1/3 of 12 = 2/3 of ?
Answers
Answer:
I think it's 6
Dhdneoemd
Answer:
6
Step-by-step explanation:
[tex]\frac{1}{3}[/tex] of 12 = [tex]\frac{12}{3}[/tex] = 4
let the number required be n , then
[tex]\frac{2}{3}[/tex] n = 4 ( multiply both sides by 3 to clear the fraction
2n = 12 ( divide both sides by 2 )
n = 6
Thus
[tex]\frac{1}{3}[/tex] of 12 = [tex]\frac{2}{3}[/tex] of 6
Marcus is a recent college graduate. He has $18,000 in student loans. He took out a loan to buy a car and owes $16,000. The car is now worth $14,000. He got his first paycheck and has $1400 in his checking account. What is Marcus' net worth? (Enter the positive or negative dollar amount only.)
Answers
Given :
Marcus is a recent college graduate. He has $18,000 in student loans. He took out a loan to buy a car and owes $16,000. The car is now worth $14,000. He got his first paycheck and has $1400 in his checking account.
To Find :
Marcus's net worth.
Solution :
We know, net worth is given by :
Net worth = $( Total amount owns - Total loan )
Net worth = $( 16000+1400) - ( 18000+14000)
Net worth = $(17400 - 32000)
Net worth = $-14600
Therefore, Marcus' net worth is $-14600 ( He is in a loan of $14600).
Hence, this is the required solution.
Chelsea and her friends are making small fruit baskets for their neighbors. They have 90 pears, 45 peaches, and 75 apples. What is the greatest number of baskets they can make if each basket has the same number of pears, the same number of peaches, and same number of apples, with no fruit leftover?
Answers
Answer:
15 baskets
Step-by-step explanation:
This question is a GCF question
The first step would be to find the factors of 45, 75 and 90
The factors of 45 are: 1, 3, 5, 9, 15, 45
The factors of 75 are: 1, 3, 5, 15, 25, 75
The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
The greatest common factor is 15.
Therefore, the greatest number of baskets they can make if each basket has the same number of pears, the same number of peaches, and same number of apples, with no fruit leftover is 15 baskets
A father's age is three times the sum
of the ages of his two children.After 5
years his age will be two times the sum
of their ages.Find the present age of the
father
Answers
After 5 years,
Father's age = (x + 5) years
Sum of ages of his children = (y + 10) years
From the given information, we have:
x = 3y ...(1)
and x + 5 = 2(y + 10)
x - 2y = 15 ...(2)
From (1) and (2), we have,
3y - 2y = 15 y = 15
x = 3y = 45
Father's age = 45 years

Amanda has four boards that are each 64 inches long. She needs to cut each board into multiple pieces that are each 12 45 inches long. How many pieces will she have after she cuts all four boards?
Answers
Answer:
You need to divide 64 by 12/45. Whenever you divide fractions you keep the first number as it is, change the sign to multiplication and write the reciprocal of the second fraction which is you have to flip the fraction. It is going to be 64 times 45/12. Which is 240/1 which is 240.
Step-by-step explanation:
Using simple algebra, it is found that Amanda will be able to cut 20 pieces of [tex]12\frac{4}{5}[/tex] inches length.
What is algebra?Algebra is the branch of mathematics that deals with mathematical operations and symbols operating on numbers, variables and expressions
Let Amanda cut total x pieces
Given that length of each piece =[tex]12\frac{4}{5}[/tex] inches = 64/5 inches
Total length cut for all the pieces can be found by multiplying the number of pieces with length of each piece
∴ Total length cut for x pieces = x × 64/5 = 64/5 x
Given that Amanda has 4 boards for cutting
Length of each board = 64 inches
Total length offered by 4 fours boards for cutting is calculated by multiplying length of each board by 4 .
Total length offered for cutting by 4 boards = 4 × 64 = 256 inches
Therefore,
Total length cut for x pieces = Total length offered for cutting by 4 boards
⇒ 64/5 x = 256
⇒ x = 256/(64/5) = (256×5)/64 = 4×5 = 20
Therefore, There will be 20 pieces cut from all four boards .

