Answer:
1070cm2
Step-by-step explanation:
the cereal box represents a cuboid and it is closed hence a closed cuboid.
SA- Surface area
L- Length = 15
W- Width =4
H- Height =25
In a closed cuboid, there are going to be 6 faces( 3 pairs).
To find SA, we have to take the area of all faces and sum them up.
You can do this by carrying out the area of all faces and summing them up or you can use the formula:
SA of a closed cuboid=2(L x W) + 2(W x H) + 2(L x H)
= 2(15 x 4) + 2(4 x 25) + 2(15 x 25)
= 2(60) + 2(100) + 2(375)
=120 + 200 + 750
=<u>1070cm2</u>
It would be: 32/48 = 16/24 = 8/12 = 4/6 = 2/3
[ Just try to divide numerator & denominator by 2, until they reach at the position, when they can't reduce anymore ]
In short, Your Answer would be 2/3
Hope this helps!
Answer:2
Step-by-step explanation: first you multiply 10 x 20 than divided by 100
9x+3y=33
9x+3(-3x+11)=33
9x-9x+33=33
33=33
0=0

Answer:
In 7th month.
Step-by-step explanation:
Let the number of months = x.
It is given that Lucia bought 11 hectares of land in the 1st month and added 5 hectares each month after.
Amount of land Lucia bought, 
Now, Maria bought 6 hectares of land in the 1st month and increases land by a factor of 1.4 each month after.
Amount of land Maria bought, 
<em>So, we will form the table for the values of the functions representing the lands,</em>
Months (x) Lucia, Maria, 
1 11 6
2 16 8.4
3 21 11.8
4 26 16.5
5 31 23
6 36 32.2
7 41 45.1
8 46 63.1
So, we see that,
In 7th month, Maria'a amount of land will exceed Lucia's amount of land.
