The formula C = 0.35y efficiently calculates the total cost of y apples at $0.35 each. It demonstrates a straightforward linear relationship between cost and quantity.

To find the total cost (C) of y apples priced at $0.35 each, you can use the equation C = 0.35y. This formula multiplies the cost per apple ($0.35) by the number of apples (y) to give you the total cost. For instance, if you want to buy 10 apples (y = 10), the calculation would be C = 0.35 * 10, which equals $3.50.

This equation works because it represents a simple linear relationship between the cost and the quantity of apples. Each apple adds $0.35 to the total cost. Therefore, by multiplying the cost per apple by the number of apples, you get the overall cost.

Remember, this formula assumes a constant price per apple. If the price were to change, the equation would need to be adjusted accordingly. This calculation is useful for budgeting and understanding the cost implications of buying a specific quantity of apples at a given price.

The linear equation for the total cost of buying and using the new iPhone with Verizon is total cost = $899 + ($65 * 24), which simplifies to $2459 for 24 months.

To find the linear equation for the cost of buying and using the new iPhone with Verizon, we need to consider the initial cost of the iPhone and the monthly plan cost. Let's assume the initial cost of the iPhone X is $899 and the monthly plan is $65. We can represent the total cost after 24 months as a linear equation.

The equation can be written as:

total cost = initial cost + (monthly plan cost * number of months)

Since we want to find the total cost after 24 months, we substitute the values into the equation:

total cost = $899 + ($65 * 24)

Simplifying the equation:

total cost = $899 + $1560 = $2459

Therefore, the total cost after 24 months would be $2459.

Answer:

x = 5

Step-by-step explanation:

First, we need to move all the x's onto one side:

-7x-3x+8x = -8-2

Then, we simplify:

-2x = -10

To find x, we need to divide each side by -2:

So then x = 5

Answer:

its 0.60

Step-by-step explanation:

I did the quiz

The probability a random voltage is less than 124.2 volts is 0.60. Thus, option (C) is correct.

To find the probability that a random voltage is less than 124.2 volts, we need to know the distribution of the voltages. Let's assume that the distribution follows a normal distribution.

The Z-score formula is

Z = (X - μ) / σ,

where X is the value we are interested in, μ is the mean of the distribution, and σ is the standard deviation.

We want to find the probability that a random voltage is less than 124.2 volts.

Since the voltage is uniformly distributed, we can find this probability by calculating the proportion of the range that is less than 124.2 volts.

The range of the voltage is 125 - 123 = 2 volts.

The proportion of the range that is less than 124.2 volts is

= 124.2 - 123

= 1.2 volts / 2 volts

= 0.60.

Therefore, the probability a random voltage is less than 124.2 volts is 0.60.

Given problem is:

step by step solution:

we will add similar elements.

[tex]10^{10}(7.14+3.21)[/tex]

= [tex]10^{10} (10.35)[/tex]

Now converting [tex]10^{10}[/tex] in decimal form we get 10000000000 (10 zeroes)

Now multiplying 10.35 with 10000000000 we get 103500000000 (8 zeroes)

or we can change it to exponential form like [tex]1.035\times10^{11}[/tex]

11 because when you count from the extreme right end '0' and come counting to the left side, you skip 11 numbers till you reach the first number '1'. And when you put a decimal after 1st number, so the last '0' is at the 11th place, that is why it is [tex]10^{11}[/tex] .

The answer is C .2417 because you add them then divide by 7

To add 3 hours 20 minutes and 1 hour 48 minutes, you add the hours and minutes separately. Then convert the total to days.

To add 3 hours 20 minutes and 1 hour 48 minutes, you can simply add the hours together and the minutes together separately. Start by adding the hours: 3 + 1 = 4 hours. Then add the minutes: 20 + 48 = 68 minutes. Since there are 60 minutes in an hour, you can convert the excess minutes to hours by dividing by 60: 68 ÷ 60 = 1 hour. This gives a total of 5 hours. Therefore, 3 hours 20 minutes + 1 hour 48 minutes = 5 hours 8 minutes.

