Answer:

Option A: y-9=2(x-1)

Step-by-step explanation:

Notice that the answer choices are in point-slope form which is y-y1=m(x-x1)

The slope, m, is (9-3)/(1-(-2))=6/(1+2)=6/3=2, but that's given anyway.

Option A would be right because y1=9 and x1=1 which is where the line crosses through (1,9)

B is not right because that would suggest the line crosses (2,3) as y1=3 and x1=2, but it actually crosses (-2,3) so it should've been y-3=2(x+2)

C and D are wrong because the points aren't crossed through

2. An articulated truck is loaded with cylindrical containers filled with oil. The height of each container is 80cm and the diam

RoseWind [281]

The volume of each container is: 25,133 $cm^{3}$

Given:

height of container (h) = 80 cm

diameter of container (d) = 20 cm

radius = half of diameter = $\frac{1}{2}$ of $20 = 10 cm$

Recall:

Volume of a cylinder = $\pi r^{2} h$

<em>Substitute the values into the formula:</em>

$Volume = \pi \times 10^{2} \times 80 = 25132.74123$

Therefore, volume of each cylinder is approximately 25,133 $cm^{3}$

There are 312 cards in 6 deck of playing cards write the ratio as a fraction them find the unit rate

ladessa [460]

Answer:

6x: 312

x: 52

Step-by-step explanation:

Let the deck be denoted by x then

6x: 312

There are 312 cards in 6x decks

In 1 deck x there are 312/6= 52 cards

6x: 312

6x/6: 312/6 Cancelling both sides by 6

x: 52

In ratio both the sides are divided by the same number to get equivalent fractions.

In 1 deck there are 52 cards
