Calculate the surface area of an open cylinder measuring 35cm in diameter and 60cm high.

Answers

Answer 1

Answer:

6598.2 in^2

Step-by-step explanation:

Given data

Diameter= 35in

Radius= d/2= 35/2= 17.5in

Height = 60cm

The expression for the curve surface area of a cylinder is

CSA=2πrh

substitute

CSA= 2*3.142*17.5*60

CSA= 6598.2 in^2

Hence the CSA is 6598.2 in^2

A student needs 15 minutes to solve an algebra problem. How many minutes does the student need to solve 5 problems?

it's easy, you only need to divide 15 by 5.

Like this :

15÷5= 3

because 5×3 = 15 , so you just need to flip it over

Homemade applesauce is one of Duncan's favorite foods, so he bought 10 pounds of apples at the farmers' market. His applesauce recipe says that 8 ounces of apples make 1 cup of applesauce. How many cups of applesauce can he make with 10 pounds of apples?

Answers

Answer:

20 cups of applesauce

Step-by-step explanation:

8 ounces = 0.5 pounds

Pounds of apples : cups of applesauce

0.5 pounds : 1 cup = 10 pounds : x cups

0.5/1 = 10/x

0.5*x = 1*10

0.5x = 10

x = 10/0.5

x = 20 cups of applesauce

10 pounds of apples will make 20 cups of applesauce

Which box plot correctly summarizes the data?

Answers

The right box plot that summarizes the data should look like the one constructed below in the diagram attached.

We are given the data set 25, 28, 29, 29, 30, 34, 35, 35, 37, and 38, which are already in order and we need to derive the min, max, median, Q1, and Q3 from the given data set. We need all of these values to construct a box plot to summarize the data.

Now, we will find the minimum value which is 25. The maximum value in the data set is 38. The median is the middle value of the data set and it will lie between the 5th and the 6th data points. The average of both values would give us our median data point = (30 + 34) ÷ 2 = 32

Our Q1 would be the middle data point of the bottom half of the data set which is 29. Q3 would be the middle data point of the top half of the data set = 35. As we have derived these values, we can now construct a box plot to summarize the given data.

Therefore, the right box plot that summarizes the data should look like the one constructed below in the diagram attached.

The vertex angle of an isosceles triangle is three times the measure of either base angle. Find the area if the measure of the congruent sides are 14 in

Answers

Answer:

[tex]Area = 93.21in^2[/tex]

Step-by-step explanation:

Given

[tex]\theta \to[/tex] vertex angle

[tex]\alpha \to[/tex] base angle

[tex]\theta = 3\alpha[/tex]

[tex]l = 14in[/tex] -- congruent sides

Required

The area of the triangle

First, calculate the angles

[tex]\theta + \alpha + \alpha = 180^o[/tex] ----- angles in an isosceles triangle

Substitute [tex]\theta = 3\alpha[/tex]

[tex]3\alpha + \alpha + \alpha = 180^o[/tex]

[tex]5\alpha = 180^o[/tex]

Divide both sides by 5

[tex]\alpha = 36^o[/tex]

Recall that: [tex]\theta = 3\alpha[/tex]

[tex]\theta = 3 * 36^o[/tex]

[tex]\theta = 108^o[/tex]

The area is then calculated as:

[tex]Area = \frac{1}{2}l^2 \sin(\theta)[/tex]

[tex]Area = \frac{1}{2}*14^2 \sin(108^o)[/tex]

[tex]Area = \frac{1}{2}*196 *0.9511[/tex]

[tex]Area = 93.21in^2[/tex]

Answer:

y = -27.6

Step-by-step explanation:

To solve for y, you need to isolate the variable on one side of the equation. [tex]5(y+25)=-13[/tex] ⇒ [tex]y + 25 = -2.6[/tex] ⇒ [tex]y = -27.6[/tex].

Answer:

-27.6

Step-by-step explanation:

[tex]5(y + 25) = -13[/tex]

First, distribute the problem.

[tex]5y + 125 = -13[/tex]

Secondly, subtract 125 from -13 and 125.

[tex]125 - 125 = 0[/tex]

[tex]-13 - 125 = -138[/tex]

Now, we are left with 5y = -138.

Lastly, we divide -138 by 5.

[tex]-138 / 5 = -27.6[/tex]

Therefore, y is -27.6.

Mrs. Giavis has 26 marbles in a bag. She has 13 blue marbles, 10 red marbles, and 3 yellow marbles. What is the probably that Mrs. Giavis will pick a blue marble, not replace it, and then randomly pick a red marble?

Answers

Given:

Total number of marbles = 26

Number of blue marbles = 13

Number of red marbles = 10

Number of yellow marbles = 3

To find:

The probability of getting a blue marble then a red marble (without replacement).

Solution:

Total number of marbles = 26

Number of blue marbles = 13

Probability of getting a blue marble is first draw is:

[tex]P(Blue)=\dfrac{\text{Number of blue marbles}}{\text{Total number of marbles}}[/tex]

[tex]P(Blue)=\dfrac{13}{26}[/tex]

[tex]P(Blue)=\dfrac{1}{2}[/tex]

After drawing 1 marble, the remaining number of marbles in the bag is 25.

Probability of getting a red marble is second draw is:

[tex]P(Red)=\dfrac{\text{Number of red marbles}}{\text{Remaining number of marbles}}[/tex]

[tex]P(Red)=\dfrac{10}{25}[/tex]

[tex]P(Red)=\dfrac{2}{5}[/tex]

Now the probability of getting a blue marble then a red marble (without replacement) is:

[tex]P(\text{Blue then red})=P(Blue)\times P(Red)[/tex]

[tex]P(\text{Blue then red})=\dfrac{1}{2}\times \dfrac{2}{5}[/tex]

[tex]P(\text{Blue then red})=\dfrac{1}{5}[/tex]

Therefore, the probability of getting a blue marble then a red marble (without replacement) is [tex]\dfrac{1}{5}[/tex].
