Levart [38]2 years ago

Answer:

Step 3

Step-by-step explanation:

Given

(5 - 2)^ 2 + 23 * 4

Required:

Determine the first step where she made mistake

Her Step 1:

(3)^ 2 + 23 * 4 --- This is correct because she solved the bracket first

Her Step 2:

9 + 23 * 4 --- This is correct because she solved 3^2 as 9

Her Step 3:

9 + 9 * 4 --- This is incorrect because 23 * 4 is not equivalent to 9 * 4

Hence, her first mistake is in step 3.

The correct expression would have been

9 + 92

Then

= 101

There are 60 students in Kinsley's grade. 3 of the students are enrolled in health. What
GREYUIT [131]
5% of the kids are in health. I got this from simplifying 3/60 which is 1/20

After that, i set up this equation: 1/20 times x/100

I would then divide 20 and 100 to get 5 and that’s basically what I did

PLS I NEED HELP I GIVE ALL POINTS I HAVE!! :( In 1984 the average American ate 55.7 pounds of chicken. This was 2.8 pounds more
olya-2409 [2.1K]

Answer: Production in 2007 reached more than. 91.5 billion pounds. ... billion pounds, with chicken production totaling 36.6 ... Average Annual Per Capita Consumption (in pounds). 0.0. 10.0 ... 1980 1982 1984 1986 1988 1990 1992 1994 1996 1998 2000 2002 2004 2006. Year ... half (55 percent) of all meat consumed are red meat.

simplfying to get 19.8928571429

then you mul·ti·ple equals 155.96

then you subtract and it gets you 52.9

then you add gets you 58.5.

This question is quite simple as long as you know how to do math you should ace all of your math classes..

Mathematics can get pretty complicated. Fortunately, not all math problems need to be inscrutable. Here are five current problems in the field of mathematics that anyone can understand, but nobody has been able to solve.

like...Pick any number. If that number is even, divide it by 2. If it's odd, multiply it by 3 and add 1. Now repeat the process with your new number. If you keep going, you'll eventually end up at 1. Every time.

Mathematicians have tried millions of numbers and they've never found a single one that didn't end up at 1 eventually. The thing is, they've never been able to prove that there isn't a special number out there that never leads to 1. It's possible that there's some really big number that goes to infinity instead, or maybe a number that gets stuck in a loop and never reaches 1. But no one has ever been able to prove that for certain.

So you're moving into your new apartment, and you're trying to bring your sofa. The problem is, the hallway turns and you have to fit your sofa around a corner. If it's a small sofa, that might not be a problem, but a really big sofa is sure to get stuck. If you're a mathematician, you ask yourself: What's the largest sofa you could possibly fit around the corner? It doesn't have to be a rectangular sofa either, it can be any shape.

This is the essence of the moving sofa problem. Here are the specifics: the whole problem is in two dimensions, the corner is a 90-degree angle, and the width of the corridor is 1. What is the largest two-dimensional area that can fit around the corner?

The largest area that can fit around a corner is called—I kid you not—the sofa constant. Nobody knows for sure how big it is, but we have some pretty big sofas that do work, so we know it has to be at least as big as them. We also have some sofas that don't work, so it has to be smaller than those. All together, we know the sofa constant has to be between 2.2195 and 2.8284.

AM I BEING TO MUCH OF A SMART ALECK, I'm sorry if i am LOL.

but if you need help with another question, you can ask me :)

Evaluate the following using<br> powers of ten rules.<br> 104)1.042
Alinara [238K]

Answer:

0.0001042

Step-by-step explanation:

Power of tens rule states that if the denominator of a fraction has the positive power of 10, decimal in the numerator will be shifted to the left by the same number of places as exponent.

10⁴) 1.042 = \frac{1.042}{10^4}

In the denominator of the given fraction, exponent of 10 = +4

So the decimal in numerator will be shifted left by 4 places.

\frac{1.042}{10^4}=0.0001042

Therefore, answer is 0.0001042
