Step-by-step explanation:
The formula that relates the length of a ladder, L, that leans against a wall with distance d from the base of the wall and the height h that the ladder reaches up the wall is L = StartRoot d squared + h squared EndRoot. What height on the wall will a 15-foot ladder reach if it is placed 3.5 feet from the base of a wall?
L = √d² + h²
Answer:
58100
Step-by-step explanation:
The way I see it is move the decimal point over to the right (or left depending on whether its negative or not) however many units the exponent says. After it moves over the number, add the zeroes for the remaining amount of spaces until you have moved it over the correct amount. I'm not sure if that made any sense, but I know the answer is correct.
Answer:
B
Step-by-step explanation:
This is pretty easy because you'll only have one variable.
First draw a box and label your width as 12 cm, your length as 2w (because it is twice the length of the width), and your height as 2w+10(beacuse it twice the width{2w} plus 10cm)
Then, substitute 'w' for the widths measurement(12)
So, 2w becomes 2 x 12 or 24cm and 2w+10 becomes (2 x 12) +10 or 24+10 which is 34 cm
then just simply use the volume formula of a box which is V=lwh or length x width x height, so its 12 x 24 x 34 which equals 9,792 cm^3
Answer:
For the first one the answer is:
<K = 31°
Sorry I don't know the second one.
