What type of transformation happened from (x,y) --> (-x,y)?
-----
A.Rotation 90*
B.Reflection over the y-axis
C.Translation left 1
D.Reflection over the x-axis

Answers

Answer 1

Answer:

B

Step-by-step explanation:

This is a reflection over the y-axis. The x value is changing sign while the y value is staying the same. The general rule for a reflection over the y axis is  (x,y) --> (-x,y), and similarly for a reflection over the x axis is (x,y) --> (x,-y). When you reflect a point over an axis, you flip the sign of the opposite value.

Answer 2
the answer would be B

Ryan has a bag that contains strawberry chews, cherry chews, and watermelon chews. He performs an experiment. Ryan randomly removes a chew from the bag, records the result, and returns the chew to the bag. Ryan performs the experiment 37 times. The results are shown below:

A strawberry chew was selected 8 times.

A cherry chew was selected 12 times.

A watermelon chew was selected 17 times.


Based on these results, express the probability that the next chew Ryan removes from the bag will be cherry or watermelon as a decimal to the nearest hundredth.

Answers

Answer:

32.43%

Step-by-step explanation:

Since there are a total of 37 tests and cherry was selected 12 times, the probability would be 12/37.

12(100/37)

32.43

The probability that it will be a cherry or watermelon is; P(Cherry or water melon) = (12 + 17)/37 = 0.51

How to find the Probability?

We are told that Ryan performs the experiment a total of 37 times.

From the experiment he got;

Strawberry = 8 times

Cherry = 12 times

Watermelon = 17 times

Thus, probability that it will be a cherry or watermelon is;

P(Cherry or water melon) = (12 + 17)/37 = 0.51

so basically either -2 or 2

Question B: Tony added 3 fish to his pond each day for 21 days.

This meaning you have to multiply 3 x 21 or add 3 twenty-one times.

3 x 21 = 63 | 3 + 3 + 3 + 3 + 3 + 3 + 3...

Which scenarios can be represented by a ratio of 4 : 5 ?

Answers

4 girls to 5 boys would be an appropriate scenario

There are  8 apples and 10 oranges in a basket.  In this scenario, we can see that ratio of apples to oranges is 4:5.

What is the ratio?

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

A ratio is a fraction that may compare part to whole or part to part. For example, suppose in a class, the ratio of boys to girls is 4 to 5. It means that the number of boys divided by the number of girls is a fraction that, in its simplest form, equals 4 over 5.

Same as there are 8 apples and 10 oranges in a basket. this is also represented perfectly in terms of ratio.

Therefore, In a basket, there are 10 oranges and 8 apples. We can observe that the ratio of apples to oranges in this situation is 4:5.

3. Which two integers are 7 units away from the number 5 on a number line?
A. -2 and 2
B. -2 and 7
C. -7 and 7
D. -2 and 12

Answers

Answer:

2B

3D

Step-by-step explanation:

2A is

a/b + -a/-b = a/b + a/b = 2a/b

this is NOT 0/0. you can't add numerator and denominator. when you have the same denominator, you can only add the numerator.

and don't forget : -×- and -/- are both + !

2B

you do not multiply anything. you ADD (but again NOT the denominators) !

and +×- or +/- = - !

overall this this adding a negative number to the same positive number. the result : always 0

2C

cannot be added like that. first you would have to bring both to a common denominator. but then you ADD !

2D

very similar to 2C.

5 + 7 = 12

5 - 6 = -2

these are the 2 integers 7 units away from 5.

The answer is C. -7 and -7

A truck drove 208 miles on 5 gallons of gas. How far should it be able to go on a full, 11-gallon tank?

Answers

Answer:

457.6

Step-by-step explanation:

if he drove 208 on 5 gallons, 208/5 =41.6 miles per gallon. 41.6*11= 457.6

Answer:

457.6 miles

Step-by-step explanation:

So 208 miles equals 5 gallons so if you add 208 two times you will already have used 10 gallons and that equals 416 miles so far. So now you have to divide 208 by 5 and that equals 41.6 so 416 plus 41.6 equals 457.6 miles

After 5 years, $40,000 deposited in a savings account with simple interest had earned $26,000 in interest. What was the interest rate?

Answers

Answer: The answer is 13% interest rate.

Step-by-step explanation: first divide the interest money by the number of years (or months it doesn't matter) which would get you 5200 then you would divide 5200 by the amount of money deposited into the bank (40,000) which should give you 0.13 or 13%

26,000 / 5 = 5,200

5,200 / 40,000 = 0.13 = 13%
