which is greater 2/3 5/10 7/8 1/2 ?
Answer:
2/3 5/10 7/8 1/2
Step-by-step explanation:
hello :
2/3 =(2×8)/(3 ×8) = 16/24
5/10 = 1/2= (1×12)/(2 ×12)=12/24
7/8= (7×3)/(8 ×3)= 21/24
the greater is : 7/8
To determine which of the fractions 2/3, 5/10, 7/8, and 1/2 is the greatest, we must first convert the fractions to decimals. Once converted, 7/8 (0.875) is the highest decimal value, thereby making it the greatest fraction.
Explanation:To figure out which is greater among 2/3, 5/10, 7/8 and 1/2, we need to convert each of these fractions into decimals because it is easier to compare decimals than fractions.
So, 2/3 = 0.6667, 5/10 = 0.5, 7/8 = 0.875 and 1/2 = 0.5.
Comparing these decimals, it is clear that 7/8 (which equals to 0.875) is the greatest among the four.

there shop keepers go to a wholesaler to buy packets of mints. each shop small packets, medium packets and large packets of mints. Anne buys 600 packets of mints. 34% are small packets and 49% are large packets. Ben buys 400 packets of mints, 3/10 are small packets and 1/10 are large packets. Chas buys 210 small packets of mints so that number of small packets: number of medium packets = 3 : 4 work out the total number of medium packets of mints these shop keepers buy.
Answer:
medium 156+240+105=501
small 204 + 120=324
large 40+240 =280
Step-by-step explanation:
600 of what ever the percentage or the fraction to find each small and large also medium.
example = 600 x 34% =204
another example is 400 x 3/10 = 40
The total number of medium packets of mints bought by the three shopkeepers Anne, Ben and Chas is calculated to be 622, using ratios and percentages to determine the breakdown of packets bought.
Explanation:To solve this problem, we first find out the number of small, medium, and large packets each shopkeeper buys. For Anne, if 34% of 600 packets are small, she buys 0.34 * 600 = 204 small packets. Then, from the remaining packets 49% are large, which makes 0.49 * 600 = 294 large packets. The rest are medium packets, making 600 - 204 - 294 = 102 medium packets.
For Ben, 3/10 of his 400 packets are small, which makes 3/10 * 400 = 120 small packets. Also, 1/10 of his packets are large, hence 1/10 * 400 = 40 large packets. The rest, thus, are medium: 400 - 120 - 40 = 240 medium packets.
For Chas, if the ratio of small packets to medium packets is 3:4, meaning for every 3 small packets, there are 4 medium packets. She bought 210 small packets, thus for medium packets, using the ratio, it becomes 210 * (4/3) = 280 medium packets.
The total number of medium packets that these shopkeepers buy is thus: 102 + 240 + 280 = 622 medium packets.

Becca wants to edge her hexagonal garden with bricks. All sides are equal. The brickcosts $2 per foot. How much will it cost to buy tne edging she needs
Answer: $12a
Step-by-step explanation:
Cost of brick = $2 per foot
Cost of edging needed=?
Shape of garden = hexagonal= 6 sides and all sides are equal
The perimeter of a regular hexagon = 6×a
Where a = length of one of the sides , since the sides are equal.
Cost of edging = perimeter size (in feet) * cost per foot
Cost of edging = 6a * $2
Therefore, cost of edging = $12a
Where a = length of it's side in feet.
Answer: $144
Step-by-step explanation:
There are 12 feet on the hexagon so 12x2 is $24. there are also 6 sides on the hexagon so 6x24 is 144. (this is from a math textbook.)

A basketball with a diameter of 9.5 in. is placed in a cubic box with sides 15 in. long. How many cubic inches of packing foam are needed to fill the rest of the box? Round to the nearest tenth.
Answer:
2926.32 cubic inches
Step-by-step explanation:
Given the information:
A basketball with a diameter of 9.5 in=> its radius is: 9.5/2 = 4.75 in
As we know, the formula used to find the volume of the sphere is:
V =π [tex]\frac{4}{3} r^{3}[/tex]
=> the volume of the basketball is:
V = π [tex]\frac{4}{3} 4.75^{3}[/tex]
= 448.69 cubic inches
A cubic box with sides 15 inAs we know, the formula used to find the volume of a cube is:
V = [tex]a^{3}[/tex]
=> the volume of the box:
V = [tex]15^{3}[/tex] = 3375 cubic inches
Hence, The volume of foam there is needed to complete the box is the subtraction between the two volumes above:
= the volume of the box - the volume of the basketball
= 3375 - 448.69
= 2926.32 cubic inches

The new store will have a profit of $4500 after its fourth month in business.
The new store will sell 2300 items in its fourth month in business.
Answer:
It will be 4500
Step-by-step explanation:
Just substitute 4 for x in both equations and you will get:
r(4) = $5,000 store's revenues in 4 months
c(4) = $500 store's expenses in 4 months.
So, (r - c) = $5,000 - $500 =$4,500 store's profit after 4 months in business.

On a winter day the low temperature in Anchorage, Alaska was -21 degrees Celsius and the low temperature in Minneapolis, Minnesota was -14 degrees Celsius. Jada said: “I know that 14 is less than 21, so -14 is also less than -21. This means that it was colder in Minneapolis than in Anchorage.” Do you agree? Explain your reasoning.
Jada's reasoning about the temperatures is incorrect because in negative numbers, the lower the value, the colder the temperature. Hence, Anchorage at -21°C was colder than Minneapolis at -14°C.
Explanation:Jada's statement that "-14 is also less than -21" is incorrect when referring to temperatures in degrees Celsius. In fact, when we work with negative numbers, especially temperatures, the higher the negative number, the warmer the temperature. That is, -14°C is warmer than -21°C. Therefore, it was actually colder in Anchorage, Alaska at -21°C compared to Minneapolis, Minnesota at -14°C. To understand this better, we can look at a thermometer or a number line where numbers to the right are higher (warmer) than those to the left.

