travis heart beats 17 times in 15 seconds. If he maintains this rate. how many times will it beat in 1min​

Answer:

The cargo plane flew 1208 miles, and it took 4 hours.

Step-by-step explanation:

4608 miles is the distance between the passenger plane and the cargo plane.

This distance can be expressed as the sum of the distance that the passenger plane had flown and the distance that the cargo plane had flown.

Distance Apart = Distance Flown (Passenger) + Distance Flown (Cargo)

So, to find the distance flown by the cargo plane, we need both the distance between the 2 planes and the distance flown by the passenger plane.

We know that the distance apart is 4608 mi.

We can find the distance flown by the passenger plane by multiplying its speed by the time it was flying.

[tex]distance = speed * time[/tex]

Speed = 425 mph

Time = 8 hours

[tex]distance\ (passenger) = 425 * 8\\distance\ (passenger) = 3400[/tex]

The passenger plane flew 3400 mi.

Now we can find the distance flown by the cargo plane:

Distance Apart = Distance Flown (Passenger) + Distance Flown (Cargo)

[tex]4608 = 3400 + distance[/tex]

Subtract 3400 from both sides:

[tex]1208 = distance[/tex]

The cargo plane flew 1208 miles.

If we want to find for how long it flew, we can divide the distance by its speed.

[tex]distance = speed * time[/tex]

[tex]time = \frac{distance}{speed}[/tex]

Distance = 1208 mi

Speed = 302 mph

[tex]time = \frac{1208}{302} = 4[/tex]

Answer: The cargo plane flew 1208 miles, and it took 4 hours.

Answer: No u didn't get it right

Step-by-step explanation:

Answer:

y = [tex]\frac{1}{9}[/tex] x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

y = - 9x + b ← is in slope- intercept form

with slope m = - 9

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-9}[/tex] = [tex]\frac{1}{9}[/tex] , thus

y = [tex]\frac{1}{9}[/tex] x + b ← is the partial equation

To find b substitute (- 18, 3) into the partial equation

3 = 2 + b ⇒ b = 3 - 2 = 1

y = [tex]\frac{1}{9}[/tex] x + 1 ← equation of perpendicular line

Answer:

-8

Step-by-step explanation:

Solve the equation:

-2m = 8 - m

-2m + m = 8

-m = 8

m = -8

If you would like to check the answer, plug the value of m back into the equation:

-2 (-8) = 8 - -8

16 = 16

Answer:

m = -8

Step-by-step explanation:

add m to both sides

-2m + m =8 - m + m

simplify

-m = 8

divide sides by -1

-m/-1 = 8/-1

simplify

m = -8

Answer:

Step-by-step explanation:

Let w represent the width of the playing field in yards. Then the length is 3w-3. The perimeter is given by ...

  P = 2(L+W)

  362 = 2((3w-3) +w)

  181 = 4w -3

  184 = 4w

  46 = w

  3(46)-3 = 135 . . . length

The playing field is 46 yards wide and 135 yards long.

Answer:

B is the correct answer for this question

Step-by-step explanation:

The number that could represent point Q is to be considered as the option c.  2 1/2.

Since

p = -4

q could be 6.5 units to the right or to the left of point p.

So, to the right it should be like

=p + q

= -4 +  6.5

= 2.5

Hence, The number that could represent point Q is to be considered as the option c.  2 1/2.

Answer:

b

Step-by-step explanation:

The decimal number 3.4 terminating decimal. So, it is rational number. Therefore, option B is the correct answer.

Rational numbers are in the form of p/q, where p and q can be any integer and q ≠ 0. This means that rational numbers include natural numbers, whole numbers, integers, fractions of integers, and decimals (terminating decimals and recurring decimals).

A) The decimal number 3.456733244… is not repeating and non recurring

So, it is irrational number

B) The decimal number 3.4 terminating decimal

So, it is rational number

C) Infinity is not a rational number because it is undefined as far as being an integer.

D) ∛4 =1.58740105197 is not repeating and non recurring

Hey there!

Your answer would be -32.5.

First, you would multiply both sides by 10, and simplify. That would bring you to 4x + 25 = 2x - 40. Now you can start isolating the varible. Subtract 25 from both sides, and simplify. That gives you 4x = 2x - 65. Next, subtract 2x from both sides, and simplify once again. That brings you to 2x = -65. Finally, divide both sides by 2 and once more, simplify. It gives you your answer x=-65/2 or -32.5

Answer:

BD and BC

Step-by-step explanation:

The angle is between this two lines

The rays BD and BC form the angle 65° in the figure.

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

When two lines or rays intersect at a single point, an angle is created.

Here, the angle measure is  65°.

An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

And it is created between two rays.

Answer:

The following properties hold for all events A, B.

• P(∅) = 0.

• 0 ≤ P(A) ≤ 1.

• Complement: P(A) = 1 − P(A).

• Probability of a union: P(A ∪ B) = P(A) + P(B) − P(A ∩ B).

For three events A, B, C:

P(A∪B∪C) = P(A)+P(B)+P(C)−P(A∩B)−P(A∩C)−P(B∩C)+P(A∩B∩C).

If A and B are mutually exclusive, then P(A ∪ B) = P(A) + P(B).

• Conditional probability: P(A | B) = P(A ∩ B)

P(B)

.

• Multiplication rule: P(A ∩ B) = P(A | B)P(B) = P(B | A)P(A).

• The Partition Theorem: if B1, B2, . . . , Bm form a partition of Ω, then

P(A) = X

m

i=1

P(A ∩ Bi) = X

m

i=1

P(A | Bi)P(Bi) for any event A.

As a special case, B and B partition Ω, so:

P(A) = P(A ∩ B) + P(A ∩ B)

= P(A | B)P(B) + P(A | B)P(B) for any A, B.

• Bayes’ Theorem: P(B | A) = P(A | B)P(B)

P(A)

.

More generally, if B1, B2, . . . , Bm form a partition of Ω, then

P(Bj | A) = P(A | Bj )P(Bj)

i=1 P(A | Bi)P(Bi)

for any j.

• Chains of events: for any events A1, A2, . . . , An,
