Answer:
5
Step-by-step explanation:
Salma and Jared each threw 5 darts at the target shown. Salma scored 19 points by landing 2 darts in A and 3 in B. Jared scored 17 points by landing 1 dart in A and 4 in B. How many points are given for a dart landing in A?
this can be solved using simultaneous equation. Two equations can be formed from the question
2a + 3b = 19 equation 1
1a + 4b = 17 equation 2
Multiply equation 2 by 2
2a + 8b = 34 equation 3
Subtract equation 1 from 3
5b = 15
divide both sides of the equation by 5
b = 3
Substitute for b in equation 1
2a + 3(3) = 19
2a = 9 = 19
collect like terms
2a = 10
divide both sides of the equation by 2
a = 5
Answer:
251.33 = 251
Step-by-step explanation:
V= πr²h = π·2²·20 ≈ 251.32741 = 251.33
Answer:
x = 33.8°
Step-by-step explanation:
The resulting diagram we have is a right triangle. To find x, apply trigonometric function.
Reference angle = x
Opposite = 116
Adjacent = 173
Apply TOA:
Tan x = Opp/Adj
x = 33.8° (nearest tenth)
