Answer:
46656
Step-by-step explanation:
6x6x6x6x6x6x6 can be written in its index form as 6⁷
6x = 6⁷
6x = 279936
Applying change of subject formula, divide both sides of the equation by 6
6x/6 = 279936/6
x = 46656
Answer:
EF = 6.6
Step-by-step explanation:
Since ABCD is similar to EFGH, then EH is similar to AD. So, we can solve by first dividing 12 by 2 (EH by AD). The quotient of this is 6. This tells us that quadrilateral EFGH is 6 times larger than quadrilateral ABCD, since they are similar. So, with this and the measurement of AB (which is similar to EF), we can now solve for EF. We simply multiply 1.1 (the measurement of AB) by 6 (how many times larger EFGH is compared to ABCD). The product of this is 6.6, our final answer.
Answer:
B
Step-by-step explanation:
X=Amount of hours you drive (70mph)
Y= Amoumt of hours your friend drives (75mph)
X+Y has to be equal to or less than 10 (X+Y=or<10)
You want to drive 500 miles or more in 10 hours or less at an average speed of 70mph for you and 75mph for your friend.(70X+75Y=or<500)
So overall....
X+Y=or<10
70X+75Y=or>500
(Both X and Y can be equal to zero or greater)
