Question 16
Given
Two golfers completed one round of golf.
The first golfer had a score of +6 and the second golfer had a score of -3.
To determine:
How many more shots did the first golfer take?
Explanation
Let 'n' be the number of shots taken by the first golfer
Since the first golfer had a score of +6 and the second golfer had a score of -3.
It means the 1st golfer must be 6 over par, and the 2nd golfer is still under 3.
Hence, we can map the situation using an equation
Adding -3 to both sides of the equation
Therefore, the 2nd golfer took 9 more shots.
Question 17
Answer:
The balance will be: 55
Step-by-step Explanation:
Credit means:
Debit means:
Hence, we can determine the balance using the equation.
Balance = 84 + (-29)
= 84 - 29
= 55
Therefore, the balance will be: 55
Answer:
I did this for points just saying:
I think the answer is 25.0?
Step-by-step explanation:
I'm not sure but I did this:
m∠TOU + m∠UOR + m∠ROS = m∠TOS We have:
m∠TOU = (3x - 14)°
m∠UOR = (3x - 14)°
m∠ROS = (2x + 8)°
m∠TOS = 180°
Substitute:
(3x - 14) + (3x - 14) + (2x + 8) = 180 combine like terms
(3x + 3x + 2x) + (-14 - 14 + 8) = 180
8x - 20 = 180 add 20 to both sides
8x - 20 + 20 = 180 + 20
8x = 200 divide both sides by 8
8x/8 = 200/8
x = 25
Identify your variables and then list what you know about them:
car's speed: 60 mph
time initially traveled by car: 2 hours
distance the car has traveled west after 2 hours: (60 mph)(2 hr) = 120 mi
truck's speed: 55 mph
distance traveled by truck in h hours: (55 mph)h
distance traveled by car = initial 120 miles plus (60 mph)h
total distance traveled by both vehicles:
(55 mph)h + 120 miles + (60 mph)h = 407.5 miles
Solve this equation for the time, h, and then add 2 hours to your result:
(55 mph + 60 mph)h + 120 mi = 407.5 mi
(115 mph)h = 287.5 mi. Solve this for h. Remember that when h was 0, the car had already been traveling 2 hours. Thus, add 2 hours to h to obtain your final answer: "how many hours does the car travel?"
Answer:
Total distance is 8 meters.
Step-by-step explanation:
First, let's take the equation and analyse it:
v(t) = 6 + t²
The delta t = 2
To find the acceleration, we need to differentiate v with respect to t like this:
dv/dt = d/dt (6 + t²)
= 2t
At t = 2, the change in velocity (dv/dt) = 2×2 = 4 m/s². This is the acceleration,a
The final velocity is given by v = 6 + (2)²
= 10 m/s
The distance is given by the formula:
s = ut + 1/2at²
initial velocity, u = 0
Therefore, the equation becomes s = 1/2at²
= 1/2× 4×4
=<u> 8 m Ans</u>
