Answer:

surface area: 62.5π

explanation:

total surface area of cylinder: 2πr(h+r)

Given:

Solve:

2π(2.5)(10+2.5)

5π(12.5)

62.5π

Solution:

Given:

Surface area of cylinder: 2πrh + 2πr²

Using the formula:

[tex]2\pi rh + 2\pi r^{2} = \text{Surface area of cylinder}[/tex]

[tex]\rightarrow 2(3.14)(2.5)(10) + 2(3.14)(2.5)^{2} = \text{Surface area of cylinder}[/tex]

Simplifying the LHS:

[tex]\rightarrow (3.14)(50) + 2(3.14)(6.25) = \text{Surface area of cylinder}[/tex]

[tex]\rightarrow (31.4)(5) + (6.28)(6.25) = \text{Surface area of cylinder}[/tex]

[tex]\rightarrow \boxed{\bold{196.25 \ in^{2} = \text{Surface area of cylinder}}}[/tex]

Answer:

Simplifying the expression, the answer would be [tex]81u^1^2v^8[/tex].

Process:

Basically, you just need to multiply the power on the outside with the powers on the inside of the parenthesis. Then, for the base take -3 to the fourth power which will lead you to your final answer [tex]81u^1^2v^8[/tex].

Answer:

1 inch per 2 hours (it may be 0.5/hour)

Step-by-step explanation:

The graph shows there is 1 inch of snow after 2 hours of snowfall, and 2 inches after 4 hours, so the unit rate is 1 inch per 2 hours or 0.5/hour

Answer:

n=36

Step-by-step explanation:

36 divided by 2 is 16 then subtract 10 and you will get 6 hope this helps

Answer:

[tex]n = 32[/tex]

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and equals:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

~

First, add 10 to both sides of the equation:

[tex]\frac{n}{2} - 10 = 6\\\ \\\frac{n}{2}- 10 (+10) = 6 (+10)\\ \\\frac{n}{2} = 6 + 10\\\\\frac{n}{2} = 16[/tex]

Next, isolate the variable n by multiply 2 to both sides of the equation:

[tex]\frac{n}{2} = 16[/tex]

[tex]\frac{n}{2} *2 = 16 * 2[/tex]

[tex]n = 16 * 2\\n = 32[/tex]

[tex]n = 32[/tex] is your answer.

Answer:

4 and 280

Step-by-step explanation:

Answer: y = 16x   or  C = 16×f  

The number of cookies is 16 for each cup of flour used

Step-by-step explanation:

You can take numbers from the graph. For example, Number of Cookies: 192 and the Cups of flour: 12.  Divide the number of cookies by the amount of flour

192÷12 = 16

Check other numbers to be sure  96÷6 = 16

288÷18 = 16

You could fill in the chart by multiplying Cups of Flour by 16 to find the number of Cookies

C = 16 × f

C = 16 × 3

C = 48

Answer:

a 126 divided by 9=14 buttons

b 126 divided by 14=9 buttons

c 230/2=115 so 115 grams of each

115/9=12.7777777778

115/9=8.21428571429

so umm i guess round

13 of a

8 of b

Answer:

2.1 kilometers/1 day.

Step-by-step explanation:

9 kilometers ÷ 30/7 days, which is the same as (9 x 7)/30 which is = 63/30 = 2.1 kilometers/1 day.

Answer:

2.1 km a day

Step-by-step explanation:

9 km ÷ 30/7 days, in other words (9 x 7)/30 which equals 63/30 which is 2.1 kilometers/1 day.

Add the constants:

Add the angles:

Subtract 260 both sides:

Divide 2 both sides:

We know that:

This means that:

Answer:

40 miles

Step-by-step explanation:

First, change the 15 minutes to 0.25 hours and 3 minutes to 0.05 because we are working with mph.

let x be the normal driving time to work in hours so 40x is the driving to work

since we know distance = speed multiplied by time we do

50(x-0.25+0.05)=40x

50(x-0.2)=40x

50x-10=40x

50x-40x=10

10x=10

x=1 hour normal time to work

therefore

40(1) = 40 mi to work

Confirm this by finding the dist when he went 50 mph for 48 min (0.8hrs)

50(1-.25+0.05) = 50(.8) = 40 mi also

The diagram is shown below what happens when you dilate with a scale factor 2/3, and the center of dilation is D.

Line A'B' has the same slope of AB, so the lines are parallel.

Line AD and line A'D' are the same line, since D = D'. Recall that the center of dilation does not move when applying a dilation. Point A moves to A', which is one line AD. Due to D being at the center, all lines from the center will connect the four points shown.

Answer:

any point where x=3, 4, or 6.

Step-by-step explanation:

The thing that makes a function a function and not a relation is having only 1 y value per x value, which means if you draw a vertical line through a point, it should not intercept any other points. Basically, the main difference between a function and a relation is that a function can't have 2 points on top of each other.

Pick a point where x=3, 4, or 6. Those are the open spots on the grid with nothing above or below them. It doesn't matter which point you pick, as long as there is NOTHING directly above or below that point.

I hope you understood this solution. Happy mathing!
