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.
5x-8y+9 what are the terms of the expression? what are the coefficients of the expression
Answer:
The coefficients are 5,8. The terms of expression are 5x, 8y and 9
Step-by-step explanation:
The coefficient for the equation is 5 and 8 as both of the numbers have a variable by its side (the letter x & y). Meanwhile the terms for the equation are 5x, -8y, and 9. This is because all those numbers have an operation symbol. Keep in mind that 5x, has a positive operation at the front of the number but it is not written to the equation to make it simpler. Hope this helps ease up your understanding.

Answer: 9/1 . or 9
Step-by-step explanation:
Conversion a mixed number 3 3/4 to a improper fraction: 3 3/4 = 3 3/4= 3 · 4 +3/4= 12 + 3/4 = 15/4
part 2
Conversion a mixed number 2 2/5to a improper fraction: 2 2/5 = 2 2/5= 2 · 5 +2/5= 10 + 2/5 = 12/5
part3
Multiple: 15/4 * 12/5 = 15 · 12/4 · 5 = 180/20= 9 · 20/1 · 20= 9
next intermediate step, , cancel by a common factor of 20 gives 9/1

Answer:A. 4 is greater than -2(4) + 6 = -8 + 6 = -2 which is correct
B. 0 is greater than -2(0) + 6 = 6
That statement is untrue.
C. 1 is greater than -2(1) + 6 = 4
That statement is untrue.
D. 2 is greater than -2(2) + 6 = 2
That statement is untrue.
Step-by-step explanation: The answer is A since after you plug in 4 for x and y, the statement 4 > -2 is true. 4 IS greater than -2.

On a map the scale showing is 1 inch by 5 mi if a park is 75 square miles what is the area of the park on the map. The parks area is _____ square inches on the map
Answer: 15 square Inches
Step-by-step explanation: I believe you should divide 75 and 5(75mi÷5mi=15in) to get 15in.
Answer: 3 square inches.
If the park is 25 square miles, it could be 5×5 miles. If the scale is 1 inch = 5 miles, that would be 1×1 inch or 1 square inch on the map. Since 75 is 3×25, it will be 3×1 square inches on the map.
Step-by-step explanation: Remember that the scale represents linear measurements. For area, you must square the linear "sides" to get the number of actual square units represented by a square unit on the map.

Tell whether ratios form a propotion
1/4; 3/12
54/10; 81/15
18/24; 15/20
someone help me pls:(
Answer: Ratios form a proportion if they are equal when cross-multiplied.
1/4 and 3/12
Cross-multiply these ratios to compare them: 1/4 * 12 = 3, 3/12 * 4 = 3.
So they are equal and form a proportion.
54/10; 81/15
Cross-multiply these ratios to compare them: 54/10 * 15 = 81, 81/15 * 10 = 54.
So they are equal and form a proportion.
18/24; 15/20
Cross-multiply these ratios to compare them: 18/24 * 20 = 15, 15/20 * 24 = 18.
So they are equal and form a proportion.
Hence, all the ratios mentioned above form a proportion.

Bud’s cheeseburger and fries contained 1310 milligrams and 350 milligrams of sodium, respectively. Together they contained 66.4% of the recommended daily intake of sodium for a 2,000 calorie diet. What is the daily recommended intake of sodium for a 2,000 calorie diet? Show your work.
The daily recommended intake of sodium for a 2,000 calorie diet is 2000 calorie diet is 2500 mg.
What is diet?Healthy diet:
A healthy diet helps protect against malnutrition in all its forms and is a foundation for health and development. It also helps to prevent noncommunicable diseases including diabetes, cardiovascular diseases, some cancers and other conditions linked to obesity.
In order to calculate the daily intake of sodium we first need to calculate the mass of sodium present in both snacks, this is given by their sum.
\(\text{Total sodium = 1310 + 350 = 1660}\)
We can now apply a rule of three for which the total sodium from the snacks is related to 66.4% in the same proportion as "x" mg, which is the value we want to know, is related to 100%. So we have:
\(\frac{1660}{x} \frac{mg}{mg} = \frac{66.4}{100} \\\\66.4*x = 1660*100\\x=\frac{166000}{66.4} = \bold{2500\text{ mg}}\)
Hence, the daily recommended intake of sodium for a 2,000 calorie diet is 2000 calorie diet is 2500 mg.

The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
