What is the solution to √8 to the nearest integer?
Answers
Answer:
3
Step-by-step explanation:
Hence the (positive) square root of 8 is somewhere between 2 and 3 . Since 8 is much closer to 9=32 than 4=22 , we can deduce that the closest integer to the square root is 3 .
Hope it helps :))
Answer:
\(\sqrt{8}\) to the nearest integer = 3
Step-by-step explanation:
If we calculate the square root of 8, we find a value of 2.828.
Because, we are including integers, then we can conclude that the two integers in play for the square root of 8 ( √8 ) are 2<2.828<3, hence 2 and 3. (2 is less than 2.828, and 2.828 is less than 3.
Now we play with both integers:
Integer ( 2 )= 2*2=4 4=22
Integer (3) = 3*3=9 9=32
Conclusion; 22=4<8<9=32

Tokens are put on some squares of an 8 x 8 grid to make a pattern, such as the one shown in the first diagram (without arrows.
We try to remove the tokens in a sequence of clearing steps. A clearing step consists of choosing row or a column which only contains 1 or 2 tokens and removing them. For example, we cannot initially remove all tokens from Column D. But we can clear Row 5 and then, in some later step, remove the two remaining tokens in column D.
If all the tokens in a oattern can be removed from the grid using some sequence of clearing steps, the pattern is called clearable. The pattern in the diagram is clearable because we can remove all tokens using the following sequence of 13 steps (among other possibilites) :
2, E, 8, G, 7, F, D, 5, 6, 3, 4, A, 1.
These steps are represented by the arrows numbered 1 - 13 in the second diagram.
a) Show that the pattern can be cleared in 11 steps.
b) Explain why it is impossible to clear the pattern in less than 11 steps.
c) The third diagram/pattern is not clearable - explain why.
d) What is the smallest number of tokens that can appear in a non-clearable pattern? Explain.

Two friends plant a tree and record the height of the tree each following year to track its growth. The data can be represented by the linear model y = 4.3z +3.25, where y represents the height of the tree, in feet, and z represents the number of years since it was planted.
Based on the linear model, what is the expected height of the tree in 8 years?
3.25
4.3
31.2
37.65
Answers
Answer:
D.) 37.65
Step-by-step explanation:
I know that 8 is an input based on this word problem. So, then I plug in the 8 for z and solve to find the expected height of the tree in 8 years.
y=4.3z+3.25
y=4.3(8)+3.25
y=34.4+3.25
y=37.65
In 8 years the expected height of the tree is 37.65

Erion plans to tile the floor of his kitchen. The kitchen is 11 feet by 15 feet. The tiles he will be using are square, measuring 8 inches on each side, and are sold in boxes that contain enough tile to cover 25 square feet. How many boxes of tiles must he order to complete the job?
Answers
Answer:
First, find the area for the kitchen floor: 16.5*15=247.5 squared feet
Then find the area for one tile: 0.5*0.5=0.25 squared feet
Finally, divide the mayor area between the minor: 247.5/0.25= 990 tiles.
Also you can do it in this another way:
First, divide length of the kitchen floor between the length of one tile: 16.5/0.5=33
Then, do the same for the height: 15/0.5=30
Finally multyply both results: 33*30= 990 tiles.
Step-by-step explanation:

1) Each lunch for a school field trip has a turkey, roast beef, or bologna sandwich, an orange or apple for a fruit, and a cookie or muffin for dessert. Amanda and Zack would like to…
-know the number of possible lunch options.
-P of having any meal with NO COOKIE.
(use sample space, tree diagram, and counting principle)
Answers
1) there are 12 possible lunch options. 2) the probability of having any meal with no cookie is 1/2 or 0.5.
How to find the number of possible lunch options.1) Number of possible lunch options:
To determine the number of possible lunch options, we need to consider the choices for each component of the lunch.
- Sandwich: There are 3 options (turkey, roast beef, or bologna).
- Fruit: There are 2 options (orange or apple).
- Dessert: There are 2 options (cookie or muffin).
Using the counting principle, we multiply the number of options for each component together:
Number of possible lunch options = 3 (sandwich options) × 2 (fruit options) × 2 (dessert options) = 12.
Therefore, there are 12 possible lunch options.
2) Let's examine the favorable outcomes for each component:
- Sandwich: There are still 3 options (turkey, roast beef, or bologna).
- Fruit: There are 2 options (orange or apple).
- Dessert: There is 1 option (muffin, as we want to exclude cookies).
Using the counting principle, we multiply the number of options for each component together:
Number of favorable outcomes (no cookie) = 3 (sandwich options) × 2 (fruit options) × 1 (muffin option) = 6.
The total number of possible outcomes is still 12 (as calculated in the previous step).
Therefore, the probability of having any meal with no cookie is:
P(No cookie) = Number of favorable outcomes / Total number of possible outcomes = 6 / 12 = 1/2 or 0.5.
Hence, the probability of having any meal with no cookie is 1/2 or 0.5.
