The surface area of the prism is 72 cm².
What is surface Area?The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface.
We have a prism in the shape of cuboid.
length = 6 cm, Width = 3 cm, Height = 2 cm
So, Surface Area of Cuboid
= 2 (lw + wh + lh)
= 2 ( 18 + 6 + 12)
= 2 (36)
= 72 cm²
Thus, the surface area of prism is 72 cm².

Suzi bought 5 packages of M&M's, and each package contained 18 candy pieces. She opened the first package and counted 4 green pieces. She then counted 3 green pieces in the second package. Which statement about the candy pieces in the remaining packages is best supported by this information? A. There are fewer than 14 green pieces in all 5 packages. B. There are between 15 and 20 green pieces in all 5 packages. C. There are at least 25 green pieces but no more than 50 in all 5 packages. D. There are more than 50 green pieces in all 5 packages.
Answer: The correct answer is option B: There are between 15 and 20 green pieces in all 5 packages
Step-by-step explanation: The most important factor has been given which is, "Which statement about the candy pieces in the remaining packages is best supported by this information."
The information given is such that, the first package she opened had 4 green pieces and on this basis we can safely assume that all other packages have 4 green pieces as well. The second package had 3 green pieces and this based on this too we can safely assume that all other packages had 3 green pieces. Hence, all 5 packages can either have a total of 4 x 5 green candies which equals a total of 20 green pieces or, all 5 packages can have a total of 3 x 5 green candies which equals a total of 15 green pieces.
So according to Suzi's experiment, there are between 15 and 20 green pieces in all 5 packages.

together preston and horatio have 49 video games. horatio has 11 more then preston. how much does each person have
each person has about 19 each
all you have to do is 49-2=38
38 divided by 2 = 19
Horatio has 30 video games and Preston has 19
Step-by-step explanation:Set up an equation:
x = Games horatio has
Since theres two people we will give x the coefficient of 2
You get 11 from how much more horatio has
49 is the total
The Equation
49 = 2x + 11
Solve
49 = 2x + 11
-11 - 11
38 = 2x
19 = x
Preston has 19 video games and since horatio has 11 more horatio has 30 video games
Jackie made 12 quarts of lemonade. Jackie says she made 6 pints of lemonade. Complete the explanation of Jackie's error. Then find the correct number of pints of lemonade. Jackie divided the number of quarts by 2. There are pints in each quart. She should have 2; so Jackie made pints of lemonade.
Answer:
Jackie is incorrect. Since 2 pints equal 1 quart, she would need to multiply 12 by 2 to get the correct answer of 24 pints.

Joan, Kylie and Lillian all celebrate their birthdays today. Joan is 2 years younger than Kylie, and Kylie is 3 years older than Lillian. Which of the following could be the combined age of all three birthday celebrants today?A. 51
B. 52
C. 53
D. 54
E. 55
Answer: Option 'B' and 'D' are correct.
Step-by-step explanation:
Since we have given that
Let the age of Lilian be 'x'
Let the age of Kylie be 'x+3'.
Let the age of Joan be 'x+3-2=x+1'.
So, According to question, we get :
Total sum of all three birthday celebrants today would be
[tex]x+x+3+x+1=3x+4[/tex]
If we put 52, we get that
[tex]3x+4=52\\\\3x=52-4\\\\3x=48\\\\x=\dfrac{48}{3}=16[/tex]
If we put 55, we get that
[tex]3x+4=55\\\\3x=55-4\\\\3x=51\\\\x=\dfrac{51}{3}\\\\x=17[/tex]
Hence, Option 'B' and 'D' are correct.
Using algebra, we express each person's age in variables, create a relationship between them, and find that the only option that can represent their combined age as a sum of 3L + 4 is 52. Therefore, option B is the correct answer.
To solve this problem, we can begin by assigning variables to each person's age and then creating equations based on the information provided. Let's let the variable L represent Lillian's age, K represent Kylie's age, and J represent Joan's age.
From the problem, we know that:
Joan is 2 years younger than Kylie: J = K - 2
Kylie is 3 years older than Lillian: K = L + 3
Now, using the second equation, we can express Joan's age in terms of Lillian's:
Substitute the value of K from the second equation into the first: J = (L + 3) - 2
This simplifies to: J = L + 1
Now we can express the combined age of Joan, Kylie, and Lillian:
Combined age: J + K + L
Substitute J and K with the expressions in terms of L: (L + 1) + (L + 3) + L
Add them: 3L + 4
Now, we have to check which option is divisible by 3 when 4 is subtracted from it because the combined age should be in the form 3L + 4. Among the options given:
A. 51 - 4 = 47 (Not divisible by 3)
B. 52 - 4 = 48 (Divisible by 3)
C. 53 - 4 = 49 (Not divisible by 3)
D. 54 - 4 = 50 (Not divisible by 3)
E. 55 - 4 = 51 (Not divisible by 3)
The correct answer is option B, which makes the combined age of Joan, Kylie, and Lillian equal to 52 years.

