After working for 25 hours lammer made $375 after working 40 hours lammer made $600 predict how much will he make after 10 hours of work

Answers

Answer 1
25hr. 40h. 10hr

375$ 600$ x

25 . 40 . x = 1000
375 . 600 = 225000
225000÷1000
x = 225
Answer 2

Lammer will make $150 after working for 10 hours .

Calculating Earnings Based on Hours Worked

To predict how much Lammer will make after working 10 hours, we first need to determine his hourly wage. From the information given, we know:

After working 25 hours, Lammer made $375.After working 40 hours, Lammer made $600.

We can calculate his hourly wage as follows:

Hourly Wage = Total Earnings / Total Hours Worked

For both inputs, we observe:

$375 / 25 hours = $15 per hour$600 / 40 hours = $15 per hour

This indicates that Lammer's hourly wage is consistent at $15 per hour.

Now, to predict how much he will make after working 10 hours:

Earnings for 10 Hours of Work = Hourly Wage x Number of Hours

Earnings for 10 Hours = $15 x 10 = $150

Therefore, Lammer will make $150 after working 10 hours.

Use this equation to find dy/dx. 3y cos x = x2 + y2

Answers

Given: 3y cos x = x² + y²

Define [tex]y' = \frac{dy}{dx} [/tex]

Then by implicit differentiation, obtain
3y' cos(x) - 3y sin(x) = 2x + 2y y'
y' [3 cos(x) - 2y] = 2x + 3y sinx)

Answer:
[tex] \frac{dy}{dx} = \frac{2x+3y \, sin(x)}{3cos(x)-2y} [/tex]

wes has six errands to run (picking up the dry cleaning, going to the grocery store, getting gas, going to the bank, going to the library, and going to the video store). he only haves time to run 3 errands this afternoon. how many different combinations of three errands could he choose to run?

Answers

if you did 1*2*3*4*5*6 it's 720

Answer: 120 different combinations  .

Step-by-step explanation:

The combination of n things taking m things at a time is given by :-

[tex]C(n,m)=\dfrac{n!}{m!(n-m)!}[/tex]

Given : The total numbers of errands = 6

Now, the combination of 6 errands taking 3 at a time is given by :-

[tex]C(6,3)=\dfrac{6!}{3!(6-3)!}\\\\=\dfrac{6\times5\times4\times3!}{3!}=120[/tex]

Hence, he could choose to run 120 different combinations of three errands .

what is 150% as a fraction

Answers

150% means 150 out of 100 so find the GCF of both 150 and 100 and that would be 50 since it can go into both 150 and 100.

divide both the numerator and denominator by GCF

Simplify 

Answer: 3/2
To write .150 as a fraction you have to write .150 as the numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
.150 = .150/1 = 1.5/10 = 15/100

And finally we have: 
.150 as a fraction equals 15/100

In October Greg and Thomas had the same amount of money in their savings account in November Greg deposited $120 into his account Thomas increased the money in his account by 20% when they compare their bounces they found out they were still equal

Answers

assume the amount of money they both deposited in october is m.
in november, greg deposited 120$, so the total amount in his account became m+120
thomas increased his account by 20%, this meams that the amount of money in his account became: m+0.2m
since both values are still equal, we will equate the two equations and solve for m:
m+120 = m+0.2m
0.2m = 120
m = 600$

Any proposed solution of a rational equation that causes a denominator to equal​ _______ is rejected.

Answers

Answer:

Any proposed solution of a rational equation that causes a denominator to equal​ __ZERO__ is rejected.

Step-by-step explanation:

We will show this statement is true by an example:

Consider the expression :  [tex]\frac{x}{x-4}=\frac{x}{x-4}+4[/tex]

Now, solved the rational expression and check its proposed solution

[tex]\frac{x}{x-4}=\frac{x}{x-4}+4[/tex]

x cannot equal to 4, as it makes  both denominators equal to zero.

Multiply both the sides by (x-4),

[tex]\left ( x-4 \right )\cdot \frac{x}{x-4}=\left (x-4 \right )\cdot\left ( \frac{x}{x-4}+4  \right )\\[/tex]

Now, use the distributive property on Right hand side,

[tex]\left ( x-4 \right )\cdot \frac{x}{x-4}=\left (x-4 \right )\cdot \left ( \frac{x}{x-4} \right )+\left (x-4 \right )\cdot 4\\[/tex]

Simplify the above expression,

[tex]x=x+4x-16[/tex]

Combine like terms,

[tex]x-x-4x=-16[/tex]

[tex]-4x=-16[/tex]

Divide both sides by -4, we get

[tex]\frac{-4x}{-4}=\frac{-16}{-4}[/tex]

[tex]x=4[/tex].

As we know that x cannot equal to 4, replacing x=4 in the original expression causes the denominator equal to 0.

Check the solution: [tex]\frac{x}{x-4}=\frac{x}{x-4}+4[/tex]

Substitute the value of x=4 in the original expression,

[tex]\frac{4}{4-4}=\frac{4}{4-4}+4[/tex]

[tex]\frac{4}{0}=\frac{4}{0}+4[/tex]

Thus, 4 must be rejected as the solution, and the solution set is only 0.












Final answer:

A proposed solution of a rational equation that causes a denominator to equal zero is rejected because division by zero is not possible.

Explanation:

Any proposed solution of a rational equation that causes a denominator to equal zero is rejected. When the denominator of a rational equation is zero, the fraction becomes undefined because division by zero is not possible. In mathematics, division by zero is an undefined operation.
