Answer:
28
Step-by-step explanation:
Let x be the missing segment
We will use the proportionality property to find x
24/16 = 42/x
Simplify 24/16
24/16= (4×6)/(4×4)= 4/6 = 3/2
So 3/2 = 42/x
3x = 42×2
3x = 84
x = 84/3
x= 28

Answer:
He can feed 200 plants
Step-by-step explanation:
To solve this, we will follow the step below:
first, convert 25 g to kg
25 g = 25/1000 = 0.025 kg
Now using proportion to solve;
Let x be the number of food plant he can feed the plant
0.025 kg = 1
5 kg = x
cross-multiply
0.025×x = 5×1
0.025x =5
Divide both-side of the equation by 0.025
0.025x/0.025 = 5/0.025
x=200 plants
Therefore, he can feed 200 plants
Answer:
228cm^2
Step-by-step explanation:
Multiply 18cm by 10cm:
18 x 10 = 180cm^2
So we have the area of the biggest/top part: 180cm^2
For the bottom part:
You've said the length of the bottom side is 8cm.
We know the length of the biggest side: 24cm. And we know the length of the opposite side: 18cm. So, to find the length of the missing side, it's simple subtraction:
24cm - 18cm = 6cm
So now we have lengths for 2 sides: 8cm and 6cm.
Multiply these to give the area:
8cm * 6cm = 48cm^2
Add these areas of both shapes together to give total area:
180cm^2 + 48cm^2 = 228cm^2
