In both of the problems, x equals 0 and y equals 1
Step-by-step explanation:
4+9+8+6+5+44+88+90+78= 332
Volume=length times width times height
this should be easy
a.
the volume of a box is 2.5 times 1 times 1 or 2.5 cubic meters
b.
number of boxes times volume per box=volume of container
number of boxes=volumecontainer/volumebox
find volumecontianer
volumecontainer=5 times 2 times 3=30 cubic meters
number of boxes=30/2.5
number of boxes=12
12 boxes needed to fill container
c.
box
1m=100cm
1m by 1m by 2.5m convert so (times everybody by 100)
100cm by 100cm by 250cm
multiply
2,500,000 cubic centimeters
Answer:
Step-by-step explanation:
<u>Heron's Area formula:</u>
- A =
, where s is semi-perimeter - s = 1/2(a + b + c)
We are given two sides and the included angle.
<u>Use the law of cosines to find the missing side:</u>
- a² = b² + c² - 2bccos A
- a² = 77² + 41² - 2*77*41*cos 79
- a² = 6405
- a = 80 (rounded)
<u>Now find the value of s:</u>
- s = 1/2(80 + 77 + 41) = 99
<u>Find the area:</u>
- A =
= 
= 1549.24
Answer:
8000
Step-by-step explanation:
Because when you will add it (8000+800+80+9)
then you will get 8889
