Answer:

if it was 102 when he woke

e up and lowered then it will be 99 degree fahrenheit then

Final answer:

Steve's temperature decreased by 3 degrees from the original 102 degrees F, which means his temperature two hours later was 99 degrees F.

Explanation:

The student's question involves a basic mathematical operation, specifically subtraction, used to determine a change in temperature over time. Steve originally has a temperature of 102 degrees Fahrenheit. After two hours, his temperature has decreased by 3 degrees.

To find the new temperature, we subtract the decrease from the original:
102 degrees F - 3 degrees F = 99 degrees F.

So, Steve's temperature two hours later would be 99 degrees Fahrenheit.

The circumference is:

[tex]C = 43.98\ ft[/tex]

The area is:

[tex]A=153.94\ ft^2[/tex]

Step-by-step explanation:

The circumference of a circle is calculated using the following formula

[tex]C = \pi d[/tex]

Where C is the circumference and d is the diameter of the circle.

In this case we know that

[tex]d = 14\ ft[/tex]

Therefore the circumference is:

[tex]C = \pi *14[/tex]

[tex]C = 43.98\ ft[/tex]

The area of a circle is calculated using the following formula

[tex]A=\pi(\frac{d}{2})^2[/tex]

Where d is the diameter of the circle.

Then

[tex]A=\pi(\frac{14}{2})^2[/tex]

[tex]A=\pi(7)^2[/tex]

[tex]A=49\pi[/tex]

[tex]A=153.94\ ft^2[/tex]

The circumference of the flower bed is approximately 43.96 feet and the area is approximately 153.86 square feet.

The gardener's circular flower bed has a diameter of 14 feet. The formula to calculate the circumference of a circle is C=πd where 'd' represents the diameter. Therefore, by substituting the given diameter, we get C = 3.14 * 14 = 43.96 feet approximately.

The area of the circle can be calculated by using the formula A=πr², where 'r' represents the radius of the circle. The radius is half of the diameter, that is 14/2 = 7 feet. So, A = 3.14 * 7² = 153.86 square feet approximately.

Answer:

-4

Step-by-step explanation:

Technically, the negative sign is treated as multiplying by -1, which is then separate from the 2.  This equation can also be rewritten as [tex]-1 * 2^2[/tex], which would be simplified to [tex]-1 * 4[/tex] and then [tex]-4[/tex].

It depends on how the parenthesis is like. -(2)^2 will equal -4 while (-2)^2 equals 4. But the answer will most likely be 4 because they tend to make sure to put parenthesis if they want the answer to be -4. (Calculators are programmed differently which is why you're getting mixed answers.)

Answer:

The correct answer option is C. (0, c).

Step-by-step explanation:

We are given an isosceles trapezoid with the coordinates of three of its vertices and we are to find the coordinates of Z.

Z is a point on the middle of one of the sides of the trapezoid.

Since Z lies on the horizontal x axis, therefore its x coordinate is 0 while the y coordinate can be seen from the vertex exactly at its right which is c.

Z (0, c)

==============================================

Explanation:

Note how the point (a,0) mirrors over the y axis to land on (-a,0)

A similar action will happen as we go from te point (b,c) to point W (-b, c), due to this figure being isosoceles.

The x coordinate changes from positive to negative. The y coordinate stays the same.

The point Z is the midpoint of the upper segment which spans from (-b,c) to (b,c)

Apply the midpoint formula to find where Z is located.

Add up the x coordinates and divide by 2: x = (-b+b)/2 = 0/2 = 0

Add up the y coordinates and divide by 2: y = (c+c)/2 = 2c/2 = c

So the midpoint is located at (x,y) = (0, c) which is where point Z is located as well.

Side note: it might help to replace the letters a, b and c with actual values, just so the problem is more concrete.

Step-by-step explanation:

The nonpermissible replacement of the variable in an expression is the value of x that will make the denominator of the expression zero.

Answer:

25 gallons.

Step-by-step explanation:

The container that holds the water for the football team is 1/2 full.

After pouring out 5 gallons of water, it is 3/10 full.

The proportion that was poured out is [tex]\frac{1}{2}[/tex] - [tex]\frac{3}{10}[/tex] = [tex]\frac{2}{10}[/tex] = [tex]\frac{1}{5}[/tex]

[tex]\frac{1}{5}[/tex] of the water in the container is equal to 5 gallons

The container therefore holds: 1 × 5 ÷ [tex]\frac{1}{5}[/tex] = 5 × 5 = 25 gallons.

Final answer:

The total capacity of the container is calculated to be 25 gallons, found by using the information that 1/2 to 3/10 of the capacity equals a 5 gallon difference.

Explanation:

We have been given that the container is initially 1/2 full and becomes 3/10 full after pouring out 5 gallons of water.

To find out the total capacity of the container, we can set up a proportion where the difference between the two fractions (1/2 and 3/10) represents the 5 gallons removed.

First, we find a common denominator for the two fractions, which is 10. Now we can say:

The difference between 5/10 and 3/10 is 2/10, which equates to the 5 gallons poured out. Thus, 2/10 of the container's capacity is 5 gallons, and we can find the full capacity (10/10) by multiplying the 5 gallons by 5 (since 2 × 5=10).

