What’s the rate of change of the table above? A) -1/3 B) 1/2 C) -1/4 D) 1/5

insens350 [35]

answer is option D

because you can divide them like

$\frac{2}{10} = \frac{1}{5} \\ \\ \frac{4}{20} = \frac{1}{5} \\ \\ \frac{6}{30} = \frac{1}{5} \\ \\ \frac{8}{40} = \frac{1}{5}$

so the option is D

Pam and her sister have a pattern of saving money. Pam saved 40 dollars and her brother saved 100 dollars.

Keith_Richards [23]

Answer:

true

Step-by-step explanation:

Pam saved 40

her bro saves 100

let us take this as ration 40 is to 100 which can also be written in fractional for like 40/100 now we simplify it how by dividing both by 20 so (40/20)/(100/20) which will give 2/5 which can be written as 2 is to 5 so this is true

Answer:

It's either 400 or 1,200.

Just need the equation

Anna007 [38]

$a. $ x = -2\\b. $ x = \frac{3}{2} \\c. $ x = 0\\d. $ x = -\frac{1}{5}$

Each of the equations can be solved as shown below:

a. $3x + 7 = - x - 1$

$3x + 7 + x = - x - 1 + x$ (addition property of equality)

$4x + 7 = - 1\\4x + 7 - 7 = -1-7$ (Subtraction property of equality)

$4x = -8\\\frac{4x}{4} = \frac{-8}{4}$ (Division property of equality)

$x = -2$

b. $1 - 2x + 5 = 4x - 3\\$

Add like terms

$6 - 2x = 4x - 3\\\\6 - 2x - 6 = 4x - 3 - 6$ (Subtraction property of equality)

$- 2x = 4x - 9\\-2x - 4x = 4x -9 - 4x$ (Subtraction property of equality)

$-6x = -9 \\\frac{-6x}{-6} = \frac{-9}{-6}$ (Division property of equality)

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

c. $4x - 2 + x =-2 + 2x\\$

$5x - 2 = -2 + 2x\\5x - 2x = -2 + 2\\3x = 0\\ x = \frac{0}{3} \\x = 0$

d. $3x - 4 + 1 = - 2x -5 + 5x\\$

$3x - 3 = - 7x -5\\3x + 7x = 3 - 5\\10x = -2\\x = \frac{-2}{10} \\x = -\frac{1}{5}$

The value of x in each equation are:

$a. $ x = -2\\b. $ x = \frac{3}{2} \\c. $ x = 0\\d. $ x = -\frac{1}{5}$

I need help on number 18

zloy xaker [14]

Answer:

Volume = 35185.8 $km^{3}$

Step-by-step explanation:

Recall the formula for the volume of a cone: $Volume = \pi R^{2} \frac{h}{3}$

Where R is the radius of the cone's circular base (in your case half of 80 km,(that is 40 km)

And h stands for the height of the cone (in your case 21 km)

We replace such in the formula and calculate its final value:

$Volume = \pi 40^{2} \frac{21}{3} = \pi 1600 \frac{21}{3} = \pi 1600 (7) = 35185.83772...$

We round it to the number of decimals your problem request (let's say to one decimal) and also include the cubic units:

Volume = 35185.8 $km^{3}$
