Answer:
2.45c + 1.65c = 4.12 + 0.75
Step-by-step explanation:
To write an equation to find the value for c, we need to declare what c is first.
c = price of fruit
2.45c + 1.65c = 4.12 + 0.75
Now we multiplied c to 2.45 and 1.65 and added them together, because whatever the value of c is will give us the equivalence of the sum of 4.12 + 0.75.
Now to check if the equation is right, let's solve for c.
2.45c + 1.65c = 4.12 + 0.75
4.1c = 4.87
Now to get the value of c, we divide both sides of the equation by 4.1.
![\dfrac{4.1c}{4.1}=\dfrac{4.87}{4.1}](https://tex.z-dn.net/?f=%5Cdfrac%7B4.1c%7D%7B4.1%7D%3D%5Cdfrac%7B4.87%7D%7B4.1%7D)
c = 1.19
Now let's substitute the value of c in the equation to see if we got it right.
2.45(1.19) + 1.65(1.19) = 4.12 + 0.75
2.92 + 1.96 = 4.87
4.87 = 4.87
Therefore concluding that the value of c is 1.19.

Answer:
The volume of the hemisphere is 1,475.73 cm³.
Step-by-step explanation:
Given that a hemisphere is half a sphere, to determine the volume of a hemisphere with a diameter of 8.9 cm, the following calculation must be performed, knowing that the volume of a sphere is equal to 4/3 πr³, and the radius is half the diameter:
8.9 x 2 = 17.8 / 2 = 8.9
(4/3 x 3.14 x 8.9³) / 2 = X
(1.333 x 3.14 x 704.969) / 2 = X
(4.18666 x 704.969) / 2 = X
2,951.47 / 2 = X
1,475.73 = X
Therefore, the volume of the hemisphere is 1,475.73 cm³.

Answer:
$4.00
Step-by-step explanation:
We assume the price is proportional to the quantity of oranges. If p is the desired price in dollars, we want ...
p/8 = 0.25/(1/2)
p = 8(0.50) = 4.00 . . . . multiply by 8, simplify
8 kg of oranges would cost $4.00.
