In 2012, The U.S. Population Was About314 Million. How Many People Over Theage Of 64 Were In The U.S.?

Answers

Answer 1

There are 38,936,000 people over the age of 64 were in the U.S.

Option 2 is true.

What is Percentage?

A relative value indicating hundredth part of any quantity is called percentage.

Given that;

In 2012, the U.S. population was about 314 million.

Now,

Total population = 314,000,000

In the pie chart, The percent of people over the age of 64 were in the U.S will be 12.4%

Hence, Solve as;

Number of people over the age of 64 = 314,000,000 × 12.4%

                                                           = 314,000,000 × 12.4 / 100

                                                           = 31,400,00 × 12.4

                                                           = 38,936,000

Thus,

Supervisor : “ you have been doing really well . You received ratings of 85, 90, 100 and 90 . What’s your monthly average ?

Answers

The average monthly rating is 91.25.

How to estimate averages?By adding a set of integers and then dividing by their count, the average, or arithmetic mean, is determined.Finding an average helps us determine a general pattern of behavior or trend.To compare different quantities of the same category, averages are utilized.In other words, the average is the proportion between the total number of observations and the sum of all observations presented.The common formula of average is:

         Average = Sum of the Observations/Number of Observations

Given:

The received ratings are 85, 90, 100, and 90.

Average monthly rating = Sum of ratings/ total number of ratings

                                       = (85 + 90 + 100 + 90)/ 4

                                       = 365/ 4

A restaurant is having a deal for Valentine's day and is offering a 4-course meal for $27.00. If there is a sales tax of 8 percent, what is the actual cost of the meal?

Answers

Answer:

  $29.16

Step-by-step explanation:

You want the total cost of a $27 meal after 8% tax is added.

Tax

The amount of added tax is found by multiplying the meal cost by the tax rate:

  0.08 × $27.00 = $2.16

Total

The total cost is the meal cost plus the tax:

  $27 +2.16 = $29.16 . . . . actual cost of the meal

Additional comment

The sum 27 + 0.08×27 can also be found by factoring out the 27:

The given table shows that does not show a proportional relationship, as the ratio between the output and the input is not the same for all terms of the table.

What is a direct proportional relationship?

A direct proportional relationship is a function in which the output variable is given by the multiplication of the input variable and the constant of proportionality k, as defined below.

y = kx

In this problem, we have that:

The input x is the number of pounds of apples.The output y is the cost of the apples.

To verify if it shows a proportional relationship, we have to divide the output by the input in each case, hence:

k = 3.76/2 = 1.88.k = 5.64/3 = 1.88.k = 7.53/4 = 1.8825.k = 9.40/5 = 1.88.

Answers

By using the elimination method,  the numbers are 11 and 30

Consider the first number as x and the second number as y

Sum of 5 times the first number and 6 times the second number is 235

The linear equation will be

5x+6y = 235

The difference between 7 times the first number and 17 is 2  times the second number

7x-17 = 2y

Rearrange the terms

7x-2y = 17

The both equations are

5x+6y = 235

7x-2y = 17

Multiply the first equation by 2 and second equation by 6

10x+12y = 470

42x-12y = 102

Here we have to use the elimination method

Add both equation and y term will cancelled

10x+42x = 470+102

52x = 572

x = 11

Substitute the value of x in any equation

5x+6y =235

5(11)+6y = 235

55+6y = 235

6y = 180

y = 30

The recipe for junk crunchies requires a total of 8 cups of sugar and flour together. If the recipe had called for 1/4 cup more sugar, the amount of sugar would be half the amount of flour. How many cups of sugar does the recipe call for?

Answers

The recipe of the junk calls for 16/7 cups of sugar

How to determine the number of cups of sugar in the recipe?

From the question, the given parameters are:

Total number of cups = 8

Let the number of cups of sugar be x and the number of cups of flour be y

So, we have the following equation

x + y = 8

Also, we have:

The recipe uses 1/4 cup more sugar, so the amount of sugar equals half the amount of flour

This means that

(1 + 1/4) * x = 1/2 * y

Evaluate the sum and the products

So, we have

5/4x = 1/2y

Make y the subject

y = 5/2x

Substitute y = 5/2x in x + y = 8

x + 5/2x = 8

Evaluate the sum

3.5x = 8

Divide by 3.5

x = 16/7

Hence, the cups of sugar is 16/7

How can you tell?

Step 1

Describe the function,

.

Let

x, the number of bags

shipping = 3 dollars

Charges=$12 for each bag, then

charges=12*x

Now, the total is

total=charges + shipping

total=12x +3

now, we have a function ( the total (y) depends on the number of bags)

[tex]y=12x+3[/tex]

where

y is the total charge, and x is the numbers of bags

Step 2

assume values for x, replace and find y

x=-3

then y=12(-3)+3, y=-36+3, y=-33

so, when x=-3, y=-33

2

then y=12(-2)+3, y=-24+3, y=-21

so, when

x=-2, y=-21

then y=12(-1)+3, y=-12+3, y=-9

so, when

Law of sines defines the ratio of sides of a triangle and their respective sine angles are equivalent to each other.

In other words,  the law of sines is defined as the ratio of side length to the sine of the opposite angle.

It holds for all the three sides of a triangle respective of their sides and angles.

Therefore, the law of sine can be expressed as follows:

The longest and shortest possible lengths of the third side of the triangle are 4.9 cm and 11.1 cm.

What does the Angle Bisector Theorem state?

It states that the opposite side of a triangle is divided into segments by each angle bisector that are proportional in length to the adjacent sides.

Given:

An angle bisector divides the opposite side of the triangle into segments 6 cm and 4 cm long.

Second side of the triangle is 7.4 cm.

We have to calculate the longest and shortest possible lengths of the third side of the triangle.

By Angle Bisector Theorem we can solve this problem,

In the triangle ABC, AD is the angle that bisects angle A, placing D on side BC.

Now, BD / DC = AB / AC

BC = 6 + 4 = 10 cm

Angle bisector divides BC into 2 segments,

BD = 6 cm

CD = 4 cm

If AB = 7.4 cm,

6/4 = 7.4 / AC

AC = 7.4(4) / 6

AC = 29.6 / 6

AC = 4.94 cm (shortest possible length of the third side of the triangle)

If AC = 7.4 cm

6/4 = AB/7.4

AB = 6(7.4)/4

AB = 44.4/4

AB = 11.1 cm (longest possible length of the third side of the triangle)

Suppose we have a triangle in which:

The length of the side opposite to angle A is given by a.The length of the side opposite to angle B is given by b.The length of the side opposite to angle C is given by c.

The lengths and the sine of the angles are proportionally related as follows:

[tex]\frac{\sin{A}}{a} = \frac{\sin{B}}{b} = \frac{\sin{C}}{c}[/tex]

From this relation, we have that:

The greatest angle is opposite the largest side.The smallest angle is opposite the smallest side.

In this problem, we have that:

Broadway is the hypotenuse, hence the greatest angle is formed by the intersection of Main Street and Water Street.Due to the smaller distance, of 1200 m, compared to 1600 m and 2000 m, the smallest angle is formed by the intersection of Broadway and Main Street.
