Answer:Kim’s family invested $3000

Step-by-step explanation:

The value of the CD will be an amount of $7487.01 if it is compounded annually for 15 years.

Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.

To find the value of the CD in 5 years, you need to calculate the compound interest earned over 5 years.

The interest rate is 8% per year, so the interest rate per quarter is 8% / 4 = 2%.

The value of the CD at the end of each quarter can be calculated using the formula:

CD value at end of quarter = CD value x (1 + interest rate per quarter)

For example, at the end of the first quarter, the CD value would be:

CD value at end of first quarter = $3000 x (1 + 0.02) = $3060

You can repeat this process for each quarter to find the CD value at the end of 5 years.

After 5 years, there will have been 20 quarters (5 years x 4 quarters per year), so the CD value at the end of 5 years will be:

CD value at end of 5 years = $3000 x (1 + 0.02)²⁰ = $4393.84

To find the value of the CD if it is compounded annually for 15 years, you can use the same formula, but use the annual interest rate of 8% and the number of years of 15. The CD value at the end of 15 years will be:

CD value at end of 15 years = $3000 x (1 + 0.08)¹⁵ = $7487.01

Answer:

90,000

Step-by-step explanation:

As per the given scatter plot, for the cost of $180, the number of gallons of water used is 90,000.

The association between two numerical variables measured for the same individuals is displayed in a scatterplot. One variable's values are displayed on the horizontal axis, and the other variable's values are displayed on the vertical axis.

Here,
According to the question, the maximum limit shown on the scatterplot is $180 for 90 units on the scatterplot,
Where horizontal units are represented as the scale of 1 unit = 1000 units.
So for the maximum.
For the cost of $180 the gallons of water used is 90×1000.

Thus, as per the given scatter plot, for the cost of $180, the number of gallons of water used is 90,000.

Answer:  Piper will have $3750  

Step-by-step explanation:

In this situation we will represent the total amount she have in the bank by y and the number of weeks by x

The whole situation can be represented by the the equation

  y = 1400 + 50x  where y is the total amount , 1400 is the initial amount Piper deposited , 50 is of course the amount Piper will deposit each week , and x is the number of weeks.

Now since they are looking for the amount Piper will have in his account, you have to input 47 for x and solve for y.

y = 1400 + 50(47)

y = 1400 + 2350

y = 3750

Answer:

is a required equation. but I forgot to show that it passes through the origin.sorry for that.we had done in previous grade.

FORMULA FOR COMPOUND INT. = A = P ( 1 + [tex]\frac{R}{100}[/tex])[tex]^{n}[/tex]

= P = 2000, R = [tex]\frac{5}{12}[/tex] ( as it is compounded monthly ), N= 8 × 12 = 96

= A = 2000 [tex]([/tex] 1 + [tex]\frac{5}{1200}[/tex] [tex])^{96\\}[/tex] = [tex]\frac{2000}{1}[/tex] × ([tex]\frac{1205}{1200}[/tex]) [tex]^{96}[/tex]

Answer:

The value of n = 4 and  

The value of x = [tex]\frac{5}{3}[/tex]

Step-by-step explanation:

Method I:

As given, 12x -20=n (3x-5)      .........(1)

Firstly , take 12x - 20

As 12x - 20 can be written as 4(3x - 5)

∴ equation (1) becomes

4(3x - 5) = n (3x-5)

Divide the equation by (3x-5) , we get

4 = n

Method II:

As given, 12x -20=n (3x-5)

⇒12x - 20 = 3nx - 5n

⇒12x - 3nx = 20 - 5n

⇒3x(4 - n) = 5( 4 - n)

Divide the equation by (4-n) , we get

3x = 5

⇒ x = [tex]\frac{5}{3}[/tex]

∴ we get

n = 4 and  x = [tex]\frac{5}{3}[/tex]

Now, check that value of n and x satisfies the equation or not

12([tex]\frac{5}{3}[/tex]) - 20 = 4( 3([tex]\frac{5}{3}[/tex]) - 5)

⇒4(5) - 20 = 4(5 - 5)

⇒20 - 20 = 4(0)

⇒ 0 = 0

Hence , we get

The values of x and n satisfies the equation

so, we get

n = 4 and  x = [tex]\frac{5}{3}[/tex]

Step-by-step explanation:

When you multiply radicals, you do the following

[tex]\sqrt{20}\cdot 5\sqrt{2}\\\\\longrightarrow 20 = 2^2\cdot 5\\\\=2\sqrt{5}\cdot5\sqrt{2}\\\\=(2\cdot5)\sqrt{5\cdot2}\\\\=10\sqrt{10}[/tex]

12x+1=3(4x+1)−2

Step 1: Simplify both sides of the equation.

12x+1=3(4x+1)−2

12x+1=(3)(4x)+(3)(1)+−2(Distribute)

12x+1=12x+3+−2

12x+1=(12x)+(3+−2)(Combine Like Terms)

12x+1=12x+1

12x+1=12x+1

Step 2: Subtract 12x from both sides.

