Rus_ich [418]

Answer:

The measure of angle a is 35 degrees, b is 55 degrees and c is 110 degrees.

∡a has an angle of 40°. Vertical angles are always congruent.

∡b is the 3rd angle in a triangle, the other two are 40° and 90° all of the interior angles in a triangle add up to 180°.

∡c is a linear angle, linear angles always add up to 180°.

Harry Parsons' annual salary is $112,600. He pays $4,424 in state taxes annually based on a state tax rate of 4%. What is Harry'
aliina [53]

Harry Parson's marital status is as a single taxpayer with no dependents.

Parson's taxable income for state taxes is $110,600 ($112,600 - $2,000).

Data and Calculations:

Annual salary = $112,600

Annual state taxes = $4,424

State tax rate = 4%

Taxable income = $110,600 ($4,424/4%)

Personal allowance = $2,000 ($112,600 - $110,600)

Thus, Harry Parson files as a single (unmarried) taxpayer with no dependent but claims a personal allowance of $2,000.

a car traveling at a constant speed travels 175 miles in 4 hours? How many minutes will it take for the car to travel 1000 feet?
liubo4ka [24]

Answer:

0.26 minutes

Step-by-step explanation:

So if you want to solve this, you need to make all the units the same first. What you first need to work on is the rate, since what it is asking is minutes given distance in feet.

We know that there are:

5280 ft in a mile

60 minutes in an hour

We then convert the rate knowing this:

\dfrac{174\:miles}{4\:hours}\times\dfrac{5280ft}{1\:mile}\times\dfrac{1hour}{60\:minutes} = \dfrac{918,720ft}{240\:minutes} = \dfrac{3828\:feet}{1 minute}

In short, the car is traveling 3,828 ft every minute.

To determine how many minutes it will take for the car to travel just remember that:

speed=\dfrac{distance\:travelled}{time}\;\rightarrow\;time=\dfrac{distance\;travelled}{speed}

Now we plug in what we know and solve what we don't know:

time=\dfrac{1000feet}{\dfrac{3828ft}{1minute}}\;\rightarrow\;1000ft\times\dfrac{1\:minute}{3828ft}=0.26\:minutes

I am simplifying radicals and I've come across one that has me a bit confused.
zhenek [66]

The sqrt of (34 m^4) is  sqrt(34) times sqrt(m^4).

The sqrt of m^4 is easy ... that's just  m^2 .

The other part is more messy.  There's not much you can do with it.

                      sqrt(34) = sqrt(17) times sqrt(2). 

That doesn't help make it any simpler.
You might as well just leave it as sqrt(34). 

Then the final, simplified form of the original expression is

                          m^2 sqrt(34)
