Answer 1

Answer: Triangular Prism:

$\sf~V=(1)/(2)*~l*~w*~h$

$\sf~V=(1)/(2)*7*3*3$

$\sf~V=3.5*3*3$

$\sf~V=10.5*3$

$\sf~V=31.5$

Break the Trapezoidal Prism into a rectangular prism with side measurements of 12, 18, and 6 and into a triangular prism with measurements of 6, 16, and 12.

Rectangular Prism:

$\sf~V=lwh$

$\sf~V=(12)(18)(6)$

Multiply all 3 numbers together:

$\sf~V=1296$

Now find the volume of the triangular prism:

$\sf~V=(1)/(2)lwh$

$\sf~V=(1)/(2)(6)(16)(12)$

Multiply all 4 numbers:

$\sf~V=576$

Add the two volumes together:

$\sf1296+576=1872$

Now we have to get rid of the area inside.

It's two rectangles both with lengths of 12 and widths of 6.

$\sf~A=lw$

$\sf~A=(12)(6)$

$\sf~A=72$

Multiply by 2 then subtract from the total volume we got:

$\sf~72*2 = 144$

Subtract it:

$\sf1872-144=1728$

Solve: 12 dogs decreased by 25% step by step pls.

Answers

decreased by 25%
find 25% of 12 and decrease 12 by it

percent means parts out of 100
25%=25/100=1/4
'of' means multiply
25% of 12=1/4 times 12=3

decrease 12 by 3
12-3=9

answer is 9

first turn 25% into a decimal so it's easier to work with, the decimal for 25% is 0.25

then multiply the number by the decimal

12x0.25=3

then subtract your answer (3) from your starting number

12-3=9

12 dogs decreased by 25% leaves you with 9 dogs left.

if you are increasing, divide instead of multiply

The Rogers family drove a total of 482 miles, starting onFriday and ending on Sunday. They drove 138 miles on Friday and 225 miles on
Saturday. How many miles did they drive on Sunday?

Answers

you add up 138+225 and you get 363 then you subtract 482-363 this is how you set it up:

4 8 2

- 3 6 3

------------

you have to borrow because 3 does not go into 2 so you change the 8 into a 7 then you 10 to 2 and you get 12 so this is what it looks like:

4 7 12

- 3 6 3

-------------------

so you then subtract 12-3=9 then 7-6=1 then 4-3=1

so this is what it looks like

4 7 12

--- 3 6 3

--------------------

1 1 9

so on Sunday they rode 119 miles
