Answer:

5 hours and 30 minutes

Step-by-step explanation:

Convert all fractions to decimals for easier division

9 and 5/8 = 9.625

1 and 3/4 = 1.75

Then divide 9.625 by 1.75 to get the hours amount

9.625 / 1.75 = 5.5

0.5 of an hour is 30 minutes, so the final answer is 5 hours and 30 minutes

Answer:

5.5 hours

Step-by-step explanation:

9.625/1.75=5.5hr

The height of the flagpole to the nearest hundredth is 11.41 m

In order to get the height of the flagpole, we will use the similarity theorem of shapes.

From the given diagram, we will have the expression

1.65/1.15 = x/7.95

Cross multiply

1.15x = 1.65 * 7.95

1.15x = 13.1175

x = 13.1175/1.15

x = 11.406

Hence the height of the flagpole to the nearest hundredth is 11.41 m

Answer:

     x ≈ 67.1

Step-by-step explanation:

The side adjacent to x° is given, along with the hypotenuse. That suggests the relevant trig relation is ...

  Cos = Adjacent/Hypotenuse

  cos(x°) = 28/72 = 7/18

The angle is found from the cosine using the inverse cosine function:

  x° = arccos(7/18)

  x° ≈ 67.1°

Answer:

11.8 m:

Step-by-step explanation:

Volume = pi×r²×h
95 = pi×1.6²×h
h = 95/(pi×1.6²)
h = 11.8122809326
h = 11.8 m (nearest tenth)

Answer:

11.8 m:

Step-by-step explanation:

Volume = pi×r²×h

95 = pi×1.6²×h

h = 95/(pi×1.6²)

h = 11.8122809326

h = 11.8 m (nearest tenth)

Answer:

n/4-9 +3

Step-by-step explanation:

to answer this question we have to analyze the information given.

The quotient of a number means the result of the division of 2 numbers.

In this case the numbers are: a number (n) and 4 . n/4

Nine less than that quotient means we have to subtract 9 to the quotient.

n/4-9

Increase by three: we simply have to add 3

n/4-9 +3

Answer:

d) 35ft

e) 6 seconds

f) 250°

Step-by-step explanation:

If it makes one rotation (360°) in 36 seconds, then it turns 10° every second.

   36 secs = 360°

⇒ 1 sec = 360/36 = 10°

d)  After 9 seconds, it has turned:

9 x 10 = 90°

Therefore, it will be 15 + 20 = 35ft from the wall

e) 60° = 6 seconds

f) 25 seconds = 25 x 10 = 250°

Step-by-step explanation:

percentage is a ratio of a number or fraction to 100

percentage =per(every) + cent (100)

per cent = per 100

percentage calculation formula (%) = (part / whole ) ×100

percentage increase equation = 100 ×( final - initial) /initial

ex1 : 2% is 2 percent = 2/100 =2:100

ex2: 35% = 35/100

48% = 48/100

ex3 : find the following 10% of 25,000

step 1 : convert 10% into fraction = 10/100

step 2 : multiply the fraction with value = 10/100× 25,000

answer = 2,500

ex4 : what is 7% of 68m ?

step 1 : convert 7% into fraction = 7/100

step 2 : multiply the fraction with value = 7/100 × 68

answer = 4.76 m

ex5 : The original price of a shirt was $10. It was decreased to $5 . What is the percent decrease of the price of this shirt?

step 1 : find the amount decreased = $10–$5 =$5

step 2 : write as part / whole = $5 / $10 = $0.5

step 3 : multiply by 100 = 0.5 × 100 = 50%

ex6 : Mary has a monthly salary of $21,000. She spends $350 per month on food. What percent of her monthly salary does she spend on food?

step 1 : write as part /whole and multiply by 100

= ( 350 / 21000 ) ×100 = 1.7 %

ex6 : The price of a pair of shoes was decreased by 21% to $100. What was the original price of the trousers?

step 1 : write % as fraction = 21/100

original price = y

(y × 21/100 ) = amount decreased --------- 1

y - amount decreased = $100 -------------- 2

rearrange equation 2 as;

y - $100 = amount decreased -------------- 3

when you equate both equation 1 and 3 you should get the ans y = $ 126.58

ex6 : The price of an item changed from $120 to $100. Then later the price decreased again from $100 to $80. Which of the two decreases was larger in percentage term?

step 1 : part / whole = (120 - 100) / 120 = 0.17 = 17%

step 2 : part / whole = (100 - 80) / 100 = 0.20 = 20%

The part were the same in both cases but the whole was smaller in the second decrease.

ex7 : A family had dinner in a restaurant and paid $35 for food. They also had to pay 9.5% sale tax and 10% for the tip. How much did they pay for the dinner?

for food = $35

sale tax = 9.5/100 × 35 = $3.33

tip = 10 /100 × 35 = 3.5

total = $45.83

ex8 : Smith invested $5000 for two years. For the first year, the rate of interest was 7% and the second year it was 8.5%. How much interest did he earn at the end of the two year period?

Answer

Interest at the end of the first year

7/100 * 5000 = $350

Interest at the end of the second year

8.5/100 * (5000 + 350) = $454.75

Total interest at the end of the two year period is

$350 + $454.75 = $804.75

Step-by-step explanation:

Answer:

(3, -6)

Step-by-step explanation:

Both equations are equal to y, so you can make them equal to each other:

-2x = 5x-21

Get the same terms on the same side by subtracting 5x from both sides"

-7x = -21

Get x alone by dividing both sides by -7:

x = 3

The simplest way to find y is by filling in 3 for x in the first equation:

y = -2(3)

Multiply:

y = -6

Check your answer by filling in 3 for x in the second equation:

y = 5(3) - 21

Multiply:

y = 15 - 21

Subtract:

y = -6

To check both answers together, fill in 3 for x and -6 for y in both equations (although we already checked both answers above):

-6 = -2(3)

-6 = -6

-6 = 5(3) - 21

-6 = 15 - 21

-6 = -6
