Answer:

Step-by-step explanation:

Take any 2 points on the graph,

(50, 10) & (90, 90)

Use the slope formula:

$\frac{y2-y1}{x2-x1}$

= (90-10)/(90-50)

= (80)/(40)

= 2

Hence, the slope is 2.

Answer:

d. 84.5

Step-by-step explanation:

You will have to put the numbers in order than cross out one from each side;

70x

80x

88x

In doing this you have taken out B,E, and F. The answer would have to be somewhere in between 83 and 86, which would be around 84 and 85, so therefore the answer would be 84.5

The radius of a cylinder is doubled and its height is halved. Find the ratios of their surface areas.

Inessa [10]

Answer: 1:1

Step-by-step explanation:

Let r be the radius and h be the height of a cylinder.

Formula: Curved surface area of cylinder = $2\pi rh$

Now, if radius of a cylinder is doubled and its height is halved, then new radius will be R= 2r and new height will be $H=\dfrac{1}{2}$

Now, new surface area = $2\pi RH= 2\pi(2r)\dfrac{h}{2}= 2\pi rh$

Ratio of curved surface areas : $\dfrac{\text{Surface area}}{\text{New surface area}}=\dfrac{2\pi rh}{2\pi rh}=\dfrac{1}{1}$

Hence, the ratios of their surface areas = 1:1 .

A pearl is formed in 1 of every 10,000 oysters. What percent of oysters make pearls? Hint: An answer of 1, percent would mean 1

zysi [14]

It would be 0.001 because if 1 is for 100 oysters, then you would add two zero's in front and move the decimal point over twice, therefore you get 0.001% as your answer.
