A mail carrier delivers 110 letters in 20 minutes. How many letters does he deliver in 40 minutes?

Answer:

[tex] = area \: of \: square - area \: of \: circle \\ = (s \times s) - (\pi {r}^{2} ) \\ = (24 \times 24) - (3.14 \times ( { \frac{24}{2} })^{2}) \\ \\ = 576 - 452.16 \\ = 123.84 \: square \: inches[/tex]

Answer:

3.5325

Step-by-step explanation:

find the area and divide it by 2

1.5*1.5*pi= 1.5*1.5*3.14= 7.065

then divide it by two= 3.5325

When comparing bars side by side, they should have a consistent scale.

Use a side by side bar or a clustered bar graph to enable comparisons of individual values.

Use a stacked bar graph to highlight part to whole relationship.

Use a logarithmic scale if your audience can understand it.

Answer:

2625 cubic meters

Step-by-step explanation:

the volume of a rectangle is V = length x width x height (depth in this case)

so, 50m x 30m x 1.75m = 2625m^3

Answer: irregular

Step-by-step explanation:

it is irregular because its sides are not equal

Answer:

-17

Step-by-step explanation:

1) rewrite: (3 - n) divided by 2 = 10

2) Multiply both sides: (3-n)/ 2 = 10

3) move constant to the right: 3 - n = 20

4) calculate: -n = 20 - 3 then, -n = 17

5) change signs: n = -17

Hope this helped and wasn’t confusing, good luck! :)

Answer:

1. 30 metres

2. 27 squared feet,

3.  25.13 cm

4. 50.27 sqared inches

5. 15.71 metres

6. 380.13 squared metres

7. Area is: 4.52 squared metres Circumference is: 7.54 metres

8. Circumference is: 47.12 feet Area is: 176.71 squared feet

Step-by-step explanation:

1. Since you're rounding pi, your calculation would be:

2 × 3 × 5 = 30

---------------------------------------------------------------------------------------------------------------

2. Since you're rounding pi, it would be:

3 × 3² = 27

---------------------------------------------------------------------------------------------------------------

3. Use the formula for number 5

---------------------------------------------------------------------------------------------------------------

4. Use the formula in number 6

---------------------------------------------------------------------------------------------------------------

5. Formula for the circumference of a circle is:

[tex]C=2\pi r[/tex]

So:

2 × 3.14 × 2.5 = 15.71

---------------------------------------------------------------------------------------------------------------

6.  Formula for the area of a circle is:

[tex]A=\pi r^2[/tex]

So:

3.14 × 121 =  380.13

---------------------------------------------------------------------------------------------------------------

7. Use the formula for numbers 5 and 6 to figure these out

---------------------------------------------------------------------------------------------------------------

8. Use the formula for 5 and 6, except divide the diameter by 2 because the formula only works with the radius
