Answer:

In the beginning, there is 60 L of water in the bathtub. The water drains out from the bathtub at 2.5 L per minute. How many minutes does it take until all of the water is drained out?

Zero of the function: (24, 0)

The value 24 min represents the number of minutes it takes for the water to completely drain out from the bathtub.

Step-by-step explanation:

Zero of the function is when y=0

0 = 60 -2.5 x

x = 24

How to change 45% into a fraction How to change 120% into a fraction

Eddi Din [679]

Answer: 3/25 and 9/20

Step-by-step explanation:

We take the number and covert it into a fraction

A 2 digit Numerator = a 3 digit denominator

A 3 digit Numerator = a 4 digit denominator

And so on...

Then We can reduce,

45/100 = 9/20

120/1000 = 3/25

Hope this helped!

A circle has a radius of length r. If you mark off an arc on the circle of length 2r what is the measurement of the angle that s

Inessa05 [86]

A full circle has a circumference of 2πr and an angle of 2π radians.

Set up a proportion:
2πr - 2π rad
2r - x rad

$2\pi r \times x = 2\pi \times 2 r \\
2\pi r x=4 \pi r \\
x=\frac{4 \pi r}{2 \pi r} \\
x=2$

The answer is D. 2 radians.

Help me please assap

Reil [10]

Answer: G

Step-by-step explanation:

(x, y) → ( $\frac{1}{8}x$ , $\frac{1}{8}y$ )

means that the new quadrilateral will be $\frac{1}{8}$ the size of the original quadrilateral, so it will be smaller because the it maps to a fraction that is less than 1.

Answer:

General Equation of a Line

$General Equation \\(y - y_{1} )= m (x-x_{1}) \\Slope=m= \frac{x_{2}-x_{1} }{y_{2}-y_{1} } \\\\Given:\\p_{1}=(7,-4)\\p_{2}=(-1,2)\\Solution:\\m=(\frac{-1-7}{2-(-4)}) =\frac{-8}{6}\\y-(-4) = (\frac{-8}{6} )(x-7)\\y+4=\frac{-8x}{6} + 56\\y=\frac{-8x}{6} + 52 \\\\The\\ equation \\ is \\ y=\frac{-8x}{6} + 52$

Step-by-step explanation:

Find the slope first and then place the values on the general formula. The final step is to solve for y
