Mathematics

ANEK [815]3 years ago

1) Let Sean=x and Tyrone=y. But we want to get what Sean earns and what Tyrone earns in terms of one variable so we say that Tyrone=x-4.5 (beacuse he makes $4.50 per hour less than Sean).   2) Now set up the equation: 8 hours time x plus 8 hours times x-4.5 equals 284 OR
8x+8(x-4.5)=284   3) Solve for x  8x+8(x-4.5)=284 8x+8x-36=284 16x=320 x=20   So Sean makes $20 per hour and Tyrone makes $15.50 per hour

crimeas [40]

<u>Answer: </u><em><u>h=80 is the final answer. *The answer must be have a positive sign.*</u></em>

Explanation:

<em><u>Switch sides of an equation.</u></em>

<em><u>3/4h=60</u></em>

<em><u>multiply by 4 both sides of an equation.</u></em>

<em><u>4*3/4h=60*4</u></em>

<em><u>simplify.</u></em>

<em><u>3h=240</u></em>

<em><u>divide by 3 both sides of an equation.</u></em>

<em><u>3h/3=240/3</u></em>

<em><u>simplify.</u></em>

<em><u>240/3=80</u></em>

<em><u>80*3=240</u></em>

<em><u>3*80=240</u></em>

<em><u>240/80=3</u></em>

<em><u>h=80</u></em>

<em><u>Hope this helps!</u></em>

It is a solid shape that contains lateral surface and two circular bases which are parallel and congruent.
ad-work [718]

Answer:

B (cylinder)

Step-by-step explanation:

Two <u>circular</u> bases which are parallel and congruent :

This basically means that the shape contains a circular base (supposedly the bottom), but since it has two bases, its on the top and the bottom. Because it's congruent, the bases are both equal in shape and size. It is also parallel as well, in which the bases have the same distance between them.

The cube doesn't have any circular bases.

The sphere doesn't have any faces, nor edges.

A cone has a circular base, but it doesn't have two.

A cylinder has two circular bases, as well as they are parallel and congruent.

So, your answer is B (cylinder).

Hope this helped !

Sometimes data do not follow a normal distribution and are pulled toward the tails of the curve. When this occurs, it is referre
Airida [17]

Answer:

When the tail is pulled toward the right side, it is called a positively skewed distribution

Step-by-step explanation:

When the tail is pulled toward the right side, it is called a positively skewed distribution; when the tail is pulled toward the left side of the curve it is called a negatively skewed distribution (Watzlaf 2016, 361-362).

Generally the right side of a function is reserved for positive variables and the left side is used to represent negative variables, therefore when a function is pulled to the right is considered to be Positively skewed
