50+10(8*1)+2
What property do you use to solve this and how.

Answers

Answer 1

Answer: You need to use PEMDAS
So first you do the parenthesis.
8*1=8.
So now re-write the problem.
50+10*8+2
Now you are going to multiply.
10*=80
Now re-write the problem again.
10+80+2
10+80=90+2=92
So the answer to this problem is 92.

Answer 2

Answer: You should use PEMDAS
(parenthesis, exponents, multiply, divide, add, and subtract)

Step-by-step explanation:

The angle 305° is in the fourth quadrant

To find the related acute angle ( the reference angle ) subtract from 360°

reference angle = 360° - 305° = 55°

The population of a city in 2005 was 18,000. By 2010, the city’s population had grown to 32,800. If the population growth follows a linear model, what is the projected population for 2015?

Answers

The projected population in 2015,assuming that the populationgrowth follows a linearmodelis 47600

Population in 2005 = 18000
Populationafter5years(2010)=32800

Population change in 5 years :

2010 population - 2005 population

32800 - 18000 = 14800

Estimatedpopulationvaluein2015:

2010 Population + population change in 5 years

32800 + 14800 = 47600

Therefore, the projected populationsize in 2015is 47600

The rate is (32,800 - 18,000) = 14,800 per 5 years
therefore :
in 2015 = 2010 + 5 years
the pop. will be :
32,800 + 14,800 = 47,600

What number is one fourth of 360?

Answers

$(1)/(4)\cdot360=(360)/(4)=360:4=90$

90 is one-fourth of 360.

We have,

To find one-fourth of 360, we divide 360 by 4.

Dividing 360 by 4 gives us the result of 90.

Therefore, one-fourth of 360 is 90.

To explain further, one-fourth of a number is the same as dividing the number by 4.

In this case, when we divide 360 by 4, we obtain the result of 90.

Thus,

90 is one-fourth of 360.

Clare estimates that her brother is 4 feet tall. When they get measured at the doctor’s office, her brother’s actual height is 4 feet, 2 inches. Should Clare's or the doctor's measurement be considered the actual height? Explain your reasoning. What was the error, expressed in inches? What was the error, expressed as a percentage of the actual height?

Answers

Answer:

Percentage of error by Clare is estimated as 4.1667 %.

Step-by-step explanation:

Height measured by Clare = 4 feet

Height measured by Doctor = 4 feet, 2 inches

Percentage error = ?

Percentage error = Difference/ Actual height *100

Percentage error = (2/ (4*12))*100

Percentage error = 4.1667 %

The accurate height is measured by Doctor, as he have more accurate measurement system.

Final answer:

The doctor's measurement is the actual height. The error in Clare's estimation is 2 inches or 4% of the total height.

Explanation:

The doctor's measurement should be considered the actual height because it is the factual measurement obtained, while Clare's was an estimate based on her observation.

The error in Clare's estimate, compared to the actual height, is 2 inches. To calculate the error as a percentage, we first convert the actual height to inches (50 inches = 4 feet 2 inches), then divide the error by the actual height and multiply by 100 to get the percentage.

So, the error as a percentage is (2/50)×100 = 4%.

Let me try . . .

When two lines intersect, they form four (4) angles, all at the same point.
There are two pairs of angles that DON't share a side, and a bunch of other
ones that do share sides. A pair of angles that DON't share a side are called
a pair of "vertical angles".

A pair of vertical angles are equal, but this problem isn't even asking you about
that; it's just asking you to find a pair of vertical angles.

Since you and I are not sitting together at the same table, I can't point to
the drawing and point out different angles to you. You just have to go
through the choices, and find a choice where both angles are formed from
the same two lines.

The first choice (KRE and ERT) is no good, because KR, RE, and RT
are parts of three different lines.

Check out the other 3 choices, and you're sure to find the only one where
both angles are formed by the same two lines.

this would be C because the liners are not intersecting