To convert this to days, divide the total number of minutes (308) by 60 to get the number of hours (5) and then divide by 24 to get the number of days: 5 ÷ 24 ≈ 0.2083 days.

1. You have that the number [tex]g[/tex] is divided by the number [tex]h[/tex]. Then:

[tex]\frac{g}{h}[/tex]

2. The words "is the same" indicates that you must write an equals sign after the division. Then, it says that it is seven more than twice the sum of [tex]g[/tex] and [tex]h[/tex]. This means that the sum of these two numbers are multiplied by 2  and then you must add 7:

The answer is the number 12. This is because if 12 is added to 24 it equals 36 and if 12 is multipled by 3 it is 36.

If a certain number is added to 24, the result is the same as if the number were multiplied by 3 the certain number is 12.

Let's assume the certain number is represented by "x."

According to the given information, if the number is added to 24, the result is the same as if the number were multiplied by 3. This can be written as the following equation:

x + 24 = 3x

Now, let's solve for "x":

Subtract "x" from both sides to isolate the "x" term on one side:

x + 24 - x = 3x - x

24 = 2x

Now, divide both sides by 2 to solve for "x":

x = 24 / 2

x = 12

Therefore, the certain number is 12.

Answer:

Refer below

Step-by-step explanation:

5) 9x+2 = 119 (alternate angles of a parallel line)

Hence 9x = 117: x=29 degrees.

6) 12x-8 and 108 are supplementary

Hence 12x+100 = 180 Or 12x= 80 :

x = 20/3

7) 5x+7 = 8x -71

(since vertically opposite angles equal and corresponding angles equal)

3x= 78 or x = 26

8) 7x-61 = 4x-7:3x= 54 orx = 18

9) 9x+25 = 13x-19

4x = 44: x=11:  17y+5 = 13(11)-19

y -7

10) 9x-36 =180 : x = 24: 8y+17 = 6(24)-7

8y =120: y =15

11) 7x-23 =49+3x(exterior angle of triangle)

Or 4x = 72: x=18 : 3x =11y-1

y =5

12) 5x-38 = 3x-4

2x = 34 or x =17

7y-20 = 5(17)-38

= 47

y = 67/7

4x - 2y ≤ 6      subtract 4x from both sides

-2y ≤ -4x + 6     change the signs

2y ≥ 4x - 6     divide both sides by 2

y = 2x - 3 - it's a linear function. We need only two points to plot the graph.

Choose any two values of x and calculate the values of y:

for x = 0 → y = 2(0) - 3 = 0 - 3 = -3 → (0, -3)

for x = 2 → y = 2(2) - 3 = 4 - 3 = 1 → (2, 1)

Step-by-step explanation:

The enlightenment emerged in 18th-century, which brought ideas that were deeply influenced by reason, empiricism and classics.  It restructured the old Greek and Roman ideas to make new inventions, and was changing ideas due to reasoning. It was the idea behind the invention of sculpting, a new way of passing ideas or information to people more than through paintings.

Enlightenment initially started with assembling of ordinary materials by a process termed sculptural construction, did not mean exactly the same thing to everybody.

During the enlightenment, artists placed more emphasis on science.

Artists during the Enlightenment shifted from Rococo to Neoclassicism and used their works to convey political messages.

Artists during the Enlightenment played a crucial role in spreading Enlightenment concepts and inspiring rational thinking.

the answer is 62 units because of the way the kite looks. a kite has 5 to 4 sides and if you divide that you will get sixty two units per unit.

The perimeter of kite ACBO is 62 units. Therefore, option C is the correct answer.

The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.

From the given kite ACBO, OB=7 uints and OC=25 units.

Here, ∠OBC=90° (Angle between radius and tangent is 90°)

By using Pythagoras theorem,  

BC²=OB²+OC²

25²=7²+OC²

625=49+OC²

OC²=625-49

OC²=576

OC=24 units

So, perimeter=2(a+b), where a and b are adjacent sides

= 2(7+24)

= 2×31

= 62 units

Therefore, option C is the correct answer.
