Answer:

measure of angle C = 18°

c = 2.47

a = 7.61

Step-by-step explanation:

Make sure your calculator is in degree mode.

Angle A measures 72°, so angle C measures 18° (Angles A and C are complementary angles, so their sum is 90°).

[tex] \sin(18) = \frac{c}{8} [/tex]

[tex]c = 8 \sin(18) = 2.47[/tex]

[tex]a = 8 \cos(18) = 7.61[/tex]

Answer:

C

Step-by-step explanation:

Becuase 68 is closer to c than b

Answer:

The value of x is equal to 30.

Step-by-step explanation:

Let's define what are 2 equations are:

Since we are dealing with a straight line, the line's angle will always equal 180°.

Since the 2 angles must add up to 180°, then they must be supplementary angles.

We can set up our equation to solve for x:

This equation states that the 2 angles, given in formulas, must be equal to the angle of the line.

We can now solve this equation and get a value of x:

∴ we have found the value of x to be equal to 30.

Flaws:Total Box

Plug in current values

4:22

44/22 = 2

Multiply the ratio by 2

8:44

8 boxes would be flawed.

Answer:

8

Step-by-step explanation:

There are 2 ways to do this I have seen.

1. 4/22 will get you .18, you can then multiply that by 44 and get 8

2. 22*2 is 44 so you can assume the number of flaws will also be the same amount multiplied (a multiple of 2) and you will get 8

The trinomial, 3x² + 13x – 10, when factored will give you: (3x + 10)(x - 1).

To factor a trinomial, we need to find two factors that would give us the exact trinomial when expanded.

Given, 3x² + 13x – 10:

3x² -3x + 10x - 10

(3x² - 3x) + (10x - 10 )

3x(x - 1) +10(x - 1)

Answer:

a1=2 and r=-1

Step-by-step explanation:

"A geometric series is a series with a constant ratio between successive terms".

Here, we can observe that the first term 'a' is '2'.

And the common ratio 'r' =

Therefore, the first term 'a' is 2 and common ratio 'r' is '-1'.

First term, a, is 2.  Next term, -2, is the product of 2 and -1 and is -2.  Next term, 2, is the product of -2 and -1.  Thus, the first term, a, is 2 and the common ratio, r, is -1

60^2 + b^2 = 100^2

3600 + b^2 = 10,000

-3600              -3,600

b^2 = 6,400

Square root both sides of the equation

b = [tex]\sqrt{6400}[/tex]

[tex]\sqrt{6400}[/tex] = 80

The length of side a is 80 m

Answer:

One

Step-by-step explanation:

For unique triangles with 3 sides, the sum of the two shorter sides must be greater than the third side.

Shorter sides:  6 cm and 2.5 cm

Longer side:  6.5 cm

6 + 2.5 = 8.5

As 8.5 > 6.5 this is a unique triangle

As the side lengths are fixed, only one unique triangle can be formed.

Answer:

84 inches

Step-by-step explanation:

It is the perimeter.

Koda needs 84 inches of ribbon to put it around the edge of the board.

A classroom board is 24 inches wide and 18 inches tall, Koda s putting ribbon along the outside edge of the board.

Perimeter is the measure of the figure on its circumference.

Here,
length = 24 inch
width = 18 inch
The perimeter of the board, = 2 {length  + width]
                                             = 2 [24 + 18]

                                             = 84

Thus, Koda needs 84 inches of ribbon to put it around the edge of the board.

The interest rate would be 2.5%

Answer: Concave down

Explanation:

An example is shown below. We have the concave down parabola [tex]y = -x^2+7[/tex] marked in red. The trapezoidal sum is in blue. The three trapezoids combine to something just a bit smaller than the true area under the curve from x = -2 to x = 1. Therefore, this trapezoidal sum is an underestimate of the true area under the curve.

Every part of each trapezoid is completely below the red curve. In other words, no part of the blue pieces spill above the parabola.

The volume of a sphere with radius 8 units is 2143.57 units³

What is a Sphere?

A sphere is symmetrical, round in shape. It is a three dimensional solid, that has all its surface points at equal distances from the center. It has surface area and volume based on its radius. It does not have any faces, corners or edges.

The Surface Area of a Sphere = 4πr²

The Volume of a Sphere = ( 4/3 ) πr³

where r is the radius of the sphere

Given data ,

Let the volume of the sphere be represented as A

Now , the value of A is

Let the radius of the sphere be r

The value of r = 8

Now , the formula to calculate the volume of the sphere is

Volume of a Sphere = ( 4/3 ) πr³

Substituting the values in the equation , we get

Volume of a Sphere = ( 4/3 ) x 3.14 x 8 x 8 x 8

Volume of a Sphere = ( 4/3 ) x 3.14 x 512

Volume of a Sphere = ( 4/3 ) x 1607.68

Volume of a Sphere = 2143.57 units³

Therefore , the value of A is 2143.57 units³

Hence , the volume of the sphere is 2143.57 units³

Answer:

1/32

Step-by-step explanation:

We can break this question down. If we had 1 person and they are right-handed, the probability is 1/2 because they are either left-handed or right-handed. Knowing that, we can multiply the probability of having 1 person being right-handed 5 times because there are 5 people in the question.

1/2 × 1/2 × 1/2 × 1/2 × 1/2 = 1/(2⁵) = 1/32

Therefore, the probability of randomly selecting 5 people who are right-handed is 1/32.
