Racquel works 4 hours a week at the senior center on the weekends.
She gets paid $10.75 an hour. How much money will Raquel have
earned over the course of 3 weeks?
Answer:
$129
Step-by-step explanation:
First, we'll figure out how much Racquel earns per week by multiplying how much she gets per hour by the number of hours she works per week. We can solve 4x10.75 to find out how much money Racquel earns per week. We can solve that to find out that she earns $43 per week. Then, we can multiply that by 3 to find out how much she earns in 3 weeks. Once we solve 43x3 we will end up with an answer of $129 over the course of 3 weeks.

Three sisters are each less than 45 years old. The mode of their ages is 35. The range is 14. What is the mean of their ages? The median?
a.
29.7; 35
c.
35; 30.3
b.
30.3; 28
d.
30.3; 35
Please select the best answer from the choices provided
sorry about the answer choices being mixed up im still in a hurry
Answer:
I'm so sorry I don't know this answer but good luck
Answer: since it doesn't tell you how you get it.
Since the mode of the ages is 35 we know that at least two of the ages are 35. Since the range is 14 we know the third sister is not also age 35. Let x be the age of the third sister. Then we know either 35 - x = 14 or x-35 = 14 (depending if x is younger or older, respectively). Solving both of these gives x = 21 or x = 49. But all the sisters are under the age of 45, so x = 21. Hence, the ages of the sisters are
21, 35, 35.
So, the mean is (35+35+21)/3 = 91/3 =~ 30.3333 ...
The median is 35.

Solve -x > 8 or -x < 4.
{x | -12 < x < -6}
{x | x < -12 or x > -6}
{x | x > -12 or x < -6}
Answer:
-4 < x < -8
Step-by-step explanation:
Given solve -x > 8 or -x < 4.
Solve each inequality first
-x > 8
Divide both sides by -1
-x/-1 > 8/-1
x < -8
Also if -x < 4
Divide both sides by -1
-x/-1 < 4/-1
x > -4
Combine both inequality x < -8 and x > -4
-4 < x < -8
Hence the solution set is -4 < x < -8

The length of a rectangle is 9cm more than four times the width. If the perimeter of the rectangle is 78 cm, what are its dimensions
Answer:
Length is 32. 6 cm and width is 5.9 cm
Step-by-step explanation:
width(w)=w
perimeter(p)=78 cm
length(L) = 4w+9
p=2L+2w
78=2(4w+9)+2w
78=8w + 19 + 2w
10w=59
w=5.9 cm
L=4w+9
L=4(5.9)+9
L=32.6 cm
Therefore length is 32.6 cm and width is 5.9 cm

Answer:
Answer: The correct option is (D) P″(9, -12) and Q″(15, -3).
Step-by-step explanation: Given that triangle PQR is dilated by a scale factor of 1.5 to form triangle P′Q′R′. This triangle is then dilated by a scale factor of 2 to form triangle P″Q″R″.
The co-ordinates of vertices P and Q are (3, -4) and (5, -1) respectively.
We are to find the co-ordinates of the vertices P″ and Q″.
Case I : ΔPQR dilated to ΔP'Q'R'
The co-ordinates of P' and Q' are given by
Case II : ΔP'Q'R' dilated to ΔP''Q''R''
The co-ordinates of P'' and Q'' are given by

Answer:
Answer is 9
Step-by-step explanation:
Remember PEMDAS???
"parenthesis, exponents, multiplication, division, addition, subtraction"
you would first solve the addition inside of the parentheses (1 + 2 = 3), and from there finish the equation as it's written from left to right.
Answer:
9
Step-by-step explanation:
First, we have to solve inside the parentheses because of PEMDAS or GEMDAS, whichever you know. When we add 1+2 we get 3 inside the parentheses and it looks like this: 6/2(3).
Then, we have to divide 6 by 2 before we do anything else. When we divide 6/2, we get 3 and it will look like this: 3(3).
Finally, we have to multiply 3 by 3 because when something is in parentheses, you have to multiply it by the number right before it (next to it). Once we multiply 3*3, we will get our answer of 9.

