P = m/v
To find the mass you have to do Density x Volume.
The volume of the cuboid is 0.18 m cubed and the density is 2.7g/cm cubed.
The 2.7 g/cm cubed must be converted into kg/m cubed to find the mass in kg. Which is 2,700 kg/ m cubed.
2,700 x 0.18 = 486 kg.
The mass of the marble in kg is 486kg
<span>2 and 3/4 punds of roast beef 2 3/4 = (4x2) + 3 /4= 11/4 roast beef

33/16 salami divided <span> 1/4 = 33/16 x 4 = 33/ 4 = 8 sandwiches</span>
Answer:
B
Step-by-step explanation:
Since the triangle is right use Pythagoras' identity to solve for BC
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
BC² = AB² + AC² ← substitute values
BC² = 18² + 80² = 324 + 6400 = 6724 ( take the square root of both sides )
BC =
= 82 → B
Given:
Triangle QRS has coordinates Q(-2, -2), R(0, 3), and S(4, -2) and is dilated by a scale factor of 2.
To find:
The new coordinates of point S', and state whether the dilation is an enlargement or a reduction.
Solution:
If a figure is dilated by factor k with origin as center of dilation, then

Where, 0<k<1 is reduction and k>1 is enlargement.
The figure is dilated by scale factor 2 which is greater than 1, so the dilation is an enlargement. The rule of dilation is:

Using this rule, we get


Therefore, the new coordinates of point S' are (8,-4).
