Answer:

x=7.90 x≈8

Step-by-step explanation:

they are alternate interior angles

so: 7x+6+15x=180

22x+6=180

22x=174

=7.9090......

you can double check my work

Answer:

Angle WTS will be 180 degree minus 15x. You can write this as an expression:

180-15x

Now you have an expression for each angle in the triangle. Triangles will always have 180 degrees in them. You can add the expressions together and set it equal to 180. Then you can solve the equation for the x variable.

Step-by-step explanation:

Angle SWT + angle WTS + angle TSW = 180 degrees

Replace each angle with the expression then solve.

svp [43]

Answer:

40%

Step-by-step explanation:

Tanya has a a choice of 5 different routes (1-20 mins, 2-30 mins, 2-40 mins).

How many routes can she take that will take her 30-mins to get home?

The answer is 2.

What's the probability she will take 2 of the 5 routes to get home?

The probability is 2/5 so 40%.

The rounding instruction was there to mislead you in this case :-)

Answer:

50.24 yd^2

Step-by-step explanation:

The area of a circle can be found using:

a=\pi r^{2}

First, we need to find the radius. We have the diameter. The diameter is twice the radius, or

d=2r

We know that the diameter is 8, so we can substitute 8 in for d

8=2r

Since we are trying to find r, we need to get r by itself. To do this, divide both sides by 2.

8/2=2r/2

4=r

Now we know the radius, and can substitute 4 in for r. Also, we can substitute 3.14 in for pi.

a=\pi r^{2}

a=3.14*4^2

Solve the exponent

a=3.14*16

Multiply

a=50.24

The area is 50.24 yards^2

If Bill was traveling v mi/h, how would you represent Daemon's speed in mi/h if he was traveling 45 mi/h faster?
VikaD [51]

The sum of two variables having the same units is given by adding the magnitudes of the quantities and expressing the outcome in the units of the quantities

Daemon's speed is (v + 45) mi/h

The reason the above value for Daemon's speed is correct is as follows:

The known parameters are;

The speed with which Bill was travelling = v mi/h

The speed with which Daemon was travelling = 45 mi/h faster than Bill

Method:

By dimensional analysis, we note that the given quantities have the same units, and therefore, they represent the same quantity of speed

To find Daemon's speed, the amount by which his speed is more than that of Bill's speed is added to the given amount of Bill's speed as follows;

Solution:

Daemon's speed = v mi/h + 45 mi/h = (v + 45) mi/h
