Liz's age is two-thirds of Debbie's age. Debbie's age is half of Freya's age. what is the ratio of Liz's age to Freya's age?
Answers
Answer:
Let's start by using variables to represent the ages of the three people:
Let L be Liz's age.
Let D be Debbie's age.
Let F be Freya's age.
From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:
L = (2/3)D
We also know that Debbie's age is half of Freya's age, so we can write:
D = (1/2)F
To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:
F = 2D
Now we can substitute this expression for F into the equation for Liz's age:
L = (2/3)D = (2/3)(1/2)F = (1/3)F
So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.
What is the distance around the circular edge of the clock face?

Answer:
e
Step-by-step explanation:
The distance around the circular edge can also be referred to as the perimeter or the circumference.
The formula for circumference is:
C = \(\pi\)d
C = (3.14)(12)
C = 37.68
The distance around the circular edge of the clock face is 37.68 feet.

a baby gorilla had a mass of 2620 grams at birth, 2960 after 10 days, and 3300 grams after 20 days. What is the average number of grams that the baby gorilla grew each day during the first 10 days and during the next 10 days?
show work
Answers
The baby gorilla grew 340 grams in the first 10 days. This is an average of 34 grams per day. The baby gorilla grew 340 grams in the next 10 days. This is an average of 34 grams per day. The baby gorilla grew at the same rate in the first 10 days and the next 10 days.
Here is the solution:
340 grams / 10 days = 34 grams per day
340 grams / 10 days = 34 grams per day
34 grams per day = 34 grams per day
Therefore, the average number of grams that the baby gorilla grew each day during the first 10 days and during the next 10 days is 34 grams per day.
What is the surface area of the figure? PLEASE HELP ASAP !! 7th grade Geometry
Answers
Answer:
SA = 578ft²
Step-by-step explanation:
First, we have to know the formula of finding the surface area of a rectangular prism.
Formula: 2(wl + hl + hw)
w = width l = length h = height
Next, we separate the composite figure into two rectangular prisms.
Since we have all measurements, let's use that to find the SA.
The first shape (to the left)
SA = 2(wl + hl + hw)
SA = 2(4 x 9 + 9 x 9 + 9 x 4)
SA = 2(36 + 81 + 36)
SA = 2(153)
SA = 306
Then, we do the other shape(to the right)
We know the measurement of length = 4 because it is the same measurement as the width
SA = 2(wl + hl + hw)
SA = 2(4 x 4 + 15 x 4 + 15 x 4)
SA = 2(16 + 60 + 60)
SA = 2(136)
SA = 272
Lastly, we add those two
306 + 272 = 578
Therefore, SA = 578ft²

D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

how to check : 3x+5=11
Answers
Answer:
There are two ways to check if 3x+5=11 is true:
Subtract 5 from both sides of the equation. This will isolate x on the left-hand side of the equation.
3x = 6
Divide both sides of the equation by 3. This will divide both sides of the equation by 3, which will cancel out the 3 on the left-hand side of the equation, leaving x by itself.
x = 2
You can also check if 3x+5=11 is true by plugging in 2 for x. If you do this, you will get 3(2)+5 = 6+5 = 11. Therefore, 3x+5=11 is true when x=2.

A home furnishing store sells 6 chairs for $900. Martin buys 2 such chairs for her new home. How much did she spend on the purchase?
Answers
$300 if it is $900 for 6 chairs
if it is $900 each(expensive chairs), it would be $1800
Answer:
$300
Step-by-step explanation:
It would be $300 dollars for 2 chairs because $900 dollars divided by 6 = 150 so each chair is $150. Since we are buying 2 chairs it would be 150 time 2 which equals 300. So she spent $300 on her purchase.

? 40.50
? 42
Answers
Answer:
C) $40.50
Step-by-step explanation:
It is given to you that 20 articles cost $90. Find the unit cost of the articles. Divide the total cost of the articles with the amount of articles there are:
$90/(20 articles) = $4.50/article.
Each article costs $4.50 each.
Next, find the cost of 9 articles. Multiply the total amount of articles with the unit cost:
4.50 x 9 = 40.50
C) $40.50 is your answer.

How to calculate the circumference of a circle?To calculate the circumference of a circle we must apply the following formula:

2\(\pi\)1 = 6.282\(\pi\)2 = 12.59So, to find the difference of the circumferences of both circles we must subtract the smaller number (circumference of the small circle) from the larger number (circumference of the large circle).
12.59 - 6.28 = 6.31According to the above, the difference of the circumferences would be 6.31 cm.
How to calculate the area of the circle?To calculate the area of the circle we must apply the following formula.

How did you decide where to place your line of best fit? Describe your reasoning.
Based on your data, describe the relationship between age and the number of U.S. states a person can name in 60 seconds.
Do you see any areas in your data or points that could be considered clusters or outliers? Explain your answer in complete sentences.
Trolls will be reported
Answers
Answer:So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.
So basically the units are counting up by 5.
The x axis is age in years and y axis is the number of US states named in 60 seconds.
Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.
(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)
