Mathematics
1 answer:
ddd [48]3 years ago
3 0

Answer:

96

Step-by-step explanation:

first off you know that it is a square pyramid, so you can assume that all base lengths are 6.

i am going to find the base first. it is 36 because 6*6-36 save this in your mental memory

next, we have to find the 4 triangles

we know that they are 5 by 6 but you have to divide them by 2

so 30/2=15 and there are 4 of them

15*4=60

now add together 60 and 36 and you get 96

hope this helps!

You invest $1000 in an account at 2.5% per year simple interest. How much will you have in the account after 3 years? Round to t
denis23 [38]
<span>Interest = Principle * rate * time
I = PRT

</span><span>P = 1000
R = 2.5% -- change to a decimal = .025
T = 3
</span>
<span> now we sub I = PRT
I = (1000)(.025)(3)
I = 75
 so at the end of 3 years, there will be : 1000 + 75 = $ 1075 in the account</span>
