Can sombody help me with this ?

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)

The Pie Chart is the best type of chart that could be used to represent the distribution of this data.

A pie chart is a type of circular statistical graph used for the representation of a data set. The graph's segments are proportionate to the percentage of the total in each group.  

However, the proportion of each portion of the pie chart is proportional to the number of the group as a whole.

Therefore, from the given information contains many data sets, each data can be represented in each portion to make a full Pie Chart.

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

125 dollars

Step-by-step explanation:

375÷3

=125

Step-by-step explanation:

Add the ones with like terms.

which means the ones with things in common.

4/5x^2 + 1/4x^2 i'm adding this first because we have x^2 on both sides.

(4/5 + 1/4)x^2

= (5+16/20)x^2

= (21/20)x^2

the next terms are those with x as common.

(1/4 +- 1/5)x...take the sign into consideration while dealing with the terms within the equations.

=(1/4 - 1/5)x

=(5 - 4/ 20)x

= (1/20)x

= (1 × x) / 20

= x/20.

last ones are the constant terms(numbers)

1/6 + 2/3

=12 + 3 / 18

= 15/18...we can simplify this one as well.

= 5 × 3 / 6 × 3

= 5/6.

Now write all the results as a one equation.

descending order starting from the highest degree which is 6/5x^2 --> 1/20x ---> 5/6.

21/20x^2 + x/20+ 5/6.

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

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°

We get fever when our body temperature reaches to 100° C and our normal body temperature is 98°C.

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

Given :-

To Find :-

Solution :-

Here the cost price for Raj is Rs 400 and Selling price is Rs420 .

Here since SP > CP , so there's a profit .

→ Profit = SP - CP

→ Profit = Rs420 - Rs400

→ Profit = Rs 20

Now we can calculate the profit% as ,

→ Profit/CP * 100

→ Rs 20/ Rs 400 * 100 %

→ 20/4%

→ 5%

Hence the profit is 5% .

I hope this helps .

Answer:

Step-by-step explanation:

Cost price of the article = Rs 400

Selling price of the article = Rs 420

As, S.P > C.P

Profit = S.P – C.P

= Rs( 420 – 400)

⠀⠀⠀= Rs 20

So,

Profit percent = (20/400 × 100)%

⠀⠀⠀⠀⠀⠀⠀⠀ = (20/4) %

⠀⠀⠀⠀⠀⠀⠀⠀ = 5 %
