The minute hand of a clock is 1.4 centimeters long. How far does the tip of the minute hand travel in 40 minutes? (Round your answer to two decimal places.)

Answers

Answer 1

Answer:

2.93cm

Step-by-step explanation:

I have to admit, this stumped me but I got o work and here's what I have for you. Hope this helps. TIP: remember it is the minute hand not any other hand.

For this one you will have to find the circumference of the clock because as the min hand goes round and round, it will act as a radius and it will go in a circular motion.  

Formula will be π2r= 3.l4 * 2 * 1.4cm=8.792cm per every one revolution of the minute hand. Remembering that for the minute hand to revolve round the clock it has to cover 1 hr = 60min. For you to get the total circumference,

you'll have to take 8.792cm but since it is  per every one revolution of the minute hand, multiply it by 40/60min. The answer will be 2.93066cm before rounding off. After rounding off you will have 2.93cm. Quite lengthy but I assure you after practicing you'll have at your fingertips.

Write an equation in slope-intercept form of the line with slope 3/4 that contains the point (-4,1)

Answers

Answer:

y = 3/4x + 4

Step-by-step explanation:

to put it into slope intercept form, you need to find the y intercept or b becasue the slope intercept form is y = mx + b where b is the y intercetpt and m is the slope. To find b you insert the points you were given so 1 = -4(3/4) + b

which simplifies to 4 = b so then you can put in your slope and y intercept into slope intercept form

Answers

Answer:

For the first question, the slope is -3.

For the second question, the point is (-6,7)

Step-by-step explanation:

In point-slope form, to identify the slope, its the number that's before the parenthesis, which in this case, its -3.

In point-slope form, to identify the points, its the number that replaces y1 and x1, which in this case, its -7 and 6. However, in point-slope form, the numbers are the opposite of what they are. For an example, in this equation, -7 is negative, buts its point would actually be positive.

how do you solve for Y
problem #5

Answers

9514 1404 393

Answer:

  y = 26

Step-by-step explanation:

You have already correctly solved for x, so you know that ...

  m∠8 = 4(17)+10 = 78

Angle 12 is an alternate interior angle with respect to angle 8, so is congruent to angle 8.

  m∠12 = m∠8

  3y = 78

  y = 78/3 . . . . divide by the coefficient of y

  y = 26

6x9=54 11x8=88

Step-by-step explanation:

i dont get it hope it helps

Answer: x= -10

Step-by-step explanation:

Let's solve your equation step-by-step.

6x−9=8x+11

Step 1: Subtract 8x from both sides.

6x−9−8x=8x+11−8x

−2x−9=11

Step 2: Add 9 to both sides.

−2x−9+9=11+9

−2x=20

Step 3: Divide both sides by -2.

−2x /-2= 20/-2

x=−10

Answer:

x=−10

You must use 2 eggs to make 6 dozen cookies. How many eggs are needed to make 42 dozen
cookies? Use a proportion to solve.

Answers

Answer:

14 eggs

Step-by-step explanation:

Answer: It takes 14 eggs to make 42 dozen cookies

Step-by-step explanation: To solve using a proportion first start out with 2eggs/6cookies (They are in a dozen but 42 is also in a dozen so it cancels out). Now that you have 2/6 you now have to find the x in x/42. 42 divided by 6 is 7 so multiply 2 by 7 and you get: It takes 14 eggs to make 42 dozen cookies or 14/42. Hope this helps
