Find b
Round to the nearest tenth:
c
8 cm
820
550
b
b = [? ]cm

Answer:

a = 93°, b = 120°, c = 150°

Step-by-step explanation:

b + 36 = 78 × 2 => b + 36 = 156 => b = 120°

87 × 2 - b = the minor arc between a and 78

=> 174 - 120 = 54

54 + b + 36 + c = 360

=> 54 + 120 + 36 + c = 360

=> c = 150°

(c + 36) ÷ 2 = a

=> (150 + 36) ÷ 2 = a

=> a = 93°

Answer:

The sum of alternating angle end up to 180 degress

Answer:

b=2

Step-by-step explanation:

To get slope given two points, take the difference of the y values and divide it by the difference of the x values.

(This is also called change in y over change in x, or rise over run)

b-(-2)/2-1=4

b+2/1=4

b+2=4

b=2

Answer:

1680.

Step-by-step explanation:

30 * 56

Answer:

6/7

Step-by-step explanation:

The constant rate of change is also know as the slope of the expression

Given

24x-28y=14

Write in standard form y = mx+c

m is the slope

24x-28y=14

-28y = -24x + 14

y = -24x/-28 + 14/-28

y = 6/7 x - 1/2

Compare

mx = 6/7 x

m = 6/7

Hence the  constant rate of change is 6/7

Answer:

[tex]\\\\\frac{P^3 \ + \ 1}{P^3} = 0[/tex]

Step-by-step explanation:

Given;

[tex]\frac{P-1 }{P} = 2\\\\From \ the \ equation \ above \ we \ determine \ the \ value \ of \ p \ as \ follows;\\\\P-1 = 2P\\\\P-2P = 1\\\\-P = 1\\\\P = -1[/tex]

[tex]Now\ solving \ the \ given \ question;\\\\\frac{P^3 \ + \ 1}{P^3} \\\\Substitute \ the \ value \ of \ "P" \ into \ the \ equation;\\\\\frac{P^3 \ + \ 1}{P^3} = \frac{(-1)^3 \ + \ 1}{(-1)^3} = \frac{-1 \ + \ 1}{-1} = \frac{0}{-1} = 0[/tex]

Answer:  B: 0.81 miles

Step-by-step explanation:

The find the total distance, you must look for firs the missing side. To get use the formula that is derived from the Pythagorean theorem which states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

The formula for this is: a^2 + b^2 = c^2

So let the first side or a be .19

and the second side be .28

and now we are looking for c which is the missing side

.19^2 + .28^2 = c^20.0361 + 0.784 = .1145

get the square root of .1145

√.1145 = it is approximately 0.34

get the total distance by adding three sides

= .34 + .19 + .28

= 0.81

Answer:

C. 12

Step-by-step explanation:

Find the percentage of him drawing a blue marble.

4/10 = 0.4

He has a 40% chance of picking blue.

Find 40% of 30.

12

He would draw a blue marble around 12 times.

Answer:

C

Explanation:

So in the bag, there are 10 marbles, and 4 of them are blue, so if he drew from the bag 10 times, we can assume the fraction:

4/10

Next, we see that the denominator, or the number times Cade is drawing from the bag is 30, which makes us multiply most sides of the fraction by 3:

12/30

So I would say 12/30, but again, he wouldn't draw a blue exactly 4 times, and it may be more or less, so either 8/12....

Answer:

125 cups can hold  49.5 liters of water.

Step-by-step explanation:

The volume of the cup will tell how much water is needed to fill each cup.

The volume of the cup can be determined by the formula

V= base area* height

V= πr²* h

V= 22/7 (3)² (14)

V= 396cm³

125 cups can hold 125 * 396 cm³= 49500cm³

But 1 cm³= 0.001 Liters

Therefore = 49500*0.001= 49.5 liters

125 cups can hold  49.5 liters of water.

Answer:

C. Zero

Step-by-step explanation:

The solution of the system of equations would be the point where they intersect, but since these lines are parallel, they will never intersect, so therefore there are zero solutions.

Answer:

u = -3

Step-by-step explanation:

Solve for u:

u - 5 = -8

Hint: | Isolate terms with u to the left hand side.

Add 5 to both sides:

u + (5 - 5) = 5 - 8

Hint: | Look for the difference of two identical terms.

5 - 5 = 0:

u = 5 - 8

Hint: | Evaluate 5 - 8.

5 - 8 = -3:

Answer: u = -3

Answer:

1880

Step-by-step explanation:

multiply 47 and 40

Note that the formula for the circumference of a circle is πd, while the formula for the area of a circle is πr².

π≈3.14

A. C=πd

Simply plug in the numbers into the formula.

Diameter=Radius*2

17*2=34

C=34(π)

B. (π)(5²)

Plug in the numbers into the formula. Remember that half of the diameter is the radius.

C.  (π)(4.5)

There are two possible formulas that could be used to calculate the circumference of a circle: πd and 2πr.

The expression above is simply multiplying the circle's radius times pi. Therefore, it is not a method that could be used to find the circumference of a circle.

D. (π)(6.5²)

Remember that the formula for calculating the area of a circle is πr².

Half of the diameter is 6.5 (13.5/2=6.5). 6.5 cm. is the radius. Now just plug the numbers into the formula.

(π)(6.5²)

Therefore, the last answer choice is the correct answer.

Answer:

Hello again! x = 85

Step-by-step explanation:

Because triangles are 180 degrees and

68 + 27 = 95 and 180 - 95 = 85 so our missing angle is 85 hope this helps!
