The y-intercept (where x = 0) of the equation is at -20.

For every 60 the x runs, the y falls by -10. Use rise over run to determine the slope of the equation.

$\frac{-10}{60} = - \frac{1}{6}$

Slope-intercept form is determined by the following equation:

$y = mx + b$

m is your slope, and b is your y-intercept.

Plug the slope and y-intercept into the equation.

$y = -\frac{1}{6}x - 20$

At time t=0 a woman tosses an apple straight up into the air. At time t= 0.5, it begins to fall back to her hand. She catches th

Shtirlitz [24]

The graph that could represent the motion of the apple is graph B.

<h3>What is a graph?</h3>

A graph is a diagram showing the relation between variable quantities, typically of two variables, each measured along with one of a pair of axes at right angles.

Here, the speed of apple at time t is given by v=0 + at which is a straight line of slope a that passes through origin because constant is zero. At time t=0 its initial speed is 0 and it will increase constantly with time. Therefore, graph (B) is correct

A pitcher can hold 5. 2 liters of water. How many 0. 4 liter glasses of water can be poured from the pitcher?

gogolik [260]

The number of 0.4 liter glasses of water that will be poured in the pitcher is 13

From the information given, we are being told that a pitcher can hold a maximum amount of 5.2 liters of water.

If we are to use a 0.4 liter of glass to pour water in the pitcher, then the number of times we will use the glass to pour water in the pitcher can be estimated as:

Number of glass that can fill the pitcher = 5.2 liters/ 0.4 liters

= 13 glass

By selling 20 oranges for#1.35 a trader makes a profit of 8% what is the percentage gain or loss if he sells the same 20 oranges

pav-90 [236]

Answer:

12% loss

Step-by-step explanation:

The selling price is the sum of the cost price and the markup. Here, the markup (profit) is expressed as a percentage of the cost price.

<h3>Cost price</h3>

The relation between selling price and cost price is ...

selling price = cost price + cost price × markup fraction

selling price = cost price × (1 + markup fraction)

Then the original cost price is ...

cost price = (selling price) / (1 + markup fraction)

cost price = #1.35 / (1 +8%) = #1.25

<h3>Profit</h3>

After the change in selling price, we can find the markup fraction (profit rate) to be ...

1 + markup fraction = (selling price)/(cost price)

markup fraction = (selling price)/(cost price) -1

markup fraction = #1.10/1.25 -1 = 0.88 -1 = -0.12

The trader has a 12% loss when selling the oranges at #1.10.

The graph shows the relationship between time and the number of soda bottles a machine can make. Use the points (4,112) and

Jlenok [28]

Using y to represent number of bottles filled in x minutes, y = 250x.

This is rather basic, and I urge you to think about it so that it's very clear to you, and you will be able to do similar problems on your own in the future.

The graph will be a straight line passing through the origin (0,0).
