X + 3x = 12

(Or 4x=12)

the first x is the number of girls then the second x is the girls times 3, which is how many boys there are.

A prism is filled with 70 cubes with a side length of 1 2 unit. What is the volume of the prism in cubic units? Enter answer as

galina1969 [7]

Answer:

The volume of the cube is;

$8\dfrac{3}{4} \ cube \, units$

Step-by-step explanation:

The parameters of the prism are;

The number of cubes used to fill the prism, n = 70 cubes

The side length of each cube, s = 1/2 unit

The volume of the cube, V = n × s³

∴ Therefore, the volume of the cube, V = 70 × (1/2)³ = $8\dfrac{3}{4} \ cube \, units$ = 8.75 cube unit

Determine the value of w and x in the figure below. (Thanks for the help I really appreciate it!)

storchak [24]

Triangle HAM looks like an isosceles triangle, and we know that in an isosceles triangle 2 of the angles are the same.

so :
180 - 106 = 74 ( sum of the other 2 angles )
74/2 = 37 ( sum of angle HMA / HAM )

angles on a straight line add up to 180.
180-37=143 ( angle x )

since triangle YMH is also an isosceles,
180-37=143
143/2=71.5 ( angle w )
