Answer:

2 inches per hour

Step-by-step explanation:

2 1/2 hours is equivalent to 150 minutes.

Set up a proportion; let x equal inches of rain

$\frac{5}{150}$ = $\frac{x}{60}$

Cross multiply -> 150x=300

Divide both sides by 150 to get -> x=2

Four less than six times a number is the same as eight times the number, x, increased by 12

Crazy boy [7]

Answer:

Step-by-step explanation:

let the number be x

4-6x=8x+12

subtract 4 on both sides

-6x=8x+8

subtract 8x on both sides

-14x=8

x=-8/14

x=0.57142857142

100 POINTS! I REALLY NEED TO GET THIS CORRECT! Factor the quadratic trinomial.

Assoli18 [71]

The factors of the equation $x^2-3x-18$ are $(x-6)(x+3)$

Step-by-step explanation:

We need to factor the quadratic trinomial. $x^2-3x-18$

We will do factorization by braking the middle term such that adding those number we get middle term (-3x) and multiplying those numbers we get (-18x^2)

Solving:

$x^2-3x-18\\=x^2-6x+3x-18\\=x(x-6)+3(x-6)\\=(x-6)(x+3)$

So, the factors of the equation $x^2-3x-18$ are $(x-6)(x+3)$

What is the approximate volume of the tube? Round to the

vladimir2022 [97]

Answer:

The approximate volume of the tube is 1,005 cm³

Step-by-step explanation:

To find the volume of the tube, we will follow the steps below:

First, write the formula for calculating the volume of a cylinder

volume of a cylinder = πr²h

where r is the radius and h is the height of the cylindrical cardboard tube

from the question given, height is equal to 20 centimeters and diameter = 8 centimeters but diameter = 2r, this implies that r = d/2 hence radius r =8/2 = 4 centimeters

π is a constant and is ≈ 3.14

we can now proceed to insert the values into the formula

volume of a cylinder = πr²h

≈ 3.14 × 4²× 20

=3.14 × 16× 20

≈1,005 cm³ to the nearest whole cubic centimeter.

The approximate volume of the tube is 1,005 cm³

An exam consists of 4 true/false questions and 6 multiple-choice questions with a, b, c, d, and e as

Ivahew [28]

Answer:

Step-by-step explanation:

To answer this problem, you break the answer into two parts, one part for the true/false section and another part for the multiple-choice section.

True/False

There are 2 ways to answer each of the 4 true/false questions, T or F.

The number of ways to answer the trur/false section is $2\times2\times2\times2=2^4=16$ .

Multiple-Choice

There are 5 ways to answer each question so the number of ways to answer this section is

$5\times5\times5\times5\times5=5^6=15625$

You can answer the T/F section in 16 ways and the M/C section in 15625 ways, so the entire exam can be answered in

$16\times15625=250000$ ways!

It's mind-boggling that only 1 of those ways gets a score of 100%!
