How much did the two heaviest tomatoes weigh all together?

Answers

Answer:

1 and 6/8

Step-by-step explanation:

1/2 is equivalent to 4/8 when you multiply both the numerator and denominator by 2. So since there are two tomatoes that weigh 1/2 it would be 4/8+4/8= 1. Next you would add 3/8+3/8=6/8. So when you add 1 whole and 6/8 you get 1 and 6/8.

Determine if the statement below is always true, sometimes true, or never true.

The sum of an integer and 10% of the integer is greater than or equal to the integer.

Explain your reasoning.

Answers

Step-by-step explanation:

There are many integers that will satisfy the conditions mentioned. For example, -9 and -2 would satisfy both conditions. These integers are both greater than -10, and when added together, they equal -11, which is less than -10.

Answer:

The statement is true when the integer is positive and false when the integer is negative. Meaning sometimes true would be the answer.

Answer:

  see attached

  use the point-slope form

Step-by-step explanation:

Substitution works to find the solution.

  4x = 3x -3

  x = -3 = y

The solution is (x, y) = (-3, -3).

__

The first equation graphs as a line through the origin with a slope of 1.

The second equation graphs as a line through (0, 1) with a slope of 4/3, that is, a rise of 4 for each run of 3.

The two lines intersect at (x, y) = (-3, -3), so that point, together with the y-intercepts, can be used to draw the lines.

_____

A line that intersects point (-3, -3) can be written in point-slope form as ...

  y +3 = m(x +3) . . . . . for some slope m.

If you were to choose m = -1, this becomes ...

  y +3 = -(x +3)

  y = -x -6 . . . . . . rearranged to slope-intercept form

Answer:

The diagonal is 39.54 in

The baton will fit in the box if it is placed in the direction of the diagonal of the cube since:

39.54 inches > 38 inches

Step-by-step explanation:

Answer: Yes, she could.

Step-by-step explanation:

To find the answer we first have to find the length of the interior diagonal.

I  used Phytagoras' theorem to find the diagonal length of the base of the box. Then to calculate x (hypotenuse), the diagonal length of the box, I again used the Phytagoras' theorem using the length of the base and the height of the box.

I found out that the diagonal interior length of the box is 39.5 in.

Since the baton is 38in and the length of the box is 39.5 in, Kylie can fit the baton inside the box with 1.5 in spare length.

Step-by-step explanation:

The median can be found at the line inside of the box, the heaviest weight would be found at the right end of the line, and the smallest weight would be found at the left, the interquartile range is the difference of one end of the box to the other, and the range is the difference of the largest number of the entire diagram, from the smallest number.

Hope this helps you!

Answer:

Florida: The weight range = 10

Tennessee: The interquartile range = 4

Tennesse: Median Weight = 76

Florida: Median Weight = 80

Florida: Weight of the heaviest child =  84

Tennesse: Weight of the smallest child = 71

Step-by-step explanation:

Florida: How to find the weight range

The range of a data set is the difference between the minimum and maximum. To find the range, calculate xn minus x1.

R = xn − x1

Therefore, the weight range in Florida is 10

Tennessee: How to find the interquartile range

To find the interquartile range (IQR), ​first, find the median (middle value) of the lower and upper half of the data set. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.

71, 72, 73, 74, 75, 76, 77, 78, 79, 80

Q1 = 74

Q2 = 78

78 - 74 = 4

Therefore, the interquartile range in Tennesse is 4

Tennesse: Median Weight

The median x˜ is the data value separating the upper half of a data set from the lower half.

Arrange data values from lowest to the highest value

The median is the data value in the middle of the set

If there are 2 data values in the middle the median is the mean of those 2 values.

x˜ = 75.5

Therefore, the median weight of Tennesse is 76

Florida: Median Weight

The median x˜ is the data value separating the upper half of a data set from the lower half.

Arrange data values from lowest to the highest value

The median is the data value in the middle of the set

If there are 2 data values in the middle the median is the mean of those 2 values.

x˜ = 79

Therefore, the median weight of Florida is 80

Florida: Weight of the heaviest child

Since the smallest number in Florida is 84,

Therefore, the weight of the heaviest child in Florida is 84

Tennesse: Weight of the smallest child

Since the smallest number in Tennesse is 71,

Therefore, the weight of the smallest child in Tennesse is 71
