The ratio of boys to girls in a science class is 8:7. If there are 14 girls, how many boys are in the class?

16

Step-by-step explanation: If the ratio is 8 boys for every 7 girls and there are 14 girls, that means there are 2x the amount of girls in the ratio. 7 -> 14. This means that there are also 2x as many boys. 8 -> 16.

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3
