Work out the circumference of this circle.
Take a to be 3.142 and write down all the digits given by your calculator,
16.8 cm

Answers

Answer 1

Answer:

50.90 cm

Step-by-step explanation:

The computation of the circumference of this circle is shown below:

As we know that

The circumference of this circle is

= 2πr

where

π is 3.142

r = diameter ÷ 2

= 16.8 ÷ 2

= 8.1 cm

So, the circumference of the circle is

= 2 × 3.142 × 8.1 cm

= 50.90 cm

A trader bought 40 shirts for Birr 220 and sold them at Birr 72 each
Find the profit percentage.

Answers

Given:

Cost price of 40 shirts = Birr 220

Selling price of each shirt = Birr 72

To find:

The profit percentage.

Solution:

We have,

Cost price (CP) of 40 shirts = Birr 220

Selling price (SP) of each shirt = Birr 72

So, the selling price (SP) of 40 shirts is:

[tex]72\times 40=2880[/tex]

We need to find the profit percentage.

[tex]\text{Profit percentage}=\dfrac{SP-CP}{CP}\times 100[/tex]

[tex]\text{Profit percentage}=\dfrac{2880-220}{220}\times 100[/tex]

[tex]\text{Profit percentage}=\dfrac{2660}{220}\times 100[/tex]

[tex]\text{Profit percentage}=1209.09\%[/tex]

Therefore, the profit percentage is 1209.09%.

If the length of the 45° region of this circle is 10 inches, what is the radius of the circle? Use and round to the nearest tenth.

Answers

Answer:

12.71in

step explanation:

The Length of an arc given is expressed as;

A = theta/360 * 2πr

10 = 45/360 * 2 * 3.14r

10 = 1/8 * 6.28r

Cross multiply

10 * 8 = 6.28r

80 = 6.28r

r = 80/6.28

r = 12.74in

Hence the radius is 12.71in

A map uses a scale of 3/4 in = 80 miles. If two buildings are 60 miles apart in real life, how far apart would they be drawn on the map?

Answers

Given:

The scale of a map is [tex]\dfrac{3}{4}\ in=80\ miles[/tex].

The distance between two buildings is 60 miles.

To find:

The distance between the given building on the map.

Solution:

We have,

[tex]\dfrac{3}{4}\ in=80\ miles[/tex]

It means, 80 miles in real life = [tex]\dfrac{3}{4}\ in[/tex] on the map.

1 mile in real life = [tex]\dfrac{3}{4\times 80}\ in[/tex] on the map.

60 mile in real life = [tex]\dfrac{3\times 60}{4\times 80}\ in[/tex] on the map.

                              = [tex]\dfrac{180}{320}\ in[/tex] on the map.

                              = [tex]\dfrac{9}{16}\ in[/tex] on the map.

Therefore, the buildings are [tex]\dfrac{9}{16}\ in[/tex] apart on the map.

Janice bought 3 hamburgers and 4 hotdogs for her cousins and paid $8.50. Brian bought 3 hamburgers and 6 hotdogs for his cousins and paid $10.50. How much did one hamburger cost?
A) 2.00
B) 1.50
C) 1.00
D) 0.75

Answers

Answer:

Cost of each hamburger = $1.50

Step-by-step explanation:

Given:

Cost of 3 hamburger and 4 hotdog = $8.50

Cost of 3 hamburger and 6 hotdog = $10.50

Find:

Cost of each hamburger

Computation:

Cost of each hamburger = h

Cost of each hotdog = d

So,

3h + 4d = 8.50.....EQ1

3h + 6d = 10.50.......EQ2

EQ2 - EQ1

2d = 2

d = 1

3h + 4d = 8.50

3h + 4(1) = 8.50

3h = 4.50

h = 1.50

Cost of each hamburger = $1.50

Graph the following features: Slope = 1/3 Y-intercept = 3

Answers

Answer:

The answer is in the photo.

Step-by-step explanation:

Start by putting a dot on (0,3). Then go up one and to the right three, and that will be your next dot and then just go from there and keep going up one and to the right three. Then to get the other half of your graph you will do the opposite by going down one and to the left three.

The equation of the line that has a slope of (1/3) and the y-intercept of 3 will be 3y = x + 9.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The slope of the line is 1/3 and the y-intercept of the line is 3. Then the equation of the line is given as,

y = (1/3)x + 3

Simplify the equation, then we have

y = (1/3)x + 3

y = (x + 9) / 3

3y = x + 9

The condition of the line that has an incline of (1/3) and the y-block of 3 will be 3y = x + 9. The graph of the line is given below.

Answers

Answer:

Step-by-step explanation:

(133)/7 - 18

133 ÷ 7 = 19

19 - 18 = 1

Answer: y = 1

Step-by-step explanation:

Well if x is 133 then the problem is y = (133/7) -18

and 133/7 is 19

so the problem is y = 19 - 18

and 19 - 18 is 1, so

y = 1

Madeline invests $25,000 in an account that offers a compound interest rate
of 9.5% per year. Which of the following is the correct equation for how much
Madeline will have after 8 years?

Answers

b

25,000 x (0.95)*8 means the interest changes every year and the interest is calculated of the annual rate

The correct equation for how much Madeline will have after [tex]8[/tex] years will be [tex]25000(1+0.095)^8[/tex]  which is in option [tex](b)[/tex].

What is compound interest ?

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest

Amount [tex]=P(1+\frac{R}{100})^t[/tex]

We have,

Principal [tex]=\$25,000[/tex]

Rate[tex]=9.5\%[/tex]

Time [tex]=8[/tex] years

Now,

Using the above mentioned formula,

Amount [tex]=P(1+\frac{R}{100})^t[/tex]

              [tex]=25000(1+\frac{9.5}{100})^8[/tex]

Amount [tex]=25000(1+0.095)^8[/tex]

So, the equation for final amount  is [tex]25000(1+0.095)^8[/tex].

Hence, we can say that the correct equation for how much Madeline will have after [tex]8[/tex] years will be [tex]25000(1+0.095)^8[/tex] which is in option [tex](b)[/tex] .
