A map has a scale of 1 centimeter:8 kilometers.
Use the given actual distance to find the distance
on the map: 4 km

Answer:

3.13π

Step-by-step explanation:

One plane is a quarter of a semi-circle, since the semi-circle is split into four equal parts. One quarter of a semicircle is one eighth of a circle, so find the are of a circle with diameter 10ft, and divide by 8:

Diameter is half the radius, so the radius is 5ft.

Area of a circle  = π(radius)²

=5²π

=25π.

We're looking for an eigth of the circles area so: 25π/8 = 3.125π≈3.13π

Answer:

486

Step-by-step explanation:

The solid is a cube. The faces of a cube are 6 congruent squares.

side = 9 ft

surface area = 6 * side²

SA = 6 * (9 ft)²

SA = 486 ft²

Answer:

around 36 is the diameter

Step-by-step explanation:

C=2Pir or pi*d

113.04=pi*d

113.04/pi=d

d≈36

give me brainliest[tex]≈[/tex]

36 units is the diameter of the circle.

The perimeter of a two-dimensional form is the space surrounding it. It represents the total length of the shape's sides. The units used to measure the sides of the form, such as meters, centimeters, inches, or feet, determine the units used to measure the perimeter.

We can use the formula for the circumference of a circle, C = πd,

where C is the circumference and d is the diameter.

Substituting the given value, we have:

113.04 = πd

To solve for d, we can divide both sides by π:

d = 113.04/π

Using a calculator to evaluate this expression, we get:

d ≈ 36

Therefore, the diameter of the circle is approximately 36 units.

Step-by-step explanation:

'h' = hours worked on Monday

'2 + 3h' = hours worked on Wednesday

h + 2 + 3h = 18

4h = 16

h = 4  (Monday)

Answer:

50%

Step-by-step explanation:

Answer: 45

Step-by-step explanation:

Solution for What is 45 percent of 100:

45 percent * 100 =

(45:100)* 100 =

(45* 100):100 =

4500:100 = 45

Now we have: 45 percent of 100 = 45

Question: What is 45 percent of 100?

Percentage solution with steps:

Step 1: Our output value is 100.

Step 2: We represent the unknown value with $x$x​.

Step 3: From step 1 above,$100=100\%$100=100%​.

Step 4: Similarly, $x=45\%$x=45%​.

Step 5: This results in a pair of simple equations:

$100=100\%(1)$100=100%(1)​.

$x=45\%(2)$x=45%(2)​.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{100}{x}=\frac{100\%}{45\%}$

100

x​=

100%

45%​​

Step 7: Again, the reciprocal of both sides gives 45

$\frac{x}{100}=\frac{45}{100}$

x

100​=

45

100​​

$\Rightarrow x=45$⇒x=45​

Therefore, $45\%$45%​ of $100$100​ is $45$

Answer:

40

Step-by-step explanation:

I like to find common factors.

45% and 18 are both divisible by 9.

so

45% ÷ 9 = 5%

18 ÷ 9 = 2

2 is equal to 5%

100% ÷ 5% = 20

so

20 × 2 = 40

100% = 40.

Answer:

i. The ratio of the areas of the two triangles is 5:8.

ii. The area of the larger triangle is 24 in².

Step-by-step explanation:

Let the area of the smaller triangle be represented by [tex]A_{1}[/tex], and that of the larger triangle by [tex]A_{2}[/tex].

Area of a triangle = [tex]\frac{1}{2}[/tex] x b x h

Where; b is its base and h the height.

Thus,

a. The ratio of the area of the two triangles is:

[tex]\frac{area of the smaller triangle}{area of the larger triangle}[/tex]

Area of smaller triangle = [tex]\frac{1}{2}[/tex] x b x h

                                       = [tex]\frac{1}{2}[/tex] x 5 x h

                                       = [tex]\frac{5}{2}[/tex]h

Area of the lager triangle = [tex]\frac{1}{2}[/tex] x b x h

                                           = [tex]\frac{1}{2}[/tex] x 8 x h

                                           = 4h

So that;

Ratio = [tex]\frac{\frac{5}{2}h }{4h}[/tex]

         = [tex]\frac{5}{8}[/tex]

The ratio of the areas of the two triangles is 5:8.

b. If the area of the smaller triangle is 15 in², then the area of the larger triangle can be determined as;

[tex]\frac{area of the smaller triangle}{area of the larger triangle}[/tex] = [tex]\frac{5}{8}[/tex]

[tex]\frac{15}{A_{2} }[/tex] = [tex]\frac{5}{8}[/tex]

5 [tex]A_{2}[/tex] = 15 x 8

       = 120

[tex]A_{2}[/tex] = [tex]\frac{120}{5}[/tex]

    = 24

The area of the larger triangle is 24 in².

Step-by-step explanation:

Interpretation of internet users

Middle East - about 100 million

North America - about 250 million

Europe - about 500 million

Asia - over 1 billion

Now lets look back at the question.

If Africa has 170 million internet users, according to the graphs, which statement is true.

"Africa has fewer users than the middle east"

This is false as Africa has 170 million users whereas The middle east has about 100 million users

170 mil > 100 mil therefore the statement is false

"Africa has more users then Asia"

This is also false as Asia has the most internet users at 1 billion

Africa has no where near as many users at 170 million users therefore the statement is false

"Africa has more users than Europe but fewer than Asia."

We have already identified that Africa has fewer users than Europe so this one could be it if the other part is true.

"Africa has more users than Europe" This is false as Europe has 500 million internet users while Africa only has 170 million users

Therefore this statement is false

"Africa has more users than the Middle East but fewer users than North America."

Africa has more internet users than the Middle East ( 170 mil > 100 mil ) and fewer users than North America ( 250 mil > 170 mil )

therefore this is the correct statement
