Answer 1

Answer:

y = √(3² + 3²)

9 = √(5² + x²)

Step-by-step explanation:

Diagram 1:

Hypotenuse = y

Opposite = 3

Adjacent = 3

y² = 3² + 3²

y = √(3² + 3²)

y = √(9 + 9)

y = √18

Diagram 2:

Hypotenuse ² = known leg² + unknown leg²

Hypotenuse = 9

Known leg = 5

Unknown leg = x

9² = 5² + x²

9 = √(5² + x²)

9² = 5² + x²

9² - 5² = x²

x² = 81 - 25

x = √ 56

. Bryon competes on the school debate team. He won 0.40 of the debates in which he participated. Which statement is not true about Byron's debates?

Answers

Answer: See explanation

Step-by-step explanation:

You didn't give the options but let me help out.

Since Bryon won 0.40 of his debate, this means that he won 40% of his debate. 40% converted to fraction equals 40/100 = 2/5.

Since he won 40%, it means that he lost (100% - 40%) = 60%. He lost 3/5 and won 2/5.

Answers

Answer:

rotation

Step-by-step explanation:

A rotation is a transformation in a plane that turns every point of a figure through a specified angle and direction about a fixed point. The fixed point is called the center of rotation. The amount of rotation is called the angle of rotation and it is measured in degrees.

Therefore, the fixed point is called the center of rotation.

What are the angles?

Angles are formed when two lines intersect at a point. The measure of the 'opening' between these two rays is called an 'angle'.

A rotation means that the transformation in a plane that turns every point of a figure through a specified angle and direction about a fixed point.

So,the fixed point is called the center of rotation. The amount of rotation is called the angle of rotation and it is measured in degrees.

Hence, the fixed point is called the center of rotation. The amount of rotation is called the angle of rotation and it is measured in degrees.

Ms. Fox loves to eat cereal and she notices that she only has 1/3 of the box of cereal left. If she spread that amount across 5 days, how much cereal will she have for each day?

Answers

Answer:

1/15

Step-by-step explanation:

Ms. Fox loves to eat cereal and she notices that she only has 1/3 of the box of cereal left. If she spread that amount across 5 days, how much cereal will she have for each day?

The amount of cereal she would have per day is calculated as:

5 days = 1/3 of the box

1 day = x

Cross Multiply

5 days × x = 1 day × 1/3 of the box

x = 1/3 ÷ 5

x = 1/3 × 1/5

x = 1/15 of the box

PLEASE HELP ASAP ILL GIVE YOU 30 POINTS Jamie is excited for spring break this year. Her family is planning a vacation! She fully intends to take 20 pictures each day. checking her phone before leaving she notices she has 75 pictures already on the phone.

Given that the vacation will last a full seven days and Jamie's phone can hold a total of 200 pictures. How many pictures will she need to delete an order to make enough room in her phone for vacation photos?

Answers

The answer is 15
Since 20 times 7 is 140 and 140+75 is 215
Take 215-200 you get 15

Answer:

15 photos

Step-by-step explanation:

one can start off by first seeing how many photos will be taken on the vacation. We can do that by multiplying the days with how many photos will be taken for each- so 20×7= 140. Then we can take the total amount of photos the phone cam hold-200 subtract what we already have 200-75= 125 thats how much space if left but we need more (140). So the. we can start making quick guesses by taking 5 from 75 and see what we get then taking another 5 and another if needed we get 60 that finally gives when subtracted from 200- 200-60=140 the amount of space we need. Then finally we can just do 75-60 to get the total amount of photos we must delete. 75-60= 15

y = (2)* + 50
y = 50x - 4
y = 50(1.4)*
y = 500.05)*
(The little star things are x in exponent form)

Answers

Y=50(1.4)*

Equations 1,3,4 are exponential (the 2nd isn’t so it’s out)

Y intercept means x is set at 0 so start testing
For y=2*+50 when x=0 y=1+50=51
(Any number raised to a 0 exponent is 1)
For y=50(1.4)* y=50(1) so y=50 and that is what you are looking for

At a sale this week, a desk is being sold for $133 . This is 35% of the original price.
What is the original price?

Answers

Answer:

392.35

Step-by-step explanation:

35% + 35% is 70 % so 133 +133 is 70 % witch is 269.

next we need to figure out 30 percent and they give us 35 % so. you add to zeros to 30 because percentage is out of 100 and there are 2 zeros in 100. so it look like this

3000 ÷ 133 = 22.56 is 30% of 133

70% + 30% = 100%

269 + 22.56= 291.56 is your answer
