Answers

Answer:

51 cubic units

Step-by-step explanation:

[tex]3x+2y+z=12\\\Rightarrow z=12-3x-2y[/tex]

Now we integrate over volume integral over the range [tex]R = \{(x,y) | 0\le x \le {1}, -{2} \le y \le {4} \}[/tex]

[tex]V=\int_0^1\int_{-2}^4 12-3x-2y dydx\\ =\int_{-2}^4 12y-3yx-y^2|_4^{-2} dx\\ =\int_{0}^1 12\times4-3\times4x-16-[12\times-2-3\times-2x-4]dx\\ =\int_{0}^1 60-18xdx\\ =60x-9x^2|_{0}^1\\ =60-9\\ =51\ \text{cubic units}[/tex]

Why can't a whole number be irrational? Please dumb it down for me

Answers

Answer and Step-by-step explanation:

A whole number isn't irrational because it is a whole number. Confused? Most likely.

A whole number is any of the numbers {0, 1, 2, 3, ...} etc. There is no fractional or decimal part. And no negatives. Example: 5, 49 and 980 are all whole numbers.

An Irrational Number is a real number that cannot be written as a simple fraction. Irrational means not Rational. The irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers.

These are both real numbers because they don't go through the 4th wall (of science/math)

Keith bought 8 new baseball trading cards to add to his collection. The next day his dog ate half of his collection. There are now only 30 cards left. How many cards did Keith start with?
please help!!!

Answers

Answer:

52 cards

Step-by-step explanation:

call the amount he started with " x "

then he bought 8 cards

so the new equation is

x+8

then he lost half of his cards

so now the equation is

(x + 8 )/2

that amount to 30 cards as per what is given in the problem

so now the equation is

( x + 8 )/2 = 30

solve using inverse operations and simplifying

( x + 8 )/2 = 30  

         *2    *2

x + 8 = 60

   -8     -8

x = 52

the slope of a hill 3/190. The Hill has a ride of 400m. What is the horizontal distance covered by the hill?​

Answers

Answer:

its 5

Step-by-step explanation:

The hill with a rise of 400m and a slope of 3/190 covers approximately 25333.33 meters horizontally.

Slope is a term used to describe how steep or inclined a line is on a graph. It shows the proportion of the rise to the run or vertical change, between any two points on a line. The slope is a fundamental idea in geometry, algebra and calculus; it shows how much the line rises or falls for each unit of horizontal distance. A slope of zero denotes a horizontal line while positive slopes denote upward inclines, negative slopes denote downward inclines, and vice versa.

Slope = rise / run

Given that the slope of the hill is 3/190 and the rise is 400m, we can set up the equation:

3/190 = 400 / run

run = 400 / (3/190) = 400 × (190/3)

      = 400 × 63.33 ≈ 25333.33 meters

the horizontal distance covered by the hill is approximately 25333.33 meters.

Erica chooses a number. She divides it by four then subtracts 11. She then divides this
result by two. Her answer is 12.5. What was the number she started with?

Answers

Step-by-step explanation:

Let x be the number.

Divide it by 4

x/4

Subtract 11

x/4 - 11

x-44/4

Divides this result by 2

x-44/4 ÷ 2

x-44/4 × 1/2

x-44/8

Her answer is 12.5

x-44/8 = 12.5

x-44 = 12.5 × 8

x = 100 + 44

x = 144

Hence,
