The cost of a pizza varies directly as the square of its radius. If a pizza with a 6 inch radius costs Php 8.00, how much should a pizza with an 11 inch radius cost?
Answer:
An 11 inch radius pizza costs Php 14.63!
Step-by-step explanation:
We have to find the average cost for each inch radius of pizza!
8/6 = 1 1/3
The average cost is Php 1.33
Now we multiply that by 11
1.33 * 11 = 14.63
An 11 inch radius pizza costs Php 14.63
A pizza with a 6 inch radius costs Php 8.00.
A pizza with 11" radius costs Php 26.88.
Let:-
k = constant
c = cost of a pizza
r = radius of pizza
The cost of a pizza varies directly as the square of its radius.
[tex]c[/tex] ∝ [tex]r^{2}[/tex]
[tex]c=kr^{2}[/tex]
Where: c = 8, r = 6
[tex]8=k(6)^{2} \\k=\frac{8}{36} \\\\k=\frac{2}{9}[/tex]
When r = 11 inch
[tex]c=kr^{2}\\c=(\frac{2}{9})(11)^{2}\\c=26.88[/tex]
Therefore, A pizza with 11" radius costs Php 26.88.

On Saturday, Kylee’s volleyball team will be having a family picnic. Hot dogs are sold at the local store with 15 hot dogs in a package. Hot dog buns, however, are only sold in packages of 6 hot dog buns. Kylee’s team wants to buy the exact same number of packages for hot dogs as hot dog buns.
What is the least number of packages of hot dogs and hot dog buns that Kylee’s team should buy to have exactly the same number of hot dogs as hot dog buns? If a package of hot dogs cost $2.98 and a package of hot dog buns cost $2.16, what was the total expense?
Answer:
Kylee's family need at least 2 packages of hot dogs and 5 packages of hot dog buns to have exactly the same number of hot dogs and hot dog buns.
Total expense is $16.76
Step-by-step explanation:
The lowest common multiple of 6 and 15 is 30.
Two packages of hot dogs contain 30 hotdogs.
Five packages of hot dog buns contain 30 hotdog buns.
If one package of hotdog costs $2.98, two packages would cost $2.98 × 2 = $5.96
If one package of hot dog buns costs $2.16, five packages would cost $2.16 × 5 = $10.8
$5.96 + $10.8 = $16.76
the graph shows the functions
Answer:
x = -1, y = -1 and x = [tex]\frac{1}{2}[/tex] , y = 2
Step-by-step explanation:
To find the solution of the system of equations from their graphs find the intersection points between the two graphs, they are the solution of the system
In the given figure
∵ f(x) = 2x + 1
∴ It is represented graphically by a line
∵ g(x) = [tex]\frac{1}{x}[/tex]
∴ It is represented graphically by two curved lines on 1st and 3rd
quadrants
∵ The solution of the system of the equations is the points of
the intersection of the two graphs
∵ The two graphs intersected at points (-1, -1) and ([tex]\frac{1}{2}[/tex] , 2)
∴ The solution of the system of the equations is (-1, -1) and ([tex]\frac{1}{2}[/tex] , 2)
∴ x = -1, y = -1 and x = [tex]\frac{1}{2}[/tex] , y = 2

Answer: B) 38
Step-by-step explanation:
1) [tex]x+(x+6)+(3x-16)=180[/tex] (sum of angles in triangle)
2) [tex]5x-10=180[/tex] (Algebra)
3) [tex]5x=190[/tex]
4) x= 38 degrees
Answer: x = 38
Step-by-step explanation:
1) Add 3x - 16 and x + 6 and x together. You get 5x - 10.
2) All sides of a triangle equals 180 degrees, so that means 5x - 10 = 180.
3) Add 10 to both sides, 5x = 190.
4) 190/5 = 38
5) 38 is your answer.

Answer:
x = y = 36°
Step-by-step explanation:
Inscribed angles subtended on the same arc are congruent.
The measure of the inscribed angle is half the measure of its intercepted arc, thus

Find the value of xxx in the triangle shown below.
Answer:
x = 50 °
Step-by-step explanation:
This is an isosceles triangle, and this is apparent because there are two sides which are of the same length (7). This means that the angles opposite to it would also be same (this is one of the properties of an isosceles triangle).
So the other angle would also be x. And the sum of all angles in a triangle would add up to 180.
x + x + 80 = 180
2x = 100
x = 50 °

