A marathon runner completes a 42km course at an average speed of 7km/h. Calculate the time taken to complete the course.

Answers

Answer 1

Answer:

t = 6 hours

Step-by-step explanation:

Given that,

Average speed, v = 7 km/h

Distance, d = 42 km

We need to find the time taken to complete the course. The average speed is given by :

[tex]v=\dfrac{d}{t}\\\\or\\\\t=\dfrac{d}{v}\\\\t=\dfrac{42\ km}{7\ km/h}\\\\t=6\ h[/tex]

So, the time taken to complete the course is 6 hours.

Or... Are there no solutions or infinite solutions

Answers

Answer:

there are no solutions

Step-by-step explanation:

5x−7x+6=−2(x−3)

Step 1: Simplify both sides of the equation.

5x−7x+6=−2(x−3)

5x+−7x+6=(−2)(x)+(−2)(−3)(Distribute)

5x+−7x+6=−2x+6

(5x+−7x)+(6)=−2x+6(Combine Like Terms)

−2x+6=−2x+6

−2x+6=−2x+6

Step 2: Add 2x to both sides.

−2x+6+2x=−2x+6+2x

6=6.

Step 3: Subtract 6 from both sides.

6−6=6−6

0=0

there for there are no solutions

A local boys club sold 156 bags of mulch and made a total of $288 it's so two types of mulch hardwood for two dollars a bag and pine board for $1.75 a bag how many bags of each kind of mulch didThe boys club sold ____ bags of hardwood mulch and _____ bags of pine bark mulch.

Answers

I wish I saved my answer from the other day, LOL...

we’ll use h for # of bags of hardwood mulch, and p for # of bags of pine bark mulch

h + p = 156

2h + 1.75p = 288

First we’ll solve for h in terms of p

h = 156 - p
Then substitute that into the equation with the money

2(156 - p) + 1.75p = 288
312 -2p + 1.75p = 288
-0.25p = -24
0.25p = 24
p = 96

Drop that into the equation for numbers of bags
h = 156 - p
h = 156 - 96
h = 60

Check the math:
2h + 1.75p = 288
2(60) + 1.75(96) = 120 + 168 =288

The rate of change is
.

Answers

Rate of change of function  on the interval  is; 6.

Step-by-step explanation:

Given the function:  on the interval

Rate of change of function: Let f be the function defined on the interval , then the rate of change of function A(x) is given by:

A(x) =

at x = 2;

h(2) =

and at x = 4

h(4) =

then, by the definition of rate of change of function:

A(x) =

Substitute the value of h(2) = 4 and h(4) = 16 we have;

Therefore, the rate of change of function is 6.

Jenny has 68 1/2 pages of her book left to read. How many pages will she have left after she reads 26 1/6 pages?​

Answers

Answer: 42 1/2

Step-by-step explanation:

We subtract 26 1/6 from 68 1/2. We do this by finding the LCM of 6 and 2. That is 6. We multiply 1/2 by 3/3 to get 3/6. Now, we subtract. 68 - 26 is 42, and 3/6 - 1/6 is 2/6. Our answer is 42 2/6. That can be simplified to 42 1/3.

Answer:

42 1/3

Step-by-step explanation:

Subtract 26 1/6 from 68 1/2 by finding the lowest common denominator (6).
