Answer:

x=11

Step-by-step explanation:

supplementary angles add up to 180 degrees

10x + 70 =180

10x = 110

x=11

11x10 = 110

110+70 = 180

5x - 4 = -3x + 12. Solve for x

leva [86]

5x - 4 = -3x + 12.

move -3x to the other side

sign changes to +3x

5x+3x-4= -3x+3x+12

5x+3x-4= 12

move -4 to the other side

sign changes to +4

5x+3x-4+4= 12+4

8x= 16

divide by 8 for both sides

8x/8= 16/8

x= 2

A bridge connecting two cities separated by a lake has a length of 5927.261 yd. use the table of facts to find the length of the

alex41 [277]

Answer:

the length of the bridge in miles is 3.37 miles

Step-by-step explanation:

The computation of the length of the bridge in miles is shown below:

Given that

The length is 5927.261 yard

As we know that

1760 yard = 1 mile

So 1 yard = 1 ÷ 1760 mile

For 5927.261 yard, the miles would be

= 5927.261 ÷ 1760

= 3.37 miles

Hence, the length of the bridge in miles is 3.37 miles

Answer:

Second hand will turn through 74π radians.

Step-by-step explanation:

There are 37 minutes left in the class. We need to find by how much angle will the second hand turn before the end of the class.

When a second hand completes one full rotation along the clock it covers 360 degrees and completes 60 seconds.

This means:

In 60 seconds, the second hand turns by 360 degrees

Since, 60 seconds = 1 minute, we can write:

In 1 minute, the second hand turns = 360 degrees

360 degrees is equal to 2π radians. So,

In 1 minute, the second hand turns = 2π radians

Multiplying both sides by 37 gives us:

In 37 minutes, the second turns = 2π radians x 37 = 74π radians
