Answer:

See below

Step-by-step explanation:

70/100 + 4/10 is equivalent to 70/100 + 40/100 which equals 110/100.

68/100 + 6/10 is equivalent to 68/100 + 60/100 which equals 128/100.

6/10 + 12/100 is equivalent to 60/100 + 12/100 which equals 72/100.

4/10 + 34/100 is equivalent to 40/100 + 34/100 which equals 74/100.

None of them equal 75/100, however if you were looking for 74/100 or 72/100, check above.

Gianna is making two different salads. One calls for 3 3/4 cups chopped spinach. The other calls for 2 2/3 cups chopped spinach.

ch4aika [34]

<h2> The answer is very simple add the whole numbers then find the LCM of 3 and 4 which is 12 then multiply 3/4 by 3 which will be 9/12 then multiply 2/3 by 4 which will be 9/12 then we add 9/12 + 8/12 which will equal to 5 17/12 which we can reduce and answer will be 6 5/12 spinach.</h2>

Solve the proportion<br>16/6 = 3s/9

iris [78.8K]

Answer:

Step-by-step explanation:

So you can start by simplifying each fraction:

16/6 divide by 2/2 = 8/3

3s/9 divided by 3/3 = s/3

Then, since 8/3 = s/3 you just have s = 8.

The length of a rectangle is five times it’s width if the area of the rectangle is 320m^2 find its perimeter

BlackZzzverrR [31]

Answer:

Perimeter of the rectangle = 96 meters.

Step-by-step explanation:

Let the width of the rectangle = K

So, the length of the rectangle = 5K

Area = 320 sq meters

Now, Area of a Rectangle = Length x Width

⇒ 320 = K x 5K

or, $5K^{2} = 320\\or, K^{2} = \frac{320}{5} = 64$

So, the vlue of K = 8 or, K = -8

But as K represents a length hence, K ≠ -8

So, the <u>width of the rectangle = 8 meters</u>

and the<u> length of the rectangle = 8 x 5 = 40 meters</u>

Now, Perimeter = 2(length + width)

= 2(8 + 40) = 96 meters.

So, the perimeter of the rectangle = 96 meters.
