What is the y-intercept of the function described by the data in the table below? Xy -1 5 2 -7 5 -19

Answer:

the unit price on is $2.50

Step-by-step explanation:

61.5÷24.60

Assuming Ryan buys 61.5 ounces of lemonade for $24.60. The unit price is: $0.4.

Using this formula

Unit pice=Cost price/ Ounces of lemonade

Where:

Cost price=$24.60

Ounces of lemonade=6.15 ounces

Let plug in the formula

Unit price=$24.60/6.15

Unit price=$0.4

Therefore the unit price is: $0.4.

Answer:

x=35

Step-by-step explanation:

you are going to want to subtract. the best thing about triangle angles is that they all add to equal 180º no matter what. so what you can do is subtract the given angles from 180. so 180-80-65. which gives us 35.

Hope this helps!

Answer:

I believe you add, degrees in triangles are 180 so 80+65= 145. 180-145 is 35

F → (2, -2)

E → (0, 5)

Step-by-step explanation:

Coordinates of a point is given by [tex](x,y)[/tex].

Here, [tex]x[/tex] represents the horizontal distance of the point from origin [tex](0,0)[/tex] and [tex]y[/tex] represents the vertical distance of the point from origin.

Let's take an example of point D,

Horizontal distance of point D from origin [tex]x=-3[/tex] and vertical distance from origin [tex]y=3[/tex]

Coordinates of the point D will be (-3, 3).

Coordinates of the point F will be (2, -2).

Coordinates of the point E will be (0, 5).

Answer:

700

Step-by-step explanation:

price x .80 (100%-20)=560

price=560/.8

price=700

The item's initial cost before taxes is $700.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, A sales item is 20% off. If the final price of the item was $560.00

Let "x" be the original price of the item

Since If the final price of the item was $560.00

Thus,

x(1 - 20%) = 560

x(1- 20/100) = 560

x(80/100) = 560

x = 700

therefore, The original price of the item without tax will be $700.

Answer: 38

Solution: An isosceles triangle has two equal sides: 3x - 5 and 19-x.; 3x - 5 = 19 - x; 4x = 24; x = 6

Let's check it out: 3(6) - 5 = 13; 19 - (6) = 13; 2(6) = 12

Two equal sides are 13 and base 12

Perimeter is 13 + 13 + 12 = 38 units

Answer is: 38

The perimeter of the given isosceles triangle is 38 cm.

The perimeter of an isosceles triangle refers to the addition of all the three sides of the triangle. Since the base angles of an isosceles triangle have two angles and two sides equal;

We can say that the perimeter of an isosceles triangle is:

P = 2a + b

where;

3x - 5 =  19 - x

3x + x = 19 + 5

4x = 24

x = 24/4

x = 6

The perimeter of the isosceles triangle is:

= 3x - 5 + 19 - x + 2x

= 3(6) - 5 + 19 - 6 + 2(6)

= 18 + 8 + 12

= 38 cm

Step-by-step explanation:

Not adding or multiplying

Answer:

The perimeter of the figure is approximately 42.85.

Step-by-step explanation:

Based on the given values, you already know that two of the sides of the shape are 12 units long. Since the half-circle above the rectangle is the same size as the gap in the rectangle - you know this because both of the half-circle's diameter are 6 units long - so you can add 24 units to the perimeter of a circle with a diameter of 6. The diameter of the circle is [tex]6\pi[/tex], or approximately 18.85, so the perimeter of the whole figure is approximately 42.85.

Answer:

Part A

The motion of an elevator in a building is mechanically controlled by electrical powered devices and therefore, the motion of an elevator between start and stop is uniform motion without acceleration and therefore, a person in a moving elevator will not experience a force, therefore a blindfolded person will believe that the elevator is not moving at all

Part B

Yes the person can tell when the elevator begins or stops

When the elevator begins moving, the velocity increases from zero at a rate and the blindfolded person will be able to sense the ground moving further lower under their feet making them feel lighter

Similarly, when the elevator slows down to stop, the initial downward velocity of the elevator is steadily reduced as the elevator decelerates. The blindfolded person will be able to sense the slowing down (braking) of the elevator experiencing an increased upward force from the floor of the elevator, with the feeling of slightly increased weight
