The machine can make soda bottles each

arsen [322]

Answer:

The number of soda battles the machine can make per minute is 40

Step-by-step explanation:

What we simply want to do here is to use the two marked points to get the number of soda bottles made per minute

Mathematically, what we have to do here is to

use the two point slope equation

we have this as;

m = (y2-y1)/(x2-x1)

(x1,y1) = (3,120

(x2,y2) = (5,200)

m = (200-120)/(5-3) = 80/2 = 40

The end of a house has the shape of a square surmounted by an equilateral triangle. If the length of the base is measured to be

sergij07 [2.7K]

Answer:

The area of the end is 1755.44 ft²

Therefore, the maximum error in calculating area of the end is 8.3592

Step-by-step explanation:

Consider the provided information.

The length of the base is measured to be 35 feet, with a maximum error in measurement of 1 inch,

$1\ inch = \frac{1}{12}\ feet$

The area of shape = Area of square + Area of equilateral triangle

$A=x^2+\frac{\sqrt{3}}{4}x^2$

Substitute x=35 in above.

$A=(35)^2+\frac{\sqrt{3}}{2}\times (35)^2=1755.44$

Hence, the area of the end is 1755.44 ft²

Differentiate $A=x^2(1+\frac{\sqrt{3}}{4})$ with respect to x as shown:

$dA=2x\ dx(1+\frac{\sqrt{3}}{4})$

Substitute dx =1/12 and x=35

$dA=2(35)\ \frac{1}{12}(1+\frac{\sqrt{3}}{4})=8.3592$

Therefore, the maximum error in calculating area of the end is 8.3592

Answer:

The formula to find the volume of a cylinder is V = πr2h

The diameter divided by 2 is the radius. 5.5 divided by 2 is 2.75

v = π2.752 16.5

V = 391.8

The answer is 391.8

I hope this helps please mark me Brainliest! Have a nice day!
