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?
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.

11. A scuba diver's elevation changed by -123 feet every minute. This was
1½ times the rate of change for a second scuba diver. What was the rate of
change in elevation of the second scuba diver in feet per minute?
Answer:
The rate of change in elevation for the second scuba diver is -82 feet per minute.
Step-by-step explanation:
-123 feet every minute.
1.5x more than 2nd diver.
-123/1.5 = 2nd diver rate
2nd diver rate = -82
The rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.
Given that, a scuba diver's elevation changed by -123 feet every minute.
What is constant rate of change?When something has a constant rate of change, one quantity changes in relation to the other. For example, for every half hour the pigeon flies, he can cover a distance of 25 miles. We can write this constant rate as a ratio. For ratios, it's always a good idea to state both units in whole terms.
1½=1.5 times the rate of change for a second scuba diver
Now, rate of change in elevation of the second scuba diver
= -123/1.5
= -82 feet per second
Hence, the rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.

Margo is wrapping a box that is 7 inches long, 10 inches wide, and 4 inches high. How much wrapping paper will she need to cover the entire box?
Answer:280 in
Step-by-step explanation: First we multiply the length by the width and that would be 7 by 10 and we would get 70. Next we multiply the height by the total of (l x w), so 4 x 70 would be 280. Margo needs a total of 280 inches of wrapping paper to cover the entire box. Hope this helps! :)

Shade all products in this multiplication table that appear most frequently. List the multiplication problems that create them. Why do they appear so much?
And also
List all the numbers between 1 and 50 that do not appear in this multiplication table. Why are they missing?
Answer:
Step-by-step explanation:
a. Shade all products in this multiplication table that appear most frequently - 6, 8, 12, 18, and 24. All numbers appear 4 times on the table.
b. 6=3x2=2x3=1x6=6x1
12=4x3=3x4=2x6=6x2
18=9x2=2x9=3x6=6x3
24=4x6=6x4=3x8=8x3
c. The numbers which appear 4 times have two distinct factorizations into single digit numbers (up to the order of the factors): for example, 24=4x6=3×8.
d. The numbers that do not appear in the multiplication table are 11, 13, 17, 19, 23, 29, 31, 37, 39, 41, 43, 47
e. The reason is that they are all prime numbers that are more than 9.
Which equation illustrates the distributive property of multiplication over addition?
A. 6(3a + 4b) = 18a + 4b
B. 6(3a + 4b) = 18a + 24b
C. 6(3a + 4b) = (3a + 4b)6
D. 6(3a + 4b) = 6(4b + 3a)

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500

Thx.
Answer:
Look at the image.
Step-by-step explanation:
y = - 3 - 2x
y = - 3 - 2( - 5)
y = - 3 + 10
y = 7
y = - 3 - 2( - 2)
y = - 3 + 4
y = 1
y = - 3 - 2( - 1)
y = - 3 + 2
y = - 1
y = - 3 - 2(2)
y = - 3 - 4
y = - 7

Sindy bought a pair of jeans with a price tag of $68.00. She paid 8% sales tax. How much sales tax did she pay and what was her final price including tax?
Answer:
Step-by-step explanation:
Sindy paid $5.44 in sales tax, and her total price was $73.44.
Sales Tax: 68 x .08= 5.44
Final Price: 68 + 5.44= 73.44
Answer:
To find sales tax, you need to find the percent of;
$68.00 * 8%
$68.00 * 0.08
= $5.44
$5.44 is the sales tax
Add the sales tax to the original amount:
$68.00 + $5.44 = $73.44
So the final price including tax is equal to $73.44.
