Answer:
The correct answer would be $136
Step-by-step explanation:
If Karen made $85 in 5 hours and you want to figure out how much she would make in 8 hours, then you would first need to know how much she makes in 1 hour. Do to that, you would divide from 85 by 5, which would then give you 17. So that tells you how much Karen makes in 1 hour, now to find out how much she makes in 8 hours, all you have to do is multiply 17 and 8. Therefore, the answer to your question is Karen would make $136 in 8 hours.

Iliana and Rod were asked to find the difference of (5.1 times 10 Superscript negative 15 Baseline) minus (2.3 times 10 Superscript negative 14 Baseline). As a first step, Iliana rewrote the problem as (0.51 times 10 Superscript negative 14 Baseline) minus (2.3 times 10 Superscript negative 14), and Rod rewrote the problem as (5.1 times 10 Superscript negative 15 Baseline) minus (0.23 times 10 Superscript negative 15 Baseline). Which person wrote a correct possible first step? Why?
Given:
The expression is
[tex](5.1\times 10^{-15})-(2.3\times 10^{-14})[/tex]
First steps of Iliana and Rod are given.
To find:
Which person wrote a correct possible first step.
Solution:
We have,
[tex](5.1\times 10^{-15})-(2.3\times 10^{-14})[/tex]
If we want -15 in the power of 10, then
[tex](5.1\times 10^{-15})-(2.3\times 10^{-14-1+1})[/tex]
[tex](5.1\times 10^{-15})-(2.3\times 10^{-15}\times 10)[/tex]
[tex](5.1\times 10^{-15})-(23\times 10^{-15})[/tex]
Therefore, first step of Rod is incorrect.
If we want -15 in the power of 10, then
[tex](5.1\times 10^{-15+1-1})-(2.3\times 10^{-14})[/tex]
[tex](5.1\times 10^{-14}\times 10^{-1})-(2.3\times 10^{-14})[/tex]
[tex](\dfrac{5.1}{10}\times 10^{-14})-(2.3\times 10^{-14})[/tex]
[tex](0.51\times 10^{-14})-(2.3\times 10^{-14})[/tex]
Therefore, first step of Iliana is correct.
Answer:
B "Only Iliana is correct because Rod incorrectly equated 2.3 times 10 Superscript negative 14 and 0.23 times 10 Superscript negative 15."

Merideth measured 3.25 cups of flour and 1.625 cups of brown sugar into
a bowl. How many cups of ingredients did she have altogether in the
bowl?
Answer:
Step-by-step explanation:
This is just an addition question. If you have a calculator just add the numbers.
3.25 + 1.625 = 4.875 cups in the bowl.
Sometimes you can use another method. Sometimes it is shorter.
3 1/4 + 1 5/8 = 3 2/8 + 1 5/8 = 4 7/8.
7/8 = 0.875

The diagram shows two parallel lines cut by a transversal. One angle measure is shown.
Find the values of A B C D E F and G
Answer:
a= 126
b= 54
c= 126
d= 54
e= 126
f= 54
g= 126
Step-by-step explanation:
To find a you would subtract 54 from 180 which would give you 126
Since a and b are another linear pair they would also add up to 180.
Then you move to c which is a linear pair with 54 so it is 126.
Because a and g are alternate interior angles they are congruent and they you continue with the same process for the first and check by seeing if the angles would be obtuse or acute to see if the angle measures would be correct.
The measure of the angles are a = 54, b = 54, c = 126, d = 54, e = 126, f = 54, and g = 126 degrees.
What are vertically opposite angles?It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.
It is given that:
The diagram shows two parallel lines cut by a transversal.
As we know from the definition of the vertically opposite angles:
b = 54 degrees
a + c = 54 + b (a = c)
2a = 54x2
a = 54 degrees
Since a and g are opposite interior angles, they are congruent, so you proceed with the process as you did for the first and check to see if the angles are acute or obtuse to ensure that the angle measurements are accurate.
Similarly:
b = 54
c = 126
d = 54
e = 126
f = 54
g = 126
Thus, the measure of the angles are a = 54, b = 54, c = 126, d = 54, e = 126, f = 54, and g = 126 degrees.

