you stop for lunch at a local pizza ahop where each pizza is cut into 8 sices. would your hunger be better satisifued with one slice from a 10 inch pizza or 2 slices from a 8 inch pizza and explain why?
Answer:
Hello there! How are you doing? I am doing fine! I'll answer the question now.
So basically, your hunger would be satisfied with the 2 slices of 8 inches, because although one slice of 8 inches is two inches less than the 10 inch slice. But then you could add another 8 inch slice and it would make it greater and bigger than the one 10 inch slice itself. So in conclusion, the 2, 8 inch slices would be better than the 1, 10 inch slice because 16 inches is greater than 10 inches.
Hope this helped! Your welcome! I can help with other history stuff too! And byee! :)
Step-by-step explanation:
Two slices from an 8-inch pizza provide more pizza than one slice from a 10-inch pizza based on the calculation of the areas of the pizza slices. Therefore, your hunger would be better satisfied with the two pieces from the 8-inch pizza.
Explanation:The subject here is a mathematical comparison of the area of different pizza sizes and the number of slices eaten. The location of a pizza can be calculated using the formula for the circle size, which is πr², where r is the radius of the pizza.
In the case of a 10-inch pizza, the radius is 5 inches (half of the diameter). So the area is π(5)² = 78.5 square inches. One slice of this pizza would be 1/8th of the total area, approximately 9.81 square inches.
For an 8-inch pizza, the radius is 4 inches. So the area is π(4)² = 50.24 square inches. Two slices of this pizza would amount to 1/4th of the total area, approximately 12.56 square inches.
So, when it comes to fulfilling your hunger at lunch, two slices of an 8-inch pizza would be more satisfying as it offers more pizza than one slice of a 10-inch pizza.

Which of the following expressions are equivalent to (x + y) - z
Choose all answers that apply:
A. z + (x + y)
B. x + (y − z)
C. None of the above
Final answer:
Option B: x + (y - z) is equivalent to the given expression (x + y) - z, applying the principles of associativity of addition and subtraction.
Explanation:
The question asks which of the given expressions are equivalent to (x + y) - z. To find the equivalent expressions, we need to apply the principles of commutativity and associativity of addition and subtraction.
Option A: z + (x + y) is not equivalent because the order of operations affects the result due to the subtraction of z. By combining z at the beginning, it implies adding before subtracting z, which alters the outcome unless z is explicitly negated.
Option B: x + (y - z) is equivalent. You can alter the grouping of addition due to associativity (x + y) - z = x + (y - z). Subtracting z directly from y before adding to x does not change the result.
Option C: None of the above is incorrect because Option B is indeed equivalent to the original expression.
Therefore, the expression that is equivalent to (x + y) - z is Option B: x + (y - z).
Rewrite in polar form x^2 + y^2 - 6y - 8 = 0
Answer:
The correct answer option is [tex]r^2-6rsin(\theta)=8[/tex].
Step-by-step explanation:
We are given the following equation and we are to rewrite it in polar form:
[tex]x^2 + y^2 - 6y - 8 = 0[/tex]
[tex]\left \{ {{x^2+y^2=r^2} \atop {y=rsin \theta}} \right.[/tex]

Darlene spent 20 minutes jogging and 10 minutes cycling and burned 400 calories . The next day she did 10 minutes of jogging and 20 minutes of cycling and burned 350 calories . How many calories were burned for each minute of jogging and how many for each minute of cycling
This is very spread out just to show properly but you could get it smaller haha
In this algebra problem, we created two equations from the problem and solved them simultaneously, finding that Darlene burns 15 calories per minute jogging and 10 calories per minute cycling.
Explanation:This question is about working out two equations using two variables, a classic application in
algebra
. Let's call the calories burned per minute jogging as
J
, and the calories burned per minute cycling as
C
. From the information given in the question, we know that:
20J + 10C = 40010J + 20C = 350These equations can be solved simultaneously. To make things easier, let's multiply the second equation by 2, which gives us:
20J + 40C = 700By subtracting equation 1 from this, we get:
30C = 300
, simplifying this, we find that
C = 10 calories per minute for cycling
. Substitute C=10 into the first equation, we get:
20J + 100 = 400
, which simplifies to
J = 15 calories per minute for jogging
. Thus, Darlene burns 15 calories for each minute of jogging and 10 calories for each minute of cycling.

