distance, in inches, between the particle and the fixed point?
Answer:
15 inches
Step-by-step explanation:
We are given;
Linear velocity; V = 240 in/min
ω = 16 rev/min
Now, in circular motion, formula for linear velocity is;
V = ωr
Where ω is angular velocity and r is radius which is the distance between the object and the fixed point.
Thus;
240 = 16r
r = 240/16
r = 15 inches
