Use your calculator to the square root of 125.

The answer is 11.180...... and so on. But we just leave it as 11. Therefore, 11 and 11 are equal. That's the answer to your question.

The cost of meal = [tex]$30[/tex]

The tip to the waiter = [tex]8%[/tex]%

Step-by-step explanation:

One angle of a nonagon has an angle of 140 degrees, so

7x = 140.

Divide 140 by 7 to find the value of x.

140 ÷ 7 = 20

Step-by-step explanation:

1 + 0.02 is the 2% growth of the collection every month, to the power of 12 means the 12 months, and to the power of 2 mean 2 years.

[tex]\qquad \textit{Amount for Exponential Decay} \\\\ A=P(1 - r)^t\qquad \begin{cases} A=\textit{current amount}\dotfill &\stackrel{40\%~of~P}{0.4P~~~~}\\ P=\textit{initial amount}\dotfill &P\\ r=rate\to 22.5\%\to \frac{22.5}{100}\dotfill &0.225\\ t=\textit{elapsed time}\\ \end{cases} \\\\\\ 0.4P=P(1-0.225)^t\implies \cfrac{0.4P}{P}=(1-0.225)^t\implies 0.4=0.775^t[/tex]

[tex]\log(0.4)=\log(0.775^t)\implies \log(0.4)=t\log(0.775) \\\\\\ \cfrac{\log(0.4)}{\log(0.775)}=t\implies \stackrel{\textit{about 3years, 215days and 8hrs}}{3.59\approx t}[/tex]

so at that time the value is 40% of its original value, I guess is less than that a minute or an hour later.

Associative Property of Addition

Step-by-step explanation:

Answer:

If I am correct both figures are similar because of AA (angle reasoning). They have the same angles meaning they are similar triangles even if they don't fit the SSS, SAS, etc. reasoning

Step-by-step explanation:

You could also do the cross multiply divide method to determine if they equal the corresponding length (which they do!) hope this helps! :)

edit: Question 4) is similar following the AA statement for triangles

Question 5 is not similar because it doesn;t match doing the cross multiply divide and has two right angles because they are

rectangles!

Question 1) Corresponding angles are related in two similar figures because they are the same. In triangles two figures similarity can be determined by identifying if they share two angles.

Question 2) Corresponding side lengths can determine the similarity by proving that the shape was only transformed by a scale factor and did not alter shape.

Question 3) No, not neccesarily. If they are the same size, length, and shape they are congruent. Similar figures are altered and different based on a scale factor

Answer:

Measure of each angle is 71 and 19 degrees.

Step-by-step explanation:

Let's the angle  be "n"

Complementary angle = 90 °

n- (90-x) = 52

n - 90+ n = 52

Combine like terms

n - 90+ n = 52

2n-90=52

Add 90 to both sides of the equation

2n-90+90=52+90

simplify

2n = 142

Divide both sides of the equation by the same term

2n/2 = 142/2

Simplify

n = 71

2n = 142

Measure of each angle

1st = 71

2nd = 90-71 = 19

50,646

Step-by-step explanation:

Jim would have saved 50,646 in 4 years

Jim will have $5,149,010 in 4 years.

Simple interest is a method for figuring out how much interest was paid on a sum of money during a specific time period at a specific rate. Simple interest has a constant principle amount. Simple interest is a clear-cut and simple method for computing financial interest.

We have,

P = $84,410.

R= 15%

T = 4 years

Using Simple Interest

SI = (P x R x T) / 100

SI = (84410 x 15 x 4)/100

SI = 5,064,000

So, the amount is

= 84,410 + 5,064,000

= 5,149,010

Answer:

(3,2)

Step-by-step explanation:

2x-4=y

2y+3x=13

We substitute the y in. They already gave us the equation 2x-4=y simplified so you would just plug this into the other equation

2(2x-4) +3x=13 : *distribute*

4x-8+3x=13 :  *combine like terms*

7x-8=13  * add the 8 to the other side*

7x=21 *divide*

x=3

So  the y=2x-4 is what we added in the place of the y to subtract it and solve for x. The second step would be solving for y. So now that we have our answer, 3  we plug it into the other equation preferably.

2(3)-4 =y : 6-4=y : 2=y

We can check our answer by pugging both x and y into both equations to make sure they are right. The statement should be true.

2x-4=y         2(3)-4=(2)    2=2

2y+3x=13    2(2)+3(3)=13    13=13

The amount of money returned as interest depends on the initial

amount, the interest rate and the number of years.

Response:

Given:

The return on investment = $6,336

Amount the Certificate of Deposit pays = 4.4% simple interest

The initial investment (the principal), P= $16,000

Required:

The duration the initial amount of money had been invested.

Solution:

Interest = Principal × Rate × Time

Which gives;

[tex]Time = \mathbf{ \dfrac{Interest }{ Principal \times Rate}}[/tex]

Therefore;

Hope this helps.

Seven boys hire DVD's and each pays R5,50

I assume R 5.50 ( R to be the currency)

also assuming that they dont hire any more DVDs

total amount paid by 7 boys

= 5.50 × 7

= 38.5

when 4 more friends join the amount should get divided by 11 ( 7 + 4 )

so each has to pay an amount of 38.5 / 11 = 3.5
