Meaning that the 20th term is 58
Answer:
a₂₀ = 58
Step-by-step explanation:
the nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 1 and d = a₂ - a₁ = 4 - 1 = 3 , then
a₂₀ = 1 + (19 × 3) = 1 + 57 = 58

Three cards are randomly chosen from a deck of 52 cards without replacement. What is the probability that they will all be red?
The probability that all three cards will be red is [tex]\frac{2}{17}[/tex]
In a deck of cards, the total number of cards is 52.
The total number of red cards in a deck is 26 i.e., half the total number of cards.
Selection of 3 cards from 52 cards is done according to 52C3.
Selection of 3 cards from 26 red cards is done according to 26C3.
∴ Probability = [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex]
= [tex]\frac{26C3}{52C3}[/tex]
= [tex]\frac{2600}{22100}[/tex]
= [tex]\frac{2}{17}[/tex].
Hence, the probability that all three chosen cards from the deck of 52 cards will be red is [tex]\frac{2}{17}[/tex].

How to solve an equation?To solve linear equations, utilize the steps that are provided below.
Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12
⇒ 7z – 3z + 4 = 12
⇒ 4z = 12 – 4
⇒ 4z = 8
⇒ z = 8/4
⇒ z = 2
See, that was so simple, using the mentioned methods, every linear equation can be solved easily.
If 140 paper are used in 80 days then
in days 80 ⇒ 140 pack paper used
in day 1 ⇒ 140/80 pack paper used
in days 30 ⇒ 140/80 × 30
⇒ 21/4 pack paper used or 5.25 pack paper used

The length of a rectangle is 4 less than 5 times its width? If the perimeter of the
rectangle is 112 square feet, what is the length and width of the rectangle?
The length and width of the rectangle is 46 feet and 10 feet respectively.
Let the length of the rectangle be x and the width of the rectangle be y.
Now, the length of the rectangle is 4 less than 5 times its width.
Therefore,
x = 5y - 4
The perimeter of a rectangle is given as two times the sum of its length and breadth.
Perimeter = 2( length + breadth)
P = 2( x + y)
Now, the perimeter of the rectangle is 112 square feet.
Therefore,
112 = 2( 5y - 4 + y)
( 112 /2) = 5y - 4 + y
6y - 4 = 56
6y = 56 + 4
6y = 60
y = ( 60 / 6)
y = 10
Now,
x = 5y - 4
x = 5 × 10 - 4
x = 50 - 4
x = 46
So, the length of the rectangle is x = 46 feet and the breadth of the rectangle is y = 10 feet.

Prove the following.
If VZ ≅ VY and WY ≅ XZ , then VW ≅ VX .
The expression of the segment as the sum of the parts, gives VW = VX
How can the segment parts be used to prove that VW = VX?The given parameters are;
VZ = VY, WY = XZ, then VW = VX
From the given drawing obtained from a similar question, we have;
VZ = VW + WY (Segment Addition Postulate)
VY = VX + XZ, by segment addition
Therefore;
By substitution property, we have;
VW + WY = VX + XZ
Which gives;
VW + WY = VX + WY (substitution)
VW + WY - WY = VX + WY - WY

Solve each formula for the indicated variable. V = lwh , for w
The solution of the given formula V = lwh for the variable w is V/lh.
According to the given question.
We have a formula.
V = lwh
Since, we have to solve this given formula V = lwh for the variable w.
Which means we have to write separate variable w to one side from the other variables which are in the given formua V = lwh .
Thereofre, the solution of the given formula V = lwh for the variable w is given by
V = lwh
⇒ V/l = wh (dividing both the sides by l)
⇒ V/lh = w (dividing both the side by h)
or w = V/lh
Hence, the solution of the given formula V = lwh for the variable w is V/lh.

The grounds crew needs to mow the football field before their next game. Mr. Comb can mow the field in 5 hours, and Mr. Ramset can mow the same field in 4.5 hours. If they worked together, how long would it take for both of them to mow the field if they worked together? Round your answer to the nearest minute.
Answer:
2 hours and 22 minutes
Step-by-step explanation:
Rate x Time = jobs
Mr. Comb's rate is 1 field in 5 hours or 1/5.
Mr. Ramset's rate is 1 fiend in 4.5 hours.
If we take the time and rate that it takes Mr. Comb's to mow one field and add it to the time and rate that it takes Mr. Ramset's to move one field we can find out how long it takes them to mow one field together

1/5T + 1/4.5T = 1 We need a common denominator. I just multiplied 5 x 4.5 for get 22.5 Rewrite 1/5 and 1/4.5 with a common denominator or 22.5 we get the equivalent fractions that we can add together.
4.5/ 22.5T + 5/22.5T = 1 Add the fractions together
9.5/22.5T = 1 We want to solve for T, so we will multiply both sides of the equation by 22.5/9.5
9.5/22.5(22.5/9.5)T= 1 22.5/9.5
T = 22.5/9.5 When I divide these, I get 2 35/95 hours. I need to change the fraction part of an hour to minutes. I will use the unit multiplies 60 minutes/ 1 hour.
35hours/95 (60 minutes/1 Hour) = 22.10526331579. I need to round this to the nearest minutes which will be 22 minutes.
