Basically it's 2/3 for horses/acres so the answer would be 107.5 acres at least because 75/107.5 is 2/3.
Answer:
4 hrs
Step-by-step explanation:
half of Jim Rollers time is 1.5 hrs, and half of John Brushs time is 2.5 hrs. The two combined is 4 hrs. Therefore, the answer is four hours.
This is basically finding the average of two numbers, and you can use multiple different equations to find the same answer.
3/2 + 5/2 =4
(3+5)/2 =4
5-3=2, then 2/2=1, 5-1=4
Answer:
x = 18 cm
Step-by-step explanation:
(4x)^2 = 3(4x)(x+6)
16x^2=3(4x)(x+6)
divide both sides by 4x
4x = 3(x+6)
4x=3x+18
x = 18
Answer:
Girls = 16
Total students = 40
Step-by-step explanation:
40% of the students are girls, this means 60% of the students are boys.
To find the number of girls, setup a proportion using the percentages and actual number of students in the class. I am going to make the numerator the numbers that go with the girls and the denominator will be the numbers that go with the boys.
Also let's convert the percentages to decimals by moving the decimal two places left.
40% = 0.4 and 60% = 0.6

Now let's find the total number of students by adding the number of girls to the number of boys.
16 + 24 = 40