NUMBER 4!!!!!!! if m∠JKP= 67°, find m∠NKO
Answers
Answer:
Step-by-step explanation:
I have some sympathy for the way the questions have been set up and numbered.
The givens are that the two lines that look like they are perpendicular, are perpendicular.
<JKP = 67 Given
<PKL = 180 - 67 < PKL is supplementary to <JKP
<PKL = 113
<PKM = 113 - 90 = 23
Here's what you want to know. <NKO = PKM because they are vertically opposite angles.
Therefore NKO = 23 degrees.
JL is perpendicular to MN, then
m ∠NKO= 23°
Given :
JL is perpendicular to MN and the m∠JKP= 67°
we need to find out m∠NKO
we know that JL is perpendicular to MN. so, <JKN makes an right angle .
m ∠JKN = 90°
PO is a straight line . It makes an angle 180 degree
m ∠JKP +m ∠JKN +m ∠NKO =180
[tex]67+90+m<NKO=180\\m<NKO=180-90-67\\m<NKO=23[/tex]

Because |−8.46|>|5.31|, subtract |5.31| from |−8.46| and the sign is positive. HELP!! I am doing my hw for math and I don't get this question!!
Answers
Step-by-step explanation:
Sum of −8.46 and 5.31 means we need to add −8.46+5.31.
We know that,
|-8.46| > |5.31|
It means we subtract 8.46 - 5.31
At hundredth place, 6-1 = 5
At tenths place, 4-3 = 1
At ones place, 8-5 = 3
It would mean that, 8.46 - 5.31 = 3.15
8.46 has a negative sign. It means that the final answer will have negative sign i.e. −8.46+5.31 = -3.15
Hence, the correct option is (a) " Because |−8.46|>|5.31|, subtract |5.31| from |−8.46| and the sign is negative".

Answer:
y = -x - 4
Step-by-step explanation:
Looking at this graph straight off the bat we see the line is going downwards from left to right which is an indication of a negative slope. The slope is 1 considering the line's rise/run (2 units/2 units down on the graph). Thus, we know our slope is 2/2 = 1. Thus, our slope would appear as -(1)x or -x in the equation.
Next, we need to identify where the line crosses the y-axis to identify our y-axis point. Tracing the line, we see that it comes into contact with the vertical y-axis at -4 (4 units South on the y-axis).
Putting these both together we see the equation of the line is y = -x - 4.

To solve the figure. You need to split the shape up with the lines shown.
Let's solve the top triangle first.
The formula to find the area of a triangle is y = 1/2(b*h)
So the base is 2+2+6 which equals 10. And the height is 4.
So y = 1/2(4*10)
PEMDAS solve parentheses first.
y = 1/2(40)
y = [tex]20cm^{2}[/tex]
Now solve the bottom left one.
y = 1/2(2*2)
y = 1/2(4)
y = [tex]2cm^{2}[/tex]
Now the bottom right triangle.
y = 1/2(6*2)
y = 1/2(12)
y = [tex]6cm^{2}[/tex]
And to solve area of a square is
y = b*h
y = 2*2
y = [tex]4cm^{2}[/tex]
And add all of it up to get
y = [tex]20cm^{2}+2cm^{2} +6cm^{2} +4cm^{2} = 32cm^{2}[/tex]

Enzo and Beatrice are playing games at their local arcade incredibly ends wins five tickets from every game in the trees wins 11 tickets from every game when they stop playing games Enzo in the trees had won the same number of total tickets what is the minimum number of games that Enzo could have played
Answers
Answer:
22 games
Step-by-step explanation:
In order to find the minimum number of games that Enzo played we need to find the least common multiple of tickets where both Enzo and Beatrice are equal. To do this we simply find all the multiples of the number of games each could have played by the number of tickets per game until we find one in common.
5*1 = 5 11*1 = 11
5*2 = 10 11*2 = 22
5*3 = 15 11*3 = 33
5*4 = 20 11*4 = 44
5*5 = 25 11*5 = 55
... ...
... ...
... ...
5*22 = 110 11*10 = 110
Finally, we can see that the minimum amount of games that Enzo needs to play in order for both Enzo and Beatrice to have the same amount of tickets is 22 games.
