Answer:

A. 280°

Step-by-step explanation:

Look at angles 1 and 2. Together, they form a straight angle. The measure of a straight angle is 180°.

We are told that the measure of <2 is 40°.

Since angles 1 and 2 together measure 180°, then the measure of <1 must be 140° since 180° - 40° = 140°.

Now we have m<1 = 140°.

Angles 1 and 6 are vertical angles. Vertical angles are congruent.

Therefore, m<6 = 140°.

We have m<1 = 140° and m<6 = 140°.

m<1 + m<6 = 140° + 140° = 280°

Answer: A. 280°

Which fraction represents the decimal 0.8888...?

suter [353]

Answer: The decimal 0.88888.... represented by the fraction $\dfrac{8}{9}$

Step-by-step explanation:

Since we have given that

0.888888....

So, Let x = 0.88888....= $0.\bar{8}$ -----(1)

Now, multiply by 10 on both sides, we get that

$10x=8.8888.....=8.\bar{8}----------(2)$

Now, Subtracting (1) from (2), we get that

$10x-x=8.\bar{8}-0.\bar{8}\\\\9x=8\\\\x=\dfrac{8}{9}$

Hence, the decimal 0.88888.... represented by the fraction $\dfrac{8}{9}$

Using a 10' long piece of strut as a straightedge, you are trying to determine the outside diameter of a grain storage silo. You

Vesna [10]

The radius of the silo is the distance from its center to the outside wall

The radius of the silo is 7 3/8" or 7 3/8 inches

<h3>How to determine the radius?</h3>

From the question, we have the following parameters:

Length of strut = 10'
Outside diameter of silo = 14 3/4"

The radius is then calculated as:

Radius = 0.5 * Diameter

This gives

Radius = 0.5 * 14 3/4"

Evaluate the product

Radius = 7 3/8"

Hence, the radius of the silo is 7 3/8" or 7 3/8 inches