A math classroom has 30 students. The teacher assigned the students a project and told them they could turn it in on Monday, Tuesday, or Wednesday. 12 of the students turned the project in on Monday. 13 of the students turned the project in on Tuesday. The rest of the students turned the project in on Wednesday. How many students turned their project in on Wednesday?
Answer:
5 students.
30 - 12 - 13 = 5.
Answer:
The answer is 5
Step-by-step explanation:
We need to find out how many students turned in the project on Wednesday. In order to do this, this is what we need to do.
1. First we need to subtract 12 from 30 since 12 is how many students turned in the project on Monday.
2. 30 - 12 = 18
So now we have 18.
3. Next we need to subtract 13 from 18 since we know that 13 is how many students turned in the project on Tuesday.
4. 18 - 13 = 5
At the end we end up with 5.
So 5 students turned in the project on Wednesday.

Find the x and y intercepts of the line
Answer:
x-intercept=1/4 y-intercept= -1/8
Step-by-step explanation:
First, simplify the equation, y= 1/2x-1/8
Then you want to graph the equation with a slope of positive 1/2 starting at -1/8 that'll intercept across the x-axis at 1/4.
To find the y-intercept, you simply have to keep in mind that y=mx+b
b=y-intercept
So our y-intercept is stated in the equation after we simplified it
You plan to take a 7-day trip to California. You estimate that it will cost $275 per day to visit Los Angeles, and $400 per day to visit San Francisco. Your total budget for the 7 days is $2,300. How many days could you spend in each location, so that you spend your entire budget?
Answer:
You can spend 4 days in Los Angeles and 3 days in San Francisco.
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=7 (1)
275x+400y=2,300 (2), where:
x is the number of days to visit Los Angeles
y is the number of days to visit San Francisco
First, you can solve for x in (1):
x=7-y (3)
Now, you can replace (3) in (2):
275(7-y)+400y=2,300
1,925-275y+400y=2,300
125y=2,300-1,925
125y=375
y=375/125
y=3
Finally, you can replace the value of y in (3) to find x:
x=7-3
y=4
According to this, the answer is that you can spend 4 days in Los Angeles and 3 days in San Francisco.

Answer:
An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value. a ≠ b says that a is not equal to b. a < b says that a is less than b. a > b says that a is greater than b. (those two are known as strict inequality)

∠K RQ = 115Step-by-step explanation:
1st step is to get the internal ∠R
R + P + Q = 180R + 50 + 30 = 180R = 180 - 50 - 30R = 100to get the angle ∠K RQ (same as step 1)
K + R + Q = 180K + (100/2) + 15 = 180K = 180 - 50 - 15K = 115therefore, the angle ∠K RQ = 115
Ryan deposits $775 in an account that pays 1.24% simple interest for 4 years.
Brian deposits $775 in an account that pays 1.24% simple interest for 1 year
How much interest did Ryan's account earn the first year?
Answer:
19.22 US$
and
38.44 US$
Step-by-step explanation:
The interest Ryan's account earned for the first year is $9.61.
What is Simple Interest?Simple interest is based on the principal amount of a loan or the first deposit in a savings account.
Mathematically,
SI = PRT/100
here, P is principle amount, R is the rate and T is the time.
Now it is given that,
Principle deposited by Ryan, P = $775
Interest, R = 1.24%
Time, T = 4 years
And for Brian,
Principle, P = $775
Interest, R = 1.24%
Time, T = 1 year
And Simple Interest for Ryan for 1st year,
SI = PRT/100
⇒ SI = (775*1.24*1)/100
⇒ SI = $9.61
Thus, The interest Ryan's account earned for the first year is $9.61.
