Split the composite figure in two
a rectangular prism and a isosceles triangular prism
when u have the figures separated use the formulas for the each
rectangular prism formula- A=2(wl+hl+hw)
isosceles triangular prism formula- a= 2b+ph
add both surface areas to get the answer
Cos = adj/hyp
hyp = AB
cos(25) = 7/AB
AB = 7.7
Answer: 15
Step-by-step explanation:
Since we are informed that in exchange for 5 eclaire boxes, that Luna gets, she decided to give 1 eclaire box for free.
Then, the number of eclaires boxes that they can buy from Luna using 77 claire boxes will be:
= 77 / 5
= 15 2/5
= 15 approximately
They'll get 15 boxes of eclaires from Luna.
Answer:
Step-by-step explanation:
let x = apples and y = bananas
x + y = 20
.5x + .75y = 11.5
solving for x
x = 20 - y
.5(20 - y) + .75y = 11.5
10 - .5y + .75y = 11.5
-.5y + .75y = 11.5 - 10
.25y = 1.5
y = 1.5 / .25
y=6
therefore x=14
14 apples and 6 bananas
The largest is going to be 14,000
