Answer: five sevenths
Step-by-step explanation:
To determine the probability of randomly drawing a consonant from the set of cards, we first need to identify the consonants in the given letters: M, A, T, H, F, A, N.
From this set of letters, the consonants are M, T, H, F, and N. There are 5 consonants out of a total of 7 letters.
To calculate the probability, we divide the number of favorable outcomes (drawing a consonant) by the total number of possible outcomes (drawing any letter).
The probability of randomly drawing a consonant is:
Number of favorable outcomes: 5 consonants
Total number of possible outcomes: 7 letters
Therefore, the probability of randomly drawing a consonant is 5/7.
Expressing it as a fraction, the probability is five sevenths.
Therefore, the correct answer is five sevenths.

Answer: 160
Step-by-step explanation:
Answer: 160m3
Step-by-step explanation:
For the first prism, you find the volume by multiplying the length of the prism by the width of the prism by the height of the prism.
V = w h l = 8m x 3m x 2m = 48m3
For the second prism, you do the same thing you did to the first one.
V = w h l = 4m x 4m x 7m = 112m3
Lastly, you add the volume of both prisms to get your answer.
48m3 + 112m3 = 160m3

What is a proportional relationship?A proportional relationship is defined as follows:
y = kx.
In which k is the constant of proportionality.
The constant for a pair (x,y) is given as follows:
k = y/x.
When x = 5/6, y = 2, hence the constant is given as follows:
k = 2/(5/6)
k = 12/5
k = 2.4.
When x = 25/6, y = 10, hence the constant is given as follows:
k = 10/(25/6)
k = 60/25
k = 2.4.
When x = 125/6, y = 50, hence the constant is given as follows:
k = 50/(125/6)
k = 300/125
k = 2.4.
Same constant, hence the table in fact represents a proportional relationship.

Which expressions are equivalent to the expression 3x2−5a3+2y4?
Select all that apply.
2y4−5a3+3x2, 2y4+3x2−5a3, 3x2−2y4+5a3, or 3x2+2y4−5a3
Answer:
The first two answers and the last one are correct.
Step-by-step explanation:
In order to check if the expressions are equivalent, look at the number in front (coefficient) and its sign (positive/plus or negative/minus), the letter (variable) and its exponent.
In the question the 3x² is a (positive or plus) +3x²
The 5a³ is a (negative or minus) -5a³
The 2y^4 is also (positive or plus).
All of the signs in the answers are the same as the question (as well as the number, letter, exponent) EXCEPT for the third answer has a different sign. It has NEGATIVE 2y^4 and POSITIVE 5a³ which are wrong.
The terms can be rearranged, but they MUST keep their positive or negative signs with them, and keep them the same sign as the original question.
It takes 10 mins to fill a bath with just the hot tap and 15 minutes to fill it just with the cold tap.
How long wikll it take to fill the bath if you run both taps at once?
Please give a equation or the steps of solving, thanks a lot!
===========================================================
Explanation:
Let's say the tub is 30 gallons. I'm picking this number because it's the LCM of 10 and 15. Picking the LCM means that later division operations result in a whole number.
The hot tap takes 10 minutes to fill the tub. Its rate is 30/10 = 3 gallons per minute.
Rate = (amount done)/(time)
The cold tap works at a rate of 30/15 = 2 gallons per minute.
When both taps are running at the same time, they combine to a total rate of 3+2 = 5 gallons per minute. Therefore, it will take 30/5 = 6 minutes if both taps are opened.
Time = (amount done)/(rate)
-------------------------
Another approach:
The hot water tap takes 10 minutes to do 1 job. That "1 job" refers to "fill the bathtub". The unit rate here is 1/10 of a job per minute.
Meanwhile, the cold tap has a unit rate of 1/15 of a job per minute.
The combined rate is 1/10 + 1/15 = 3/30+2/30 = 5/30 = 1/6 of a job per minute.
x = number of minutes it takes to fill the bathtub if both taps are going at once.
We can say:
(unit rate)*(time) = amount done
(1/6 of a job per min)*(x minutes) = 1 job
(1/6)x = 1
x = 6 minutes is the final answer
-------------------------
Another approach:
The template for problems like this is:
1/A + 1/B = 1/C
where
A = amount of time for the hot tap water (working alone)B = amount of time for the cold tap water (working alone)C = amount of time if the two taps work togetherWe end up with the equation
1/10 + 1/15 = 1/x
This can be rearranged into
(1/10+1/15)x = 1
and also rearrange into
(1/6)x = 1
Follow the steps mentioned earlier to end up with 6 minutes as the final answer

