Answer:

62.38

Step-by-step explanation:

1. decimal with 2 decimal places (.XX)

2. less than 100 (XX.XX)

from here, let's assign variables to our number: AB.CD

C = 1,3,5

A = 3B

D = A + B (must be less than 9)

A = 2C

with these limitations, we can extrapolate that A must be divisible by both 2 and 3. what number less than 9 has these factors? 6

A = 6

this means that B = 2 and C = 3

and, now with A and B, D = 8

so, putting them all together: AB.CD = 62.38

3. In the diagram of circle 0, two tangents have been drawn from exterior point P to the circle at points A and B. (a) If mAB =1

Maru [420]

Answer:

Step-by-step explanation:

Given:

mAB =105

The minor arc given mAB is 105. Subtract that from 360 to get the measure of the major arc mACB

<=> mACB = 360 - 105 = 255

As we know, the measure of an angle formed by two tangents intersesting outside the circle can be found by one haft of the difference between the mearsure of two intercepted arcs

=> the measure of ∠P is:

= (mACB - mAB)/ 2

= (255 - 105)/2

= 75

Neil has been running a tutoring business since 2005. He charges a monthly fee for weekly tutoring sessions and a phone help lin

emmainna [20.7K]

Answer:

Part A. Rate of change $ 50

The initial value of Neil's business is $ 1,200

Part B. x = 1200 + 50y

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Year Annual Tutoring Fee

2005 $ 1,200

2008 $ 1,350

2. What is the rate of change and initial value for Neil’s business? How do you know?

Rate of change = (Annual Tutoring Fee in 2008 - Annual Tutoring Fee in 2005)/(2008 - 2005)

Replacing with the values we have:

Rate of change = (1,350 - 1,200)/3

Rate of change = 150/3 = $ 50

The initial value of Neil's business is $ 1,200

3. Write an equation in slope-intercept form to represent the fees that Neil charges each year.

Let x to represent the the fees that Neil charges annually and y to represent the number of years after 2005, we have:

x = 1200 + 50y

Seven less than a number is twenty (as an equation)

3241004551 [841]

You're expression is correct if it's asking for a number that is less than 7. But if the problem is asking for some number less than seven as in seven less some number, then it's 7-n. For example: 4 less than 7 is 7-4.

Hope this helps!

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 27 ft.

rosijanka [135]

Answer:

Step-by-step explanation:

for the cylinder

27π = πr²h = πr²(2r) = 2πr³

for the sphere

V = (4/3)πr² = (2/3)(2πr³) = (2/3)27π
