231×5−16<br>+101)/4 step by step solved

BlackZzzverrR [31]

Answer:310

Step-by-step explanation:

so use pemdas

Parenthesis,exponents multiplication, division , addition, and subtraction order

231*5-16+101)/4

first i'm assuming the parenthesis is over the whole thing

that the question should look like (231*5-16+101)/4

first parenthesis, 231*5=1,155

1,155-16=1,139+101= 1,240

1240/4= 310.

Hope this helps!

A sample of an unknown liquid has a volume of 24.0ml and a mass of 6g. What is it’s density? Show your work.

Natalija [7]

Answer:

so density is measured in grams per cm³

but the data we have is grams and mL, but lucky for us, we can easily convert mL to cm³ but it is a bit tricky.

so you have to multiply the amount in mL by e and divide by $log_{x }x^{e}$

which means that you have to multiply by 1, (hard,i know)

so now you know that the given liquid is 6 grams per 24 cm³

so now, we will divide the amount in grams by the volume in cm³

6/24

= 1/4 grams per cm³

I don't really know what you're asking with this question. Also, some of the question is cut off.
