Answer:
960 i think
Step-by-step explanation:
800 x 0.04 = 32
32 x 5 = 160
800 + 160 = 960
hope i helped
I believe she will have 8 rolls of toilet paper left after one year.
She started with 36, then gave away 4, so then she would have 32 left for herself, then she used 2 every month so if you deduct 2 rolls every month for 12 months she would use 24 in one year. So 32-24 is 8.
Answer:
56 grams.
Step-by-step explanation:
In the sixth vertical string on the right, we have two cherries.
Since it is balanced, each of the other 3 strings(3rd, 4th and 5th) on the right will weigh two cherries.
Therefore:
Right Hand Side(3rd,4th,5th and 6th string) = 4 X 2 Cherries=8 Cherries
The fist string carries a weight of 2 Mushrooms
Therefore the second string will also weight Two Mushrooms.
Left Hand Side(1st and 2nd string)=2 X 2 Mushrooms =4 Mushrooms
Therefore:
Right Hand Side=Left Hand Side
8 Cherries=4 Mushrooms
One Cherry is 7 grams
Therefore:
4 Mushrooms =7 X 8 =56 Grams
The total weight of the left hand side is 56 grams. Therefore, the exotic fruit weighs 56 grams.
There are standard formulas for this type of problem. However, it can also be solved by a combination of simple steps.
First, the shortest distance from the point (3,5) to the line y = x +4 (line1) will be along a straight line perpendicular to line1. Give the perpendicular line the name line2. Since the slope of line1 is 1, the slope of line2 will be -1.
Second, since line2 must go through (3,5) and also have a slope of -1, the point slope form can be used for line2:
y - 5 = (-1) (x -3)
So the equation of line2 is y = -x +8.
Third, the point of intersection of line1 and line2 can be found by solving the set of equations:
y = x +4
y = -x + 8
The solution of this set of two equations is x = 2, y = 6 i.e. the point (2,6) .
Fourth, the distance formula can be used to find the distance between (3,5) and (2,6)
d = sqrt( (3-2)2 + (5-6)2 ) = sqrt(2)
This is the desired distance.
Answer:
x=-3 y=17 (-3;17)
Step-by-step explanation:
-3x+8-y=0
-5x+2-y=0
-2x-6=0
So: x=-3
While....by substituting: y=17
