Answer:8
Step-by-step explanation:
The equation for a triangle is base times height times 1/2 so if 8 times 6 gives you 48 once you divide it by two it gives you 24
Answer:
cement by 5 Kg
Step-by-step explanation:
add the parts of the ratio, 5 + 4 + 1 = 10 parts
Divide the quantity of concrete by 10 to find the value of one part of the ratio.
110Kg ÷ 10 = 11Kg ← value of 1 part of ratio , thus
5 parts = 5 × 11Kg = 55Kg ← cement required
4 parts = 4 × 11Kg = 44Kg ← sand required
1 part = 11Kg ← gravel required
He requires 55Kg of concrete but only has 50Kg.
He requires 44Kg of sand and has 55Kg
He requires 11Kg of gravel and has 15Kg
Thus he is 5Kg short of cement.
z score = (1300-1700)/75
z score = -400/75 = -5.33
Set the equation to look like
20/100 = x/25
Then multiply to get
500 = 100x
500/100 = x
5 = x
Therefore James spent 5 dollars initially on ingredients.
Answer:
175 pages
Step-by-step explanation:
Let's call 'd' the number of days before the deadline, and 'n' the total number of pages of the book.
We have the following equations:
(1) 
--> if we multiply the number of pages per day (25) times the number of days (d), we get the total number of pages of the book (n)
(2) 
--> he reads 8 pages more per day (so, 25+8), for a number of days equal to (d-2) (d is the deadline), and he reads a total of n-10 pages (because only 10 are left)
We can substitute (1) into (2) and we find:
So, the deadline is 7 days, and from eq.(1) we find the number of pages in the book:
