The measure of ⏜ is 161°, and the measure of ⏜ is 107°.

What is the measure of ∠ ?

Answers

Answer:

m<AEB = 46°

Step-by-step explanation:

Given:

Arc AD = 161°

Arc BC = 107°

Required:

m<AEB

Solution:

Vertex angle = ½(sum of intercepted arcs) => Theorem for angle inside a circle and its intercepted arcs)

This:

m<AED = ½(AD + BC)

m<AED = ½(161 + 107) => Substitution

m<AED = ½(268) = 134°

✔️m<AEB = 180° - m<AED => Linear pair theorem

m<AEB = 180° - 134° => substitution

m<AEB = 46°

Answers

Answer:

x = 31 and y= 11

Step-by-step explanation:

Since sum f angles on a straight line is 180°, hence;

2x+8+3x+17 = 180

Collect like terms

5x+25 = 180

5x = 180-25

5x = 155

x = 155/5

x = 31°

Similarly;

3x+17+5y+15 = 180

Substitute x = 31 into the equation

3(31)+17+15+5y = 180

93+32+5y = 180

125+5y =180

5y = 180-125

5y = 55

y = 55/5

y = 11°

Hence x = 31 and y= 11

The radius of the other similar circle is, 6 inches

What is a circle?

In mathematics, the circle is a two dimensional rounded figure which has no corner edges.

Standard form = (x - a)² + (y - b)² = r²

Angle = Arc / Radius

Given that,

The two arc lengths for the circles are equal

One circle has a radius of 8 inches and a shaded sector with an angle measure of 90 degrees

The second circle has a shaded sector with an angle measure of 120 degrees

The radius of second circle = ?

α = 90°

It is known that,

π radian = 180°

1°  = π/180 radian

Now,

α = 90 × π/180

   =  π/2

β  = 120°

   =  120 × π/180

   =   2π/3

In Circle 1,

Angle = Arc / Radius

π/2 = Arc/8

Arc = 4π

In both the circles, length of arc is same,

In Circle 2,

Angle = Arc / Radius

2π/3  = 4π/Radius

Radius = 6

Thus, the radius of second circle is 6 inches

A balloon lifts off the ground and reaches a height of 200m. The total mass of the balloon is 1000 kg. What is the GPE of the balloon?

Answers

Answer:

1,960,000Joules

Step-by-step explanation:

Gravitational Potential Energy is expressed as;

GPE = mgh

m is the mass

g is the acceleration due to gravity

h is the height

Given

m = 1000kg

h = 200m

g = 9.8m/s

Substitute;

GPE  = 1000 * 9.8 * 200

GPE = 9800 * 200

GPE = 1,960,000Joules

Hence the GPE of the balloon is 1,960,000Joules

help me pretty please <3 (brainliest)

Answers

Answer:

The value is 0.025

Step-by-step explanation:

We get the z-score that is equal to the given value

Mathematically we have this as:

z-score = (x-mean)/SD

x = 93

mean =79

SD = 7

So we have the z-score as;

z-score = (93-79)/7 = 14/7 = 2

So we want to calculate the probability equal to the calculated z-score value of 2

Using the standard normal distribution table, we have this value as;

1 - 0.975= 0.025

Problem 1:

The height of water in a bathtub, w, is a function of time, t. Let P represent this function. Height

is measured in inches and time in minutes.

Match each statement in function notation with a description.

A: P (0)=0

1: After 20 minutes, the bathtub is empty.

B:P (4)= 10

2: The bathtub starts out with no water.

C:P (10) = 4

3: After 10 minutes, the height of the water is 4 inches.

D: P (20) = 0

4: The height of the water is 10 inches after 4 minutes.

Answers

Answer:

A = 2

D = 1

B = 4

C = 3

Step-by-step explanation:

Height of water in bathtub is a function of water in bathtub.

P(t) = w ; t = time ; w = height of water.

A: P (0)=0 ; At time, t = 0 ; height of water = 0, there is no water on bathtub

2: The bathtub starts out with no water.

D: P (20) = 0 ; At time, t = 20 ; w = 0 ;the tub is empty.

1: After 20 minutes, the bathtub is empty.

B:P (4)= 10 `; At t = 4, w = 10 ; height of water in bath tub is 10

4: The height of the water is 10 inches after 4 minutes

C:P (10) = 4 ; At t = 10, w =4, height of water in bathtub = 4 inches

3: After 10 minutes, the height of the water is 4 inches.
