Brandon currently runs the mile in 6.8 minutes.

1 answer:

7 0

6 mins 38 seconds

.8 of 60 secs is 48 seconds so his time is 6 mins and 48 seconds, cutting off 10 seconds gives a new time of 6 mins 38 seconds

If Joe's heart beats 1,200,703 times

professor190 [17]

11 days, 21 hours, and 52 minutes have elapsed

(this answer is assuming he would have a normal heart rate of 70 bpm)

First, you would divide 1,200,703 by 70:

1,200,703/70=17,152.9

This is the amount of minutes that have elapsed.

Then, you convert the minutes to hours by dividing by 60:

17,152.9/60=285.8816667 (285 hours and 52 minutes)

This gives you how many hours and minutes have elapsed.

Finally, you calculate the number of days that have elapsed by dividing 285 by 24 (there are 24 hours in a day):

285/24=11.875 (11 days and 21 hours).

Put all of the amounts together to get the final answer:

11 days, 21 hours, and 52 minutes have elapsed

Observe the figure drawn, in which a square of side 15cm is removed from one corner of the given rectangle. Find the perimeter o

maxonik [38]

Step-by-step explanation:

Let's start by finding the area of figure 1

The square:

15cm×15cm=225cm²

Then we're going to find the area of figure 2

it's a rectangle (A=L×W)

L=60cm-15cm(because those cm have been cut off)=45cm

W=40cm

Area=45cm×40cm

=1800cm²

Then we add up the sum

Area of 1+Area of 2

=225cm²+1800cm²

=2025cm²

What is the minimum value for z = -x + 3y over the feasibility region defined by the constraints shown above?

natima [27]

Answer:

The minimum value for $z=-x+3y$ over the feasibility region is -1.

Step-by-step explanation:

Given conditions:

The function $z=-x+3y$

Subject to the following constraint

$x\geq 1$

$x\leq 7$

$y\geq 2$

$y\leq \frac{-1}{3}x+6$

Graph the region correspond to the solution of the system of constraints as given below.

Now, from the graph we have the coordinates of the vertices of the region formed.

The vertices are $(1,2)$ , $(7,2)$ , $(1,5.667)$ and $(7,3.667)$ .

now, evaluate the function $z=-x+3y$ at each vertex.

At $(1,2)$ ,

$z=-1+3\cdot 2=-1+6=5$

At $(7,2)$ ,

$z=-7+3\cdot 2=-7+6=-1$

At $(1,5.667)$

$z=-1+3\cdot 5.667=-1+17.001=16.001$

At $(7,3.667)$

$z=-7+3\cdot 3.667=-7+11.001=4.001$

So. the minimum value of function $z=-x+3y$ over the feasible region is -1.

The meal costs $52.95 for 5 people. Jenna ordered a dessert for $2.50. If Jenna deducts this amount from the total, how much wil

lubasha [3.4K]

Answer: $12.61

Step-by-step explanation:

Given : Total cost of meal for 5 people = $52.95

Jenna ordered a dessert for $2.50.

Total cost other 4 need to pay = $ (52.95- 2.50) = $ 50.45

Now , each person will pay $=\$\dfrac{50.45}{4}\approx \$12.61$

Hence, each of the other person need to pay $12.61 .
