Answer is 360. Let me know if you need a. explanation. it's kind of weird. you have to sort of combine all the angles and see that they form a complete circle.
Beth travelled the remaining distance with an average speed of 52 mph
<u>Solution:</u>
Given, Beth drives 200 miles in 4 hours.
<em><u>The formula for distance speed is given as:</u></em>
--- eqn 1
<em><u>Calculating time taken for 18 miles:</u></em>
She drives the first 18 miles at an average speed of 36 mph.
Here distance = 18 miles
speed = 36 mph
Plugging in values in eqn 1 we get,
<em><u>Calculating average speed for the rest of the journey:</u></em>
Now, remaining distance = 200 miles – 18 miles = 182 miles
And time used for remaining journey = total time – time taken for first 18 miles
Plugging in values in eqn 1, we get
Thus the average speed for rest of journey is 52 mph
Answer:
Cameron found 23 quarters and 57 dimes.
Step-by-step explanation:
Let the number of quarters Cameron found = Q
And the number of dimes = D
Since, total number of coins were 80,
Q + D = 80 -----(1)
Total amount of the coins was $11.45,
0.1D + 0.25Q = 11.45
10D + 25Q = 1145
2D + 5Q = 229 -----(2)
Equation (1) multiplied by 2 then subtracted by equation (2),
(2D + 5Q) - 2(Q + D) = 229 - 2(80)
(2D - 2D) + (5Q - 2Q) = 229 - 160
3Q = 69
Q = 23
From equation (1),
23 + D = 80
D = 57
Cameron found 23 quarters and 57 dimes.
Answer:
(-20, 0)
Step-by-step explanation:
to find x intercept we have to substitute 0 into y and solve for x
0 = -x - 20
rewriting the equation
-x - 20= 0
-x = 20
