Victor sold cupcakes and cookies yesterday. Each cupcake sold for $2.25 and each cookie sold for $0.50. At the end of the
day, Victor had sold $95.25 worth of cookies and cupcakes. If he sold 68 cupcakes and cookies combined, how many
cupcakes were sold and how many cookies were sold?
answer:number of cupcakes sold is 13 Number of cookies sold is 27
Step-by-step explanation:
Let x represent the number of cupcakes that Victor sold. Let y represent the number of cookies that Jane sold. Each cupcake sold for $2.25 and each cookie sold for $0.50. At the end of the day, This mean Victor had 2.25x 0.5y = 42.75 - - - - - - - - - -1she sold 40 cupcakes and cookies combined, it means thatx y = 40Substituting x = 40 - y into equation 1, it becomes2.25(40 - y) 0.5y = 42.7590 - 2.25y 0.5y = 42.75- 2.25y 0.5y = 42.75 - 90- 1.75y = - 47.25y = - 47.35/-1.75y = 27x = 40 - yx = 40-27 = 13
An equation is formed when two equal expressions. The number of cupcakes that Victor sold is 35, while the number of cookies that Victor sold is 33.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the number of cupcakes sold be represented by x, while the number of cookies sold is represented by y.
Now, the total number of cupcakes and cookies sold combined is equal to 68. Therefore, the equation can be written as
x + y = 68
x = 68 - y
Also, Each cupcake sold for $2.25 and each cookie sold for $0.50. And the total sale that Victor made is of $95.25. Therefore, the equation can be written as,
2.25x + 0.50y = 95.25
2.25(68 - y) + 0.5y = 95.25
153 - 2.25y + 0.5y = 95.25
-2.25y + 0.5y = 95.25 - 153
1.75y = 57.75
y = 33
Now, substitute the value of x in the first equation.
x + y = 68
x + 33 = 68
x = 35
Hence, the number of cupcakes that Victor sold is 35, while the number of cookies that Victor sold is 33.

Answer:
the line plot in the bottom right corner
Step-by-step explanation:
Answer:
D is the correct graph.
Step-by-step explanation:
First you put the entries in ascending order, because that's how the line plot needs to be ordered.
1/4, 3/8, 1/2, 3/4, 7/8, 1, 1 1/4
So right there, you can rule out A.
You can rule out C because 1/4 does not occur 5 times in the data set.
B is incorrect because 3/8 isn't on the line plot at all.

When Larry tried to teach his dog Allegra to speak, he gave him 1 sausage - and he barked once. When he
gave him 2 sausages, he barked twice. Then he gave him 3 sausages, and he barked three times.
Larry predicted that Allegra would bark four times if he gave him 4 sausages.
What type of reasoning did Larry use to make his prediction?
A. Deductive reasoning
B. Inductive reasoning
C. Indirect reasoning
D. Circular reasoning
In case of : Allegra barking n = 4 times, when given 4 sausages - Inductive Logic is used.
Given : Allegra barks once & twice & thrice, when Larry gives him 1 & 2 sausages respectively.
So, later he assumes that he would bark 4 times, if given four sausages
Deductive Reasoning is when conclusion related to particular is drawn, based on general universal. Eg : All men are mortal, Ram is a man. Ram is mortal. Inductive Reasoning is when a generalised conclusion is drawn, based on specific case. Eg : Law of gravity based on apple falling. Allegra's case of barking n times for n sausages (1, 2,3 ...) is further generalised for other positive numbers & hence 4. Indirect Reasoning relates two events. If A is true leads to B is true, then B is false implies A has also been false. Circular Reasoning is a logical fallacy of beginning with an already assumed true statement.To learn more, refer https://brainly.com/question/2848937?referrer=searchResults
Determine the equation of the circle graphed below.
Answer:
(x + 5)² + (y - 1)² = 4
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (- 5, 1) and r = 2, then
(x - (- 5))² + (y - 1)² = 2² , that is
(x + 5)² + (y - 1)² = 4
Answer:
Step-by-step explanation:
hello :
hello:
note : an equatin for the circle is : (x-a)²+(y-b)²=r²
when the center is the point : C(a , b) and the radius r
use this graph : given two points in this circle A(-3,1) and B(-7,1)
1) AB/2 = r = 4/2 = 2
2) the midipoint for the segment AB is the center C
a = (-3-7)/2 and b = (1+1)/2
a= -5 and b= 1 so : C(-5 , 1)

Answer:
135degrees
Step-by-step explanation:
Find the diagram attached.
Note that in a cyclic quadrilateral, the sum of the opposite side of the quadrilateral is 180degrres.
According to the diagram shown:
<D+<I = 180
<D+45 = 180
Subtract 45 from both sides
<D+45-45 = 180-45
<D = 180-45
<D= 135°
Hence the measure of <D is 135degrees

its d cause there is actually 208 nickles and if u ad 8 more it gives u 216.
Answer: D.
Step-by-step explanation:
52x4=208
Since we know she has 4 times as many nickels as dimes(52), we just have to multiply 52x4 to get 208 nickels
208+8=216
We know that she has 8 more quarters than nickels(208) so we have to add 8 to 208 to get 216 quarters

Create an equation that models the total number of calories Jonathan consumes,y,based on number of biscuits he eats,x,and the 6 packages of pemmican
An equation that models the considered calorie consumption by Jonathan is y = mx + 6k, where m is the number of calorie per buiscuit, and k is the number of calorie per package of pemmican.
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
We're specified that:
x = number of buiscuits Jonathan eastsy = number of calories Jonathan consumes6 = number of packages of pemmican that jonathan consumes.Let we take:
m = number of calories per buiscuit that Jonathan eats.
Then, for x buiscuits, it would be [tex]m \times x[/tex] calories, or in short [tex]mx[/tex] calories.
Let k = number of calories per package of pemmican, then:
for 6 packages of pemmican, it would be [tex]6 \times k[/tex] calories, or in short [tex]6k[/tex] calories.
Thus, total calories Jonathan consumes = y = calories from x buiscuits + calories from 6 packages of pemmican.
or, we get:
[tex]y = mx + 6k[/tex]
Thus, an equation that models the considered calorie consumption by Jonathan is y = mx + 6k, where m is the number of calorie per buiscuit, and k is the number of calorie per package of pemmican.

g(x) =(1/4 x)²
g(x) = 4x² will be the equation of the parabola.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
Given, two parabolas f(x) and g(x),
From the general equation of the parabola,
y = a(x – h)² + k or x = a(y – k)² +h.
Here (h, k) denotes the vertex.
As we can see in our case, the vertex is (0, 0)
Thus, the equation of the parabola will be
y = ax²
Since the given parabola passes through the point (1, 4)
Substitute the values,
4 = a(1)²
a = 4
therefore, the equation of the parabola g(x) will be,
g(x) = 4x²
