Answer:

see below

Step-by-step explanation:

Let h = hours worked

d = dollars earned

d = 4h

d     h

----------

0      0

4      1

 8     2

 12     3

 16     4

The relationship is proportional.  It goes through (0,0) and the slope is constant.

x = amount of hours

y = amount of money earned

Equation: 4y = x

Lets solve for the first few coordinates:

(0, 0)

(4, 1)

(8, 2)

(12, 3)

(16, 4)

(20, 5)

Since 4 is the amount earned per hour, that is going to be the slope. Since she has no starting fee, the y-intercept is 0.

Best of Luck!

The graph shows the distance traveled by an Olympic-level sprinter over time during a race.
Svet_ta [14]

Answer:

the slope is 1

Step-by-step explanation:

if you start at (0,0) and go up one and then right on the line lines up with the squares so since slope is  \frac{rise}{run} you go up one and the right one which makes it \frac{1}{1} so the answer is one.

(-1,-2) and (3,10)?<br> what’s the equation
Ahat [919]

Answer:

Step-by-step explanation:

If we have two coordinates on a line (x1,y1 =1,2) and (x2, y2 =3,6) we can solve for m as follows. (x2,y2) 6=m3+c - (x1,y1) 2=m1+c

A can in the shape of a cylinder has a diameter of 10 cm and a height of 6 cm. how much wrapping paper is needed to cover the cy
Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

To determine the amount of wrapping paper needed to cover the can, we would determine the total surface area of the cylindrical can. The formula for determining the total surface area of a cylinder is expressed as

Total surface area = 2πr² + 2πrh

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

From the information given,

Diameter = 10 cm

Radius = diameter/2 = 10/2

Radius = 5 cm

Height = 6 cm

Therefore,

Total surface area = (2 × 3.14 × 5²) + (2 × 3.14 × 5 × 6)

= 157 + 188.4 = 345.4 cm²

345 cm² of wrapping paper is needed to cover the cylinder.

2) Volume of cylinder = πr²h

Volume of cone = 1/3πr²h

3 × Volume of cone = πr²h

The volume of the cylinder is 3 times greater than the volume of the cone. Therefore, the volume of the cone is 1/3 times lesser than the volume if the cylinder.

Can someone please help mee
cricket20 [7]

Answer:

5/13

Step-by-step explanation:

sine=opposite/hypotenuse

cosine=adjacent/hypotenuse

opposite=-12 (I know that this is not possible)

hypotenuse=13

These are ratios, not real lengths

using the Pythagorean theorem, the other leg is 5

cos (theta)=5/13

Ahat [919]

Given:

A person leaves work and travels west for 15 miles.

They then turn left and travel south for 10 miles, to their home.

To find:

Distance between work place and home.

Solution:

The person travels west for 15 miles, then travel south for 10 miles.

It means, it forms a right angle triangle with legs 15 and 10.

To find the distance between work place and home we need to find the hypotenuse of the triangle.

Pythagoras theorem:

Hypotenuse^2=Base^2+Perpendicualr^2

(OB)^2=(15)^2+(10)^2

(OB)^2=225+100

(OB)^2=325

Taking square root on both sides.

OB=\sqrt{325}

OB=\approx 18.03

Therefore, the bird would fly 18.03 miles.
