Answer:

(1,2) is a solution to both equations

Step-by-step explanation:

To determine if (1,2) is a solution to both equations, substitute into the equation and see if it is true

2x+y =4

2(1) + 2 =4

2+2 =4

4=4

true

y =3x-1

2 = 3(1) -1

2 =3-1

2=2

true

Since both statements are true

(1,2) is a solution to both equations

Find the volume of a cylinder with height 14.7 cm and diameter 10.5 cm.

velikii [3]

Hello!

The volume of a cylinder is found by using the formula: V = πr²h.

The problem has given us the height of the cylinder, which is 14.7 centimeters, and the diameter which is 10.5 centimeters. The volume of a cylinder requires the radius, so therefore, to find the radius, divide the diameter by half, and that will give the radius.

R = 10.5 / 2

R = 5.25 centimeters

With that radius and the height, we can find the volume of the cylinder.

V = π(5.25)²(14.7)

V = 27.5625(14.7)π

V = 405.17π, 1272.23 (multiplied by 3.14), 1272.88 (multiplied by π)

Therefore, the volume of this cylinder is 1272.88 centimeters³.

Clyde is putting a fence around a rose bush in his garden . The measures of two sides that meet at a corner are 27 feet and 34 f

Nonamiya [84]

Answer:

The length of the diagonal have to be 43.4 feet

Step-by-step explanation:

we know that

For the corner to be a right angle, the length of the diagonal must satisfy the Pythagorean Theorem

Let

x ----> the length of the diagonal

$x^2=27^2+34^2$

$x^2=1,885\\x=43.4\ ft$

therefore

The length of the diagonal have to be 43.4 feet
