# The field at Harrington Middle School is 70 yards long and has a diagonal measure of 84 yards. What is the perimeter of the triangular field?

200.43 yds

Step-by-step explanation:

84 x 84 = 7,056

70 x 70 = 4,900

7,056 - 4,900 = 2,156

= 46.43

84 + 70 + 46.43 = 200.43 yds

6 sisters share 4 sandwiches equally what's the fraction

If you would like to know how many sandwiches will each sister get, you can calculate this using the following steps:

6 sisters ... 4 sandwiches
1 girl ... x sandwiches = ?

6 * x = 4 * 1
6 * x = 4      /6
x = 4/6
x = 2/3

The correct result would be 2/3 of a sandwich.
the answer is 2/3 hope i helped

a scale drawing of a rectangular park is 5 inches wide and 7 inches long. the actual park is 280 yards long. whats the area of the actual park, in square yards?

The actual area of the park in square yards from the given scale is;

Actual area of park = 56000 yds²

We are told that;

There is a scale drawing of a rectangular park with dimensions;

Width = 5 inches

Length = 7 inches

Now, we are told that the Actual length of the park is 280 yards.

Since the length on the scale drawing is 7 inches, then it means that;

7 inches represents 280 yards

Thus, 1 inch will represent; 280/7 = 40 yards

Thus, actual width = 5 × 40

Actual width = 200 yards

Formula for area of rectangle is;

Area of rectangle = Length × width

Thus;

Actual area of rectangle = actual length × actual width

Actual area of rectangle = 280 × 200

Actual area of rectangle = 56000 yds²

Area of the actual park is 56000 square yards.

Step-by-step explanation:

A scale drawing of a rectangular park has dimensions as 5 inches width and 7 inches length.

Actual length of the park has been given as 280 yards.

So scale factor used in the drawing is 7 inches = 280 yards

Or 1 inch = 40 yards

Since width of the rectangular park is = 5 inch

So actual width of the park will be = 5×40 = 200 yards

Now we can calculate the area of the park.

Actual area of the park = Length × Width

= 280×200

= 56000 yards²

Therefore, area of the actual park is 56000 square yards.

Find the gradient of the line segment between the points (-8,6) and (-10,14)

The required gradient of the line between the points (-8,6) and (-10,14) is -4.

### What is the slope of the line?

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The gradient of the line segment between points (-8,6) and (-10,14) is given as,

The gradient of the line = slope of the line,
m = (y₂ - y₁) /  (x₂ - x₁)

Substitute the value in the above equation,
m = 14- 6 / -10 + 8
m = 8 / -2
m = -4

Thus, the required gradient of the line between the points (-8,6) and (-10,14) is -4.
