Answer 1

Answer: Hello,

$x_(1) , x_(2) , x_(3) , ... x_(50) \n\n \overline{x}= (\sum_(i=1)^(50)\ x_(i))/(50) \n\n (\sum_(i=1)^(50)\ 53-x_(i) )/(50) =-3.5\n (50*53 )/(50) -(\sum_(i=1)^(50)\ x_(i))/(50)=-3.5\n\n 53-\overline{x}=-3.5\n \overline{x}=53+3.5=56.5\n$

Complete Question

The front of a podium is in the shape of a trapezoid with base lengths 4 and 8.5 feet. the height is 2 feet. a gallon of paint covers about 350 square feet. Bryan wants to paint the front of the podium blue. He decomposed the shape into two triangles and a rectangle to find the area.

How many front frames of a podium can Bryant paint with 2 gallons of paint?

Answer:

56 front podiums

Step-by-step explanation:

A proper look at the image attached will provide the explanations

Answer:

Step-by-step explanation:

Given:

Base length:

A = 8.5 m

B = 4 m

Height, h = 2 ft

1 gallon = 350 ft^2

Area of trapezoid = 1/2 × (A + B) × h

= 1/2 × (8.5 + 4) × 2

= 12.5 ft^2

1 gallon = 350 ft^2

2 gallons = 700 ft^2

1 podium = 12.5 ft^2

= 700/12.5 podium

= 56 podiums will be painted with 2 gallons of paint.

What's the Question? or the Problem you need Help

The Murphys’ gross annual family income is $120,500. Mr. Murphy referred to the graph shown below and calculated that his family will spend $28,920 on taxes this year. What is wrong with Mr. Murphy’s calculation?a.
He has calculated only federal taxes.
b.
He has calculated only state taxes.
c.
He does not need to include federal taxes.
d.
He does not need to include state taxes.

Answers

Mr. Murphy's calculation of the taxes they are to pay this year is wrong because a. He has calculated only federal taxes.

There are several taxes that an employed person must pay including:

Federal income taxes
Federal social security taxes
State taxes

Mr. Murphy only calculated the federal taxes and did not include the state ones which are usually higher than the federal tax. Once he includes the state tax, his calculation will be correct.

In conclusion, state taxes need to be paid for as well.

What is the value of x in the equation x-2/3 + 1/6 =5/6 ?

Answers

x is a negative one (-1). The negative one makes it so that the -2/3 is a positive when they multiply.

So in this problem we can see that 2 out of 3 of the fractions have a denominator of 6. One of the fractions (2/3) has a denominator of 3. But we can make the denominator 6 by multiplying it by 2!

Now the equation is:

x - 4/6 + 1/6 = 5/6

So now let's solve for x!

x - 4/6 + 1/6 = 5/6

x + 1/6 = 9/6 (Addition property of equality)

x = 8/6 (Subtraction property of equality)

Now we divide...

8 divided by 6 equals 1.33

Now if we plug that into the equation as 1 and 1/3...

1 and 1/3 - 2/3 + 1/6

2/3 + 1/6

4/6 + 1/6 = 5/6

So that means your answer is decimal 1.33 or mixed fraction 1 and 1/3

An angle is formed by the junction of two rays.
a. True
b. False

Answers

The most probable and most likely answer to this problem of true or false would be true.

An angle is formed by the junction of two rays. Usually, when two rays are in junction, two angles are formed. Either the formed angle is an acute angle, obtuse angle, or a right angle. The other angle that comes with the formed angle mentioned earlier would be a reflex angle. When two rays form just a line, the angle formed would be just one which is a complete rotation, thus the angle would be a 360 angle.
