Answer:
Explanation:
Given that y varies inversely as x, we have:
SInce x = 7 whe y = 5, we can find k
k = 7*5 = 35
so
yx = 35
To find y
Answer: 75 students
Step-by-step explanation:
Skyler goes to a school that has 100 students in it. She asks 40 random students if they like the new 8.30 am start to the day and 30 of them say no they don't like it. This shows that: 30/40 = 3/4 of the students don't like it.
Since the school has 100 students, the number of students that doesn't like the 8.30 a.m start will be:
= 3/4 of 100
= 3/4 × 100
= 3 × 25
= 75
Answer: Choice B) Angle L = Angle O
---------------------------------------------------
---------------------------------------------------
If we know that Angle L is congruent to Angle O, then we can use the AAS (angle angle side) congruence property. We have one pair of angles marked by the square marker (angle J and angle M). So they are congruent angles. We have a pair of congruent sides JK = MN = 3. So we're just missing a pair of angles.
Note: The answer is NOT angle K = angle N because this would mean ASA would be used instead of AAS. The order of the letters is important as it establishes how the sides and angles relate. With ASA, the side is between the angles. With AAS, the side is not between the angles.
We can use quadratic formula to determine the roots of the given quadratic equation.
The quadratic formula is:
b = coefficient of x term = 5
a = coefficient of squared term = 1
c = constant term = 7
Using the values, we get:
So, the correct answer to this question are option E and F
