Can someone please help me!!

Mathematics
1 answer:
GrogVix [38]3 years ago
5 0

Answer:

8. $21 is your constant number, so nothing changes. $5.50 is a number that changes based on how many months have passed. So your equation should be: 21 + 5.50x

9. Since the number 7 is a percentage in this problem, it should be written as .07. Since the total price is unknown, it should be written as x. By using the equation <em>x</em><em> </em><em>*</em><em> </em><em>.</em><em>0</em><em>7</em><em>,</em><em> </em>you have the <u>a</u><u>m</u><u>o</u><u>u</u><u>n</u><u>t</u><u> </u>that should be added to the total price. The final equation should be x * .07 since you have an unknown total price.

10. f(x)= means the same thing as y=, so they should be treated the same. Since f(x)=14, you should plug it into the equation (by putting 14 into any place that you see an x) , giving you f(14)=1/4(14)+10. The final answer should be f(14)=13.5 or f(x)=13.5

11. The dependent variable should be the three facts since they're dependent on the people listed. If they wasn't any people listed, there wouldn't be three facts, therefore making the people listed the independent variable.

Hope this helped!

elena55 [62]

Answer:

Always

Step-by-step explanation:

The rules for positive numbers is that addition and multiplication makes numbers larger. Subtraction and division makes numbers smaller.

Since 12 is a positive number, the result of dividing a positive number by 12 will make it smaller.

Rename 4/7 as a percent. Round to the nearest tenth of a percent if necessary.
enyata [817]

Answer:

Part 1) Option C. 57.1%

Part 2) Option B. 70.9%

Part 3) Option C. 66 2/3 %

Part 4) Option A. About 16

Part 5) Option A. About $12

Part 6) Option B. About $9

Part 7) Option B. x/50=70/100

Part 8) Option B. 25%

Part 9) Option D. 800

Part 10) $1,770

Step-by-step explanation:

Part 1) Rename 4/7 as a percent

we know that

To rename a number as a percent, multiply the number by 100

so

(4/7)*100=400/7=57.1%

Part 2) Rename .709 as a percent

we know that

To rename a number as a percent, multiply the number by 100

so

0.709*100=70.9%

Part 3) If 1/3 is equivalent to 33 1/3% what percent is equivalent to 2/3?

we know that

33 1/3%=(33*3+1)/3 %=100/3 %

By proportion

(100/3 %)/(1/3)=x/(2/3)

x=200/3 %=66 2/3 %

Part 4) Alice plays basketball. In one game she shoots 21 free throws and makes 81.25% of them. Estimate how many she makes

To find the exact value multiply the total shoots by the percentage

21*(81.25/100)=17.06

so

<em>To find the estimate value</em>

21 shoots is about 20

81.25% is about 80%

so

20*(80/100)=16

the answer is about 16

Part 5) Estimate 48% of 23.95

To find the exact value multiply the number by the percentage

23.95*(48/100)=11.50

<em>To find the estimate value</em>

23.95 is about 24

48% is about 50%

so

24*(50/100)=12

Part 6) The bill at a restraint is $58.50 and Mrs. Johnson wants to leave a 15% tip. Approximately how much money

To find the exact value multiply the bill by the percentage

so

$58.50*(15/100)=$8.78

<em>To find the approximate value</em>

$58.50 is about $60

$60*(15/100)=$9

Part 7) Which proportion can be used to solve the following percent problem? What is 50% if 100% is 70?

using proportion

x/50=70/100

x=70*50/100

x=35

Part 8) What percent of 50 is 12.5?

using proportion

50/100%=12.5/x%

x=100*12.5/50

x=25%

Part 9) 50 Is 6.25% of what number?

using proportion

50/6.25%=x/100%

x=100*50/6.25

x=800

Part 10) Chris works at Higgins’ Automart and is selling a new Shelby Mustang for $59,000. If he earns a commission of 3%, how much money does he earn?

we know that

$59,000 ------> represent the 100%

using proportion

Find how much money represent 3% of the commission

59,000/100%=x/3%

so

X=$59,000*(3/100)=$1,770

Can someone plzz help me wit #2 plzz
evablogger [386]

F = \frac{s+24}{3}

express the equation with F on the left side

3F - 24 = s ( add 24 to both sides )

3F = s + 24 ( divide both sides by 3 )

F = \frac{s+24}{3}
