Aunt Gwen is pricing cakes for a baby shower she is throwing. She wants one large cake shaped like a duckling and also some cupcakes in pastel colors. Hillsboro Bakery charges $4 for each cupcake, plus $28 for the large cake. Carson's Sweet Shoppe charges $55 for the large cake and $1 for each cupcake. If Aunt Gwen orders a certain number of cupcakes, the cost will be the same at either bakery. How many cupcakes would that include? What would the total cost be?
If Aunt Gwen orders ___ cupcakes, it will cost $ ___ at either shop.
Answer:
9 cupcakes and 64$
Step-by-step explanation:
try the math
So first, set up an equation for each shop, for the first one you can write 4x+28 (since it is 4 dollars for each cupcake and 28 dollars for the cake) and for the second shop you can write 55+x ( 55 dollars for cake and a dollar for each cupcake.) now you can set the 2 equations equal to each other because they want the number for cupcakes where the price will be equal. So 4x+28=55+x and then solve. I don’t want to completely tell you the answer but if you are stuck, you can tell me and I will gladly help.
A pair of sneakers cost $75. This is $15 less than the cost of a pair of jeans. Write an equation that someone could use to find the amount of money that the jeans cost.
15+75=J.
So the jeans should be $90
Answer-
add 15 from 75 then that is it
75+15=90
Bradley dropped a ball from a roof 16feet high. Each time the ball hits the ground it bounces 3/5 the previous height. Find the height ball will bounce after hitting the ground the fourth time
Answer: 2.0736 ft
Step-by-step explanation:
Bounce 1: 16*3/5=9.6
Bounce 2: 9.6*3/5=5.76
Bounce 3: 5.76*3/5=3.456
Bounce 4: 3.456*3/5=2.0736
Answer:
The ball will bounce to 2.07 feet after 4th drop.
Step-by-step explanation:
Bradley dropped a ball from a roof 16 feet high. So, its the initial height.
Each time the ball hits the ground it bounces 3/5 the previous height.
Means after 1st drop, the ball will again rise to [tex]\frac{3}{5}\times16= 9.6[/tex] feet.
Similarly after 2nd drop, it will bounce to [tex]\frac{3}{5}\times9.6=5.76[/tex]
After 3rd drop, it will bounce to [tex]\frac{3}{5}\times5.76=3.456[/tex] feet
After 4th drop, it will bounce to [tex]\frac{3}{5}\times3.456=2.0736[/tex] feet
Hence, the ball will bounce to 2.07 feet after 4th drop.
Simplify 8r+(-4r)+3 and then solve if r=5
Simplify= 4r+3
Because 8r plus -4r which is 4r and then 3 can’t be simplified so u keep it the same
Then the answer if r=5 is 23
Because the equation looks like 4(5)+3
5 times 4 is 20 plus 3 is 23
Final answer:
The expression 8r+(-4r)+3 simplifies to 4r + 3. Substituting r=5 into the simplified expression gives you 4(5) + 3, which equals 23.
Explanation:
To simplify the expression 8r+(-4r)+3, you combine the like terms which are 8r and -4r. They are like terms because they both contain the variable r.
Simplifying the like terms:
8r + (-4r) = 8r - 4r = 4r
So now the expression simplifies to 4r + 3. To solve for r = 5, you substitute the value of r into the simplified expression:
4r + 3 becomes 4(5) + 3,
20 + 3 = 23.
Therefore, when r = 5, the simplified expression evaluates to 23.
A jacket was $50 and is now on sale for $35. What is the percent change in the cost?
from 50 to 35 is 15, so it went down by $15.
if we take 50 to be the 100%, what is 15 off of it in percentage?
[tex]\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 50&100\\ 15&x \end{array}\implies \cfrac{50}{15}=\cfrac{100}{x}\implies \cfrac{10}{3}=\cfrac{100}{x}\implies 10x=300 \\\\\\ x=\cfrac{300}{10}\implies x=30[/tex]
Answer:
-30%
Step-by-step explanation:
The decrease in price was $15.
Divide $15 by $50, obtaining 0.30, which in turn is mult. by 100%.
The percentage change, from $50 to $35, was -30%.

