Anna11 [10]

Answer:

$2.50 per movie and $6.50 per video game.

Step-by-step explanation:

The correct answer is $6.50 for each video game and $2.50 for each movie. My work:

3 x 2.50 = $7.50 and 5 x 6.50 = $32.50

32.50 + 7.50 = $40.00

12 x 2.50 = $30.00 and 2 x 6.50 = $13.00

30.00 + 13.00 = $43.00

Hope i helped you

Please help! What is the line's slope??
MariettaO [177]
The slope is the rise over run. Basically, any line has a constant increase. If you are looking at a line on a graph and each point it meets at is 1 up and 1 over, the slope is 1. Say the line goes up two and over one for each time it meets an actual point, the slope would be 2. If it is 1 up and 2 over, it would be 1/2.

A piece of wire 28 ft long is cut into two pieces. One piece is used to form a square, and the remaining piece is used to form a
marusya05 [52]

Answer:

Wire should be cut in two parts with the length = 15.69 ft and 12.31 ft

Step-by-step explanation:

Length of the wire = 28 ft has been cut in two pieces.

One piece is used to form a square and remaining piece to form a circle.

Let the length of the wire which forms the square is 'l' ft.

Area of the square = (side)²

Perimeter of the square = 4(side) = l

Length of one side = \frac{l}{4}

So, the area of the square = \frac{l^{2}}{16} ft²

Now length of the remaining part = perimeter of the circle = (28 - l) ft

2πr = (28 - l)

r = \frac{28-l}{2\pi }

Area of the circle formed = πr²

= \frac{\pi(28-l)^{2} }{4(\pi )^{2} }

= \frac{(28-l)^{2}}{4\pi }

Combined area of the square and circle

= \frac{l^{2}}{16} + \frac{(28-l)^{2}}{4\pi }

= \frac{l^{2}}{16} + \frac{(28-l)^{2}}{4\pi }

Now to maximize the area we will find the derivative of the area with respect to l.

\frac{dA}{dl}=\frac{d}{dl}[\frac{l^{2}}{16}+\frac{(28-l)^{2}}{4\pi}]

= \frac{d}{dl}[\frac{l^{2}}{16}+\frac{(28)^{2}+l^{2}-56l }{4\pi }]

= \frac{2l}{16}+\frac{(2l-56)}{4\pi }

Now equate the derivative to zero.

\frac{2l}{16}+\frac{(2l-56)}{4\pi } = 0

(2l-56)=-\frac{2l}{16}\times 4\pi

(2l-56)=-\frac{\pi l}{2}

2l+\frac{\pi l}{2}=56

\frac{(4l+l\pi )}{2}=56

l(4 + π) = 112

l(4 + 3.14) = 112

l = \frac{112}{7.14}

l = 15.69 ft

Length of the other part = 28 - 15.69 = 12.31 ft

Therefore, wire should be cut in two parts with the length = 15.69 ft and 12.31 ft

Multiply to give you 10 and add to give you 7.
Harrizon [31]

<u>Answer:</u>

<h2>2 and 5</h2>

<u>Steps:</u>

a. xy = 10

b. x+y = 7

x+y = 7

y = 7 - x

xy = 10

x(7 - x) = 10 (substitution of y)

7x - x² = 10

-x² + 7x - 10 = 0

here we have a quadratic equation that we will solve by using the quadratic formula

a = -1 | b = 7 | c = -10

x = (-7±√((-7)²-4×(-1)×(-10)))/2×(-1)

x = (-7±√(49-40))/-2

x = (-7±√9)/-2

x = (-7±3)/-2

x = -4/-2 , -10/-2

x = 2 , 5

<u>check:</u>

2×5 = 10

2+5 = 7

- 3/8 + 2/7 - ( - 5/11) + blank + 3/8 = 5/11
irinina [24]

Step-by-step explanation:

-3/8+2/7+5/11+x+3/8=5/11

cancel the -3/8 and 3/8 and the 5/11 on the right and left hand side because they cancel out

which leaves x = -2/7
