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

The original price of the TV is $4691.5

percentage, a relative value indicating hundredth parts of any quantity.

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.

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)

Step-by-step explanation:

No, thirty-two is not a prime number i.e., it is a composite number.

A prime number is a number that has only two divisors that is 1 and the number itself. Consider the number 7, which has only two factors, 1 and 7 so it is a prime number. As another example, let's take the example of 8, which has two or more divisors of 1, 2, 4, and 8. This means that 8 is not prime i.e., it is a composite number. I have a number 32 and I need to check if it is prime. To do this, we need to determine 32 factors. The factors of 32 are 1,2,4,8,32, so 32

= 1×2×2×2×2. Here we see that 2, 4, and 8 are factors of 32 that are different from 1 and 32. So there are more than two factors. Therefore it is not prime.

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

Answer:

(a) 7.68 dollars

(b) 1927.07 pesos

Step-by-step explanation:

Setting up a conversion factor will be helpful in helping us solve this problem. A conversion factor shows the relationship between two different units, and and is used to convert from one unit to the other.

Our conversion factor is 1 U.S. Dollar = 19.61 Mexican pesos. To convert units, we can turn the conversion factor into a ratio (U.S. dollar ÷ 19.61 Mexican pesos or vice versa) and then multiply the given amount by the ratio. The unit that we want to end up with should always be in the numerator, and the unit we want to convert from should always cancel out in the denominator. This will be demonstrated when we solve the problems below:

(a) We want to convert from pesos to dollars, so we will multiply by the conversion factor (1 dollar / 19.61 pesos).

(b) Now we want to convert from dollars to pesos, so we will multiply by the conversion factor (19.61 pesos / 1 dollar).

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.
