Answer:
6
Step-by-step explanation:
We can make:
A 3 sided shape and a 13 sided shape (3 + 13 = 16)
A 4 sided shape and a 12 sided shape (4 + 12 = 16)
A 5 sided shape and an 11 sided shape
A 6 sided shape and a 10 sided shape
A 7 sided shape and a 9 sided shape
2 8 sided shapes
Therefore the answer is 6.
Given :-
- Two cubes each of volume 27cm³ are joined to make a cuboid .
To Find :-
- The surface area of the resulting solid .
Solution :-
Given that the volume of cube is 27cm³ . We know that the volume of cube is given by (side)³ .
So , if we assume each side to be a , then ,
a³ = 27cm³
a = ³√{27cm³}
a = ³√3³cm³
a = 3 cm .
- Hence , if we join two cubes we will get a cuboid of length 3cm + 3cm = 6cm . (l)
- The breadth would be 3cm .( b)
- The height would be 3cm .(h)
See attachment for figure .
And as we know that TSA of cuboid is ,
TSA = 2( lb + bh + hl )
TSA = 2 ( 6*3 + 3*3 + 3*6) cm²
TSA = 2 ( 18 +9 +18 )cm²
TSA = 2 * 45cm²
TSA = 90 cm²
<u>Hence</u><u> the</u><u> </u><u>new </u><u>surface</u><u> area</u><u> of</u><u> the</u><u> </u><u>solid</u><u> </u><u>is </u><u>9</u><u>0</u><u>c</u><u>m</u><u>²</u><u> </u><u>.</u>

Answer:
2 cm (Answer B)
Step-by-step explanation:
This is a right triangle, and therefore the Pythagorean Theorem applies:
(shorter leg)² + (longer leg)² = (hypotenuse)²
In this case, (longer leg)² = (hypotenuse)² - (shorter leg)², or
(longer leg)² = (13 cm)² - (5 cm)², or:
(longer leg)² = 169 cm² - (25 cm²) = 144 cm²
The length of the longer leg is the square root of 144 cm², or 12 cm (Answer B)
Answer: y = 10x
This line goes through the two points (0,0) and (1,10)
(0,0) means x = 0 and y = 0 pair up. At time x = 0 seconds, aka the starting time, the height is y = 0 (the balloon is on the ground).
(1,10) means x = 1 and y = 10 pair up. At time x = 1 second, the balloon is y = 10 feet off the ground.
