The tuition for a state resident to attend a particular state college is $8000 this year. The tuition is expected to increase 6.25% per year for the next 5 years. Write an equation to represent the situation.
Answer:
8,000^0.0625=5
Step-by-step explanation:
Lol I was doing my homework rn and I wasn't 100% sure of my answer so I looked it up on brainly. So an exponential equation should look like this e^a=b so with the three values $8,000 , 6.25% , and 5 years I kind of just mixed around the numbers a bit in the exponential equation till one worked. So yeah...
Answer:
f(t)=8000e^(0.0625)(5)
Step-by-step explanation:
exponential growth function is f(t)=Pe^(rt)
where P is starting value, or price
e is the e on you calculator
r is rate of increase, in this case 6.25/100 is 0.0625, which is the rate
t is the time given
Hope this helps, also had this on my math hw today lol :)
determine the missing value!
Hi there!
missing value: -9
1.Multiply the two negative:
[tex]-2[/tex]·[tex]-4=-8[/tex]
2.Find the value of 72*-8:
[tex]72*-8=-9[/tex]
Therefore, the missing value is -9.
The first term in a sequence is 5. Each new term in the sequence is obtained by adding 4 to the previous term. Determine an equivalent position-to-term formula. Your answer should be an expression in terms of .

3(x -2 = 3x - 5 is it a no slolution or one solution or x= 0 or infinite
Answer:
no solution
Step-by-step explanation:
Answer:
Step-by-step explanation:
3(x-2)=3x-5
3x-6=3x-5 now add 6 to both sides
3x=3x+1 subtract 3x from both sides
0=1
Zero is not equal to one so there is no value of x that satisfies the original equation. There is no solution.
Sam’s best friend kisses her 20 times while sam’s BF kisses her 102 times
How many times was Sam kissed
Tell your reasoning ?
Answer:
122 times
Step-by-step explanation:
20+102=122
(what is this question lol)
Answer:
Well. Depending on Sam's age, she could've been kissed many times. Not just boy her bf or bestie, anyone could kiss her throughout her life time. Your question is very vague and can have many answers. But I'll take a guess and say she was kissed more than 122 times.

Peter has built a gazebo, whose shape is a regular heptagon, with a side length of $1$ unit. He has also built a pathway around the gazebo, of constant width $1$ unit, as shown below. (Every point on the ground that is within $1$ unit of the gazebo and outside the gazebo is covered by the pathway.) Find the area of the pathway.
Answer:
Area of pathway = 10.375 unit²
Step-by-step explanation:
Given - Peter has built a gazebo, whose shape is a regular heptagon, with
a side length of 1 unit. He has also built a pathway around the
gazebo, of constant width 1 unit, as shown below.
To find - Find the area of the pathway.
Proof -
Central angle = [tex]\frac{360}{7}[/tex] = 51.43°
Now,
Central angle / 2 = [tex]\frac{360}{14}[/tex] = 25.71°
And
height = [tex]\frac{1}{2}.\frac{1}{tan25.41}[/tex] = 1.038
Now,
Inner area of gazebo = 7·[tex]\frac{1}{2}[/tex]·1·(1.038) = 3.634 unit²
Outer area of gazebo = ([tex]\frac{2.038}{1.038}[/tex])²·(3.364) = 14.009 unit²
∴ we get
Area of pathway = Outer area - Inner area
= 14.009 - 3.634
= 10.375 unit²
⇒Area of pathway = 10.375 unit²
Q.1 Write the algebraic expressions
(i) Three times p added to four times r
(ii) The difference of 2p and 3q when 2p is less than 3q
(iii) Two-thirds of x added to 2y [3]
help?!
Answer:
(i) 4r + 3p (ii) 3q - 2p when 3q > 2p (iii) 2y + 2/3 x [not sure what [3] means]
Step-by-step explanation:
So for part (i) 3 multiply p added to 4 times r = 3p + 4r
For part (ii) since subtraction can seem like a negative number you stipulate that 3q is greater than 2p so that is will hold true!
(iii) I'm not sure what the [3] means but just using the numbers [tex]\frac{2}{3}[/tex]x, since of means multiply and add 2y then you have 2y + [tex]\frac{2}{3}[/tex] x

Answer:
3 pieces
Step-by-step explanation:
Given: Figure
To find: Number of 8.5 in. × 11 in. pieces used to cover the floors of a room and a hallway in her dollhouse
Solution:
In the given figure, AC = 22 in.
AB + BC = 22 in.
AB + EF = 22 (As BC = EF being opposite sides of rectangle)
AB + 10 = 22
AB = 22 - 10 = 12 in.
Area of rectangle ABGH = AB × AH = 12 × 5 = 60 square inches
(area of rectangle = length × breadth )
CE = CD + DE = AH + GF (As CD = AH and DE = GF)
CE = 5 + 15 = 20 inches
Area of rectangle BCEF = BC × CE = 10 × 20 = 200 square inches
(BC = EF = 10 in.)
Total area of the figure = Area of rectangle ABGH + Area of rectangle BCEF = 60 + 200 = 260 square inches
Area of pieces of felt = 8.5 × 11
So,
Number of pieces required = Total area of the figure / Area of pieces of felt = 3 pieces

