Answer:
Part a y=10.99+1.25x
Part B 14.74
Answer:
Part A) 10.99 + x = y
Part B) 14.74$
Step-by-step explanation:
In part A, you add the number of toppings to the pizza. Making the expression: Pizza Cost + Topping = Total Amount.
In part B, you do 1.25*3 = 3.75 (Cost of 3 toppings) + 10.99 (Cost of the pizza) = 14.74$
Hope this helps! 'v'
Toni and Makayla are working on a craft project. Makayla has 3 yards of ribbon and Toni has 4 yards of ribbon. They cut all the ribbon into pieces that are 1/4 yard long. How many pieces of ribbon do they have?
Answer:
Toni and Makayla have 16 and 12 pieces of ribbon respectively, 28 in total
Step-by-step explanation:
Fractions
Toni has 4 yards of ribbon and Makayla has 3 yards of ribbon.
The ribbon is cut into pieces of 1/4 yards each.
This means that Toni has:
[tex]\displaystyle \frac{4}{\frac{1}{4}}=16[/tex]
pieces of ribbon and Makayla has:
[tex]\displaystyle \frac{3}{\frac{1}{4}}=12[/tex]
pieces of ribbon.
Toni and Makayla have 16 and 12 pieces of ribbon respectively, 28 in total

Step-by-step explanation:
The price of a laptop changed from $350.00 to $550.00. What is the percent change in the cost of the laptop? 200% increase 200% decrease 57.14% increase 57.14% decrease
Answer:
57.14% increase
Step-by-step explanation:
$350÷$200(amount of increase) = 0.5714
0.5714×100= 57.14%
find the measure of angle A:
find the measure of angle B:
Answer:
Hi...
2x+4+2x-9+x=180
5x-5=180
5x=185
X=185/5=37....so
A=2*37-9=65
B=2*37-4=70
Answer: see explanation
Step-by-step explanation:
Sum of all angles in a triangle is 180
So add all those angles together equals 180.
2x + 4 + 2x -9 + x = 180
Combine like terms.
5x -5 = 180
5x = 185
X = 37
Now plug x in for the angles
A = 2x -9
A = 2(37) - 9
A= 74 - 9 = 65
B = 2x + 4
B = 2(37) + 4
B = 74 + 4
B = 78
A 25 ft ladder leans against a building. The ladder’s base is 13.5 feet from the building. Find the angle of elevation, which the ladder makes with the ground.
Answer:
57.3°
Step-by-step explanation:
A 25 feet ladder leans against a building.
The ladder's base is 13.5 feet from the building.
The ladder, the wall of the building and the ground form a right-angled triangle of:
Hypotenuse = 25 feet
Base = 13.5 feet
We are to find the angle of elevation which the ladder makes with the ground (or rather the angle created by hypotenuse and base)
Let's say the angle = X°
According to a trigonometric equation;
cos X° = adjacent side ÷ hypotenuse = [tex]\frac{13.5}{25}[/tex] = 0.54
[tex]cos ^{-1} X[/tex] = 57.5=3° (Answer rounded up to nearest one decimal place).
∴ The angle of elevation = 57.3°

Candy is on sale for $0.75 each. You have a coupon for $0.25 off your total purchase.
Write a function rule for the cost of n pieces of candy.
A. C(n)= 0.25n-0.75
B. C(n)= 0.75n-0.25
C. C(n)= 1.0n
D. C(n)= 0.75n
Which one is it?
Answer: B. C(n)=0.75n-0.25
Hope these helped u :)
Step-by-step explanation:
Answer: I believe it's B because 1 candy bar=0.75 but there's a $0.25 percent off so I think 0.75n-0.25 would be the right answer

Answer:
x =1Step-by-step explanation:
Given the following DE = 4X-2
EF = 3x+2
FG 5x-3
GD = 2x+5
Since DE is parallel to GF, this means that the sides are equal hence;
4x - 2 = 5x - 3
4x - 5x = -3 + 2
-x = -1
x = 1
Hence the value of x is 1

