There is a bag with only milk and dark chocolates. The probability of randomly choosing a dark chocolate is 3 8 . There are 21 d

aliina [53]

Answer:

Number of milk chocolate in beg = 56

Step-by-step explanation:

Given:

Probability of randomly choosing a dark chocolate = 3/8

Number of dark chocolate = 21

Find:

Number of milk chocolate in beg

Computation:

Number of milk chocolate in beg = Number of dark chocolate / Probability of randomly choosing a dark chocolate

Number of milk chocolate in beg = 21 / [3/8]

Number of milk chocolate in beg = 21[8/3]

Number of milk chocolate in beg = 7[8]

Number of milk chocolate in beg = 56

Horizontal asymptote

vodomira [7]

Answer:

H.A.=4

Step-by-step explanation:

If the bottom equation is factored, you get (x+1)(x-4)

If the V.A. is -1 ( gotten by putting [x+1] equal to zero I'm guessing) then the H.A. can be gotten by putting (x-4) equal to zero.

Also, I graphed it.

Mr.Mitchell was doing an experiment about gratity he dropped a basketball off the roof of a building 53.9 feet tall . It took hi

IRINA_888 [86]

The basketball fell at rate of 9.8 feet per second

Step-by-step explanation:

The rate is the distance per unit time

Here

Given

Distance = height = h = 53.9 feet

time = t = 5.5 sec

The rate will be given as:

$Rate = \frac{Height}{time} = \frac{h}{t}\\= \frac{53.9}{5.5}\\= 1.78\\$

Hence,

The basketball fell at rate of 9.8 feet per second

Which system of equations is graphed on the coordinates below

Crazy boy [7]

Answer:

C

Step-by-step explanation:

Blue line:

$(-4, 0), (0, -2) \\m = \frac{\triangle y}{\triangle x} = \frac{0 - (- 2)}{-4 - 0} = \frac{2}{-4} = -\frac{1}{2}\\\text{y-intercept (c) is when x = 0}\\x = 0 \rightarrow y = -2\\y = mx + c\\y = -\frac{1}{2}x - 2\\2y = -x - 4\\x + 2y = -4$

Red line:

$(5, 0), (0, -5) \\m = \frac{\triangle y}{\triangle x} = \frac{0 - (- 5)}{5 - 0} = \frac{5}{5} = 1\\\text{y-intercept (c) is when x = 0}\\x = 0 \rightarrow y = -5\\y = mx + c\\y = 1x - 5\\y - x = -5\\-y + x = 5\\x - y = 5$
