Pizza Uno offers 2/3 of a small pizza for $3.50. Pizza Duo offers % of a small pizza for $4.20. How much does each charge for a whole small pizza?
Show your work and remember to answer the question.
PLSS ANSWER!!!! ILL GIVE BRAINLIEST!
Answers:
Pizza Uno = $5.25Pizza Duo = $5.60Those are the costs for a whole small pizza.
==========================================================
Explanation:
Let
x = cost of whole small pizza from Pizza Unoy = cost of whole small pizza from Pizza Duox and y are some dollar amount, so they cannot be negative numbers. It also doesn't make sense to have them be 0 either. So we'll make them positive.
2/3 of x is equal to 3.50 as the first sentence mentions. This forms the equation (2/3)*x = 3.50
Multiply both sides by the reciprocal of 2/3 to isolate x
(2/3)*x = 3.50
(3/2)*(2/3)*x = (3/2)*3.50
x = 5.25
Pizza Uno charges $5.25 for a whole small pizza.
----------------------------
Pizza Duo charges $4.20 for 3/4 of a small pizza, meaning the equation we need to solve is
(3/4)y = 4.20
We'll use the same idea as the last equation to get...
(3/4)y = 4.20
(4/3)*(3/4)y = (4/3)*4.20
y = 5.60
Pizza Duo charges $5.60 for a whole small pizza.
Pizza Uno is the better deal (assuming both pizzas taste the same or you don't have a preference for either). You would save $5.60 - $5.25 = $0.35 = 35 cents.

Answer:
[tex]BD = 4[/tex]
[tex]BC =4\sqrt 3[/tex]
Step-by-step explanation:
Given
The attached triangle
Required
Find BD and BC
Solving BD
Considering angle at D, we have:
[tex]\cos(D) = \frac{Adjacent}{Hypotenuse}[/tex]
[tex]\cos(60) = \frac{BD}{8}[/tex]
Solve for BD
[tex]BD = 8 * \cos(60)[/tex]
[tex]\cos(60) = 0.5[/tex] So:
[tex]BD = 8 * 0.5[/tex]
[tex]BD = 4[/tex]
To solve for BC, we make use of Pythagoras theorem
[tex]CD^2 = BC^2 + BD^2[/tex]
This gives
[tex]8^2 = BC^2 + 4^2[/tex]
[tex]64 = BC^2 + 16[/tex]
Collect like terms
[tex]BC^2 =64-16[/tex]
[tex]BC^2 =48[/tex]
Take square roots
[tex]BC =\sqrt{48[/tex]
Expand
[tex]BC =\sqrt{16*3[/tex]
Split
[tex]BC =\sqrt{16}*\sqrt 3[/tex]
[tex]BC =4\sqrt 3[/tex]
A landscape designer has to construct a rectangular flower bed with a perimeter of 100 feet and the maximum possible area. What is the area of the flower bed
9514 1404 393
Answer:
625 square feet
Step-by-step explanation:
The greatest area of a polygon with a given perimeter is that of a regular polygon. A regular rectangle is one that has all sides the same length -- a square. The side length of a square with 100 ft perimeter is 25 ft. The area of a square with such a side length is
A = (25 ft)² = 625 ft²
The maximum possible area is 625 ft².
__
In the attached, x is the length of one side. The area versus side length is plotted. The maximum is seen to be 625 ft² for a side length of 25 ft.
[tex]3^{x} = 4[/tex]
4^{y} = 12
estimate xy
9514 1404 393
Answer:
xy ≈ 2.3
Step-by-step explanation:
Logarithms can be used to find x and y.
3^x = 4
x·log(3) = log(4)
x = log(4)/log(3)
__
4^y = 12
y = log(12)/log(4)
__
Then xy is ...
xy = log(4)/log(3) × log(12)/log(4) = log(12)/log(3)
xy ≈ 1.079/0.477
xy ≈ 2.26
Only got two days this is last resort wouldn’t mind help
Answer:
Option C.
Step-by-step explanation:
If we have two functions:
f(x) and g(x)
the product is given by:
(f*g)(x) = f(x)*g(x)
So, if here we have
f(x) = √(3*x)
g(x) = √(48*x)
And remembering that the square root is distributive, so:
√a*√b = √(a*b)
We can write:
(f*g)(x) = f(x)*g(x) = √(3*x)*√(48*x) = √(3*x*48*x)
= √(3*48*x*x) = √(144*x^2) = √(144)*√(x^2)
And here we can use that:
12*12 = 144, then √144 = 12
and
x*x = x^2, then √x^2 = x
So:
√(144)*√(x^2) = 12*x
Then the correct option is C.

