Erin drinks the same amount of milk every day. The equation below represents the proportional relationship between the number of gallons of milk (m) and the numbers of days (d) Erin drinks milk. 16m=2d How long does it take for Erin to drink 1 gallon of milk?
Answers
Answer:
8 days
Step-by-step explanation:
We have that the proportional relationship between the number of gallons of milk (m) and the numbers of days (d) Erin drinks milk is:
[tex] 16m = 2d [/tex]
Hence, the days that would take Erin to drink 1 gallon of milk is:
[tex] d = \frac{16m}{2} = 8m = 8*1 = 8 d [/tex]
Therefore, it would take for Erin 8 days to drink 1 gallon of milk.

angle 1 and angle 2 are supplementary. m angle1 = 3x - 4 and m angle2 = 8x - 14. Find the measure of each angle.
Answers
Answer:
50° and 130°
Step-by-step explanation:
Angle1 and angle2 are supplementary. So, sum of angle1 and angle2 is 180°
3x-4+8x-14=180°
11x-18=180°
11x=198°
x=18°
Angle1 = 3*18 -4 = 50°
Angle2 = 8*18 -14= 130°
4. Write the equation of a line that passes through the point (-8, 2) and is parallel to the
line 3x – 2y = 12.
Answers
Answer:
3x - 2y = - 28
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x - 2y = 12 ( subtract 3x from both sides )
- 2y = - 3x + 12 ( divide all terms by - 2 )
y = [tex]\frac{3}{2}[/tex] x - 6 ← in slope- intercept form
with slope m = [tex]\frac{3}{2}[/tex]
Parallel lines have equal slopes, thus
y = [tex]\frac{3}{2}[/tex] x + c ← is the partial equation
To find c substitute (- 8, 2) into the partial equation
2 = - 12 + c ⇒ c = 2 + 12 = 14
y = [tex]\frac{3}{2}[/tex] x + 14 ← equation in slope- intercept form
Multiply through by 2
2y = 3x + 28 ( subtract 2y from both sides )
0 = 3x - 2y + 28 ( subtract 28 from both sides )
- 28 = 3x - 2y , that is
3x - 2y = - 28 ← equation in standard form

Find the tip amount of a $30 bill with a 20% tip
Answers
Answer:
$6
Step-by-step explanation:
Ok, first thing is first, we need to find what 20% of 30 is. We do that by setting 20% in decimal form and multiplying that by 30.
So first,
0.20 * 30
We cross out the zero in 30 and move the decimal point one spot to the right in 0.20. So now we have:
= 2.0 * 3
Which really is,
= 2 * 3
Which equals,
6
Or,
$6
Yes! We got our answer! Nice work!
(The total bill including the tip would be $36 in case you needed to know)

A poll conducted the day before the student- body presidential election at a midwestern university showed that 53.9 percent favored Mario, the rest favoring Yin Ling. The margin of error was 4.2 percentage points. Should Yin Ling have conceded the election?
Answers
Answer:
No
Step-by-step explanation:
The confidence interval of the percentage of people that favored Mario = number of votes favoring Mario ± Margin of error
The confidence interval = 53.9% ± 4.2% = (49.7%, 58.1%)
This means that between 49.7% to 58.1% of the people would have voted for Mario.
Hence Yin Ling would not have won the election, since there is a probability that 50% would have voted for Mario

Mary Lou has 2 more nickels than pennies, and she has 30 coins all together. Use x for the number of pennies.
a. x + 2 = 30
b. x + (x + 2) = 30
c. 2(x + 2) = 30
d. 2x + 30 = 5
Answers
Answer:
B. x + (x+2) = 30
Step-by-step explanation:
If x equals pennies, then one part of the statement should include an addition of 2, along with the additions of the value of pennies; and it should all equal 30.
Answer:
B. x + (x + 2) = 30
Step-by-step explanation:
x = number of pennies
y = number of nickels
x + y = 30
y = 30 - x
She has two more nickels then pennies, therefore:
y = x + 2
30 - x = x + 2
30 = x + x + 2
x + (x + 2) = 30

Lili has saved $2,500 money from her part time job at a bakery. Since she will not need this money for a few years, she decides to put the money in a 3-year CD (Certificate of Deposit) at a local credit union. The credit union offers Lili 2.75% APR, compounded quarterly. How much will Lili's CD be worth at the end of the 3 years?
Answers
Answer:
Lili's CD be worth at the end of 3 years is $2714.23
Step-by-step explanation:
Lili deposit $2500 at the Annual percent rate 2.75% and for 3 years compounded quarterly.
Let's use formula
A = p[tex](1+\frac{r}{n} )^{n*t}[/tex]
From the given information
p=2500
r =0.0275
t=3
n=4
Plug in these values into the formula
A=2500[tex](1+\frac{0.0275}{4})^{4*3}[/tex]

In the accompanying diagram of parallelogram abode m\angle A=(2x+10) and m/angle=3x. Find the number of degrees in m/angle B (open pictures for diagram)
Answers
Answer:
x = 55
Explanation:
In a parallelogram, the sum of each two consecutive angles is 180°.
In the given parallelogram ABCD, we can note that angles A and B are consecutive angles. This means that their summation is 180°
Therefore:
∠A + ∠B = 180
2x + 15 + x = 180
3x + 15 = 180
3x = 180 - 15
3x = 165
x = 165 / 3
x = 55
Now we can check:
angle A = 2(55) + 15 = 125°
angle B = 55°
angle A + angle B = 125 + 55 = 180°
Hope this helps :)
