PLEASE HELP!!!! I DONT UNDERSTAND THIS.
The table and the graph below each show a different relationship between the same two variables, x and y:

A table with two columns and 5 rows is shown. The column head for the left column is x, and the column head for the right column is y. The row entries in the table are 4 comma 80 and 5 comma 100 and 6 comma 120 and 7 comma 140. On the right of this table is a graph. The x-axis values are from 0 to 10 in increments of 2 for each grid line. The y-axis values on the graph are from 0 to 350 in increments of 70 for each grid line. A line passing through the ordered pairs 2 comma 70 and 4 comma 140 and 6 comma 210 and 8 comma 280 is drawn.

How much more would the value of y be on the graph than its value in the table when x = 12?

Maria bought 1/4 pound of ham and 5/8 pound of turkey. How much more turkey than ham did she buy?

Answers

if you multiply 1/4 by 2 it would be 2/8 so if you compare 2/8 and 5/8 she bought 3/8 pounds more
Final answer:

Maria bought 1/4 pound more turkey than ham by calculating the difference between 5/8 pound of turkey and 1/4 pound of ham.

Explanation:

To determine how much more turkey than ham Maria bought, we need to compare the weights of the turkey and the ham. Maria bought 1/4 pound of ham and 5/8 pound of turkey. To find the difference, we subtract the smaller quantity (ham) from the larger quantity (turkey).

First, we need both quantities in the same unit. They are both already in pounds, so we can subtract directly:

5/8 pound (turkey) - 1/4 pound (ham) = 2/8 pound (or 1/4 pound)

Maria bought 1/4 pound more turkey than ham.

Candice has six pairs of jeans she places each pair on its own hanger how many hangers does Candace use

Answers

6 hangers for each pair of jeans.So first you need to count the number of jeans, there are 6 jeans so then you need to get as many hangers as their are jeans there 6 jeans so that means you need 6 hangers so that each Jean gets its own hanger
Final answer:

Candice uses a total of 6 hangers for her six pairs of jeans, with one hanger used for each pair of jeans.

Explanation:

The question is asking to calculate the number of hangers Candice would use if she places each pair of her six pairs of jeans on its own hanger. Since Candice is placing each pair of jeans on a separate hanger, we can easily determine the answer by understanding the one-to-one relationship between pairs of jeans and hangers.

For each pair of jeans, Candice uses one hanger. Therefore, the calculation is straightforward as we simply multiply the number of pairs of jeans by the number of hangers used per pair of jeans, which is one.

Number of jeans pairs: 6Number of hangers used per pair: 1Total number of hangers used: 6 pairs × 1 hanger per pair = 6 hangers

In conclusion, Candice uses 6 hangers to hang her six pairs of jeans.

A lawn had an area of 35 square feet. If it was 7 feet width, how long was it?

Answers

It would be 245. You multiply length x width. 35x 7= 245

When, a lawn had an area of 35 square feet. If it was 7 feet width. Then, the length of the lawn will be 5 feet.

We, can use the area formula for a rectangle, which is area = length x width.

Given the area of the lawn is 35 square feet and the width is 7 feet, we can set up the equation:

Area = Length x Width

35 sq ft = Length x 7 ft

To find the length, you would divide the area by the width:

Length = Area \ Width = 35 sq ft / 7 ft = 5 ft

Therefore, the length of the lawn is 5 feet.

A cart travels 3.6 meters in 1.8 seconds. What is the average speed of the cart?

Answers

For solving this we need the change in distance and the change in time.  You said that the change in time is 1.8 seconds and the change in distance is 3.6 meters.  ( This is assuming it started at 0 meters and started at 0 seconds )

Since the starting was 0,0 we can toss them out as they add no value.  Now since speed is labeled (in this case) m/s, we divide how many meters it traveled over how many seconds it took to travel it.

3.6 / 1.8 = 2

The average speed of the cart is 2 m/s

expression is equivalent to −4.6+(−0.4)+(−7.2)−4.6+(−0.4)+(−7.2) ?

Answers

Final answer:

The expression −4.6+(−0.4)+(−7.2)−4.6+(−0.4)+(−7.2) combines all the like terms for a result of −24.4. You simply add and subtract the negative numbers in pairs and then combine the results.

Explanation:

The mathematical expression in question is −4.6+(−0.4)+(−7.2) −4.6+(−0.4)+(−7.2). This appears to be a straightforward question of addition and subtraction involving negative numbers.

To find the equivalent expression, we can group the like terms and add or subtract them accordingly.

Let's first simplify the expression

−4.6 + (−4.6) = −9.2,−0.4 + (−0.4) = −0.8,(−7.2) + (−7.2) = −14.4.

Now, summing up these results gives us:

−9.2 + (−0.8) + (−14.4) = −9.2 −0.8 −14.4 = −24.4.

The equivalent expression for −4.6+(−0.4)+(−7.2)−4.6+(−0.4)+(−7.2) is simply −24.4.

what percent of 29 is 3?

Answers

You can put this in proportion form. 29 is the whole, so you would have 29 / 100. 3 is only part of it, and you want to know what is the percent for 3, so you would have 3 / x (Or any other variable is fine.)

29 / 100 = 3 / x

Cross multiply and you would get 29x = 300. Divide 300 by 29, and you would get the answer, which is 10.35. The answer would be x = 10.35.

The probability of flipping heads on a coin and then flipping the coin again and getting heads is 0.25 or 25%.

Explanation:

To find the probability of flipping heads on a coin and then flipping the coin again and getting heads, we need to multiply the probabilities of each event. The probability of flipping heads on a fair coin is 0.5. Since each flip of the coin is independent, we can multiply the probabilities together: 0.5 * 0.5 = 0.25. Therefore, the probability of flipping heads on a coin and then flipping the coin again and getting heads is 0.25 or 25%.

                _____
               6.2500     There is 4 numbers right to the decimal point totally....and the answer.  
Final answer:

When multiplying decimals, the decimal in the answer is placed based on the total count of digits following decimals in the original numbers. For example, multiplying 0.4 by 0.20 gives 0.08, not just 8.

Explanation:

When you're multiplying decimals, the placement of the decimal in the answer is determined by the total number of digits behind the decimals in the problems you're multiplying. For example, if you're multiplying 0.4 (one digit after the decimal) by 0.20 (two digits after the decimal), your answer should have three digits after it. So, let's multiply: 4 times 2 equals 8, but this should be written as 0.08, not just 8, due to the rule. That's how you manage the decimal placement when multiplying decimals.

1:8 is the correct answer because 24 divided by 3 is 8.
Final answer:

The ratio of cereal boxes with prizes to without prizes in this scenario is 1:7, which is option A. This is calculated by dividing the number of boxes with and without prizes by the smallest number (3), resulting in the simplified ratio.

Explanation:

The subject of this question is about understanding mathematical ratios, specifically in the context of a cereal box prize scenario. Here, we are asked to find the ratio of boxes with prizes to boxes without prizes. If 3 out of 24 boxes contain a prize, that means 21 boxes are without a prize.

To find the ratio of boxes with prizes to boxes without prizes, we divide both numbers by the smallest one, which is 3, the number of boxes with prizes. Hence, the ratio is 3:21, which simplifies to 1:7 (since both numbers are divisible by 3). Therefore, the answer to this question is Option A, 1:7.
