4 0

Answer:

Step-by-step explanation:

x = first number, y = second number

4x - 3y = 12

2x + 3y = 6

------------------add

6x = 18

x = 18/6

x = 3

4x - 3y = 12

4(3) - 3y = 12

12 - 3y = 12

-3y = 12 - 12

-3y = 0

y = 0

solution : (3,0)

andreyandreev [35.5K]

Answer:

$600 in commission for the week paying 15% on up to $1000 daily

Step-by-step explanation:

To find the sales commission, multiply the percentage 15% as 0.15 against each sales up to $1000.

Monday - 0.15 (800) = $120

Tuesday - 0.15 (600) = $90

Wednesday - 0.15 (1000) = $150

Thursday - 0.15 (800) = $120

Friday - 0.15 (800) = $120

In total that's, $600 in commission.

Answer:

19 cm

Step-by-step explanation:

Given :

Volume, V = 205 to the √3 = 205^√3

Height, h = 8.9

radius, r

Volume of cylinder:

V = πr²h

205 to the square root of 3 10094.275

company is designing a new cylindrical water bottle. The volume of the bottle will be 205 cm to the square root of 3 cm. The height of the water bottle is 8.9 cm. What is the radius of the water​ bottle?

10094.275 = π * r² * 8.9

10094.275 = 3.14 * 8.9 * r²

10094.275 = 27.946r²

r² = 10094.275 / 27.946

r² = 361.20643

r = √361.20643

r = 19 cm