B. In two or more complete sentences, explain the specific process that you followed in solving for a.
Answer:
a)
[tex]a=23-z[/tex]
b)
First of all, I divided both sides by 2, simplified, and then subtracted z from both sides. Then, I got the final result for 'a'.
Step-by-step explanation:
a) Solving the equation
Given the expression
[tex]2\left(z+a\right)=46[/tex]
Divide both sides by 2
[tex]\frac{2\left(z+a\right)}{2}=\frac{46}{2}[/tex]
simplify
[tex]z+a=23[/tex]
subtract z from both sides
[tex]z+a-z=23-z[/tex]
[tex]a=23-z[/tex]
Thus, the value of a:
[tex]a=23-z[/tex]
b) Work Process
First of all, I divided both sides by 2, simplified, and then subtracted z from both sides. Then, I got the final result for 'a'.

A submarine started at the surface of the water and was moving at -15 meters per minute. The submarine traveled at this rate for 48 minutes before coming to rest on the ocean floor. What is the change in the submarine position?
Given :
A submarine started at the surface of the water and was moving at -15 meters per minute.
The submarine traveled at this rate for 48 minutes before coming to rest on the ocean floor.
To Find :
The change in the submarine position.
Solution :
We need to find the position of submarine position from the surface of water.
Distance travelled = Speed × Time
Distance travelled = -15 m/min × 48 min
Distance travelled = 720 m
Therefore, the position of submarine is 720 m below the surface of ocean.

Determine the percentage change and state whether it's an increase or decrease
Percentage change is calculated as:
[tex]\%Change = \frac{New - Original}{Original} * 100\%[/tex]
[tex]1.\ Original = 5; New = 1.3[/tex]
[tex]\%Change = \frac{1.3 - 5}{1.3} * 100\%[/tex]
[tex]\%Change = \frac{-3.7}5} * 100\%[/tex]
[tex]\%Change = \frac{-3.7 * 100\%}{5}[/tex]
[tex]\%Change = \frac{-370\%}{5}[/tex]
[tex]\%Change = -74\%[/tex]
The percentage change is 74% and it is a percentage decrease
[tex]2.\ Original = 160; New = 136[/tex]
[tex]\%Change = \frac{136 - 160}{160} * 100\%[/tex]
[tex]\%Change = \frac{-24}{160} * 100\%[/tex]
[tex]\%Change = \frac{-24 * 100\%}{160}[/tex]
[tex]\%Change = \frac{-2400\%}{160}[/tex]
[tex]\%Change = -15\%[/tex]
The percentage change is 15% and it is a percentage decrease

[tex]\%Change = \frac{-3}{15} * 100\%[/tex]
[tex]\%Change = \frac{-3* 100\%}{15}[/tex]
[tex]\%Change = \frac{-300\%}{15}[/tex]
[tex]\%Change = -20\%[/tex]
The percentage change is 20% and it is a percentage decrease
[tex]4.\ Original = 7; New = 10[/tex]
[tex]\%Change = \frac{10- 7}{7} * 100\%[/tex]
[tex]\%Change = \frac{3}{7} * 100\%[/tex]
[tex]\%Change = \frac{3* 100\%}{7}[/tex]
[tex]\%Change = \frac{300\%}{7}[/tex]
[tex]\%Change = 43\%[/tex] -- (approximated)
The percentage change is 43% and it is a percentage increase

Step-by-step explanation:
Given that:
Larger square is a dilation of smaller square
Dimension of smaller square (5 - 3) units by (5 - 3) units = 2 by 2
Dimension of larger square (7 - 1) units by (7 - 1) units = 6 by 6
Hence, the scale factor used to create the larger square from the smaller square will be:
Scale factor (x) * side of smaller square = side of larger square
x * 2 = 6
2x = 6
x = 6/2
x = 3
Hence, scale factor used to generate larger square is 3
