A store sells toys in bulk. It sells wooden blocks for $5 a pound and plastic bricks for $10
a pound. How many pounds of wooden blocks and plastic bricks should be used to make a
10-pound mixture that would sell for $80?

Answers

Answer 1

9514 1404 393

Answer:

6 # plastic bricks4 # wooden blocks

Step-by-step explanation:

Let p represent the number of pounds of plastic bricks in the mix. Then the number of pounds of wooden blocks is (10-p), and the total cost is ...

  10p +5(10-p) = 80

  5p = 30 . . . . . . . . . subtract 50

  p = 6 . . . . divide by 5; there are 6 pounds of plastic bricks in the mix

4 pounds of wooden blocks and 6 pounds of plastic bricks should be used to make a 10-lb mix worth $80.

solve for z: -4 - (z - 6) = 12

Answers

Answer:

z = -10

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define equation

-4 - (z - 6) = 12

Step 2: Solve for z

Distribute negative:                              -4 - z + 6 = 12Combine like terms:                             -z + 2 = 12Subtract 2 on both sides:                    -z = 10Divide -1 on both sides:                        z = -10

Step 3: Check

Plug in z to verify it's a solution.

Substitute:                    -4 - (-10 - 6) = 12Subtract:                       -4 - (-16) = 12Simplify:                        -4 + 16 = 12Add:                               12 = 12

Here we see that 12 does indeed equal 12.

∴ z = -10 is a solution of the equation.

Answer:

z = -10

Step-by-step explanation:

-4 -(z+6)=12

2-z=12

-z =12-2

ans= z = -10

Answer:

The coordinates of mage of L(5, 10) will be: (11, 3)

So, the 4th (last) option is correct.

Step-by-step explanation:

As we know that Translation means how much a point is moved to the left/right and up/down.

Given the translation maps the point J(1, 4) onto K(7, -3).

As the x-coordinate of the image point K(7, -3) is 7 which is 6 units right to the original point J(1, 4).

Also, the y-coordinate of the image point K(7, -3) is -3 which is 7 units down to the original point J(1, 4)

so it means the translation basically implies that

(x, y) → (x + 6, y - 7)

Hence, the coordinate of the image of L(5, 10) can also be determined by

using the same rule.

(x, y) → (5 + 6, 10 - 7) = (11, 3)

Therefore,  the coordinates of mage of L(5, 10) will be: (11, 3)

So, the 4th (last) option is correct.

Is the domain of the function represented by the data shown in the graph discrete or continuous?​

Answers

Answer:

continuousdistance traveled by walking

Step-by-step explanation:

You can draw the graph without lifting your pencil, so it is "continuous."

Rows, drinks, and books are all things that are counted. That is, their number takes on discrete values.

Time, on the other hand, is continuous--able to take on any value.

The graph best models distance as a function of time.

Lines l and k are parallel to each other. A=120 degrees. and C=80 degrees. What is the number of degrees in B??
100 points

Answers

Answer:

B = 160°

Step-by-step explanation:

This is how I solved it (I hope the explanation isn't too confusing):

Since L and K are parallel, I drew a straight line from A to B. By doing this, I'm making a triangle: ΔABC

Then I solved for the angles of the triangle. First, we are given that ∠C = 80° and ∠A = 120°. Although, when I drew the vertical line from A to B, it made a 90° (see attachment).

So what we basically did was break ∠A into two parts: an angle inside ΔABC and one outside. To find the interior angle, simply subtract 90° from 120° to get 30°.

There are 180° in a triangle, so add the two interior angles you know:

30° + 80° = 110°

Then subtract 110° from 180° to find the final interior angle which is:

180° - 110° = 70°.

To find the measure of angle B, you must add all of the parts together, so the 90° outside angle and the 70° interior angle:

90° + 70° = 160°

Carlos is packing bags for treats at a party. Every bag has exactly the same amount of treats in it. Carlos has 25 granola bars and 35 small popcorn balls. What is the greatest number of treat bags Carlos can make?

Answers

Answer:

5 bags

Step-by-step explanation:

Given

[tex]Granola\ Bars = 25[/tex]

[tex]Popcorn\ Balls = 35[/tex]

Required

Determine the greatest number of bags

This question illustrates greatest common factor (GCF).

The number of bags will be solved by getting the GCF of 25 and 35.

This is shown below:

[tex]25 = 1 * 5 * 5[/tex]

[tex]35 = 1 * 5 * 7[/tex]

[tex]GCF = 1 * 5[/tex]

[tex]GCF = 5[/tex]

Hence, Carlos will need 5 bags

The price of a DVD is $24.00 plus 8% sales tax.What is the sales tax on this DVD in dollars and cents?

B) 0.8
C) 1.92
D) 30

Answers

Answer:

Your answer is C) 1.92

Hope this helps ^_^

Answer:

Sales tax is $1.92 or 192 cents.

Step-by-step explanation:

Given the price of a DVD is $24.00 plus 8% sales tax.

we have to find the sales tax on this DVD in dollars and cents.

The sales tax is 8% can be calculated as

8/100 X $24

1.92

In cents

as one dollar equals 100 cents

∴ 1.92 dollar = $1.92 = 192 cents

Hence, sales tax is $1.92 or 192 cents.

So your answer is C!!

83x - 6) = 6(4x + 8)​

Answers

Answer:

[tex]x = \frac{54}{59}[/tex]

Step-by-step explanation:

I'm assuming you meant (83x - 6). Either way, the parentheses aren't needed there as there aren't any numbers outside of the parentheses on that side of the equation.

So:

Remember PEMDAS

P – Parentheses

E – Exponents

M – Multiplication /D – Division  (whichever comes first from left to right)

A – Addition /S – Subtraction (whichever comes first from left to right)

Nothing needs to be distributed on the left side, so let's distribute the right side.

6(4x + 8)

6 * 4x = 24x

6 * 8 = 48

Now we have 24x + 48

83x - 6 = 24x + 48

Now, we must isolate the x so that in the end, we can get x =

83x - 6 = 24x + 48

+ 6                    +6

83x = 24x + 54

-24x           -24x

59x = 54

Now, we have isolated the x! Finally, we want x to = 1 so that it will be x = instead of 59x =.

[tex]\frac{59x}{59} = \frac{54}{59}[/tex]

Because 54/59 does not divide into a rational number or simplify any further, we can keep it as a fraction.

[tex]x = \frac{54}{59}[/tex]
