1/2 divided by 3/4= 1/a multiplied by b/c = d/e
Answers
Answer:
\( \frac{1}{2} \div \frac{3}{4} = \frac{1}{a} \times \frac{b}{c} \\ \frac{1}{2} \times \frac{4}{3} = \frac{1}{a} \times \frac{b}{c} \\ \)
So,
\(a = 2 \\ b = 4 \\ c = 3\)

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.

Find the mean of the integers: 17, -25, 3, -29, -15, 7
Answers
Answer: -7
Step-by-step explanation: To find the mean, here is the equation =
Divide the sum of all values in a data set ÷ the number of values = mean (average)
Step 1 :
So we do =
17 + -25 + 3 + -29 + -15 + 7 = -42
So the sum of the integers is -42
Step 2 :
We divide the sum by the number of values.
17, -25, 3, -29, -15, 7
1 2 3 4 5 6
So there are 6 values.
We do =
-42 ÷ 6 = -7
So the mean (average) of these integers is -7

A box contains several copies of Mrs. Spencer's new pamphlet. The box weighs 2,000 grams. This chart shows the effect of adding or taking away a pamphlet. Pamphlets Added to the box(x) Effect on the Box's Weight (y) 0 0 1 6 2 12 3 18 Is this an example of continuous or discrete data? discrete continuous
Answers
Answer:
This example represents discrete data.
Step-by-step explanation:
Discrete data refers to information that can only take certain specific values. In this case, the number of pamphlets added to the box (x) can only take on integer values such as 0, 1, 2, 3. Similarly, the effect on the box's weight (y) is also given as specific values: 0, 6, 12, 18.
In contrast, continuous data would involve measurements that can take any value within a range, such as height, weight, or temperature.
Since the number of pamphlets added and the corresponding effect on the box's weight are presented as specific, separate values, the data in this example is considered discrete.

B $20.37
C $27.16
D $29.62
Answers
Answer: $29.62
Step-by-step explanation:
6.79 * 3 = 20.37
9.25 * 1 = 9.25
So, 20.37 + 9.25 = 29.62
Answer:
D
Step-by-step explanation:
(6.79*3)+(9.25*1)=29.62
we multiply the cost of shortening a pair of pants by the number of pants brought and the cost of a dress multiplied by the number of dresses to get our answer
Quincy created a the table of x and y values shown here.

y -6 -4 -2 0
Which equation represents the relationship between the x values and the y values in the table?
A y=x+7
By=6x-1
Cy=3x-9
Dy=2x-8
Answers
Answer:
D
Step-by-step explanation:
the answer is y=2x-8
just sub in the a number from the x column in the equation and whatever you get from that is what should b in the y column
all you need to do is plug the x and y values given in the table into the x and y of the equations
for example, if we used equation A. y=x+7 we would plug in our first set of x and y values: -6=1+7 but once you solve it you find it’s not true: -6≠8 so you know it isnt equation A
if we use equation D. y=2x-8 , plug in our values: -6=2(1)-8 it is true since 2-8=-6, giving us -6=-6

The Cooking Club made some pies to sell during lunch to raise money for a field trip. The cafeteria helped by donating three pies to the club. Each pie was then cut into six pieces and sold. There were a total of 72 pieces to sell. How many pies did the club make?
Answers
Answer:
The answer is 10 pies. If each pie is cut into 6 slices, then all you have to do is divide 72 by six. The answer would be twelve. Because two of those pies were not made by the club, the answer is 10 pies
Step-by-step explanation:
your welcome can i have brainliest?
There are 9 pies that the club needed to make.
Since we have given that
Number of pies = 4
Number of pieces cut from each pie = 7
So, total number of pieces they needed = 91
Number of pieces from 4 pies =
so, Number of pieces the club needed to make is given by
Since each pie is cut into 7 pieces.
And number of extra pieces needed = 63

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answers
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.

Answer:

Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G
\(\frac{J-I}{G} = H\) >Answer is A
