Bobby and Marie are running a lemonade stand.They spend $12 on all their materials and charge $1.50 for each cup of lemonade. If they sell 20 cups of lemonade, how much money would they make(or lose)?

Answers

Answer:

$18

Step-by-step explanation:

First you would multiply $1.50 by how many cups of lemonade they sell (20). Your answer for this would be $30. After that you want to subtract the $12 from the $30, because they spent $12 on materials. Then you get $18, which is your answer. Hope this helps :)

$30 is how much they made in total, 30-12= $18 which is their profit.

What is the slope of the line?

Answers

Answer:

slope = 3

Step-by-step explanation:

if each square is equal to 1

The slope has to be 3.

you can see it, because between those 2 point you can count 3 spaces in y-vertex, and 1 space in x-vertex

what that means is that we will move 3 steps up (or down) for each 1 space in x-vertex.

Solve the quadratic equation by factoring.
4x² - 20x + 28 = 3

A) x = 5
B) x = 5/2
C) x = 2/5
D) x = - 5/2

Answers

Answer:

B)  x = 5/2

Step-by-step explanation:

subtract 3 from each side to get:

4x² - 20x + 25 = 0

this is the difference of 2 squares:

(2x -5)² = 0

one solution, x = 5/2

Answer:

B)  x = 5/2

Step-by-step explanation:

4x² - 20x + 28 = 3

Move terms to the left side

4x² - 20x + 28 - 3 = 0

Subtract the numbers

4x² - 20x + 25 = 0

Use the quadratic formula

[tex]x =\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex]

Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

4x² - 20x + 25 = 0

a = 4

b = -20

c = 25

x = [tex]\frac{-(-20)+\sqrt{(-20)^{2}-4x4x25 } }{2x4}[/tex]

Evaluate the exponent

x = [tex]\frac{20+\sqrt{400-4x4x25 } }{2x4}[/tex]

Multiply the numbers

x = [tex]\frac{20+\sqrt{400-400 } }{2x4}[/tex]

Subtract the numbers

x = [tex]\frac{20+\sqrt{0} }{2x4}[/tex]

Evaluate the square root

x = [tex]\frac{20+0 }{2x4}[/tex]

Add zero

x = 20 / 2 x 4

Multiply the numbers

x = 20 / 8

Cancel terms that are in both the numerator and denominator

x = 5/2

Answers

Answer:

541/2 square

Step-by-step explanation:

What is the volume of the box if it is scaled down by a factor of 1/10

we know that

the volume of the smaller box=[scale factor]³*volume original box

scale factor=1/10

volume original box=5,120 cm³

so

volume of the smaller box=[1/10]³*5,120-----> 5.12 cm³

Steve will roll a number cube, numbered 1-6, twice. What is the probability of rolling a number greater than 4, then
rolling an odd number?

Answers

Answer:

6/36 or 1/6

Step-by-step explanation:

To find the probability of rolling a number greater than 4, then rolling an odd number, you must multiply the probability of rolling numbers greater than 4 by the probability of rolling an odd number. In numbers 1-6, there are two number greater than 4: 5 and 6. The probability of an event is the specific factor over the total amount of results or objects. The probability of rolling a number higher than 4 is 2/6, or 1/3. In numbers 1-6, there are 3 odd numbers: 1, 3, and 5. The probability of rolling an odd number is 3/6, or 1/2. 3/6 times 2/6 is 6/36, and when simplified, it becomes 1/6.

graph 3x+6y=18 In the box below, enter the y value when x = 2.

Answers

Answer:

y = 2

Step-by-step explanation:

3x + 6y = 18

3(2) + 6y = 18

6 + 6y = 18

Since 18 - 6 = 12, y will equal 2.

6 + 6(2) = 18

6 + 12 = 18

The coordinates to graph the equation would be (2, 2).

Step-by-step explanation:

Find the number that multiplies to make -27 and adds to make 6. In this case it is 9 and -3. Use these numbers to factorise.

Answer:

(x-3) (+9)

Step-by-step explanation:

To know what numbers to use, factor out the constant (-27).

You would get the numbers : 1,3,9,27.

Then figure out which numbers would make the 6x true. In this case, we would need the 3 and 9. They also need to add up to 6x, so the 3 needs to be negative.

-3 & 9

Then form the factors:

Actually Welcome to the concept of Locus of a shape.

Here, the left movement is in x direction and vertical or up movement is in the y direction.

so we get as,

A(1,-2) ==> 1 towards left => 0

and 3 units up => 1

hence the new co-ordinates are A(0,1)

hence, A(0,1) is correct option
