Fill in the blank so that the ratios are equivalent. 3:9 and 6:

Answers

Answer: 18

Step-by-step explanation: The ratio 3:9 is equivalent to 1:3. This means that whatever number on the left side of the ratio should be multiplied by 3 to get the one on the right. 6 x 3 = 18.

The value of the unknown number for the fraction is equal to 18.

What are ratios and proportions?

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Given that the ratio is 3:9 then the value of the unknown number will be calculated as,

The ratio 3:9 is equivalent to 1:3. This means that whatever number is on the left side of the ratio should be multiplied by 3 to get the one on the right.

The unknown number will be,

6 x 3 = 18.

Therefore, the value of the unknown number for the fraction is equal to 18.

Mia is factoring the polynomial x2 + 4x – 12. She uses the steps shown.

A 2-column table with 4 rows. The first column has no label with entries Step 1, Step 2, Step 3, Step 4. The second column is labeled x squared + 4 x minus 12 with entries x squared + 6 x minus 2 x minus 12, (x squared + 6 x ) minus (2 x + 12), x(x + 6) minus 2(x + 6), (x + 6)(x + 2).

In which step did Mia make an error?
Step 1
Step 2
Step 3
Step 4

Answers

Mia's error is in step 4

What is factorization?

Factorization involves splitting a function into several factors

The steps in factorizing the expressions are:

Step 1: x^2 + 6x - 2x -12

Step 2: (x^2 + 6x) - (2x + 12)

Step 3: x(x + 6) - 2(x + 6)

Step 4: (x + 6)(x + 2)

From the step 3 to step 4, the resulting expression should be

(x + 6)(x - 2)

However, the step 4 of the expression is (x + 6)(x + 2)

The expected expression and the actual expression in step 4 are different.

Hence, Mia's error is in step 4

Answer:

a = 4.5

b = 5

Step-by-step explanation:

Answer:

b=7

area=20

a=5.66

perimeter=19.66

Step-by-step explanation:

Don't know your exact question but here goes everything:

since angle between a and b=45 degrees, b=4+3

b=7

area=(7x4)-1/2(4)(4)

area=28-8

area=20

a^2=4^2+4^2

a^2=16+16

a^2=32

a=5.66

What’s the value of a?

Answers

Answer:

a = 69

Step-by-step explanation:

The linear pair equals 180 degrees.

a + 90 + 21 = 180

a + 111 = 180

a = 69

nice!

Answer:

A= 69 degrees

Step-by-step explanation:

if all those angles equal a total of 180 degrees then all you need to do is add the angles your given which in this case is 21 and a 90 degree angle which would equal 111 degrees, then subtract 111 from 180 and that would be the answer to the missing angle, which is 69 degrees.

21 + 90 = 111

180- 111 = 69
