How do i solve -6+2(-2+8v-6v)

Answers

you can simplfy but not solve

distributive preopotty
a(b+c)=ab+ac

fist simlify all inside parenthasees
-2+8v-6v
-2+2v

now we have
-6+2(-2+2v)
distribute
2(-2+2v)=2*-2+2*2v=-4+4v

now we have

-6-4+4v
-10+4v is simplfied form

20% of 150 is what number?

Answers

Answer=30

20%=20/100=0.2

150*.20=30

If you would like to know how much is 20% of 150, you can calculate this using the following steps:

20% of 150 = 20/100 * 150 = 2 * 15 = 30

1. a researcher tagged 40 giant turtles in 2008. In 2009, she returned and captured 50 turtles, 16 of which were tagged. In 2010 she returned again and captured 30 turtles, 8 of which were tagged. A. Use a proportion to estimate the turtle population for 2009
B. Use a proportion to estimate the turtle population for 2010

Answers

Given:
2008 - 40 giant turtles tagged
2009 - 50 turtles capture where 16 were tagged
2010 - 30 turtles capture where 8 were tagged

2009:
40/x = 16/50
40*50 = 16x
2000 = 16x
2000/16 = x
125 = x

2010:
40/x = 8/30
40*30 = 8x
1200 = 8x
1200/8 = x
150 = x

What is true regarding chords and diameters of circles?A. both cords and diameters have two endpoints on a circle. Diameters must intersect the center of a circle.

B. both chords and diameters have two endpoints on a circle. Chords must intersect the center of a circle

C. Chords have two endpoints on a circle. Diameters have one endpoints on a circle and one at the center

D. Chords have one endpoint on a circle and one at the center. Diameters have two endpoints on a circle

Answers

Answer:

The correct answer is A.

Step-by-step explanation:

The only way to answer this question is to check the definitions of chord and diameter.

A chord is a segment with endpoints on the circle. In the attached figure the segments CD and GH are chords.

Now, notice that according to the given definition the segment EF is also a chord, but with the special characteristic that the center of the circle, denoted by A, it is on the segment. This ‘‘special’’ chords that contains the center of the circle are called diameter.

Sometimes the diameters are also called the larger of the chords.

the answer choice will be A
