Answers

Answer:

x equals 14 - 7y

Step-by-step explanation:

x + 7y = 14

x = 14 - 7y

Then, we get x equals 14 - 7y.

Which of the expressions below is equal to 24/18? Select all that apply.Which of the expressions below is equal to 2418? Select all that apply.

Answers

Answer:

A, B, D

Step-by-step explanation:

Given that :

24 / 18 = 4 / 3 = 1.333

Comparing the options solutions for the options given :

3/9 ÷ 2/8 = 3/9 * 8/2 = 24 / 18 = 1.333

4/9 ÷ 2/6 = 4/9 * 6/2 = 24/18 = 1.333

5/6 ÷ 3/4 = 5/6 * 4/3 = 20 / 18

8/3 ÷ 6/3 = 8/3 * 3/6 = 24 / 18 = 1.333

Hence, expressions which are equal are :

A, B and D

The train is travelling with the speed of 90km/hr. What is the distance covered in 2min?​

Answers

We are given:

Speed of the train = 90 km/h

Converting the speed to km per minute:

[tex]90\frac{km}{h}* \frac{h}{60 min}[/tex]           [since 1 hour = 60 minutes, h/60 minutes is equal to 1]

The 'h' in numerator and denominator will cancel out

90km / 60 min

1.5 km/min

Distance travelled in 2 minutes:

Distance = Speed * time

Distance = [tex]1.5\frac{km}{min}* 2 min[/tex]

Distance = 3 km

PLEASE HELP!! A fair coin is flipped 3 times. What is the probability of the coin landing on heads 3 times? Why is that?

Answers

Answer:

If the coin is fair, then the odds of getting heads or tails should be equal, 12. Then 3 tosses of tails will have a chance of 12⋅12⋅12=18.

Answer:

1/8 or 12.5%

Step-by-step explanation:

The odds of getting heads is 50% (1/2) each time.

So putting the odds to the power of three will provide the odds of getting heads 3 times.

1/2 * 1/2 * 1/2 = 1/8 or 12.5%

Can anyone help ? I’m bad at math

Answers

Answer:

Step-by-step explanation:

First you need the third angle (C).

<C + 89  + 45 = 180       All triangles = 180 degrees. Combine the left terms.

<C + 134 = 180               Subtract 134 from both sides

<C = 180 - 134

<C = 46

Next, Let BA = x

x/Sin(46) = 15/Sin(89)

x = 15*sin(46) / Sin(89)

Sin(46) = 0.7193

Sin(89) = 0.9998

x = 0.7193 * 15 / 0.9998

x = 10.7911

Note

When you are studying this material, you should note 2 things.

The first is that you are dealing with 2 ratios that are equal to each other.The second is, the side is always opposite the angle in the triangle. The two are connect. Side c = 15. It is opposite the 89o angle.
