Solve the system 3x – 2y = 1 2x + 2y = 4

Mathematics

1 answer:

natulia [17]3 years ago

3 0

Answer:

x = 1, y = 1

Step-by-step explanation:

Given the 2 equations

3x - 2y = 1 → (1)

2x + 2y = 4 → (2)

Adding (1) and (2) term by term, eliminates the term in y

5x = 5 ( divide both sides by 5 )

x = 1

Substitute x = 1 into (2) for corresponding value of y

(2 × 1) + 2y = 4

2 + 2y = 4 ( subtract 2 from both sides )

2y = 2 ( divide both sides by 2 )

y = 1

A cylinder has a volume of 900 cu cm and a base with a diameter of 14 cm. Find the height of the cylinder to two decimal places.

gizmo_the_mogwai [7]

Answer:

The height of the cylinder is 5.85 cm.

Step-by-step explanation:

Given that,

Volume of cylinder, $V=900\ cm^3$

Diameter of the base of cylinder, d = 14 cm

Radius, r = 7 cm

We need to find the height of the cylinder. The volume of cylinder is given by :

$V=\pi r^2h$

h is height of cylinder

$h=\dfrac{V}{\pi r^2}$

$h=\dfrac{900}{\dfrac{22}{7}\times (7)^2}\\\\h=5.85\ cm$

So, the height of the cylinder is 5.85 cm.
