Answer:
1/1,000 chance of winning
Step-by-step explanation:
Answer:
Question 1: A
Question 2: C
Step-by-step explanation:
The answer to question 1 is A. I know this is correct because Max needs to earn 108 dollars for the headphones he wants so the amount of money he earns per hour which is 15, times the amount of hours he needs to work which is x has to be greater than 108. So, the inequality equation has to be 15x > 108 which is answer A.
The answer to question 2 is C. I know this is correct because Felicia has 2 sisters which make 3 sisters in total to pay for the gift. They all pay evenly, so the first part of the equation would be 3x. The cost for the gift is less than 80 dollars, so we write the inequality equation like 3x < 80 which is answer C.
x² + 7x - 4 = 0
a = 1, b = 7, c = -4
x = [-b +/- √(b² - 4ac)]/2a
= [-7 +/- √(49 + 4)]/2
= (-7 +/- √53)/2
The tip of the hand travels the circumference of a circle with radius (r) 9.5 cm every hour;
The formula for circumference of a circle (c) is:
c = πd = 2πr
So, for a circle with radius 9.5, the circumference is:
c = 2π(9.5)
= 19π cm
The tip travels 19π cm every hour, so in a day of 24 hours it will travel:
24 * 19π = 456π cm
(= 1432.566... ⇒ 1432.6 cm)
First, r<span>earrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : </span><span>3*(2*x-1)-(4*x+2)=0
= </span><span>3 * (2x - 1) - (4x + 2) = 0
= 2x - 5 = 0
= </span>2x-5 = 0<span> ---- </span><span>Add </span> 5 to both sides of the equation ---><span>
</span>= 2x = 5
Then you will divide both sides of the equation by 2 and get,
<span>= x = 5/2 OR 2.5
I hope this helps!</span>
