Answer:

17pi/15

Step-by-step explanation:

s = r *theta where r is the radius and theta is the central angle in radians

Convert 51 to radians

51 * pi/180 = 51pi/180

s = 4 * 51pi/180

= 17pi/15

Write an equation parallel to the line determined by the points (15, -6) and (-3, 13), through: (4, 2)

gulaghasi [49]

Answer:

The answer is

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

That's

Slope of the through points

(15, -6) and (-3, 13) is

Since the lines are parallel their slope are also the same

So slope of parallel line = - 19/18

Equation of the line using point (4,2) and slope -19/18 is

We have the final answer as

Hope this helps you

What is the sum of the first 50 terms of the series 2 + 17 + 32 + 47+ ...?

Alex

Answer:

$\huge\boxed{18,475}$

Step-by-step explanation:

The terms of this sum make the arithmetic sequence.

The fomula of a sum of <em>n</em> terms of an arithmetic sequence:

$S_n=\dfrac{[2a_1+(n-1)d]\cdot n}{2}$

We have

$a_1=2\\d=17-2=32-12=47-32=15\\n=50$

Substitute:

$S_{50}=\dfrac{[2\cdot2+(50-1)\cdot15]\cdot50}{2}=(4+49\cdot15)\cdot25=(4+735)\cdot25\\\\=739\cdot25=18,475$

If Keira spends $45 on petrol, 1/ 9 of the money on other items and 1 /5 of the money on clothes. How much money does she spend

gogolik [260]

Answer:

The money Keira spent on food is $31.

Step-by-step explanation:

Total money spent by Keira = $45

Things Keira spent money on:

1. Clothing

2. Food

3. Other items

Money spent on Clothing = 1/5 of total money

= 1/5 x $45

Money spent on Clothing = $9

Money spent on Other Items = 1/9 of total money

= 1/9 x $45

Money spent on Other Items = $5

Money spent of on Food = Money spent - (Money spent on clothing + other items)

Money spent on food = 45 - (9+5)

= 45 - 14

Money spent on food = $31

kondor19780726 [428]

Hello there!
So the equation I would use for this word problem is 3(s+5)=45.
3s+15=45
-15 -15
__________
3s=30
Divide 3 from both sides.
s ends up equaling 1.
Each stuffed animal elephant cost $10
