Your answer would be 18.39

And here's why:

Behind the decimal your numbers are in the following places.

The (3) is in the tenths place.
The (8) is in the hundredths place.
And the (6) is in the thousandths place.

Whatever number is AFTER the place your rounding, is going to help you out.

If the number is 1-4, you round down.

Find the slope of the line passing through the points (-4, -4) and (2, 5)

Sliva [168]

Answer: The slope is 3/2

Step-by-step explanation:

To find the slope, you need to find the difference between the y coordinates and divide it by the difference in the x coordinates.

The y coordinates are -4 and 5

The x coordinates are -4 and 2

-4 -5 = - 9

-4 - 2 = -6

-9/-6 = 3/2

A parking lot charges $3 to park a car for the first hour and $2 per hour after that. If you use more than one parking space, th

Vikki [24]

Given, a parking lot charges $3 for first hour and $2 per hour after that.

So for t hours, the parking lot charges $3 for the first hour and after first hour there is $(t-1)$ hours left.

So for $(t-1)$ hours it will charge $2 per hour.

The charges for $(t-1)$ hours = $ $2(t-1)$ .

Total charges for t hours for one car = $ $(3+2(t-1))$

Now for the second car, it will charge 75% of the first car.

So the charges for second car

=$[ $(3+2(t-1))(75/100)$ ]

=$ $0.75(3+2(t-1))$

There are 3 cars. That parking charges for the third car is also 75% of the first car.

So for third car the parking charges are same as for the second car.

Total parking charges for 3 cars

= $ $(3+2(t-1))+(0.75(3+2(t-1))+(0.75(3+2(t-1))$

= $ $(3+2(t-1))+(0.75)(2(3+2(t-1))$

We have got the required answer here.

The correct option is option C.

In triangle EFG , EF=FG . EF= 6X-10 , EG =2X+14, and FG =3X+11. find EF .

jarptica [38.1K]

Since EF=FG, you can set 6x - 10 = to 3x + 11

$6x -10 = 3x +11$

Then add like terms

$6x - 3x = 11+10$

so, $3x = 21$

Now you can divide by 3 to get $x = 7$ :)

then put it back into $6x - 10$

$6(7) - 10 = EF$

so, $EF = 32$
