How the fuck did u get 7??? You didn't even say how

Easier to work out mentally. 52 x 3 = 156, add a 0 cos your multiplying by 10’s gives you 1560 which is 104 less than the total. 104 is 2 x 52 so it’s 32

Think of a circle area as a square where it's easier to associate sizes if you want something 4x the area. It's easier to visualize how much bigger the new square has to be. Assembling four 2x2 sqaures to make a square would make it 4x4

Like this if you are long out of school and did this successfully before he started working it without looking anything up! Let's be proud of ourselves!

k² = 4, k¹ = 2 (ratios with the exponent being the number of dimensions). Same with a sphere that has a volume 27 times as big as another one with a radius of 5 cm. The radius is 3*5cm Hypergeometry aside, you can also do this between volumes and and areas. A cube whose faces have an area 25 times greater than the other cube's, then the radius is 5 times greater and its volume will be 125 times greater

4.0003594946 isn't an option.

Just took my PiCat and then my verification test and I passed with a 68 thanks to grammar hero!

याच्या आईची गांड... शेट्याऐवढ गणित आणि परवता एवढं explination द्यालय😂😂😂

Thank You 🙏

I passed my Asvab grammar hero on my last try. I went from 17,23,53. Thank Youuuuu ❤

D, 49 The difference between 4 and 9 is 5 The difference between 9 and 16 is 7 The difference between 16 and 25 is 9 The difference between 25 and 36 is 11 so the next number in the pattern would be 13 and 13 + 36 = 49

Thanks

I am getting ready for my OAR, hopefully these are good practice questions for the OAR as well

15/4 = 3.75 X 100 = 375

This is what tik tok needs

A) 4” is the correct answer.

In a multiple choice question, you can eliminate all but one with almost no work. 52 ends in 2, 1664 ends in 4 so the last digit in the answer has to end in 2 or 7.

D

any answer that is over half.

Would I be wrong if I just looked at the question and assumed by it saying twice as large that it would just be 4?

4... a function of the constant pi coupled with the square of the radius. 2 squared is 4, 4 squared is 16.

2², 3², 4², 5², 6² 7²=49

My solution for the negatives one (like this one) is whatever the number is, is how many zeros there will be in total 0.000112

Wait...... what happend to all the malarkey adding to subtract then multiply to divide common core crap? Has society gone back to the basics..? About time.

My brain works differently. I think to myself: "250 is slightly more than half of 450. Which of these fractions looks slightly more than half? Oh, 5/9, that must be the answer." 😂

Hope you are doing well Grammar Hero, I am someone that originally scored a 40 on my practice PICAT my Marine Recruiter sent me and is having to go take the actual PICAT here very soon. my question is, as someone that is trying to score a 60 + to do cyber security things in the Marines, where do you recommend I start at as someone who graduated High School in 2020 and who has always struggled with math?

#20 threw me off due to wording... rest were easy imo by logic there's only upstream or downstream. across the river is something else so the wording threw me off but thinking about each term as an independent variable makes sense

I usually give up with the train problems but when I took the practice at the recruiters office I saw it, surprisingly I got it right cause it didn’t include fractions but I still struggle to understand it.

49

Itsa 48

Thank you

Hi Grammar Hero, do I always move the negative symbol to the numerator if the fraction has a negative symbol next to it? Each video has been helping me so far, thank you.

Thank you.

This one was on my practice 💀

How does it go from 3 and 1/4 to 3 and 4/4 at 13:26? Thanks

i studied economics in college, got a whole degree based around math. . . and i didn’t even think to square the numbers😂

Or....you could notice the pattern lol +5,+7, +9, +11. Add 13 to 36=49

A

I'm sure there is a math answer for how I got this but my pattern was adding the next odd number lmao, 4+5, 9+7, 16+9, 25+11, 36+13. Why does it work!

@grammarhero how did you get the 5 from 25?
