Match The Following, Cylinder Rectangular Prism Cone Triangular Prism Square Prism

Answers

Answer 1
Surface Area of following shapes

Cylinder = 2πrh + 2πr²

where "h" - height, "r" - radius

Rectangular Prism = 2lw + 2lh + 2wh    also      2B + Ph

"l" - length, "w" - width, "h" - height

Cone = πrl + πr²

"l" - slant height, "r" - radius

Triangular Prism = 2B + Ph

"B" - area of one base, "P" - perimeter of base, "h" - height

Square Pyramid = 2l l + l²

"l " is height, "l" is side length

How much are bike uses a petrol and oil mixture in the ratio 17:3.
A) how much of each is there in 25 litres of mixture?

Answers

By using the given ratio, we will see that 21.25L is petrol and 3.75L of oil.

How much of each component is used?

We know that Petrol and Oil is used in a mix with a ratio of 17:3

Then, in 25 liters, then first we need to divide this by 20 (the sum of the two numbers of the ratio), we get:

25 L/20 = 1.25L

So we divided 25 liters in 20 parts. 17 of these parts are petrol, and 3 of these parts are oil

Then:

17*1.25L = 21.25L of petrol

3*1.25L = 3.75L of oil.

Find the slope of the line that is parallel and perpendicular to the following equation.
-5x - y = 1

Answers

Answer:

slope of perpendicular: [tex]\sf \bold{\frac{1}{5} }}[/tex]

slope of parallel: -5

rewrite in slope intercept form:                           [ y = mx + b ]

-5x - y = 1-y = 1 + 5xy = -5x - 1

comparing with y = mx + b       [ where m is slope, b is y-intercept ]

Parallel slope is same

formula: m₁ = m₂

m = -5

slope of parallel: -5

Perpendicular slope is negatively reciprocal

formula: m₁ = -(m₂)⁻¹

m₁ = -(-5)⁻¹m₁ = -(-1/5)m₁  = 1/5

slope of perpendicular: 1/5

Answer:

Slope of the line that is parallel: -5

Slope of the line that is perpendicular: [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

For the parallel line:

Rewrite your equation to slope-intercept form: y = mx + b

y = mx + b

m = slopeb = y-intercept (when x = 0)

-5x - y = 1 <== add 5x to both sides

+5x      +5x

-y = 5x + 1 <== divide both sides by -1

/-1      /-1

y = -5x - 1

The slope of the line that is parallel to this line is -5.

For the perpendicular line:

*Perpendicular lines have negative reciprocals*

Steps:

1. Take your original slope (-5)

2. Flip it (-1/5)

3. Change the sign (1/5)

For a slope of -5, the reciprocal would be: [tex]\frac{1}{5}[/tex]

d-22 > 28; d > 50
d +22 28; d > 72
d + 22 s 28; ds 72
d-22 28; d = 50

Answers

Answer:

Answer:

d--22→ 28

d→ 50

Step-by-step explanation:

Let d dollars be the initial amount in your bank account.

We have been given that you spent $22, so the amount left after spending $22 will be: .

We are also told that after spending $22, you have at least $28. This means that the amount left after spending $22 will be greater than or equal to $28.

We can represent this information in an equation as:

Therefore, the inequality represents the initial amount of money you had.

Now let us solve for d by adding 22 to both sides of our inequality.

Therefore, initially you had at least $50.

Dogs lap water to drink it. Every 3 minutes a dog laps water, it gets 30 ounces. If a dog needs 155 ounces per day, predict how many minutes the dog will lap water.

Answers

Answer:

15 minutes and 51 seconds

Step-by-step explanation:

155/30 = 5.17

5.17 x 3 = 15.51

It will take the dog approximately 15.5 minutes to lap enough water to consume 155 ounces.

Here, we have to predict how many minutes a dog will lap water to consume 155 ounces per day, we can set up a proportion based on the given information:

1 dog laps water every 3 minutes and gets 30 ounces.

Therefore, in 1 minute, a dog laps 30/3 = 10 ounces.

Now, we want to find out how many minutes it takes for the dog to consume 155 ounces:

Let x be the number of minutes the dog laps water to consume 155 ounces.

Proportion:

(Ounces lapped in x minutes) / (Ounces lapped in 1 minute) = (Total ounces needed) / (Ounces lapped in 1 minute)

(10x) / 10 = 155 / 1

Simplify the equation:

10x = 155

Now, solve for x:

x = 155 / 10

x = 15.5

So, it will take the dog approximately 15.5 minutes to lap enough water to consume 155 ounces.

Assume your friend just took an exam made up of 20 true/false questions. further assume that your friend had no knowledge relevant to the questions, and consequently just guessed the answer to each question what is the probability your friend will pass the exam?

Answers

Answer:

10/20 or 1/2 it is 50% chance that she pass and 50% that she fail

Step-by-step explanation:

The probability of your friend passing the exam by pure guessing is 0.176 or about 17.6%.

The probability of guessing correctly on any individual question is 0.5 (50%).

If the passing grade is, for example, getting at least 50% of the questions correct, your friend needs to get 10 or more questions correct.

The probability of guessing correctly on exactly k questions out of 20 is given by the binomial probability formula:

[tex]P(X = k) = C(n, k) * p^k * (1 - p)^{(n - k)[/tex]

For k = 10 (minimum number of correct answers to pass):

[tex]P(X = 10) = ^{20}C_{10} * (0.5)^{10} * (1 - 0.5)^{(20 - 10)[/tex]

P(X = 10) = 0.176197052

A store pays $75 for a phone. The customer pays $112.50 for the phone. What percent mark up was put on the phone?

Answers

Answer:

50% markup

Step-by-step explanation:

112.5-75=37.5

Since you know it is a $37.5 increase, you need to calculate how much of 75 is 37.5

37.5 is HALF of 75, so it was a 50% markup

Answer:

50% increase

Step-by-step explanation:

Firstly, I would do 112.50 - 75 = 37.5

This is an easy question, because we can quickly realise that half of 75 (75 divided by 2) is 37.5.

Because we know that 1/2 = 50% we can say that there was a 50% increase (or mark up) on the phone.
