Answer:I believe the answer is the last one d

Step-by-step explanation:

Have I got my answer to this is that I figured out how many fours were on our side was there for four so that equals 16 and then I figured out how many threes or worse that there is for threes which would equal to two sixes and then to six ended up with an equal up to 12 and such as the fours I did 4+4 is eight and then 8+8 is 1216 so the simplest form you can put in it is 16+12 and that’s how they got my answer

in an election an amount of votes was share among parties A,B and C in the ratio of 1:2:4. How many votes party B obtained if pa

spayn [35]

1000

Step-by-step explanation:

Let the share of votes obtained by the parties A, B and C be x, 2x and 4x respectively.

According to the given information:

No of votes obtained by C = 1500 + No of votes obtained by A

$\therefore 4x = 150. + x \\\\\therefore 4x - x = 1500\\\\\therefore 3x = 1500\\\\\therefore x = \frac{1500}{3} \\\\\therefore x = 500\\\\\because Votes \:obtained\: by \:B = 2x \\\\\therefore Votes \:obtained\: by \:B = 2\times 500\\\\\purple {\bold {\therefore Votes \:obtained\: by \:B = 1000}} \\\\$

10.) Kelly is flying a kite to which the angle of elevation is

jarptica [38.1K]

Answer:

61.08m

Step-by-step explanation:

Let " l " be the length of the rope and " θ " the angle at which it is raised. In other words:

l = 65m
θ = 70°

As you can see, there has been made a right angle triangle. So:

$sin70 = \frac{h}{l} \\ h = l \times sin70 \\ h = 65 \times 0.9397 = 61.08 \\ h = 61.08$

So the kite is approximately 61.08m above the ground.

In order to find the sin70° i used a calculator.
