$1.2 \: cubic \: feet \times \frac{1 \: gallon}{7.48 \: cubic \: feet} \times \frac{8.33 \: pounds}{1 \: gallon}$

= 1.33636364 pounds

I'm not too sure about tons because I don't really know what it is.

The softball team stopped for ice cream after a big game. five 2-scoop cones cost the same as three sundaes. If they bought nine

Savatey [412]

<span>Let the cost of 2-scoop cones be x, and the cost of sundaes be y.
The first statement tells us that 5x = 3y
The second statement tells us that 9x + 6y = 19.95
Then we need to calculate the value of y (the cost of a sundae).
From our first equation, y = 5x/3. Substituting this into the second equation:
9x + 6(5x/3) = 19.95
9x + 10x = 19.95
19x = 19.95
x = 1.05
Substituting back into the first equation: 5(1.05) = 3y
5.25 = 3y
y = 1.75
Therefore the cost of a sundae is $1.75.

Solve x – 7 > –8.

IgorC [24]

Question 1.

x - 7 > - 8

Adding 7 to both sides, we get:

x - 7 + 7 > - 8 + 7

x > -1

Thus the answer to the inequality is option Fourth.

Question 2.

A number exceeds 66. Let that number be x. The number exceeds 66 means that the number is larger than 66. So in form of an expression we can write the inequality as:

x is greater than 66

x > 66

So, option 1st gives the correct answer.

Question 3.

The tiles are square shaped and area of a square can be calculated as the square of its Length.

Area of square = (Length)²

If we are given the Area, we can find the length as:

Length = $\sqrt{Area}$

For Tile A, the length will be:

$Length= \sqrt{9}=3$
So length is a Rational number

For Tile B, the length will be:

$Length= \sqrt{25}=5$
So length is a Rational number

For Tile C, the length will be:

$Length= \sqrt{34}$
So, Length is not Rational.

For Tile D, the length will be:

$Length= \sqrt{76}$
Length is not Rational

Thus, the lengths of Tile A and Tile B are rational only.

Therefore, the correct answer is 1st option
