Answers

Answer:

Step-by-step explanation:

x + 17 + 6x + 10 + 4x - 34 = 180

11x + 27 - 34 = 180

11x - 7 = 180

11x = 187

x = 17

x + 17 = 17 + 17 =34

6(17)+10 = 102 +  10 = 112

Large chocolate bar has a base area of 48.96 square feet and its length is 0.6 foot shorter than twice its width. Find the length and width 

Answers

Answer:

Length=9.6

Width=5.1

Step-by-step explanation:

Step one:

given data

for the large chocolate

Area=48.96ft^2

let the width be x

w=xft

let the length be l

l=(2x-0.6)

Step two:

we know that area A=length * width

48.96=(2x-0.6)*x

48.96=2x^2-0.6x

2x^2-0.6x-48.96=0

divide through by 2 we have

x^2-0.3x-24.48=0

solving the quadratic equation, the roots are

x=5.1

x=-4.8-----not correct cannot be -ve

so x=5.1

the width is 5.1

the length = 2(5.1)-0.6

l=10.2-0.6

l=9.6

check Area= 9.6*5.1= 48.96

The length and the width of the bar are 6.7ft and 7.3ft respectively

The formula for calculating the volume of the chocolate bar is expressed as:

V = Base area * height

Given the following parameters

Base area = 48.96 square feet B = length * width48.96 square feet = lw

If the length is 0.6 foot shorter than twice its width, hence;

l = w - 0.6

The expression becomes;

[tex]48.96 = w(w-0.6)\\48.96 = w^2 - 0.6w\\w^2 - 0.6w - 48.96 - 0[/tex]

On factorizing the result, w = 7.3ft

Recall that l = w - 0.6

l = 7.3 - 0.6

l = 6.7ft

Hence the length and the width of the bar are 6.7ft and 7.3ft respectively.

Thomas rented a bus so he and his friends could go to a concert. He had to pay a flat fee of $40 for the bus plus an additional $0.70 per mile. If he paid a total of $104.40, how many miles in total was the trip?

Answers

Answer:

so if Thomas payed $40 for the bus we have to find what he payed not including the $40 bus fee.

so we have to subtract 40 from the total price of $104.40.

the equation is 104.40-40=?

104.40-40=$64.40 payed outside the bus fee.

now we have to figure out how many times .70 fits into 64.40

the equation would be 64.40/.70 which means we are dividing 64.40 by .70

so 64.40/.70=92

Thomas and his friends traveled a total of 92 miles to go to the concert.

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the maximum height reached by the rocket, to the nearest tenth of a foot.
y=-16x^2+228x+71

Answers

Answer:

883.3

Step-by-step explanation:

thats all.

An equation is formed of two equal expressions. The maximum height reached by a rocket, to the nearest tenth of a foot is 883.3 feet.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

To find the maximum height through which the rocket will reach, we need to differentiate the given function, therefore, we can write,

y=-16x²+228x+71

dy/dx = -16(2x)+228

Substitute the value of dy/dx as 0, to get the value of x,

0 = -32x + 228

228 = 32x

x =7.125

Substitute the value of x in the equation to get the maximum height,

y=-16x²+228x+71

y=-16(7.125²)+228(7.125)+71

y=883.3feet

Hence, the maximum height reached by the rocket, to the nearest tenth of a foot is 883.3 feet.
