Answer:

To find ratio mph (miles PER hour), we can write the information given as a fraction. (The miles will go on top and the number of hours will go on the bottom).

1/2=.5 miles

1/4-.25 miles

So we have .5miles/.25 hours

From here, we can do 2 things: divide to get 2miles/hour or you can see that you can reduce the fraction (.5/2=.25 and .25/.25=1). So again we get 2/1 miles per hour OR 2 mph

Hope that helps,

This is an Isoceles triangle. That means 180˚-50˚=130˚

130˚/2=65˚

Answer:

D) 65

Step-by-step explanation:

x + x + 50 = 180

2x + 50 = 180

2x = 130

x = 65

Answer:

  3.67 years

Step-by-step explanation:

The amount is found using the compound interest formula.

  A = P(1 +r/n)^(nt)

for principal P invested at annual rate r compounded n times per year for t years.

We can solve this for t:

  A/P = (1 +r/n)^(nt) . . . . divide by P

  log(A/P) = (nt)log(1 +r/n) . . . . take the logarithm

  t = log(A/P)/(n·log(1 +r/n)) . . . . divide by the coefficient of t

Filling in the given values, we find ...

  t = log(12000/10000)/(4·log(1 +0.05/4)) ≈ 3.6692

It will take about 3.67 years for the balance to reach $12,000.

Answer:

the answer is 3.67 years

Answer:

  76.5 units

Step-by-step explanation:

This is an interesting question. The side lengths are proportional to the sine of the opposite angle. So, we can find a scale factor for the given length by adding the sines of the angles and dividing by the sine of the angle opposite the given side.

The three angles are ...

  43°, 63° and 74° (the supplement of the sum of the other two)

So, the scale factor mentioned above is ...

  (sin(43°) +sin(63°) +sin(74°))/sin(74°) ≈ 2.636396

Then the perimeter of the triangle is ...

  (2.636396)(29) ≈ 76.5 . . . units

The function representing the mass of Element X after t days is [tex]{\text} M(t) = 390 * (0.41)^t[/tex], and the percentage rate of change per hour is 2.46%.

Given:

Initial mass = 390 grams

Rate of decay = 59% = 0.59

The general form of an exponential decay function is:

[tex]{\text}y = a (1 - r)^t[/tex]

So, the function to represent the mass of the sample after t days would be:

[tex]{\text} (t) = 390 * (1 - 0.59)^t[/tex]

Simplifying this equation gives

[tex]M(t) = 390 * (0.41)^t[/tex]

Now, the hourly rate of change is

Hourly rate of change = 0.59 / 24  

                                     = 0.024583

                                     = 2.46% per hour.

Therefore, the function is [tex]{\text} M(t) = 390 * (0.41)^t[/tex]and the rate of change is 2.46%.

Answer: 27.1 cubic meters

Step-by-step explanation: The area for finding the volume of a pyramid is V=1/3 Bh, where B= base, and h=height. To substitute in the numbers from the problem, you get V=1/3 times 8.3 times 9.8. 9.8 times 8.3 is 81.34. 81.34 times 1/3 rounds to 27.1.

Not to conclude that the drug is safe, when, in fact, it is safe.

Step-by-step explanation:

A type ii error is an error that occurs in a hypothesis testing when a person goes ahead to accept a null hypothesis when it is actually false and should be rejected.

To continue, here are the hypothesis:

H0: the drug is unsafe

H1: drug is safe.

A type ii error was committed here because H0, which is the null was accepted and it was concluded that the drug was unsafe, When in fact it should have been rejected. The conclusion should have been that the drug was safe.

Step-by-step explanation:

The Volume of rectangular Pyramid whose height inches is 40 cubic inches.

The volume of the rectangular pyramid is defined as the capacity of the rectangular pyramid. In geometry, a rectangular pyramid is a three-dimensional geometric shape that has a rectangular base and four triangular faces that are joined at a vertex.

Here, height of pyramid = 6 inches

base area = 4 X 5 = 20 sq. inches

Volume of rectangular pyramid = 1/3 × Base Area × height

                                                       = 1/3 X 20 X 6

                                                      = 120 / 3

                                                      = 40 cu. inches

Thus, the Volume of rectangular Pyramid whose height inches is 40 cubic inches.
