Mark cycled 25 miles at a rate of 10 minutes per hour. How long dis it take Mark to cycle 25 miles

Answers

Answer:

2.5 hours.

Step-by-step explanation:

We have been given that Mark cycled 25 miles at a rate of 10 miles per hour.

To find how many hours Mark took to cycle 25 miles we will divide 25 by 10.

\text{Time taken by Mark to cycle 25 miles}= \frac{25\text{ miles}}{10(miles)/(hour)}

\text{Time taken by Mark to cycle 25 miles}=\frac{25\text{ miles}}{10}* \frac{\text{hour}}{\text{miles}}

Upon cancelling out miles from numerator and denominator we will get,

\text{Time taken by Mark to cycle 25 miles}=(25)/(10) \text{ hour}

\text{Time taken by Mark to cycle 25 miles}=2.5\text{ hour}

Therefore, Mike will take 2.5 hours to cycle 25 miles.

Sue bought ten items at an average price of $3.60. The cost of eight of the items totaled $30. If the other two items were the same price, what was the price she paid for each ?1) $15, 2) $7.50, 3) $6, 4) $3, 5) $1.50I guess the answer is $7.50.What is yr answer ???

Answers

4) $3
Total price of the 10 items= $3.6x10=$36
The cost of the other two items=$36-$30=$6
The cost of each of the two= $6/2(because they are the same price)
                                       =$3


The answer is 4.) $3 each

She bought 8 items at $30 so those cost $3.75 each

8*$3.75=$30 

then add $6 +30= $36

$36/10 = $3.60 for average cost of each item

so the other 2 items cost $3 each 

Delilah received a stipend of $1,000 for the extra work she does on the job. She is going to deposit the money into her bank account that receives 4% simple interest.The account balance after year 3 is what

Answers

Answer:

$1,120

Step-by-step explanation:

Interest I = PRT/100 where P = amount deposited, R = rate percent and T = time.

So I =  (1000 * 4 * 3) / 100

= $120.

So the account balance is 1,120 dollars.

Determine the number of solutions to a system of equations.y = -6x-2, y = -6x-2
One Solution
No Solution
Infinitely Many Solutions
y = 0.5x + 5, y = 0.5x + 1
y = 0.25x - 2. y = 5x - 4
y = 2x + 3. y = 4x -1
y = 2x + 1.5, y = 2x + 1.5
y = -x - 3y = -x + 3

Answers

y = - 6x - 2 and y = - 6x - 2 has infinitely many solutions.

y = 0.5x + 5 and y = 0.5x + 1 has no solution.

y = 0.25x - 2 and y = 5x - 4 has one solution.

y = 2x + 3 and y = 4x -1 has one solution.

y = 2x + 1.5 and y = 2x + 1.5 has infinitely many solutions.

y = -x - 3 and y = -x + 3 has has no solution.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

  • If the slopes are different then one solution.
  • If the slopes are the same but intercepts are different then no solution.
  • If the slopes and intercepts are the same then infinitelymany solutions.

y = - 6x - 2 and y = - 6x - 2 has infinitely many solutions.

y = 0.5x + 5 and y = 0.5x + 1 has no solution.

y = 0.25x - 2 and y = 5x - 4 has one solution.

y = 2x + 3 and y = 4x -1 has one solution.

y = 2x + 1.5 and y = 2x + 1.5 has infinitely many solutions.

y = -x - 3 and y = -x + 3 has has no solution.

#SPJ2

Step-by-step explanation:

When we compare 2 system of equations (of the form y = mx + c), we take note of the following things:

  • If the values of m and c in both equations are the same, they have infinitely many solutions
  • If only the value of m is the same, they have no solutions
  • If neither is the same, they have 1 solution

Bearing this in mind, we have the following answers:

y = -6x - 2 and y = -6x - 2

=> Infinitely many solutions

y = 0.5x + 5 and y = 0.5x + 1

=> No solutions

y = 0.25x + 2 and y = 5x - 4

=> 1 solution

y = 2x + 3 and y = 4x - 1

=> 1 solution

y = 2x + 5 and y = 2x + 5

=> Infinitely many solutions

y = -x - 3 and y = -x + 3

=> No solutions
