2 pears cost as much as 3 apples.if the total cost of 2 pears and 3 apples is $2,what is the cost of 12 apples?

1 answer:

5 0

The cost of 12 apples is $<span>4</span>

Here is how I got my answer:

2 pears = 3 apples

The cost of 2 pears AND 3 apples. we know three apples is equal to another 2 pears so basically its 4 pears are 2 dollars. Or 6 apples are 2 dollars.

using this information we can conclude that
Every 3 apples is a dollar

so we divide 3 by 12

4, so our answer is $4.

The perimeter of a rectangular construction site is 124 meters. The width is eight meters more than 5 times the length. Find the

tresset_1 [31]

Answer:

The perimeter of a rectangle is the sum of both lengths and both widths, which is equal to 54 meters. Let's call Length L and Width W.

The question is saying this: L = 3 meters + 3(W). We have 2 variables, which means we need at least 2 equations to solve. So far we have one, our second equation is from the perimeter.

2 lengths + 2 Widths = 54. Now, it's just a plug and chug.

2(3 + 3W) + 2W = 54.

6 + 6W + 2W = 54

8W = 48

W=6

L = 3 + 3(6) = 21

To double check: 2(21) + 2(6) = 42 + 12 = 54

The Width is 6 meters, and the Length is 21 meters.

Solve for the value of x: x/2 + x/3 = 2x/5 + 3 , also I need a very thorough explanation for this.

Alona [7]

Answer:

$x=\frac{90}{13} .$

Step-by-step explanation:

$\frac{x}{2} +\frac{x}{3} =\frac{2x}{5} +3;$

$30*(\frac{x}{2} +\frac{x}{3} )=30*(\frac{2x}{5} +3);$

15x+10x=12x+90; ⇔ 13x=90;

$x=\frac{90}{13}.$

Given that X ~ N(120, 35). We survey samples of 25 and are interested in the distribution of X-bar. Find the z-score associated

lubasha [3.4K]

Answer:

Option c -2.8571

Step-by-step explanation:

z-score are calculated as

$z=\frac{xbar-mean}{\frac{S.D}{\sqrt{n} } }$ .

We are given that mean=120 and standard deviation=S.D=35 as X~N(120,35).

Sample size=n=25.

We have to find z-score for x-bar=100. So,

z-score=[100-120]/[35/√25]

z-score=[-20]/[35/5]

z-score=-20/7

z-score=-2.8571.

Thus, the z-score associated with x-bar = 100 is -2.8571.
