The total number of pupils is

7 + 2 + 5 + 3 + 4 + 6 + 8 + 6 = 41

Number who don’t study chemistry

7 + 2 + 5 + 6 = 20

Probability they don’t study chemistry is 20/41

Answer:

432

Step-by-step explanation:

Volume of cuboid:

12 x 4.5 x 5.5 = 297

volume of traingular prism:

(12x5)/2 x 4.5 =135

add them together:

135+297 =432

hope this helps!

A vertex of square is at(1,1) and its two parallel sides are y=x and y=x+1. find the equation of the remaining sides.Show your w
belka [17]

Answer:

\displaystyle y  =   - x  +  2

y =  - x  +1

Step-by-step explanation:

we are given a vertex of a square i.e <u>(</u><u>1</u><u>,</u><u>1</u><u>)</u>

and the equations of the two parallel sides

notice that, the given vertex coordinates satisfy one of the parallel side i.e <u>y=</u><u>x </u>which means that (1,1) points lie on one of Parallel sides

remember that,

every angles of a square is <u>9</u><u>0</u><u>°</u><u> </u>

therefore,

we need to figure out the remaining <u>Perpendicular</u><u> </u><u>line </u><u> </u>of the given Parallel sides so

let's figure out the perpendicular line of y=x line

recall that,

Parallel lines have the same slope thus

\displaystyle  m_{  \rm perpedicular} =  - 1

since we are given a vertex the equation of the perpendicular line should be

\displaystyle y - 1 =  - 1(x - 1)

distribute:

\displaystyle y - 1 =  - x  +  1

add 1 to both sides:

\displaystyle y  =   - x  +  2

to figure out the second perpendicular line we can consider the coordinates (0.5,0.5) of y=x equation

so the slope of the perpendicular line is -1

and the equation:

y - 0.5 =  - 1(x - 0.5)

distribute:

y - 0.5 =  - x  +0 .5

add 0.5 to both sides:

y =  - x  +1

and we are done!

Solve for y:<br> -1/2=3/8y y=?<br> 10 points btw!<br> Also look at the picture
mihalych1998 [28]

Answer:-8/6=y

Step-by-step explanation:

You have to do KCF which means keep the number on the left or right left in this case, change the mark to a multiplication symbol, and then flip the other fraction which means 3/8 will be 8/3 and if you are looking for a mixed fraction asnwer would be -1 1/3 pls mark as brainliest if right
