42 hours Susan worked this week to $378.
Given that, Susan's salary varies directly as the number of hours worked.
We need to find out how many hours did she work this week.
What is the direct variation?Direct variation is a type of proportionality wherein one quantity directly varies with respect to a change in another quantity. This implies that if there is an increase in one quantity then the other quantity will experience a proportionate increase. Similarly, if one quantity decreases then the other quantity also decreases. Direct variation is a linear relationship hence, the graph will be a straight line.
According to the question, last week she earned $144 for working 16 hours. This week she earned $378.
Let the number of hours she works this week be x.
So, the proportion is 144:16::378:x
⇒144×x=16×378
⇒x=42
Hence, 42 hours Susan worked this week to $378.

Write an expression for the
product of 4 and m.
Answer:
4m
Step-by-step explanation:
Expressions do not have equal signs, So for the product of 2 things we just multiply them together.
4m
Answer:
4 × M = P
Explanation:
A product is the result of a multiplication expression, so in this case, We're using variables to represent numbers.
P = Product
We're multiplying 4 and M, so lets rewrite this.
4 × M
This is an incomplete expression, but what will we use for our product We can use a variable. Our variable is P. So lets complete this expression.
4 × m = p.
Or, we can put it in a less complex way.
4m.
This also is a incomplete expression, but it means 4 × m.
1/5 of x is equal to 2.
1/3 ofy is equal to 4. What is x=y?
Answer:
x=10 and y=12
Step-by-step explanation:
if 1/5 of x=2 then 5/5 x (which can be simplified to just x) is 5 times 2, which equals 10. And the same process goes for solving y.

What is the IQR of the following Data Set:
1, 3, 4, 5, 5, 7, 9
Hi there!
We can begin by splitting the data into two equal parts, ignoring the median.
The median is simply the number in the middle of the data, or 5.
Now, we can split the data, taking the three left numbers and the three right numbers.
We have:
Left: 1, 3, 4
Right: 5, 7, 9
Find the medians of these sections. These are the middle numbers again, so:
Left: 3
Right: 7
These are our 1st and 3rd quartiles, respectively. The IQR is the difference between these, so:
7 - 3 = 4 = IQR.

A sphere has a volume of 13.04 cm3.
Calculate the radius of the sphere.
Answer:
[tex]r=1.46 \textsf{ cm (nearest hundredth)}[/tex]
Step-by-step explanation:
Volume of a sphere = [tex]\dfrac43\pi r^3[/tex]
Given volume = 13.04 cm³
[tex]\implies 13.04=\dfrac43\pi r^3[/tex]
Multiply both sides by 3/4:
[tex]\implies 9.78=\pi r^3[/tex]
Divide both sides by [tex]\pi[/tex]:
[tex]\implies \dfrac{9.78}{\pi}=r^3[/tex]
Cube root both sides:
[tex]\implies r=\sqrt[3]{\dfrac{9.78}{\pi}}[/tex]
[tex]\implies r=1.460146149...[/tex]
[tex]\implies r=1.46 \textsf{ cm (nearest hundredth)}[/tex]

Answer:
25-5(29)=-120
Step-by-step explanation:
Answer:6
Step-by-step explanation:
We are dealing with 3,000 ice creams in supply, and so we have q=3. Hence S(q), the price of each item when q are in supply is given by

What value of k makes the equation true?
k – 3(k + 5) – 0.5 = 3(0.25k + 4)
Answer:
k = - 10
Step-by-step explanation:
k - 3(k + 5) - 0.5 = 3(0.25k + 4) ← distribute parenthesis on both sides
k - 3k - 15 - 0.5 = 0.75k + 12
- 2k - 15.5 = 0.75k + 12 ( subtract 0.75k from both sides )
- 2.75k - 15.5 = 12 ( add 15.5 to both sides )
- 2.75k = 27.5 ( divide both sides by - 2.75 )
k = - 10

About 8% of the population of a large country is math phobic. If two people are randomly selected, what is the probability both are math phobic? What is the probability at least one is math phobic?
Answer:
the chances both are is=.64%
the chances of only one is=15.36%
Step-by-step explanation:
8%=.08
.08x.08= .0064=.64%
1-(1-0.08)×(1-0.08)
1-.92x.92
0.1536=
15.36%
a) The probability both are math-phobic: 0.0064 or 0.64%.
b) The probability that at least one is math-phobic is 0.1536 or 15.36%.
To determine the probability that both selected people are math-phobic, we can use the multiplication rule of probability.
Since the selection is random, the probability that the second person is math-phobic is also 0.08.
To find the probability that both events occur, we multiply the individual probabilities:
Probability of both being math-phobic = 0.08 x 0.08 = 0.0064
Therefore, the probability that both selected people are math-phobic will be 0.0064 or 0.64%.
To find the probability that at least one person is math-phobic, we can use the complement rule of probability.
The probability that the first person is not math-phobic ;
1 - 0.08 = 0.92.
Similarly, the probability that the second person is not math-phobic is also 0.92.
Probability of none being math-phobic = 0.92 x 0.92 = 0.8464
Probability of at least one being math-phobic = 1 - 0.8464 = 0.1536
Therefore, the probability that at least one person is math-phobic is 0.1536 or 15.36%.

a -4 times 10^-10 meters
b- 4 times -2 meters
c- 4 times 10^2 meters
d- 4 times 10^8 meters
Answer: D!!!!!!!!!!!!!
The required reasonable measure for the earth-moon distance is 4 times 10^8 meters. Option D is correct.
Given that,
The distance from the Earth to the Moon is about a hundred times the distance from California to New York. What is a reasonable measure for the Earth-Moon distance is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Options A, B, and C is reasonable false because all are impossible terms for the distance, earth to the moon.
Option D is reasonably correct because 4 * 10^8 seems larger as the distance from the earth to the moon is also larger.
Thus, the required reasonable measure for the earth-moon distance is 4 times 10^8 meters. Option D is correct.