2. Find the area and circumference of the circle to the right.
16.6 m
Answer:
AREA:
[tex]A=216.42m^2[/tex]
CIRCUMFERENCE:
[tex]C=52.15m[/tex]
Step-by-step explanation:
The formula that is used to calculate the area of a circle is:
[tex]A=\pi r^2[/tex]
Where "r" is the radius of the circle.
The formula for calculate the circumference of a circle is:
[tex]C=2\pi r[/tex]
Where "r" is the radius of the circle.
Then, you need to find the radius. This is:
[tex]r=\frac{16.6m}{2}=8.3m[/tex]
Substituting the radius, you get that the area and the circumference are:
AREA:
[tex]A=\pi (8.3m)^2=216.42m^2[/tex]
CIRCUMFERENCE:
[tex]C=2\pi (8.3m)=52.15m[/tex]
Answer with step-by-step explanation:
We are given a circle which is divided into two halves and has a diameter of 16.6 meter. We are to find the area and circumference of the circle to the right.
It means that our radius will be the half of the given diameter.
Radius = 16.6/2 = 8.3 m
Area = [tex]\pi r^2[/tex] = [tex]\frac{\pi \times (8.3)^2}{2}[/tex] = 216.4 m^2
Circumference = [tex]2 \pi r[/tex] = [tex]2 \times \pi \times 8.3[/tex] = 52.2 m
PLEASE HELP & SHOW WORK , ITS URGENT
it’s appreciated <3 !!
see if u understand the answer
Answer:
C
Step-by-step explanation:
The circumference (C) of a circle is calculated using
C= 2πr ← r is the radius and has to be found
Given C = 20π , then
2πr = 20π ( divide both sides by 2π )
r = [tex]\frac{20\pi }{2\pi }[/tex] = 10
The area (A) of a circle is calculated using the formula
A = πr² = π × 10² = 100π m² → C
Use the properties of exponents to solve for the each variable.

The following set of coordinates represent which figure?(7,10) (4,7) (6,5) (9,8)
Answer: i think a diamond
Step-by-step explanation:
Let's assume these are the vertices in order and calculated the squared lengths of the sides. Let's calculate the vector for each side, which is the difference of the endpoints:
(7,10) - (4,7) = (3, 3)
(4,7) - (6,5) =(-2, 2)
(6,5) - (9,8) = (-3, -3)
(9,8) - (7,10) = (2, -2)
We see the pattern: (3,3) = -(-3,-3) and (-2,2) = -(2,-2)
We have two pairs of opposite vectors so we have a parallelogram.
Let's check the dot product of adjacent sides:
(3,3) . (-2, 2) = 3(-2) + 3(2) = 0
Zero dot product, we have perpendicularity. A parallelogram with one right angle is a
Answer: Rectangle
The adjacent sides are clearly not congruent so it's not a square

If the circle graph below represents the responses from 350 people, how many people chose silver as their favorite car color?
Black-25%
White-10%
Silver-10%
Yellow-5%
Red-50%
350
10
35
100
For this you have to make two proportions that are [tex]\frac{part}{whole}[/tex] and set them equal to each other.
The first proportion represents the percent of people who like silver as their favorite car color
Since this is a circle graph the whole will always be 100 because percents are always taken out of 100
The part would be 10 because only 10% out of the 100% like silver
The second proportion is the people that represent the response.
350 would be the whole because that is the total amount of people surveyed
The part is unknown and what you are solving for.
Here is how the proportion should look like:
[tex]\frac{10}{100} = \frac{x}{350}[/tex]
Cross multiply (If you don't know what this is look at the image below to see my work)
The cross multiplication will give you:
3500 = 100x
Isolate x by dividing 100 to both sides
3500/100 = 100x/100
35 = x
This means that 35 people out of the 350 surveyed like silver cars
Hope this helped!

