m_a_m_a [10]

The measure of the angle m∠CBD that forms an adjacent angle is 35 degrees.

<h3>What are adjacent angles?</h3>

Adjacent angles are angles that have common side and vertex.

Therefore, the common vertex is at point B.

m∠CBD = m∠ABD -  m∠ABC

Therefore,

m∠ABD = 75 degrees

m∠ABC = 40 degrees

Hence,

m∠CBD = 75 - 40

m∠CBD = 35 degrees

Solve the word problems. Round the answer to the nearest tenth.
damaskus [11]

Option A:

The shortest distance Mark can cover to reach home early is 54.7 miles.

Solution:

Towards North  = 35 miles

Towards West = 42 miles

Using Pythagoras theorem,

<em>In right triangle, squares of the hypotenuse is equal to the sum of the squares of the other two sides.</em>

Let x be the hypotenuse.

x^2=35^2+42^2

x^2=1225+1764

x^2=2989

Taking square root on both sides, we get

\sqrt{x^2}=\sqrt {2989}

x = 54.67

x = 54.7

The shortest distance Mark can cover to reach home early is 54.7 miles.

Option A is the correct answer.

A baseball pitcher has pitches 98 2/3 innings. What is the number of innings written as a decimal?
Bingel [31]

98⅔ is simply 98 + ⅔, now, how much is ⅔?

well, to convert any fraction to decimal, recall that a/b is just a ÷ b, so ⅔ is just 2 ÷ 3, or 0.6666.....

so 98 + ⅔is then 98 + 0.66666... or just 98.67 rounded up.

Step 1: Define

Slope <em>m</em> = 1/2

Point (-4, 7)

Step 2: Substitute