Write an equivalent expression
-3 + 2/3y - 4 - 1/3y
Answer:
join the y-related together and the others together
ie -7+1/3y
thats the shortest form one can drill down to, so that should be the answer
Step-by-step explanation:
To write an equivalent expression, we need to simplify the given expression by combining like terms. Like terms are terms that have the same variable and exponent. We can use the distributive property to remove parentheses or other grouping signs to then combine like terms.
The given expression is -3 + 2/3y - 4 - 1/3y. We can see that there are no parentheses or grouping signs, so we can skip that step. We can also see that there are two like terms: 2/3y and -1/3y. We can combine them by adding their coefficients: 2/3 + (-1/3) = 1/3. So, we get:
-3 + 2/3y - 4 - 1/3y = -3 - 4 + (2/3 - 1/3)y = -7 + (1/3)y
This is the simplified expression that is equivalent to the given expression.

Find the surface area of the square pyramid
Answer:
The surface area of the square pyramid is 40 units².
Step-by-step explanation:
As we know that the total surface area of a square pyramid can be obtained by identifying the length 'b' of its base and its slant height 's' by using the formula:
[tex]A=2bs+b^2[/tex]
From the figure, it is clear that
length of its base = 'b' = 4slant height = 's' = 3substituting the values in the formula
[tex]A=2bs+b^2[/tex]
[tex]A=2\left(4\right)\left(3\right)+\left(4\right)^2[/tex]
[tex]=2\left(4\right)\left(3\right)+16[/tex]
[tex]=40[/tex]
Therefore, the surface area of the square pyramid is 40 units².

Susan buys the items listed below at a grocery store. 2 packages of chicken priced at $12.56 per package 1 pound of broccoli priced at $1.98 per pound 2 1 gallon of milk priced at per $3.49 gallon There is no sales tax on the food she buys. Susan pays for the items and receives $0.80 in change. What amount of money does Susan use to pay for the items?
Answer: $30
Step-by-step explanation:
Your question isn't well written. Here's the complete question:
Susan buys the item listed below at a grocery store. 2 packages of chicken priced at $12.36 per package. 1/2 pound of broccoli priced at $1.98 per pound. 1gallon of milk priced at $3.49 per gallon. There is no sales tax on the food she buys. Susan pays for the items and recevies $0.80 in change. What amount of money does Susan use to pay for the items?
2 packages of chicken priced at $12.36 per package will cost:
= 2 × $12.36
= $24.72
1/2 pound of broccoli priced at $1.98 per pound will cost:
= 1/2 × $1.98
= $0.99
1 gallon of milk priced at per $3.49 per gallon will be:
= 1 × $3.49
= $3.49
We are then told that Susan pays for the items and receives $0.80 in change. The amount of money does Susan use to pay for the item will be:
= $24.72 + $0.99 + $3.49 + $0.80
= $30

Answer: -53, 53
Step-by-step explanation:
It’s asking for the slope first, so let’s find it:
First, let’s determine our coordinates.
We have (1, 930) and (6, 655).
The slope equation is [tex]\frac{y_1 - y_2}{x_1 - x_2}[/tex], so let our (1, 930) be our x_1 and y_1, and (6, 655) be our x_2 and y_2.
So, we have,
= [tex]\frac{655-930}{6-1}[/tex]
This simplifies to
= [tex]\frac{-265}{5}[/tex]
which is -53.
Therefore, the slope is -53, so the balance decrease by $53 each month.

y = -2 x
y = 2 x - 2
y = x - 2
y = 3 x - 3
Answer:
[tex]y=2x-2[/tex] is the required equation.
Therefore, the second option is true.
Step-by-step explanation:
We know that the slope-intercept form of the line equation of a linear function is given by
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
Taking two points (0, -2) and (1, 0) from the table to determine the slope using the formula
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:-2\right),\:\left(x_2,\:y_2\right)=\left(1,\:0\right)[/tex]
[tex]m=\frac{0-\left(-2\right)}{1-0}[/tex]
[tex]m=2[/tex]
substituting the point (0, -2) and the slope m=2 in the slope-intercept form to determine the y-intercept i.e. 'b'.
[tex]y=mx+b[/tex]
[tex]-2 = 2(0)+b[/tex]
[tex]-2=0+b[/tex]
[tex]b=-2[/tex]
Now, substituting the values of m=2 and b=-2 in the slope-intercept form to determine the equation of a linear function
[tex]y=mx+b[/tex]
[tex]y=2x+(-2)[/tex]
[tex]y=2x-2[/tex]
Thus, [tex]y=2x-2[/tex] is the required equation.
Therefore, the second option is true.
