A rectangle with a length of 22 feet and an unkown width,W, has a perimeter of 74 feet. Set up and slove an equation to find the vaulur of W

Answers

Answer: W=15

Step-by-step explanation: The equation you set up is 2(L) + 2(W)=74

2(22) + 2W=74

44+2W=74

What is the root when talking about a quadratic equation

Answers

The root is the x intercepts or the zeros of the problem

If I were to graph

(x-5)(x+4)=0

We need a number for x which makes this equation 0

The numbers are 5 or -4

These are the x intercepts of the parabola or roots

Answer:

The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

Answers

Answer:

There is 2.887 quarts of oil in the funnel

Step-by-step explanation:

Complete question

A funnel is in the shape of a cone with a radius of 4 inches and a height of

10 inches. The funnel is filled with oil. How many quarts of oil are in the funnel?

Solution

As we know, volume of the cone is given by

[tex]V = \frac{1}{3} \pi r^2 h[/tex]

Here,

V = volume of the cone

r is the radius of the base of the cone

h is the height of the cone

Substituting the given values in above equation, we get -

[tex]V = \frac{1}{3} *3.14*4*4*10\\V = 167.467[/tex] Cubic inch

As given

1 quarts = 58 cubic inch

Total number of quarts of oil

[tex]\frac{167.467}{58} \\2.887[/tex]

There is 2.887 quarts of oil in the funnel

A video game originally costs $63, but if you buy it before the end of May there is a 25% off sale. The sales tax is 9.5%. What is the final price of the video game if you buy it before the end of May?

Answers

Answer: $53.24

Step-by-step explanation:

Find the sales tax:

9.5*63.00=598.5

Then divide 598.5 by 100: 598.5/100= 5.985

Round: $5.99 ( sale tax amount )

Now we find the discount: 25*63.00= 1,575

Then divide it by 100 : 1,575/100= $15.75 ( discount amount )

Take the original price of the game and subtract it by the discount amount, then add the sales tax amount: 63.00-15.75= 47.25+5.99= $53.24

Answer: $53.24

Choose an equivalent system of equations to the following system:

Fx + Gy = H
Qx + Ry = S

6Fx + Gy = 6H
Qx + 6Ry = S
6Fx + 6Gy = 6H
Qx + Ry = S
Fx + 6Gy = 6H
Qx + Ry = S
6Fx + 6Gy = 6H
Qx − Ry = S

Answers

Answer:

B.  6Fx + 6Gy = 6H

   Qx + Ry = S

Step-by-step explanation:

Equivalent equations can be created many ways. One of the simplest is to multiply both sides of the equation by the same number. In the answer above, the first equation has been multiplied by 6. Nothing has been done to the second equation.

_____

Comments on other choices

A: some terms have been multiplied by 6. This changes the equation(s) so they are no longer equivalent to the ones you started with.

B: the correct choice

C: see A.

D: the first equation has been multiplied by 6, so that is equivalent to the original. The second equation has the sign of one of the terms changed, so it is now a different equation.

Answer:

6Fx + 6Gy = 6H

  Qx + Ry = S

Answers

Answer:

12

0.6/0.05

(0.6 x 100) / (0.05 x 100)

= 60/5 = 12

Step-by-step explanation:

number of pieces = total weight of the cheese / weight of each piece

0.6 / 0.05

to divide easily, convert the decimals to whole number by multiply both the denominator and numerator by 100

(0.6 x 100) / (0.05 x 100)

Devon’s tennis coach says that 72% of Devon’s serves are good serves. Devon thinks he has a higher proportion of good serves. To test this, 50 of his serves are randomly selected and 42 of them are good. To determine if these data provide convincing evidence that the proportion of Devon’s serves that are good is greater than 72%, 100 trials of a simulation are conducted. Devon’s hypotheses are: H0: p = 72% and Ha: p > 72%, where p = the true proportion of Devon’s serves that are good. Based on the results of the simulation, the estimated P-value is 0.06.

Find the perimeter of a rectangle with length (x-5) and width (3x+1).

Answers

Answer:

8x-8

Step-by-step explanation:

P=s+s+s+s or in this case P= 2l+2w

P= 2(x-5)+2(3x+1)

P=(2x-10)+(6x+2)

P=8x-8

8x-8 will be the perimeter of a rectangle with length (x-5) and width (3x+1).

What is a rectangle?

A rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Perimeter of rectangle = 2( length + width).

Given that,

Length of rectangle = x - 5

Width of rectangle = 3x + 1

Now,

Perimeter of rectangle = 2(width + length)

Perimeter of rectangle = 2(3x + 1 + x - 5)

The perimeter of the rectangle = 8x - 8

Hence "8x-8 will be the perimeter of a rectangle with length (x-5) and width (3x+1)".
