Tell if it wrong or right and help me in the last one if its wrong solve it

Answers

Answer 1

Answer: E is wrong. It only says twelve but it is a square and squares have the same side so u would really do twelve times twelve and get 144. And also I got 360 on the challenge one because u would split the irregular figure and you would do ten times nine equals ninety then nine times thirty equals 270. Then add it and you old get 360 m2

Answer 2

Answer: ok i'll help u
c is wrong
and the rest are right

If m∠A=(3x)∘and m∠D=(x+60)∘,what value of xmakes ABCD a parallelogram?

Enter the correct value of x.

Answers

Answer:

Step-by-step explanation:

Adjacent angles of a parallelogram add up to 180 degrees, meaning that (3x)+(x+60)=180 degrees. You can use this to set up the following equation:

3x+x+60=180

4x=120

x=30 degrees. Hope this helps!

Final answer:

In a parallelogram, opposite angles are equal. Therefore, set 3x (angle A) equal to x + 60 (angle D). Solving for x, we get x = 30.

Explanation:

In this case, we're working with a parallelogram, and one of the properties of a parallelogram is that its opposite angles are equal. That means that ∠A is equal to ∠D. So we set (3x) equal to (x + 60).

To determine the value of x, we can solve this equation:
3x = x + 60. Subtract x from both sides to get 2x = 60, then divide by 2 to get x = 30.

So, the value of x that makes ABCD a parallelogram is 30.

Please help fast! Sherman deposited $3000 in an account paying 8% interest compounded annually. He withdrew his money and interest 3 years later. How much did he withdraw?

Answers

The formula A = P (1 + r) ^ t will help, given that
A = the future value at withdraw
P = the initial deposit
r = the annual interest rate (decimal)
t = the number of years the money is invested for
so the equation is A = 3000 (1.08) ^ 3, which is $3779.14

He withdrew $3720. Use the formula I ( interest)= prt (principle, rate, time), and then add the interest earned to what he originally deposited.

the incredible chocolate chip company has discovered that 36 out of 400 chocolate chip cookies do not contain enough chocolate chips what percent of the chocolate chip cookies do not have enough chips

Answers

Use words to create an equation. 36 is what percent of 400? When you see the word "is", think of that as an equals sign. When you see "what percent", place a % sign. When you see the word "of", remember to multiply. So, the equation is % * 400 = 36. To solve, divide 36 by 400 to get 0.09 which is 9%. 36 cookies is 9% of 400 cookies. 9% of the chocolate chip cookies do not have enough chips.
