In circle D, angle ADC measures (7x + 2)°. Arc AC

measures (8x - 8)º.

What is the measure of angel ABC

Answers

Answer:

The measure of angle ABC is 36° ⇒ 1st answer

Step-by-step explanation:

Let us revise some important facts in the circle

The measure of the center angle is equal to the measure of its subtended arc

The measure of the inscribed angle is equal to half the measure of the central angle subtended by the same arc

The vertex of a central angle is the center of the circle and its sides are radii in the circle

The vertex of an inscribed angle is a point on the circle, and its sides are chords in the circle

In circle D

∵ D is the center of the circle

∵ A and C lie on the circle

- DA and DC are radii

∴ ∠ADC is a central angle subtended by arc AC

∴ m∠ADC = m of arc AC

∵ m∠ADC = (7x + 2)°

∵ m of arc AC = (8x - 8)°

- Equate them to find x

∴ 8x - 8 = 7x + 2

- subtract 7x from both sides

∴ x - 8 = 2

- Add 8 to both sides

∴ x = 10

Substitute the value of x in the measure of ∠ADC

∵ m∠ADC = 7(10) + 2 = 70 + 2

∴ m∠ADC = 72°

∵ AB and BC are two chords in circle D

∴ ∠ABC is an inscribed angle subtended by arc AC

∵ ∠ADC is a central angle subtended by arc AC

- By using the 2nd fact above

∴ m∠ABC =  m∠ADC

∴ m∠ABC =  × 72

∴ m∠ABC = 36°

The measure of angle ABC is 36 degrees

Circle geometry

To get the required measure of m<ABC, we will use the theorem that states that the measure of the central angle is equal to the measure of its subtended arc and;

The vertex of a central angle is the center of the circle and its sides are radii in the circle

According to the given circle D

∠ADC is a central angle subtended by arc AC

m∠ADC = m of arc AC

m∠ADC = (7x + 2)°

m of arc AC = (8x - 8)°

Equate to find the value of x

8x - 8 = 7x + 2

x - 8 = 2

x = 10

Substitute the value of x in the measure of ∠ADC

m∠ADC = 7(10) + 2 = 70 + 2

m∠ADC = 72°

∠ADC is a central angle subtended by arc AC

m∠ABC =  0.5 × 72

m∠ABC = 36°

Hence the measure of angle ABC is 36 degrees

The manager of the shelter wants the kittens distributed equally among the crates. How might that be done? How many kittens will end up in each crate? Need help fast!!!

Answers

Answer:

2 kittens per crate

Step-by-step explanation:

The kittens in a room at an animal shelter are arranged in five crates, as shown.

The manager of the shelter wants the kittens distributed equally among the crates. How might that be done? How many kittens will end up in each crate?

Crate 1 = 2 kittens

Crate 2 = 1 kitten

Crate 3 = 4 kittens

Crate 4 = 3 kittens

Crate 5 = 0 kitten

Total kittens = 2 + 1 + 4 + 3 + 0

= 10 kittens

To distribute them equally among the crates, divide the number of kittens by the number of crates

Kitten per crate = number of kittens / number of crates

= 10 kittens / 5 crates

= 2 kittens per crate

Kitten per crate = 2 kittens per crate

Answers

Answer:

r = 5

Step-by-step explanation:

(r + 8)^2 = r^2 + 12^2

r^2 + 16r + 64 = r^2 + 144

16r = 80

r = 5

Answer:

r = 5

Step-by-step explanation:

Using Pythagoras' identity in the right triangle ABC

AC² = BC² + AB²

(r + 8)² = r² + 12² ← expand left side using FOIL

r² + 16r + 64 = r² + 144 ( subtract r² from both sides )

16r + 64 = 144 ( subtract 64 from both sides )

16r = 80 ( divide both sides by 16 )

r = 5

The least common multiple of 50, 18 and 32 is 7200.

Step-by-step explanation:

mark brainleist plz

Answer:

LCM = 7200

Step-by-step explanation:

LCM(18, 32, 50) =

LCM(LCM(18, 32), 50)

Working from the innermost parentheses outward:

LCM(18,32) = (18 × 32) / GCF(18,32)

= (18 × 32) / 2

= 576 / 2

= 288

LCM(288,50) = (288 × 50) / GCF(288,50)

= (288 × 50) / 2

= 14400 / 2

= 7200

Therefore,

LCM(18, 32, 50) = 7200

So -2/3 becomes -10/15

and -3/5 becomes -9/15

-9/15 is greater than -10/15

-3/5 is greater than -2/3

Answer:

-2/3 < -3/5

Explanation:

to convert the fractions to equivalent forms, we need to make sure that they have the same denominator (number on the bottom). the lowest common multiple of both 3 and 5 is 15, hence:

-2/3 = -10/15 (×5)

-3/5 = -9/15 (×3)

thus, we can see that -10/15 is smaller than -9/15, and -2/3 is smaller than -3/5.

A) Put 10 marbles in a bag, 8 red and 2 yellow. Draw out a marble at random 100 times, replacing the marble each
time.

B) Divide a spinner into 4 equal parts, labeled 1-4. Spin it 100 times. Let an even number represent Honor Roll and
an odd number represent not on the Honor Roll.

PLEASE REMEMBER TO STATE WHY

Answers

Answer:

A)

Step-by-step explanation:

The problem stated that 20 percent got in honor roll.

The key word in the problem is randomly selected.

Out of a and b, it's simply crossing out one of them.

B doesn't make sense, since if you spun a spinner 100 times, each side would have a probability of 25 percent. And that's if you only used one of the parts as an odd number.

Another way to think of it is that there are 2/10 yellow marbles, and 8/10 red.

2/10=20 percent.

8/10=80
