Answer:

120 blocks total

Step-by-step explanation:

All of the little cubes have side length 2" Thus, the 11" height of the box cannot be used entirely: we waste the top 1" because the five layers of little cubes reach only to 10" from the bottom.

Start at the bottom of the box. The dimensions of the bottom are 12" by 8". Along the longer side we can lay 6 blocks (which add up to 12" and are 2" wide. We can add 3 more such rows to fill the available 8" width of the box bottom. That's 6*4, or 24 blocks.

We can add 4 more 6 block by 4 block layers before we have the maximum 5 layers stacked in the box.

5 layers times 24 blocks per layer comes to 120 blocks total.

Here is to my last q

Answers

Mode: value that occurs most
Mean: average (add all values then divide by the amount of number)
Median: middle number

Mode: 80 (appears the most)
Mean: 95 + 80 + 80 + 85 + 80 + 85 + 90 = 595/7 = 85, the mean is 85
Median first put them in order
80, 80, 80, 85, 85, 90, 95
The median is the middle which is 85

Which statement matches?

Solution: D

Answer: D (Mean is 85)

Explanation:

"The list below shows the quiz scores for a group of students.

95, 80, 80, 85, 80, 85, 90"

The choices talk about median and mode so we find those first:

Median: find by taking which is the middle number when the data is from low to highest

1) rearrange them from low to high

80, 80, 80, 85, 85, 90, 95

2) find middle number

80, 80, 80, 85, 85, 90, 95

The median is 85

Mean: mean is the average of all numbers. Find by adding numbers and dividing by amount of numbers

1) add 80, 80, 80, 85, 85, 90, 95 and get 595

2) There are 7 total numbers so do 595/7 = 85

The mean is 85

D is the correct answer

why?

A is wrong because they are 85 not 80

B is wrong because it is 85 not 80

C is wrong because it is 85 not 80

D is right because it is 85!

You can see the picture for the steps but I’m sure the answer is -72

Answer:

x = -72

Step-by-step explanation:

Using algebra:

⇒ [tex]-\frac{x}{8} -11 = 2[/tex] (First add 11 to both sides of "=")

⇒ [tex]-\frac{x}{8} =9 (11 + -2)[/tex] (The multiply both sides by "8")

⇒ [tex]-x = 9*8[/tex] (Lastly the answer is 72 when x-value is negative, so when x-value will be positive the answer will be opposite of 72 which is -72)

⇒ [tex]x = -72[/tex]

Here is Laila’s graph from the previous screen.

Write your own equation in the form y=mx+b that could represent Laila’s graph.

Answers

Answer:

y=-1/3x+8

Step-by-step explanation:

There is no need for any specific answers, but here is one that could logically work out. Since the graph is going left/down, it has a negative slope, so -1/3 would be reasonable. The graph doesn't cross the origin and crosses above it, so this equation must have a positive 'b' value. In this case, I chose 8. y=-1/3+8 could represent Laila's graph.
