Heather would have to work 4.6 hours to make $65.

Time and work is a branch of mathematics that deals with the relationship between the time required to complete a task and the amount of work done. The basic formula used in time and work is:

Work = Time x Rate

Where,

Work = amount of work done

Time = time taken to complete the work

Rate = the rate at which the work is done

We can calculate this by using the formula:

Hours = (Money earned / Hourly rate)

In this case, you can use the proportion:

(x hours) / (65) = (12 hours) / (156)

Solving for x you get:

x = (65 * 12) / 156 = 4.6 (approximately, rounded to the nearest tenth)

Therefore, Heather would have to work 4.6 hours to make $65.

In this case, you can use the proportion:

The equation which represents the same line as the points in the table is y = -3/4 x + 2. (Option C)

The equation of the points given in the table can be determined by using the slope-intercept form which is given by:

y = mx + b

where m is the slope of the line and b is the y-intercept.

The slope of the line can be determined by:

m = rise/run = Δy/ Δx = (y2 – y1)/(x2 – x1)

Hence, taking two points from the table say (-4, 5) and (0, 2)

m = (2 – 5)/(0 – (-4)) = -3/4

y intercept is the value of y when x = 0

From the table, y-intercept b = 2

Hence, the equation of the line is: y = -3/4 x + 2

When each number is rounded to the nearest hundred, the difference I 100 the number could be 14,499 less 13,500 or 999

To the closest hundred, the biggest number that can be named 14,000 is 14,050. To the closest hundred, the least number that can be named 14,000 is 13,950. There is a 100 difference between the two.

This claim may be generalized as follows.

The difference between the upper and lower limits is m for any integer N that has been rounded to the nearest m.

The maximum is N+m/2.

N-m/2 is the lower limit.

(N+m/2) is the difference between the two. (N-m/2) = (N-N) +m/2 - (N-N) -m/2

There were 192 birds in the aviary in total.

There were 16 habitats in the aviary at the zoo, and each habitat had 12 birds. To find out how many birds were in the aviary in total, we need to multiply the number of habitats by the number of birds in each habitat.

16 habitats * 12 birds/habitat = 192 birds

So there were 192 birds in the aviary in total.

This is done by using the distributive property of multiplication. Basically, if you have a certain number of groups, each containing a certain number of items, and you want to find the total number of items, you can multiply the number of groups by the number of items in each group. In this case, the number of groups is the number of habitats (16) and the number of items in each group is the number of birds (12). So by multiplying those two numbers together, we get the total number of birds in the aviary.

Therefore, There were 192 birds in the aviary in total.

16 areas with 12 birds each equals 192 birds.

Thus, there were 192 animals in all in the aviary.

Utilizing multiplication's distributive principle, this is accomplished. Basically, you can increase the total number of groups by the total number of items in each group if you have a certain number of groups, each of which contains a specific number of items. In this instance, the number of objects in each group equals the number of birds, and the number of groups equals the number of habitats (16). (12). We can calculate the overall number of birds in the aviary by multiplying those two numbers.

Consequently, there were 192 animals in all in the aviary.

8 gigabytes would have to be used for the plans to cost the same. The cost will be $100.

Given is that Smart One smartphone plan cost $20 per month for talk and messaging and $10 per gigabyte of data used each month. A second smartphone plan cost $60 per month for talk and messaging and $5 per gigabyte of data used each month.

Let {C} represent the total cost in dollars and {D} represent the amount of data used in gigabytes. The system of equation can be used to represent this situation are -

C = 20 + 10d

C = 60 + 5d

For same cost -

20 + 10d = 60 + 5d

5d = 40

d = 8

The cost would be -

C = 20 + 10d

C = 20 + 10 x 8

C = 100

Therefore, 8 gigabytes would have to be used for the plans to cost the same. The cost will be $100.

The hypotenuse is the longest side of a triangle which is opposite to the right angle.

A right triangle's hypotenuse is always the side that faces the right angle. This side is longest in a right triangle. The other two sides are those that are opposed and close by. The labels on these sides relate to an angle.

The word "hypotenuse," which refers to the longest side, is derived from two Greek roots that mean "to stretch." One side is across from another at a particular angle. The non-hypotenuse side that lies next to a particular angle is known as the neighboring side.

The area of the triangle xyz is 33.941...

To calculate area of triangle, we need to take the base and height's measurement.

Formula- 1/2 x Base x Height

However, Area may also be calculated when we know the 3 sides of the triangle.

It is known as "Heron's Formula"

Simply use this 2 step process :

Step 1-

Calculate "S" (which is half of the triangle's perimeter)

S = (side1 + side2 + side3) / 2

Naming the sides as a b and c respectively.

4 inches = a

5 inches = b

7 inches = c

 S = ( a + b + c ) / 2

S = ( 4 + 5 + 7 ) / 2

S = 16/2

S = 8

Step 2: Calculating the area of the triangle XYZ

Formula:

Area ( A ) = √S(S−a)(S−b)(S−c)

put the values and you will get the answer.

A = √8(8−4)(8−5)(8−7)

Given that You walk into a store and see a sign that says "Tv: 47% off, only pay $1,500 today!"

We have to find the original price of the TV.

Convert 47% to decimal value.

47/100=0.47

Now multiply 0.47 with x which gives 1500

0.47x=1500

Divide both sides by 0.47

x=1500/0.47

x=$3191.48

Now add $1500 and $3191.5 to find the original price.

And here we need to find the vertex for the function that can be calculated as,

As we all know that vertex form of a parabola is written as,

=> y = a (x - h)² + k

Here we know that (h, k) is the vertex

Then the given expression is written as,

=> g(x) = -3x²  + 18x + 2

When we can be written by completing the square as follows,

=> y = -3x²  + 18x + 2

Here we have to take 3 as common term, then we get

=> -3(x²  + 6x)+ 2

now, we have to expand the expression within the brackets, then we get,
