C is equal to 32 radians (the square root thing with 32 in it)
Answer:
B and C
Step-by-step explanation:
To determine which ordered pairs are a solution, substitute the coordinate points into the left side of the inequality and check against right side for validity.
A (3, 5)
25 - 9 = 16 ≥ 7 ⇒ (3, 5) is not a solution
B (- 2, - 5)
- 25 + 6 = - 19 ≤ 7 ⇒ (- 2, - 5) is a solution
C (5, - 3)
- 15 - 15 = 0 ≤ 7 ⇒ (5, - 3) is a solution
Answer:
8:30

Because 6 ÷ 4 is 1.5. also know as 1.5hrs before bedtime.
Answer:
Step-by-step explanation:
The given expression is
We want to find the value of h(-9).
We substitute r=-9 to obtain:
We multiply out to obtain:
We simplify the denominator to obtain:
This is the same as:
Answer:
2:5
Step-by-step explanation:
The ratio can be found by turning both values into either grams or kilograms. For this, I will make them both into grams.
1. 800g is already in grams, so leave it.
2. 2kg is in kilograms, and 1 kilogram = 1000 grams.
3. 2 kilograms is equal to 2000 grams.
4. For this reason, 800g: 2000g can be simplified by making 800g into 2, and 200g into 5.
<u>That is the ratio, 2:5</u>
