At my favorite drugstore, comic books used to cost 10¢ .
(It wasn't yesterday, or even last week. In fact, the drugstore
was burned to the ground during the riots in 1964, and never
rebuilt. But I digress.)
Normally, my parents only let me buy one comic book at a time.
But before I left for summer camp, I could empty my little piggy
and spend it ALL on comic books, all at the same time ! That
was as much fun as the whole 2 weeks at camp !
I emptied my little pig. I had 67¢ in there. I headed for the
drugstore. For the whole rest of the afternoon, I stood at the
magazine rack, carefully deciding on my selections.
How many comic books did I buy ?
What was the remainder ? (How much money did I have left ?)
Answer:
Step-by-step explanation:
Micah is 48 years old.
E.
K = 6
R = ( 6 x 4 ) = 24
M = (( 6 x 4 ) x 2 )) = 48
Answer:
Perimeter of Δ XYZ = 24.13
Step-by-step explanation:
In Δ XYZ is a right triangle because the XYZL is a square. Therefore the hypotenuse = 10; Looking at the 43° angle, XY is the side that is opposite the 43° angle and the YZ is the side that is adjacent to the 43°.
Using the trig ratios:
XY = opposite/ hypotenuse which is Sin 43°
Sin 43° = XY/ 10
10(Sin 43°) = XY
6.82 = XY
YZ = adjacent/hypotenuse which is Cos 43°
Cos 43° = YZ/10
10(cos 43°) = YZ
7.31 = YZ
Now the Perimeter = XY + YZ + XZ
Perimeter = 6.82 + 7.31 + 10
Perimeter = 24.13
Answer:
first triangle (to left) b=8, second one c=17
Step-by-step explanation:
for the first triangle (one to the left) the hypotenuse is 9, so let's use the pythagorean formula.
A^2 + B^2 = C^2
^ ^ ^
^ ^ Hypotenuse
^ second side
first side
Substitute:
5^2 + b^2 = 9^2
SImplify:
25+b^2 = 81
Reduce:
b^2 = 64
Simplify:
b=8
In the second triangle, we are given 2 sides.
Let's do the same thing we did in the first one.
Givens:
A = 8
B = 15
Find:
C
Substitute:
8^2 + 15^2 = c^2
Simplify
64 + 225 = c^2
Reduce:
289 = c^2
Let's now square root both sides
square root of 289 is 17
so we are left with this:
c=17
Phew, you did it!
Hope this helped :))
Using PEMDAS
P = 1x1+9x(0.01)+1x(0.001)
E = no change
M = 1+0.09+0.001
D = no change
A = 1.091
S = no change
final answer is 1.091
