9 + 94 + 97 + 86 + x ≥ 450
368 + x ≥ 450
368 - 368 + x ≥ 450 - 368
x ≥ 82

Answers

Answer 1

Answer:

Step-by-step explanation:

9 + 94 + 97 + 86 + x ≥ 450

368 + x ≥ 450

368 - 368 + x ≥ 450 - 368

x ≥ 82

Answer 2
According to my calculations, the answer should be greater than or equal to 82

What will be the actual dimensions of Laurie’s garden?

Answers

The dimensions in ft will go from 8cm by 4cm to, 21.25ft by 10

1/2 is 0.5 as a decimal. So 8.5 multiplied by 2.5 is 21.25, 4 multiplied by 2.5 is 10.

Answer:

The length is 10 and the width is 21.25

Step-by-step explanation:

You time 2.5 × 4 = 10 to get the width

You time 2.5 × 8 = 20 and 1 half of 2.5 is 1.25.

So you add 20 + 1.25 = 21.25 and that is your width.

So the answer is length is 10 and width is 21.25

Answer:

A; .31 + 31%

Step-by-step explanation:

What I did: I put 17,172 over 55,208 as a fraction and to get the percentage I compared the denominator to 100, after this you multiply 17,172 by 100 then divide that by 55,208 to get 31.1316147 which rounds out to 31, once you put that over the 100 that is the percentage ( I may not have explained it the best way possible or the most efficient method, but thats how I got my answer ).

Answers

Absolute value makes the number positive, so now you have -5+18, then adding a negative to a positive is the same as subtracting. Therefore, 18-5=13. Answer should be A}
-5 + 18 = 13 A because the absolute value cancels out the negative on the 18 meaning you could just take away 5 from 18 leaving you with 13

Answer:

Step-by-step explanation:

nyjnnndd

Given statement solution is :- The median is the middle value when the data is arranged in ascending order. Since we have an even number of values (10 in total), the median is the average of the two middle values. In this case, the middle values are 3 and 4. Therefore, the median is (3 + 4) / 2 = 3.5 pounds.

To find the median of the given data set, we need to arrange the values in ascending order:

0, 0, 1, 2, 3, 4, 4, 5, 7, 8

The median is the middle value when the data is arranged in ascending order. Since we have an even number of values (10 in total), the median is the average of the two middle values. In this case, the middle values are 3 and 4. Therefore, the median is (3 + 4) / 2 = 3.5 pounds.
