HELPPPPPP PLEASe!!!!!!!!

First, put it into slope/intercept form so you can see what you've got.

"Slope/intercept form" is  y = everything else .

So that means you have to take the equation you have and "solve it for 'y' ".

2y - 10x = 20

Add 10x to each side: 2y = 10x + 20

Divide each side by 2 :  y = 5x + 10

There it is.
Now that you have it in that form, you can just look at it and see that the
slope of the line on the graph is 5, and the line crosses the y-axis at 10.

And that's exactly the information you need to graph it. On your graph,
mark a little dot on the y-axis at 10, and draw a line through that dot
with a slope of 5.

a net force of 100 Newton's is applied to a 20-kilogram cart that is already moving at 3 meters per second. The final speed of t

sergeinik [125]

Answer:

The Force is applied for 1 sec

Step-by-step explanation:

Given as :

The Total force applied on cart = 100 Newton

The mass of cart = 20 kg

The initial velocity of cart ( v1) = 3 meter per second

The final velocity of cart (v2) = 8 meter per second

∵ Force = mass × acceleration

Or, 100 N = 20 kg × acceleration

Or, Acceleration = $\frac{100}{20}$

Or, Acceleration = 5 Newton per kg

Again ∵ Acceleration = Rate of change of velocity

I.e Acceleration = $\frac{v2 - v1}{t}$

Or, 5 Newton per kg = $\frac{8 -3 }{t}$

Or, Time = $\frac{5}{5}$ = 1 sec

Hence The Force is applied for 1 sec Answer

Someone please help! i don’t get what it’s asking or how to do it :( worth 12 points

Answer:

2 cubic yards

Step-by-step explanation:

In this problem we are simply finding the volume of a 3D shape. We can calculate this by L × W × H.

9.5 × 12 × 1/3 = 48 ft³

(Note: 4 inches is 1/3 foot)

This means Rosilaine needs 48 cubic feet of wood chips. However, the wood chips are sold in yards, so we need to convert cubic feet to cubic yards.

48 ÷ 27 = 1.777 (repeating decimal)

This means Rosilaine should buy 2 cubic yards of wood chips.

The volume of oil in four different containers is shown below:

adell [148]

Answer:

Container A: 5.35 milliliters rounds up to 5.4.

Step-by-step explanation:

Because she can measure to the nearest .1, we round. Numbers over .05 get rounded up, and below .05 get rounded down.

Container A: 5.35 milliliters rounds up to 5.4

Container B: 5.25 milliliters rounds up to 5.3

Container C: 5.29 milliliters rounds up to 5.3

Container D: 5.32 milliliters rounds down to 5.3

Answer:

$125
$65, $65, $65 -- they are all the same

Step-by-step explanation:

The quantity of food required for the two cats for one day is ...

(3/4 can) + (1/2 can) = (3/4 +2/4) can = 5/4 can

Then the cost per day for cat food is ...

$5/(3 cans) × (5/4 can/day) = $25/12 /day

We note that the cost for some number of days will be the product of this factor and the number of days, rounded up to the next higher $5.

1. The cost for 60 days is ...

(60 days)($25/12 /day) = $25 × 60/12 = $125

A 60-day supply of cat food costs $125.

__

2. A 29-day supply costs ...

(29 day) × $25/12 /day = $60 5/12, rounds up to $65 for 29 days

A 30-day supply costs ...

(30 day) × ($25/12 /day) = $62.50, rounds up to $65 for 30 days

A 31-day supply costs ...

(31 days) × ($25/12 /day) = $64 7/12, rounds up to $65 for 31 days.

These costs are all the same.

_____

3 cans last, on average, 2 2/5 days. That means some purchases of 3 cans will last for 2 days, and some will last for 3 days. It so happens that the purchase made to cover day 29 will also cover day 30 and day 31.
