A checkers board is 8 squares long and 8 squares wide. The area of each square is 14 square centimeters. Estimate the perimeter of the checkers board to the nearest tenth of a centimeter.
Area of each square = 14 sq. cm.
length of each square = sqrt(14) = 3.7 cm
length of one side = 8 x 3.7 = 29.6 cm
Perimeter of the checker board = 4 x 29.6 = 118.4 cm
The perimeter of the checker board 118.4 cm
Area of each square = 14 sq. cm.
What is the length?
The square root of area is the length of one side
[tex]length of each square =\sqrt{14} = 3.7 cm[/tex]
[tex]length of one side = 8 * 3.7 = 29.6 cm[/tex]
What is the formula for perimeter of square?Perimeter (P) =4 (length of side a)
[tex]P=4a[/tex]
[tex]Perimeter of the checker board = 4 *29.6 = 118.4 cm[/tex]
Therefor we get the perimeter of the checker board 118.4 cm

2x+3y=36
y=6
2x +3(6) = 36
2x +18 =36
2x = 18
x = 9
Answer:
The value of the provide expression is 9.
Step-by-step explanation:
Consider the provided expression.
[tex]2x + 3y = 36 [/tex]
We need to find the value of the expression, for x when y=6
Substitute the respective values in the provided expression.
[tex]2x + 3(6) = 36 [/tex]

Hence, the value of the provide expression is 9.
ΔABC with vertices A(-3, 0), B(-2, 3), C(-1, 1) is rotated 180° clockwise about the origin. It is then reflected across the line y = -x. What are the coordinates of the vertices of the image?
Answer:
A(0, -3) ; B(3, -2) and C(1, -1).
Step-by-step explanation:
Given : ΔABC with vertices A(-3, 0), B(-2, 3), C(-1, 1) is rotated 180° clockwise about the origin.
To find : What are the coordinates of the vertices of the image.
Solution : We have given
Vertices A(-3, 0), B(-2, 3), C(-1, 1) is rotated 180° clockwise.
By the rotation rule of 180° clockwise : (x ,y) →→ ( -x ,-y).
Then vertices would be
A(-3, 0) →→ A(3, 0)
B(-2, 3) →→ B(2, -3)
C(-1, 1) →→ C(1, -1).
Reflection y = -x then
A(0, -3) ; B(3, -2) and C(-1, 1).
Therefore, A(0, -3) ; B(3, -2) and C(1, -1).

Newer stocks can be bought for $8 each, while older stocks can be bought for $4 each. The total cost, in dollars, of 10 stocks is represented by the expression 8s+4(10-s), where s represents the number of new stocks bought. how does changing the value of s change the value of the term 4(10-s)?
A.) For values of s less than 10, the term 4(10-s) will be negative; for values of s greater than 10, the term will be negative; for values of s equal to 10, the term will equal 0.
B.) For values of s less than 10, the term 4(10-s) will be negative; for values of s greater than 10, the term will be positive; for values of s equal to 10, the term will equal 0.
C.) For values of s less than 10, the term 4(10-s) will be positive; for values of s greater than 10, the term will be positive; for values of s equal to 10, the term will equal 0.
D.) For values of s less than 10, the term 4(10-s) will be positive; for values of s greater than 10, the term will be negative; for values of s equal to 10, the term will equal 0.
A survey was taken on pet ownership. 750 people were covered on the first day of the survey. The number tripled every subsequent day. Find the total number of people surveyed in 6 days
A. 265100
B. 265200
C. 273000
D. 265700
To find the total number of people surveyed in 6 days with numbers tripling each day starting with 750, we calculate the number for each day and sum them up, giving a total of 273000 people surveyed.
To calculate the total number of people surveyed in 6 days if 750 people were covered on the first day and the number tripled every subsequent day. We will use an exponential growth formula to find the answer.
On Day 1: 750 people.
On Day 2: 750 × 3 = 2250 people.
On Day 3: 2250 × 3 = 6750 people.
On Day 4: 6750 × 3 = 20250 people.
On Day 5: 20250 × 3 = 60750 people.
On Day 6: 60750 × 3 = 182250 people.
To find the total number of people surveyed over the 6 days, we add up the total number of people surveyed each day:
750 + 2250 + 6750 + 20250 + 60750 + 182250 = 273000 people.
Therefore, the correct answer is C. 273000.
There are 20 girls on the basketball team. of these, 17 are over 16 years old, 12 are taller than 170 cm, and 9 are both older than 16 and taller than 170 cm. how many of the girls are older than 16 or taller than 170 cm?
Final answer:
By using the principle of inclusion-exclusion, we calculate that all 20 girls on the basketball team are either over 16 years old or taller than 170 cm, as the sum of the individual criteria minus the intersection equals the total number of girls on the team.
Explanation:
To determine how many of the girls on the basketball team are either over 16 years old or taller than 170 cm, we can use the principle of inclusion-exclusion. According to the information provided, there are 20 girls on the team in total, of which 17 are over 16 years old, 12 are taller than 170 cm, and 9 satisfy both criteria. The principle of inclusion-exclusion states that the number of elements in the union of two sets is equal to the sum of the sizes of each set minus the size of their intersection.
Using this principle:
Number of girls over 16 years old: 17
Number of girls taller than 170 cm: 12
Number of girls who are both over 16 and taller than 170 cm: 9
The calculation would be as follows:
17 (over 16) + 12 (taller than 170 cm) - 9 (both) = 20
Therefore, there are 20 girls on the team who are either older than 16 or taller than 170 cm.

