Answer:
Square pizza is the better deal.
Step-by-step explanation:
The better deal will be the one that has larger area of pizza. So, find the area of pizza in the case of square pizza and in the case of round pizza.
Below is the calculation of area of pizzas.
[tex]\text{Area of square pizza} = (Side)^{2} \\\text{Area of square pizza} = (12)^2 \\\text{Area of square pizza} = 144 \ in^2 \\[/tex]
[tex]\text{Now area of round pizza.} \\\text{ The area of round pizza} = \pi r^{2} \\\rm Diameter = 12 \\So, \ radius = \frac{12}{2} = 6 \\\text{ The area of round pizza} = \pi r^{2} \\= \frac{22}{7}\times (6)^2 \\= 113.1 \ in^2[/tex]
Since the area of square pizza is greater than round pizza. Thus, square pizza is better deal.

Find all pairs $(x,y)$ of real numbers such that $x + y = 10$ and $x^2 + y^2 = 56$.
Answer:
13.31 and - 3.31
Step-by-step explanation:
(x + y)^2 = x^2 + y^2 + 2xy ; x + y = 10; x^2 + y^2 = 56
This means ;
10^2 = 56 + xy;
100-56 = XY
44 = xy---------(3)
From x + y = 10
x = 10- y
Substitute that in eqn 3;
We have: 44 = (10-y) y
44 =10y - y^2
Y^2-10y -44 = 0;
From formula method of quadratic equation;
Y =[ - (-10) +_ √ (-10)^2 + 4 × 1 x (-44)] / 2 × 1
y = [ 10 +_√ (100 + 176) ]/ 2]
y = [ 10 +_ √ 276]/ 2
y = [ 10 + √ 276]/ 2 or [ 10 _ √ 276]/ 2
y = 13.31 or - 3.31
Similarly x = 10 - 13.31 or 10 - (-3.31)
x = - 3.31 or 13.31
The required ordered pairs are (5+√3, 5-√3) and (5-√3, 5+√3).
Given equations are:
[tex]x+y=10[/tex]......(1)
[tex]x^{2} +y^{2} =56[/tex].......(2)
What is an equation?An equation is a statement that equates to two statements.
On squaring equation (1) we get
[tex]x^{2} +y^{2} +2xy=100[/tex]
From equation(2) [tex]x^{2} +y^{2} =56[/tex]
So, [tex]2xy=44[/tex]
[tex]xy=22[/tex]
[tex]y=\frac{22}{x}[/tex]
Put [tex]y=\frac{22}{x}[/tex] in equation (1)
We get [tex]x+\frac{22}{x} =10[/tex]
[tex]x^{2} -10x+22=0[/tex]
[tex]x=5+\sqrt{3}[/tex]
[tex]x=5-\sqrt{3}[/tex]
If [tex]x=5+\sqrt{3}[/tex],
[tex]y=10-x[/tex]
[tex]y=5-\sqrt{3}[/tex]
So the ordered pair is [tex](5+\sqrt{3}, 5-\sqrt{3} )[/tex]
If [tex]x=5-\sqrt{3}[/tex],
[tex]y=10-x[/tex]
[tex]y=5+\sqrt{3}[/tex]
So the ordered pair is [tex](5-\sqrt{3}, 5+\sqrt{3} )[/tex]
Hence, the required ordered pairs are [tex](5+\sqrt{3}, 5-\sqrt{3} )[/tex] and [tex](5-\sqrt{3}, 5+\sqrt{3} )[/tex].

Dr. Gonzalez is considering joining the Garden Club. If he pays a $25 membership fee, he
can buy rosebushes from the club at a reduced price of $10 each. If he does not join the
club, he can buy rosebushes from a local nursery for $15 each. The graph below compares
the cost of buying rosebushes from the Garden Club and from the local nursery.
Answer:
In the Garden Club the cost will be a fixed fee of $25 and $10 for each rosebush, so if he buys X rosebushes, the total cost will be:
C1(X) = $25 + $10*X
While in the local nursery there is no initial cost, and each rosebush costs $15, so if he buys X rosebushes, the total cost will be:
C2(X) = $15*X
Now, let's find the value of X where C1 and C2 are equal, this is:
$25 + $10*X = $15*X
$25 = $15*X - $10*X = $5*X
X = 25/5 = 5
This means that if he buys 5 rosebushes, he will pay the same amount in both places.
If he buys less than 5 rosebushes, he will pay less in the local nursery (as it has a bigger slope, but no initial fee)
If he buys more than 5 rosebushes, he will pay less in the Garden club (because it has a smaller slope)

