Find the surface area of a cylinder with radius r = 6 and height h = 14.8 to the nearest tenth of a square cm. Use π = 3.14.
A).783.7 cm2
B).226.1 cm2
c).391.9 cm2
D).1,673 cm2

Answer:

A: 80 and B: 5.5

Step-by-step explanation:

For A, just multiply 20 and 4 and which you would get 80 miles. And for B, if 1 inch is equal to 20 miles, you can divide 110 and 20 but the answer will be 5.5 rather than 5.

I think this is right but if you can, try and see if it’s correct later.

Answer:

136 in

Step-by-step explanation:

Assuming the figure is a square with equal sides, then

4x - 2 = 3x + 7 ( subtract 3x from both sides )

x - 2 = 7 ( add 2 to both sides )

x = 9

Thus side = 3x + 7 = 3(9) + 7 = 27 + 7 = 34

Thus

perimeter = 4 × 34 = 136 in

Answer:

a. Let x be the number of chocolate-chip cookies for the forwards and y be the number of snicker doodles for the defenders. We have the following information:

- The total number of cookies needed is at least 100: x + y ≥ 100.

- The defenders eat more than four times as many cookies as the forwards: y > 4x.

To graph this system of inequalities, we can first graph the line y = 4x (dotted line) and shade the region above it, since y is greater than 4x. Then, we can shade the region above the line x + y = 100 (solid line), since the total number of cookies must be at least 100. The solution region is the shaded region that satisfies both inequalities.

b. Three possible combinations of cookies are:

- x = 10, y = 60. This corresponds to the point (10, 60) in the solution region.

- x = 20, y = 80. This corresponds to the point (20, 80) in the solution region.

- x = 30, y = 90. This corresponds to the point (30, 90) in the solution region.

c. Yes, Meghan and John need another inequality to limit the number of cookies they have to make. Currently, there are no upper bounds on the number of cookies they can make. One possible inequality to add is x + y ≤ 200, which limits the total number of cookies to 200 or less.

Answer:

\(927\)

Step-by-step explanation:

\(900 \times (1+0.6\%)^5\)

\(900 \times (1+0.6/100)^5\)

\(900 \times (1+0.006)^5\)

\(900 \times (1.006)^5\)

\(900\times \:1.03036\)

\(927.32594\)

Answer:

927

Step-by-step explanation:

Total Population = 900

Annual rate of increase = 0.6 % of 900

=> \(\frac{0.6}{100}* 900\)

=> 0.6 * 9

=> 5.4

Rate of increase in 5 years = 5 * 5.4

= 27

Population after five years = 900+27

=> 927

Answer:

To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:

Step 1: Distribute the negative sign on the left side of the equation:

-(x + 3) = 2(x - 3)

=> -x - 3 = 2(x - 3) (using the distributive property)

Step 2: Expand the right side of the equation:

-x - 3 = 2x - 6

Step 3: Add x to both sides of the equation to isolate the x term on one side:

-x + x - 3 = 2x + x - 6

=> -3 = 3x - 6

Step 4: Add 6 to both sides of the equation:

-3 + 6 = 3x - 6 + 6

=> 3 = 3x

Step 5: Divide both sides of the equation by 3 to solve for x:

3/3 = 3x/3

=> 1 = x

So, the correct value of x that makes the equation true is B. 1.

PLEASE MARK BRAILYISTT :D

Answer:

B, one

Step-by-step explanation:

In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

Answer: 3/52 (~5.77%)

What we know:

How to solve:

  We need to find the probability of drawing one of 3 diamond face cards, which gives us all of the information we need. Using division, we can create a 'x amount of diamond face cards/y amount of total cards' probability.

Probability of a diamond  face card

Where P is the probability of drawing that card, x is the number of diamond face cards, and y is the total amount of cards.

Set up equation                                                     P = x/y

Substitute                                                               P = (3)/(52)

Answer: 3/52 (~5.77%)

Because there are 3 diamond face cards in the deck, the chance of drawing one is {3 cards out of 52 total}, which is 3/52.

The chance of drawing ANY face card is {(3 per suit, 4 suits=) 12 cards out of 52 total} 12/52 (~23.08%),

The chance of drawing ANY diamond card is {1 suit out of 4 suits} 1/4 (25%)

Answer: y=x-20

Step-by-step explanation:

(90,70) will be x1,y2. (30,10) will be x1,y1. Put these values into the slope formula, which is y2-y1/x2-x1. 70-10/90-30. 60/60=1. The slope is 1. Now to find the slope-intercept equation, use point slope form which is y-y1=m(x-x1). y-10=1(x-30). Distribute the 1 to the terms in the parenthesis. y-10=x-30. Add 10 to both sides to eliminate 10. y-10+10=x-30+10. y=x-20.

