Use the models below to help you.


A. 1

B. 4

C. 6

D. 7

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.

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)

Answer:

The expressions that are equivalent are A, D, and E.

Step-by-step explanation:

Given:

-7z+ ( - 6.5) + 3.5z + 6y - 1.5.

On solving the equation:

[tex]-7z+ ( - 6.5) + 3.5z + 6y - 1.5[/tex]

[tex]-7z - 6.5+ 3.5z + 6y - 1.5[/tex]

[tex]-7z  + 3.5z + 6y - 1.5-6.5[/tex]

[tex]-3.5z+6y-8[/tex]

So, on solving the equation we get the expression:

[tex]-3.5z+6y-8[/tex]

According to question:

We see that expressions:

A. [tex]-8+6y+(-3.5z)[/tex]

   [tex]=-8+6y-3.5z = 3.5z+6y-8[/tex]

So, this expression is equivalent.

D. [tex]6y-8-3.5z[/tex]

   [tex]=3.5z+6y-8[/tex]

So, this expression is also equivalent.

E. [tex]-3.5z+6y-8[/tex]

So, this expression is also equivalent.  

Therefore, the expressions that are equivalent are A, D, and E.

The missing figure of the given line is attached

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 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]

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:

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:

Step-by-step explanation:

Solve for the quantity of flour using a proportion.

let 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.

Answer:

the ASA which is B. proves that the two triangles are congrugent

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.

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:

Therefore, to make 18 cups of juice, you'll need approximately 2 cups of concentrate and 16 cups of water.

27 vests

Step-by-step explanation:

       1 vest --------- 2/3 yard

       x vest -------- 18 yards

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.

Answer:

Step-by-step explanation:

In each triangle, the longest side is opposite the largest angle, and the shortest side is opposite the smallest angle.

Calculate a measure of an angle A.

We know: The sum of the angle measures in a triangle is 180°.

Therefore:

m∠A = 180° - (46° + 62°) = 180° - 108° = 72°

m∠B = 62°

LB is opposite ∠A, LA is opposite ∠B.

m∠A > m∠B → LB > LA.

Therefore Ship B is further away.
