For example, the same angles could give you a triangle with sides 7-12-13, 35-60-65, or any other multiple. Find the third angle by subtracting from 180°. Then use the Law of Sines (28)★ twice to find the second and third sides. Use the Law of Cosines (31)★ to find the third side.Feb 19, 2018

A) .05n + .10d + .25 q = 10.30
B) d +2 = q
C) n = 3q
Substituting equations B and C into A
A) .05*3q + .10(q-2) + .25 q = 10.30
A) .15q + .1q -.2 + .25q = 10.30
A) .50q = 10.50

Which of the following statements is true about the graph and the shading of the inequality
andreyandreev [35.5K]

Answer:

The graph is a solid line, and the shading is above the line.

Step-by-step explanation:

Given

x + y \ge 1

Required

Describe the graph of the inequality

We have:

x + y \ge 1

Subtract x from both sides

y \ge 1-x

The sign \ge implies that the graph has a solid line

The sign \ge which means greater than or greater also implies that the upper region is shaded

O GEOMETRY Volume of a sphere The radius, R, of a sphere is 8.3 mm. Calculate the sphere's volume, V. Use the value 3.14 for , a
ioda

ANSWER

2393.9 mm³

EXPLANATION

The volume of a sphere of radius R is,

V=\frac{4}{3}\pi R^3

In this case, the radius of the sphere is 8.3 mm. Using π = 3.14, the volume is,

V=\frac{4}{3}\cdot3.14\cdot8.3^3mm^3=2393.881573\text{ }mm^3\approx2393.9\text{ }mm^3

Hence, the volume of the sphere is 2393.9 cubic millimeters, rounded to the nearest tenth.

Find the distance between (-7,-2) and (11,3)
jarptica [38.1K]

Answer:

The answer is

<h2>\sqrt{349}  \:  \: units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

<h3>d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }   \\</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-7,-2) and (11,3)

The distance between the points is

<h3>d =  \sqrt{ ({ - 7 - 11})^{2} +  ({ - 2 - 3})^{2}  }  \\  =  \sqrt{ ({ - 18})^{2} +  ({ - 5})^{2}  }  \\  =  \sqrt{324 + 25}  \\</h3>

We have the final answer as

<h3>\sqrt{349}  \:  \: units</h3>

Hope this helps you
