Help plzzz!! Find the slope through these pairs of points
Colt1911 [192]
We can use the formula y2-y1/x2-x1 to find the slope.

1. 2-(-15)/12-5 gives us 17/7. The slope is 17/7.

2. -5-(-20)/6-(-18) gives us 15/24. We can simplify this to 5/8. The slope is 5/8.

3. -19-(-19)/-17-(-18) is 0/1. The slope is 0.

4. -17-3/-11-(-1) is -20/-10. The slope is 2.

Andreas wants to estimate how many fish there are in a lake. One day he catches 20 fish,marks them,and returns them to the lake.
tensa zangetsu [6.8K]

Answer:

50

Step-by-step explanation:

The ratio of marked fish to caught fish is 4:10, we need to solve for x in 20:x, since 4 * 5 = 20, 10 * 5 = x so x = 50 fish.

An engineering firm designs a custom hexagonal screw for a computer board. A sketch of the top of the screw is below. To the nea
Sphinxa [80]

The area of the screw head is 93.5m².

<h3>How to calculate the area?</h3>

The area of the hexagon can be illustrated based on the formula:

A = 3✓3/2 × a²

Base = 12.

Height = 3.

Area of each triangle = 0.5 × 12 × 3 = 18

Area of the rectangle = 12 × 6 = 72

Therefore the area of the screw head will be:

= 3√3/2 × 72

= 93.5m²
