Details: Cargo ship can carry 21,600 tons Cars weigh 3.6 tons each Trucks weigh 7.5 tons each y = number of cars x= number of trucks Your equation was 3.6y + 7.5x = 21600 Find the number of trucks that can be shipped if there are no cars.​

Answers

Given:

The equation is

[tex]3.6y+7.5x=21600[/tex]

where, y is the number of cars and x is the number of trucks shipped.

To find:

The number of trucks that can be shipped if there are no cars.​

Solution:

We have,

[tex]3.6y+7.5x=21600[/tex]

If there are no cars in the cargo ship, then y = 0 because y is the number of cars.

Putting y=0 in the given equation, we get

[tex]3.6(0)+7.5x=21600[/tex]

[tex]0+7.5x=21600[/tex]

[tex]7.5x=21600[/tex]

Divide both sides by 7.5.

[tex]x=\dfrac{21600}{7.5}[/tex]

[tex]x=2880[/tex]

x is the number of trucks shipped.

Therefore, the number of trucks that can be shipped if there are no cars is 2880.

Carin has 2/3 of a bottle of paint. She uses 1/6 of a bottle to paint one model airplane. How many model airplanes can carin paint with 2/3 of a bottle of paint. Answer

h(t)=- 16t^2 +16t+12 zeros of the parabola

Answers

Step-by-step explanation:

h(t) = -16t² + 16t + 12

h(t) = -4(4t² - 4t - 3)

h(t) = -4(2t - 3)(2t + 1)

When h(t) = 0, we have t = 1.5 or t = -0.5.

Hence the zeroes are 1.5 and -0.5.

A new car is purchased for $32,500. The car depreciates every year ata
rate of 14%. Write an exponential function that represents that situation

Answers

Answer:

[tex]y=32500(0.86)^{x}[/tex]

Step-by-step explanation:

General exponentially depreciating function is given as

[tex]y= a(1-b)^{x}[/tex]------------(1)

Where a is initial value, b is percent depreciation/unit time  and x is time

Here

[tex]a=32,500 \ \ \ b=0.14 \ \ \ and \ \ x \ is \ time \ in \ years[/tex]

Substituting above values in equation (1)

[tex]y=32500(0.86)^{x}[/tex]

[tex]y=32500(0.86)^{0}\\y=32500[/tex]

At x=1

Explanation:

[1] - A

y = 90 (90 degree angle)

90 - 43 = 47, so x = 47

[2] - C

x = 92 because 180 - 88 = 92

x = 92 and y = 88 because 92 + 88 = 180

[3] - C

x = 28 because 90 - 62 = 28

[4] - D

x = 90 because 180 - 90 = 90

y = 85 because 42 + 53 = 95, 180 - 95 = 85

[5] - A

x = 133 because 180 - 47 = 133

Landing on 6 = 17

The experimental probability of landing in a two:

Experimental probability :

Number of times event occurs / Number of trials
