Answer:
C
Step-by-step explanation:
according to sine rule,
sin(30)/8=sin(x)/11
solving above equation will give
x=43.3
Answer: the cyclist must wait for 25 minutes until the hiker catches up.
Step-by-step explanation:
Distance = speed × time
The Cyclist was travelling in the same direction along the same path
as the hiker at a constant rate of 20 miles per hour. If the cyclist stops to wait for the hiker 5 minutes after passing her, then the distance that the cyclist travelled in 5 minutes(5/60 hour) is
20 × 5/60 = 100/60 miles
For the hiker to catch up with the cyclist, she would cover 100/60 miles at a speed of 4 miles per hour.
Time = distance/speed
Time required by hiker to catch up with the cyclist is
(100/60)/4 = 100/240 hour
Converting 100/240 hour to minutes, it becomes
100/240 × 60 = 25 minutes
Answer: 6 tsp of baking powder.

Answer:
13,680millimetres of water are blown
Step-by-step explanation:
1/100litre of water is equaled to 10 millilitres
:• 4/100 litres= 40millilitres
they are 342 guests if each guest blows a bottle of bubble containing 40millilitres the to get the total of milliliters blown u gotta multiply the amount of guest by the total millitres for one bottle to set down u will put
342 guests × 40 millitres= (13680) amount of bubble blown
Answer:
10 In.²
Step-by-step explanation:
Formula for height of trapezoid: 2a ÷ (b1 + b2)
B1: 3, B2: 7
Area: 50
7 + 3 = 10
50 · 2 = 100
100 ÷ 10 = 10
Height of trapezoid: 10 In.²
Check:
Formula for area of trapezoid (using height): A = (B1 + B2 / 2) · h
Base1: 3, Base2: 7
7 + 3 = 10
10 ÷ 2 = 5
5 · 10 = 50
Area = 50, therefore we know that our height is correct.
