What is the value of x? (Triangles)

Answer:

9

Step-by-step explanation:

If the student recorded a temperature of 75 degrees Fahrenheit at hour 9 and 95 degrees Fahrenheit at hour 13. The rate of change between these temperatures will be 5 Fahrenheit per hour.

It is defined as the change in values of a dependent variable with respect to the independent variables.

It is given that, A student recorded a temperature of 75 degrees Fahrenheit at hour 9 and 95 degrees Fahrenheit at hour 13.

The term "rate of change" refers to the pace at which one quantity changes with respect to another.

The rate of change is the ratio of temperature to the time elapsed,

Rate of Change = change in temperature/time elapsed

Rate of Change = (95°F - 75°F) / (13 -9) hour

Rate of Change =20 / 4

Rate of Change = 5 Fahrenheit per hour

Thus, if the student recorded a temperature of 75 degrees Fahrenheit at hour 9 and 95 degrees Fahrenheit at hour 13. The rate of change between these temperatures will be 5 Fahrenheit per hour.

Answer:

Much obliged to you for your inquiry, your inquiry is: The measure of green growth in a blossom, P, can be displayed by the condition P = t4 + 6t3 + 7t2 + 8t, where t is estimated in weeks. When will the number of inhabitants in green growth be more prominent than 500?

The equation for the first option would be

Where "x" is the number of copies and y the cost.

The second equation will be

If we graph both equations we have

As we can see, they will be equal in terms of cost with 2 copies. The cost will be 50.

We can see it at the intersection of the two graphs! we can also do it with algebra, if the costs are equal (same "y") we can say

The number of copies is 2.

The vertices are: (0, 0), (0, 3) and (7, 0) are identified in the graph

The regions that satisfy one or more inequalities can be seen when there are inequalities on a graph.

These inequalities are frequently linear and can be represented by straight line graphs.

To solve the inequalities, plot straight line graphs with either a solid line or a dashed line using the linear equations.

A solid line indicates that the line is present.

The bounded region in question is a triangle in the second quadrant. The line y = 2x + 6 has intercepts (0, 6) and (-3, 0), so revolving the triangle about the x-axis forms a cone with height 3 and whose circular base has radius 6. Its volume would then π/3 • 6² • 3 = 36π ≈ 113.1 units³.

But you're probably supposed to use calculus. Using the disk method, the integral for the volume is

\(\displaystyle V=\pi\int_{-3}^0 (2x+6)^2\,\mathrm dx\)

\(\displaystyle V=\pi\int_{-3}^0(4x^2+24x+36)\,\mathrm dx\)

\(V=\pi\left(\dfrac43x^3+12x^2+36x\right)\bigg|_{-3}^0=\boxed{36\pi}\)

2x+6 is the required weight.

The weight of an object is defined as the force acting on the object due to gravity. It is a scalar quantity. Weight is measured in newtons.

In Physics, the gravitational force with which the earth attracts all the masses to its center is called weight.

In the given question,

Let the weight of an object is x.

6 pounds more than twice the weight means the required weight of an object will be the 2×weight of the object(x) + 6 pounds.

Therefore,

2x+6 is the required weight of the object.

Answer:

becuase 2*3 is 6, and 2*4 is 8, and when you simplfy it is 1 and 1/2, which in decimal form is 1.5, making it less than 2

Answer:

Is 2/4 smaller than 2/3? These are the same questions with one answer.

To get the answer, we first convert each fraction into decimal numbers. We do this by dividing the numerator by the denominator for each fraction as illustrated below:

2/4 = 0.5

2/3 = 0.667

Then, we compare the two decimal numbers to get the answer.

0.5 is less than 0.667.

Therefore, 2/4 is less than 2/3 and the answer to the question "Is 2/4 less than 2/3?" is yes.

Answer:

1 f(3) = 3*2-4*3 +4=-2

f(x+3) = (x+3)*2 - 4*(x+3) +4

=-2(x+1)

Step-by-step explanation:

1 f(3) = 3*2-4*3 +4=-2

f(x+3) = (x+3)*2 - 4*(x+3) +4

= 2x +6 - 4x -12 + 4

The linear equation that describes this situation is:

y = 2500 + 300*x

A general linear equation is written as:

y = ax + b

where a is the slope and b is the initial value.

Here we know that she starts with 2,500 points in the game, and then she wins 300 points for every minute.

Then the initial value is 2,500, and the slope is 300, then we can write the linear equation:

y = 2500 + 300*x

Answer:

x=40

Step-by-step explanation:

80°+(2x+20)°= 180°... (co-interior angles are supplementary)

2x=180 - 80 - 20

2x=80

(divide both sides by the coefficient of x which is 2)

x=80÷2

x=40

Check:

(2x+20) must be equal to 100

Let x=40

Therefore :

2X40+20

=100

Answer:

x = 40

Step-by-step explanation:

These angles are known as same-side interior angles. They are supplementary angles meaning they have a sum of 180°.

\(2x+20+80=180\\2x+100=180\\2x=80\\x=40\)

The sum of the x-coordinates of the points that lie in the region above the straight line y = 2x + 7 in coordinate plane is thirty-eight.

A point lies above the straight line , y = 2x + 7 in co-ordinate plane . If its y -coordinate is greater than two times its x-coordinate plus 7. Now, we are checking the each ordered pair one by one ,

(i) plug x = 3 and y = 10

2x + 7 = 3×2 + 7 = 13 > 10

(ii) plug x = 6 in 2x+7

=> 2× 6 + 7 = 19 < 20

(iii) x = 12

=> 2x + 7 = 2× 12 + 7 = 31 < 35

(Iv) x = 18

=> 2x + 7 = 2× 18 + 7 = 43 > 40

(v) x = 20

2x + 7 = 2×20 + 7 = 47 < 50

We see (6, 20) , ( 12,35) and (20,50) satisfy this condition. Now, we determine the sum of x-coordinates . The sum of the x-coordinates of these points is 6 + 12 + 20 = 38 . So, required sum of x-coordinates is 38.

The value of x using the theorem of intersecting secants is 10

From the question, we have the following parameters that can be used in our computation:

intersecting secants

Using the intersecting secants equation, we have

8 * (8 + x) = 6 * (6 + 18)

Evaluate the like terms

So, we have

8 * (8 + x) = 6 * 24

Divide both sides by 8

8 + x = 6 * 3

So, we have

8 + x = 18

Subtract 8 from both sides

x = 10

Hence, the value of x is 10

3/5 part of 60 CD's were gifts.

That makes:

The total amount Debra ended up paying for the equipment was $28,541.60 and the amount of interest Debra paid on the loan was $14,041.60

(a) To find the total amount Debra ended up paying for the equipment (including the down payment and monthly payments), we need to add the down payment to the total amount of the loan, and then add the total amount of the monthly payments made over the two years.

Total amount of the loan = $14,500 - $1,300 (down payment) = $13,200

Total amount paid = Down payment + Total amount of the loan + Total amount of monthly payments

Total amount paid = $1,300 + $13,200 + ($585.04 x 24) [since there are 24 monthly payments in 2 years]

Total amount paid = $1,300 + $13,200 + $14,041.60

Total amount paid = $28,541.60

Therefore, the total amount Debra ended up paying for the equipment (including the down payment and monthly payments) was $28,541.60.

(b) To find the amount of interest paid on the loan, we need to subtract the total amount borrowed from the total amount paid, and then subtract the down payment. This will give us the total amount of interest paid over the two years.

Total interest paid = Total amount paid - Total amount borrowed - Down payment

Total interest paid = $28,541.60 - $13,200 - $1,300

Total interest paid = $14,041.60

Therefore, the amount of interest Debra paid on the loan was $14,041.60.