Answer:
52+n=m
Step-by-step explanation:
Answer:
6.5 /52 m = n
Step-by-step explanation:
The rate is 6.5 miles / 52 minutes
We are going to run m miles in n minutes
m = 6.5 / 52 * n

Step-by-step explanation:
The local supermarket buys lettuce each day to ensure really fresh produce. Each morning any lettuce that is left from the previous day is sold to a dealer that resells it to farmers who use it to feed their animals. This week the supermarket can buy fresh lettuce for $4.00 a box. The lettuce is sold for $10.00 a box and the dealer that sells old lettuce is willing to pay $1.50 a box. Past history says that tomorrow's demand for lettuce averages 250 boxes with a standard deviation of 34 boxes. Required: How many boxes of lettuce should the supermarket purchase tomorrow
Given Information:
Cost price = $4
Selling price = $10
Salvage value = $1.50
Average demand = μ = 250 boxes
Standard deviation = σ = 34 boxes
Required Information:
Number of lettuce boxes = ?
Answer:
The supermarket should purchase 268 boxes of lettuce
Step-by-step explanation:
The required number of lettuce boxes that supermarket should purchase is given by
Number of lettuce boxes = μ + (z*σ)
Where μ is the average demand of lettuce boxes, σ is the standard deviation, and z is the z-score which is given by
p = C_us/(C_us + C_os)
The z-score corresponding to probability p will be obtained.
The cost of under stocking is given by
C_us = Selling price - Cost price
C_us = $10 - $4
C_us = $6
The cost of over stocking is given by
C_os = Cost price - Salvage value
C_os = $4 - $1.50
C_os = $2.50
p = C_us/(C_us + C_os)
p = 6/(6 + 2.50)
p = 0.7058
p = 70.58%
The z-score corresponding to 70.58% probability is approximately 0.54
Number of lettuce boxes = μ + (z*σ)
Number of lettuce boxes = 250 + (0.54*34)
Number of lettuce boxes = 250 + (18.36)
Number of lettuce boxes = 268.36
Number of lettuce boxes ≈ 268
Therefore, the supermarket should purchase 268 boxes of lettuce.
How to use z-table?
Step 1:
In the z-table, find the probability you are looking for and note down the two-digit number of the given row. (e.g 0.5, 2.2, 0.5 etc.)
Step 2:
Then look up at the top of z-table and note down the value in the column for the remaining decimal point in the range of 0.00 to 0.09.
Step 3:
Finally, add the numbers obtained from step 1 and step 2.
Arionna claims that since there are 3 feet in a yard, there are 9 cubic feet in a cubic yard. Which statement about her claim is true?
a.)Arionna is correct because there are 3 feet across the length of a cubic yard and 3 feet across the depth of a cubic yard. 3 times 3 = 9
b.)Arionna is correct because there are 3 feet in a yard and there are 3 dimensions in a cubic yard: length, depth, and height. 3 times 3 = 9
c.)Arionna is incorrect. There are only 3 cubic feet in a cubic yard because there are 3 feet in a yard, and the proportion will remain constant.
d.) Arionna is incorrect. There are 27 cubic feet in a cubic yard because a cubic yard is a prism with dimensions 3 ft Times 3 ft Times 3 ft. A prism with those dimensions will take 27 cubes to fill it if each cube is a unit cube of 1 ft.
Answer:
d.) Arionna is incorrect. There are 27 cubic feet in a cubic yard because a cubic yard is a prism with dimensions 3 ft times 3 ft times 3 ft. A prism with those dimensions will take 27 cubes to fill it, if each cube is a unit cube of 1 ft³.
Step-by-step explanation:
There are (3 ft)(3 ft) = 9 ft² in one square yard. To find the volume of a cubic yard, you need to multiply that by 3 ft again: (9 ft²)(3 ft) = 27 ft³.
_____
Additional comment
For many problems involving units, I like to keep the units with the numbers. That helps ensure the math is done correctly. In this problem, simply multiplying ft by ft gives ft^2, not ft^3, so you know right away that you haven't computed volume correctly.

