Answer:

i)32C16

ii)1185408

<em><u>Explanation</u></em><em><u>:</u></em>

i)Total number of selected/eligible is 7+9+8+8=32

Total ways of selecting dance committee of 16 is

<em><u>3</u></em><em><u>2</u></em><em><u>C</u></em><em><u>1</u></em><em><u>6</u></em>

ii)Total ways of selecting 3 seniors from 8 is 8C3

and Total ways of selecting 6 juniors from 8 is 8C6

ways of selecting 2 sopho from 9 is 9C2

ways of selecting 5 freshman from 7 is 7C5

now, total way of selection come to be

8C3×8C6×9C2×7C5

=56×28×36×21

=1185408

A hot air balloon in flight begins to ascend at a steady rate of 120 feet per minute. After 1.5 minutes, the balloon is at an al
azamat

Answer:

The balloon will not reach 2,500 feet after 4 minutes.

Step-by-step explanation:

The equation of the line in the point-slope form is

y-y_1=m(x-x_1)

A hot air balloon in flight begins to ascend at a steady rate of 120 feet per minute, then the slope is

m=120

After x_1=1.5 minutes, the balloon is at an altitude of y_1=2,150 feet. This means, the line passes through the point (1.5, 2,150).

Substitute the slope and point coordinates into the equation:

y-2,150=120(x-1.5)

We know that after 3 minutes, the balloon is at an altitude of 2,330 feet. Check this:

2,330-2,150=180\\ \\120(3-1.5)=120\cdot 1.5=180\\ \\2,330-2,150=120(3-1.5)

Now, find the height after 4 minutes:

y-2,150=120(4-1.5)\\ \\y=120\cdot 2.5+2,150=300+2,150=2,450

Thus, the balloon will reach only 2,450 feet after 4 minutes.

worty [1.4K]

Answer:

\large\boxed{4.44=444\%,\ \dfrac{3}{5}=60\%}

Step-by-step explanation:

p\%=\dfrac{p}{100}\to p=p\cdot100\%\\\\\text{multiply a number by}\ 100\%\\\\4.44=4.44\cdot100\%=444\%\\\\\dfrac{3}{5}=\dfrac{3}{5}\cdot100\%=\dfrac{300}{5}\%=60\%

A mars rover traveled from point a to point b at a speed of 4 cm/sec. Worsening conditions during the return trip caused the rov
miskamm [114]

Using a system of linear equations, the distance between points A and B is 6000 cm

  • Initial speed = 4cm/sec

Time taken = Distance / speed

Let ; distance = d

<u>To</u><u> </u><u>time</u><u> </u><u>:</u><u> </u>

  • <u>t</u> = d / 4
  • <em>4t = d ______(1)</em>

<u>Fro</u><u> </u><u>time</u><u> </u><u>:</u><u> </u>

(t + 15 × 60) = d / 2.5

2.5(t + 900) = d

<em>2.5t + </em><em>2250</em><em> = d ______(2)</em>

Equate (1) and (2)

4t = 2.5t + 2250

4t - 2.5t = 2250

1.5t = 2250

t = 1500 seconds

From (1) :

d = 4t

d = 4(1500)

d = 6000 cm

Therefore, the distance from point A to B is 6000 cm
