Answer:

An ordinary angle is a measure of the length subtended by a one-dimensional subset of the plane. For example, an angle of 60∘ is subtended from a point by a 16 portion of a circle centered at that point. The 16 arc that subtends the angle is a one-dimensional subset of the two-dimensional plane.

kaheart [24]

Answer:

$ 160

Step-by-step explanation:

ur getting 30% of the total money.....and ur getting $ 48

so..... 30% OF the total money IS 48

let x be the total money....and turn ur percent to a decimal.

" of " means multiply and " is " means equals

0.30x = 48

x = 48 / 0.30

x = 160 <=== total money

check it...

30% of 160 = 48

0.30(160) = 48

48 = 48 (correct)...it checks out

SW=2x+y, WC= x-2y, W is the midpoint of SC, and SC=20, find the values of x and y.

zysi [14]

Answer:

$x= 6$

$y = -2$

Step-by-step explanation:

Given

$SW = 2x + y$

$WC = x - 2y$

$SC = 20$

Required

Determine x and y

Since W is the midpoint;

$SW = WC = \frac{1}{2} * SC$

$SW = WC = \frac{1}{2} * 20$

$SW = WC = 10$

Substitute 10 for SW and WC

$2x + y = 10$ --- (1)

$x - 2y = 10$ ---- (2)

Make x the subject in (2)

$x = 10 + 2y$

Substitute $x = 10 + 2y$ in (1)

$2(10 + 2y) + y = 10$

$20 + 4y + y = 10$

$20 + 5y = 10$

Solve for 5y

$5y = 10 - 20$

$5y = -10$

Solve for y

$y = -10/5$

$y = -2$

Recall that $x = 10 + 2y$

$x = 10 + 2(-2)$

$x = 10 -4$

$x= 6$

Alina [70]

63 seconds is 90% of Niki's time for one lap. So, Niki's time for one lap is 63/0.9, which equals 70 seconds or 1 min. 10 seconds.

Subtract the $60 out of the total first

250 - 60 = 190

Divide this value by pay per sale:

190 / 4.50 = 42.2222

Thus, they must make 43 sales in order to meet the goal
