Choose the fraction that is equal to 0.245 A. 49/10 B. 245/999 C. 245/900 D. 245/1000
Final answer:
The correct fraction equal to the decimal 0.245 is 245/1000, which is option D in the given choices. This is determined by looking at the place value of the decimal and converting it into a fraction by placing the number over the corresponding power of ten.
Explanation:
To choose the fraction equal to 0.245, we need to convert the decimal to a fraction. To do this, we look at the place value of the farthest digit to the right in the decimal, which is in the thousandths place, since 0.245 can be written as 245 thousandths. Thus, the fraction is 245 over 1000, which simplifies to 245/1000.
Looking at the given options, we can see that option D is 245/1000, which is equivalent to the decimal 0.245. Therefore, the correct answer is D. Additionally, if we were to divide 1.9436 by 1000 as in your provided example for converting decimals and fractions, we would have 0.0019436. Similarly, to change the decimal 0.0479 to a number from 1 to 10, we move the decimal point two places to the right, obtaining 4.79, which shows an understanding of decimal and fraction conversion.
Graph y = 3/4 + 2.??? Idk what this is
Answer:
This equation is for a linear graph.
y = mx + b, where m is the slope and b is the y-intercept. To graph this, plot a point at (0, 2), as that is your y-intercept.
As for the slope, always remember [tex]\frac{rise}{run\\}[/tex]. What this means is you first count up before counting horizontally for the slope. Your slope is 3/4, so from your y-intercept, count three numbers up, and four to the right (since the slope is positive). This second point should be at (4, 5)

Peter & Alex share a lottery win of £4450 in the ratio 4 : 1. Peter then shares his part between himself, his wife & their son in the ratio 1 : 6 : 3. How much more does his wife get over their son?
Answer:
His wife gets $1068 more than his son.
Step-by-step explanation:
Peter and Alex:
Peter gets [tex]\frac{4}{4+5} = \frac{4}{5}[/tex] of the total amount.
[tex]\frac{4*4450}{5} = 3560[/tex]
Peter gets $3560. He divides with his wife and son.
Peter gets [tex]\frac{1}{1+6+3} = \frac{1}{10}[/tex] of the amount, the wife gets [tex]\frac{6}{1+6+3} = \frac{6}{10}[/tex] and the son gets [tex]\frac{3}{1+6+3} = \frac{3}{10}[/tex]
Wife:
[tex]\frac{6*3560}{10} = 2136[/tex]
His wife gets $2136
Son:
[tex]\frac{3*3560}{10} = 1068[/tex]
How much more does his wife get over their son?
2136 - 1068 = 1068
His wife gets $1068 more than his son.

Slope from graph
Answer:
-1 is the slope
Step-by-step explanation:
to find the slope, you should find two different points on the line which is exactly on the grid. For example, (-2,0) and (-1,-1) is an ok choice. The formula for slope is y^2 - y^1 / x^2 - x^1 = slope
so it would look like -1-0 / -1-(-2)
then -1/1
which is -1

a check would be a decrease to his checking account balance so 530.45 minus 16.50 would equal 513.95. 513.95 minus 95.68 equals 418.27. a deposit would be a increase to his balance. 418.27 plus 19.13 would equal 437.40.
You randomly choose one paper clip from a jar. In the jar there are 6 green, 3 white, 4 red, 2 blue, and 5 yellow paper clips.
Find the probability of the following:
Choosing a yellow paper clip
Answer:
You have a 25%, or 1/4 chance that you will choose a yellow paper clip.
Step-by-step explanation:
1) First, you want to find the total number of paper clips.
6 + 3 + 4 + 2 + 5 = 20 total paper clips
This is your denominator.
2) From the problem, we can understand that there are 5 yellow paper clips.
This is your numerator.
3) From the numerator and denominator we have from above, your fraction is 5/20.
4) This can be simplified into 1/4, which is 25%.
The probability of choosing a yellow paper clip is [tex]\frac{1}{4}[/tex].
What is probability?'Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.'
According to the given problem,

