Answer 1

Answer:

9 AM

Step-by-step explanation:

Let t = traveling time of the 1st train, when the 2nd train catches up

Then

(t-3) = traveling time of the the 2nd train.

When this occurs, both trains will have traveled the same distance;

Write a distance equation: Dist. = speed * time

100(t-3) = 80t

100t - 300 = 8t

100t- 80t = +300

20t = 300

t = 300/20

t = 15 hrs.

Time = 6 PM + 15 hrs. = 9 AM the next day

Answers

Answer:

(43 - 56) + 13 = 0 points

Step-by-step explanation:

We start with 43 points and loose 56 -- 43-56

then, 13 points are gained = (43 - 56) + 13

simplify and solve:

-13 + 13 = 0

12. The perimeter of a rectangle is 50 feet. The width is 5 less than the
length. What are the dimensions of the rectangle? (Write your answer as
Length, Width)

Answers

Step-by-step explanation:

Length = x

Width = (x-5)

Perimeter = 2 lengths + 2 widths

50 ft = x + x + (x-5) + (x-5)

50 ft = 4x - 10

60 ft = 4x

15 ft = x

length = x = 15 ft

width = (x-5) = (15 -5) = 10 ft

dimensions = length × width

= 15 ft × 10 ft

if you wanna check,

50 ft = x + x + (x-5) + (x-5)

50 ft = 15 + 15 + (15-5) + (15-5)

50 ft = 30 +(10+10)

50 ft = 30 + 20

50 ft = 50

1. Point M is on PQ, PM has a length of 7 units, and point N is the midpoint of MQ. If the length of NQ
is 4 units, how long is PQ?
PA
A 3 units
B. 11 units
C. 15 units
D. 18 units

Answers

Answer:

C. 15 units

Step-by-step explanation:

PM = 7 units

p..............M..........N............Q

   7 unit                     4 unit

NQ = 4 units

Given that

N is midpoint of MQ

it means N divides MQ into two equal parts

thus

MN = NQ = 4 units

now

we have to find length of PQ

p..............M..........N............Q

   7 unit     4 units     4 unit

PQ = PM + MN + NQ

PQ = 7 units + 4 units + 4 units = 15 units

thus, correct answer is option c 15 units

Answer:

15 units
