Answer:

a = 62

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees

a + 47+71 = 180

Combine like terms

a +118 = 180

Subtract 118 from each side

a+118-118=180-118

a =62

Answer:

Step-by-step explanation:

The mode in statistics is the number that occurs the most in a data set.

So you basically have to find the set that has the most threes.

A and C both have 3 threes. I think there might be another 3 in one of those if there has to be only one answer.

So the answer can be either A or C.

Hope this helps!

If i u have 110 dogs and the ratio of puppies is 2:3. How many puppies

navik [9.2K]

Question: You have 110 dogs (which is the total amount of dogs/pups) and the ratio of the puppies is 2:3. How many puppies are there?

Add 2 and 3 which adds to 5 (You need to combine all the "pie pieces")

Now, divide 110 by 5

$110$ ÷ $5=22$

Now multiply 2 and 22

$2*22=44$

Now multiply 3 and 22

$3*22=66$

The ratio is 44:66

Answer: There are 44 puppies

Please help the answer are 12 4 X X+4 -16 16 X+12 X^2

Lorico [155]

Step 1:
x² + 4x = 192

Step 2:
Take x common:
x ( x + 4) = 192

Length is x and width is x+4

Step 3:

x² + 4x - 192 = 0

Step 4:

x² + 16x - 12x - 192 = 0
x(x+16) - 12(x+16) = 0
(x-12)(x+16) = 0

⇒ x=12, x=-16

Because the length can't be -16, the length is 12.
