Math question highschool

Vlad1618 [11]

Answer:

3589.85763 meters

Step-by-step explanation:

Essentially, we must have e^(-0.00012h) = 0.65 since 0.65 = 65%

Taking natural log of both sides, we get

-0.00012h = -0.430782916

0.00012h = 0.430782916

h = 3589.85763

Determine which factors below can be the dimensions of a rectangle with an area of .

Alenkinab [10]

Answer:

Step-by-step explanation:

Area of a rectangle is length * width.

The question asks which of the following (length * width) will give the expression for area...

We multiply each, and whichever is equal to the expression for area given, is the answer. We use the distributive property to expand.

Distributive property is $a(b+c)=ab+ac$

$(3x-7)(4x+9)\\=12x^2+27x-28x-63\\=12x^2-x-63$

This is not the answer.

$(3x+7)(4x-9)\\=12x^2-27x+28x-63\\=12x^2+x-63$

We don't need to do more because B is equal to the expression of area given.

B is the correct answer.

There are 900 toothpicks in a regular-sized box. If a jumbo box is made by tripling all the dimensions of the regular-sized bo

Colt1911 [192]

When you triple the height of the box, it can hold (900 x 3) = 2,700 pieces.

Then triple its length, and it can hold (2,700 x 3) = 8,100 pieces.

Then triple its width, and it can hold (8,100 x 3) = 24,300 pieces.

When you triple the dimensions of a 3D object, it has 27 times its original volume. (900 x 27) = 24,300 .
