[tex]▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ { \huge \mathfrak{Answer}}▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ [/tex]
As we know that :
[tex] {i}^{2} = i \times i = - 1[/tex]so, over here
[tex] - 4i \times i[/tex][tex] - 4 {i}^{2} [/tex]plugging the value of i² as -1

How much of the circle is shaded? Write your answer as a fraction in simplest form? 3/7 and 1/3 isn't shaded
Answer:
[tex]total = 1 \\ \frac{1}{2} + \frac{1}{7} + x = 1 \\ \frac{1}{7} + x = 1 - \frac{1}{2} \\ \frac{1}{7} + x = \frac{1}{2} \\ x = \frac{1}{2} - \frac{1}{7} \\ x = \frac{7 - 2}{7 \times 2} \\ x = \frac{5}{14} \\ \\ shaded \: portin \: = \frac{5}{14} \\ thank \: you[/tex]
Answer:
[tex]\frac{5}{14}[/tex]
Step-by-step explanation:
Half the circle ( to the left ) is partly shaded
shaded part = [tex]\frac{1}{2}[/tex] - [tex]\frac{1}{7}[/tex] = [tex]\frac{7}{14}[/tex] - [tex]\frac{2}{14}[/tex] = [tex]\frac{5}{14}[/tex]

Ryan is driving on a long road trip. He currently has 13 gallons of gas in his car. Each hour that he drives, his car uses up 1.25 gallons of gas. How much gas would be in the tank after driving for 4 hours? How much gas would be left after t hours?
Answer: gas left after 4 hours :8
Gas left after t hours: 13-1.25t
Step-by-step explanation:
The gas left after 4 hours will be 8 gallons and expression for the gas left after t hours will be 13 - 1.25 t.
It is given that Ryan has 13 gallons of gas in his car and car uses 1.25 gallons of gas per hour.
We have to find out the amount of gas left after 4 hours and expression for the gas left after t hours.
What do you mean by algebraic expressions ?
The algebraic expressions are those which are made up of variables, constants and algebraic operations i.e., addition, subtraction, etc.
As per the question ;
Ryan has 13 gallons of gas in his car.
The gas used per hour = 1.25 gallons
The gas used by car in 4 hours will be ;
= 1.25 × 4
= 5 gallons
So ,
The gas left after 4 hours will be equal to ;
= 13 - 5
= 8 gallons
Also ;
The gas left after t hours can be represented by equation ;
= 13 - 1.25 t
Thus , the gas left after 4 hours will be 8 gallons and expression for the gas left after t hours will be 13 - 1.25 t.

I recently had work done on my car. The estimate was $234.78 but the actual was $365.99.
What is the relative error in the estimate?
Round to 2 decimal places.
Answer:
35.85%
Step-by-step explanation:
first, find the difference between the real value and the estimated value:
365.99 - 234.78 = 131.21
now divide the difference by the real value:
131.21 / 365.99 = 0.358507
now multiply 0.358507 by 100 to get a percentage, then round to 2 decimals:
35.85%

Answer:
1, 4, 5, 6
Step-by-step explanation:
1 - Division is considered a fraction, subjected to fraction as division also. Since - 5/17 is basically considered -5/-17 (via 4), 1. is a choice.
4 - As explained, - 5/17 is -5/-17, so this is also a choice.
5,6 - Whether the negative symbol is in the numerator and/or denominator, it is officially thought overall to be - 5/17.
The volume of a cube is found by:
1. l x w x h
2. l x w
3. w x h
Answer:
1)
Step-by-step explanation:
l x w and w x h are all formula for a rectangle, not a cube.
For instance, let's take l x w. If we change the height it will definitely change the volume, but according to 2) it won't. So, 2 is wrong.
We can do the same process for 3) to show it's wrong.
So, the answer is not 2) or 3), so it must be [tex]\boxed{1)}[/tex]
