Answer:

Y=-x-1

explanation:

(1,-2)

(2,-3)

And use the slope formula, y2-y1/x2-x1

Where y2=-3

Y1=-2

X1=1

X2=2

So

-3+2/2-1=-1

So the slope is -1 and y intercept is -1

Let’s plug those values in:

Y=-x-1

The length of the walkway is 24 ft, and you will need 24 stones to cover it.

The length of the walkway will be equivalent to the hypotenuse of a right triangle with cathetus of 23ft and 18ft, so we can use the Pythagorean theorem to get it:

L^2  =(23fy)^2 + (18ft)^2

L = √( (23fy)^2 + (18ft)^2 ) = 23.77ft

The walkway is 23.77 ft long.

Rounding to the nearest foot, the length is 24 ft.

b) If each stone covers 1 ft, then you will need 24 stones.

Step-by-step explanation: Suzie says that [tex]\frac{1}{2}[/tex], which is half of a whole, is equal to only [tex]\frac{1}{4}[/tex] of the unknown number. This means that to find the value of the unknown number, you need to multiply [tex]\frac{1}{2}[/tex] by 4 so that it equals to [tex]\frac{4}{4}[/tex] of the mystery number.

Simply put, multiply [tex]\frac{1}{2}[/tex] by 4. Then reduce for the answer, and this gives us these equations.

[tex]x=4(\frac{1}{2} )[/tex]

[tex]x=\frac{4}{2}[/tex]

[tex]x=2[/tex]

Step-by-step explanation: Angle subtended by an arc at the centre is twice of the angle subtended at any point on the circle . And in the given diagram, angle subtended on the circle by arc XZ=60 degree . So arc XZ =2*60=120. Therefore measurement of arc xyz=360-120=240 degree.

The measurement of arc xyz is 240 degrees.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Angle subtended by an arc at the centre is twice of the angle subtended at any point on the circle .

In the given diagram, angle subtended on the circle by arc XZ=60 degree .

So arc XZ =2 times of 60

=2×60

=120.

The measurement of arc xyz=360-120=240 degree.

Hence, the measurement of arc xyz is 240 degrees.

x = total amount split between Adam and Tom.

since we know the total amount split between both in a 18 : 17 ratio is "x", let's divide "x" by (18 + 17) and distribute accordingly to get the amount of each.