O A. f(x) is shifted down 2 units to g(x).
O B. f(x) is shifted up 2 units to g(x).
O c. f(x) is shifted up 5 units to g(x).
OD. (x) is shifted down units to g(x)
The transformation of f(x) to g(x) is f(x) is shifted down 2 units to g(x).
The correct option is (A)
What if transformation of a function?
Transformations of functions mean transforming the function from one form to another. Transformation of functions is a unique way of changing the formula of a function minimally and playing around with the graph.
The given function f(x)= sin x
In the graph there is vertical shift from f(x) to g(x)
We know, the vertical shift depends on the value of k
When k>0, the vertical shift is described as
g(x)=f(x)+k- The graph is shifted up k units.g(x)=f(x)−k - The graph is shifted down k units.If we closely look at the graph the vertical distance in negative y-axis,
the distance between line f(x) and g(x) is from 0 to -2.
So, there is shifting of -2 units means there is downward shifting.
i.e., k=2
Hence, f(x) is shifted down 2 units to g(x).

Which expression represents the length of the hypotenuse, c, of the triangle below?
Pleaseeeeee I neeed helpppp
Answer:
C) [tex]c=\sqrt{a^{2} +b^{2} }[/tex]
Step-by-step explanation:
The Pythagorean Theorem states that for a right triangle, the relationship between its three sides is [tex]a^{2} +b^{2} =c^{2}[/tex] where [tex]a[/tex] and [tex]b[/tex] are side lengths and [tex]c[/tex] is the length of the hypotenuse.

The distribution of the amount of money in savings accounts for Florida State students has an average of 1,200 dollars and a standard deviation of 900 dollars. Suppose that we take a random sample of 10 Florida State students and ask them how much they have in their savings account. The sampling distribution of the sample mean amount of money in a savings account is
Answer:
By the Central Limit Theorem, the sampling distribution of the sample mean amount of money in a savings account is approximately normal with mean of 1,200 dollars and standard deviation of 284.6 dollars.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Average of 1,200 dollars and a standard deviation of 900 dollars.
This means that [tex]\mu = 1200, \sigma = 900[/tex]
Sample of 10.
This means that [tex]n = 10, s = \frac{900}{\sqrt{10}} = 284.6[/tex]
The sampling distribution of the sample mean amount of money in a savings account is
By the Central Limit Theorem, approximately normal with mean of 1,200 dollars and standard deviation of 284.6 dollars.
The sampling distribution of the sample mean amount of money in a savings account is mean of 1,200 and standard deviation of 284.6 dollars.
Calculation of mean & standard deviation:Since the distribution of the amount of money in savings accounts for Florida State students has an average of 1,200 dollars and a standard deviation of 900 dollars. And, a random sample of 10.
So here the mean should be $1,200
And, the standard deviation should be

A spherical exercise ball has a maximum diameter of 30 inches when filled with air. The ball was completely empty at the start, and an electric air pump is filling it with air at the rate of 1600 cubic Inches per minute. The formula for the volume of a sphere is 4pi (r^3/3)
Part A Enter an equation for the amount of air still needed to fill the ball to its maximum volume, y, with respect to the number of minutes the pump has been pumping air into the ball, X.
Part B Enter the total amount of air, in cubic inches, still needed to fill the ball after the pump has been running for 4 minutes.
Part C Enter the estimated number of minutes it takes to pump up the ball to its maximum volume.
Answer:
A) A(t) = 4500*π - 1600*t
B) A(4) = 7730 in³
C) t = 8,8 sec
Step-by-step explanation:
The volume of the sphere is:
d max = 30 r max = 15 in
V(s) = (4/3)*π*r³ V(s) = (4/3)*π* (15)³
V(s) = 4500*π
A) Amount of air needed to fill the ball A(t)
A(t) = Total max. volume of the sphere - rate of flux of air * time
A(t) = 4500*π - 1600*t in³
B) After 4 minutes
A(4) = 4500*π - 6400
A(4) = 14130 - 6400
A(4) = 7730 in³
C) A(t) = 4500*π - 1600*t
when A(t) = 0 the ball got its maximum volume then:
4500*π - 1600*t = 0
t = 14130/1600
t = 8,8 sec
Compare the temperature change for the two masses of cold water (50 grams and 100 grams) when the same amount of hot water was added. What do you discover?
Answer:
Step-by-step explanation:
All other things being equal (and there are a lot of other things) the 50 gram mass will show a larger temperature
increase than the 100 gram mass.
Why?
The formula is the same from both masses of water (50 grams and 100 grams)
The amount of heat added is the same. (Instead of using hot water, we'll a hot plate on a very low temperature but above what they are now.).
We'll leave it on until we see a rise in temperature delta(t1) = 10 degrees
mc delta(t) = m1 * c * delta(t1)
m = 100
m1 = 50 grams.
c is going to be divided out
we'll solve for the ratio of delta(t) / delta(t1)
100 * delta(t) = 50 (delta(t1)
100 * delta(t) = 50*10
delta(t) = 50*10/100
delta(t) = 5 degrees.
Though this may look rather convoluted, the result is telling us is that delta(t1) for the 50 gram mass is twice as big as as for the 100 gram mass.
The 100 gram mass only rises 5 degrees.
The 50 gram mass rises 10 degrees.
Answer:
50 gram mass will show a larger temperature
increase than the 100 gram mass.
Step-by-step explanation:
50 gms water at 20 ⁰ C and 50 gms of water at 40⁰ C are mixed. Since the masses of the liquid at different temperatures are same, the answer is very easy and simple : average of 20⁰C and 40⁰C. that is: 30⁰C.
