Find what that area is
22*66=1452

5 times of that is
1452*5=7260


s=seconds

(22+33s)(66+33s)=7260
1089s^2+2904s+1452=7260
minus 7260 from both sides
1089s^2+2904s-5808=0
factor or use quadratic formula
(363)(x+4)(3x-4)=0
set each to zero
x+4=0
x=-4, false, it is increasing, not decreasing

3x-4=0
3x=4
x=4/3

answer is 4/3 seconds

Can you help me please everyone is ignoring my questions
galben [10]

Answer:

A= 37 degrees

C= 43 degrees

Step-by-step explanation:

Hey there!

So this question looks a lot more complicated than it really is.

Complementary angles are the same.

Supplementary angles add up to 180 degrees or in other words a straight line.

If A and B are complementary and B equals 37 degrees, than A is also 37 degrees.

To find C, all we would do is subtract 37 from 180 to find the leftover amount.

180-37=43

So, in conclusion:

A= 37 degrees

C= 43 degrees

Hoped this helped! :D

xxTIMURxx [149]

Answer:

Explained below.

Step-by-step explanation:

A standard abacus is a traditional method used to perform basic mathematical calculations, such as addition, subtraction, multiplication and division.

There are 5 rods on a standard abacus.

The shape of the abacus has a series of vertical rods on which a number of beads are placed.

Each bead on a particular rod is considered as 1 unit, i.e. if there are three beads on a rod, the value of that rod is 3.

The last rod on an abacus is for the unit's place, the second last rod is for the ten's place, the third last rod is for the hundredth's place, the fourth last rod is for the thousandth's place and the fifth rod is for the ten thousandth's place.
