8 0

Answer:

The surface area is 302 in²

Step-by-step explanation:

Known :

Long (l) = 11 in

Weight (w) = 6 in

Height (h) = 5 in

Asked :

Surface Area (Sa) = ...?

Answer :

Formula :

= 2(l.w) + 2(l.h) + 2(w.h)

= \boxed{2 (l.w + l.h + w.h)}

= 2 (11×6 + 11×5 + 6×5)

= 2 (66 + 55 + 30)

= 2 × 151

= <u>3</u><u>0</u><u>2</u><u> </u><u>in²</u>

So, the surface area is 302 in²

A friends is buying flowers for mother's day. Because it is her 38th birthday, your friend want to have 38 of her favorite flowe
777dan777 [17]

Answer: She bought 28 daises and 10 Tulips.

Step-by-step explanation:

Let x represent the number of daises bought.

Let y represent the number of tulips bought.

Your friend want to have 38 of her favorite flowers. This means that

x + y = 38

Her favorite flowers are daisies at 1.50 each and tulips at 2.50 each if the total bill was 67, it means that

1.5x + 2.5y = 67 - - - - - - - - - - - - 1

Substituting x = 38 - y into equation 1, it becomes

1.5(38 - y) + 2.5y = 67

57 - 1.5y + 2.5y = 67

- 1.5y + 2.5y = 67 - 57

y = 10

x = 38 - y = 38 - 10

x = 28
