Answer:

15 inches

Step-by-step explanation:

We are given;

Linear velocity; V = 240 in/min

ω = 16 rev/min

Now, in circular motion, formula for linear velocity is;

V = ωr

Where ω is angular velocity and r is radius which is the distance between the object and the fixed point.

Thus;

240 = 16r

r = 240/16

r = 15 inches

Answer:

1050

Step-by-step explanation:

1. divide using long division

put 2 outside and the 2100 inside

then from there 2 goes into 2 once so put that on top. Next 2 cant go into one so put a zero above the one. After that 2 goes into 10 5 times so put a 5 above the first zero in 2100. Lastly 2 goes into zero 0 times so put a zero above the second zero.

Answer:

It would be a perpendicular or anything on a y- axis

Step-by-step explanation:

because in this case the perpendicular would be the slope of a vertical line which would be undefined.

Answer:

[tex]\boxed {x = \frac{17}{10}}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]3(5 - x) = 7x - 2[/tex]

-Use Distributive Property:

[tex]3(5 - x) = 7x - 2[/tex]

[tex]15 - 3x = 7x - 2[/tex]

-Take [tex]7x[/tex] and subtract it from [tex]-3x[/tex]:

[tex]15 - 3x - 7x = 7x - 7x - 2[/tex]

[tex]15 - 10x = -2[/tex]

-Subtract [tex]15[/tex] to both sides:

[tex]15 - 15 - 10x = -2 - 15[/tex]

[tex]-10x = -17[/tex]

-Divide bot sides by [tex]-10[/tex]:

[tex]\frac{-10x}{-10} = \frac{-17}{-10}[/tex]

[tex]\boxed {x = \frac{17}{10}}[/tex]

So, the value of [tex]x[/tex] is [tex]\frac{17}{10}[/tex].

Answer:

1h 22m

Step-by-step explanation:

Because 1/4 of an hour is 15m and 15X5=75 or 1h and 15m

then 1/3 of a lap would just be 33% of 15m which is 6.6m or round that up to 7 so 1h and 15m + 7m= 1h and 22m

hope that helped.

Answer:

1 ÷ 6

Step-by-step explanation:

Let us assume the probability of the red marble for selecting it first time be x

And, it is to be done 3 times

that means

= 1 ÷ x × 1 ÷ x × 1 ÷ x

This equivalent to = 1 ÷ 216

And the 216 could be calculated by multiplied 6 3 times i.e.

= 6 × 6 × 6

= 216

So, the probability for selecting it for a first time is

= 1 ÷ 6

Answer:

14. Three points tat are not collinear

Three points that are not colinear consist of a line and a third point, therefore, joining all three points form a flat figure having a length and a width which is a two-dimensional flat figure or a plane

15. A line and a point not lying on the line

Like the example above, the joining of the points results in a two dimensional figure having a length and a width also known as a planar surface

16. Two lines which intersect at a point

Given two lines that intersect at a point, joining the other end point of the two lines results in the forming of a flat figure, that can be described in two dimensions also known as a planar surface or plane

Step-by-step explanation:

A plane in mathematics is a flat surface that has only two dimensions and extends infinitely in all directions

1. the three main functions of trigonometry are;

The sine

The cosine

The tangent

2. The hypotenuse is opposite the right angle. The opposite side is opposite the reference angle. The adjacent side is next to the reference angle

3. The opposite and adjacent are the sides which are interchangeable depending on the reference angle.

4. SOHCAHTOA

SOH means ;

Sine = opposite/hypotenuse

CAH;

cosine = Adjacent/Hypotenuse

TOA;

Tangent = opposite/adjacent

Answer:

[tex]d = \sqrt{10}[/tex]

Step-by-step explanation:

Distance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Simply plug in the 2 coordinates into the distance formula to find distance d:

[tex]d = \sqrt{(-2-(-5))^2+(-1-0)^2}[/tex]

[tex]d = \sqrt{(-2+5)^2+(-1)^2}[/tex]

[tex]d = \sqrt{(3)^2+1}[/tex]

[tex]d = \sqrt{9+1}[/tex]

[tex]d = \sqrt{10}[/tex]

Answer:

The interest on the savings account is $46.47

Step-by-step explanation:

Here, we want to know the interest earned on the savings account.

The difference between the new and previous balance will be; 12,098.12 - 9,053.20 = $3,044.92

The difference between amount deposited and amount withdrawn is 3,298.45 - 300 = 2,998.45

This is the amount that is supposed to be on the account without interest

So the interest earned would be; 3044.92 - 2,998.45 = $46.47

The values of A = 1, B = 0, and C = 9 would be Ax + By = C represent the beam of light.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

A flashlight shines straight up into the sky, 9 ft to the right of a tent located at the origin.

Given that the direction must be vertical, it should appear to have a consistent or constant x-coordinate.

Here Ax + By = C represents the beam of light.

So the required equation for a line is:

⇒ x = 9

Comparing the given equation, we get

Ax + By = C

Here A = 1, B = 0, and C = 9

Therefore, the values of A = 1, B = 0, and C = 9 would be Ax + By = C represent the beam of light.

Step-by-step explanation:

Answer: E) Mean will decrease, standard deviation will decrease

Step-by-step explanation:

Initial mean = 81

Initial standard deviation = 9

New score = 78

Taking a look at the initial mean(averahe) score, which is 81 and the new score to be added to the initial scores, the initial average is greater than the new score. Hence, this will result in a decrease in the new mean score after adding the new score of 78.

Also, taking a look at the standard deviation which is 9, we can conclude that the variability in initial scores from the mean scores is high. However, the new score of 78 and the initial mean are very close, and tend to low variation. Hence, adding the new score will lead to a decrease in variability and hence a decrease in the value of standard deviation.
