Step-by-step explanation:
The opposite angles of an inscribed quadrilateral are supplementary, thus
5x + 20 + 7x - 8 = 180
12x + 12 = 180 ( subtract 12 from both sides )
12x = 168 ( divide both sides by 12 )
x = 14
Thus
∠ RQP = 10x = 10(14) = 140°
∠PSR = 180° - 140° = 40° ( opposite angles are supplementary )
∠ SRQ = 7X - 8 = 7(14) - 8 = 98 - 8 = 90°
∠ QPS = 5x + 20 = 5(14) + 20 = 70 + 20 = 90°
Answer:
1.4
Step-by-step explanation:
This is because the 4 is in the hundreds place but the 0 is in the hundreds in the second one.
(Decimals are backwards from whole numbers.)

Answer:
D. 2.33.
Step-by-step explanation:
Given;
the weight distribution of the bottles = 4, 2, 5, 4, 5, 2, and 6
sum of the weights = 28
the mean (x) = 28/7
x = 4
the sum of square of the mean deviation is calculated as:
= (4 - 4)² + (2 - 4)² + (5 - 4)² + (4 - 4)² + (5 - 4)² + (2 - 4)² + (6 - 4)²
= 0 + 4 + 1 + 0 + 1 + 4 + 4
= 14
Therefore, the correct answer is D
Answer:
10
Step-by-step explanation:
Let us find the exact number of donors of gold and bronze respectively given there are 40 in total.
Gold: 45% of 40 = 45/100 *40 = 18 donors
Bronze: 20% of 40 = 20/100 *40 = 8 donors
18 donors - 8 donors = 10 more donors
