Answer:

Two semi circles would equal one circle.

The perimeter of a circle is PI x diameter.

The diameter of the circle is shown as 56 m

The perimeter of the 2 ends = 56 x 3.14 = 175.84

The length of the inside of the track is given as 130 m, and there are 2 sides so 130 + 130 = 260 m.

Total perimeter = 260 + 175.84 = 435.84 m.

Answer:

The first one answer is for a different equation. I have this test and got to FLVS. This is the right answer.

Step-by-step explanation:

SInce the length is 150 on one side you multiply it twice. 150*2=300

Then you find the circumference which is 46.

Then, you solve 80+46(3.14)

You multiply 46*3.14= 144.44.

Then you add 144.44 to 300 which gets you 444.44

Through: (1,-1), parallel to y = -3

zheka24 [161]

Answer:

The equation of a line parallel to the line and passing through (1, -1) is:

$y=-3x+2$

Step-by-step explanation:

Given the line

y = -3

We know that the slope-intercept form of the line equation is

$y=mx+b$

where m is the slope and b is the y-intercept

Thus, the slope of the equation y=-3 will be m = -3

We know that the parallel lines have the same slopes.

Thus, the slope of the parallel line will also be -3.

Thus, using the point-slope form to find the line equation is

$y-y_1=m\left(x-x_1\right)$

substituting the values m = -3 and the point (1, -1)

y-(-1) = -3(x-1)

y+1 = -3x+3

y=-3x+3-1

y=-3x+2

Thus, the equation of a line parallel to line and passing through (1, -1) is:

$y=-3x+2$

Which equation represents a line that passes through (4, 1/3,) and has a slope of 3/4 ?

Aleks [24]

Answer:

second option

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = $\frac{3}{4}$ and (a, b) = (4, $\frac{1}{3}$ ) , thus

y - $\frac{1}{3}$ = $\frac{3}{4}$ (x - 4)
