Answer:

51/12

as a mixed number

4 1/4

Step-by-step explanation:

first you add 8 to 4 which is 12

so the improper fraction would be 51/12

how to turn it in to a mixed number in simplest form

step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 51 by 12 and keep only what is to the left of the decimal point:

51 / 12 = 4.2500 = 4

Step 2 - Find New Numerator

Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.

51 - (12 x 4) = 3

Step 3 - Put Together

Keep the original denominator and use the answers from Step 1 and Step 2 to get this:

4  

  3  

  12  

Step 4 - Minimize

Minimize the fraction part from Step 3 by dividing the numerator and denominator by 3, which is the greatest common factor, to get the final answer. 51/12 as a Mixed Number is:

4  

  1  

  4

k =1.89 is the constant of  proportionality that represents the  relationship between the cost, y, to the  number of pounds of potatoes, x .

<u>Step-by-step explanation:</u>

Here we have , The cost of 2 pounds of potatoes is  $3.78. We need to find  the constant of  proportionality that represents the  relationship between the cost, y, to the  number of pounds of potatoes, x . Let's find out:

Cost is y &  number of pounds of potatoes is x  :

y = (k)x , where k is constant of  proportionality that represents the  relationship between the cost, y, to the  number of pounds of potatoes, x .

⇒ y = (k)x

⇒ 3.78 = (k)2

⇒ \frac{3.78}{2} = \frac{(k)2}{2}

⇒ \frac{3.78}{2} =k

⇒ k =1.89

Therefore, k =1.89 is the constant of  proportionality that represents the  relationship between the cost, y, to the  number of pounds of potatoes, x .

babunello [35]

Answer:

DBH is an obtuse angle.

Step-by-step explanation:

D is around the 15 degree mark. h is around the 144 degree mark. Subtract 15 by 15 and 144 by 15 degrees, so that way angle D would be on the 0. You would get 129 degrees, which still makes it obtuse because is greater than 90 degrees

algol13

Answer:

Step-by-step explanation:

the perimeter P=2(L+W)=54

P=2L+2W=54 OR L+W=27

we know that L=3W+3

P=3W+W=27-3

4W=24

W=6 CM

L=21CM

A rectangle has an area of 48 square units and a perimeter of 32 units. What are its dimensions?
baherus [9]
Area is length x width, and perimeter is adding up all the sides together
so if it’s 32 for the perimeter, then the dimensions should be 12 and 4
12x4 is 48
12+12+4+4 is 32
