Select the correct answer. The number of oranges purchased varies directly as the price of the oranges. If 11 oranges cost $2.35

Vlad1618 [11]

Answer:

A. 3.85

Step-by-step explanation:

If 11 oranges cost $2.35, we could calculate the cost of each of these oranges, simply dividing the total cost ($2.35) between the amount of oranges bougth (11). This will give us the cost of a single orange, that is, the unitary cost= $\frac{2.35}{11}= 0.21$ .
Then, if we want to know the cost of 18 oranges, we just have to multiply the cost of a single orange (0.21) by 18: 0.21x18 = 2.85

HELP PLSSSSSSSS!!! TY!!! If the sum of four consecutive numbers is 1998, what is the third number? The third number is ?

tensa zangetsu [6.8K]

Answer:

500

Step-by-step explanation:

Hello!

Let the smallest number be x. The next number would be x + 1, then the next would be x + 2, then x + 3.

The sum of these four is 1998.

Solve for x:

x + (x + 1) + (x + 2) + (x + 3) = 1998
4x + 6 = 1998
4x = 1992
x = 498

The third number is (x + 2), so simply add 2 to 498 = 500

The third number is 500.

All 4 numbers are 498, 499, 500, and 501.

The differential equation below models the temperature of a 95°C cup of coffee in a 19°C room, where it is known that the coffee

frozen [14]

Answer:

y (t) = 19 + 76*e^(-(1/51)*t)

Step-by-step explanation:

We have the following differential equation model:

dy / dt = - (1/51) * (y -19)

The initial conditions are: y (0) = 95 and y '(70) = 1

We solve the differential equation, separating variables:

1 / (and -19) * dy = - (1/51) * dt

we integrate on both sides:

ln (y -19) = - (1/51) * t + C

e ^ ln (y -19) = e ^ (- (1/51) * t + C)

y - 19 = C1 * e ^ (- (1/51) * t)

y = 19 + C1 * e ^ (- (1/51) * t)

replacing, and (0) = 95

95 = 19 + C1 * e ^ (- (1/51) * 0)

95 = 19 + C1 * e ^ 0

95 = 19 + C1

C1 = 95 - 19 = 76

Therefore the equation would be:

y (t) = 19 + 76 * e ^ (- (1/51) * t)
