Joelle is working on a school report in a word processor. She wants to place a figure which is 13.09 cm wide so that it appears centered on the page. The width of the page is 21.59 cm.
How much margin should she leave on the left so that the figure is centered?
Do I divide the width by 13.09 to get the answer? Not very sure
Answers
Answer:
The answer is 4.25 cm.
Step-by-step explanation:
Given is - Joelle wants to place a figure which is 13.09 cm wide so that it appears centered on the page. The width of the page is 21.59 cm.
To solve, this first we will 13.09 from the 21.59, and then divide that number in half to find the left and right margin.
[tex]21.59-13.09=8.5[/tex]
[tex]\frac{8.5}{2}= 4.25[/tex]
Therefore, the answer is 4.25 cm.

Draw or write to show that the number 18 is an even number
Answers
The number 18 is considered an even number because it can be divided by 2 to result in another integer. This is confirmed by writing 18 as 2 times 9, which results in an even product.
Explanation:In mathematics, an even number is any integer that can be exactly divided by 2 without leaving a remainder. For example, the numbers 2, 4, 6, 8, and 10 are even because each can be divided by 2 to result in another integer. If you divide an even number by 2, the result is always a whole number, and that's not the case with odd numbers. Let us examine the number 18.
If we write 18 as 2 times 9, we see that it has been turned into a product of 2 and another integer (9, in this case). This indicates that 18 is indeed an even number. Therefore, we can be sure of the fact that the number 18 is an even number, because it can be divided by 2 without leaving a remainder.

A school PTA wants to rent a dunking tank for its annual fundraising carnival. The cost is $80 for the first three hours and then $19.75 for each additional hour or part thereof. How long can the tank be rented if up to $200 is budgeted for this expense?
Answers
The tank can be rented for maximum of 6 hours.
We have school PTA wants to rent a dunking tank for its annual fundraising carnival. The cost is $80 for the first three hours and then $19.75 for each additional hour or part thereof.
We have to determine how long can the tank be rented if up to $200 is budgeted for this expense.
The critical level for the number of bacteria spread is 1000. Starting from 500, if the bacteria count rises by 5 every second, then determine whether after 30 seconds the critical level is passed or not?Initial count = 500
Count increasing per second = 5
Critical level = 1000
Assume that the bacteria count after t seconds is y. Then -
y = 500 + 5t
for t = 30 ↔ y = 150 + 500 = 650 < 1000 → Critical level not passed.
According to question, we have -
Cost for first three hours = $80
Cost for additional hour = $19.75
Total Budget = $200
Assume that the tank can be bought for 'n' hours. Then -
80 + 19.75n ≤ 200
Solving the inequality -
19.75n + 80 - 80 ≤ 200 - 80
19.75n ≤ 120
n ≤ 6.07
or
n ≤ 6
Hence, the tank can be rented for maximum of 6 hours.

60,488 rounded to the nearest 10,000
Answers
With the 488 it would be rounded for the nearest hundredth to 500 then if you had to round it to the nearest 1,000 from 60,500 it would be 61,000
So even with 61,000 rounded to the nearest 10,000 it would still be 60,000 in order to get 70,000 it would need to be 65,000 and anything above to be rounded to the 70,000 mark.

In the number 555.55 each digit is a 5 but the value of each 5 is different based on its place in the number. How does the value of the 5 in the tenths place compare to the value of the underlined digit 5
Answers
The value of each 5 in the number 555.55 depends on its place value. A 5 in the tenths place (representing 1/10 or 0.1) would have a much smaller value compared to a 5 in the hundreds place in the same number, due to the multiplying factor of ten for each place value.
Explanation:In the number 555.55, each digit is indeed a 5. However, the value of each 5 changes depending on its place value. The tenths place, to the right of the decimal point, represents tenths or 1/10 (0.1).
If the underlined digit 5 is in the hundreds place, for example, it will have a value of 500. To compare, the value of the 5 in the tenths place (which is 0.5) is much smaller than the value of the 5 in the hundreds place. In fact, it's 1,000 times smaller because each move to the left in place value multiplies the digit by 10.

