so 4 weeks
4x2=8
8 more so 8+12=20
20 +((9-6)x2)=20+(3x2)=26
Answer:
1. 20 in
2. 26 in

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.
Match each equation with a solution from the list of values.

All the parts are solved below.
What is a function? What is equation modelling? What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the functionEquation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given are the equations -
1. 2a=4.6
2. b+2=4.6
3. c÷2=4.6
4. d−2=4.6
5. e+38=2
6. 18f=3
7. g÷85=1
We have -
[1] -
2a = 4.6
a = 2.3
[2] -
b + 2 = 4.6
b = 2.6
[3] -
c ÷ 2 = 4.6
c x 1/2 = 4.6
c = 4.6 x 2
c = 9.2
[4] -
d − 2 = 4.6
d = 6.6
[5] -
e + 38 = 2
e = - 36
[6] -
18f = 3
f = 3/18
f = 1/6

g ÷ 85 = 1
g x 1/85 = 1
g = 85

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

Jillian and Dawn are playing a game of miniature golf. In this game, the score on a hole is the number of putts it takes to get the ball into the hole. The winner is the player with the lowest score. After playing 18 holes, Jillian’s mean is 2.4 and Dawn’s mean is 3.3. Which explains who won the game?
Jillian won the game because her score varied less than Dawn’s score.
Jillian won the game because the person with the lower mean took fewer putts on average for each hole.
Dawn won the game because the person with the greater mean played better.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

A car traveled 35 miles in 2 hours. At this rate, how many miles will the car travel in ½ hour? ( i need this quick pls ! )
Answers
Answer:
8.75 miles
Step-by-step explanation:
1. First, make 35 miles = 2 hours.
35 miles = 2 hours
2. Next, since you know that 1/2 of an hour is 1/4 of two hours. So...
1/2 hour = 1/4 * 2 hour
3. So, 1/4 of 35 = 1/2 of an hour.
since 1/4 * 2 = 1/2
1/4 of 35 = 1/2 of an hour
4. Finally 35/4 = 8.75
So the answer is 35/4 or 8.75
At this rate, the car will travel 8.75 miles in ½ hour.
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that;
35 miles = 2 hours
Since we know that 1/2 of an hour is 1/4 of two hours.
So,
1/2 hour = 1/4 x 2 hour
So, 1/4 of 35 = 1/2 of an hour.
Since 1/4 x 2 = 1/2
1/4 of 35 = 1/2 of an hour
Finally 35/4 = 8.75
So, the answer is 35/4 or 8.75

For the first sum you nee to find the same coefficient or add or subtract a number
\(-x^3 -2x -7\)
This the simplified version of the sum above. I have basically subtracted -2x^3 by x^3 to make -x^3. Then I have subtracted -3x and x to make -2x. Finally I have added -4 and -3 as the rule suggests to add two numerals the minus symbol on both of them.
The next sum we have to simplify both numerals so we know if both sum’s answer are
\(-x^3 -2x -7-x^3 -2x -7\)
After simplifying them, both of them have the same answer, so the statement is true. To explain this, we could say that the sums were basically rotated around to trick us but the answer is still the same
