The airplane that cruises 1 kilometer in 1/12 of a minute has a speed of 12 km/min

The formula and procedure we will use to solve this problem is:

v = x/t

Where:

Information about the problem:

Applying the velocity formula, we get:

v = 1 km/ (1/12 min)

v = (1 km * 12) / 1 min

v = 12 km/ 1 min

v = 12 km/min

It is a physical quantity that indicates the displacement of a mobile per unit of time, it is expressed in units of distance per time, for example (miles/h, km/h).

To find the average rate of change from two points: [a, b] we generally use the slope equation, which can be represented as: [tex]\frac{f(a)-f(b)}{a-b}[/tex]

So here let's first calculate f(3) and f(5)

[tex]f(3)=(3)^2-5(3)+14\\f(3)=8\\\\f(5)=(5)^2-5(5)+14\\f(5)=14[/tex]

Now let's plug these values into the equation: [tex]\frac{f(5)-f(3)}{5-3}[/tex]

To get the equation: [tex]\Longrightarrow \frac{14-8}{5-3}=\frac{6}{2}=3[/tex]

The total number of muffins were 40 and the equation which represnts the given scenarion is (7/10)x = 28.

Let the total number of muffins be x.

According to the given question.

The number of muffins which blew away by wind = 28

And 28 muffins are the 7/10 part of the total muffins.

Therefore, the linear equation in one variable which represents the above scenario is given by

(7/10)   ×  x = 28

⇒ 7x = 280        (multiplying both the sides by 10)

⇒ x = 280/7          (dividing both the sides by 7)

⇒ x = 40

Hence, the total number of muffins were 40 and the equation which represnts the given scenarion is (7/10)x = 28.

The slope of the line = rise/run = 2/3.

To determine the slope of a line, we can find the ratio of the rise of the line to that of its run.

Therefore, slope (m) of a line = rise/run.

Rise = vertical distance across the line

Run = horizontal distance across the line

In the graph given, we have:

Rise is the blue line = 6 units

Run is the red line = 9 units

Slope of the line (m) = 6 units/9 units

Slope of the line (m) = 2/3

Therefore, In simplest form, the slope of the line = rise/run = 2/3.

Answer:

Step-by-step explanation:

P, perimeter of triangle = a + b + c

We're given P = 140 and it is an isosceles triangle.

We can change P to be 2a + b since 2 sides are equal in an isosceles

So, 140 = 2a + b

One side is 3x longer than the other. The equal sides in the triangle can not be 3x longer than each other since it is equal.

And the isosceles sides are longer than the 1 base side.

So if a = our isosceles sides, and b is our base side, than a is 3x our base side which can be written as a = 3b

Now, 140 = 2(3b) + b, and we can now solve

140 = 6b + b => 140 = 7b

20 = b

Our base length is 20.

Answer:

66.8 inches

Step-by-step explanation:

The mean height of 16 students is 67.0"

Total height of 16 students = 67 x 16 = 1,072"

When Danielle walks into the class an additional height of 63.6" is added to the total and the new total becomes 1072 + 63.6 = 1135.6"

Since there are now 17 students, mean = 1135.6/17 = 66.8"

The null hypothesis is [tex]H_0:\mu=3[/tex] and the alternative hypothesis is [tex]H_1:\mu > 3[/tex]

Formulation of null and alternative hypothesis are considered as the first step of a statistical procedure. The whole procedure, then, continues on testing whether to accept or reject these hypotheses.

Null Hypothesis is the actual hypothesis which is tested. Alternative hypothesis, as its name suggests, is the hypothesis accepted when the null hypothesis is rejected in the test carried out.

Here the sociologist is carrying out the test on the mean number of cars, [tex]\mu[/tex].

For you and your sister to reach bottom at the same time, the large Ferris wheel has to take 7 revolutions and the small Ferris wheel has to take 10 revolutions.

Time taken by the large Ferris wheel to complete 1 revolution = 10 seconds.

Time taken by the small Ferris wheel to complete 1 revolution = 7 seconds.

For them to reach bottom at the same time, we need to calculate their least common multiple.

LCM of 10 and 7 will be :

LCM = 10 × 7 = 70 seconds.

Revolutions taken by large Ferris wheel will be = 70 / 10 = 7 revolutions.

Revolutions taken by small Ferris wheel will be 70 / 7 = 10 revolutions.

Answer:

x = 5

Step-by-step explanation:

Because an isosceles triangle's angles will always add up to 180, it's quite simple plugging in angle J into a formula to find our answer.

Before we begin, recall that the bottom two angles of an isosceles triangle are equal to the other. Thus:

Unknown angle (H) = 14x+1

So...

38 + 14x + 1 + 14 x + 1 = 180

40 + 28x = 180
-40             -40
28x = 180

28x/28 = 180/28

We get:
x = 5

Answer:

[tex]x = 5[/tex]

Step-by-step explanation:

Note that:

Calculating For the Value Of X

(14x + 1)° + (14x +1)° +38° = 180°

14x + 1 + 14x + 1 + 38 = 180°

28x + 2 + 38 = 180°

28x + 40 = 180°

28x = 180 - 40

28x = 140

x =5

Therefore the value of x is 5
