Answer:
Number one the base is 24 and the Volume is 120
Number two the base is also 24 and the Volume is 240.
Step-by-step explanation:
For #1:
For the first one the area of the base is 8x3 which equals 24 so for base Number 1 its 24.
All we got to do to figure out the volume is multiply by 10 *the height* and then divide by 2 because we are finding the volume of a pyramid. 24x10 = 240/2 = 120. So the volume for Number 1 is 120.
For #2:
It has the exact same number except we are dealing with a rectangular prism which means at the end we don't have to divide by 2. For the base its 8 x 3 = 24 the same as the pyramid. For the volume- 8 x 3 = 24 x 10 = 240 which means the volume is 240. And of course don't forget the unit yards³

Answer: x = 1
Step-by-step explanation:
substitute 1 for x
1/2(10(1)+6) = -2(1)+10
1/2(10+6) = -2+10
5+3 = -2+10
8=8
Answer:

The value of the angles should be. (x-40°). , (x-20°), (½x-10°) , not (x-40°) + (x-20°)+(½x-10°)
Sum of all the interior angles of a triangle is 180°.
So a equation can be made by the given data,
(x-40°) + (x-20°) + (½ x-10°) = 180°
x-40°+x-20°+½x-10° = 180°
2x+½x -60°-10° = 180°
5/2 x - 70° = 180°
5/2 x = 180° + 70°
5/2 x = 250°
x = 250° × 2/5
x = 50° × 2
x = 100°
So the angles are
x-40° = 100°-40° = 60°
x-20° = 100°–20° = 80°
½x-10° = ½(100)° - 10° = 50° -10° = 40°
The answer can be checked by putting the values of the angle we got in the second statement i.e. Sum of all the interior angles of a triangle is 180°.
60° + 80° + 40° = 100° + 80° = 180°