Elliott purchased shares of Microsoft in 2008 for $28 per share. He plans to sell them as soon as the price rises 20%. At what price will he sell his shares?
Since we are to find the price when it is risen 20%, therefore the fractional increase must be 0.20 of the original, therefore:
amount increased = $28 * 0.20 = $5.60
So the selling price must be:
selling price = $28 + $5.60 = $33.60
Final answer:
Elliott will sell his Microsoft shares at a price of $33.60 each after a 20% price increase from his initial purchase price of $28 per share.
Explanation:
The question concerns the calculation of a future selling price of shares after a certain percentage increase. To find the selling price after a 20% increase on Elliott's initial purchase price of $28 per share, we first calculate the 20% increase, which is 0.20 × $28 = $5.60. Next, we add this increase to the original purchase price to determine the selling price: $28 + $5.60 = $33.60 per share. Therefore, Elliott plans to sell his shares when their price reaches $33.60 each.

Jade wants to buy a $200,000 term life insurance policy. She is 34 years old. Using the premium table, what is her annual premium for a 10 year policy?
The premium of $200,00 term life insurance policy is $1,202
What is Annual premium?Annualized premium is the total amount paid in a year's time to keep the life insurance policy in force. The annualized premium amount of a life insurance policy does not include taxes and rider premiums.
Given, Jade wants to buy a $200,000 term life insurance policy. She is 34 years old.
Jade wants to buy a $200,000 term life insurance policy. She is 34 years old.
Since, Jade is female.
Using table for 10-year policy: We will see the column of female.
Annual premium of life insurance per $1000 for 10-years policy term of 34-years old female = $6.01
For $1000 life insurance premium = $6.01
For $1 life insurance premium = $0.00601
For $20000 life insurance premium = 200000 x 0.00601
For $20000 life insurance premium = $ 1,202
Therefore, The premium of $200,00 term life insurance policy is $1,202

Describe the cross section
Answer:
D. Square
Step-by-step explanation:
A cross section is the shape that we get when we cut the object.
Here the given object is a cube.
It is cut straight through the middle.
Imagine a cube cut through the middle, when we look at the same on the top, we get square.
Since in a cube all the sides are equal.
Therefore, we get square when we cut the cube straight through the middle.
Answer: D. Square.
The cross-section of the shape in the image is a square.
Here's why:
The shape in the image is a cube.
A cube has six square faces.
When you cut a cube through the middle along any of its axes, the resulting cross-section will always be a square.
Therefore, the answer is D. square.

To graph the linear equation find the intercepts
we know that
The x-intercept is the value of x when the value of the function is equal to zero
The y-intercept is the value of the function when the value of x is equal to zero
so
Find the y-intercept
for [tex]x=0[/tex]
[tex]f(x)=\frac{3}{4}*0+2=2[/tex]
the y-intercept is the point [tex](0,2)[/tex]
Find the x-intercept
