Answer:

105,660 times

Step-by-step explanation:

7 times 65=445 times 60=26 700

2 times 118=236 times60=14 160

15 times 72=1080 times 60=64 800

26700 plus 14 160 plus 64 800=105,660

Answer:

105,540 beats

Step-by-step explanation:

10:00-5:00 is 7 hours long so

60(minutes)×7=420 minutes

since his heart beats 65 times/min.

420×65=27,300 beats

5:30-7:30 is 2 hours long so

60(minutes)×2=120 minutes

120×118=14,160 beats

7 hours+2 hours=9 hours

24-9=15 hours

60×15=900 minutes

900×72 beats=64,800 beats

Add all heart beats together

27,300+14,160+64,080=105,540

Answer: when x = 7, y = 16

Step-by-step explanation: Here, we know that y varies inversely as x.

When we have two sets of inversely related coordinates, x₁ and y₁,

and x₂ and y₂, we can use the product rule, shown below,

to find the missing value.

<h2>x₁ y₁ = x₂ y₂</h2><h2 />

Here, we know that y = 14 when x = 8 so

one set of coordinates will be 8 and 14.

We want to know the value of y when x = 7.

So our other coordinates will be 7 and y.

So we have (8)(14) = (7)(y).

Simplifying, (8)(14) is equal to 112 and (7)(y) is equal to 7y.

So we have 112 = 7y.

Now we simply solve for y by dividing both sides of the equation by 7.

The 7's on the right side cancel out and

on the left, 112 divided by 7 is equal to 16.

So we have 16 = y.

So when x is equal to 7, y is equal to 16.

Sarah has a wall hanging in the shape of a parallelogram. What is the height of the wall hanging if its area and base are 300 sq
Anastasy [175]
Use the formula
Area= base times height.
You're given that area =300cm^2 and base=20 cm.
Plug these into the equation to get 300=20 x height. Now, you just need to solve for height. To do this, you need to undo the multiplication of b x h by dividing the area by the base.
So, h = 300/20

What is the vertex of the quadratic function f(x) = (x – 8)(x – 2)?
LekaFEV [45]
Something funny is that the x value of the vertex lies directl in the middle of the x intercepts
so
we see the x intercepts or 0's at x=8 and 2
the average is x=5
so find f(5) to find the y value of the vertex
f(5)=(5-8)(5-2)
f(5)=(-3)(3)
f(5)=-9

vertex is at (5,-9)

the actual way the teacher wants is to expand then compltete the square to get into the form f(x)=a(x-h)^2+k where the vertex is (h,k)
but whatever


verrtex is at (5,-9)
