Draw a line segment 7cm long .
White raven [17]

Answer:

The line segment 7 cm long is shown below.

Step-by-step explanation:

First we draw a line line segment whose length is 7 cm long. Then we divide the line in small parts.

The length of each part is 1 cm.

Six points on the line segment divides the line in 7 equal parts and length of each part is 1 cm.

From the figure it is noticed that we have total 7 small parts and length of each part is 1 cm. So length of 7 parts is

7\times 1=7

Hence the total length of line is 7 cm.

Please help me in this question.Tell me if it is good. And if it is not good then do it for me please.
Orlov [11]

Answer:

Y = 170, Z = 64.

Step-by-step explanation:

Since y is the external angle to x, which you got right, it is in fact, 180-10, = 170 degrees. And since z is the external to our unknown angle, that means it is equal to the sum of the other two angles in the triangle. That means z is 54 + 10, which is 64.

The tires on Eric's car have a diameter of 18 inches. Rounded to the nearest whole number, how many rotations per second does ea
Step2247 [10]

Answer:

Step-by-step explanation:

We need to figure out how far Eric's car takes him in 1 rotation based on the diameter of his tire in feet. If the diameter of the tire is 18", then it is 1.5'. The circumference will tell us the distance 1 rotation of his tires will take him:

C = 3.1415(1.5) so

C = 4.71225 feet is how far he goes in 1 rotation. If he travels 88 feet in 1 second, we can figure the number of rotations by dividing 88 by 4.71225 to give us the unit rate (or, rotations per second his car makes). This quotient is 18.67 feet per sec, which rounds to 19, choice B.
