Answer:
40
Step-by-step explanation:
The frequency column gives the number of houses in the sample, then
number of houses = 5 + 11 + 23 + 1 = 40
Convert 3h and 45 min to hours so it will be 3.9 hours
Then say:
Distance = speed ✖️time
= 122 km/h ✖️3.9h
=475.80 km
He will travel 475.80 km
Hope this helps ;)
Answer:
The height of the lighthouse is approximately 166.6 feet.
Step-by-step explanation:
Let the height of the lighthouse be represented by s, then;
Tan 48° = (opposite) ÷ (adjacent)
Tan 48° = s ÷ 150
⇒ s = 150 × Tan 48°
= 150 × 1.1106
= 166.59
s ≅ 166.6 feet
Therefore, the height of the lighthouse is approximately 166.6 feet.
Answer:
15, -9
Step-by-step explanation:
It is given that J and K are points on the number line. J lies at 3 and JK=12.
We kneed to find the location of K.
A number line is a straight line with numbers placed at equal intervals and extended infinitely in any direction.
If K lies on the left side of J then the location of K is
3 + 12 = 15
If K lies on the right side of J then the location of K is
3 - 12 = -9
The locations of K are defined by the below number.
Therefore the locations of K are 15 and -9.
