What is 12.09 - 03.37

Answer:

103.5

Step-by-step explanation:

The area for the trapezoid is Area = ((a+b)/2)h where a = base 1, b = base 2, and h = height. 15 + 8= 23, and divided by 2 is 11.5. 11.5 x 9 = 103.5. Hope it helps.

Answer:

n = 11/3

Step-by-step explanation:

n = certain number

6n - 1 = 21

6n = 22

n = 22/6 or 11/3

Answer:

A. Right angle  -- if you multiply the slopes of 2 intersecting lines and you "-1" then the lines are perpendicular - in this case the line in quadrant 3 has a slope of "1" and the line in quadrant 4 has a slope of "-1", hence their product is "-1" and the angles formed at the intersection of the lines are right angles.

Step-by-step explanation:

Answer: 7 hours

Step-by-step explanation:

Let the number of hours used be represented by h.

Since a bike cost 8$ plus 3$ Per hour and Ravi spent 29$ for a bike rental.

This can be represented in an equation as:

8 + 3h = 29

Collect like terms

3h = 29 - 8

3h = 21

h = 21/3

h = 7 hours

Ravi rented the bike for 7 hours

Answer:

Lindsey earned a commission of $6.23

Step-by-step explanation:

Given that:

Commission rate = 5%

Amount of merchandise bought by customer = $124.50

Commission amount = 5% of 124.50

Commission amount = [tex]\frac{5}{100}*124.50[/tex]

Commission amount = 0.05 * 124.50

Commission amount = $6.225

Rounding off to nearest cent

Commission amount = $6.23

Hence,

Lindsey earned a commission of $6.23

Answer:

D. 5(z/x)^10

Step-by-step explanation:

15/3 = 5

z^-5 gets moved to the top, and made positive z^5

x^-3 gets moved to the bottom, and made positive x^3

z^5 + z^5 = z^10

x^7 + x^3 = x^10

5(z/x)^10

Answer:

19.2

Step-by-step explanation:

The length of the diagonal of the screen is 19.2 inches

What is the diagonal of a rectangle?

The diagonal of a rectangle is calculated by the formula

From the Pythagoras Theorem , The hypotenuse² = base² + height² , and

Diagonal of a Rectangle = √ ( Length )² + ( Width )²

Given data ,

The length of the screen of the monitor is L = 15 inches

The width of the screen of the monitor is W = 12 inches

Now ,

The diagonal of the screen of the monitor is calculated by ,

Diagonal of a Rectangle = √ ( Length )² + ( Width )²

So ,

Substituting the value of length L and width W , we get

Diagonal of the screen = √ ( 15 )² + ( 12 )²

                                      = √ ( 225 ) + ( 144 )

                                      = √ 369

                                      ≈ 19.209 inches

Therefore , the diagonal of the screen is 19.209 inches

Hence , The length of the diagonal of the screen is 19.2 inches

Step-by-step explana

Diameter of a circle = 28 m

Then, radius of the circle will be :

[tex] = \tt \frac{diameter}{2} [/tex]

[tex] =\tt \frac{28}{2} [/tex]

[tex] = \tt14 \: m[/tex]

Thus, the radius of this circle = 14 m

Area of circle :

[tex] = \tt\pi {} {r}^{2} [/tex]

[tex] =\tt 3.14 \times 14 \times 14[/tex]

[tex] = \tt3.14 \times 196[/tex]

[tex] = \tt615.44 \: {m}^{2} [/tex]

Thus, the area of this circle = 615.44 m²

Circumference of circle :

[tex] = \tt2\pi r[/tex]

[tex] =\tt 2 \times 3.14 \times 14[/tex]

[tex] = \tt87.92 \: m[/tex]

The circumference of this circle = 87.92 m

Therefore, the area of this circle = 615.44m² and the circumference of this circle = 87.92m

Given:

The system of equations:

[tex]y=2x+4[/tex]

[tex]y=-\dfrac{10}{3}x+\dfrac{76}{3}[/tex]

To find:

The sum of the x- and y-values in the solution to the system of equations.

Solution:

We have,

[tex]y=2x+4[/tex]                ...(i)

[tex]y=-\dfrac{10}{3}x+\dfrac{76}{3}[/tex]                  ...(ii)

From (i) and (ii), we get

[tex]2x+4=-\dfrac{10}{3}x+\dfrac{76}{3}[/tex]

[tex]2x+\dfrac{10}{3}x=\dfrac{76}{3}-4[/tex]

[tex]\dfrac{6x+10x}{3}=\dfrac{76-12}{3}[/tex]

Multiply both sides by 3.

[tex]16x=64[/tex]

Divide both sides by 16.

[tex]x=\dfrac{64}{16}[/tex]

[tex]x=4[/tex]

Putting x=4 in (i), we get

[tex]y=2(4)+4[/tex]

[tex]y=8+4[/tex]

[tex]y=12[/tex]

The solution of system of equations is (4,12).

[tex]x+y=4+12[/tex]

[tex]x+y=16[/tex]

Therefore, the sum of the x- and y-values in the solution to the system of equations is 16.

Answer:

128 : 1

Step-by-step explanation:

Given that:

The length of an alligator = 12.8 feet.

The length of its replica toy = 3 2/5 inches = 1.2 inches

Since;

1 foot = 12 inches

Then the scale used is:

(12.8 × 12 ) inches = 1.2 inches

153.6 inches = 1.2 inches

Thus, the scale used is 128 : 1

Answer:

(-5,2) (-7,0)

Step-by-step explanation:

Answer:

yes, (0,0) is a solution for the system of equations.

Step-by-step explanation:

y < -x + 3 ,we would then plug in the ordered pair which changes that equation to 0 < 0 +3 (which is just 0 < 3) and that is true.

Then we plug in the ordered pair for the second equation, which changes it to  0 < 2 or 0 < 0 + 2.

Now, since the inequalities are true, the ordered pair works for the system.

Step 2: Solve for x

Step 3: Solve for y

Answer:

Yes

Step-by-step explanation:

To check proportionality :

35 α 1000

35 = 1000k

k = constant of proportionality ;

Divide both sides by 1000 to obtain k

35 / 1000 = 1000k / 1000

0.035 = k

For the ratio Given :

Ratio of 7 parts of salt and 200 parts of water

7 : 200

7 / 200

= 0.035

Since,

k = 0.035 ; 7 / 200 = 0.035

Hence, a proportional relationship exists.
