Answer:
(0.88, 0,65)
Step-by-step explanation:
what do we have to do ? I assume we need to find the crossing point between the 2 lines.
when looking at the graphic, we can already rule out the first, third and fourth option.
none of the coordinates of that point is larger than 1 in any direction or smaller than 0.5.
so, just by looking at things I immediately "bet" on answer option 2 (0.88, 0.65).
but let's check.
y = -2x/5 + 1
y = 3x - 2
for the crossing point both functions must produce the same functional value.
=>
-2x/5 + 1 = 3x - 2
-2x/5 + 5/5 = 15x/5 - 10/5
-2x + 5 = 15x - 10
15 = 17x
x = 15/17 = 0.88...
y = 3×0.88... -2 = 0.65...
hurray, our original observation and "suspicion" is confirmed.
Answer:
He earn $40
Step-by-step explanation:
To solve this problem, we first have to calculate how much it spends to make each pie
cups of fruit = 5
5 * $0.75 = $3.75
This means that per pie he spends $ 3.75 on cups of fruit and $ 2.50 on pie crust
If we add them together we will get how much he spends for each pie
$3.75 + $2.50 = $6.25
Now to the price that the pie sells we subtract this value to know how much you earn for each pie
$10.25 - $6.25 = $4
if he sold 10 pies we multiply this number by 10 and we will get his total profit
$4 * 10 = $40
He earn $40
I really hope that helps cause I went all out and best of wishes!!
Answer:
99.
Step-by-step explanation:
A palindrome number is one that can be read in the same way both from the front and from the back. A clear example is the number 242, which starts and ends in the same way from the front or back.
Between 10 and 100, there are 9 palindromes, from 11 to 99. In turn, between 100 and 200, 200 and 300 and so on, each hundred has within it 10 palindromes (101, 111, 121, 131, 141 , 151, 161, 171, 181 and 191, for example).
Therefore, considering the 9 hundreds between 100 and 1000, there will be 90 palindromes, which added to the 9 between 10 and 100 give a total of 99 palindromes.
