A store sells toys in bulk. It sells wooden blocks for $5 a pound and plastic bricks for $10

steposvetlana [31]

Answer:

4 pounds of wooden blocks and 6 pounds of plastic bricks should be used.

Step-by-step explanation:

Let w = wooden block

Let p = plastic bricks

<u>Given the following data;</u>

Price of wooden block per pounds = $5

Price of plastic brick per pounds = $10

*Translating the word problem into an algebraic equation*

For the 10-pound mixture;

$w + p = 10$ .........equation 1

For the $80 mixture;

$5w + 10p = 80$ ..........equation 2

Solving the linear equation by using the substitution method;

Making w the subject in equation 1:

$w = 10 - p$ .......equation 3

Substituting "w" into equation 2;

$5(10 - p) + 10p = 80$

Simplifying the equation, we have;

$50 - 5p + 10p = 80$

$50 + 5p = 80$

Rearranging the equation, we have;

$5p = 80 - 50$

$5p = 30$

$p = \frac {30}{5}$

p = 6 pounds (For the plastic brick).

To find w;

Substituting "p" into equation 3;

$w = 10 - 6$

w = 4 pounds (For the wooden block).

Can someone help assist me on this Honors Algebra 2 Problem? Challenge Problems #6. The distance from a point on the curve y=√x

ahrayia [7]

Answer: (0, 0) & (3, √3)

<u>Step-by-step explanation:</u>

Since we need a distance of 2, I graphed y = √x and then drew a circle at center (2, 0) and radius of 2 to see where they intersect.

The coordinates of intersection can be determined by solving a system of equations.

Equation 1: y = √x

Equation 2: (x - 2)² + y² = 2²

I will use the Substitution method with Equation 2 to solve for x:

(x - 2)² + (√x)² = 2² substituted y with √x

x² - 4x + 4 + x = 4 expanded binomial

x² - 3x + 4 = 4 added like terms

x² - 3x = 0 subtracted 4 from both sides

x(x - 3) = 0 factored

x = 0 x - 3 = 0 applied Zero Product Property

x = 3

Next, solve for y using Equation 1:

x = 0: y = √0 = 0

x = 3: y = √3

Coordinates of intersection are: (0, 0) & (3, √3)

Luke mowed a lawn today to earn some extra money. He spent $2.10 on fuel and $4.45 on lunch. He charged $13.50 to mow the lawn.

liberstina [14]

If you add his expenses, $2.10 + $4.45 you’ll get that Luke spent $6.55 today.

Then subtract his expenses by how much he made for mowing the lawn, $13.50 - $6.55 =

Your answer is A. $6.95

How can a triangular prism have a greater volume than a rectangular prism?

son4ous [18]

Answer:

Step-by-step explanation:

Assume that the two prisms have bases of equal area.

Then the volume of the rectangular prism is V = (base area)(height).

The volume of the triangular prism is V = (1/3)(base area)(height)

We could compare the two volumes by creating the ratio inequality

(1/3) (base area)(t-height)

------------------------------------------

(base area)(r-height)

The triangular prism will have the greater volume for (1/3)((t-height) > r-height.
