Answer:

[tex]\dfrac{1}{27}[/tex]

Step-by-step explanation:

Given that,

a-b = 3

We need to find the value of [tex]\dfrac{27^{\dfrac{1}{3}b}}{9^{\dfrac{1}{2}a}}[/tex].

We know that,

[tex]27=3^3\\\\9=3^2[/tex]

So,

[tex]\dfrac{27^{\dfrac{1}{3}b}}{9^{\dfrac{1}{2}a}}=\dfrac{3^3^({\dfrac{1}{3}b})}{3^2^{\dfrac{1}{2}a}}\\\\=\dfrac{3^b}{3^a}[/tex]

We know that : [tex]\dfrac{x^p}{x^q}=x^{p-q}[/tex]

So,

[tex]\dfrac{3^b}{3^a}=3^{b-a}[/tex]

Since, b-a = -3. So,

[tex]3^{b-a}=3^{-3}\\\\=\dfrac{1}{3^3}\\\\=\dfrac{1}{27}[/tex]

So, the value of the given expression is equal to [tex]\dfrac{1}{27}[/tex].

part A is 48.98 meters squared. part B is $288.982.

Step-by-step explanation:

To find the area of the flooring you multiply 7.9 and 6.2 which gives you 48.98 meters squared. Then for part B you take your product from part A and multiply it by $5.90, giving you $288.982.

Answer:

f=7x g=3   x=18

Step-by-step explanation:

Answer:

Person A paints the house in 12 days.

person B paints the house in 60 days.

Step-by-step explanation:

The together rate is the sum of each separate rate.

Person A can paint the neighbor's house 5 times as fast as Person B.

This means that the rate of person A is 1/x, and the rate of person B is 1/5x.

The year A and B worked together, it took them 10 days.

This means that:

[tex]\frac{1}{x} + \frac{1}{5x} = \frac{1}{10}[/tex]

Multiplying everything by 10x

[tex]10 + 2 = x[/tex]

[tex]x = 12[/tex]

This means that:

Person A paints the house in 12 days.

person B paints the house in 60 days.

Answer: Compounded quarterly, 350, 420, 25, the account pays interest on both the principal and the interest accumulated.

Step-by-step explanation:

Question 1: Compounded quarterly is growing fastest because it's broken down more than what simple interest does and therefore is faster instead.

Question 2: Account A in 30 years would be 350, I did this problem and eyeballed it. Trust me.

Question 3: Account B in 30 years would be 420.

Question 4: The approximate difference between the two accounts in 20 years would be 25.

Question 5: If the rate of interest is annual and the interest is compounded quarterly then the number of years is 4 times and the rate of annual interest is one-fourth. Therefore, the account pays interest on both the principal and the interest accumulated.

Hope this helps

The simple interest and compound interest are solved for both the curves

a) The compound interest is growing fastest

b) the amount in Account A in 30 years A = $ 350

c) The amount in Account B in 30 years is B = $ 420

d) The difference between the two accounts in 20 years = $ 25

Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.

The formula for calculating Compound Interest is

A = P ( 1 + r/n )ⁿᵇ

where A = Final Amount

P = Principal

r = rate of interest

n = number of times interest is applied

b = number of time periods elapsed

Given data ,

a)

Let the 2 curves be represented as A and B

Now , the amount invested by A = $ 200

The rate of simple interest = 2.5 %

And , the amount invested by B = $ 200

The rate of compound interest = 2.5 %

So , we can say that since it is more thoroughly broken down than basic interest is, compounded quarterly growth is the quickest.

b)

The amount for A in 30 years is given in the graph

A = $ 350

c)

The amount for B in 30 years is given in the graph

B = $ 420

d)

The amount for A in 20 years is given in the graph = $ 300

The amount for B in 20 years is given in the graph = $ 325

The difference between the two accounts in 20 years = $ 325 - $ 300

The difference between the two accounts in 20 years = $ 25

Hence , the compound interest is solved

Answer:

Your total will be $64.19

Step-by-step explanation:

I know this because 7% is $4.20 and so if i add $59.99 to $4.40 i will get $64.19:)

Step-by-step explanation:

You can call c the number of children and a of adults; you get:

5.20c+8.50a=1097.60

and

a=4c meaning that the number of adults was four times the children.

Substituting this value of a into the first equation we get:

5.2c+8.5(4c)=1097.6

5.2c+34c=1097.6

rearranging:

c=1097.639.2=28

and so:

a=4c=4⋅28

Answer:

b. 98

Step-by-step explanation:

May and June:

May: 223 Dinztop sales

June: 148 Dinztop sales.

So

[tex]p = \frac{148}{223} = 0.6637[/tex]

In June, it sold 0.6637 = 66.37% the amount of computers sold in May.

How many Dinztop computers will be sold in July?

Because of the same percent rate, 0.6637 = 66.37% of the amoutns sold in June.

0.6637*148 = 98

The correct answer is given by option b.

Answer:

do you have a picture of this

Answer:

width = 25 ft

Step-by-step explanation:

SA = 2lh + 2lw + 2wh

5278 = (2)(23)(43) + (2)(23)(w) + (2)(w)(43)

reduce:

5278 = 1978 + 46w + 86w

subtract 1978 from each side:

3300 = 132w

divide both sides by 132

w = 25

Answer:

If you are finding the area, then it would be 10 [tex]units^{2}[/tex]. But for the missing side it is probably I would say 7.

Answer:

Complementary angles

Step-by-step explanation:

When two angles add up to 90°, they are Complementary to each other.

Here, ∠DAB = 90° (right angles)

It means, ∠DAB = ∠BAE (vertically opposite angles)

Also, ∠BAE = a + b

So, a+b is equal to 90°. Hence, the correct option is (b) "Complementary angles".
