To determine the density of grains, a student uses a 50ml beaker graded by 5ml increments and a scale with 1g absolute uncertain

labwork [276]

Answer:

The mass of the grains = 120 ± 1 g

Step-by-step explanation:

we are given the following:

Total mass of container + grains = 185 grams

Mass of container = 65 grams

Therefore, mass of grains is calculated as follows:

Mass of grains = ( Mass of container + grains) - mass of container

= 185 - 65 = 120 grams.

since the scale has an absolute uncertainty of 1 g, the mass of the grains is written as 120 ± 1 g

~Hello There!~

$\frac{m}{s} =\frac{2}{5}$

Rearrange for s

$s = \frac{5m}{2}$

After 8 years, the new equation would be:

$\frac{m+8}{s+8} =\frac{1}{2}$

Cross multiply

$2m+16 = s+8$

Subtract 8

$2m+8=s$

Substitute old equation

$2m+8 = \frac{5m}{2}$

Solve to get m as 16.

s = 40.

Their current ages are 16 and 40 and the different is 24 years. Therefore, Caitlin is correct.

Hope This Helps You!

Good Luck :)

Have A Great Day ^_^

Preform the subtraction: (5x^2 -3xy +10y^2) - (12x^2 +11xz- 7z^2)

Rzqust [24]

we are given

$(5x^2 -3xy +10y^2) - (12x^2+11xz-7z^2)$

we have to subtract

step-1: Distribute negative sign

$=5x^2 -3xy +10y^2-12x^2-11xz+7z^2$

step-2:Combine like terms

$=5x^2 -12x^2-3xy -11xz+10y^2+7z^2$

$=-7x^2-3xy -11xz+10y^2+7z^2$

we get

$=-7x^2-3xy -11xz+10y^2+7z^2$ ............Answer
