123.51 divided by 2.3 show your work
Darya [45]

Answer:

53.7

Step-by-step explanation:

So first move the decimal in 2.3 by one to the left, making it 23. Now what you do to one thing you do to the other, now 123.51 becomes 1235.1. Now you have 1235.1 / 23. 23 goes into 1235; 53 times, leaving you with 16.1. Now we take 16.1 / 23. When you do that you get .7. Therefore your answer is 53.7

Hopefully this helped!

Find the exact perimeter of the triangle.<br>A.68 sqrt(x)<br>B.sqrt(68x)<br>C.5x+x sqrt(17)<br>D.68x
blondinia [14]
Hypotenuse²= (4x)²+ x²=16x²+x²=17x²

Hypotenuse=√(17x²)= x√17
To find perimeter, we need to add all sides
P=x+4x+ x√17 =5x+x√17 =x(5+√17)

Dont understand this question it confucing
Juliette [100K]
So, let's see, Amber made 3 penalty shots off 4, now, 3 out of 4 is 75% or 3/4.  So she's 75% of the time effective.

Lindsay has made 4 out of 6 penalty shots, 4/6 or 2/3, that's about 66% effectiveness.

Li has made 2 out of 3 penalty shots, that's 2/3, that's about the same 66% effectiveness.

so, which fraction is highest 3/4, or 2/3 or 2/3?  neverminding the percentages, let's multiply all by the LCD, let's see from 4, and 3, and 3, the LCD is 12.

so, let's multiply all of them by 12, to get rid of the denominator, to see which is highest.

\bf 12\cdot \cfrac{3}{4}\implies \boxed{9}\qquad \qquad 12\cdot \cfrac{2}{3}\implies \boxed{8}

notice, Amber has the higher effectiveness rate, to make it through in the penalty kick.
