Find in degrees the numeric value of the acute angle of rotation that eliminates the product term from the equation 7x2+24xy−34x

lutik1710 [3]

Rotating the graph of $Ax^2+Bxy+Cy^2+Dx+Ey+F=0$ with $B\ne0$ counterclockwise by $\theta$ eliminates the $xy$ term, where $\cot2\theta=\frac{A-C}{B}.$ Plugging in, we have $\cot2\theta=\frac{7}{24},$ since $C=0.$ Solving, we have $\theta=\frac{1}{2}\cot^{-1}(\frac{7}{24})\approx\boxed{36.9^\circ}.$

27 1/5 over 4/5 as a unit rate

REY [17]

Answer:

$\frac{34}{1}$ or $34$

Step-by-step explanation:

we know that

To find the unit rate divide 27 1/5 by 4/5

but first

Convert mixed number to an improper fraction

$27\frac{1}{5}=27+\frac{1}{5}=\frac{27*5+1}{5} =\frac{136}{5}$

$\frac{136}{5}:\frac{4}{5}=\frac{136}{4}=\frac{34}{1}$

Each week carrie works 40 hours she spend 15% of her time at register

VLD [36.1K]

Please, share the goal of the problem. If Carrie works 40 hours per week and spends 15% of her time at the register, how much time does she NOT spend at the register?

Subtract 15% from 100%; the result is 85%. Now find 85% of 40 hours:

0.85(40 hours) = 34 hours.

Please note that I invented part of this problem. Next time, share all of the info so that someone can help you solve YOUR particular problem.
