THANK YOU SO MUCHHHH!!

A And B Are Complementary. Find The Value Ofb When A Is 72THANK YOU SO MUCHHHH!!

Answers

Answer 1

Step-by-step explanation:

Complementary angles sum to 90°

a + b = 90

72 + b = 90

b = 90 -72

b = 18°

Answer 2
When two angles are complementary, it means that the two angles add up to 90°. Thus when angle a is 72° when angle a and angle b are complementary,

angle a + angle b = 90°
72° + angle b = 90°

*minus 72° on both sides of the eqn*

angle b= 90°-72°
angle b= 18°

How would the length of a circle change if:
a) the radius is increased 2 times
b) the radius is decreased 3 times
c) the diameter is increased 6 times?

Answers

Answer:

a) If the radius of a circle is increased 2 times, the length of the circle (circumference) will increase by a factor of 2π or approximately 6.28 times. This is because the formula for the circumference of a circle is C = 2πr, where r is the radius. If the radius is doubled, then the circumference will also be doubled.

b) If the radius of a circle is decreased 3 times, the length of the circle (circumference) will decrease by a factor of 6π or approximately 18.85 times. This is because the formula for the circumference of a circle is C = 2πr, where r is the radius. If the radius is divided by 3, then the circumference will also be divided by 3 and multiplied by 2π.

c) If the diameter of a circle is increased 6 times, the length of the circle (circumference) will increase by a factor of 6π or approximately 18.85 times. This is because the formula for the circumference of a circle is C = πd, where d is the diameter. If the diameter is multiplied by 6, then the circumference will also be multiplied by 6π

Step-by-step explanation:

pls Mark me As a brainlist

a) length of the circle increased by 2 times.

b) length of the circle decreased by 3 times.

c) length of the circle increased by 6 times.

Length of a circle that is the circumference of the circle is given by the formula = 2πr ( let's say C)

a) Given that the radius of the circle is increased by two times.

R = 2r

Required length of the circle = 2πR = 2π(2r) = 2×2πr = 2C

Hence, the length of the circle will be increased by 2 times.

b) Given that the radius is decreased by 3 times.

R= r/3

Required length of the circle =  2πR = 2π(r/3) = (2πr)/3 = C/3

Hence, the length of circle will be decreased by 3 times.

c) Given that the diameter of the circle is increased by 6 times.

D = 6d = 6×2r = 12r

Required length of the circle = πD= π×12r = 6(2πr) = 6C

Hence, the required length of circle will be increased by 6 times.

Step-by-step explanation:

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Moussa sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.
27 visitors purchased no costume.
112 visitors purchased exactly one costume.
3 visitors purchased more than one costume.

Based on these results, express the probability that the next person will purchase one or more costumes as a percent to the nearest whole number.

There is an equal amount of yellow, blue, green, and red marbles in a bag of 32 marbles. If Ed draws 4 marbles out of the bag with replacement, predict how many of the 4 marbles drawn should be blue.

1
4
8
32

Answers

Answer:

There are 32 marbles in the bag, and 1/4 of them are blue, so there are 32 * 1/4 = 8 blue marbles in the bag.

When Ed draws 4 marbles out of the bag with replacement, the probability of getting a blue marble on any given draw is 1/4.

The number of blue marbles Ed is expected to draw can be found by multiplying the probability of drawing a blue marble on each draw (1/4) by the number of draws (4):

Expected number of blue marbles = (1/4) * 4 = 1

Therefore, Ed is expected to draw 1 blue marble out of the 4 marbles drawn.

1) 1

Reasoning:

There are 4 different colors of marbles and 32 total marbles. 32/4 is 8, so there will be 8 of each at the start.

Because Ed picks 4 marbles, and there are 4 colors, we will divide 4 by 4 (4/4) and get 1.

If a perimetre of a rectangle is 38 cm and length is 12.5 cm What is the Area?

Answers

Answer:

81.25 cm^2

Step-by-step explanation:

perimeter = 2(l + w)

2(12.5 + w) = 38

12.5 + w = 38/2

w = 19 - 12.5

w = 6.5

Area = lw = 12.5 x 6.5 = 81.25

Answer:

81.25 cm²

Step-by-step explanation:

What is the area?

The area is the total space taken up by a flat (2-D) surface or shape. The area is always measured in square units.

To solve for the perimeter of a rectangle, the expression is:

(Let p = perimeter, l = length, w = width)

(l × 2) + (w × 2) = p

To solve for the width of a rectangle when given the perimeter, we can use this expression:

(p - [l × 2]) ÷ 2 = w

Inserting 38 in for 'p' and 12.5 for 'l':

(38 - [12.5 × 2]) ÷ 2 = 6.5

To check our work, we can use the expression to solve for the perimeter:

(6.5 × 2) + (12.5 × 2) = 38

Because the perimeter matches up with 38, we know the width of the rectangle is 6.5cm.

To solve for the area of a rectangle, we use this expression:

(Let a = area)

l × w = a

Inserting 12.5 in for 'l' and 6.5 in for 'w':

12.5 × 6.5 = 81.25

Therefore, the area of the rectangle is 81.25 cm².

Find the value of x

Answers

Answer:

x = 18 !

Step-by-step explanation:

We can see that ∠CHD is equal to ∠GHF as they are vertically opposite angles. We can also see that the angles next to ∠CHD should all add up to 90° as it is a right angle!

This means that we have to add 32 and 32 then minus that from 90...

32 + 32 = 6490 - 64 = 26

As the angle is the same we are now left with...

x + 8 = 26

We just have to solve this by taking away 8 from both sides!

x + 8 - 8 = x26 - 8 = 18x = 18

Hope this helps, have a lovely day! :)

Answer:

The answer is 18°, but please read the explanation so you can solve this problem in the future.

Step-by-step explanation:

To find the angle of x, we have to look at the angles in the first quadrant (in which the lines C and D are) first. To begin, a right angle is 90°. We see that there are two angles of 32° within the right angle (90°). Let's find the sum of 32 and 32.

32 + 32 = 64

Now, we can subtract 64° from 90° to find the angle of CD.

90 - 64 = 26

The angle between C and D is 26°.

If we look below at lines G and F, we can see that they are directly across from lines C and D, so they have the same angles. The arrow pointing to the angle of GF, which we know is 26°, says that x + 8° = 26°. To find x, let's subtract 8 from 26.

26 - 8 = 18

x = 18°
