$3.55 ÷ 5 = .71 each peach
To find out how much Tomas paid for each fruit, we set up the equation m = $3.55 / 5, which when solved gives m = $0.71. This means that Tomas paid $0.71 for each peach.
Explanation:To find out how much Tomas paid for each peach, you can set up an equation. Because Tomas buys 5 peaches for $3.55 in total, you can express this as a simple division. To solve the equation, divide $3.55 (total cost) by 5 (total number of peaches).
So, the equation would be m = $3.55 / 5.
Solving this equation gives: m = $0.71. Therefore, Tomas paid $0.71 for each peach.

Corbin’s parents want to save $50,000 for his college education and already have $25,000. About how long would it take them to double their current savings if they can earn an 8% interest rate?
Answer:
about 9 years
Explanation:
To solve this problem we will use what is known as 'The Rule Of 72.' This particular rule is what the Mathematical World considers a 'short cut.' That's because it is an efficient way to calculate how long it takes money to double, base solely on the interest rate. However, it is important to remember that this rule only provides an estimate, and not an exact amount of years.
The Rule Of 72 is as follows:
[tex]\displaystyle\frac{72}{[interest][rate]}[/tex] = time it takes for investment to double
*please note that I separated the word 'interest' and 'rate' using brackets. however, please ignore them. as I only used the brackets to separate the words since the equation option does not allow space between letters.
Now that you understand the Rule Of 72, let's use it to solve the given problem.
Corbin’s parents want to save $50,000 for his college education and already have $25,000. About how long would it take them to double their current savings if they can earn an 8% interest rate?
Although the first sentence in the problem gives us information of the parents goal and their current amount saved, this information will not be useful to us. As the Rule Of 72 goes, we only need to know the interest rate to solve.
Looking at the second sentence it states the interest rate is: 8%
Now substitute the interest rate in the Rule Of 72.
[tex]\displaystyle\frac{72}{[interest][rate]}[/tex] ⟶ [tex]\displaystyle\frac{72}{8}[/tex]
The last step is to simplify (or divide).
[tex]\displaystyle\frac{72}{8} = 9[/tex]
So, according the Rule Of 72, it will only take about 9 years to double their current savings.

9 years

you mix 0.25 cup of juice concentrate for every 2 cups of water to make 18 cups of juice. how much juice concentrate do you use? how much water do you use ?
Answer:
You have a total of 2.25 cups of liquid each time you add 2 cups of water with .25 cups of concentrate.
You want to know how many times 2.25 cup "units" there are in 18 cups.
(18)/(2.25) = 8, so you have 8 "units" of water and concentrate
In each of those 8 "units" you have .25 cups concentrate, so (8)(.25) = 2 cups of concentrate.
In each of the "units" you have 2 cups of water, so (8)(2) = 16 cups water.
Please let me know if you have any questions.
Step-by-step explanation:
To make 18 cups of juice, you'll need approximately 2 cups of concentrate and 16 cups of water given the ratio of the recipe.
Explanation:To answer your question, we need to solve a proportion problem.
The recipe's ratio is 0.25 cups of juice concentrate to 2 cups of water. This means for every 0.25 cups of concentrate, you add 2 cups of water to get 2.25 cups of juice.
Since you want to make 18 cups of juice, you can set up a proportion:
0.25:2=concentrate:water 2.25/0.25=18/x(x=concentrate) Cross-multiply and divide to find x= 2(approx)
Therefore, to make 18 cups of juice, you'll need approximately 2 cups of concentrate and 16 cups of water.

A pancake recipe requires one and one third cups of milk to one cup of flour. If four and two thirds cups of milk is used, what quantity of flour will be need
according to the recipe?
Final answer:
According to the recipe, 3.5 cups of flour will be needed when using 4 and 2/3 cups of milk.
Explanation:
To determine the quantity of flour needed according to the recipe, we can set up a proportion using the given ratios. The recipe states that 1 and 1/3 cups of milk is needed for 1 cup of flour. So, we can set up the proportion:
1 and 1/3 cups of milk / 1 cup of flour = 4 and 2/3 cups of milk / x cups of flour
Next, process is to cross-multiply and find x:
Therefore, according to the recipe, 3.5 cups of flour will be needed when using 4 and 2/3 cups of milk.
Answer:
Three and a half cups of flourStep-by-step explanation:
Solve for the quantity of flour using a proportion.
Milk to flour ratioslet x be the missing quantity of flour
Recipe ratio is 1 1/3 to 1
Needed ratio is 4 2/3 to x
Write each milk to flour ratio as a fraction. Equate them, and they become a proportion:
[tex]\dfrac{1\dfrac{1}{3} }{1} = \dfrac{4 \dfrac{2}{3} }{x}[/tex]
Find the scale factor for the increase of milk by dividing the needed quantity by the recipe quantity .
Divide 4 2/3 by 1 1/3:
[tex]4\dfrac{2}{3} \div 1\dfrac{1}{3}[/tex]
[tex]=\dfrac{14}{3} \div \dfrac{4}{3} = \dfrac{14}{3} * \dfrac{3}{4}[/tex]
[tex]= \dfrac{42}{12} = \dfrac{7}{2} = 3.5[/tex]
The scale factor is 3.5.
The scale factor for increasing milk is the same for flour. Multiply the recipe quantity of flour by the scale factor to get the needed quantity of flour.
Multiply 1 by 3.5:
1 * 3.5 = 3.5
We will write this in word form, just as it is in the question.
Therefore, we need three and a half cups of flour when there are four and two-thirds cup of milk.

