Two angles are complementary. The measure of one angle is 3° more than one-half of the measure of the other. Find the measure of each angle.

Answer:

-5, 3

Step-by-step explanation:

3) 10+3n=20+5n Set up the problem

        -3n       -3n Subtract 3n from both sides to get n on one side of the equation.

    10     =20-2n

    -20     -20 Subtract 20 from both sides to isolate n

     -10    =2n

      /2       /2 Divide both sides by 2 to isolate n

      -5    =   n

4) 18=2(b+6) Write down problem

   18=2b+12 Distribute

    -12     -12 Subtract 12 from both sides to isolate b

    6=2b

     /2/2 Divide both sides by 2 to isolate b

     3=b

Answer:

3) 3x+10 = 5x+20

=> 3x-5x= 20-10

=> -2x= 10

=> x = 10/-2

=> x= -5

4) 2(b+6) = 18

=> 2b +12 = 18

=> 2b = 18-12

=> b= 6/2

=> b = 3

Step-by-step explanation:

18x²-8

= 2(9x²-4)

= 2(3x+2)(3x-2)

18x² - 8

Common factor is 2.

=》18x² - 8

=》2 (9x²- 4) [option C].

Answer:

5) First you have to find x, then use it with supplementary angles theorem.

6) STQ = 150˚

Step-by-step explanation:

To find x, add (2x+8), (71-x), and 90˚ together to add up to 180˚ (those three angles are supplementary):

(2x+8) + (71-x) + 90 = 180˚

x + 169 = 180

Then solve for x:

x = 11

You can check if x is right by inputing it back into the two equations and see if all three of the angle measures together equal 180˚.

Now, you only need m∠MTS (2x+8) to find m∠STQ...

m∠MTS + m∠STQ = 180˚ because they are supplementary angles.

Input the found x to find m∠MTS:

(2(11)+8) = 30

Subtract 30 from 180 to find m∠STQ:

180 - 30 = 150

m∠STQ = 150˚

Answer:

Y= -x-4

(-1,-3)

Step-by-step explanation:

Simply plot the point (-5,1) and draw in a line with a slope of -1. Take the slope of this line and the point it crosses the y-axis and use them to set up slope intercept form.

Confused by what you mean

Answer:

always increasing

Step-by-step explanation:

When you look at the graph from left to right on the x-axis the y-axis is always increasing in value.

Answer:

One of the benefits of Cavalieri's principle is that it allows us to determine the volume of an oblique prism (or oblique cylinder). When dealing with two prisms (or two cylinders), if the base areas are equal and the heights are equal, then the volume is V = Bh regardless of the overall shape.

( i cant see the answers well so estimate to the one that applies)

Answer:

written in y=mx+b form: y=−5x−5

Written in standard form: 3y+15x=−15

Written in slope intercept form: y=−5x−5

Step-by-step explanation:

that right answer

Answer:

its 16

Step-by-step explanation:

area for a triangle is 1/2 the base times the height.

IN order to find out the base you need to multiply the area by two and then divide by 42 to find the base. X will represent the base

so

336 *2 = 42x

672= 42x

672/42=x

16 = x

Volume of Sphere

= 4/3πr³

= (4/3)(3.14)(60/2)³

= 113,040ft³.

The diameter of the sphere is 60 ft

Volume of sphere = 4/3πr³

= (4/3)(3.14)(60/2)³

= 113,040ft³

The volume of the given sphere is 113,040ft³

1/2 is a rational number.

Step-by-step explanation:

A rational number can be expressed as a ratio of two numbers. 1/2 is a ratio.

It is also a real number, however you do not list that as a category, so from what you listed, it is only a rational number.