So, the container's total capacity is 5 gallons × 5 = 25 gallons.

Answer: The percent of students have scored between 60 and 65 points is 34.13%

Step-by-step explanation:

Given : The points obtained by students of a class in a test are normally distributed with a mean of 60 points and a standard deviation of 5 points.

i.e. [tex]\mu=60\ \ \ \sigma=5[/tex]

Let x denotes the points obtained by students of a class in a test .

Now , the probability that the students have scored between 60 and 65 points :-

[tex]P(60<x<65)=P(\dfrac{60-60}{5}<\dfrac{x-\mu}{\sigma}<\dfrac{65-60}{5})\\\\= P(0<z<1)\ \ \ [\because z=\dfrac{x-\mu}{\sigma}]\\\\= P(z<1)-P(z<0.5)\ \ \ [\because\ P(z_1<Z<z_2)=P(Z<z_2)-P(Z<z_1)]\\\\=0.8413-0.5=0.3413[/tex]

[tex]=34.13\%[/tex]

Hence, the percent of students have scored between 60 and 65 points is 34.13%.

The total amount that all three friends have is $84.

Let's assume that Ami, Jan, and Toy have x, y, and z dollars respectively. After the first redistribution, we know that:

x - a = 2(y + z)

y + a = 2(x + z)

z + a = 2(x + y)

where a is the amount of money that Ami gives to Jan and Toy.

Solving these equations, we get:

x = 5z - 4a

y = 5z - 6a

z = z

After the second redistribution, the new amounts are:

x + b = 2(y + c)

y - b + c = 2(x + c)

z + b + c = 2(x + y)

where b is the amount that Jan gives to Ami and Toy, and c is the amount that Toy gives to Ami and Jan.

Solving these equations, we get:

x = 14c

y = 11c

z = 6c

Finally, after the third redistribution, the new amounts are:

x + 2d = 2(y + 2d)

y + 2d = 2(x + 2d)

z - 2d + 2c = 2(x + y)

where d is the amount that Toy gives to Ami and Jan.

Solving these equations, we get:

x = 8d

y = 10d

z = 18d

Since we know that z = $36, we can solve for d and get d = $2. Therefore, the total amount that all three friends have is:

x + y + z = 8d + 10d + 36 = $84.

ANSWER

The system consists of parallel lines. Both lines have the same slope.

EXPLANATION.

The first equation is

[tex]y = \frac{1}{3} x - 4[/tex]

This equation is in the slope-intercept form.

The second equation is

[tex]3y - x = - 7[/tex]

We write this one too in slope-intercept form so that we can make comparison.

[tex] \implies \: y = \frac{1}{3} x - \frac{7}{3} [/tex]

We can see that both equations have slope

[tex]m = \frac{1}{3} [/tex]

This means the two lines are parallel.

The two lines have different y-intercepts.

Two parallel lines with different y-intercepts will never meet.

The lines will never intersect.

Answer:

The true statements are:

- The system consists of parallel lines

- Both lines have the same slope

Step-by-step explanation:

* Lets talk about the solution of the linear equations

- There are three types of the solutions of the system of linear equations

# If the two lines intersect each other, then there is one solution

- The equations are ax+ by = c , dx + ey = f

# If the two lines parallel to each other, then there is no solution

- The equations are ax+ by = c , ax + by = d in its simplest form ,

  where a is the coefficient of x , b is the coefficient of y and

  c , d are the numerical terms

# If the two lines coincide (over each other), then there are infinite

   solutions

- The equations are ax+ by = c , ax + by = c in its simplest form, where

  a is the coefficient of x , b is the coefficient of y and c is the

  numerical term

* Lets solve the problem

∵ The system of equation is:

   y = 1/3 x - 4 ⇒ (1)

   3y - x = -7 ⇒ (2)

- Lets put equation (1) in the form of equation (2)

∵ y = 1/3 x - 4 ⇒ multiply both sides by 3

∴ 3y = x - 12 ⇒ subtract x from both sides

∴ 3y - x = -12

∴ Equation (1) is 3y - x = -12

∵ Equation (2) is 3y - x = -7

∵ The coefficients of x and y in the two equation are equal

∵ The numerical terms in the two equations are not equal

∴ The equations have no solution because their lines are parallel

∵ The parallel lines have same slope

* The true statements are

- The system consists of parallel lines

- Both lines have the same slope

f(x) is the total number of hours overall that he has worked out.

x would be the number of weeks he works out.

You would multiply x ( number f weeks he works out) by 7 and then add that to the hours he already worked out (15) which will give you the total hours (f(x)).

Answer:

In this case, x represents "week", because they problem says that he exercises 7 hour per week, being week an unknown number because we don't how much time Luke is gonna keep exercising. Si, 7x represents the total amount of hours per week after the first 15 hours.

Similarly, f(x) represents the total amount of hour from the beginning, before the first 15 hours. The difference between x and f(x) is that the first one represents hours after the 15 hours, and the second one represents the total amount of hours, including before the 15 hours.

It's important to notice that 15 is not multiplied by a variable, it's because those 15 hours are already achieve, we don't if those where monthly or weekly, but the fact that they already happened means that they can't change, that's why the don't have a variable.
