Answer:

Marcia is 47 inches tall.

Step-by-step explanation:

Let's solve this step by step and try to visualize the situation.

• Carl: 73 inches tall

The second part of the question states that Carl's heigh is twenty-one inches less than two times Marcia's height. Add 73 + 21 to equal 94. Since Carl is 21 inches less that means that Maria is 21 inches more ( so that's why I added instead of subtracting) because we are trying to find Maria's equation.

Let x be Marcia's height

2x = 94

• The question staes that 73 is 21 inches less than two times Marcia's height which means that the equation 2x = 94 applies because 73 + 21 = 94

After simplifying the equation, we can get the answer that Marcia is 47 inches tall.

Answer:

Step-by-step explanation:

Givens

Carl = 73

Marcia = 2x - 21 = 73

Solution

2x - 21 = 73 Add 21 to both sides.

2x = 73 + 21 Combine

2x = 94 Divide by 2

2x/2 = 94/2

x = 47

Box A has a volume of 64 cubic meters. Box B is similar to box A. To create Box B, Box A's dimensions were divided by 2. What is

qwelly [4]

Answer:

8 m3

Step-by-step explanation:

Since Box A has a volume of 64 cubic meters, that means each side length is 4 m3. It says to make Box B, they divided these lengths by 2. With that info, you get 8 as your volume

Ksenya-84 [330]

Answer:

92.4% or 73/79

Step-by-step explanation:

You have to add up all the individual songs, which is 158. Then add up the number of songs that aren't classical, which is 146. Then divide 146 by 158 which gives you your answer.

Assume that all six outcomes of a six-sided number cube have the same probability. What is the theoretical probability of each r

Margarita [4]

Hey there! I am on the same one. :) I will help you out a little.

Assume that all six outcomes of a six-sided number cube have the same probability. What is the theoretical probability of each roll?
• 1: 1/6
• 2: 2/6
• 3: 3/6
• 4: 4/6
• 5: 5/6
• 6: 6/6

Using the uniform probability model you developed, what is the probability of rolling an even number?
1/6 Roll a number cube 25 times. Record your results here.

 1st toss=6 2nd toss=4 3rd toss=6 4th toss=6 5th toss=3 6th toss=3 7th toss=4 8th toss=2 9th toss=6 10th toss=5 11th toss=1 12th toss=4 13th toss = 5 14th toss =1 15th toss=4 16th toss=2 17th toss=2 18th toss=2 19th toss=6 20th toss=5 21st toss=3 22nd toss=4 23rd toss=3 24th toss=3 25 toss=5
How many results of 1 did you have? __2____________ How many results of 2 did you have? ____4__________ How many results of 3 did you have? ____5__________ How many results of 4 did you have? ______5________ How many results of 5 did you have? ______4________ How many results of 6 did you have? ______5________
Based on your data, what is the experimental probability of each roll? 1. 2/25 or 0.08

2. 4/25 or 0.16

3. 5/25 or 0.24

4. 5/25 or 0.2

5.4/25 or 0.16

6. 5/25 or 0.2Using the probability model based on observed frequencies, what is the probability of rolling an even number? 3/6 = ½ or 0.5
Was your experimental probability different than your theoretical probability? Why or why not? It somewhat is! The denominator is 25 for the experimental probability, and 6 for the theoretical probability.
Have a lovely day! Cheerio. :)

Solve for g. 8g + 3 = –6g + 13g + 13

pav-90 [236]

Answer: g = 10

Step-by-step explanation: 8g + 3 = –6g + 13g + 13

8g + 3 = (–6g + 13g) + (13)

8g + 3 = 7g + 13

8g + 3 - 7g = 7g + 13 - 7g

g + 3 = 13

g + 3 - 3 = 13 - 3
