The second hand of a clock is 10 inches long. Find the linear velocity of the tip of the second hand
Answer:
10 inches/hour
Step-by-step explanation:
The tip moves clockwise in a circle of radius 10 inches. The linear velocity is v = rω, where r is the radius and ω the angular velocity.
This comes out to v = (10 inches)(1 revolution per hour) = 10 inches/hour

Answer:
x = -4 (and btw that is so cuteee)
Step-by-step explanation:
Points: (-4,-1) and (-4,-5)
m = y2 - y1/x2 - x1
m = (-5) - (-1)/(-4) - (-4)
m = -5 + 1/-4 + 4
m = -4/0

A salesman's commission is directly proportional to his total sales. If the commission is $100 for $1000 in sales, find the commission for $1750 in sales.
The commission of the salesmen with the given ratio will be $175.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
The commission is $100 for $1000 in sales.
Ratio of commission to sales = 100/1000 = 0.1
With the same ratio,
Commission/1750 = 0.1
Commission = 1750 x 0.1 = $175
Hence "The commission of the salesmen with the given ratio will be $175".

write a two-step equation that can be solved using the addition property of equality and the division property of equality.
Answer:
8x-14=26
Step-by-step explanation:
To solve this equation you first have to add 14 to both sides to cancel the -14 from the left side. Then you have to divide both sides by 8 to cancel out the 8 in front of the x and to get x alone. Then you have your answer. The answer to 8x-14=26 is x=5.

What is the volume of the regular pyramid below?
OA. 108 units3
OB. 648 units3
Oc. 144 units3
OD. 216 units
Answer:
D. 216
Step-by-step explanation:
What I did was I multiply 9x9x8 and got 648. I then divide 648 by 3 and got 216. I would appreciate it if you can mark this the brainliest if you can.
The volume of the regular pyramid is V = 216 units³
What is the volume of a pyramid?The volume of a pyramid, is the product of the area of its base with the height of the pyramid, and divide by 3. We express this product with the formula V = ( 1/3) ×B×h, where B is the area of the base of the pyramid, and h is its height.
Volume of Pyramid = ( 1/3 )a²H
Given data ,
Let the volume of the pyramid be represented as V
Now , the equation will be
Let the height of the pyramid be H = 8 units
Let the side length of the pyramid a = 9 units
Now , Volume of Pyramid = ( 1/3 )a²H
On simplifying , we get
The volume of pyramid V = ( 1/3 ) ( 9 )² ( 8 )
The volume of pyramid V = ( 27 ) ( 8 )
The volume of pyramid V = 216 units³
Hence , the volume of the pyramid is 216 units³

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.
1. Change the equation to slope intercept form. Identify the slope and y- intercept of the equation. Be sure to show all your work.
2x + 3y= 1470
2x + 3y -2 = 1470 subtract 2x from both sides
3y= 1470 -2x simplify
3y/3= 1470/3 -2x/3 divide both sides by 3
y= -2/3x +490 simplify
-⅔ is the slope and 490 is the y- intercept
2. Describe how you would graph this line using the slope- intercept method. Be sure to write in full sentences.
Start at 490 on the y axis. After that you would use rise over run, down 2 units and right three. Do this until you reach the end of the graph, then go oppisite; up 2 left 3
3. Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.

sec 16° cosec 74° - cot 74° tan 16°
Answer:
1.
Step-by-step explanation:
sec 16° cosec 74° - cot 74° tan 16°
= 1/ cos 16 * 1/ sin 74 - 1/tan 74 * tan16
= 1/ cos16 sin 74 - cos74/ sin74 * sin 16 / cos 16
Now cos 16 = sin 74 and sin 16 = cos 74 (supplementary angles) so:
= 1 / cos^2 16 - sin 16/cos 16 * sin 16 / cos 16
=( 1 - sin ^2 16 )/ cos^2 16
= cos^2 16 / cos^2 16

Jesse practices the trumpet for a total of 165 minutes during the first week of school. He practices for 245 minutes during the second week. A. Estimate the total amount of time Jesse practices by rounding to the nearest 10 minutes.
Answer:
410 minutes
Step-by-step explanation:
Given that:
Time for which Jesse practices trumpet in the first week = 165 minutes
Time for which Jesse practices trumpet in the second week = 245 minutes
To find:
The total amount of time rounded to the nearest 10 minutes.
Solution:
To find the total amount of time for which Jesse practices, we need to add the time taken for practice in the first week and the time taken for practice in the second week.
Therefore, total time taken = 165 + 245 = 410 minutes
It is already rounded off to the nearest 10 minutes.
Therefore, the answer is:
Total amount of time for which Jesse practices = 410 minutes
