3 0

Answer:

The answer is 2000 yuan.

Step-by-step explanation:

Devise a proportion for this, and then cross-multiply. I believe that is the easiest way.

\frac{1}{0.15}  =  \frac{x}{300}  \\ 0.15x = 300 \\ x =  \frac{300}{0.15}  \\ x =  \frac{30000}{15}  \\ x =  \frac{10000}{5}  \\ x = 2000

What is the length of a diagonal of a rectangle with a length of 8 meters and a width of 6 meters
RSB [31]

Answer:

10 m

Step-by-step explanation:

If we draw the diagonal of the rectangle, we form a right triangle where the diagonal is the hypotenuse and the legs are 6 and 8.

This is a well-known Pythagorean triple, which gives the diagonal to be 10 m.

Solve the system of equations below by graphing.
Katen [24]

(0.5, 1.3) is the correct answer

Step-by-step explanation:

Given equations are:

y = 4x-0.8\ \ \ Eqn1\\2x+y-2.3=0\ \ \ Eqn2

As we can see that the given equations are linear equations which are graphed as straight lines on graph. The solution of two equations is the point of their intersection on the graph.

We can plot the graph of both equations using any online or desktop graphing tool.

We have used "Desmos" online graphing calculator to plot the graph of two lines (Picture Attached)

We can see from the graph that the lines intersect at: (0.517, 1.267)

Rounding off both coordinates of point of intersection to nearest tenth we get

(0.5, 1.3)

Hence,

(0.5, 1.3) is the correct answer

Pls help :Find the missing side or angle.<br> Round to the nearest tenth.
Nitella [24]

Answer:

C° = 71.6056

Step-by-step explanation:

Law of Cosines: c² = a² + b² - 2abcosC°

Step 1: Plug in known variables

29² = 30² + 15² - 2(30)(15)cosC°

Step 2: Evaluate

841 = 900 + 225 - 900cosC°

-59 = 225 - 900cosC°

-284 = -900cosC°

71/225 = cosC°

cos⁻¹(71/225) = C°

C° = 71.6056

And we have our answer!
