a) Jodi's car traveled 38 miles per gallon of gas. We know this because by dividng the amount of miles traveled by number of gallons Jodi has in her car we can find how many miles she travels per gallon of gas.

So our equation would be 456 / 12 = 38

b) The cost per gallon of gas was $3.74. We can find this answer by dividing how much she paid ($44.88) by how many gallons she bought (12).

So our equation would be 44.88 / 12 = 3.74

The product of two integers is 112. One number is four more than three times the other. Which of the following equations could b

shepuryov [24]

Answer:

The equations could be used to find one of the numbers is, $3a^2 + 4a =112$

Step-by-step explanation

Let two integers be a and b.

As per the given statement:

The product of two integers is 112.

⇒ $ab =112$ ......[1]

Also, One number is 4 more than three times the other.

⇒b = 3a +4 ......[2]

Now substitute equation [1] in [2] we get

$a(3a+4) =112$

Using distributive property i.e, $a \cdot (b+c) = a\cdot b + a\cdot c$

$(a)(3a)+ 4a = 112$

Simplify:

$3a^2 + 4a =112$

therefore, the equation that could be used to find one of the numbers is;

$3a^2 + 4a =112$

The radius of the cone is 1.25 inches, and its height is 2.75 inches. If the diameter of the bubble gum ball is 0.5 inches, what

nasty-shy [4]

<h2>Explanation:</h2><h2></h2>

The volume of a cone can be found as:

$V=\frac{1}{3}\pi r^2 h \\ \\ \\ Where: \\ \\ V:Volume \\ \\ r:radius \ of \ base \\ \\ h:height$

Given the radius and height, we can find the volume of the cone:

$V=\frac{1}{3}\pi r^2 h \\ \\ V=\frac{1}{3}\pi (1.25)^2(2.75) \\ \\ V=\frac{1}{3}\pi(1.5625)(2.75) \\ \\ V\approx 4.5in^3$

The volume of a sphere is:

$V=\frac{4}{3}\pi r^3 \\ \\ \text{Each gum ball has a diameter of 0.5in, so the radius is:} \\ \\ r=\frac{0.5}{2}=0.25in$

So, for each gum ball the volume is:

$V=\frac{4}{3}\pi r^3 \\ \\ V=\frac{4}{3}\pi (0.25)^3 \\ \\ V=0.065in^3$

Therefore, the he closest approximation of the volume of the cone that can be filled with flavored ice is:

$4.5-0.065=4.43in^3$

Conclusion: The volume of the cone that can be filled with flavored ice is 4.43 cubic inches.
