16 factory workers made 40 pieces in a certain amount of time.
qwelly [4]

a) The quantities vary directly

b) The constant of variation is 2.5

Step-by-step explanation:

Lets us revise the direct and inverse variation

  • If y varies x directly, then y = kx, that means the ratio between them is constant ( \frac{y}{x}=k ) , they increased together and decreased together, k is the constant of variation
  • If y varies x inversely, then yx = k, that means when x increased y must be decrease ( y=\frac{k}{x} ) k is the constant of variation

∵ 16 factory workers made 40 pieces in a certain amount of time

- If the number of worker increased, then the number of pieces

   increased in the same certain time, if the number of worker

   decreased, then the number of pieces also decrease in the

   same certain time

∴ The the number of workers and the number of pieces produce

   vary directly

∴ Number of pieces produced = k × number of worker

a) The quantities vary directly

∵ The number of worker = 16

∵ The number of pieces produced = 40

- Substitute these values in the equation of variation above

∴ 40 = k × 16

- Divide both sides by 16

∴ k = 2.5

b) The constant of variation is 2.5

It is known that x+y=10 and that x=z show that z+y=10
morpeh [17]
Known that,

x = z

Also known that,

x + y = 10

Substituting value of x,

z + y = 10

Hence, proved.

CAN SOMEONE HELP ME WITH WIYH THIS ?????
fomenos

Answer:

x = 14

Angle B = 121°

Angle C is 59°

Step-by-step explanation:

First we'll find x, then we'll find Angle B (by substituting in x), then we'll find Angle C (bc Angle B and C are supplementary--that us, they add up to 180°)

10x-19 = 7x+23 subtract 7x

3x-19 = 23 add 19

3x = 42 divide by 3

x = 14

Angle B is 10x-19, and if x=14, then its 10(14)-19

Angle B is 140-19

which is 121°

Angle B = 121°

Angle B and Angle C add up to 180°

121° + c = 180°

c = 180-121

Angle C is 59°

Just number 12 please and thank you....please get done asap
Marysya12 [62]
The interest rate on her account would be 38.4%.

If we use the simple interest formula I=PrT, the principle (P) would be 6000. Assuming that it is based on annual interest, the time (t) would be 1/12. Then, you multiply 6000 by 1/12 to get 500. Finally you divide 192/500 and then multiply by 100.


If the time is based on monthly payments, then do the same thing, except multiply 6000 by 1
