Answer:

Step-by-step explanation:

3/x = sin45

x = 3/sin45

x = 3 / ½(√2)

x = 3(2/√2)

x = 3((2√2)/2)

x = 3√2

Ellie practices piano 2/3 h per day, several days each week. She practiced piano 32/23 hours during the summer.
butalik [34]

Let us assume that the number of days she practiced the piano to be "d"

Since she practiced 2/3 hours a day, the total number of hours would be: 2/3*d

Now we are given the total number of hours during summer that she practiced  be be equal to 32/23

So we equate 2/3 * d to 32/23 to find d

2/3*d = 32/23

d = (32/23)/ (2/3)

d = (32/23) * (3/2)

d = 48/23 hours

The equation that can be used to find the number of days that she practiced piano during the summer is 2/3*d = 32/23

mars1129 [50]

Answer:

The absolute change in the height of the water is 9.5 inches

Step-by-step explanation:

Given

l =24in --- length

w = 15in --- width

h =12in --- height

V_1 = 900in^3 --- the volume removed

Required

The absolute change in the height of the water

First, calculate the base area (b):

b = l * w

b =24in * 15in

b =360in^2

The height of the water that was removed is:

<em />H = \frac{V_1}{b}<em> i.e. the volume of the water removed divided by the base area</em>

H = \frac{900in^3}{360in^2}

H = \frac{900in}{360}

H = 2.5in

The absolute change in height is:

\triangle H = |h - H|

\triangle H = |12in - 2.5in|

\triangle H = |9.5in|

\triangle H = 9.5in
