He is 35 years old, because if you add 22 and 13 you get 35 which is her uncle's age.

A drink is mixed in the ratio

Contact [7]

Answer:

Step-by-step explanation:

Drink mix ratio:

Lemonade : Orange : Cranberry

6 : 3 : C

Fraction of Cranberry juice = $\frac{3}{12}$

Sum of the ratio = 6 + 3 + C = 9 + C

Fraction of Cranberry;

$\frac{C}{9 + C}$ = $\frac{3}{12}$

3(9 + C) = 12C

27 + 3C = 12C

27 = 12C - 3C

9C = 27

C = 3

The missing number will be 3

(3+11i)/(3+11i)=1

So that means you can multiply 6/(3+11i) by (3+11i)/(3+11i)

Then 6(3+11i)/1

= 18+66i

What is the factorization of the expression below?

olchik [2.2K]

Answer: D. (x-6)(x-6)

Step-by-step explanation:

We have the following trinomial, which is also known as perfect square trinomial, because the first and the third term are squares:

$x^{2}-12x+36$ (1)

First term: $x^{2}$

Third term: $36=6^{2}$

If we factorize this expression we have:

$(x-6)(x-6)=x^{2}-6x-6x+36=x^{2}-12x+36$

As we can see, the trinomial (1) has two factors:

$(x-6)$ and $(x-6)$

Therefore, the correct option is D.

What is the answer?

emmainna [20.7K]

Answer:

C. 2.75P

Step-by-step explanation:

The original value was P.

It increased by 275%. That means it increased by 275% of P.

275% of P = 2.75P

The increase in value is 2.75P.

Now we add the increase to the original value of P to find today's value.

2.75P + P = 3.75P

Answer: C. 2.75P