Tonya has 39 packages. Each package weighs 58 pounds. Choose the best estimate of the total weight of the packages
The best estimate for the total weight of the packages is 2262 pounds.
What is Multiplication?Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.
a × b means that a is added to itself b times or b is added to itself a times.
Given that,
Total number of packages that Tony has = 39 packages
Weight of each package = 58 pounds
In order to find the weight of total packages we have to add the weight of each packages.
We have to add the weight of a package 39 times since the number of packages is 39.
That is, we can multiply 39 with 58.
Total weight = 39 × 58 pounds
= 2262 pounds
Hence the total weight of the packages is 2262 pounds.

A- 15.2%
B- 16.6%
C-18.2%
D-21.8%
Answer:
The correct answer is A
Step-by-step explanation:
This results in a 16.6% probability. The correct option is (b).
Explanation:There are 3 individuals (Don, Eric, and Finn) and so 3! (3 factorial) ways to arrange them, which is 3*2*1=6 ways.
The desirable permutation, which is they stand in alphabetical order, is just one way. So, the probability is Number of Favorable Outcomes / Total Number of Outcomes = 1/6.
Thus the correct answer is (1/6) * 100% to convert to a percentage which is approximately 16.6%.

In the equation 0.03x - 0.1 = 2.6 , what is the value of x ?
Look at the attached picture ⤴
Hope it will help u...
Final answer:
To solve the equation 0.03x - 0.1 = 2.6, you add 0.1 to both sides and then divide by 0.03, resulting in the value of x being 90.
Explanation:
In the equation 0.03x - 0.1 = 2.6, to find the value of x, we first add 0.1 to both sides of the equation to isolate the term with x on one side. This gives us 0.03x = 2.7. Next, we divide both sides of the equation by 0.03 to solve for x, which gives us x = 2.7 / 0.03. Therefore, the value of x is 90.
Sheri and Tim are both selling raffle tickets at a volleyball tournament.
The table below shows the total number of raffle tickets Sheri sold at different times of the day.
Tim uses the equation below to show the number of tickets, t, he has sold after h hours.
t = 14h
Which of the following best describes the relationship of these two rates?
A. The rate that Tim sells raffle tickets is half the rate that Sheri sells raffle tickets.
B. The rate that Tim sells raffle tickets is double the rate that Sheri sells raffle tickets.
C. The rate that Sheri sells raffle tickets is 7 times the rate that Tim sells raffle tickets.
D. The rate that Sheri sells raffle tickets is the same as the rate that Tim sells raffle tickets.
Answer:
B is the correct answer
Step-by-step explanation:
Let’s write the equation for Tim according to the question, that is t = 14h
Now for sheri, looking at the table, we can see that in two hours, he sells 14 tickets . This means that he sells at an average rate of 7 tickets per hour
Modeling his selling rate, with t being the number of tickets and h being the number of hours, we have;
t = 7h
Tim’s rate is t/h = 14
While sheri’s rate is t/h = 7
We can see that Tim’s rate is double Sheri’s rate
The rate of a linear function is simply the slope of the function.
The true statement is (b) the rate that Tim sells raffle tickets is double the rate that Sheri sells raffle tickets.
Tim's equation is given as:
[tex]t = 14h[/tex]
A proportional linear equation is represented as:
[tex]t = mh[/tex]
Where m represents the slope/rate.
This means that:
[tex]m = 14[/tex] --- Tim's rate
The slope of Sheri's table is calculated using:
[tex]m = \frac{y_2-y_1}{x_2 - x_1}[/tex]
So, we have:
[tex]m = \frac{28 -14}{12 -10}[/tex]
[tex]m = \frac{14}{2}[/tex]
[tex]m = 7[/tex] ---- Sheri's rate
By comparison:
[tex]14 = 7 \times 2[/tex]
This means that: Tim's rate doubles Sheri's rate.
Hence, the true statement is (b)

Answer:
The only options equivalent to 2:9 are B and C.
Step-by-step explanation:
A ratio is a comparison between two or more numbers.
When two ratios are equivalent, they describe the same relationship between numbers.
An equivalent ratio is to a number is usually the same ratio in which the numerator and denominator (first and second number) have been multiplied by a common multiple.
To find if two ratios are equivalent, we have to put them in their simplest forms and compare.
The ratio we are comparing other ratios with is 2:9
So, we will put all other ratios in their simplest form and see if it gives us 2:9
A. 9:2 - This is already in its simplest form and it is not equal to 2:9.
B. 18:81 - To put this in simplest form, we divide both numbers by 9:
18:81 = 2:9
Hence, this is an equivalent ratio to 2:9.
C. 12:54 - To put this in simplest form, we divide both numbers by 6:
12:54 = 2:9
Hence, this is an equivalent ratio to 2:9.
D. 18:4 - To put this in simplest form, we divide both numbers by 2:
18:4 = 9:2
This is not the same as 2:9.
E. 20:45 - To put this in simplest form, we divide both numbers by 5:
20:45 = 4:9
This is not the same as 2:9.

Find the midpoint of the segment with endpoints (-3,4) and (7,10)
Answer:
(2,7)
Step-by-step explanation:
To find the midpoint, you need to plug the 2 points in to the midpoint formula.
[tex]( \frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )[/tex]. You are basically adding the x values and divided the sum by 2 and doing the same for the y values. To find the x value of the midpoint, you add -3 and 7 which gets you 4, then you divide by 2 which is 2. To find the y value of the midpoint you, you add 4 and 10 which gets you 14, then you divide by 2 which gets you 7. So your mid point is (2,7).
