Since you've told us that this is an isosceles triangle, we know that the 'legs' have equal length.  So we can write

                                                      x + 1 = -x + 7

Add 'x' to each side:                  2x + 1 =       7

Subtract  1  from each side:      2x       =       6

Divide each side by  2 :                x      =       3

Now, if the length of the base is   3x - 3 ,
that length is

                                   3(3) - 3  =  6  .

Tony made $396 for 18 hours of work at the same rate how many hours would he have to work to make $198
tresset_1 [31]

Answer:

9 hours.

Step-by-step explanation:

So, first, you have to determine what he makes per hour to make this as easy as possible. You need to first do 396 divided by 18, which gives you 22. He makes 22$ an hour. Next, now that you know what he makes, you can do 198 divided by 22, and that'll show how long he has to work to make that amount of money.

Hope this helped. Please mark this brainliest if you think this helped. Let me know if you need anymore help and I am more than happy.

poizon [28]

Answer:

Step-by-step explanation:

Volume of cylinder can be calculated by using the formula V= pir^2h

Where r is radius of cylinder and h is the height.

A cylinder with radius 1 inch and height of 9 inch is given.

r=1,h=1,π=3.14.

Substituting the given values :

V=πr2h=π·12·9≈28.27433

Volume of cylinder rounded to nearest tenth is 28.27 cubic inches .
