Question 17 Unsaved

Mathematics
2 answers:

The probability of drawing a blue ball from the first urn is 6/(4 + 6) = 6/10 = 3/5.

The probability of drawing a blue ball from the second urn is 2/(2 + 6) = 2/8 = 1/4.

Since we want to find the probability that both balls from each urn are blue, we multiply our answers: 3/5 * 1/4 = 3/20.

The answer is the fraction 3/20.

An airplane at 30,100 feet above the ground begins descending at the rate of 2150 feet per minute. Write and solve a linear equa
IrinaVladis [17]

Answer:

30100-2150x and it would take 14 minutes to reach the ground.

Step-by-step explanation:

30100 feet is out starting y coordinate, and since 2150 is always changing depending on the amount of time we multiple it by x (the amount of minutes) therefor we can create the equation 30100-2150x and when we plus in 14 the equation would equal 0

What is the value of t?
solmaris [256]

Answer:

A) t = -3

Step-by-step explanation:

We have the expression \frac{(t-12)}{2}=\frac{3t}{2}-3 and we have to find the value of t.

First we are going to reorder the expression:

\frac{(t-12)}{2}=\frac{3t}{2}-3\\\\3=\frac{3t}{2}-\frac{(t-12)}{2}\\\\3=\frac{3t-t-(-12)}{2}\\\\3=\frac{2t+12}{2}

Now we have to multiply each side by 2,

3=\frac{2t+12}{2}\\\\3.2=\frac{2t+12}{2}.2\\\\6=2t+12

Subtract (-12) in both sides,

6=2t+12\\6-12=2t+12-12\\-6=2t

Divide both sides in 2,

-6=2t\\\frac{-6}{2} =\frac{2t}{2} \\-3=t

The answer is option A) t = -3.
