at t = 5:

x(5) = 100
y(5) = 200 - 25
       = 175

\frac{y(5)}{x(5)} = \frac{175}{100} = 7/4

Answer:

See below.

Step-by-step explanation:

The corners of the square are:

(-7, 6) which becomes (-6, 7)

(-2, 6) which becomes (-6, 2)

(-7, 1) which becomes (-1, 7)

(-2, 1) which becomes (-1, 2)

From the top left corner of the square, ABCD rotates to ACDB (clockwise), so Darla is correct.

The new square is in the same quadrant as the original, so quadrant 2.

Jeremy is packaging a stew containers.There are 8 3/4 cups of stew that need to put into 5 to go containers equally.How many cup
11111nata11111 [884]

Answer:

1 3/4 cups

Step-by-step explanation:

In order to be able to equally divide the stew into 5 containers we need to turn everything into the same format, in this case it would be by multiplying the whole number and the denominator and then adding the numerator like so

(8 * 4) + 3 =  \frac{35}{4}

Now we can divide the numerator by 5 (container) in order to calculate how much stew each container will get.

\frac{35}{4} / 5 = \frac{7}{4}

So each container will get 7/4 of the Stew or 1 3/4 cups

Tju [1.3M]

Answer:

Each project has 2.500 man-hours

Step-by-step explanation:

Available man hours: 5000

For two projects          Costs $

X: project A                     10

Y: project B                     12

Approach:

X + Y = 5000 => X = 5000 - Y

10 * X + 12 * Y = 55000

replacing:

10 * (5000 - Y) + 12 * Y = 55000

50000 - 10 * Y + 12 * Y = 55000

2 * Y = 55000 - 50000

Y = 5000/2

Y = 2500

For X:

X = 5000 - 2500

X = 2500

The number of hours available for each project are:

Projects Man            hours

X: project A              2500

Y: project B              2500
