the radius of a circle is 9 times of the radius of a smaller circle. the area of the smaller circle is 50 square cenimeters. what is the area of the larger circle​

Answers

Answer 1

Answer:

4050 cm²

Step-by-step explanation:

This is a question of scale factors:

The radius of the larger circle is 9× that of the smaller circle;

This is the linear scale factor of the enlargement of the smaller to larger circle;

The scale factor of the area pertains to 2 dimensions so the scale factor will be the square of the linear scale factor, which is:
9² = 81

The area of the larger circle is found by the area of the smaller circle multiplied by this number:
50 × 81 = 4050

Two angles are supplementary. One angle measures 2x, and the other angle measures 3x - 15. Which equation can you use to find the measure of each angle? 2 x - 3 x - 15 = 180° 2 x 3 x - 15 = 90° 2 x 3 x - 15 = 180° 2 x - 3 x - 15 = 90°.

Answers

Statement:

Two angles are supplementary. One angle measures 2x, and the other angle measures 3x - 15.

To find out:

The equation to find the measure of each angle.

Solution:

Supplementary angles are angles which sum up to 180°.While, complementary angles are angles which sum up to 90°.Here, the sum of the two angles, i.e., 2x and 3x - 15, should be 180°.So, the equation will be: 2x + 3x - 15 = 180°.

Answer:

2x + 3x - 15 = 180°

A motorist travels 160 km at 80 km/h and 160 km at 100 km/h. What is the average speed of the motorist for this trip?.

Analyze problem

since the distance is the same, we will not need to do any solving in that part

so, the average of 80 and 100 is

If a pentagon has a radius of 16 find the perimeter

Answers

Answer:

94.05 units is the perimeter of this pentagon.

Length of each side in pentagon: 2r × Sin(180/n)

                                where r is radius and n is number of sides

Using the formula: 2r × Sin(180/n)

                              : 2*16 * sin(180/5)

                              : 18.8 units

Perimeter = 5(18.8) units........5 as we know pentagon has 5 sides

                = 94.05 units

Alvin's age is three times Elga's age. The sum of their ages is 24. What is Elgna's age

Answers

Answer:

Step-by-step explanation:

Elga's age = x

Alvin's age = 3*x = 3x

Sum of their ages = 24

x + 3x = 24

4x = 24

Divide both sides by 4

x = 24/4

x = 6

3x = 3*6 = 18

Elga's age = 6 years

Alvin's age = 18 years

What is the length of in the figure below?



Select one:


20.8 units


8 units


12 units


14.4 units

Answers

Answer:

Third option

Step-by-step explanation:

Given the following question:

Side c = 24 units

Angle B = 30 degrees
Angle C = 60 degrees
30 + 60 = 90
90 + 90 = 180
(all angles add up to 180 degrees)
Angle A = 90 degrees

Apply the law of sines:

[tex]a=c\times sin(a)[/tex]
[tex]a=24\times sin(60)=20.7846097[/tex]
[tex]20.7846097[/tex]
[tex]8 > 5[/tex]
[tex]20.8[/tex]

Now we have all the angles and two of the sides:

A = 20.8
C = 24

[tex]b=c\times sin(b)[/tex]
[tex]b=24\times sin(30)=12[/tex]
B = 12 units

Angle A - 90 degrees
Angle B - 30 degrees
Angle C - 60 degrees

Side AC - 12 units
Side BC - 24 units
Side BA - 20.8 units

Hope this helps.

Step-by-step explanation:

If this is wrong I am sorry.

Hope this helps

Step-by-step explanation:

This is it. Proportion

if 3 pounds of blue berries cost 10.50

1 pound of blue berries cost 10.50÷3=3.50

Therefore 7 pounds of blue berries cost

3.50 ×7= 24.50

2. Let a be the number of pounds of blue berries you can buy with 35.00

1 = 3.50

a = 35.00

a=35.00÷3.50

a= 10

Therefore, 35.00 is equal to 10 pounds of blue berries.

x = 12

Step-by-step explanation:

The midsegment VY is half the sum of the parallel bases , that is

VY = [tex]\frac{EF+CD}{2}[/tex] , then

3x + 18 = [tex]\frac{1}{2}[/tex] (x + 96) ← multiply both sides by 2 to clear the fraction

6x + 36 = x + 96 ( subtract x from both sides )

5x + 36 = 96 ( subtract 36 from both sides )

5x = 60 ( divide both sides by 5 )

x = 12

Consider two unquie parallel lines what aspects of these two lines are the same ? What aspect of the two lines would have to be different explain your reasoning

Answers

Answer:

The aspect of the lines that are the same is that they have the same slope while the aspect of the lines that are different is that they have different x and y-intercepts

Parallel lines are lines that do not meet in a xy-plane

If the parallel lines are vertical lines, they will both cut the x-axis at different points showing that they will have different x-intercept.

Similarly, if the parallel lines are horizontal lines, they will both cut the y-axis at different points showing that they will have different y-intercept.

Parallel lines are also known to have the same slope. This is the aspect that is common to both lines.
