A piece of cable 8.5 cm long weighs 52 grams. How much does a cable that is 10 cm long weigh

8.5 cm cable weighs = 52 grams

1 cm of cable weighs = $\frac{52}{8.5}grams$

  = $52/ \frac{85}{10}$ grams
= $52* \frac{10}{85}$ grams
= $\frac{520}{85}$ grams
= $6.11764$ grams
Rounding it up = 6. 10000 grams

Then,

10 cm of cable weighs = $6.10*10$ grams
   <span>   </span>= $61.0$ grams

Find the point-slope equation for the line that passes through the points (5, 19) and (-5, -1). Use the first point in your equa

antiseptic1488 [7]

Answer:

$m = \frac{y_ 2 -y_ 1}{x_ 2 -x_ 1 } \\ = \frac{ - 1 - 19}{ - 5 - 5} = \frac{ - 2 0 }{ - 10} \\ \therefore \: m = 2 \\ y + 1 = 2(x + 5)$

What is the surface area of the right cone below? Help ASAP please

mezya [45]

For this case we have that by definition, the surface area of a cone is given by:

$SA = \pi * r * s + \pi * r ^ 2$

Where:

r: It is the cone radius

s: It's the slant height

According to the data we have: $s = 14\\r = 8$

Substituting:

$SA = \pi * 8 * 14 + \pi * (8) ^ 2\\SA = \pi * 112 + \pi * 64\\SA = 176 \pi$

Thus, the surface area of the cone is $176 \pi \ units ^ 2$
