What is the length of the missing leg in the triangle below?

We need to know the known side lengths to answer the question but I'll do my best to help you answer the question.

Step-by-step explanation:

Square the hypotenuse and subtract the answer by the square of the known leg. The square root of the answer will be the missing leg.

Pythagorean theorem is a²+b²=c² to find the hypotenuse.

But in this case, sense you are trying to find the length of a leg, it is c²-a²=b² (c is the hypotenuse length and a is the known leg length).

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
