Step-by-step explanation:
By Pythagoras' Theorem, z^2 + (2.7)^2 = (4.2)^2.
This means that z^2 = (4.2)^2 - (2.7)^2 = 10.35.
So z = 3.2 (1 d.p.)
Answer: 233.7
Step-by-step explanation:
So you have to break it down
Each workout he jogged and rode his bike
Everyday he jogged for for 45 minutes
He totaled 360 minutes for the week.
There are seven days in a week so divide the 360 by the 7 51 3/7 minutes everyday
Subtract 45 from it 6 3/7
So the answer is he jogged 6 minutes and around 26 seconds everyday
(Concert the 3/7 to seconds by my tip lying it by 60)
Part A: 0.7(x)
Part B: 8.96/0.7 ---> (You can solve this by yourself)
For getting the answer, you can assume the regular price of the book is x. Then, the sale price would be x-0.3x, which is 0.7x
For part B, the price is 0.7 of the original. Dividing the number by 0.7 gets you the original price
So, the equation would be -
1.50x + 10 = 40
and you have to find the value of x
1.50(?) +10 = 40
The value of x would be 20
1.50 x 20 = 30 +10 = 40
Your answer would be that
