Mary borrowed $840 from her friend to help pay for a trip. She paid him $40 every
week until the debt was paid.
How many weeks did it take Mary to pay her debt?
A. 40
B. 35
C. 32
D. 21

Answers

Answer 1

Answer:

d.21

Step-by-step explanation:

840/40=21

Answer 2

Answer:

21 Weeks

Step-by-step explanation:

$840 ÷ 4 weeks = 21

You can also reverse work this by multiplying $40 by the other choices!

$40 x 40 = $1600

$40 x 35 = $1400

$40 x 32 = $1280

$40 x 21 = $840

As we can see, D is the only answer that makes sense, therefore 21 weeks is the answer.

A train is traveling at a constant speed and goes a distance of 7 1/2 kilometers in 6 minutes the train will continue at this speed the train will travel a distance of d kilometers in m minutes write an equation that represents the relationship between d and m

Answers

Answer:

392939939393939399393939393

Step-by-step explanation:

An equation that represents the relationship between d and m can be written as d = 1.25 m.

What is Speed?

Speed of an object is the rate of change of position of an object in any direction.

Speed is a scalar quantity because it does not have any direction, it only has magnitude. Speed with direction is called velocity.

The formula for calculating speed is,

Speed = Distance / Time

Given distance the train travelled = 7 [tex]\frac{1}{2}[/tex] kilometers

                                                        = 15/2 kilometers

                                                        = 7.5 kilometers

Time taken to travel the distance = 6 minutes

Speed = 7.5 / 6

           = 1.25 kilometers / minute

Given that speed of the train is constant.

Hence for any distance 'd' kilometers in 'm' minutes,

d / m = 1.25

d = 1.25m

Hence d and m can be related by the equation d = 1.25m.

III. 15,560 yards

Which run(s) are at least 15 kilometers?

Option A: I, only
Option B: II, only
Option C: I and III
Option D: II and III

Answers

the answer to this problem is B, I just converted the value to km

The values of following are 10 yards = 0.009144 km, 44,880 feet = 13.678, 15,560 yards = 14.228

What is kilometer ?

"The kilometer spelt kilometer in American English, is a unit of length in the metric system, equal to one thousand meters (kilo- being the SI prefix for 1000). It is now the measurement unit used for expressing distances between geographical places on land in most of the world; notable exceptions are the United States and the United Kingdom where the statute mile is the unit used."

Given,

(i) 10 yards

1 yard = 0.0009144

then 10 yard = 10*0.0009144 = 0.009144 km

(ii) 44,880 feet

1 feet  = 0.00030478

then 44,880 feet = 44,880*0.00030478 = 13.678 km

(iii) 15,560 yards

15,560 yards =  15,560 *0.0009144 = 14.228 km  

Hence, D is the correct option.
