If the bus is 30km away, it has driven 270km. If it drives at 70km per hour, then your answer will be shown with 270/70, which is 3.85

Answer: 2.6 (rounded answer)

Step-by-step explanation: To solve for the side BC we can find the tangent (TAN) of 41 degrees. Since the tangent of an angle is equal to the opposite side over adjacent, we can set up an equation that looks like this, assigning side BC to be x:

tan(41)= x/16

0.1606567=x/16 <---- Use calculator to find tan(41)

0.1606567(16)=x/16(16) <---- Multiply each side by 16

2.5705071789=x

Answer:

The sorted inputs in order from least to greatest is:

3/21 < 3/15 < 3/11 < 3/8 < 3/7

Step-by-step explanation:

Using the given inputs:

3/15 3/7 3/21 3/8 3/11

As the least common denominator (LCD) is: 9240

Rewriting as equivalent fractions with the LCD:

3/15                  3/7                       3/21                 3/8                     3/11

1848/9240      3960/9240       1320/9240        3465/9240        2520/9240

Sorting this table by the numerators of the equivalent fractions in order from least to greatest:

    3/21                3/15                 3/11                     3/8                  3/7

1320/9240  < 1848/9240 < 2520/9240  < 3465/9240   <   3960/9240

Therefore, the sorted inputs in order from least to greatest is:

3/21 < 3/15 < 3/11 < 3/8 < 3/7

Answer:

A. 34

Step-by-step explanation:

Angle = 34°

The information will form a right angle triangle. Refer to the picture below for the diagram.

Using trigonometric ratio,

tan Ф = opposite / adjacent

tan Ф = 100 / 150

tan Ф = 0.66666666666

Ф = tan⁻¹ 0.66666666666

Ф = 33.6900672615

Ф ≈ 34°

Step-by-step explanation:

Slope is Rise over Run (y / x).

For 2 points, you would take the difference of y-coordinates and divide by the difference of x-coordinates.

(Y1 - Y2) / (X1 - X2)

Since both y-coordinates are the same (ten minus ten), your slope is zero (zero divided by anything is zero).

Answer:

6710.46x

Step-by-step explanation:

The solution is : the value of x is x = 9.75.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

You need to convert from mixed number to decimal number. To do this you can follow the steps shown below:

Step 1: You must divide the numerator of the fraction by the denominator of the fraction.

Step 2: Now you must add the quotient obtained to the Whole number part.

So, you get:

3 + 1/4

=3 + 0.25

= 3.25

Then, the scale image that maps "Figure a" onto "Figure b" is:

1: 3.25

Finally, in order to find the value of "x", you need to multiply the given length of the corresponding side of "Figure a" by .

Therefore, you get that the result is:

x = 3 * 3.25

or, x = 9.75

Hence, The solution is : the value of x is x = 9.75.

The measurement of the circumference of a circle is 21.3 ft.

The circumference is the perimeter of a circle. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment.

Here, given area of circle = 36 ft²

Area of Circle = πr²

           36 = 3.14 X r²

           r² = 11.46

          r = 3.38 ft.

Circumference of Circle = 2πr

                                       = 2 X 3.14 X 3.38

                                      = 21.25 ft. ≈ 21.3 feet

Thus, the measurement of the circumference of a circle is 21.3 ft.
