The formula for the area of a rhombus with diagonals of lengths c and


d is A = 1/2= cd.


Solve the formula for c.


b. The area of a rhombus is 35 square feet. The length of one of the diagonals is 10 feet. What is the length of the other diagonal?


c. In a square (which is a rhombus), the lengths of the diagonals are the same. If a square has an area of 32 square feet, then what is the length of each diagonal?

Answers

Answer: part a.) c =2A/d

Part b.) d = 7

Part C The diagonals are each 8

Step-by-step explanation: part b:

35= 10d/2 70= 10d. 7 =d

Patty can make 10 purses in 8 hours. At this rate, how many purses can she make in 28 hours? ​

Answers

Answer:

35 purses

Step-by-step explanation:

Set up a proportion, where x is the number of purses she can make in 28 hours:

[tex]\frac{10}{8}[/tex] = [tex]\frac{x}{28}[/tex]

Cross multiply and solve for x:

8x = 280

x = 35

Answers

Answer:

c = 29

Step-by-step explanation:

Alright, So from the numbers, we know each side is 7

So overall area is 49

And each triangle is 5(5 x 2/2)

And multiply that by 4 to get 20

49 - 20 is 29

Answer:  the length of c is √29

Step-by-step explanation:

The Pythagorean Theorem states that "The square on the hypotenuse is equal to the sum of the squares on the opposite sides."

The formula looks like c² = a² + b²

To apply that here, "c" is the hypotenuse of the right triangle that has "2" and "5" as the opposite sides. We can consider 2 as side a, and 5 as side b.

Square each of those numbers, then add them together.

2² means 2×2=4  and 5² is 5×5=25   4+25 = 29

Now we go into reverse to get the value of c.  We have c²=29

So we take the square root of 29  c=√29

That is an "irrational" number, meaning it is not a whole number or a fraction. So we can get an approximate value by using a calculator. (Nowadays! Back in the day, there was a nice long paper and pencil procedure. . .)

√29 is about 5.385164807....  and it keeps going. Just round it off!

(Some math teachers are fine with leaving the irrational roots as √something)

Apparently, the green answer box for this question needs √29

But it helps if you can associate some nearly rational value to make sense of it.

But you know the length of c should be about 5.39. It makes sense if you were to measure the sides with a ruler.

A ribbon is 5 4/5 yards long. Mae needs to cut the ribbon into pieces that are 4/5 of a yard long. How many pieces of ribbon can she cut?

Answers

The answer is 7 pieces.

If you divide 5.80 (5 4/5) by 0.80 (4/5), you get 7.25. Since Mae probably doesn't want to use a piece of ribbon smaller than the others she will only cut 7 pieces.  

Answer:

7

Step-by-step explanation

5 4/5 = 5/5, 5/5, 5/5, 5/5, 5/5, 4/5

so five 5/5 - 1/5 each = 4/5, 4/5, 4/5, 4/5, 4/5 so we now have five 4/5 + the 4/5 we had at the beginning so we have six 4/5 then add all of the 1/5 we took away from all of the 5/5 so 1/5 x 5 = 5/5 = 4/5 Remainder 1/5 so we now have seven 4/5 and an extra 1/5

so, in conclusion, Mae can cut seven pieces of ribbon.
