Mr. and Mrs. Galloway are planning to build a new fence around their garden. They are comparing the different measurements for t
Romashka [77]

Answer:

5 1/8 feets

Step-by-step explanation:

Given that:

PLAN A:

Length of post = 4.25 feets

Post must be 7/8 feets below the ground

Height of fence in PLAN A :

Converting 4.25 feets to decimal :

4.25 feets = 4 feets + 0.25 feets

0.25 feets = 1/4 feets

4 + 1/4 feets = 4 1/4 feets

4 1/4 feets + 7/8 feets

17 /4 feets + 7 /8 feets = [(34 + 7) / 8] feets

[(34 + 7) / 8] feets = 41/ 8 feets

41 / 8 feets = 5 1/8 feets

First answer gets brainly, please use an explanation too.
vaieri [72.5K]

Answer:

Ezra will have 5 ounces of water leftover

Step-by-step explanation:

I first divided 4,005 by 16 to get 250.3125, which I rounded to 250. Then I multiplied 250 by 16 to get how many ounces Ezra used, which is 4,000. Then I subtracted that value from how many ounces she had to get how many she had leftover.

Twelve is no less than the sum of a number n and 3
lawyer [7]

In the figure BE||CD solve for x. Show work
nataly862011 [7]

Answer:

The value of x = 15.

Step-by-step explanation:

Given:

BE || CD

AE = 9

ED = 6

AB = x

BC = 10

To Find;

AB = x = ?

Solution:

BE || CD ......................{Given}

Basic Proportionality Theorem:

If a line is parallel to a side of a triangle which intersects the other sides into two distinct points, then the line divides those sides in proportion.

i.e

\frac{AE}{ED} =\frac{AB}{BC}...........{Basic Proportionality Theorem}

Substituting the given values we get

\frac{9}{6} =\frac{x}{10}\\\therefore x = 10\times \frac{9}{6}\\\therefore x = \frac{90}{6}\\\therefore x = 15

The value of x = 15.