Bacteria growth. A colony of bacteria is grown under ideal conditions in a laboratory so that the population increases exponentially with time. At the end of 3 h there are 10,000 bacteria. At the end of 5 h there are 40,000 bacteria. How many bacteria were present initially
Answer:
1250 bacteria
Step-by-step explanation:
The formula for Exponential Growth is given as:
P(t)= Poe^rt
Where
P(t) = Population after time t
Po = Initial Population
r = growth rate
t = time
Hence, solving for the above question , we have to find Po
Making Po the subject of the formula
Po = P(t)/e^rt
Step 1
Find the Exponential growth rate
At the end of 3 h there are 10,000 bacteria.
Hence:
Po = 10000/e^3r.... Equation 1
At the end of 5 h there are 40,000 bacteria.
Po = 40000/e^5r..... Equation 2
Equating both equations together,
10000/e^3r = 40000/e^5r
Hence:
e^5r/e^3r = 40000/10000
e^2r = 4
Take the In of both sides
In (e^2r) =In 4
2r= In 4
r = In 4/2
r = In 2
Step 2
Solve for Po(Initial Population)
Using Equation 2
Po = 40000/e^5r..... Equation 2
r = In2
Po = 40000/e^5 × In 2
Po = 40000/2⁵
Po = 1250 bacteria.
Therefore, they was 1250 bacteria initially
What is the x coordinate of the solution to the system of equations?
{ x- 5y =23
{ -2x - 6y =2
Answer:
The x coordinate of the solution to the system of equations is 8
Step-by-step explanation:
We need to find the x coordinate of the solution to the system of equations?
[tex]x- 5y =23\\-2x - 6y =2[/tex]
Let
[tex]x- 5y =23--eq(1)\\-2x - 6y =2--eq(2)[/tex]
Multiply equation 1 with 2 and add both equations
[tex]2x- 10y =46\\-2x - 6y =2\\-------\\-16y=48\\y=\frac{48}{-16}\\y=-3[/tex]
So, we get the value of y = -3
Now, for finding x, put value of y in equation 1
[tex]x- 5y =23Put\:y=-3\\x-5(-3)=23\\x+15=23\\x=23-15\\x=8[/tex]
So, we get x = 8
The solution set is (8,-3)
So, the x coordinate of the solution to the system of equations is 8

Report roben
Answer:
The missing value is 6!
Step-by-Step Explanation:
First, we know that there are 4 values in total, so we must multiply the mean, 7, by 4 to get the total sum of all the values. (7*4=28)
Now, we can write this as a function, where we can represent the missing value as 'x'.
[tex]4+5+13+x=28[/tex]
In order to get the missing value, we must solve the equation.
Step 1: Simplify.
[tex]4+5+13+x=28\\22+x=28[/tex]
Step 2: Subtract 22 from both sides.
[tex]22+x=28\\22+x-22=28-22\\x=6[/tex]
x is equal to 6, which means the missing volume of gas is 6!
Im not sure how to find the missing angle
Answer:
Step-by-step explanation:
the question is asking for the length of the side labeled x
use Pythagoras' theorem to find that side
where c = x because c represents the hypotenuse in the theorem and x is on the hypotenuse in this problem
c = [tex]\sqrt{a^{2} + b^{2} }[/tex]
sooo plug in a = 14 and b = 10
c = [tex]\sqrt{14^{2} + 10^{2} }[/tex]
c = [tex]\sqrt{196+100}[/tex]
c = [tex]\sqrt{296}[/tex]
c= 17.20465..... ( that's the approx. length of side x in the problem )
since this is a right triangle we could use trigonometry to find the two angles use SOH CAH TOA to remember how those functions fit on the triangle.
Sin(Ф)=Opp/Hyp Cos(Ф)=Adj/Hyp Tan(Ф)=Opp/Adj
since we know the Hyp (hypotenuse) and the side adjacent will be the side with the 10 soooo...
Cos(Ф)=10/17.20465
Ф = arcCos(10/17.20465)
Ф = 54.4623° is the angle on the side with 10
the side with 14 then has an angle of 35.5376°
