If you are learning about how to calculate the mean of something, than to estimate the height just find the mean, all the peaks added together, and divided by the amount of numbers (27 + 18 + 12 = 57 ... 57 divided by 3 = 19. Your mean is 19)

The standard tip in a restaurant is 15% of the bill before tax. Many people in California find the tip by doubling the sales tax

cricket20 [7]

To answer this you could do a couple things. 1. Actually calculate both tips and then subtract them. Here is the math ( assuming it is $60, not 60% that you mean). a. 0.15 x 60 = $9. b. 0.0825 x 2 x 60=$9.90. c. 9.90-9.00= $0.90 difference.

The other strategy would be to find the difference on the percents and then multiply by $60. a. 8.25%x2=16.5%-15%. Difference of 1.5%. b. 0.015 x $60=$0.90.

Find degree measures of marked angles in fig 5.47

Sati [7]

Answer:

50+P=125 exterior angle of the triangle is equal to the sum of two opposite interior angle

P=125-50=75°

q+125=180 linear pair

q=180-125=55°

r=q=55° vertically opposite angle

s+85=125 exterior angle of the triangle is equal to the sum of two opposite interior angle

s=125-85=40°

s+t=180 linear pair

t=180-40=140°

u=s=40° vertically opposite angle

w=65° vertically opposite angle

v+u+w=180 sum of interior angle of the triangle is 180

v+40+65=180

v=180-105=75°

x+65=180 linear pair

x=180-65=115°
