Can you give a reason why a calculator shows 2/3 equal to 0.666666667
Answers
The division of 2 by 3 will give an answer which does not terminate so the calculator rounds the answer.
Given division problem is 2 by 3.
Here it clearly cannot be divided evenly.
The quotient is 0.6666....
We know about the rounding of numbers.
When the next number is greater than 5, the preceding number will add 1.
Here each number is 6, which is greater than 5.
So any number can be written as 7 and then stop the answer.
So this can be written as :
0.7, 0.67, 0.667,...
Hence the calculator shows 7 after certain digits.

given that one root is twice the other for the quadratic equation px-3x^2=24 . Find the values of p
Answers
3*-24=-72, so 2 numbers have to add to 72 but multiply to a number p. If a number is y and the other is 2y, that means that y*2y=-72 and 2y^2=72. Therefore, y^2=36 by dividing both sides by 2 and y is either 6 or -6. If y is 6, then 2y is 12 and 6+12=18=p
If y is -6, then 2y=-12 and -6-12=-18=p

betty's container of cranberry juice holds 200 milliliters. Herbert's container holds 7/8 as much juice. how many milliliters of cranberry juice do the two containers holds?
Answers
1. B= 200 (Betty's container hold 200 milli liters)
2. H= 7/8 B (Herbert's container hold 7/8 as much juice)
If you put the 1st equation into the 2nd, you will get:
H=7/8 (200)= 175
Then the two containers will hold
H+B= 200 + 175= 375milli liters
The ratio of the angle measures of the acute angles in a right angle is 2:3. Find the measures of the acute angles.
Answers
2 acute angles in right triangle, sum = 90
ration 2:3
so 2+3 = 5
90 / 5 = 18
2 x 18 = 36
3 x 18 = 54
so 2:3 = 36:54
answer
the measures of the acute angles are 36 and 54

a tree branch has 5 buds. each day 2 more buds sprout . how many buds are on the tree branch after 5 days. make a t chart
Answers
2 days = 4 buds
3 days = 6 buds
4 days = 8 buds
5 days = 10 buds
Answer:
Total number of buds on the tree branch after 5 days is:
15
Step-by-step explanation:
A tree branch has 5 buds.
Each day 2 more buds sprout.
i.e. After Day 1 number of buds=5+2=7
After Day 2 number of buds=7+2=9
After Day 3 number of buds=9+2=11
After Day 4 number of buds=11+2=13
After Day 5 number of buds=13+2=15
Hence, Total number of buds on the tree branch after 5 days is:

The quotient of two consecutive positive integers is 1.02. What is the sum of these two integers?
Answers
We are told:
x = y + 1 (consecutive integers) EQN (1)
and
[tex] \frac{x}{y} =1.02[/tex] EQN (2)
Solving this system of equations gives
[tex] \frac{y+1}{y} = 1.02[/tex]
Solving yields
y = 50 and x = 51
If quotient of two consecutive positive integers is 1.02 then the sum of the two integers is 101.
What is Number system?A number system is defined as a system of writing to express numbers.
Let x be the smaller of the two consecutive positive integers. Then, the next consecutive integer is x + 1.
According to the problem, the quotient of these two consecutive integers is 1.02. In other words:
(x + 1) / x = 1.02
Multiplying both sides by x, we get:
x + 1 = 1.02x
Subtracting x from both sides, we get:
1 = 0.02x
Dividing both sides by 0.02, we get:
x = 50
Therefore, the two consecutive positive integers are 50 and 51, and their sum is:
50 + 51 = 101
Therefore, if quotient of two consecutive positive integers is 1.02 then the sum of the two integers is 101.

Using the distributive property, which expression is equivalent to 5(32)? 5(3+2) 32(5+2) 5*30 + 2*30 5(30+2)
Answers
5(32)
=160
5(30+2)
(Using distributive property)
150+10
=160
The given expression 5(32) using the distributive property will be 5(30+2). The correct option is E.
What is Distributive property?The distributive property of multiplication is that when two numbers are added such as (a+b) and multiplied by a third number such as x, then the result will be the sum of the multiplication of the third number with the first number (xa) and the third number with the second number (xb).
x(a+b) = xa + xb,
The given expression using the distributive property can be written as,
5(32) = 5(30 + 2)
Hence, the given expression 5(32) using the distributive property will be 5(30+2).