The temperature was very cold then it dropped 10 degrees and then it increased 40 degrees the temperature is now 16 degrees. What is the starting temperature?
Answer:
The initial temperature was To = -14 degrees
Step-by-step explanation:
Solution:-
- We will take the starting temperature to be = Ti
- The final temperature, Tc = 16 degrees
- We are given that there is a drop of 10 degrees from initial temperature To. We can mathematically express this as:
To - 10
- Then there is a rise of 40 degrees after the drop of 10 degrees. The mathematical expression would be:
To - 10 + 40
- The current temperature is Tc. We can equate the expression developed to final temperature:
To - 10 + 40 = Tc
- Solve for To:
To = 16 - 40 + 10
To = -14 degrees
Answer:
-14 degrees
Step-by-step explanation:
In this question, we are asked to calculate the starting temperature if we know what the temperature is now and the kind of temperature change that has happened.
Now, since we do not know the initial temperature , let’s call it x
from the question, it dropped by 10 and increased by 40 and finally with a temperature of 16.
mathematically
x-10+40= 16
x+30 = 16
x = 16-30
x = -14

Answer:
20
Step-by-step explanation:
Because it is a square table, that means all the sides are even. And to find the area, we do Height * Base. But again, because they're even, we would just need to find 2 numbers that multiply to be 400. And that number, is 20. 20 * 20 = 400. So the length of one side is 20.

QUESTIONING STRATEGIES
If a cone shares a base with a cylinder, and the
volume of the cylinder is given, along with the
heights of the cylinder and of the cone, how could
you find the volume of the cone?
Answer:
cone volume = cylinder volume times 1/3 the ratio of cone height to cylinder height
Step-by-step explanation:
Let h1 and V1 represent the height and volume of the cylinder, and h2 and V2 the height and volume of the cone.
We are told they have a common base area (B), so ...
V1 = Bh1 ⇒ B = V1/h1
V2 = (1/3)Bh2 = (1/3)(V1/h1)h2
The volume of the cone is ...
V2 = h2/(3h1)×V1
"one-third the ratio of cone height to cylinder height, multiplied by the cylinder volume."

Answer:
K = 51
Step-by-step explanation:
Since the triangles are similar, the angles are the same measure.
<K = <F
We can find angle F since the angles of a triangle add to 180
D + G + F = 180
59+70 +F = 180
Combine like terms
129+F = 180
Subtract 129 from each side
129-129+F = 180-129
F = 51
K = F = 51
Answer:
51°
Step-by-step explanation:
Angle K corresponds to Angle F
Angle F = 180 - 70 - 59
Angle F = 51°
What is the value of a?
Answer:
a = 13
Step-by-step explanation:
The three angles of any triangle MUST add up to 180°. Thus, 3a + 8a + 37 = 180, and 11a = 180 - 37 = 143.
If 11a = 143, then a = 143/11 = 13
a = 13
Answer:
a = 13
Step-by-step explanation:
8a + 3a + 37° = 180°
11a + 37° = 180°
11a = 180° - 37°
11a = 143°
a = 143/11
a = 13

At the U.S. Open Tennis Championship, a statistician keeps track of every serve that a player hits during the tournament. The statistician reported that the mean serve speed of a particular player was 100 miles per hour (mph) and the standard deviation of the serve speeds was 10 mph.
Using the z-score approach for detecting outliers, which of the following serve speeds would represent outliers in the distribution of the player's serve speeds?
Speeds: 65 mph, 110 mph, and 120 mph.
Answer:
The speed of 65 mph is an outlier in the distribution of the player's serve speeds
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 100 mph
Standard Deviation, σ = 10 mph
Formula:
[tex]z_{score} = \displaystyle\frac{x-\mu}{\sigma}[/tex]
Outlier on basis of z-score:
Any z-score greater than 3 or less than -3 is considered to be an outlier. This rule of thumb is based on the empirical rule.Calculation of z-score:
[tex]x = 65\Rightarrow z = \dfrac{65-100}{10} = -3.5\\\\x = 110\Rightarrow z = \dfrac{110-100}{10} = 1\\\\x = 120\Rightarrow z = \dfrac{120-100}{10} = 2[/tex]
Thus, the speed of 65 mph is an outlier in the distribution of the player's serve speeds as the corresponding z-score is less than -3.

Find the number of strings of six lowercase letters from the English alphabet, which satisfies the given conditions. Six lowercase letters contain the letters a and b in consecutive positions with a preceding b, with all the letters distinct.
Answer:
The answer is 1,275,120
Step-by-step explanation:
The goal of this is to determine the number of strings of strings of six lowercase letters from the English alphabet that contain the letters a and b in positions consecutive with a preceding b, with all the letters distinct.
Now,
As the letters a and b are consecutive, the possible string outcomes are in this form:
ab_ _ _ _
_ab_ _ _
_ _ab_ _
_ _ _ ab_
_ _ _ _ ab
As seen here, ab can denoted in five locations as in C (5, 1) = 5 ways
we use the permutation for the order of the letters to be needed.
so,
n= 24, r =4
p (24, 4) = 24ǃ /( 24 - 4)ǃ
= 24ǃ /20ǃ
=255,024
Now, the number of possible strings is 5* 255.024 = 1,275,120.
In conclusion there are 1,275,120 number of strings of six lowercase letters from the English alphabet contain the letters a and b in consecutive positions with a preceding b, with all the letters distinct.
