The remaining 2 debts have to add up to a cetain number which I represent as x.
476.25 - 93.22 - x = 0
x = 383.03
The correct two debts should add up to -383.03.
Therefore the answer is B. -66.72 and -316.31

Find f(-5) if f(x)=[x+1]

Mademuasel [1]

Answer: -5

Step-by-step explanation:

square brackets mean that you need to select an integer part from the number that does <u>not exceed the original number</u>, that is, if we have a number, that is, if [5,1]=5 or [-5,1]=-6 ; curly brackets highlight the fractional part {} $\displaystyle\ \Large \ \boldsymbol{Rules: } \\\\\\\boldsymbol{ if \ x >0 => [x]=x-\{x\}} \\\\\\\boldsymbol{if \ x [x]=x-1+\{x\}} \\\\\\then \ \ f(-5)=[-5+1]= [-4]=-4-1+0=\boxed{-5}$

A worker gets $9/hr for a regular work day and $13.50/hr for additional hours. If he was paid $114.75 for an 11hr work day, how

Anika [276]

1. I did 9x8 since you usually work 8 hours a day but did not give answer, so I add or subtracted 0.5 to 8.

2. i did 9*7.5=67.5 , keep in mind that he worked for 11 hrs that day so 11-7.5=3.5 hours left

3. then I subtracted 67.5 from 114.75 and got 47.25

4. I divided 3.5 by 47.25 and got 13.5

A plane flies due south for 600 miles. It turns and flies 250 miles ,35 degrees east of south. How far is the plane from it’s or

Mariulka [41]

The distance of plane from the origin is 357.14 miles

<u>Explanation:</u>

Given:

distance traveled southwards, y = 600 miles

Distance traveled east of south, z = 250 miles

Angle, θ = 35°

Distance of plane from the origin, x = ?

The figure is attached for reference:

tan θ = Perpendicular / base

tan θ = distance travelled east of south / x

tan 35° = 250 / x

we know,

tan 35° = 0.7

So,

$0.7 = \frac{250}{x} \\\\x = \frac{250}{0.7} \\\\x = 357.14 miles$

Therefore, the distance of plane from the origin is 357.14 miles
