Answer:

11 and -11

Step-by-step explanation:

This problem can really only be solved either by way of a calculator or simple memorization. In this case, the product (121) is a perfect square root, meaning it has a whole number answer. One square root of 121 is 11. The second square root of 121 is -11.

\sqrt{121} = 11

\sqrt{121} = -11

You can check your work by squaring your answer and seeing whether it equals the product. Remember, a negative number times another negative number results in a positive answer.

11^{2} = 121

-11^{2} = 121

A 1 km long train travelling at a speed of 60km/h enter a tunnel 1km long. What time will the train take to come out of the tunn
zysi [14]

Answer:

2 minutes

Step-by-step explanation:

The front of the train enters the tunnel and travels 1 km before the rear of the train enters the tunnel.  Thus, the total distance traveled by the front of the train is 2 km, and this is covered in a certain number of hours:

Since distance = rate times time, time = distance / rate.  In this particular case we have:

                                              2 km

time = distance / rate = ------------------- = (1/30) hr

                                           60 km/hr

(1/30) hr converts to 2 minutes, since 1 hr = 60 minutes

Sue graphed the formula for converting temperatures from Fahrenheit to Celsius.If the temperature is 50 degrees Fahrenheit, what
kherson [118]

Answer:

10°C

Step-by-step explanation:

The temperature is 50°F

Let's assume that 50°F = x°C

The formula is;

(x°C × \frac{9}{5}) + 32 = 50°F

\frac{9}{5}x°C = 50 - 32 = 18

\frac{9}{5}x°C = 18

x°C = \frac{5}{9} × 18 = 10°C

So 50°F is equal to 10°C.

The line should equal 180 degrees, so we would subtract 122 from 180 to get 58 degrees. Since the triangle is equilateral, each angle is the same measure, so I believe m<1 should be 58 degrees.

elena55 [62]

Answer:

Each student club must contribute $ 33.33 in order to meet the fundraising goal.

Step-by-step explanation:

Given that a school fundraiser has a minimum target of $ 500. Faculty have donated $ 100 and there are 12 student clubs that are participating with different activities, to determine how much money should each club raise to meet the fundraising goal, the following calculation must be performed:

(500 - 100) / 12 = X

400/12 = X

33,333 = X

Thus, each student club must contribute $ 33.33 in order to meet the fundraising goal.
