Answer: B
Reason:
44 + x
66
x
22
Also when we have a greater and equal to sign (
), it will be a filled in circle.
Thats why its by.
Answer:
r = 12
Step-by-step explanation:
From the figure attached,
QP is a tangent to the circle O at the point P.
Therefore, by the property of tangency,
OP ⊥ QP
By applying Pythagoras theorem In right triangle QPO,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
(OQ)² = (OP)² + (PQ)²
(25 + r)² = (35)² + r²
625 + r² + 50r = 1225 + r²
50r = 1225 - 625
50r = 600
r = 12
Therefore, r = 12 units is the answer.
<span>If x = Jamal's age , 2x = Wilma's age , x - 3 = Tim's age.
The sum of the ages is 17.
Jamal's age is 5
Wilma's age is 10
Tim's age is 2
Hope this helps!</span>
Remark
You have given the second best answer. Your answer is |x|<1. You should have open circles at 1 and - 1.
Solution
I have enclosed a graph that is not a number line. You could confine yourself to a number line just by tracing out the blue solution (which is the answer you want)
The red solution is what you did.
The blue solution does not include x = 1 nor does it include x = - 1. The number line would show 1 < x < ∞ and -∞ < x < -1
You can do 280/40 would give you the answer for one minute, then whatever you get, multiply be 280, that is your answer for number 14.so it would be for every one minute you ride 7 miles. so it would be 7 miles times 20 minutes because you are calculating for an hour and we already have 40 minutes, it would give you 140 miles for 20 minutes, then you add 140 +280 which would give you your answer which is 420m/hr. if you read it step by step you would be able to understand.<span />
