Answer:

x = -95, y = 22.75, z = -6.625

Step-by-step explanation:

We start with the line that only has 1 variable, since that's easiest to solve.

2y + 162 = -28

2y = -190

y = -95

Then we go to the line that has 2 variables and substitute y with -95, since that's what y is equal to.

4x -95 = -4

4x = 91

x = 22.75

Then we do the last line with the answers we've gotten so far.

-14(22.75) - 3(-95) + 4z = 7

-318.5 + 285 +4z = 7

4z = -26.5

z = -6.625

n employee makes $161 per hour but is getting a 45% increase. What is his new wage per hour to the nearest cent?

Nadusha1986 [10]

Answer:

The answer is $234

Step-by-step explanation:

<h3><u>Given</u>;</h3>

An employee makes $161 per hour.
Increase of 45% every hour.

His new wage

First, find the 45% of $161.

161 × 45 ÷ 100 = $72.5

Now,

$161 + $72.5 = $233.5 = $234

Thus, His new wage will be $234

Find the mass of the triangle with vertices (1; 0; 0), (0; 2; 0), (0; 1; 1) if the density function is given by (x; y; z)

Luda [366]

Answer:

$=\frac{17}{3}$

Step-by-step explanation:

Density of a function is $\rho(x,y)=x^{2} +y^{2}$

I have drawn the right angle triangle for visualization

equation for the line passing through (1,0) and (0,4) is

$\frac{y}{4} =\frac{x-1}{-1}$

$y=4-4x$

= $\int_{0}^1\int_{0}^{4-4x} (x^{2}+y^{2})dydx$

= $\int_{0}^{1}(x^{2}+\frac{y^{3} }{3})dx$

= $\int_{0}^{1}(x^{2}(4-4x)+\frac{1}{3}(4-4x)^{3} )dx$

= $\int_{0}^{1}(\frac{-76}{3}x^{3} +68x^{2}-64x^{}+\frac{64}{3} )dx$

= $=(\frac{-76}{3} \frac{x^{4} }{4})+\frac{68}{3}x^{3}-32x^{2}+\frac{64}{3}x^{})$

$=\frac{17}{3}$

Solve the inequality: a - 4 <10

harkovskaia [24]

<h3>Answer: a < 14 (Choice B)</h3>

==================================================

Explanation:

Add 4 to both sides

a-4 < 10

a-4+4 < 10+4

a < 14

The reason why we add 4 to both sides is to undo the "minus 4" that's happening to the variable.

The part (aka "is") = 8 and the percent is 42, what is the whole (aka

marysya [2.9K]

Answer:

Step-by-step explanation:

If you simplify what the question is saying, it's basically..

8 is 24% of <u>what number?</u>

To find out, you can simply set up an equation.

((24% = 0.24 as a decimal (move the decimal point two times to the left))

8 = 0.24 x N (N is just the 'whole')

To solve, you just need to divide 8 ÷ 0.24. So, N = 33.333 repeating.

The question says to round to the nearest whole number, so the answer would just be 33.