Answers
s+6 + s+6 + s + s + 2s = 102
solve for s:
6s + 12 = 102
6s = 90
s= 15
The lengths of sides are as follows:
15, 21, 21, 15, 30 inches
I hope that helps!
Answer:
The length of each side is 21 inches, 21 inches, 15 inches, 30 inches and 15 inches.
Step-by-step explanation:
Consider the provided figure.
It is given that the perimeter of a school crossing sign is 102 inches.
The figure have 5 sides having the length s+6, s+6, s, 2s and s.
Now the perimeter is the sum of all sides,
s+6+s+6+s+2s+s=102
6s+12=102
6s=102-12
6s=90
s=15 inches
The length of each side is:
s+6=15+6=21 inches
s+6=15+6=21 inches
s=15 inches
2s=2×15=30 inches
s=15 inches
Hence, the length of each side is 21 inches, 21 inches, 15 inches, 30 inches and 15 inches.

Noel Devine bought a new dishwasher for $320. He paid 20 down and made 10 monthly payments of $34 what actual yearly interest rate did Noel pay?
Answers
Interest= Principal x Rate x Time or I= PRT
Substitute values: I= [$20 + ($10 x $34)] -320 =$40
P= $320
R=?
T=10 months/year
I=PRT
Since R is a missing term, we will solve for R using this formula: R=I/PT
R= [$20 + ($10 x $34)-320] / ($320 x 10 months)
T=10 months÷12 months=0.83
R= ($40)/ $320 X 0.83
R= 40/ 265.6
R=15.06024096
Amount financed
320-20=300
Total payments
34×10=340
Total interest=total payments-amount financed
Total interest=340-300=40
Now to find the yearly interest rate use the formula of
I=(2yc)÷(m×(n+1))
I ?
Y number of months in a year 12
C total interest 40
M amount financed 300
N number of payments 10
I=(2×12×40)÷(300×(10+1))
I=0.2909×100=29.09%

Write the equation of the sphere in standard form. 2x2 + 2y2 + 2z2 = 12x − 24z + 1
Answers
[tex](x-a)^2 + (x-b)^2 + (x-c)^2 = r^2[/tex]
Now, the given equation is :
[tex]2x^2 + 2y^2 + 2z^2 = 12x - 24z + 1 \\ 2x^2 + 2y^2 + 2z^2 - 12x + 24z - 1 = 0 \\[/tex]
combine the x, y and z terms and complete the square for each variable
[tex](2x^2 - 12x) + 2y^2 + (2z^2 + 16z) = 1 \\ (x^2 - 6x) + y^2 + (z^2 + 8z) = 1/2 [/tex]
complete square for x by adding 9 to both sides
we do not complete square for y because there is not a translation on that axis
complete square for z by add 16 to both sides
[tex] (x^2 - 6x + 9) + y^2 + (z^2 - 8x + 16) = 1/2 + 9 + 16 \\ (x - 3)^2 + y^2 + (z - 4)^2 = 25 1/2[/tex]
[tex] (x-a)^{2}+ (y-b)^{2}+ (z-c)^{2}=r^{2}[/tex]
We have the equation:
[tex]2x^2+2y^2+2z^2=12x-24z+1[/tex]
which can be regrouped to fit the standard form, using completing the square as follows:
first divide both sides by 2
[tex]x^2+y^2+z^2=6x-12z+ \frac{1}{2} \\\\(x^2-6x)+y^2+(z^2+12z)= \frac{1}{2}\\\\(x^2-2\cdot3\cdot x)+y^2+(z^2+2 \cdot6 \cdot z)= \frac{1}{2}\\\\(x^2-2\cdot3\cdot x+3^2)-3^2+y^2+(z^2+2 \cdot6 \cdot z+6^2)-6^2= \frac{1}{2}\\\\(x-3)^2+y^2+(x+6)^2=9+36+0.5\\\\(x-3)^2+y^2+(x+6)^2=45.5\\\\\(x-3)^2+y^2+(x+6)^2=( \sqrt{45.5} )^2[/tex]
Answer: [tex](x-3)^2+y^2+(x+6)^2=( \sqrt{45.5} )^2[/tex]