The daily gazzette has 25 companies that pay for advertising each month the newspaper wants to increase its advertisers by 5 each month what equation can be used to determine m the number of months it will take to double it
Answer: 25+5m =50
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The actual number of companies that pay for advertising each month (25) plus the product of the companies added per month (5) and the number of months (m) must be equal to the actual number of advertisers multiplied by 2 ( since they want to double it ).
Mathematically speaking:
25 +5m = 25 (2)
25+5m =50
Feel free to ask for more if needed or if you did not understand something.
Answer:
m=a/5
Step-by-step explanation:
From the statement, you have that the number of advertisers would be equal to the number of companies the daily gazzette has plus the 5 advertisers the newspaper wants to increase each month multiply for the number of months. From this, the expression would be:
2a=a+5m, where
a= number of advertisers
From this, we can isolate m:
5m=a
m=a/5
You can solve it to find the number of months it will take to double the advertisers:
m=25/5= 5
It will take 5 months as:
25+(5*5)= 25+25= 50

SAT verbal scores are normally
distributed with a mean of 450
and a standard deviation of 120.
Determine what percent of the
scores lie between 450 and 570.
Answer:
The percentage of the scores lying between 450 and 750 is 49.4%
Step-by-step explanation:
In this question, we are simply asked to calculate the percentage of the scores lying between a particular range.
The first thing to do here is to calculate the z score of both scores
Mathematically, z score = (x - mean)/SD
for score 450, we have ; z = (450-450)/120 = 0/120 = 0
For score 750, we have z = (750-450)/120 =
2.5
Now, we move on to calculate the probability before turning it into a percentage.
The supposed probability we are to calculate is as follows;
P(450 < x < 750) or P(0 < z < 2.5)
Using standard score table, P = 0.49379
The percentage is thus 49.4%

Happy Paws charges $20.00 plus $5.50 per hour to keep a dog during the day. Woof Watchers charges $9.00 plus $6.75 per hour. Complete the equation and solve it to find for how many hours the total cost of the services is equal. Use the variable h to represent the number of hours. The equation is
Answer:
8.8 hours
Step-by-step explanation:
Happy paws cost equation
5.50h + 20
Wood watchers cost equation
6.75h + 9
Make the two equations equal
5.50h+20 = 6.75h+ 9
Collect the co-efficient of both sides.
6.75h- 5.50h= 20-9
1.25h= 11
Divide both sides by the coefficient of h
1.25h/1.25= 11/1.25
h= 8.8
Answer:
8.8 hours
Equation :20+5.50h = 9 + 6.75 h
Step-by-step explanation:
Hi, to answer this question we have to write a Cost equation for each case:
For Happy Paws the cost will be equal to the fixed cost (20) plus the product of the cost per hour (5.50) and the number of hours (h).
Happy paws cost: 20+5.50 h
Same process for Woof Watchers:
Woof Watchers cost = 9 + 6.75 h
If both costs are equal:
Happy paws cost=Woof Watchers cost
So:
20+5.50h = 9 + 6.75 h
Solving for h
20-9 = 6.75h-5.50h
11 = 1.25h
11/ 1.25 =h
8.8 = h

b. What is the probability that you don’t roll a 2 or a 3, P (NOT a 2 or 3)? Explain your reasoning. (2 points possible)
1. In a game, if you roll a 2 or a 3 on a 6-sided number cube, you lose a turn. NOTE: This is just using one number cube.
Answer:
The probability that you don’t roll a 2 or a 3 = 2/3
Step-by-step explanation:
Formula for Probability = Number of Possible Outcomes / Number of events
We are told in the question that it is just a one number cube. This means that :
We have the Probability of rolling the 6 sided cube and obtaining, 1, 2, 3, 4, 5, and 6.
We are told in the question to find the probability of not rolling a 2 or 3.
Hence, this means
Probability( not a 2 or 3) = Probability( of a 1 or 4 or 5 or 6).
Therefore,
Probability (of rolling a 1) = 1/6
Probability (of rolling a 4) = 1/6
Probability (of rolling a 5) = 1/6
Probability (of rolling a 6) = 1/6
Therefore, Probability( not a 2 or 3) = Probability( of a 1 or 4 or 5 or 6) = P(1) + P(4) + P(5) + P(6)
= 1/6 +1/6 + 1/6 + 1/6
= 4/6
= 2/3.
Therefore, the probability that you did not roll a 2 or 3 ( i.e P( not 2 or 3)) = 2/3