Which function is increasing?
A. f(x) =(1/4) ^x
B. f(x) =(1/4) ^x
C. f(x) = 4^x
D. f(x) = (0.4)^x
Answer:
f(x) = 4^x
Step-by-step explanation:
In f(x) = (1/4)^x, 1/4 is equal to 0.25, which is less than 1, so its decreasing
In f(x) = 4^x, 4 is greater than 1, so its increasing
In f(x) = (0.4)^x, 0.4 is less than 1, so its decreasing
This is why f(x) = 4^x is the correct answer
I hope this helps!

If the circle graph represents the responses from 500 people, how many more people prefer burgers than cheeseburgers?
subs-10%
Tacos-10%
Chicken-10%
Pizza-30%
burger-25%
Cheeseburgers-15%
125
75
50
25
Answer:
50
Step-by-step explanation:
[tex]500 \div 100 \times 25 = 125[/tex]
[tex]500 \div 100 \times 15 = 75[/tex]
[tex]125 - 75 = 50[/tex]
50. From 500 people, 25% that prefer burger represent 125 people and 15% that prefer cheeseburger represent 75. This mean there are 50 more people that prefer burgers than cheeseburgers.
The key to solve this problem is by direct rule of three, we will place the 3 values (which we will call “a”, “b”, and “c”) and the unknown value that we want to figure out (“x”) to apply the formula:
a -----------> b
c -----------> x
[tex]x=\frac{b.c}{a}[/tex]
The circle graph represents the responses from 500 people in percentage.
To calculate the amount of people that prefer burgers:
If 100% ----------------> 500 people
25% ----------------> x
[tex]x=\frac{(500)(25)}{100}= 125[/tex] which means 125 people prefer burgers
To calculate the amount of people that prefer cheeseburgers:
If 100% ----------------> 500 people
15% ----------------> x
[tex]x=\frac{(500)(15)}{100}= 75[/tex] which means 75 people prefer cheeseburgers.
In order to know how many more people prefer burgers than cheeseburgers, let's apply the difference between people who prefer burgers and people who prefer cheeseburgers:
125 - 75 = 50 which mean 50 more people prefer burgers than cheeseburgers.

What is the range of the function g(x) = 3x2 - 6x + 3 when the domain is defined as the set of integers, x, such that 0<=x<=4? Show all work. I really need help y’all I have and f :(
Answer:
the domain of this function is [0, 27]
Step-by-step explanation:
One way of answering this question would be to make a table of x and y values. Your x-values would be [0, 4] (that is, all x values between 0 and 4, including end points.
x y = 3x² - 6x + 3
0 3
1 0
2 3
4 27
From this table, it appears highly likely that the smallest y value would be 0, at x = 1, and that the largest would be 27 at x = 4. Thus, the domain of this function is [0, 27].

What are the solutions for x when y is equal to 0 in the following quadratic
function?
y = x² + 10x – 24
OA) X= -4 or x = -6
OB) x = -6 or x = 4
OC) x = -2 or x = 12
OD) x = -12 or x = 2
O E) no real solutions
Answer:
D) x = -12 or x = 2
Step-by-step explanation:
The given quadratic equation is:
[tex]y=x^2+10x-24[/tex]
When y=0, we obtain:
[tex]x^2+10x-24=0[/tex]
We split the middle term with -2, 12 because their product is is -24 and their sum is 10.
[tex]x^2-2x+12x-24=0[/tex]
We factor by grouping to obtain:
[tex]x(x-2)+12(x-2)=0[/tex]
[tex](x-2)(x+12)=0[/tex]
Either [tex](x-2)=0[/tex] or [tex](x+12)=0[/tex]
Either [tex]x=2[/tex] or [tex]x=-12[/tex]
