Dominik [7]2 years ago
8 0

Answer:

A. 12.25 tons

Step-by-step explanation:

We will let x represent the amount required to cover the entire wall.

We can divided 2/5 by 5/6 to solve for x

2/5 divided by 5/6=x

When you divide by a fraction, you can always multiply by the reciprocal (flipped number).

Our new equation is:

2/5·6/5=12/25

Translate 2 3 y − 9 < y + 1 into a sentence. Nine than two-thirds of number is less than the number .
vovangra [49]

Answer:

The given inequality is

\frac{2y}{3}  - 9 < y + 1

Let y be a Real number such that 9 less than two third of that number is less than  one added to that number.

We can find solution of the inequality also

1. keeping variable on one side and constant on another side, which gives

→y - \frac{2y}{3} > -9 -1

→\frac{y}{3} > -10\\\\y> -30

The distance be<br> Find the distance between P and Q
Lelu [443]

Answer:

  10

Step-by-step explanation:

The distance formula is useful.

  d = √((x2 -x1)^2 +(y2 -y1)^2)

  d = √((7 -1)^2 +(12 -4)^2) = √(6^2 +8^2) = √(36 +64) = √100

  d = 10

The distance between P and Q is 10.

<em>Additional comment</em>

You may recognize the run : rise ratio of 6 : 8 = 3 : 4. This suggests a 3-4-5 right triangle with a scale factor of 2. If you're familiar with that Pythagorean triple, you can write down the answer as soon as you see the rise and run numbers.

Two factors of 24 add up to 11 what are they
allsm [11]
x*y=24
x+y=11
y=24/x
y=11-x
24/x=11-x
11x-x^{2} =24
- x^{2} +11x-24=0
(-x+8)(x-3)=0
-x+8=0   x-3=0
x=8 or 3
Your factors are 8 and 3.
