Find radical A and B
Answer:
a = 5 and b =6
Step-by-step explanation:
rationalize the denominator by multiplying the numerator and the denominator of the fraction by the inverse of the denominator: 2 - sqrt5.
((40 + 17 sqrt5) * (2-sqrt5)) / ((2+sqrt5) * (2-sqrt5)) = -5 - (6*sqrt5) / -1
multiply the numerator and the denominator by -1: 5 + 6sqrt5
a = 5 and b = 6
The required value of A = 5 and B = 6
[tex]\frac{40+17\sqrt{5} }{2+\sqrt{5} }= a+b\sqrt{5}[/tex]
A = ? B=?
Fraction is defined as the number of composition constitute the Whole.
[tex]\frac{40+17\sqrt{5} }{2+\sqrt{5} }= a+b\sqrt{5}[/tex]
multiply numerator and denominator by 2-√5
(40+17√5)(2-√5) / (2+√5)(2-√5) = a+b√5
80-40√5+34√5-85/4-5 = a+b√5
5+6 = a+b√5
Thus, the required value of A = 5, B = 6

Comment
This is a good question to estimate the answer. That will get rid of the ones you don't have to check - maybe.
123 miles in 3 hours = 123/3 = 40 about Too far away. Not answer
96 miles in 3 hours = 100 / 3 = 33 about. This is one you should check.
288 miles in 9 hours = 270/9 = 30 about. Another one to check
66 miles in 3 hours = 66/2 = 33 Not right.
310 miles in 10 hours = 310/10 = 31 Not right
Some of these do not need to be rounded to get the answer. If the division is the same as the question and it does not come to 32 then it will not be included in the answer.
B gives 32 miles / hour. B is one of the answers
C gives 32 miles / hour. C is one of the answers.

20. The total mass of three boxes, A, B, and C, is 1.95 kg. The mass of Box A is 700 g. The mass of Box B is 4 times the mass of Box C. What is the mass of Box B in kilograms?
Answer:
Mass of B in Kg = -558.44kgStep-by-step explanation:
LET'S DO THIS!
Total mass of A, B and C = 1.95kg
Mass of A = 700 kg
Mass of B = 4x the mass of c (4 x C) which is 4c
Mass of C = ? ( let's call it C )
Adding all together700 + 4c + C = 1.95
Add like terms700 + 5C = 1.95
5C = 1.95 - 700
5C = -698.05
C = -698.05 ÷ 5
C = -139.61To find B now Remember they said B is 4 times the mass of C and C = -139.61therefore B = 4 × -139.61
B = -558.44 kg To check if we are correct, we add the masses of A, B and C to see if it equals their total mass which is 1.95kgUsing your calculator:= 700 + ( -558.44 ) + ( -139.61 )
= 700 - 558.44 -139.61
= 1.95 kg
Which makes us CORRECT ✅.

Never say anything is too hard because one day this will be second nature solving these fractions
Answer: 12.5 hours watching TV
Step-by-step explanation:
Step 1: We know this is an "in all" question, so we first need to find the fractions to add up.
Each dot on the graph represents 1 of each fraction. For example, the dot above the "1/4" means that 1/4 hours were spent watching TV, and the 3 dots above the 1 means that he watched TV for 1 hour in a row 3 times, so the total number of hours for 1 would be 3x1, or 1+1+1.
So we have:
1/4
1/2
3/4
3/4
3/4
1
1
1
1 1/4
1 1/4
1 1/4
1 1/4
1 1/2
(again, each dot represents 1 of each)
Step : Convert these to decimals so it's easier to add
1/4--> 0.25
1/2--> 0.5
3/4--> 0.75
3/4--> 0.75
3/4--> 0.75
1--> 1
1--> 1
1--> 1
1 1/4--> 1.25
1 1/4--> 1.25
1 1/4--> 1.25
1 1/4--> 1.25
1 1/2--> 1.5
0.25+0.5+0.75+0.75+0.75+1+1+1+1.25+1.25+1.25+1.25+1.5= 12.5 hours in all

