The ratio of boys to girls in the ninth grade is 6:5. If there are 185 girls in the class, how many boys are there.

Answers

Answer 1

Answer: There is 222 boys and 185 girls

Answer 2

Answer: There are 222 boys in the class. You find this by dividing 185 by 5 which gets you 37, so you have to multiply the 6 by 37 to find the amount of boys.

Answer:

4/5

Step-by-step explanation:

{(2/5) / (1/2)} ×1

= (2/5)÷(1/2)

= 2/5×2/1

= 4/5

Answer:

4/5

Step-by-step explanation:

Because if it can eat 2/5's in 1/2 hours, then if it eats for 1 whole hour or 2/2's it will be able to eat 4/5's of it's own body weight.

Just imagine that one half hour is 1 and if you add two half hours together it makes one complete hour or 2/2. So just multiply it by 2 cause it was eating for two half hours.

$(2)/(5) * 1=2/5\n(2)/(5) *2=4/5$

A particle moves along the x-axis so that at any time t, measured in seconds, its position is given by s(t) = 4sin(t) - cos(2t), measured in feet. What is the acceleration of the particle at time t = 0 seconds?

Answers

Answer:

The acceleration of the particle at time t = 0 seconds is:

4 feet per square second.

i.e. 4 ft/s²

Step-by-step explanation:

We are given a position function in terms of the time t as:

$s(t)=4\sin (t)-\cos (2t)$

Now, we are asked to find the acceeleration of the particle at time t = 0 seconds.

We know that the acceleration of a particle is given by:

$a=(d)/(dt)v$

where v is the velocity of the particle which is calculated by:

$v=(d)/(dt)s$

Hence, we get:

$a=(d)/(dt)((d)/(dt)s)\n\ni.e.\n\na=(d^2)/(dt^2)s\n\ni.e.\n\na=s''(t)$

i.e. the acceleration of the particle is the double derivative of the position.

$s'(t)=4\cos (t)+2\sin (2t)$

and

$s''(t)=-4\sin (t)+4\cos (2t)$

i.e.

$a(t)=-4\sin (t)+4\cos (2t)\n\ni.e.\ at\ t=0\ we\ have:\n\na(0)=-4\sin 0+4\cos 0\n\ni.e.\n\na(0)=4$

B. 8x- 2y -2z
C. 8x- 14y- 2z
D.8x -2y -3z

Answers

I believe the answer is B.
5+3=8
therefore being 8x
6-8=-2
therefore being -2y
-3+1=-2
there for being -2z
8x-2y-2z

hope this helps

so im trying to help my little brother with his home work an i suck at math so can anyone tell me what 5/9X54

Answers

First do 5 divided by 9. Then 0.56 times 54. Your answer is 30. Have a great day!

So, in this problem, its basically multiplying a whole number with a fraction. So what you do is.... multiply 54 by 5 and you get 120. Then, you do 54 multiplied by 9 and get 486. Then, you will have 120/486! That will be your answer to this problem.
