Answer:

x=67º

Step-by-step explanation:

First since the supplementary angle next to 157º is in the triangle, we can find that. 180-157 = 23. Then we can use triangle angle sum theorem to find x. 180-(23+90) = 67º

Answer:

Complementary, x=10

Step-by-step explanation:

Complementary angles mean they add up to 90 degrees.

So 29+(6x+1)=90.

30+6x=90

D

Step-by-step explanation:

A. 9x9 = 81

B. 2x2x2x2x2 = 32

C. 10x10 = 100

D. 5x5x5x5 = 625

Answer:

5⁴ has the greatest value

Step-by-step explanation:

9² = 9 x 9 = 81

2⁵ = 2 x 2 x 2 x 2 x 2 = 32

10² = 10 x 10 = 100

5⁴ = 5 x 5 x 5 x 5 = 624

Therefore, 5⁴ has the greatest value!

Answer:

r will be half of your diameter so 11 divided by 2 = 5.5 is your new radius.

To find surface area we use the basic formula:

4πr^2

4 x 3.14 x 30.25(radius squared, 5.5 x 5.5 = 30.25) = 379.94 ft^2 is your surface area

Answer:

r = 4units

Step-by-step explanation:

The standard foem of equation of a line is expressed as;

(x-a)² + (y-b)² = r²

r is the radius

Compare with the given equation (x - 2)^2 + (y + 1)^2 = 16

r² = 16

r = √16

r = 4

Hence the radius of the circle is 4

Answer:

Between - groups variance

Step-by-step explanation:

From the question we see that the college freshmen are assigned to one of the three given groups. This means that they are exposed to different experimental conditions and thus it means that the variation differs as a result of different experimental conditions between the groups.

Thus, these differences reflect between - group variance.

The abbreviation CD stands for "Compact Disc."

A compact disc is a small, portable, round disc that is used for storing and playing back digital audio, video, and other types of data. It was introduced in the early 1980s as a replacement for vinyl records and cassette tapes.

A CD is made up of a polycarbonate plastic layer that is coated with a reflective metal layer and protected by a clear plastic layer. Information is stored on the disc in the form of tiny pits and lands that are read by a laser beam in a CD player or computer CD-ROM drive.

CDs have a storage capacity of up to 700 MB, which allows for around 80 minutes of audio or several hours of compressed video. They are commonly used for storing music albums, software programs, and other types of multimedia content.

In addition to audio CDs, there are also CD-ROMs (read-only memory), CD-Rs (recordable), and CD-RWs (rewritable). CD-ROMs are pre-recorded discs that cannot be modified, while CD-Rs and CD-RWs can be burned or written with data by the user. CD-Rs can only be written once, while CD-RWs can be erased and re-written multiple times.

Overall, the abbreviation CD refers to the Compact Disc, a versatile medium for storing and playing back digital data.

Answer:

C)

(x, y) → (x – 8, y)

Answer:

x > -2

Step-by-step explanation:

-3x + 2 < 8

our goal is to isolate the x

subtract two from both sides

-3x < 8 - 2

- 3x < 6

divide both sides by -3

flip the sign because we divided by a negative number

x > -2

Step-by-step explanation:

Answer:

8 seconds

Step-by-step explanation:

Given :

h(t) = -16t2 + initial height

Initial height = 1024 feets

By the time it hits the ground, h(t) = 0

Equation becomes :

0 = - 16t² + 1024

Solve for t

-16t² = 1024

t² = 1024 / -16

t² = 64

t = √64

t = 8

Hence, it will take 8 seconds

Answer: #444

Step-by-step explanation:

First find the original selling price of the article.

When sold for #372 the profit was 24%. Assume the original price is x.

372 = x + 24% * x

372 = 1.24x

x = 372 / 1.24

= #300

If he wanted to make a profit of 48% he should have sold for:

= Original price + (original price * 48%)

= 300 + (300 * 48%)

= #444

the following could define the function g: 20. (2.5)ˣ = g(x)

correct option: B

Exactly one element of Y is assigned to each element of X in a mathematical function from a set X to a set Y. Both the set X and the set Y are referred to as the function's domain and co-domain, respectively. The basic conception of functions was the relationship between fluctuating quantities and other variables.

h(x) = 20. 4ˣ    (0, 20)

here, g(x) passes through the point (0, 20)

thus, g(x) = 20. aˣ

when x > 0, f(x) < g(x) < h(x)

hence a < 4

so, 20. (2.5)ˣ - 10. 2ˣ > 0

or, 20. (2.5)ˣ = g(x)

correct option: B
