Answer:

r=√(A/π)

r=2.8

Step-by-step explanation:

We want to get (r) alone on one side

A=πr^2

divide each side by π

A/π=r^2

square root each side

√(A/π)=r

r=√(A/π) is the answer to your first question.

now we are given A

r=√((25)/3.14)

put the left side into a calculator

r=2.8216632

round to nearest tenth of a centimeter

r=2.8

Step-by-step explanation:

the 7cm and the 3cm is 21 cm^2                                                                           the 4cm and the 5cm is 20cm^2                                          

the 11cm and the 2cm is 22cm^2                                                                    

basically if your looking for the largest area then the 11cm and the 2 cm is your answer.

82 = x^2 + 1

81 = x^2

x = ±9

y = (3)^2 + 1

y = 10

26 = x^2 + 1

25 = x^2

x = ±5

Answer:

OK I hear you well

Thanks for you

This is equivalent to equivalent to 2 hours, 30 minutes.

======================================================

Work Shown:

1/3 of the house = 50 minutes

3*(1/3 of the house) = 3*(50 minutes)

3/3 of the house = 150 minutes

1 house = 150 minutes

-----------

Sam will need 150 minutes to clean the whole house

Divide this over 60 to convert to hours

150 minutes = (150/60) hours

150 minutes = 2.5 hours which is the final answer

-----------

Or you could say the following

150 minutes = 120 min + 30 min

150 minutes = (120/60) hr + 30 min

150 minutes = 2 hr + 30 min

This shows that 2.5 hours is equivalent to 2 hours, 30 minutes.

Answer:

The given ratio, in simplest form, is 4/7.

Step-by-step explanation:

Rewrite 2/3.5 as 4/7 by multiplying both the 2 and the 3.5 by 2.  This eliminates the decimal fraction.

The given ratio, in simplest form, is 4/7.

The given 2/3.5 in simplest ratio form is 4 : 7.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, A ratio 2/3.5 this can be written as 2 : 3.5 as we know a/b can be written as a : b.

Now, Multiplying 10 to remove the fraction,

2×10 : 3.5×10.

20 : 35.

4 : 7.

Answer:

Step-by-step explanation:

From what I got when I was calculating. I believe they are not equivalent

Answer:

2x+3y=13 ------(1)

4x-y=-2 -----(2)

Multiply (1) by 2,

=> 4x + 6y = 26. ---(3)

Subtract (2) from (3),

4x - 4x + 6y + y= 26 + 2

7y = 28

y = 4

x = (13-3(4))/2

x = 1/2.
