An ice cream factory makes 100 quarts of ice cream in 5 hours how many quarts could be made in 36 hours
I am Lyosha [343]

Answer:

720 Quarts

Step-by-step explanation:

\frac{100}{5} = \frac{x}{36}

cross multiply

\frac{100}{5}*\frac{36}{36} = \frac{x}{36}*\frac{5}{5}\\\\\frac{3,600}{180}=\frac{5x}{180}

now that they are both divided by 180, we can eliminate it

3,600=5x\\\\\frac{3,600}{5}=\frac{5x}{5}\\\\720=x

A person of height 1.6m up to the eye level is standing at a point 2m away from the bank of the river and found an angle of elev
natima [27]

Step-by-step explanation:

tan30° = Height of person / (Distance away from river bank + river's width) = 1/√3.

Therefore 1.6m / (2m + x) = 1/√3

By cross multiplication, 1.6√3 = 2 + x.

Hence, x ≈ 0.77m.

Let me give you an example
6x + 5x + 14 + 6
So all you is combine 6x and 5x
11x +14 + 6
Then you just combine the other two numbers

Lera25 [3.4K]

Given:

The price of bananas can be determined by the equation P=0.25n, where P is the price and n is the number of bananas.

To find:

The constant of proportionality

Solution:

We have,

P=0.25n       ...(i)

where P is the price and n is the number of bananas.

Price P is directly proportional to the number of bananas. So,

P\propto n

P=kn            ...(ii)

Where, k is the constant of proportionality.

On comparing (i) and (ii), we get

k=0.25

Therefore, the constant of proportionality is 0.25.

two-point charges are 10.0 cm apart and have charges of 2.0 uc and -2.0uc respectively What is the magnitude of the electrical f
maks197457 [2]

Answer:

The electric field generated by a point charge is given by:

where

is the Coulomb's constant

Q is the charge

r is the distance from the charge

We want to know the net electric field at the midpoint between the two charges, so at a distance of r=5.0 cm=0.05 m from each of them. 

Let's calculate first the electric field generated by the positive charge at that point:

where the positive sign means its direction is away from the charge.

while the electric field generated by the negative charge is:

where the negative sign means its direction is toward the charge.

If we assume that the positive charge is on the left and the negative charge is on the right, we see that E1 is directed to the right, and E2 is directed to the right as well. This means that the net electric field at the midpoint between the two charges is just the sum of the two fields:
