The answer to the first question
is 2 1/4.
The answer to the second question is 8 sqroot 3. Hope I was able to help
Answer:
Step-by-step explanation:
what is the value of a in a/5 + 3= 8
a/5 + 3= 8
a/5 = 8 - 3
a/5 = 5
a = 5 * 5
a = 25

Answer:
(c) BK = 65
Step-by-step explanation:
Corresponding sides are proportional in similar triangles, so ...
ZT/ZQ = KF/KB
27/(2x +7) = 45/(4x+1)
27(4x+1) = 45(2x +7) . . . cross-multiply
3(4x +1) = 5(2x +7) . . . . divide by 9
12x +3 = 10x +35 . . . . . eliminate parentheses
2x = 32 . . . . . . . . . . . . . subtract 10x+3
x = 16 . . . . . divide by 2
Then the length of BK is ...
BK = 4x+1 = 4·16 +1
BK = 65
Answer:
2x + y
Step-by-step explanation:
x² + xy - y² = 4
→ Remember the rule, bring the power down then minus 1
2x + y
Answer:
22.8 m/s at 17.4°
Step-by-step explanation:
Horizontal component:
vₓ = 3 + 20 cos 20° = 21.8
Vertical component:
vᵧ = 0 + 20 sin 20° = 6.84
Magnitude:
v² = vₓ² + vᵧ²
v² = (21.8)² + (6.84)²
v = 22.8 m/s
Direction:
θ = atan(vᵧ / vₓ)
θ = atan(6.84 / 21.8)
θ = 17.4°
