-31 cannot equal 5 so the equation is false.

Answer:

n=8

Step-by-step explanation:

So, |n-3| means that the expression, n-3, is an absolute number (which is the difference from zero; just take off the negative sign if it has one)

Because the left side of the equation, 5, is a positive number, you would know that the equation can be solved by:

n-3=5       add 3 to both sides

n=8

You should also know that the absolute number (shown using | |) is not a negative number. (well, as long as the n is a real number)

Step-by-step explanation:

Solving for the circumference and using the formula for the circumference we got the radius as 74.95 feet

Given Data

1/4 of the circumference = 117.75 feet.

Let the circumference be x feet

1/4*x = 117.75

x/4 = 117.75

cross multiplying

x = 4*117.75

x = 471 feets

The expression for the circumference is given as

C = 2πr

471 = 2πr

Making r subject of formula we have

r =  = 471/2*3.142

r = 471/6.284

r = 74.95 feet

Step-by-step explanation:

When the two lines intersect, f(x) = h(x)

2x + 4 = -1x - 5

Rearranging like terms together

3x = -9

x = -3

Substituting back into h(x) for x = -3

y = h(3) = 2(-3) + 4 = -2

Answer:

35 students

Step-by-step explanation:

So if every 3 boys there is 4 girls you can solve that there is 5 times the amount of girls to get to 20. So to solve for the boys you do the same.

3 x 5 = 15

That means there are 15 boys and 20 girls but we want to know the total so what you do is just add 15+20=35

So 35 total students.

Answer:

67.3°C

Step-by-step explanation:

A = 25, T(0) = 100, T(1) = 90, find T(4)

dT/dt = -k(T - A)

d(T - A)/dt = -k(T - A)

d(T - A)/(T - A) = -k dt

ln(T - A) = lnC - kt

[tex]T(t) -A=Ce^{-kt}\\T(t) = A + Ce^{-kt} = 25 + Ce^{-kt}\\T(0) = 25 + C = 100\\C=75[/tex]

[tex]T(t) = 25 + 75e^{-kt}\\T(1) = 25 + 75e^{-k} = 90\\75e^{-k} = 65\\e^{-k} = \frac{65}{75}, k = ln\frac{75}{65} = 0.1431\\T(t) = 25+75e^{-0.1431t}\\T(4) = 25+75e^{-0.1431\times4} = 67.3[/tex]

Hello!

Let's consider what the question asks for

--> value of 'y' when 'x = 0'

   -7x + 3y = 30

Let's plug in '0' into x and solve for 'y'

  [tex]-7x+3y=30\\\\-7(0)+3y=30\\\\y=10[/tex]

Thus y = 10 when x = 0

Answer: 10

We are given the equation:

To find the value of y when x equals 0, we need to substitute 0 for x in the equation and solve for y:

Simplifying the equation:

Dividing both sides by 3:

Answer:

Step-by-step explanation:

Pay attention to the coordinates.

Because you are asked to find the perimeter, you need to determine the length of each side.

If the line is horizontal - you look at the x-coordinates. What's the distance between point A to point C?

For the diagonal sides you can use this formula:

d = Square root[( x 2 − x 1 ) ^2 + ( y 2 − y 1 ) ^ 2]

Answer: positive 3 is the final answer

Step-by-step explanation:

Answer:

9/3 or just 3

Step-by-step explanation:

First we need to recognize that points are given by numbers that represent the x and y coordinates (or locations) of the point. So in this problem, the first point (-1,5) has an x value of -1 and a y value of 5. Similarly the second point has an x value of -4, and a y value of -4.

Slope is defined as rise over run, or change in y (rise as it goes up or down)  over the change in x (or run as it moves left or right).

Change in x and y can be found by subtracting the first number from the second number.

So to calculate this, set up your equation like this:

[tex]\frac{5-(-4)}{-1-(-4)}[/tex]

After performing the subtraction, you should get:

[tex]\frac{9}{3}[/tex]

This further simplifies to 3.

Answer:

[tex]0.65[/tex]

Step-by-step explanation:

Given the following question

7 notepads cost $4.55 what's the unit price?

Unit price is price per unit, we find the price per unit by dividing the total cost of the notepads by the total amount of the notepads which is 7.

[tex]unitp=cost\div quantity[/tex]
[tex]7n=4.55[/tex]
[tex]4.55\div7=0.65[/tex]
[tex]=0.65[/tex]

The unit price of the seven notepads is "$0.65."

Answer:

32/75 in fraction form 0.426 in decimal

Step-by-step explanation:

0.64 2/3

convert tge decimal into a fraction = 64/100 reduce/simplify to 16/25

64 ÷ 4 = 16

___

100 ÷ 4 = 25

16/25 × 2/3 = 32/75

16 × 2 = 32

___

25 × 3 = 75

The simplified fraction form of .64 2/3 is 66/75. To convert the mixed number .64 2/3 to fraction form, we need to combine the whole number part and the fractional part.

The whole number part is 0.64, and the fractional part is 2/3.

To combine them, we multiply the whole number part by the denominator of the fraction and then add the numerator. Then, we put the result over the denominator.

Step 1: Convert the decimal to a fraction.

0.64 = 64/100

Step 2: Combine the whole number part and the fractional part.

0.64 2/3 = 64/100 + 2/3

Step 3: Find a common denominator (the least common multiple of 100 and 3 is 300).

0.64 2/3 = (64/100) + (200/300)

Step 4: Add the fractions.

0.64 2/3 = (64/100) + (200/300) = 264/300

Step 5: Simplify the fraction, if possible.

264/300 can be simplified by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 4.

264 ÷ 4 = 66

300 ÷ 4 = 75

So, the simplified fraction form of .64 2/3 is 66/75.

Answer:

b. 61 mph to 139 mph

Step-by-step explanation:

Chebyshev's theorem states that

For k> 1

1 - 1/k²

Where:

At least 75% or 3/4 of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.

At least 88.89% of 8/9 of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

From the question, we are told to find an interval that will contain the speeds of at least eight-ninths of the player's serves.

Mean (μ)= 100mph

Standard deviation (σ) = 13mph

At least 88.89% of 8/9 of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

Hence:

μ - 3σ

100 - 3(13)

= 100 - 39

= 61 mph

μ + 3σ

= 100 + 3(13)

= 100 + 39

= 139 mph

Therefore, the interval is between 61 mph to 139 mph. Option b is correct

Answer:

Fourth option

Step-by-step explanation:

The domain of a function is all possible x inputs for a function, on the contrary range of a function would be all possible y inputs for a function.

[tex]f(x)=-12x+15[/tex]

Since the function has all defined points, it basically means that the functions possible x inputs are "all real numbers" or the fourth option.

Using the definition of the absolute value function, it is found that the equation is written as: y = x + 4

It is the distance of a given point x to the origin(vertex of the function), hence the definition is as follows:

[tex]|x - a| = x - a, x \geq a[/tex]

[tex]|x - a| = -x + a, x < a[/tex]

Hence, considering that all expression are positive for x > 5, we have that:

Then, the expression is:

y = |x−3| + |x+2| − |x−5|

y =  x - 3 + x + 2 - x + 5

y = x + 4
