Answers

Answer:

You cant add them so it is probably a trick question.

Step-by-step explanation:

We would need to determine “u”
With PEMDAS, we would multiply 3 by u, and then add six.
If there is no u, variables are always at 1 by default. If there is absolutely no u, the answer would be 9.

solve for x with an explanation pls

Answers

Answer: 9

Step-by-step explanation:

Use Pythagorean's Theorem for a right triangle.

[tex]a^2+b^2=c^2[/tex]

[tex](\sqrt{63}) ^2+x^2=12^2\\63+x^2=144\\x^2=81\\x=9[/tex]

X=9

A squared + b squared = c squared

C is the hypotenuse (the side opposite of the right angle)

X*2 + square root of 63 squared = 12*2
Squaring 63 would cancel out with the square root. You are left with x*2 + 63 = 144. 144-63= 81. X*2=81 ; square root both sides. You are now left with x=9

The numbers 1-6 are written on slips of paper and placed in a bag. Megan draws two numbers in a row without replacement. What is the probability of Megan selecting an even number followed by a 3?

A) 1/6

B) 1/10

Answers

I’m pretty sure it would be 1/6

The probability of Megan selecting an even number followed by a 3 will be 1/10. Then the correct option is B.

What is probability?

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

Paper slips with the numbers 1-6 are collected in a bag. Without substitution, Megan draws two numbers consecutively.

The probability is given as,

P = (1/6) x (3/5)

P = (1/2) x (1/5)

P = 1/10

The probability of Megan selecting an even number followed by a 3 will be 1/10. Then the correct option is B.

More about the probability link is given below.

What is the prime factorization of 88?
A.8✖11
B.2✖4✖11
C.4✖4✖11
D.2✖2✖2✖11

Answers

The answer is d
Hope this helps :)

Answer:

D. 2✖2✖2✖11

Step-by-step explanation:

To get the Prime Factors of 88, you divide 88 by the smallest prime number possible. Then you take the result from that and divide that by the smallest prime number. Repeat this process until you end up with 1.

88 ÷ 2 = 44

44 ÷ 2 = 22

22 ÷ 2 = 11

11 ÷ 11 = 1

Again, all the prime numbers you used to divide above are the Prime Factors of 88.
