And pls find the radical

How To Calculate Distance Between Two Points (-3,2) And (3,0).And Pls Find The Radical

Answers

Answer 1

√74
Explanation:
To calculate the distance use the
distance formula
d=√(x2−x1)^2+(y2−y1)^2

−−−2
where
(x1,y1)and (x2,y2)
are 2 coordinate points
The 2 points here are (-3 ,7) and (4 ,2)
let(x1,y1)=(−3,7) and (x2,y2)=
(4,2)⇒d=√(4−(−3))2+(2−7)2=√49+25=√74←in radical form

But if you only want one answer, then do 405/100

Hope this helps! :)
401/99 and 802/198. this can be proven by dividing 401 by 99, and dividing 802 by 198. you also know these are equivalent fractions since 401/99 times 2 is equal to 802/198 (recognizing this is not necessary, but it could help). hope this helps :)

A. Are the expressions 3(m−2) + 2(m−2) and 5(m−2) equivalent expressions?

B. In two or more complete sentences, justify your answer to A.

Answers

The answer is yes. If you solve both expressions it would be 5m-10.

Answer: yes, this is because when you solve the first equation then your answer will be 5(m-2). You do this by distributing 3 to m & 2 (multiply), then you will distribute 2 to m & 2 (also multiply).

Solve for b.

b - 7 = -20
A. b = -27
B. b = -13
C. b = 13
D. b = 27

Answers

Answer:

B. b = -13

Step-by-step explanation:

b - 7 = -20

move variables and numbers to different sides of the equal sign by adding 7 to both sides

b - 7 + 7 = -20 + 7

b = -13

your answer would be -13 :) have a good day

Because of demand, concert tickets that normally sell for 89.99 each are marked up 20%, If Mark wishes to purchase 8 tickets, how much will he pay in total?

20 points will be given

Answers

Answer:$863.92

Step-by-step explanation:20% of 89.99 is 18

89.99x8=719.92

18×8=144

719.92+144=

863.92

Answer:

he will pay 864 dollars in total

Step-by-step explanation:

first we have to find 20% of 90 (i just rounded 89.99 to 90).

20% = 1/5, and 1/5 in decimal form is 0.20.   (you can find the decimal value by multiplying the numerator and denominator by 10/10 and then simplifying it)

0.20 * 90 is 18, so we then add that to 90 making 108.

next, since Mark is buying 8 tickets, we multiply 108 by 8, giving us 864

therefore, 864 is our final answer

3. Given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solution.

Answer:

Step-by-step explanation:

To solve the system using elimination, first multiply the bottom equation by 2. Write the new system of equations. (1 point)

5x + 2y = 7

6x –2y = 4

Why is this multiplication allowed? (1 point)

Because the entire equation was multiplied by the same number, the equation remains the same.

What variable will be eliminated when the equations are combined after  the multiplication? (1 point)

The Y variable

Next, add the equations together. Your answer should be a single equation with one variable. (1 point)

11x = 11

Solve the equation for x. (1 point)

X = 1

What is the solution to the system of equations? (1 point)

X = 1 and Y = 1 so the answer is (1, 1)

(If you solve this again, but eliminate the X variable, you will still receive that answer 1, so Y = 1)

Sam’s discount shoes is have a 40 percent off sale. A — use the percent ruler at right to find how much Lorna will save on her purchase of 80 dollar professional basketball shoes. B What will she pay for the shoes?

Answers

Answer:

A, 32

B, 48

Step-by-step explanation:

Since the discount is 40% off, she will save 40% of the 80 dollar shoes, which is 40% of 80 dollars. 40 * 80 = 3200, and 3200/100 = 32 dollars worth of savings. She will pay a total of 80 dollars minus the 32 dollar discount to get a total of 48 dollar payment.

Answer:

40% off that means her shoes will be 60% of the value so 80* 0.6 or 60% = $48 she will pay and 32 she will save

Morgan has an 8 1/2 foot board that must be cut into boards that are feet long. How many of the smaller boards can he get from the 8 1/2 foot board?

Which of the following equations could you use to solve the problem?
x * 8 1/2 = 5/6
8 1/2 * x = 5/6
5/6 * 8 1/2 = x
8 1/2 / 5/6 = x

Answer:

8 1/2 / 5/6 = x

Step-by-step explanation:

8 1/2 foot board to be cut into 5/6 feet boards.

Number of smaller boards is:

8 1/2 ÷ 5/6 = 17/2 ÷ 5/6 = 17/2 × 6/5 = 51 / 5 = 10 (the whole part)

A Bear in the Army While traveling through Iran during World War II, a group of Polish soldiers encountered a young boy with an intriguing possession available for trade: a bear cub. The soldiers promptly bought the cub, named him Wojtek, and took him to join the rest of their unit. The playful bear adapted well to military life. However, when the unit was sailing for Italy, officials refused to allow the bear on the ship, saying that only soldiers were permitted. The solution was both obvious and extraordinary: the soldiers arranged for Wojtek to be officially enlisted in the army. As an enlisted soldier, he could accompany the men on their mission. "He didn't receive money," recalled one former soldier in an interview with the BBC World Service, "but was officially a Polish soldier."
