For 6, to get the sales tax, you multiply the price of the videogame (52.99 in this case) and multiply it by 0.07 to get 3.7903 = around 3.79 dollars. For the total cost, we add the sales tax to the regular cost to get 52.99+3.79=56.78 dollars
For 7, since we need 3 (2+2/3) cuts of wood, we simply multiply (2+2/3) by 3 to get 6+6/3=6+2=8 feet. To find out how much is left, we subtract 8 from 10 to get 10-8=2 feet left
Answer:
Thus, 3/2 in, or 1.5 in, represents 1 mile.
Step-by-step explanation:
"3 quarter inches to the half mile" can be expressed as "3/4 inch to 1/2 mile."
Write and solve an equation of ratios to obtain the unit rate in inches/mi:
3/4 in x
---------- = ---------
1/2 mi 1 mi
Cross multiplying, we get 3/4 in-mi = (1/2) mi*x.
Solve this for x by mult. both sides by 2:
6/4 in-mi = x mi
and then dividing both sides by mi:
(6/4) in-mi
--------------- = 3/2 in
mi
Thus, 3/2 in, or 1.5 in, represents 1 mile.
Answer:
The Answer is option A) .( 6 , -7 )
Answer:
They are both right-angled triangles.
Step-by-step explanation:
You have to first mess around with the first shape, ABCD, and split that into a rectangle and a right triangle. once you do that, it's pretty painstaking, but simple.
if you look at it you can tell that EFGH is just half the size, but the same ratios and everything.
So, you would just take every perimeter measurement from ABCD, and divide it by two and then sum them together.
2.5 + 1.5 + 4.0 + 2.0 = 10
