Answer:
Participant A
Step-by-step explanation:
Rate: jumping jacks per minute
Rate of A: 120jjs / 10mins = 12 jumping jacks per minute
Rate of B: 140jjs / 14mins = 10 jumping jacks per minute
Answer:
x = 19.
Step-by-step explanation:
By the tangent - secant theorem:
BD^2 = AB * EB
so:
8^2 = (x - 7 + 4) * 4
4(x - 3) = 64
4x - 12 = 64
4x = 64 + 12 = 76
x = 76/4
= 19.
Answer:
<em>Question 3. Option B,</em>
<em>Question 4. Option D,</em>
<em>Question 5. Option B</em>
Step-by-step explanation:
Question 3.
If we have a table, we can note that each juice has a proportionality among one another - comparative to the number of servings. If we can figure out this proportionality, we can apply it to the servings of grapefruit juice;
As we can tell, this " proportion " is 1 to 2. Thus, the amount of grapefruit for 16 servings is 2 * 3 = 6c -<em> Option B</em>
Question 4.
The distance Carlos biked is 24 miles, the total distance he covered is 30 miles;
Question 5.
If 1 / 6 of the fruits are oranges, there must be 6 times of the other fruit. Thus, the solution is <em>Option B</em>
<u>Part 1</u>
The gradient of the line is , so the equation is .
This means the system is
<u>Part 2</u>
Substituting in the coordinates (-3,11) and (2,1) into the equation of the parabola,
Subtracting the equations, we get 10=5a, and thus a = 2
Substituting a = 2 back into the system, we get b = -7
<u>Part 3</u>
The equation of the parabola is , and the turning point is at . Therefore, the value of y is -7
One. This is because there is only one hundred.