12x+1−12x=12x+1−12x

1=1

Step 3: Subtract 1 from both sides.

1−1=1−1

Answer:

1) A, 2) A, 3) B, 4) D, 5) A, 6) proportion, 7) 4 : 3, 8) a) The simplest ratio of 14 : 42 is 1 : 3, b) The simplest ratio of 56 : 80 is 7 : 10, 9) a) The series 4, 6, 8, 12 is in proportion, since each element after the first one is equal to the sum of the previous element and 2 units, b) The series 15, 45, 5, 25 is not in proportion, since it is an alternating series, 10) 4 cans of juice cost 140, 11) a) 3 : 2, b) 3 : 1, 12) The ratio of 15 centimeters to 2 meters is 3 : 40.

Step-by-step explanation:

1) The ratio is determined by following operation:

[tex]x = \frac{300}{100}[/tex]

[tex]x = \frac{3}{1}[/tex]

3 : 1 is the ratio of 300 to 100. (Answer: A)

2) The weight of 1 book is found by the total weight of books divided by the total amount of books, that is:

[tex]x = \frac{80\,kg}{20}[/tex]

[tex]x = 4\,kg[/tex]

The weight of 1 book is 4 kilograms. (Answer: A)

3) The equivalent ratio of 3 : 2 is found by multiplicating both numerator and denominator by a given positive number:  

[tex]x = \frac{3\times 2}{2\times 2}[/tex]

[tex]x = \frac{9}{4}[/tex]

An equivalent ratio of 3 : 2 is 6 : 4. (Answer: B)

4) The middle terms of ratio correspond with the denominator of the ratio on the left and the numerator of the ratio on the right. Hence, the middle terms of 3 : 15 = 21 : 105 are 15 and 21. (Answer: D)

5) 8 : 4 is not proportional to 8 : 16, since both numerators and denominators are not multiplied by the same number. That is:

[tex]x = \frac{8\times 1}{4\times 4}[/tex]

[tex]x = \frac{8}{16}[/tex]

8 : 4 :: 8 : 16 is not proportional. (Answer: A)

6) If two ratios are equal, then they are in proportion. That is:

[tex]a \,:\,b \,::c\,:\,d[/tex], where [tex]r = \frac{c}{a} = \frac{d}{b}[/tex], [tex]\forall\,r > 0[/tex].

If two ratios are equal, then they are in proportion. (Answer: proportion)

7) The ratio of 20 boys to 15 girls is derived of 20 divided by 15 until a denominator of the least integer is found by simplifying the fraction:

[tex]\frac{20}{15} = \frac{4}{3}[/tex]

The ratio of 20 boys to 15 girls is 4 : 3. (Answer: 4 : 3)

8) Express the following ratios in the simplest form:

a) [tex]\frac{14}{42} = \frac{7}{21} = \frac{1}{3}[/tex].

The simplest ratio of 14 : 42 is 1 : 3.

b) [tex]\frac{56}{80} = \frac{28}{40} = \frac{14}{20} = \frac{7}{10}[/tex]

The simplest ratio of 56 : 80 is 7 : 10.

9) When a series is in proportion, it must be in increasing or decreasing order at constant rate.

a) The series 4, 6, 8, 12 is in proportion, since each element after the first one is equal to the sum of the previous element and 2 units.

b) The series 15, 45, 5, 25 is not in proportion, since it is an alternating series.

10) We determine the cost of 4 cans of juice by simple rule of three:

[tex]x = \frac{4\,cans}{6\,cans}\times 210[/tex]

[tex]x = 140[/tex]

4 cans of juice cost 140.

11) a) The ratio of her earning to her expenditure is:

[tex]x = \frac{150000}{150000-50000}[/tex]

[tex]x = \frac{3}{2}[/tex]

The earning to expenditure ratio is 3 : 2.

b) The ratio of her earning to her savings is:

[tex]x = \frac{150000}{50000}[/tex]

[tex]x = 3[/tex]

The earning to savings ratio is 3 : 1.

12) 1 meter equals 100 centimeters. Then, the given ratio is:

[tex]x = \frac{15\,cm}{200\,cm}[/tex]

[tex]x = \frac{3}{40}[/tex]

The ratio of 15 centimeters to 2 meters is 3 : 40.

Step-by-step explanation:

Add the areas of the individual shapes so one rectangle and a square.

4*2 + 5*5 > 8 + 25 = 33

Answer:

31 cm²

Step-by-step explanation:

The area of the large figure is the sum of the areas of the smaller rectangles, the 4 cm x 2 cm one and the 5 cm x 5 cm one.

Area of the 4 x 2: 4 x 2 = 8 cm²

Area of the 5 x 5: 5 x 5 = 25 cm²

Sum of the two: 8 cm² + 25 cm² = 31 cm²