Simplify the expression. Write your answer as a power.
(−5/7)^8⋅(−5/7)^9
Answer: [tex](-\frac{5}{7})^{17}[/tex]
Step-by-step explanation:
The expression can be simplified by applying the a properties of exponents, specifically the Product of powers, which states that:
[tex](b^a)(b^c)=b^{(a+c)[/tex]
Where b is the base and a and c are exponents.
Then simplify it by rewriting the base ([tex]-\frac{5}{7}[/tex]) and adding the exponents of the expression (8 and 9).
You will get the expression simplified and written as a power:
[tex](-\frac{5}{7})^8(-\frac{5}{7})^9=(-\frac{5}{7})^{(8+9)}=(-\frac{5}{7})^{17}[/tex]
Final answer:
To simplify the expression [tex](- 5/7)^8\times (- 5/7)^9[/tex], add the exponents of the same base to get [tex](-5/7)^{17}[/tex], which is the simplified expression written as a power.
Explanation:
To simplify the expression and write the answer as a power when you have [tex](- 5/7)^8\times (- 5/7)^9[/tex], you can use the property of exponents that states when you multiply expressions with the same base, you add their exponents.
This means the simplified expression will be [tex](- 5/7)^8[/tex]+9, which equals [tex](-5/7)^{17}[/tex]. The negative base raised to an odd power remains negative, resulting in a negative final answer.
Find last years salary if after 3% pay raise, this years salary is $34505
Answer:
$34,505
s = --------------- = $33,500
1.03
Step-by-step explanation:
Last year's salary was 1.00 s.
A 3% pay raise would thus amount to 0.03s.
This would equal this year's salary: $34,505.
Thus, 1.03s = $34,505; find s, which was last year's salary.
Dividing both sides by 1.03, we get:
$34,505
s = --------------- = $33,500

Answer: 30
Step-by-step explanation: First of all, you need to know that the angle at hand is a right angle which measures up to 90 degrees. Knowing this, subtracting 90-30 will give you the result of 60 which is the measure of the unknown angle. Now, you know that 60=2x, so divide both sides by 2 and you get 30=x.

Answer:
I think the D equals one (1) based on the info i was given
Step-by-step explanation:
Answer:
d = 6 units
Step-by-step explanation:
Circumference of the circle is given by:
[tex]C = \pi d[/tex]
where, d is the diameter of the circle.
As per the statement:
Given a circle 1 with measures of (C, d, and r) and a circle 2 with measures of (C', d', and r').
Circumference of a circle(C) 1 with diameter(d) is given by:
[tex]C = \pi d[/tex] .....[1]
Also, the circumference of a circle (C') 2 with diameter(d') is given as:
[tex]C' = \pi d'[/tex]
Divide equation [1] and [2] we have;
[tex]\frac{C}{C'} = \frac{\pi d}{\pi d'}[/tex]
⇒[tex]\frac{C}{C'} = \frac{d}{d'}[/tex]
Substitute the given values [tex]\frac{C}{C'}=12[/tex] and d' = 0.50 then;
[tex]12 = \frac{d}{0.50}[/tex]
Multiply both sides by 0.50 we have;
6 = d
or
d = 6 units
Therefore, the value of d is, 6 units

Answer:
The value of x is 13
Step-by-step explanation:
* Lets study the to circles
- The are congruent
- The length of chord TS equal to the length of chord UV
- The measure of the minor arc TS equal to the measure
of minor arc UV
- The measure of the major arc TS equal to the measure
of major arc UV
* We now that the measure of any circle = 360°
∴ The sum of the measure of the minor arc and the measure
of the major arc equal to 360°
* In circle Q:
∵ The measure of the major arc UV is 22x - 13°
∵ The measure of the minor arc UV is 10x - 43° ⇒ circle R ≅ circle Q
∵ The sum of the measure of the two arcs = 360°
∴ 22x - 13 + 10x - 43 = 360 ⇒ add the like terms
∴ 32x - 56 = 360 ⇒ add 56 to both sides
∴ 32x = 416 ⇒ divide both sides by 32
∴ x = 13
* The value of x is 13

