What is 3 feet less than the Legnth
three less than the length

The range of the function y = -3, graphed over the domain {x | -8 < x < 8}, is a singular value, which is y = -3.

The question asks for the range of the function y = -3 which is graphed only over the domain {x | -8 < x < 8}. This function is a horizontal line, which means that for any value of x within the domain, the value of y will always be -3.

Therefore, the range of this function is simply the single value y = -3, because no matter what x-value we have (as long as it's between -8 and 8), the y-value remains constant at -3.

Final answer:

The volleyball court is 16 meters long, which was calculated by using the formula for the perimeter of a rectangle and the given width of 9 meters.

Explanation:

To find the length of the volleyball court, we need to use the formula for the perimeter of a rectangle which is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. Since we know the perimeter is 50 meters and the width is 9 meters, we can substitute these values into the formula to solve for the length l.

First, we calculate the total contribution of the width to the perimeter, which is 2w, so 2 times 9 meters = 18 meters. We then subtract this from the total perimeter to find the combined contribution of both lengths: 50 meters - 18 meters = 32 meters. Finally, we divide by 2 to find the length of one side: 32 meters / 2 = 16 meters.

Therefore, the volleyball court is 16 meters long.

  x = -3 or +2

Step-by-step explanation:

Such an equation resolves into two equations. The argument of the absolute value function can be either positive or negative, so there is one equation for each case.

4x +2 = 10

  4x = 8 . . . . subtract 2

  x = 2 . . . . . divide by 4

4x +2 = -10

  4x = -12 . . . subtract 2

  x = -3 . . . . . divide by 4

The two solutions are x=-3 and x=2.

Answer:

Sometimes true.

Step-by-step explanation:

The statement is sometimes true and sometimes false depending on the values of x and y.

Here's an example that shows it to be true.

|x+y|=|x|+|y|

Let x = 5 and y = 6.

|x+y|=5 + 6 = 11

|x|+|y| = |5| + +|6| = 5 + 6 = 11

In this case, both sides equal 11, and the expression is true.

Here's an example that shows it to be false.

|x+y|=|x|+|y|

Let x = -5 and y = 5.

|x+y|= |-5 + 5| = |0| = 0

|x|+|y| = |-5| + |5| = 5 + 5 = 10

The left side equals 0, and the right side equals 10. The sides are different, and the expression is false.

Answer:

Therefore NFC won 28 games and AFC won 25 games.

Step-by-step explanation:

i) let the number of Super Bowls won by NFC be x

ii) let number of Super Bowls won by AFC be y

iii) therefore it is given that  x + y = 53

iv) and also it is given that x = y + 3

v) substituting the equation in iv) into the equation in iii) we get

  (y +3) + y  =  53    ⇒  2y = 50   therefore y = 25.

vi) substituting the value of y from v) into the equation iv) we get

    x  = 25 + 3 = 28.

Therefore NFC won 28 games and AFC won 25 games.

To solve this mathematics problem, we formulate an equation based on the information that total Super Bowls were 53 and NFC won 3 more than AFC. By solving the equation, we find that NFC won 28 games and AFC won 25 games.

To solve this problem, let's start with the total number of games, which is 53. If the NFC has won 3 more Super Bowls than the AFC, that means the number of games won by both conferences adds up to 53. Let's denote the number of games won by the AFC as 'x'. So, the equation will be:

By combining like terms, we get:

Subtracting 3 from both sides, we have:

Finally, when we divide by 2, we solve for x:

This means that the AFC has won 25 games, and the NFC, having won 3 more, has won 28 games.

Answer:

240.3

Step-by-step explanation:

Remember SohCahToa for the trig. ratios. You always divide two sides.

'o' is opposite side. 'a' is adjacent side. 'h' is hypotenuse side.

Using alternating angles you can find the angle I marked blue (see diagram below). Because the 31° is parallel to the bottom side of the triangle, you can use alternating angles (Z pattern), where both 'insides' of the Z have the same measure.

The blue angle will be our angle of reference (angle we are talking about) represented by this symbol θ.

Since we need to find 'y', the opposite side, and we know 400ft is the adjacent side, use the tangent ratio.

tanθ = opposite / adjacent

tan31° = y / 400ft           Substitute what you know.

y = (400ft)tan31°          Isolate 'y'. Multiply 400ft and tan31°.

y = 240.344......ft      Exact answer on calculator

y ≈ 240.3ft      Answer rounded to nearest tenth

The nearest tenth is the first decimal. Since the second decimal is '4 or less', you round down, keeping the digit of the first decimal the same.

If the second digit was '5 or more', then you would round up.

To find the percent error, calculate the absolute difference between the estimated height and the actual height, and divide it by the actual height. Finally, multiply the result by 100 to get the percentage.

To find the percent error, we need to calculate the absolute difference between the estimated height and the actual height, and then divide it by the actual height.

Finally, we multiply the result by 100 to get the percentage.

Step 1: Determine the difference between estimated and actual height.

Difference = Actual height - Estimated height

Difference = 54 inches - 50 inches

Difference = 4 inches

Step 2: Calculate the absolute value of the difference.

Absolute value of the difference = |4 inches|

Absolute value of the difference = 4 inches

Step 3: Divide the absolute difference by the actual height and multiply by 100% to get the percent error.

