Alan says that two lines in the coordinate plane are perpendicular if and only if the slopes of the lines are m and 1m. Identify and correct two errors in Alan’s statement.

Answers

Answer:

First, two lines are perpendicular if one has slope m, and the other has slope -1/m (Not 1m as Alan says)

That is the first error of Alan.

Now, there is another error.

If m = 0, then -1/m tends to minus infinity (in this case we would have a vertical line).

But we can not really divide by zero, so we should state that:

m can not be zero, if a line is horizontal, the perpendicular line must be vertical.

1. Given x=5, plug x into y=10x-2.
a. 38
b. 12.
C. 13
d. 48

Answers

Answer:

D. 48

Step-by-step explanation:

y=10x-2 is our equation

If x is 5, then multiply 10 by 5. You get 50.

Subtract 2 from that. You get 48.

Answer:

D, 48

Step-by-step explanation:

Given x=5, plug x into y=10x-2

First you should plug the given x into the x in the equation. And put () around it.

y=10(5)-2

Now you multiply 10 by 5 and you get 50.

y=50-2

Now the last step is to subtract 2 from 50 which you will end up getting y=48. So the answer is y=48 which is letter D.

y=48

Find x so that l is parallel to m.

Answers

Answer:

Step-by-step explanation:

(10x + 17)° = 87° + 5x° (This is because of the rule of corresponding angles)

=> 10x° = 87° + 5x° - 17°

=> (10x - 5x)° = 87° - 17°

=> 5x° = 70°

=> x° = ( 70/5 )°

=> x° = 14°

Therefore x = 14°

You are preparing for a trip to Canada. At the time of your trip, each U.S. Dollar is worth 1.293 Canadian dollars and each Canadian dollar is worth 0.773 U.S. Dollar. a. You exchange 150 U.S. Dollars for Canadian dollars. How many Canadian dollars do you receive?

Answers

Answer:

193.95 Canadian dollars

Step-by-step explanation:

Given: Each U.S. Dollar is worth 1.293 Canadian dollars and each Canadian dollar is worth 0.773 U.S. Dollar.

To find: Value of 150 U.S. dollars in terms of Canadian dollars

Value of 1 U.S. dollar = 1.293 Canadian dollars

To find 150 U.S. dollars in terms of Canadian dollars, multiply 150 by 1.293

Value of 150 U.S. dollars in terms of Canadian dollars = 150 × 1.293 = 193.95 Canadian dollars

Answer:
9: 1/36 chance of getting the same number on both dice
10: a) 5 b) 4/25

Explanation:
9: a die has 6 sides with each number. So the chance of getting a number on a dice once is 1/6. The second dice is the same with 1/6 chance. But to have them both be the same number means you have to multiply the probability. (1/6)/(1/6)=1/36

10:
a) 1/4 of the discs are blue, meaning you have multiply 1/4 by 20 which equals 5
b) the probability of getting a red is 12/20. So the probability of not getting red is 8/20. But both simultaneously, would mean for multiplying them. 8/20 •8/20=64/400 Then simplified to 4/50.

*im not super sure about 10 b. Sorry :/

For his art project, Dorian is using square tiles of different sizes and colors to make a mosaic. The first three tiles are: 1. A = 5 cm2 2. A = 7 cm2 3. A = 9 cm2


which tile's side lengths will Dorian need to estimate?

Answers

Answer:

3cm²

Step-by-step explanation:

Since the sizes are square tiles, to know the tile's side lengths that Dorian need to estimate, we will use the formula for calculating the area of q square

Area of a square = L²

L is the side length of the tiles

For the tiles with area 7cm²

7 =  L²

L² = 7

L = √7

L = 2.65cm

For tiles with area 5cm²

5 =  L²

L² = 5

L = √5

L = 2.24cm

For tiles with area 9cm²

9 =  L²

L² = 9

L = √9

L = 3.0cm

Since for all the square tiles the length of the tile is ≤ 3 cm, then the  tile's side lengths that Dorian will need to estimate is approximately 3cm

Answer:

I think 40 miles because 5034 divided by 125 is 40.272
