Lucas is selling ribbons to raise money for the Juvenile Diabetes Research Foundation. His expenses include $46 for materials, plus $0.02 per ribbon. If Lucas charges $0.25 per ribbon, how many ribbons does he need to sell to break even? Write a system of equations that represents the situation. Let x represent the number of ribbons, and let y represent the expense or revenue. Solve the system of equations.

Answer:

Step-by-step explanation:

The graph of a quadratic function is a U-shaped curve called a parabola. One important feature of the graph is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value. In either case, the vertex is a turning point on the graph. The graph is also symmetric with a vertical line drawn through the vertex, called the axis of symmetry. These features are illustrated in (Figure).

Graph of a parabola showing where the x and y intercepts, vertex, and axis of symmetry are.  

The y-intercept is the point at which the parabola crosses the y-axis. The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function, the values of x

Answer:

-3x - 2

Step-by-step explanation:

-(x - 5) ⇒ -x + 5

-(2x + 7) ⇒ -2x - 7

-x + 5 - 2x - 7 ⇒ -3x - 2

multiply by sign:-x+5-2x-7

collect like term:-x-2x+5-7

simplify:-3x-2

Step-by-step explanation:

you can find the diagonal of a rectangle if you have the width and the height

Answer:

B) 9 square units

Step-by-step explanation:

Split the shape into a right triangle and a rectangle.

The rectangle is 2 by 3, so multiply 2 x 3 for the area: 6.

The triangle has a height of 3 and a base of 2. Multiply to get 6. Then divide by 2 to get: 3.

Add 6 + 3 to get 9 square units.

Hope it helps!

Answer:

Step-by-step explanation:

A graphing calculator provides a nice answer for these questions. It shows the maximum height is 48.6 feet, and the time in air is 3.4 seconds.

__

The equation can be rewritten to vertex form to find the maximum height.

  h(t) = -16(t^2 -54/16t) +3 . . . . . group t-terms

  h(t) = -16(t^2 -54/16t +(27/16)^2) + 3 + 27^2/16

  h(t) = -16(t -27/16)^2 +48 9/16

The maximum height is 48 9/16 feet, about 48.6 feet.

__

The air time is found at the value of t that makes h(t) = 0.

  0 = -16(t -27/16)^2 +48 9/16

  (-48 9/16)/(-16) = (t -27/16)^2 . . . . . . . subtract 48 9/16 and divide by -16

  (√777 +27)/16 = t ≈ 3.4297 . . . . . square root and add 27/16

The time in air is about 3.4 seconds.

Answer:

32 quarters and 3 dimes

Step-by-step explanation:

you could do 4 x 8 to get to the 8 dollars so 4 x 8 = 32 so that would be 32 quarters now you got 30 cents left that will be the dimes so 3 dimes

Answer:

You didn't post it up for me to see, I can try to help.

Answer:

3 divided by 4 will equal 0.75 which is equivalent to 0.75. or you can do 6/8 which will also equal 0.75. and 6/8 is equivalent to 3/4. so therefore it's confirmed that 3/4 is equivalent to 0.75

Answer:

8:27

Step-by-step explanation:

on ape x

The ratio of their volumes is 8:27.

We have given that,

If two cylinders are similar and the ratio between the altitude lengths is 2:3.

We have to determine the ratio of their volumes.

Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.

Therefore the ratio of their volume is 8:27

Step-by-step explanation:

Here important information is missing. That is total number of divide.

However, it is given that riley made groups of 12 with 1left over from total number of divide. So, total number of divides on the drawing must be a multiple of 12 +1. It can be any number like 12n+1, where n is an integer. Then we ca find total number of group.

$15 in interest

Step-by-step explanation:

sorry if it is wrong. I found 5% of 300 which is 15.

$15  money will tameka pay in interest.

Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.

Here, we have,

formula: I = Prt.

here, we get,

given that,

Tameka borrowed $300 to buy a digital music player she will pay the money back in 1 year at 5%simple interest.

P=$300

r=5%

t=1year

so, I =$300*5%*1

       =$15

Hence, $15  money will tameka pay in interest.
