Answer:
4 /15
Step-by-step explanation:
From the number cube :
Count of Numbers greater than 4 = 16
Sample space of number cube = 20
P(number greater than 4) = 16 / 20 = 4/5
Word : ATTENTION
Count of letters in attention = 9
Count of T's in attention = 3
P(choosing T) = 3 / 9 = 1/3
P(greater than 4, then T) = 4/5 * 1/3 = 4 /15
Answer:
8
Step-by-step explanation:
You use law of sines, and get: AB/sin(53) = 7/sin(44)
You multiply both sides by sin(53), and get:
AB = 7*sin(53)/sin(44)
That means AB is 8.04776679886, which rounds to 8
Honestly i just wanted to try this question since ive never seen it but i dont rlly know if i did it right at all
I equaled GH, HI, and GI together to get y
which i got y=-2
and what i got next i feel is off since
GH, HI, and GI all equaled -11
if you kind of know how to do the question maube you could correct me from there but otherwise dont take my word for it completely
The new perimeter would be 60. because the width and the height are doubled.
Jenny average swimming speed was 2.5 km/h, her average biking speed was 24 km/h and her average running speed was 12 km/h.
<h3>Speed</h3>
Speed is the ratio of total distance travelled to total time taken. It is given by:
Speed = distance / time
Let a represent the average swimming speed, b the average biking speed and c the average running speed.
Her average biking speed was 2 times her average running speed, hence:
Her average running speed was 8 times her average swimming speed. Hence:
Total distance of the triathlon was 55.5 kilometers. Hence:
a * 1 hour + b * 1.75 hour + c * 1 hour = 55.5 (3)
From equation 1, 2 and 3:
a = 2.5, b = 24, c = 12
Jenny average swimming speed was 2.5 km/h, her average biking speed was 24 km/h and her average running speed was 12 km/h.
