Answer: Choice B

$(x,y) \to \left(\frac{5}{2}x,\frac{5}{2}y\right)$

=========================================================

Explanation:

When dilating with respect to the origin, any point of the form (x,y) moves to (kx, ky) for some real number k. The k is the scale factor.

Point C is at (-2,2). It moves to C ' (-5,5)

The jump from x = -2 to x = -5 is "times 5/2" since kx = (5/2)*(-2) = -5

The same scale factor is used when going from y = 2 to y = 5.

Both x and y coordinates are multiplied by 5/2 to move from (-2,2) to (-5,5)

Therefore, the dilation rule we use is $(x,y) \to \left(\frac{5}{2}x,\frac{5}{2}y\right)$

-----------

We could have these steps to confirm

$(x,y) \to \left(\frac{5}{2}x,\frac{5}{2}y\right)\\\\(-2,2) \to \left(\frac{5}{2}*(-2),\frac{5}{2}(2)\right)\\\\(-2,2) \to (-5,5)\\\\$

There are 7.48 gallons in a cubic foot. If residents of the apartment building are using the water from the tower at an average

Talja [164]

Answer:

Step-by-step explanation:

So, volume is always cubed since you have l x w x h.

A cubic ft is 12 in x 12 in x 12 in = 1728 in3. If we assumed that the aquarium has a volume of around 35328.78 in squared. Hence,

35328.78/1728 = 20.44

20.44 x 7.48 = 152.89

About 153 gallons

Noted that the water was used at the rate of 56 gallons per minute.

56 gallons -------- 1 minute

153 gallons --------- x minute (s)

56gallon × Xminutes = 153 gallons × 1 minute

X = 153/56

X = 2.7321 minutes

Hence, it will take 2.7321 minutes to drain the tower

Easy 6th grade math! Please help!

Pie

Answer:

Step-by-step explanation 10 + 2.50d = 850

David starts with $10 and each day he earns $2.50. The d represents a variable and can be any number.

To find d you must solve the equation.

10 + 2.50d = 850

2.50d = 840 (subtract 10 from 850)

d = 336 (divide 840 by 2.50)

It will take David 336 days to save $850.
