Answer:
$28 3/4
Step-by-step explanation:
One way of doing this is to sum up the increases and the decreases of the price, separately. One then adds the increases to the beginning price ($33 3/8) and subtracts the decreases from this sum:
$33 3/8 + ($4 1/4) - ($8 7/8), where $33 3/8 is the beginning price,
$4 1/4 is the sum of the price increases
for the day, and $8 7/8 is the sum of the
price decreases for the day.
Then we have:
$33 3/8 + $4 2/8 - $ 8 7/8
Here we need sum up the beginning price and the price increase for the day first:
$33 3/8 + $4 2/8 = $37 5/8
We cannot subtract $8 7/8 from $37 5/8 without borrowing. Borrowing, we get:
$36 13/8
and from this we subtract $8 7/8:
$36 13/8
- $ 8 7/8
----------------
$28 6/8
This can be reduced to $28 3/4. This was the closing price.
Sin 45 = sin 45
sin 135 = sin (180 - 45) = sin 45
sin(225) = -sin(180 + 45) = -sin 45
sin 315 = -sin(360 - 45) = -sin 45
cos 224.5 = -cos(180 + 44.5) = -cos 44.5
cos 658 = cos(658 - 360) = cos 298 = cos(360 - 62) = cos 62
cos 145.7 = -cos (180 - 34.3) = -cos 34.3
sin (-201) = sin (360 - 201) = sin(159) = sin (180 - 159) = sin 21
To find the width of the scale drawing of the toddler room, you can set up a proportion/ratio.
2.5 m/4 m= 5 cm/x cm
To get from 2.5 to 5, you multiplied by 2, so you will do the same thing to 4 to find the missing scale width.
4 x 2 = 8 cm
The width of the scale drawing is 8 cm.
This called the distributive property.
The distributive property states that a(b + c) = ab + ac
Answer:
<h2>w=6</h2>
Step-by-step explanation:
7w-6=3w+18 I expanded the bracket
+6 on both sides
7w=3w+24
-3w on both sides
4w=24
divide both sides by 4
w=6