Percent Error = (Absolute difference / Actual height) × 100%

Percent Error = (4 inches / 54 inches) × 100%

Percent Error ≈ 7.41%

Therefore, the percent error in your estimation of your friend's height is approximately 7.41%.

Answer:

14.

Step-by-step explanation:

The number of neutrons = the mass number - atomic number

= 27 - 13 = 14.

The correct answer is that Aluminium (Al), with an atomic number of 13 and a mass number of 27, has 14 neutrons.

To find the number of neutrons in an atom, one subtracts the atomic number (which is the number of protons) from the mass number (which is the sum of the number of protons and neutrons).

For Aluminium:

- The atomic number (Z) is 13, which means it has 13 protons.

- The mass number (A) is 27, which means the total number of protons and neutrons is 27.

The number of neutrons (N) can be calculated using the formula:

[tex]\[ N = A - Z \][/tex]

[tex]\[ N = 27 - 13 \][/tex]

[tex]\[ N = 14 \][/tex]

Therefore, Aluminium has 14 neutrons.

There are 4 periods of 2 hour sleep and 1 period of 1 hour sleep = 4*2(60) + 1(60) ... So 540/600 = 54/60 = 9/10 = 90% of the time asleep.

Answer:

87.5%

I am not sure how to set this up....so I am just gonna try to figure this a different way....without any formula

8 p.m - 10 pm.......awake for 15 minutes

10 pm - 12 am......awake 15 minutes

12 am - 2 am.......awake 15 minutes

2 am to 4 am.....awake 15 minutes

4 am to 6 am....awake 15 minutes

so from 8 pm to 6 am....that is a total of 10 hrs.....and in those 10 hrs, the baby was awake 5(15) = 75 minutes.....change 10 hrs to minutes.....1 hr = 60 min...so 10 hrs = (10 * 60) = 600 minutes

so in 600 minutes, the baby was awake 75 minutes.....that means the baby was asleep (600 - 75) = 525 minutes

525/600 = 0.875 = 87.5% <=== baby was asleep

or maybe this way....for every 2 hrs, the baby was awake 15 minutes....means the baby was asleep (120 - 15) = 105 minutes.

2 / 105 = 10 / x

2x = 1050

x = 1050/2

x = 525 minutes.....so the baby was asleep 525 minutes out of 600 minutes.

525/600 = 0.875 = 87.5%

​

The system of equations is as follows:

Equation 1: Total nails from small boxes = 150s

Equation 2: Total nails from large boxes = 400l

Equation 3: Total boxes = s + l

Equation 4: Total nails = 150s + 400l = 1950

To determine the number of small boxes and large boxes the contractor purchased, we can set up a system of equations. Let's define the variables: let "s" represent the number of small boxes and "l" represent the number of large boxes.

Now, let's break down the information given into equations:

Equation 1: The total number of nails from the small boxes is 150 times the number of small boxes, which is 150s.

Equation 2: The total number of nails from the large boxes is 400 times the number of large boxes, which is 400l.

Equation 3: The total number of boxes is the sum of small and large boxes, so the total boxes are s (number of small boxes) plus l (number of large boxes).

Given that the contractor bought 2 more small boxes than large boxes and the total number of nails purchased is 1950, we can express this as an equation:

4. Equation 4: The total number of nails purchased is 1950.

Now, we can write the system of equations:

Equation 1: 150s

Equation 2: 400l

Equation 3: s + l

Equation 4: 150s + 400l = 1950

In this system, Equation 1 represents the total number of nails from the small boxes, Equation 2 represents the total number of nails from the large boxes, Equation 3 represents the total number of boxes, and Equation 4 represents the total number of nails purchased.

To find the solution, we can solve this system of equations using various methods, such as substitution or elimination, to determine the values of "s" and "l," representing the number of small and large boxes the contractor purchased, respectively.

Proportional: Mike, a plumber charges $5 per hour for his service.

Non-proportional: Mike charges a initial cost of $10 plus $3 for each hours of service.

Step-by-step explanation:

Let us assume that Mike, a plumber charges $5 per hour for his service.

So, the number of hours (h) of service and the total charge (C) are proportional, which is  

C(h) = 5h ....... (1)

If the condition changes like, Mike charges an initial cost of $10 plus $3 for each hour of service.

Here, the equation that models the situation is  

C(h) = 10 + 3h .......... (2)

Now, relation (1) is non-proportional.  (Answer)

Final answer:

Real-world examples of directly proportional relationships include the relationship between distance and time at a constant speed, and cost and weight of fruit. These relationships become nonproportional when a base charge or flat fee is introduced, respectively.

Explanation:

Two real-world quantities that have a proportional linear relationship are speed and distance traveled in a given amount of time, assuming constant speed. For example, the farther you travel at a steady speed, the longer it takes. This relationship can be represented by y = kx, where y is the distance, x is the time, and k is the constant speed.

To make this relationship nonproportional, we could introduce a starting fee or base charge, making the total cost not just dependent on the distance but also an additional amount. Another example of a directly proportional relationship is the cost of fruit, where cost and weight are proportional (y = kx). By adding a flat packaging charge regardless of weight, the relationship between cost and weight becomes nonproportional.
