The next two numbers are 60 and 600. The pattern is to multiply the number by 10.
Hope that helped.

I need help with #10!

Answer: 6 years old.

Step-by-step explanation:

For this exercise let "x" represents your present age.

According to the information provided in the exercise, you know that In three years, Chad will be three times your present age.

Then, your age in three years can be represented with the following expression:

$x+3$

Knowing at that time Chad's age will be three times yours and you will be half as old as old as Chad, you can write the following equation to represent this situation:

$x+3=\frac{3x}{2}$

Therefore, the final step is to solve for "x" in order to find its value.

You get that this is:

$2(x+3)=3x\\\\2x+6=3x\\\\6=3x-2x\\\\x=6$

Which of the following angles can be trisected using only a compass and straightedge?

ZanzabumX [31]

I'm pretty sure it is C. 45 because compass and straightedge is a right angle or an acute angle and 45 is less than a right angle

Please help me with these 5 questions!

Answer:

Part 2) Option D. yes; k = 1/4 and y = 1/4x

Part 6) Option D. y = 1/5x-1

Part 8) Option C. line b

Part 11) Option D. -1/5

Part 15) Option A. line a

Step-by-step explanation:

Part 2) we know that

A relationship between two variables, x, and y, represent a directly variation if it can be expressed in the form $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem the line passes through the origin

therefore

Yes. y varies directly with x

Let

A(4,1)

The constant k is equal to

$k=y/x$

substitute

$k=1/4$

the equation is equal to

$y=(1/4)x$

Part 6) we know that

The y-intercept of the trend line is -1 (For x=0)

The slope of the trend line is positive

The x-intercept of the trend line is 5 (For y=0)

therefore

the equation is equal to

$y=(1/5)x-1$

Part 8) we have

$y+4=-\frac{2}{3}x$

This is the equation of a line into point slope form

The slope is negative $m=-2/3$

Pass through the point (0,-4) ----> y-intercept

The x-intercept is equal to

$0+4=-\frac{2}{3}x$

$x=-4*3/2=-6$

therefore

Is the line b

Part 11)

What is the slope of the line through the points (–2, –1) and (8, –3)?

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{-3+1}{8+2}$

$m=\frac{-2}{10}$

simplify

$m=-\frac{1}{5}$

Part 15) we have

$y=3x-2$

The slope is positive $m=3$

The y-intercept is -2 (For x=0)

The x-intercept is (For y=0)

$0=3x-2$

$3x=2$

$x=2/3$

therefore the line is a

What is the volume of a sphere with a radius of 9.2 cm, rounded to the nearest tenth of a cubic centimeter?

chubhunter [2.5K]

Answer:

3262.9 cm^3

Step-by-step explanation:

Formula =

$\frac{4}{3} \times \pi r ^{3}$

Pi = 3.145

So,

$\frac{4}{3} \times 3.145 \times 9.2 ^{3} \\ = 3262.183595 \\ = 3262.9 cm^{3}$

Here you go