How do I find the volume
Answer:
[tex]\large\boxed{V=\dfrac{256\sqrt3}{3}\ cm^3}[/tex]
Step-by-step explanation:
The formula of a volume of a square pyramid:
[tex]V=\dfrac{1}{3}(b^2)(H)[/tex]
b - edge of a base
H - height
We have b = 8cm and the triangle 90 - 60 - 30. The sides of that triangle are in ptoportion 1 : √3 : 2 (look at the picture).
From the picture we have
[tex]a=\dfrac{b}{2}\to a=\dfrac{8}{2}\ cm=4\ cm[/tex]
Therefore
[tex]H=a\sqrt3\to H=4\sqrt3\ cm[/tex]
Substitute:
[tex]V=\dfrac{1}{3}(8^2)(4\sqrt3)=\dfrac{1}{3}(64)(4\sqrt3)=\dfrac{256\sqrt3}{3}\ cm^3[/tex]
To find the volume of any cube you need to know the length, width and height. The formula to find the volume multiplies the length by the width by the height. The good news for a cube is that the measure of each of these dimensions is exactly the same. Therefore, you can multiply the length of any side three times.

the Smith wants to buy a new computer. The regular price is $765 .The store is offering a 30% discount and the sales tax of 6% is added after the discount. What is the final cost of the TV
Answer:
567.63
Step-by-step explanation:
To find the discount, take the original price times the discount percent
discount = 765*30%
= 765 *.3
=229.5
The new price is the original price minus the discount
new price =765-229.5
=535.50
Now we need to find the tax. Tax is the new price times the tax rate
tax =535.5 * 6%
535.5*.06
32.13
To find the final price. we add the tax to the new price
final price = new price + tax
=535.5+32.13
567.63

Blake ate 2/6 of a pumpkin pie and give 3/6 of the pie to his sister. What fraction of the pumpkin pie was left?
Final answer:
After Blake ate 2/6 of a pumpkin pie and gave another 3/6 to his sister, the fraction of the pie that was left is calculated by subtracting the total part taken away (5/6) from the whole pie (1), resulting in 1/6 of the pie remaining.
Explanation:
The question asks about determining the fraction of a pumpkin pie left after Blake ate 2/6 of it and gave another 3/6 to his sister. To calculate the remaining portion of the pie, we add the fractions that were eaten and given away, and subtract that sum from the whole pie, which is represented as 1 (or 6/6, since we are working with sixths).
2/6 (eaten by Blake) + 3/6 (given to his sister) = 5/6. This means 5/6 of the pie was either eaten or given away.
To find the fraction of the pie that was left, we subtract the portion that is gone from the whole. Since 5/6 of the pie was no longer available, subtracting this from 1 (the whole pie) gives us 1 - (5/6) = 1/6. Therefore, 1/6 of the pumpkin pie was left.
A number is chosen at random from the positive, even integers from 2 to 50. Find the probability that the number chosen is divisible by 3 or 8
Answer:
2/5
Step-by-step explanation:
it is 2/5
Probability = 12/25 or 48%.
To find the probability that a number chosen at random from the positive, even integers from 2 to 50 is divisible by 3 or 8, we need to count the number of even integers within this range that are divisible by 3 or 8, and then divide this count by the total number of even integers in the range.
First, let's find how many even integers between 2 and 50 are divisible by 3.
The even integers divisible by 3 in this range are: 6, 12, 18, 24, 30, 36, 42, 48.
Count: 8
Now, let's find how many even integers between 2 and 50 are divisible by 8.
The even integers divisible by 8 in this range are: 8, 16, 24, 32, 40, 48.
Count: 6
Notice that 24 and 48 are counted twice because they are divisible by both 3 and 8. We only want to count them once.
So, the total count of even integers between 2 and 50 that are divisible by 3 or 8 is 8 (from being divisible by 3) + 6 (from being divisible by 8) - 2 (counting 24 and 48 once) = 12.
Now, we calculate the total number of even integers between 2 and 50:
Total even integers between 2 and 50 = (50 - 2) / 2 + 1 = 25
Now, we can calculate the probability:
Probability = (Number of favorable outcomes) / (Total number of outcomes)
= 12 / 25
= 0.48
So, the probability that a number chosen at random from the positive, even integers from 2 to 50 is divisible by 3 or 8 is 0.48.
