Find the value of b here

Mathematics
1 answer:
sweet [91]3 years ago
8 0

Answer:

Step-by-step explanation:

We will start with the angle that measures 57 degrees. This angle is supplementary to the one next to it coming off the straight line. 180 - 57 = 123.

The rule for quadrilaterals is that same side angles are supplementary, so the angle next to the 123-degree angle (to the immediate left of that angle 123) is 57. THAT 57-degree angle is supplementary to angle b, so angle b = 180 - 57 which is 123. So C is your answer.

2 ft
sdas [7]

Answer:

88/7 ft = 12.6 ft (nearest tenth)

Step-by-step explanation:

Circumference of a circle = 2\pir

<u>Radius of inner circle</u>

Given:

  • circumference of inner circle = 22ft
  • \pi = 22/7

⇒ 22 = 2 x (22/7) x r

⇒ r = 3.5

So the radius of the inner circle is 3.5 ft

<u>Radius of outer circle</u>

If the distance between the inner circle and the outer circle is 2 ft, then the radius of the outer circle = 3.5 + 2 = 5.5

<u>Circumference of outer circle</u>

Therefore, circumference of outer circle:

=  2 x (22/7) x 5.5

= 242/7 ft

<u>Difference between circumferences</u>

Difference = outer circle circumference - inner circle circumference

                  = 242/7 - 22

                  = 88/7 ft

                  = 12.6 ft (nearest tenth)

If someone ran 14.6 miles from their house and then they are now 9.8 miles from their house and finally they are 5.3 miles away
elixir [45]

Answer:

<u>10.1 miles</u> far is their house.

Step-by-step explanation:

Given:

If someone ran 14.6 miles from their house and then they are now 9.8 miles from their house and finally they are 5.3 miles away.

Now, to find the distance is far from their house.

14.6 miles distance they ran from their house.

So, they are far from house = 14.6\ miles.

Then, 9.8 miles they are from their house.

So, they are far from house = 14.6-9.8\ miles=4.8\ miles.

And, finally 5.3 miles away from their house.

So, now they are far from house = 4.8+5.3=10.1\ miles.

Therefore, 10.1 miles far is their house.

Estimate the solution to the system of equations.
Katen [24]

Answer:

The solution is: x = -1, and y = 8/3

Step-by-step explanation:

Notice that the system of equations can be easily solved via the "elimination" method, by subtracting term by term one equation from the other. Doing such will remove completely the term in "y" (since the terms in "y" are exactly equal in both equations), and leave only an equation containing "x", for which the value can be solved:

2x+3y=6\\-4x+3y=12\\\\ \\2x-(-4x)+3y-(3y)=6-12\\6x+0=-6\\x=-1

Now we use this x-value in either equation to solve for y:
