A field's length l(x), in feet, can be represented by the expression x+10 and its width w(x), in feet, can be represented by the expression x+15. Which function represents its area?

A) x^2+25x+150
B) 4x+50
C) 2x+25
D) x^2+10x+150

Answers

Answer 1

Answer:

A) x^2+25x+150

Step-by-step explanation:

Area = length x width

A = (x + 10) x (x + 15)

A = x^2 + 25x + 150

Okay so, to get C you add the ones inside the triangle together.

42+58=100 Then the last angle will be 80, because when you add the three inside the triangle, you should get 180

42+58+80=180

To get D, you have to subtract 180 and 58, because 58+d will be a straight angle.

180-58=121

To get B and A, you would also have another straight angle (c, b, and a)

180-80=100

I believe that B=A, so, with the remaining 100, both A and B equal 50.

50+50+80=180

Does this help??

Answer:

a° = 58°

b = 42°

c° = 80°

d° = 122°

Step-by-step explanation:

d° can be found because a straight line has an angle of 180°.

180° - 58° = 122°

Because the angles of a triangle add up to 180°, we can find c°

58° + 42° = 100°. 180° - 100° = 80°

You can find a° subtracting 180 and d°, which is 122. 180° - 122° = 58°

You can do the same thing for b°. 180° - 42° = 138°. 180° - 138° = 42°

You can check this because b° + c° + a° should equal 180°.

58° + 42° + 80° = 180°

I hope this helps :)

In a recent year, 23% of all college students were enrolled part-time. If 6.2 million college students were enrolled part-time that year, what was the total number of college students?

Answers

Answer:

17,222,222

Step by Step Solution:

If 26% equals 6,200,000, then

1% equals 6,200,000/23, and

100% equals (6,200,000/23)*100 = 17,222,222.222222222222222222222222

Hence, there were about 17,000,000 (seventeen million) students.

To be a bit closer to the number, there where about 17,222,222 students.

Find the Area and Perimeter of the figure below.
6 cm
4 cm
2 cm
3 cm

Answers

Answer:

Area: 40cm^2

Perimeter:24cm

Step-by-step explanation:

Area: First of all, you can see that the missing height of the shape is 3cm. By adding 4 and 3, you get 7. Then, by multiplying 7 and the length of the shape (6cm), you get 42cm^2. After that, you have to multiply 2cm and 3cm to get the blank area in the bottom right corner to get 6cm^2. Finally, you can subtract 42cm^2(the whole area) by 6cm^2 (the blank area) to get 40cm^2.  

Perimeter: Okay! To get the first missing measurement (the one on the left), you have to imagine 4cm being moved to that side. 3cm is parallel to the missing blank space under the 4cm. This means you have to get 7cm (you add 4 and 3). To get the other missing measurement (bottom of the shape) you must see that 6cm would be parallel to the bottom. Since 2cm is also parallel to the bottom, you would have to subtract 2 from 6 to get the bottom of the shape's length, which is 4. Finally, you would have to add 6, 4, 3, 2, 4 and 7 together to get 24cm.  

At the beginning of the school year, Jamie had $500 in her savings account. She wants to have at least $200 left in the account at the end of the school year. Each week, she withdraws $30 for spending money. To determine how many weeks she can spend $30, Jamie wrote and solved this inequality. 500 − 30x ≥ 200 −500 −500 −30x ≥ −300 x ≥ 10 Review Jamie's work. What was her error?

Answers

Answer:

Step-by-step explanation:

Given the inequality solved by H=Jamie expressed as:

500 − 30x ≥ 200

We need to calculate the range of x of the inequality to determine the number of weeks she can spend $30 as shown:

500 − 30x ≥ 200

Subtract 500 from both sides

500 − 30x - 500≥ 200 - 500

− 30x ≥ -300

Divide both sides by -30

− 30x/-30 ≥ -300/-30

x ≤ 10 (note that the inequality sign changes after dividing both sides by a negative sign)

Jamie's error was that she didn't change the sense of inequality after dividing both sides by -30 hence rendering her solution incorrect

Hence the number of weeks is less than or equal to 10.

Answer:

Answer is B

Step-by-step explanation:

Jamie should have reversed the inequality when using the division property of inequality. is the right answer hope it helps

Create the polynomial which has roots 3and 2

Answers

Answer:

f(x) = x² - 5x + 6

Step-by-step explanation:

Given a root of a polynomial x = a then the factor is (x - a)

Here the roots are x = 3 and x = 2 , thus the corresponding factors are

(x - 3) and (x - 2)

The polynomial is then the product of the factors, that is

f(x) = (x - 3)(x - 2) ← expand using FOIL

      = x² - 5x + 6

Since this polynomial has answers 3 and 2, we can set up the equation (x-3)(x-2) = 0

That’s already our answer, but if you want it in standard form, We can use FOIL to multiply the 2 expressions:
(x-3)(x-2)
=x^2-3x-2x+6
=x^2-5x+6