Find the percent change to the nearest whole percent
Answer:
40.63% to the nearest whole percent is 41
Step-by-step explanation:
(45 - 32) / 32) * 100 = 40.63 %
To round 40.63 to the nearest whole number consider the tenths’ value of 40.63, which is 6 and equal to or more than 5. Therefore, we have to round up: the whole number part of 40.63, 40, increases by 1 to 41, and the decimal point and all digits (.63) are removed...
40.63 rounded to the nearest whole number = 41

The sum the age of a boy and his sister is 32 years. If the boy is 6 years older than his sister, how old is his sister?
TYVM!! :)
Answer:
The sister is 13 years old.
Step-by-step explanation:
Let the boy's age = b.
Let the sister's age = s.
b + s = 32
b = s + 6
s + 6 + s = 32
b = s + 6
2s + 6 = 32
b = s + 6
2s = 26
b = s + 6
s = 13
b = 13 + 6
s = 13
b = 19
Answer: The sister is 13 years old.

At a school carnival, the diameter of the mat of a trampoline is 16 feet and the diameter of its metal frame is 18 feet. What is the length, in feet, of the metal frame that surrounds the trampoline? Use 3.14 for π and round your answer to the nearest tenth.
a
50.2 feet
b
56.5 feet
c
100.5 feet
d
113.0 feet
The length of the metal frame that surrounds the trampoline can be calculated by subtracting the diameter of the mat from the diameter of the metal frame and then multiplying by π.
The diameter of the mat is 16 feet and the diameter of the metal frame is 18 feet, so the difference is 18 - 16 = 2 feet.
The length of the metal frame can be calculated as follows:
Length = π * (difference in diameter) = 3.14 * 2 feet = 6.28 feet
So, the length of the metal frame is 6.28 feet, which is closest to option a, 50.2 feet. The answer is therefore a.

A polygon is shown:
A polygon MNOPQR is shown. The top vertex on the left is labeled M, and rest of the vertices are labeled clockwise starting from the top left vertex labeled, M. The side MN is parallel to side QR. The side MR is parallel to side PQ. The side MN is labeled as 5 units. The side QR is labeled as 7 units. The side MR is labeled as 3 units, and the side NO is labeled as 2 units.
The area of polygon MNOPQR = Area of a rectangle that is 15 square units + Area of a rectangle that is
square units. (Input whole numbers only, such as 8.) (5 points)
Answer:
The area of polygon MNOPQR = Area of a rectangle that is 15 square units + Area of a rectangle that is 2 square units.
Step-by-step explanation:
In the given polygon MNOPQR, side MN is parallel to side RQ and the side MR is parallel to side PQ
We will draw a perpendicular line from point O on the side RQ, which will intersect RQ at point S. So, we can now divide the whole polygon into two different rectangles MNSR and OPQS with the areas as A₁ and A₂ respectively.
In rectangle MNSR, length(MN) = 5 units and width (MR) = 3 units
According to the formula for Area of rectangle,
A₁ = (length)×(width)
A₁ = (5 units)×(3 units)
A₁ = 15 square units
Now in rectangle MNSR, side MN= side RS and side MR = side NS,
so RS= 5 units and NS= 3 units
That means, SQ= RQ- RS = 7-5 = 2 units
and OS= NS - NO = 3- 2 = 1 unit
In rectangle OPQS, we have length(SQ) = 2 units and width(OS) = 1 unit
So, A₂ = (length)×(width)
A₂ = (2 units)×(1 unit)
A₂ = 2 square units
So, the area of polygon MNOPQR = (Area of a rectangle that is 15 square units + Area of a rectangle that is 2 square units)
