Question

What are the angles that are coterminal with an angle of rotation of 300 degrees?

Solution 1

**Answer:**

-60Â° and 660Â°

**Step-by-step explanation:**

Coterminal are angles that have the same terminal side when in standard position.

To obtain an angle coterminal with an angle of rotation of 300 degrees, we add 360Â° to obtain:

300Â°+360Â°=660Â°

We also subtract 360Â° to obtain:

300Â°-360Â°=-60Â°

This is because an angle of rotation could be in the clockwise or counterclockwise direction.

Question

Solve by factorisation 2x^2+3x-20=0

Solution 1

After factorizing the equation, we get "**x = 4** and** x = -5**".

Given:

By applying the **factorization**, we get

Solution 2

x = -4 or x = 2.5

**Step-by-step explanation:**

2x^2 + 3x - 20 = 0

(x + 4) (2x - 5) = 0

either x + 4 = 0 or 2x - 5 = 0

x = -4 or x = 2.5

Question

Which expression shows the increase in average temperature, t, from February to March? A 27 â€“ t = 37
B 27 + t = 37
C 27t = 37
D 37 Ã· t = 27

Solution 1

I think the answer is c

Solution 2

The answer will be B. 27+t=37 because the temperature is increasing in other words adding.

One-sixth
One-fourth
Five-twelfths

Solution 1

**Answer:**

Five-twelfths - 5/12

**Step-by-step explanation:**

There are twelve months in a year

Five of these months starts with either letter J or M (January, March, May, June and July)

Question

How many two and a half pound chunks of cheese can be cut from a single 20-pound piece of cheese?â€‹

Solution 1

**Answer:**

8

**Step-by-step explanation:**

Solution 2

**Answer:**

8

**Step-by-step explanation:**

divide 20 by 2.5

25 can go into 200 eight times

eight times 25 equals 200 so 8 is your answer.
