Answer:

75

Step-by-step explanation:

<u>1. Set up a ratio proportion</u>

<u />\frac{30}{40} =\frac{x}{100}

<u>2. Cross Multiply</u>

3000=40x

<u>3. Divide both sides by 40 to isolate x</u>

<u />\frac{3000}{40} =\frac{40x}{40}

<u>4. Solve</u>

75=x

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

What is the answer to this question?
levacccp [35]
Angle A of triangle ABC will be ...
  ∠A = θ₂ -θ₃ = 77° -26° = 51°
Angle B of triangle ABC will be ...
  ∠B = 180° -θ₂ -θ₁ = 180° -77° -44° = 59°
Then angle C will be ...
  ∠C = 180° -∠A -∠B = 180° -51° -59° = 70°

By the Law of Sines,
  a/sin(∠A) = c/sin(∠C)
  a = c×sin(∠A)/sin(∠C)
  a = (57 yd)×sin(51°)/sin(70°) ≈ 47.14 yd

The distance from B to C is 47.14 yd.
