Jacob went bowling over the weekend. On Saturday, he bowled at Bowlero, where he
rented shoes for $3.25 and paid $3.75 for each game. On Sunday, he bowled at the
Cowtown Bowling Center, where he rented shoes for $2.50 and paid $4.00 per game. If
he spent the same amount each day, how many games did he bowl? (Let the number of
games played = x.)

Answer:

Step-by-step explanation:

If you have 61 numbers, the middle number is the median. 30 numbers are below the median and 30 numbers are above the median. The middle number is the 61 number. At most and at least 30 numbers can be above the median. I think the statement is true.

Answer:

240

Step-by-step explanation:

Bottom rectangle volume:

4x8x5=160

The 2 top rectangles:

2x4x5=40

40x2=80

Total volume:

80+160=240

Answer:

Step-by-step explanation:

the side lengths are (400 - 4x)/2 = 200 - 2x

A = x(200 - 2x)

A = 200x - 2x²

Maximum area will occur when the derivative is set to zero.

dA/dx = 200 - 4x

0 = 200 - 4x

x = 200/4 = 50 ft

each field will be 50 x 33⅓ ft.

total area will be 5000 ft²

Which is not very big for a sports complex. I've owned houses with more floor space than that.

Answer:

10, 4, -1

Step-by-step explanation:

10×4=40

40×-1=-40

-40=-40

The three integers could be 8, -5, and 1.

A number without a decimal or fractional element is known as an integer, which can be both positive and negative, including zero.

Given that, the product of three integers is -40.

Since the product is negative, there should be at least one negative number.

The three numbers can be 8, -5, and 1.

8 × (-5) ×1 = -40

Hence, the three integers could be 8, -5, and 1.

Answer:

y=8x+3

Step-by-step explanation:

to check plug the numbers to the equation and you will that it is right

Answer:

f(x) = 8x + 3

Explanation:

I knew f(x) = mx +b is the formula for a linear equation and that when x = 0,

f(x) = b

So, when x = 0 in the table, f(x) = 3 and therefore b = 3

Now we can plug in f(x) = 11 and x =1 into f(x) = mx+b along with our b value

11 = m(1) + 3

solving for m we get m  =  8 which finishes our unknowns

f(x) = mx + b

f(x) = 8x + 3

Answer:

Step-by-step explanation:

(a) Solving the x-equation for u gives ...

  u = (x -1)/4

Differentiating both equations with respect to u, we have ...

  dy/du = 1 -4u

  dx/du = 4

Then dy/dx is ...

  dy/dx = (dy/du)/(dx/du) = (1 -4u)/4

Substituting for u gives ...

  dy/dx = (1 -4(x -1)/4)/4

  dy/dx = (2 -x)/4

__

(b) The approximate change in y is ...

  ∆y ≈ (dy/dx)(∆x)

For ∆x = 2.98 -3.00 = -0.02, and x=3, the approximate change is ...

  ∆y ≈ (2 -3)/4(-0.02)

  ∆y ≈ 0.005

Answer:

64

Step-by-step explanation:

Let the missing side be " x "

30 /  ( 30 + 10 ) = 48 / x.

30 / 40 = 48 / x

3 / 4 = 48 / x

3 * x = 4 * 48

x = 4 * 48 / 3

  = 4 * 16

x = 64

Answer:

Two shirts can be made

Step-by-step explanation:

We do have 3/4c of orange dye.

We do require 3/8c per T-shirt.

But, using math, it can be shown that 3/4c=2×3/8c

Looking at it this way: 3/4c = 2x3/8c

Where the 2 is the number of T-shirts we can produce.

It is easy now to see: 3/4c = 2x3/8c = 6/8c

So: 34c=68c=34c→ and all of this is orange dye