Answer:
1. 180 degrees
2. 4
3. 8π
4. 8:1
5. 12.5 feet
6. 3 revolutions
7. π/2
8. 64π
Step-by-step explanation:
1. For the first question, we are given that there are 120 degrees in 1/3 of a circle. This makes sense because a complete circle makes up 360 degrees (3*(1/3)). Two figure out how many more degrees there are in 5/6 circle, we first need to figure out how many degrees are in 1/6 of a circle and then 5/6 of a circle. If there are 120 degrees in 1/3 of a circle, there are 120/2 or 60 degrees in 1/6 of a circle (1/6 is half of 1/3). If we multiply this by 5 (because 1/5 * 5 = 5/6), we get that 5/6 of a circle is 60*5 or 300 degrees. That being said, the question is asking us how many more degrees there are in 5/6 circle than 1/3. We know that there are 120 degrees in 1/3 of a circle, so we can do 300 - 120 to figure out the answer, which comes out to be 180 degrees.
2. For the second question, we are given that the area of the circle is 4π. We know that the formula for the area of a circle is [tex]\pi r^{2}[/tex], which means the radius squared of the circle given is 4 (divide by π). If we take the square root of 4, we get the radius of our circle to be 2. Now, all we have to do is figure out the diameter. The radius is the distance between a point on the circle and the center. The diameter is just double this distance because it is the distance between one point on a circle and another point on the exact opposite side (the diameter line segment goes through the center). Since the radius is 2, the diameter has to be 4.
3. For the third question, we are given that the radius of a circle is 4 and we need to figure out the circumference (q). We know that the formula for the circumference of a circle is πd, or 2πr (r is the radius). We can plug the known radius into the equation and solve for the circumference. If we plug in r = 4, we get that the circumference (q) is 2(4)(π), or 8π.
4. For the fourth question, we are given that the radius of circle Q is 4 times the size of the diameter of circle R. We know that the diameter of any circle is just double the size of the radius. This means that, if the radius of circle Q is four times the diameter of circle R, the diameter of circle Q is 4(2) or 8 times the size of the diameter of circle R. This can be represented in ratio form as 8:1 (as in, if the diameter of circle R was 1, the diameter of circle Q would be 8, which is 8 times the size).
5. For the fifth question, the distance traveled in one revolution of a circle is the same as the circumference of the circle. You can imagine a circle and a point on it that is touching the ground. The circumference of this circle (the length of the circle) is the same as the distance traveled between the time the point touches the ground to the time it touches the ground again. Please feel free to let me know if this doesn't make sense. I will try to draw it out. Anyway, we are given the diameter of this wheel (4 feet), and we know that the circumference of a circle is π*d, so the circumference, in this case, would be 4π, which is approximately 12.5 feet.
6. For the sixth question, we just need to figure out the circumferences of the two wheels and compare them. If we go back to the fifth question, we know that the distance traveled by a wheel in one rotation is the same as its circumference. Let's say that the radius of the rear wheel is x. This means that the radius of the front wheel is 3x. The circumference of a circle is 2πr, which means the circumference of the front wheel is 6πx and the circumference of the rear wheel is 2πx. The circumference of the front wheel is 3 times the size of the rear wheel's circumference, which means that it will take 3 revolutions of the rear wheel to complete 1 revolution of the front wheel
7. For the seventh question, if AD is a half circle, that means the side of the square that connects A and D is the diameter of the circle. We know that this diameter is 2 because the length of each side of the square is 2. If the diameter is 2, that means the radius of the half-circle is half of that, or 1. The area of a circle is πr^2, so this circle has a radius of π (r^2 is 1). A half-circle has half of the area of a full circle, so the area of this half-circle would be π/2.
8. For question 8, we know that the circumference of circle A is 8π, and the circumference of any circle is 2πr. This means the radius of circle A is half of 8, or 4. We are given that the radius of circle B is twice the radius of circle A, which means the radius of circle B is 8. The area of a circle is πr^2, and r^2 for circle B is 8^2 or 64. Therefore, the area of circle B is 64π.

