Answer:

40 girls

Step-by-step explanation:

Set up a proportion where x is the number of girls in band class:

\frac{3}{5} = \frac{24}{x}

Cross multiply and solve for x:

3x = 120

x = 40

So, there were 40 girls in band class.

Answer: There are 40 girls in band class.

____________________________________________________________

The ratio for this problem is:

\frac{3}{5} = \frac{24}{x}

To get from 3 to 24, you would multiply by 8. You need to do the same thing to 5 to get x.

5 times 8 equals 40.

There are 40 girls in band class.

Write an exponential function for the value, y, after x years
Anon25 [30]

Step-by-step explanation:

<u>Step 1:  Set x equal to 0 to find the y-int</u>

y = 10000(1 - 0.40) → Not an exponential equation

y=10000(1-0.40)^0 → 10,000 → Works for first test

y = 10000(1-0.60)^0 → 10,000 → Works for first test

y = 10000(1+0.40)^0 → 10,000 → Works for first test

<u>Step 2:  Set x equal to 1</u>

y=10000(1-0.40)^1 → 6,000 → Works for second test

y = 10000(1-0.60)^1 → 4,000 → Does not work for the second test

y = 10000(1+0.40)^1 → 14,000 → Does not work for the second test

Answer:  The answer is Option B

What is the value of x if the quadrilateral is a rhombus? please help
stiks02 [169]
In a rhombus, all sides are equal:

5x = 15
and x = 15/5 = 3

(you could have done the same thing with the other side: 5x = 4x +3)

A car starts on a trip and travels at an average speed of 50 miles per hour. Two hours later, a second car starts on the same tr
umka21 [38]

The distance traveled by first car is 50t + 100.

The distance traveled by second car is 70t.

The distance between the two cars after time, t is d = 100 - 20t.

The ratio of the distance traveled by the cars is (70t) / (50t + 100).

<h3>Distance traveled by each vehicle is calculated as follows;</h3>

The distance traveled by each vehicle at the given time is calculated as follows;

<h3>Distance traveled by first car</h3>

D₁ = speed x time

D₁ = 50(t + 2)

D₁ = 50t + 100

<h3>Distance traveled by the second car</h3>

D₂ = 70t

<h3>Distance between the two cars after time, t</h3>

d = D₁ - D₂

d = (50t + 100) - 70t

d = 100 - 20t

<h3>Ratio of the distance traveled by the cars</h3>

D₂/D₁ = (70t) / (50t + 100)

If a cat falls out of a tree, it has a probability of 0.92 that it will land
Alex_Xolod [135]

The probability that the cat lands on its feet both times it falls out of a tree is 0.85

<h3>How to determine the probability?</h3>

The probability that the cat lands on its feet is given as:

P(Feet) = 0.92

The probability that it lands on its feet twice is calculated using:

P = P(Feet) * P(Feet)

So, we have:

P = 0.92 * 0.92

Evaluate

P = 0.85

Hence, the probability is 0.85

Craig likes to collect video records last year he had 10 records his collection now has 12 records what is the percent increase
algol [13]
I believe the answer is a 20% increase because 12-10 equals 2. there is a 2 record difference so 2 out of 10 is 1/5 of the whole, but you have to convert the numbers and 1/5 of the whole of 100 is 20. sorry if that didn’t make much sense