15. Metal A has a density of 2.4g/cm3 and Metal B has a density of 1.8
g/cm3. Their masses are combined in the ratio 2:3 to make metal C which
has a mass of 60 grams. Find the density of the metal C*
Answer:
The density of the metal C is 2 g/cm³
Step-by-step explanation:
The parameters of the two metals are;
The density of the Metal A = 2.4 g/cm³
The density of the Metal B = 1.8 g/cm³
The ratio in which their masses are combined to make the metal C= 2:3
The mass of the metal C, m = 60 grams
Let, 'x', represent the mass of the metal A in the 60 grams of the metal C and let 'y' represent the mass of the metal B in the 60 grams of the metal C
Let the ratio of the metals A and B in the metal C = x:y = 2:3
Therefore;
The mass of the metal A in the metal C, x = (2/(3 + 2)) × 60 g = 24 g
The volume of the metal A in the metal C, V₁ = (24 g)/(2.4 g/cm³) = 10 cm³
The mass of the metal B in the metal C, y = (3/(3 + 2)) × 60 g = 36 g
The volume of the metal B in the metal C, V₂ = (36 g)/(1.8 g/cm³) = 20 cm³
The volume of the metal C, V = V₁ + V₂ = 10 cm³ + 20 cm³ = 30 cm³
The density of the metal C = ρ = m/V
ρ = (60 g)/(30 cm³) = 2 g/cm³
The density of the metal C, ρ = 2 g/cm³

A blue light flashes every 8 minutes while a pink light flashes every 54 minutes.
Both lights flash together at 2pm.
When is the next time that both lights will flash together again?
Answer:
5:36 pm
Step-by-step explanation:
54 x 4= 216 and 8 x 27= 216 so since they both flashed at 2:00 pm 216 minutes later it will be 5:36 pm and they will both flash at the same time.

Answer:
a. Pop
b. 30 CDs
c. 230 CDs
Step-by-step explanation:
Given that "O" represents 20 CDs
a. The CD that was the mode is the CD that has as much "O", which is Pop.
Mode = Pop
b. Number of Rock CDs = 3 × 20 = 60 CDs
Number of Classical CDs = 1½ × 20 = 30 CDs
Therefore, 30 more CDs of Rock were sold than Classical CDs were sold
c. Pop = 5*20 = 100 CDs
Jazz = 2*20 = 40 CDs
Classical = 1½*20 = 30 CDs
Rock = 3*20 = 60 CDs
Total sold altogether = 100 + 40 + 30 + 60
= 230 CDs

A. 241 feet
B. 358 feet
C. 258 feet
D. 341 feet
Answer: A. 241 feet
Step-by-step explanation:
The figure shows two rectangular triangles.
These triangles are similar since they have two identical angles:
the first angle is 90 degrees;
the second angle is equal because the law of reflection states that the angle of incidence is equal to the angle of reflection.
The law of reflection states that the angle of incidence is equal to the angle of REFLECTION.
Let's make the proportion:
[tex]\dfrac{4}{273} =\dfrac{5}{x} \\\\x=\dfrac{273 \cdot 5}{4} =341.25 \: (feet)\\[/tex]
It takes a minimum of 100 feet for a parachute to open and safely land without injury, so:
341.25 - 100 = 241.25 (feet)
241.25 ≈ 241 (feet)
Logan is 2 years older than Lindsey. Five years ago, the sum of their ages was 30. Find Lindsey’s
current age.
Answer:
lindsey = x = 19
logan = x + 2 = 21
Step-by-step explanation:
lindsey =x
logan = x + 2
-------
5 yrs back
lindsey = x - 5
logan = x + 2 - 5 = x - 3
~~~~~~~~~~
x- 5 + x - 3 = 30
x + x - = 30 +5 +3
2x = 38
x = 38/ 2 = 19
A service station sells gasoline for $3.25 per gallon
and diesel fuel for $3.00 per gallon. On Monday, the
service station's revenue from selling a total of 131

many gallons of diesel fuel did the service station sell
on Monday? Show your work
A) 35
B) 55
C) 76
D) 86
Answer:
86
Step-by-step explanation:
86 x 3 + 45 x 3.25 = ? If it equals 404.25 than the answer is 86
76 x 3 + 55 x 3.25 = ? If it equals 404.25 than the answer is 76
55 x 3 + 76 x 3.25 = ? If it equals 404.25 than the answer is 55
35 x 3 + 96 x 3.25 = ? If it equals 404.25 than the answer is 35
The number you multiply by 3 is the answer.
86 x 3 + 45 x 3.25 = 404.25
