-12(5/6a-7/8)+1/14(3 1/2a-1 2/5)

Answers

Answer 1
-12(5/6 a -7/8) + 1/14(3 1/2 a- 1 2/5)

First change mixed fractions to be full fractions

-12(5/6 a -7/8) + 1/14 (7/2 a - 7/5)

Now multiply out

-12(5)/6 a -12(-7)/8) + 7/14(2) a -7/14(5)
-60/6 a + 84/8 + 7/28 a -7/70
-10a + 10.5 + 1/4a - 1/10
-10a + 0.25a +10.5 -0.1
-9.75a + 10.4

*if this =0 and you need to solve for a then
9.75a=10.4
a= 10.4/9.75
a=16/15

Twenty-five volunteers will wear one of 6 blue, 7 green, 8 yellow, and 4 red aprons during an upcoming food drive. If the aprons are assigned randomly, what is the probability that a volunteer is assigned an apron that is NOT green?
A. 6/25
B. 7/25
C. 8/25
D. 18/25

Answers

D. 18/25

To solve this problem, let’s first subtract the ones that ARE wearing green from the total number of volunteers. We’ll subtract 7 from 25 for an answer of 18. Then, we’ll put the 18 over 25 and this will represent how many volunteers are NOT wearing green out of the total number of volunteers. My work is below, please let me know if you have any questions! :)

25 - 7 = 18

18/25 = Probability of volunteers NOT wearing green out of the total number of volunteers

Use similar triangles to solve for the missing lengths below.

If you know how to work this out please help:)

Answers

Answer:

x = 14

y = 18

Step-by-step explanation:

By the property of similar triangles,

If two triangles are similar their corresponding sides will be proportional.

[tex]\frac{AB}{EF}= \frac{AC}{GE}[/tex]

[tex]\frac{5}{10}=\frac{7}{x}[/tex]

x = [tex]\frac{70}{5}[/tex]

x = 14

Similarly, [tex]\frac{AB}{EF}= \frac{CB}{GF}[/tex]

[tex]\frac{5}{10}=\frac{9}{y}[/tex]

y = [tex]\frac{90}{5}[/tex]

y = 18

The automobile insurance
company receives 18 calls in 6
hours. How many calls do they
received in 11 hours?

Answers

Answer:

33

Step-by-step explanation:

An easy way to do this is create a proportion.

[tex]\frac{18}{6} = \frac{x}{11}[/tex]

Keep in mind you could also write this equation as  [tex]\frac{6}{18} = \frac{11}{x}[/tex] as long as you are consistent. The number of calls should be in the same place and the hours should also be in the same place (either the numerator or denominator).

Next, just cross multiply.

6x = (18)(11)

6x = 198

x = 33 calls

Answer:

They would get 33 calls!

You deposit $2700 in an account that pays 3% annual interest compounded weekly. How much money is in the account after 5 years?

Answers

Answer:

A = $3136.86

Step-by-step explanation:

Given the following data;

Principal = $2700

Interest rate = 3% = 3/100 = 0.03

Number of times = 52

Time = 5 years

To find the future value, we would use the compound interest formula;

[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Substituting into the equation, we have;

[tex] A = 2700(1 + \frac{0.03}{52})^{52*5}[/tex]

[tex] A = 2700(1 + 0.0005769)^{260}[/tex]

[tex] A = 2700(1.0005769)^{260}[/tex]

[tex] A = 2700(1.1618)[/tex]

A = $3136.86

Answer:

5500 ml or 5.5 liters

Step-by-step explanation:

First, we should note that there are 1000 milliliters in 1 liter of liquid.

So, in milliliters, Peter filled three containers with 1500 ml, 750ml, and 2250 ml with 1000ml left over.

To find the total amount, we find the sum of all the milliliters:

1500 + 750 + 2250 + 1000 = 5500 ml

Again, we know that there are 1000 milliliters in 1 liter of liquid, so:

[tex]\frac{5500}{1000}[/tex] = 5.5 liters

5500ml I think that is the answer hope this helps
