Answer:
The speed is:
5 meters per second
In then seconds: 50 meters
Step-by-step explanation:
1 hour = 3600 seconds
1 km = 1000 meters
18km = 18*1000 = 18000 meters
then:
18km/h = 18000m/3600sec = 5m/s
The speed is:
5 meters per second
proportions:
5 meters ⇔ 1 second
W meters ⇔ 10 seconds
W = 5*10/1
W = 50 meters
Answer:
x = 15°
Step-by-step explanation:
<em><u>The segment is a diameter, So let us assume the part in which there lies the triangle as a semicircle.</u></em>
=> <em>A triangle inscribed in a semi-circle will always have one of its angle equal to 90</em>
=> <em>So the angle (not 75 and x) is 90 degrees.</em>
<em>=> To find the value of x, we'll subtract rest of the angles from 180 degrees (because the interior angles of a triangle add up to 180°)</em>
<em>So,</em>
=> x = 180-90-75
=> x = 15°
Answer:
1,512 cm³
Step-by-step explanation:
The general formula for the volume of a prism is:
V= Bh, where B = the area of the base and h = height of the prism
Given the dimensions of the smaller block as 9cm x 3cm x 7cm, then the dimensions of the larger block (double the dimensions of the smaller block) must be 18cm x 6cm x 14cm. Using these measurements:
V = (18)(6)(14) = 1,512 cm³
Input the first coordinate of an ordered pair in a relation and output the second coordinate of an ordered pair.