Answer:

Step-by-step explanation:
In similar polygons, every side of one polygon is a certain number of times bigger than the corresponding side of the other polygon. This number is the scale factor. Since the perimeter of each polygon is the sum of the lengths of the sides of that polygon, the perimeters also have the same scale factor that the sides do.
For example, if a triangle has 3 sides measuring 5 cm each and a similar triangle has 3 sides measuring 10 cm each, you see that each side of the second triangle is 2 times the length of the corresponding side of the first triangle. The scale factor from the smaller triangle to the larger triangle is 2. Now look at the perimeters. Since 5 + 5 + 5 = 15 and 10 + 10 + 10 = 30, the perimeters are 15 cm and 30 cm, and again, the perimeter of the second triangle is the same 2 times bigger than the perimeter of the first triangle.
Now look at your problem.
The perimeter of the smaller flag to the right is 16.
We see a side on the larger flag is 15, but we don't see the same side length on the smaller flag, so 15 does not help us.
Now we see that a side of the smaller flag measures 4 and the corresponding side of the larger flag measures 12. We divide the larger side length by the corresponding smaller side length to find the scale factor.
12/4 = 3
The scale factor from the smaller flag to the larger flag is 3. The perimeters also have the same scale factor of 3.
perimeter = 3 * 16 = 48
Answer: 48
Answer:
48
Step-by-step explanation:
Similar polygons have their sides in proportion, and we call the proportion between pairs of corresponding sides on two similar polygons the scale factor between them. We want to find the perimeter of the larger flag given the smaller one, and comparing the side with length 12 on the larger one with the side of length 4 on the smaller, we get a scale factor of 12 / 4 = 3.
This tells us that all the lengths on the larger flag are 3 times longer than the corresponding lengths on the smaller flag. What happens to the perimeter when we scale all of the lengths? Well, if every side gets multiplied by three, the sum of those sides will naturally be multiplied by 3, too.
Our large flag has a perimeter 3 times bigger than the smaller one, then, and 3 × 16 = 48.
Un lago de forma circular tiene una longitud de 157 metros. ¿Cual es la distancia del centro del lago a la orilla?
Answer:
25 meters
Step-by-step explanation:
in this case they give us the information about the lake and that length corresponds to the perimeter.
the perimeter of a circle has the following formula:
p = 2 * pi * r
then r equals:
r = p / pi * 2
replacing we have:
r = 157 / (2 * 3.14)
r = 25
which means that the radius of the lake is 25 meters

the perimeter of a rectangle is 20 units. The length of the rectangle is the distance from(-2,6) to (5,6) What is the width in units of the rectangles?
Answer:
3 units.
Step-by-step explanation:
We can calculate the length, since it only moves on the "x" axis, since on the "y" axis, it remains the same.
We know that between -2 to 5, there are 7 units. 2 + 5 = 7.
Therefore this would be the length.
We know that the perimeter is equal to:
p = 2 * w + 2 * l
P = 20
20 = 2 * w + 2 * 7
2 * w = 20 - 14
w = 6/2
w = 3
therefore, the width value is 3 units.

find the perimeter of a circle whose diameter is 7 cm
Find the perimeter of the circle is the same as finding the circumference of the circle.
Circumference Formula: C = 2πr
Divide the diameter by 2 to find the radius.
7 / 2 = 3.5
Solve using the given values.
C = 2(3.14)(3.5)
C = 2(10.99)
C = 21.98
Therefore, the circumference (perimeter) of the circle is 21.98cm²

Use the information in the illustration to find the distance from the boathouse to the cabin. Round your answer to the nearest yard.
Answer:
The distance from the boathouse to the cabin = 50 yd (nearest yard)
Step-by-step explanation:
The question is incomplete.
Question:
To find the distance from the
boathouse on shore to the cabin on the island, a surveyor measures from the boathouse to point X as shown. He then finds m∠X with an instrument called a transit. Use the surveyor’s
measurements to find the distance from the boathouse to the cabin.
Find attached the diagram of the question.
Solution:
Let the distance from the boathouse to the cabin = y
the distance from the boathouse to the point X = 30yard
Find attached the diagram for the solution.
From the diagram, the triangle is a right angled triangle
Opposite = y
Adjacent = 30yd
∠X = 59°
Using trigonometry (SohCahToa)
We would apply Toa since adjacent is given and we are looking for opposite
tan θ = opposite/adjacent
tan 59° = y/30
y = 30 tan 59
y = 30(1.6643)
y = 49.929
y = 50 yd (nearest yard)
The distance from the boathouse to the cabin = 50 yd (nearest yard)