Mrs. Smith’s class is making vests. Each vest uses 2/3 of a yard of fabric. How many vests can they make out of 18 yards of fabric?
Answer:
27 vests
Step-by-step explanation:
If a vest is made out of 2/3 yard of fabric, then to know how many vest can be made with 18 yards, of fabric, we apply simple three rule, like this:1 vest --------- 2/3 yard
x vest -------- 18 yards
Then, to know how many vest can be made out of 18 yards of fabric ("x"), we divide 18 by (2/3): [tex]\frac{18}{\frac{2}{3}} =18\frac{3}{2} =24[/tex].Final answer:
Mrs. Smith's class can make 27 vests out of 18 yards of fabric by dividing the total yards of fabric by the fabric needed for one vest, i.e., dividing 54 thirds of fabric by 2 thirds per vest.
Explanation:
The student's question involves a practical application of division in mathematics, specifically the division of fractions. To determine how many vests can be made from 18 yards of fabric, we need to divide the total yards of fabric by the amount of fabric needed for each vest.
Since each vest uses 2/3 of a yard of fabric, and Mrs. Smith has 18 yards of fabric, we can set up the following equation to find the number of vests:
Convert 18 yards to thirds to match the unit in the vest requirement. (18 yards * 3 thirds) = 54 thirds.
Divide the total thirds of fabric by the thirds needed for one vest. (54 thirds ÷ 2 thirds per vest) = 27 vests.
Therefore, Mrs. Smith's class can make 27 vests out of 18 yards of fabric.

What is the area of a circle with a diameter of 4x - 24? Specifically what steps would you take?
Answer:
12.56x^2+452.16
Step-by-step explanation:
A=pie r^2
(4x-24)/2= 2x-12 which is your radius
(2x-12)^2=4x^2+144
Pie=3.14ish
3.14(4x^2+144)
12.56x^2+452.16
Answer:
Step-by-step explanation:
The formula for the area of a circle is
A = πr². We need the radius, r, to calculate the circle.
If the diameter of the circle is 4x - 24, then the radius is half that, or
2x - 12.
Then the area of the circle in question is A = πr², or
A = π(2x -12)²
If desired, this could be expanded:
A = π(4)(x - 6)² = 4π(x^2 -12x + 36)

The equation in the point-slope form of the line is [tex]y+3=\frac{1}{4}(x+4)[/tex] ⇒ 3rd answer
Step-by-step explanation:
The relation between the perpendicular lines
The product of their slopes is -1If the slope of one of them is m, then the slope of the other is [tex]\frac{-1}{m}[/tex]The formula of the slope of a line is [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
The point-slope form of the equation of a line is [tex]y-y_{1}=m(x-x_{1})[/tex] , where [tex](x_{1},y_{1})[/tex] is a point on the line
From the attached figure
The given line passes through points (-1 , 1) and (0 , -3), use them to find the slope of the line
∵ [tex]x_{1}[/tex] = -1 and [tex]x_{2}[/tex] = 0
∵ [tex]y_{1}[/tex] = 1 and [tex]y_{2}[/tex] = -3
∴ The slope of the given point = [tex]\frac{-3-1}{0-(-1)}=\frac{-4}{1}=-4[/tex]
∵ The product of the slopes of the perpendicular lines is -1
∵ The slope of the given line = -4
- Reciprocal the number and change its sign
∴ The slope of the perpendicular line = [tex]\frac{1}{4}[/tex]
∵ The slope-form of the equation is [tex]y-y_{1}=m(x-x_{1})[/tex]
∵ [tex]m=\frac{1}{4}[/tex]
∵ The line passes through point (-4 , -3)
∴ [tex]x_{1}[/tex] = -4 and [tex]y_{1}[/tex] = -3
- Substitute these values in the form of the equation
∴ [tex]y-(-3)=\frac{1}{4}(x-(-4))[/tex]
∴ [tex]y+3=\frac{1}{4}(x+4)[/tex]
The equation in the point-slope form of the line is [tex]y+3=\frac{1}{4}(x+4)[/tex]
