Step-by-step explanation:

To solve this problem you must apply the formula for calculate  the surface area of the rectangular prism:

SA=2(wh+lw+lh)

Where w is the width, h is the heigh and l is the lenght.

Based on the rectangular prism shown, you have that:

w=9.08cm\\h=3.23cm\\l=11.73cm

Finally when you substitute values into the formula you obtain the following result:

SA=2[(9.08cm*3.23cm)+(11.73cm*9.08cm)+(11.73cm*3.23cm)]=347.45cm^2

Corey's salsa recipe calls for 2 1/2 cups of onions for every 4 pounds of tomatoes Corey Perseus 10 pounds of tomatoes and wonde
MissTica

Answer:

For 10 pounds of tomatoes 6.25 i.e. 6\frac{1}{4} cups of onions required.

Step-by-step explanation:

Corey's salsa recipe calls for 2\frac{1}{2} cups of onions for every 4 pounds of tomatoes.

If the amount of onions is represented by y in cups and the amount of tomatoes by x in pounds, then the proportional relation between x and y is

y = kx ............. (1)

{Where, amount of tomatoes is the independent variable and amount of onions is the dependent variable}

Now, putting x = 4 pounds and y = 2\frac{1}{2} i.e. 2.5 cups, we get from equation (1) as

2.5 = 4k

⇒ k = 0.625

Now, the equation becomes, y = 0.625x ........ (2)

Now, from equation (2) for, x = 10 pounds, y = 0.625 × 10 = 6.25 cups.

Therefore, for 10 pounds of tomatoes 6.25 i.e. 6\frac{1}{4} cups of onions required. (Answer)
