Answer:

  $5.68

Step-by-step explanation:

142% of the current price of $4 per gallon is found by multiplying these numbers:

  142% × $4.00/gal = $5.68/gal

_____

Of course, you know that 142% = 142/100 = 1.42. The numbers get multiplied and the units ($/gal) get applied to the result.

Multiplication by 4 is easily done mentally by doubling twice:

  4×1.42 = 2×(2×1.42) = 2×2.84 = 5.68

Answer:

Step-by-step explanation:

142% is about 140%. Using the distributive property, 140%($4) = 100%($4) + 40%($4) = $4 + $1.60. So, the price of gas is expected to be about $5.60 per gallon.

mojhsa [17]
The decrease is 35c

Q= X/100 of $1.37 = 0.35

1.37x/100 = 0.35

1.37x = 35 then divide each side by 1.37

Result is 25.5474453 percent, round up to nearest tenth.

7500 portions of strawberries have been ordered for the tournament, but because of bad weather only 5 /6 of the order has been d
Sladkaya [172]
The constant of proportionality is 1,250 the 5/6 is 6,250. You have to now find out the 10% by multiplying it which = 625. 625 is not the amount that they can sell that is the amount that they gave to the players and staff. So now you have to subtract 625 from 6,250 which would give you 5,625 strawberry's.

Let x and y be any numbers at all with x ≤ y. Show that the number of integers between x and y is [y] - [x] +1.That is show that
ddd [48]

Answer:

the explanation is given below.

Step-by-step explanation:

  • Here what is applied is assumption of range of values of number from say 1 - 100
  • In total, i stopped at 100 on the dot.

from this, the lowest number is 1 and the highest number is 100

  • hence the range of the numbers = Difference between Highest and Lowest
  • range = 100 - 1 = 99, the 99 gotten as the range is indicative that a number has been missing.

  • In order to make up the 100, an integer is added to the difference = 99, i.e 99 is added to 1 to make up the 100.

  • Furthermore, if 0 is exclusively out when numbers are counted up 100 with 0 inclusive, in such case, the first and last number are excluded from the counting. as such the integers will be {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20.........., 99} since both 0 and 100 are not included.

  • Here, if we try to get the range = highest - lowest = 99 - 1 = 98, it implies that to make up the 99, an integer is added to the result of the difference = 98+1 = 99

  • As such, the number of integers between two numbers is the difference between the highest and the lowest number plus 1 i.e highest - lowest + 1 = y - x +1 = (the floor of y) - ( the ceiling of x) + 1
