Step-by-step explanation:

v=[tex]\pi[/tex]r²h

84[tex]\pi[/tex]=

84[tex]\pi[/tex]÷7

12=r²

area of a circle is [tex]\pi[/tex]r²

so B is 12[tex]\pi[/tex]in²

The area of the base of the cylinder in the image given will be  12pi in.

The formula for the volume of a cylinder = πr²h, where:

Base area of the cylinder (B) = πr²

(r is the radius)

The Height of the cylinder = h

The given cylinder has the following,

Height of cylinder (h) = 7 in.

Volume of cylinder = 84pi in.³

Then Substitute into the volume formula:

(πr²)7 = 84pi

(B)7 = 84pi (B = area of the base)

Divide both sides by 7;

(πr²)7/7 = 84pi /7

B = 12pi

Therefore, the area of the base of the cylinder in the image given will be  12pi in.

Answer:

95%

Step-by-step explanation:

We convert 80 into ten or 100. In this case, we should use 10.

76/80 = 9.5/10

Then we set the denominator as 100. (because percentages have a denominator as 100)

95/100

Then it's 95%. Hope this helps.

Answer:

Density = 4779 grams per liter

Step-by-step explanation:

here we need to convert

pounds to gram

pint to liter

1 pound = 454 grams

1 pint = 0.57 liters

given

density = 6 pounds per pint

now using grams in place of pound and

liter in place of pint we have

density = 6 pounds per pint = 6*454 grams /0.57 liters

density = 2724 pounds/ 0.57 liters = 4778.94 grams / liters

Density when rounded to nearest whole number is 4779 grams / liters

Answer:

irrational

Step-by-step explanation:

Answer:

sqrt 169 is 13

sqrt 196 is 14

Step-by-step explanation:

The square root of the number in the fractional form [tex]\frac{169}{196}[/tex] is the number in fractional form [tex]\frac{13}{14}[/tex].

Given a number:

[tex]\frac{169}{196}[/tex]

It is required to find the square root of the number.

The square root of the fraction can be found by taking the square root of each component and dividing it.

That is:

[tex]\sqrt{\frac{x}{y} } =\frac{\sqrt{x} }{\sqrt{y} }[/tex]

Here, x = 169 and y = 196.

So, this can be written as:

[tex]\sqrt{\frac{169}{196} } =\frac{\sqrt{169} }{\sqrt{196} }[/tex]

         [tex]=\frac{13}{14}[/tex]

Hence, the fraction is [tex]\frac{13}{14}[/tex].

=======================================

The commutative property of addition is where we can add two numbers in any order we want. Example: 2+3 = 5 and 3+2 = 5.

In general, the rule is x+y = y+x.

In our case, 2x and 15 can be added in any order. So that's why 2x+15 is the same as 15+2x.

-------

Side note: a similar rule applies for multiplication as well. This is called the commutative property of multiplication. Example: 9*3 = 27 and 3*9 = 27. So we can say x*y = y*x.

Answer:

1. 2

2. -6

Step-by-step explanation:

I guess you tried to write -8-(-10) in the first question. Minus sign cancels out minus sign to give addition sign. So that is -8+10 which is 2.

The second question the sam thing applies -11-(-5) which is -11+5 which is -6

Answer:

The average change is 405

Step-by-step explanation:

The initially the number of subscriber = 12125

After five years the number of subscriber = 10100

Now we have to find the average change in the number of subscribers.

The average yearly change = change in subscriber/number of years.

Now insert the values in the above formula.

The average yearly change = (12125 – 10100) / 5

The average yearly change = 2025/5

The average yearly change = 405

Answer: The average change is -405

Answer:

[tex]7+(11-4\times 2)=10[/tex]

Step-by-step explanation:

So, this question involves you to play around with the numbers and the operations a bit. I've come up with a solution, but perhaps there are others as well.

So, we have:

[tex]7\text{ } 11\text{ } 4\text{ } 2\text{ } =\text{ } 10[/tex]

So, what we can do is, for instance, multiply 4 and 2. Subtract that into 11. And then add the difference to 7. Thus:

[tex]7+(11-4\times 2)=10[/tex]

This is a true number sentence. Let's do it to make sure.

First, do the operations inside the parentheses.

Multiplication comes first, so multiply:

[tex]7+(11-8)=10[/tex]

Again, do the parentheses first. Subtract:

[tex]7+(3)=10[/tex]

Now add:

[tex]10=10[/tex]

So our answer is correct :)

Answer:

When we have two vectors:

A = (a1, a2)

B = (b1, b2)

The distance between these two vectors is:

D = √( (a1 - b1)^2 + (a2 - b2)^2)

In this case, the vectors are:

U = (38, 22) and W = (55, 30)

The distance between U and W is:

D = √( (38 - 55)^2 + (22 - 30)^2 )

D = √( 289 + 64) = √353 = 18.7882

We want to round it to the nearest thousandths (the third digit to the right of the decimal point).

Then we must look at the next one (the fourth)

if the fourth digit is 5 or smaller, we round down

if the fourth digit is larger than 5, we round up.

We can see that in 18.7882 the fourth digit after the decimal point is a 2, so we round down, then the distance between U and W is:

D = 18.788

Now i guess that you want a line that connects U with W so the robot can follow it,

To find the line you can use a linear relation:

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

So we want a line that passes through the points U and W, the slope of this line will be:

a  = (30 - 22)/(55 - 38) = 0.47

Then the equation is:

y = 0.47*x + b

to find the value of b, we know that this line passes through the point (38,22) then:

y = 22 = 0.47*38 + b

b = 22 - 0.37*38 = 7.94

The line that can use the robot to go from U to W is:

y = 0.47*x + 7.94
