Answer:
∠ B = 19°
Step-by-step explanation:
note ∠ C = 90° ( angle in a semi- circle )
The sum of the 3 angles in the triangle = 180°, thus
∠ B = 180° - (90 + 71)° = 180° - 161° = 19°
Answer:
B) 1 7/8
Step-by-step explanation:
1. first, if you have 16/8 then it would be 2, but since it is 15/8 you need to minus 15 and 8
2. 15-8=7, now you only have 7
3. last, since you only have 7 then it is 1 whole and 7 8ths
4. 1 7/8 is your answer.

Step-by-step explanation:
(a)
The shaded figure is a trapezium with area (A)
A = 0.5 h(a + b)
where h is the perpendicular height and a, b the parallel sides, thus
A = 0.5 × 10 × (8 + 14) = 5 × 22 = 110 cm²
(b)
The volume (V) of the prism is calculated as
V = area of end face × depth
= 110 × 3 = 330 cm³
Answer:
7 9/14
Step-by-step explanation:
The girls ate 8 1/7 of a pie, so we mark G=8 1/7
The boys ate 1/2 of a pie, so we mark B=1/2
The girls ate the more pies, so we do this:
G-B
We plug the G and the B in, and it is 8 1/7-1/2
We change it to the common denominator, which is 14. We have 8 2/14- 7/14
we take a one and add 14 to 2 and we have this:
7 16/14-7/14
and that equals 7 9/14
