Mathematics
1 answer:
Aleonysh [2.5K]4 years ago

Answer:

A

Step-by-step explanation:

We graph two variable inequalities like we graph line equations. First, read the inequality as y\geq mx+b where m is the slope and b is the y-intercept. Here b= 2. Go to the y-axis and mark a point on 2. From here, go up 3 and over 2. Mark the point at (2, 5).  Since the inequality does not have an "equal to" draw a dashed line is drawn between the points with arrows on either end. To finish, test an (x,y) point to determine what makes the inequality true.  

Choose any (x,y) point not on the line. Say (0,0).

y < \frac{3}{2}x + 2\\0

Is the statement true? Yes. This means shade this side of the line.

Solution A matches this.

Given that LM and LN are tangent to the circle and that the measure of angle MLN = 75.86, find the measure of arc MN.
siniylev [52]

we know that

The measure of the external angle is the semidifference of the arcs that it covers

so

∠MLN=(1/2)*(mayor arc MN-minor arc MN)

Let

x------> minor arc MN

major arc MN=360-x

substitute in the formula above

∠MLN=(1/2)*(mayor arc MN-minor arc MN)

75.86=(1/2)*(360-x-x)------> 151.72=(360-2x)------>360-151.72=2x

x=104.14°

therefore

the answer is

the measure of arc MN (minor arc) is 104.14°

Find the area. Do you multiply all sides?
arlik [135]

Answer:

Step-by-step explanation:

I think you are to assume that this is a trapezoid and that the top right angle symbol is missing.

Area = (b1 + b2 ) *  h /2

Givens

b1 = 2

b2 = 6.2

h = 3

Solution

Area = (2 + 6.2)* 3 / 2           Combine what is inside the brackets

Area = 8.2 * 3 / 2                  Divide by 2

Area = 4.1 * 3                         Combine

Answer: Area = 12.3

How many 1-inch cubes do you need to create a cube with an edge length of 5 inches?
Kruka [31]
Number of 1 inch cubes:

Volume of the 1 inch cubes = 1*1*1 = 1 cubic inches.

Volume of the 5 inch cubes =  5*5*5 = 125 cubic inches.

Number =  Volume of the 5 inch cubes / Volume of the 1 inch cubes

            =  125 /1 = 125.

125 of the 1-inch cubes.
