Two cars travel at the same distance. The first car travel at 50 miles per hour and reaches its destination at t hours. The second car travels at a rate of 60 miles per hour and reaches its destination 1 hour earlier than the first car how long does it take for the first car to reach its destination
Answers
Answer:
The first car reaches its destination in 6 hours.
Step-by-step explanation:
Speed of the first car = 50 miles per hour
Time taken = t hours
Distance travelled = Speed × Time = 50 t
Speed of the second car = 60 miles per hour
Time taken = [tex](t-1)[/tex] hours
Distance travelled = Speed × Time = [tex]60(t-1)[/tex]
As two cars travel the same distance,
[tex]50t=60(t-1)\\50t=60t-60\\60=60t-50t\\60=10t\\t=\frac{60}{10}\\t=6[/tex]
So, the first car reaches its destination in 6 hours.
It would take the first car 6 hours to reach its destination.
Speed is the ratio of distance to time. It is given by:
Speed = distance /time
Since the two cars travel at the same distance, let d represent this distance.
The first car travel at 50 miles per hour and reaches its destination at t hours. Hence:
50 = d / t
d = 50t (1)
The second car travels at a rate of 60 miles per hour and reaches its destination 1 hour earlier than the first car. Hence the time = t - 1. Hence:
60 = d / (t - 1)
d = 60(t - 1)
d = 60t - 60 (2)
Equating both equations gives:
50t = 60t - 60
10t = 60
t = 6 hours
Hence it would take the first car 6 hours to reach its destination

8. The total weight of a vase and its packaging is: 4 lb. 7 oz. The vase by itself
weighs 3 lb. 11 oz. What is the weight of the packaging materials?
(a) 8 lb. 2 oz.
(d). 6 oz.
(b) 12 oz.
(e) none of these
(c) 1 lb. 4 oz.
Please show the work
Answers
Answer:
E
Step-by-step explanation:
the weight of the packaging materials is 12 oz. There are 16 oz in a pound. If the vase weighs 3 lb 11 oz, it would take 5 more oz to reach the next pound, and there was another 7 oz after that. You would then do 5 + 7, which is 12, so the packaging materials weigh 12 oz.

What compound inequality describes this graph
Answers
Answer:
0≥x<4
Step-by-step explanation:
first, let's look at this number line.
there is a closed circle at 0 and an open circle at 4. this means that 0 is included (≤ or ≥) and that 4 is not included (< or >).
these are the endpoints, meaning that in this compound inequality, the numbers next to the symbols are 0 and 4.
x is in the middle of this compound inequality.
0 x 4
now, we have to figure out the symbols in between. i wrote out our choices above for each number. the highlighted portion is greater than or equal to 0 and less than 4, so we can write this compound inequality as the following:
0≥x<4
x is greater than or equal to 0, but less than 4

Answers
Answer:
Shirts : $24
Pants : $23.80
Shoes : $21
Ties : $30.60
Step-by-step explanation:
For the shirt : Price = $15 Discount = 20% 2 shirts are bought
Price after the discount = (100% - 20%) x (2 x $15) = $24
For the pair of pants : Price = $28 ; Discount = 15% ; 1 pair of pants is bought
Price after the discount = (100% - 15%) x $28 = $23.80
For the shoes : Price = $35 Discount = 40% 1 pair of shoes are bought
Price after the discount = (100% - 40%) x $35 = $21
For the tie: Price = $12 Discount = 15% 3 ties are bought
Price after the discount = (100% - 15%) x ( 3 x $12) = $30.60
Answer:
Shirts : $24
Pants : $23.80
Shoes : $21
Ties : $30.60
Step-by-step explanation:
For the shirt : Price = $15 Discount = 20% 2 shirts are bought
Price after the discount = (100% - 20%) x (2 x $15) = $24
For the pair of pants : Price = $28 ; Discount = 15% ; 1 pair of pants is bought
Price after the discount = (100% - 15%) x $28 = $23.80
For the shoes : Price = $35 Discount = 40% 1 pair of shoes are bought
Price after the discount = (100% - 40%) x $35 = $21
For the tie: Price = $12 Discount = 15% 3 ties are bought
Price after the discount = (100% - 15%) x ( 3 x $12) = $30.60

Work Shown:
(angle HID) + (angle DIJ) = angle HIJ
(100) + (8x+11) = 21x+7
100+8x+11 = 21x+7
8x+111 = 21x+7
111-7 = 21x-8x
104 = 13x
13x = 104
x = 104/13
x = 8
Use this x value to find angle HIJ
angle HIJ = 21x+7
angle HIJ = 21*8+7
angle HIJ = 175 degrees
---------------------------
Extra info:
You can also use that x value to find angle DIJ
angle DIJ = 8x+11
angle DIJ = 8*8+11
angle DIJ = 75
Then add this to angle HID to get
angle HID + angle DIJ = 100+75 = 175
This matches with angle HIJ = 175
So this confirms angle HID + angle DIJ = angle HIJ which helps confirm our answers.

Solve the inequality: -6n - 12 >= 3(-n + 12)
Answers
Answer:
-16 > n or n < -16
Step-by-step explanation:
First, we can write the inequality and distribute.
-6n-12 > 3(-n+12)
-6n-12 > -3n+36
Get rid of a variable first (it makes solving a lot easier). We can add 6n to both sides.
-6n-12 > -3n+36
+6n +6n
-12 > 3n+36
Now, we can subtract 36 on both sides.
-12 > 3n+36
-36 -36
-48 > 3n
Divide by 3 on both sides.
-48 > 3n
/3 /3
-16 > n or (if it's easier) n < -16
