Answer: 16.26 g.

To answer this question, you just need to multiply the volume with the density. In most question, the unit of the volume and density is different thus need to be converted. But in this question, it's already same so you can do it straight away. The calculation would be:

Mass: 6 cm3 x 2.76g/cm3= 16.26 g.

Anna [14]

Answer:

c = 58x

Step-by-step explanation:

A linear equation is an equation in the form of f(x) = mx + c. Where m is the slope and c is the intercept.

Let the price of one guitar lessons be x, then 47guitars will be 47x and 11 guitar lessons will be 11x. All together will be 47x + 11x = 58x.

Thus, the total cost, c, is

c = 58x

The window in Mr. Rodriguez's attic is in two parts, each shaped like a trapezoid and each with identical dimensions.
MaRussiya [10]

Answer and Step-by-step explanation:

First, ~multiply~base~and~height.~In~our~case~the~base~is~30~inches~and the~height~is~12~inches.Then,~we 'll~take~16~inches~and~multiply~it~with~12~inches

<u><em>So, it'll be :</em></u>

<u><em></em></u>30~inches × 12~inches =360~inches

16~inches × 12~inches=192~inches

Now,~that~we've~got~ 360 ~and~ 192~ as~ our~ answers ~we ~add~ them ~up..

<u><em>Like this :</em></u>

<u><em /></u>360+192=552<u><em /></u>

<u><em /></u>

<u><em /></u>And,~that's~our~final~answer!-522~in^2<u><em /></u>

Whats the area of the lawn in this shape
Licemer1 [7]

Answer:

208 ft

Step-by-step explanation:

in order to do this we need to find the area of the retangle:

(l x w) 14x20= 280ft

then the area of the rectangle:

a^2 + b^2 = c^2 ( hypotenus lenght )

c= 8.5

now we can plug in to find the area of the triangle, which is 12 (11.99)

then the area of the trapezium= 60

finally we can find the answer

280 - (60+12)= 208 ft :)
