Answer:

3 x (3 + 12 divided by 3) - 4

Do the division first in the parentheses and you get 4.

Do 3 + 4 and that will give you 7.

Do 7 x 3 and that will give you 21.

Then do 21 - 4.

21 - 4= 17.

Therefore, 17 is your answer

What should be done to solve the following equation?

x - 9 = 13

Add 9 to both sides of the equation.
Subtract 9 from both sides of the equation.
Subtract 13 from both sides of the equation.
Add 9 to the left side of the equation.

Answers

add 9 to both sides. if you’re trying to find x you need to isolate it and in doing so you have to reverse the -9 by adding 9
if you are trying to find x, you add nine to both sides of the equation.

Look at the rectangle and the square:

A rectangle PQRS and square LMNO are drawn side by side. The length SR of the rectangle is labeled as 12 inches, and the width QR is labeled as 6 inches. The side LM of the square is labeled as 6 inches
Sam says that the length of diagonal SQ is two times the length of diagonal OM.

Is Sam correct? Justify your answer and show all your work. Your work should state the theorem you used to find the lengths of the diagonals.

Answers

Answer:

False

Step-by-step explanation:

Let's consider the triangle SQR. We know it is right-angle because part of the rectangle PQRS. We can use the Pythagorean theorem:

[tex]SQ^{2} = RQ^{2} + SR^{2} \\SQ^{2} = 36 + 144 = 180\\SQ = \sqrt{180} = 13,4[/tex]

We can do the same for the square in which ON = 6 because it's a square:

[tex]OM^{2} = MN^{2} + ON^{2} \\OM^{2} = 36 + 36 = 72\\OM = \sqrt{72} = 8.5[/tex]

Now let's compare them:

8.5 X 2 = 17 so OM X 2 is not equal to SQ

The sentence is false.

Find the period.
Principal = 9300 rupees
Annual rate of interest = 13%
Total amount = 17,763
Period = _____ years

Answers

Answer:

The Time period of the Amount is 5 years 3 days .

Step-by-step explanation:

Given as :

The principal = p = Rs 9300

The annual rate of interest = r = 13%

The Total amount after t years = A = Rs 17,763

Let The time period = t years

From Compound Interest method

Amount = principal ×  

Or, A = p ×  

Or, Rs 17,763 = Rs 9300 ×  

Or,  =  

or, 1.91 =  

Taking Log both side

1.91 = (   )

or, 0.2810 = t × 1.13

or, 0.2810 = t × 0.0530

∴ t -  

I.e t = 5.30 years

So, The time period = t = 5 years 3 days

Hence The Time period of the Amount is 5 years 3 days
