Answer:

Option C 60 degrees

Step-by-step explanation:

we know that

$m\angle RSM+m\angle NML=180^o$ ----> by supplementary angles (consecutive interior angles)

we have

$m\angle NML=120^o$

substitute

$m\angle RSM+120^o=180^o$

$m\angle RSM=180^o-120^o=60^o$

The sum of two numbers is −48 and their difference is 17. Find the numbers. pls asap

Hatshy [7]

Answer:

a = -15.5, b = -32.5

Step-by-step explanation:

Let's say the first number is a, and the second is b.

a + b = - 48

a - b = 17

If you add both equations, you get 2a = -31, because the

+b and -b cancel each other.

So you would get a + a = 2a, then -48 + 17 = -31

2a = -31

--- ---

2 2

Divide both sides by 2 to get a by itself.

a = -15.5

Then let's go to the next equation (a - b = 17)

Plug in a..

-15.5 - b = 17

+ 15.5 + 15.5

------

-b = 32.5

--- ------

-1 -1

b = -32.5

Hope this helps.

A cylinder has radius r and height h. A. How many times greater is the surface area of a cylinder when both dimensions are multi

Ierofanga [76]

Answer: A. Factor 2 => 4x greater

Factor 3 => 9x greater

Factor 5 => 25x greater

Step-by-step explanation: A. A cylinder is formed by 2 circles and a rectangle in the middle. That's why surface area is given by circumference of a circle, which is the length of the rectangle times height of the rectangle, i.e.:

A = 2.π.r.h

A cylinder of radius r and height h has area:

$A_{1}$ = 2πrh

If multiply both dimensions by a factor of 2:

$A_{2}$ = 2.π.2r.2h

$A_{2}$ = 8πrh

Comparing $A_{1}$ to $A_{2}$ :

$\frac{A_{2}}{A_{1}}$ = $\frac{8.\pi.rh}{2.\pi.rh}$ = 4

Doubling radius and height creates a surface area of a cylinder 4 times greater.

By factor 3:

$A_{3} = 2.\pi.3r.3h$

$A_{3} = 18.\pi.r.h$

Comparing areas:

$\frac{A_{3}}{A_{1}}$ = $\frac{18.\pi.r.h}{2.\pi.r.h}$ = 9

Multiplying by 3, gives an area 9 times bigger.

By factor 5:

$A_{5} = 2.\pi.5r.5h$

$A_{5} = 50.\pi.r.h$

Comparing:

$\frac{A_{5}}{A_{1}}$ = $\frac{50.\pi.r.h}{2.\pi.r.h}$ = 25

The new area is 25 times greater.

B. By analysing how many times greater and the factor that the dimensions are multiplied, you can notice the increase in area is factor². For example, when multiplied by a factor of 2, the new area is 4 times greater.
