Answer: Yes, it will be enough.

Step-by-step explanation:

I will answer this in English:

We have 27 students and 81 units, we want to give 3 units to each student.

This is only possible if the quotient betwen 81 and 3 must be bigger than 27.

Lets do it:

81/3 = 27

So we have exactly enough for the 27 students.

A trough is filled with water. The trough holds 315 gallons. Each cubic foot of water contains about 7.5 gallons. The trough is
elena55 [62]

Answer:

The height of the trough is about 1.5 ft

Step-by-step explanation:

If each cubic foot of water contains about 7.5 gallons.

Then; 315 gallons is about \frac{315}{7.5}=42ft^3

Let h be the height of the trough, then

7\times 4\times h=42

This implies that;

28h=42

Divide both sides by 28 to get:

h=\frac{42}{28}

\therefore h=1.5

The height of the trough is about 1.5 ft

What is the answer of this question?
NeX [460]
X =/= 4, -4

Explanation: if you replace the values of “x” with either “4” or “-4”, then one or more of the denominators will equal 0. Since you can not divide by zero, “X =/= 4, -4” is the correct solution.

I got 6 wrong and I don’t understand how to do number 9 can someone please help?<3
Fudgin [204]

Answer: you got it right

Step-by-step explanation:

Convert the problem to an equation using the percentage formula: P% * X = Y

P is 35%, X is 140, so the equation is 35% * 140 = Y

Convert 35% to a decimal by removing the percent sign and dividing by 100: 35/100 = 0.35

Substitute 0.35 for 35% in the equation: 35% * 140 = Y becomes 0.35 * 140 = Y

Do the math: 0.35 * 140 = 49

Y = amount of discount= 49

So 35% of 140 is 49

140-49= sale price= 91