Answer:

Option d. (also option e depending on which way you want to calculate it)

Step-by-step explanation:

First, I should point out that percentage basically means 'out of one hundred' so 25% means '25 out of one hundred.' The value of the percentage increase = 25% × 865. The new value = 865 + The value of the percentage increase.

______________________________________

More Simple Explanation:

Alright, so this might not be a super 'mathematical' trick or related to this question but it still works. Basically we just have to convert 25% into a decimal which I do by moving the decimal point 2 numbers to the left. (Since we cannot see the decimal point in the percentage we automatically know that it stays at the end of 25 a.k.a 25.0) So now our number becomes 0.25 (we got rid of the percentage symbol). Now we just multiply 865 by 0.25 to get our answer!

______________________________________

More Mathematical Process *Basically the value and random useless stuff to know lol because my math teacher showed me this and I thought I needed to add this*:

1) Calculate the new value of the number increased by percentage of its initial value

The new value =

865 + The value of the percentage increase =

865 + (25% × 865) =

865 + 25% × 865 =

(1 + 25%) × 865 =

(100% + 25%) × 865 =

125% × 865 =

125 ÷ 100 × 865 =

125 × 865 ÷ 100 =

108,125 ÷ 100 =

1,081.25

2) Calculate the actual change (the difference) between the new value and the initial one

The actual change =

The new value - 865 =

1,081.25 - 865 =

216.25

(For positive numbers, the actual change = The value of the percentage increase)

Answer:

The answers are \(\frac{2}{5}, \frac{1}{4}, \frac{1}{10}, \frac{5}{2}, \frac{5}{8}, \frac{4}{1}, \frac{8}{5},\) and \(\frac{10}{1}\).

Step-by-step explanation:

Proportions are fractions that can be made by using the given numbers, which in this case are 2, 5, 8, and 20. Let's pair each one with the other three and then simplify if possible.

First, let's begin with 2:

\(\frac{2}{5} = \frac{2}{5}\)

\(\frac{2}{8} = \frac{1}{4}\)

\(\frac{2}{20} = \frac{1}{10}\)

Then, let's do 5:

\(\frac{5}{2} = \frac{5}{2}\)

\(\frac{5}{8} = \frac{5}{8}\)

\(\frac{5}{20} = \frac{1}{4}\)

Note that we already have \(\frac{1}{4}\), so we do not need to include an additional one.

Now, let us do 8:

\(\frac{8}{2} = \frac{4}{1}\)

\(\frac{8}{5} = \frac{8}{5}\)

\(\frac{8}{20} = \frac{2}{5}\)

See how we already have \(\frac{2}{5}\), so we won't have to include that as well.

Finally, let's do 20:

\(\frac{20}{2} = \frac{10}{1}\)

\(\frac{20}{5} = \frac{4}{1}\)

\(\frac{20}{8} = \frac{5}{2}\)

Now see that we already have both \(\frac{4}{1}\) and \(\frac{5}{2}\), so we won't have to include both of them, as they are both extras.

Hence, the answers are \(\frac{2}{5}, \frac{1}{4}, \frac{1}{10}, \frac{5}{2}, \frac{5}{8}, \frac{4}{1}, \frac{8}{5},\) and \(\frac{10}{1}\).

Answer:

The experimental probability of rolling a 2 or a 3 is 2/9 or 0.222222 (go as long as you like :D)

Step-by-step explanation:

Total number of times cube roller = T = 360,

we have 96 ones, 31 twos, 49 threes, 76 fours, 45 fives, and 63 sixes

The probability of rolling a 2 is,

since we get 31 twos out of 360 rolls,

P(2) = 31/360

The probability of rolling a 3 is,

since we get 49 threes out of 360 rolls,

P(3) = 49/360

the experimental probability of rolling a 2 or a 3 is the sum of these two,

so,

P(2 or 3) = P(2) + P(3) = 31/360 + 49/360 = 80/360 = 2/9

P(2 or 3) = 2/9

In decimal form, P(2 or 3) = 0.2222222

The experimental probability of rolling a 2 or a 3 is 2/9 or (0.2222) .

The number of times a 2 or a 3 was rolled is the sum of the occurrences of twos and threes,

P(2) = 31

P(3) = 49

P(2) + P(3) = 31 + 49 = 80.

The total number of rolls is given as 360.

Now, calculate the experimental probability:

Experimental probability of rolling a 2 or a 3 = Number of times a 2 or a 3 was rolled / Total number of rolls

P(2 or 3) = 80 / 360

After simplifying the fraction:

Experimental probability of rolling a 2 or a 3 = 2/9

Therefore, the experimental probability of rolling a 2 or a 3 is 2/9.
