1 answer:
Kamila [148]3 years ago
7 0

Answer:

x = 3

Step-by-step explanation:

\sin \: 45 \degree =  \frac{BC}{6 \sqrt{2} }  \\  \\  \frac{1}{ \sqrt{2} } =  \frac{BC}{6 \sqrt{2} }  \\  \\ BC = 6 \\  \\  \cos \: 60 \degree =  \frac{x}{BC }  \\  \\   \frac{1}{2}  =  \frac{x}{6 }   \\  \\ x =  \frac{6}{2}  \\  \\ x = 3

The height, h, of a plant (in inches) w weeks since it was planted is represented by the equations h=3w+3. How many weeks will i
Hatshy [7]

Answer: 3 weeks

Step-by-step explanation:

We have to note firstly that 12 inches = 1 foot.

The equation given to represent the height in the question, h = 3w + 3.

The number of weeks that it will take the plant to reach one foot will then be:

h = 3w + 3

12 = 3w + 3

3w = 12 - 3

3w = 9

w = 9/3

w = 3

It'll take 3 weeks

Hunter-Best [27]

Answer:

9000 - 500m

Step-by-step explanation:

Your original number is 9000. It starts to decrease at a rate of 500 feet per minute. So we know that you will subtract 500 from 9000 but we don't know how many times. Because of this, we will put a variable to represent the minutes that we are descending.

In conclusion: 9000 - 500m

elena-14-01-66 [18.8K]

Answer:

<em>AD is 6.5 units</em>

Step-by-step explanation:

Find the diagram attached.

From the diagram, you can see that the dotted triangle is a right angled triangle with side AD as the hypotenuse.

To get AD, we will use the pythagoras theorem as shown;

Hyp² = Opp² + Adj²

AD² = 6²+2.5²

AD² = 36 + 6.25

AD² = 42.25

AD = √42.25

<em>AD = 6.5</em>

<em>Hence the measure of length segment AD is 6.5 units</em>