I then realized that I would be late if I kept walking.
I ran the rest of the way. I run twice as fast as I walk.
Find:
The number of minutes in total did it take me to get from home to work
Step-by-step explanation:
Had I kept walking, the second half of my trip would have taken 10 more minutes.
By doubling my speed for the second half of my trip,
I halved the amount of time it took me to finish.
So, the second half of my trip took 5 minutes, for a total trip time of 10+5 = 15 minutes.

11. Since Angle RST = 60 degrees, Angle RTS = 60 degrees.
Triangle STU is a right triangle, so Angle STU and Angle SUT are both 45 degrees.
Angle RTS + Angle STU + Angle UTQ = 180 degrees
60 + 45 + Angle UTQ = 180
Angle UTQ = 180 - 105

8.3.10 Dave is playing blackjack at his local casino. He starts with $1,000 and on each hand he bets 50% of his money. If he wins a hand, then he wins whatever he bet, but if he loses a hand, then he loses whatever he bet. After playing 5 hands, he has won 3 hands and has lost 2 hands. How much money does Dave have after the 5 hands? Does it matter which 3 of the 5 hands he won?
Hint: It's often best to think of percent increases and decreases in terms of multiplying the original quantity by some number.
Hint: Suppose Dave has $x before betting half his money on a hand. How much will he have if he wins? How much will he have if he loses?
Answer:
The amount Dave got after 3 wins and 2 loose is $843.75. The order of win and loose doesn't matter.
Step-by-step explanation:
- We are given with a word problem
- We are asked to find the amount he had after 5 hands
- We can do this in two steps
Step 1 : Identifying the percentages
Step 2 : Finding the amount left
Step 1 of 2
We are given with a word problem. He bets 50% of his money. If he wins he get his bet, if he loose he will loose the money too. If he wins he will get the money as 150%.
That is, 1.5
If he loose he will loose money by 50%
That is, 0.50
Step 2 of 2
The amount got after 5 hands with 3 wins and 2 loose is,
[tex]$$\begin{gathered}1000 \times(1.5)^{3} \times(0.5)^{2}=1000 \times 3.375 \times 0.25 \\1000 \times 0.84375=843.75\end{gathered}$$[/tex]
The amount of money that have after the 5 hands will be 843.75 and 3 of the 5 hands he won do not matter.
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.
He takes 50% of his cash. If he wins, he receives his wager; if he loses, he also forfeits the money. If he prevails, he will receive 150% of the prize.
The amount Dave got after 3 wins and 2 losses is $843.75. The order of win and loss doesn't matter.
The amount got after 5 hands with 3 wins and 2 loose is,
⇒ 100 × 1.5³ × 0.5² = 843.75
Hence "After the five hands, he will have 843.75 in total, and three of the five hands he won are irrelevant".

The number of meters Robert will beat Sam is 12 meters.
Step-by-step explanation:
Given:
When Paul crossed the finish line of a 60-meter race, he was ahead of Robert by 10 meters and ahead of Sam by 20 meters. Suppose Robert and Sam continue to race to the finish line without changing their rates of speed.
Find:
the number of meters by which Robert will beat Sam
Step 1 of 1
When Paul finishes, Robert has run 60-10=50 meters and Sam has run 60-20=40 meters.
Therefore, when Robert and Sam run for the same amount of time, Sam covers [tex]$\frac{40}{50}=\frac{4}{5}$[/tex] of the distance that Robert covers. So, while Robert runs the final 10 meters of the race, Sam runs [tex]$\frac{4}{5} \cdot 10=8$[/tex] meters.
This means Robert's lead over Sam increases by 2 more meters, and he beats Sam by 10+2=12 meters.

Answer:
12 people
Step-by-step explanation:
This is a problem that involves common ratios. 7 people bought jerseys for every 2 people who bought programs. We need to figure out how many people bought programs if 42 people bought jerseys. If we let the number of people who bought programs be x, we can set up an equation like this:
[tex]\frac{2}{7}=\frac{x}{42}[/tex]
If we cross multiply, we get the following:
[tex]7x=84[/tex]
We can solve for x by dividing by 7, and getting that x = 12. This means that 12 people bought programs.
