Answer:
43
Step-by-step explanation:
BE=EC=6 BC=12
AC=2DE=15
AB=2FE=16
12+16+15=43
1. find the speed of a car
the distance is 124 miles and the time is 2 hours
the speed is defined as distance / time, therefore
speed = 124/2 = 62 miles/hour
that is the speed
2.find the time from equation time = distance/speed, when the distance is 395 miles and the speed is 79 miles/hour, then
time = 395 miles / 79 miles/hour = 395/79
time = 5 hours
D. 10
m<3 = 80 - (10) = 70
m<7 = 90 - (20) = 70
Answer:
Option B). 10 cm
Step-by-step explanation:
Distance between center and the focus of an ellipse is given by the formula,
c² = a² - b²
where, a = length of the major axis
b = length of the minor axis
and c = distance between focus and center
If c = 6 cm, b = 8 cm,
6² = a² - 8²
a² = 6² + 8²
a² = 36 + 64
a² = 100
a = 10 cm
Therefore, length of the major axis is 10 cm.
Option (B) is the answer.
Depends is the positive integer is larger than the negative interger for example -10+5=-5.
10+-4=6
