Answer:

Step-by-step explanation:

The most important part of this question is the estimation. That means you round either up or down to get whole numbers.

You can make - 37.44 either - 40 or - 35

You can make 4.8 into 5

So the answer should lie between -40/5 = - 8

or

The answer should be between - 35/5 = - 7

Use your calculator to check it.

-37.44 ÷ 4.8 = - 7.8

This skill is very handy when shopping or writing a test. It you get an outrageous answer like - 21.44 you know you have done something wrong.

An engineer stands 200 feet from a tower and sights the top of the tower at a 45° angle of elevation. Find the height of the tow
Alik [6]
Drawing a diagram of a triangle may be helpful. The hypotenuse is irrelevant, but the vertical leg and the horizontal leg are useful. Since we know the engineer is looking up at a 45 degree angle from a distance of 200 feet, we can label the vertical leg the "opposite", since it is on the opposite side of the angle we are given. The horizontal leg then becomes the "adjacent". You can then use trigonometry to solve for the opposite. 
The options are:
sin(theta)= opposite/hypotenuse
cos(theta)= adjacent/hypotenuse
tan(theta)= opposite/adjacent
Since we don't care about the hypotenuse, the last equation is the one to use. The angle we are given can be substituted in for theta:
tan(45)= x/200
1.61977519= x/200
x= 323.955038 feet

According to​ psychologists, IQs are normally​ distributed, with a mean of 100 and a standard deviation of 15 . a. What percenta
Angelina_Jolie [31]
Answer: 34%.

By definition of normal distribution, ≈68% of the data is within 1 standard deviation of the mean. Therefore 68% of IQs are between 85 and 115, and half of that is on the lower end, 85 to 100.

Select the expression that simplifies to 1 / x^1/8
Troyanec [42]

Answer:

\left(\displaystyle \sqrt[3]{x^{-\tfrac 35}}\right)^{\tfrac 58}

Step-by-step explanation:

\left(\displaystyle \sqrt[3]{x^{-\tfrac 35}}\right)^{\tfrac 58}\\\\\\=\left[ \left(\displaystyle x^{-\tfrac 35} \right)^{\tfrac 13 \right]^{\tfrac 58}\\\\\\=\left( \displaystyle x^{-\tfrac 35}\right)^{\tfrac 5{24}}\\\\\\=x^{ \displaystyle -\tfrac{3}{24}  \right}\\\\\\=x^{\displaystyle -\tfrac 18  }\\\\\\=\dfrac 1{x^{\tfrac 18}}
