Answer:
s = 2.5w + 10
Step-by-step explanation:
You have $10.00. Each week you save $2.50. The number of weeks you save w increases your savings s. Write an equation relating your savings s to the number of weeks you save w.
Your total savings (s) =
How many weeks you have been saving * how much you earn every week + the amount of money you already have.
So, the final equation should be:
w * 2.5 + 10 = s
Simplify.
s = 2.5w + 10
I hope this helps! Feel free to ask any questions!
If a measurement were given, could you know if it represented a perimeter, an area, or a volume?
Answer:
I mean, sure
Step-by-step explanation:
usually after the number theres a unit and an number next to it indicating the dimension it works in
so like perimeter is x cm^1

Step-by-step explanation:
Your bill for lunch was $12.86. How much would 20% tip be? What would your total be with tip included? Explain how you used math to come to your decision.
20% Tip = $2.58 Total Amount: $15.43
Step-by-step explanation:
An easy way to solve a problem, where the percentage ends in a 0, is to find 10% of the original number. 12.86 is our starting number, so finding 10% of that is simply moving the decimal place 1 to the left, making 10% = 1.29.
To find 20% Just Multiply 1.28 (10%) by 2, which is 2.58. Add this amount to 12.86 and you get $15.43.
Another way to solve the problem is simply to multiply $12.86 * 1.20, which would give you $15.43 as well.

Andrew bought 24 carpet tiles and 3 tins of paint.
The total cost was £100.20. Each tin of paint cost £13.16.
Find the cost of one carpet tile.
Answer:
Cost of one carpet tile = (Total cost-3*tin of paint cost)/24
=(100.20-3*13.16)/24=2.53
Hope this helps <3
Answer: £2.53
13.16 x 3 = 39.48
100.20 / 39.48 = 2.53

Help me with this please!!!!
Answer: x = 10
7x + 5 is equal to 9x - 15 because they have and share similar angles and verticies.
7x + 5 = 9x - 15
subtract 7x and and 15 to both sides. This leaves us with.
20 = 2x
Divide both sides by 2 to get x alone.
10 = x
Plug x back into original equation to check work.
7 (10) + 5 = 9 (10) - 15
70 + 5 = 90 - 15
75 = 75

Step-by-step explanation:
This table gives the value of an investment for the first 5 years after the initial investment was made. The data can be modeled using an exponential function.
Years 1 2 3 4 5
Investment value $1,050 $1,103 $1,160 $1,215 $1,280
Based on the data, which amount is closest to the value of the investment 10 years after the initial investment?
$1,350
$1,475
$1,625
$1,800
Answer:
C.) $1,625
Step-by-step explanation:
Going by the numbers on the graph, you can immediately tell $1,350 and $1,475 are way too low, so cancel those out and you get $1,625 and $1,800
From here, you can see that in 5 years it hasn't gone up by far, so it won't be 1,800$ by 10 years end, making the answer clear
You can just double 280 and get 560, which the closest answer is 1,625
It's really just a high-low estimate question, 2 answers are too high or low, one is close but not really, and one is just right- or inbetween
$1,625
The amount $1625 is closest to the value of the investment 10 years after the initial investment option third is correct.
What is an exponential function?It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent [tex]\rm y = a^x[/tex]
where a is a constant and a>1
Let's suppose the exponential function that model the problem is:
[tex]\rm y = ae^k^x[/tex]
Plug x = 1 and y = 1050
[tex]\rm 1050 = ae^k[/tex] ...(1)
Plug x = 2 and y = 1103
[tex]\rm 1103 = ae^2^k[/tex] ...(2)
Divide equation (2) with (1)
[tex]\rm e^k = 1.0504[/tex]
Taking ln to get the value of k
k = 0.0491
a = 999.69
The exponential function:
[tex]\rm y = (999.6902)e^{0.0491}^x[/tex]
Plug x = 10 years in the above function:
y = $1633.44
Which is close to $1625
Thus, the amount $1625 is closest to the value of the investment 10 years after the initial investment option third is correct.

Step-by-step explanation:
A boat is traveling at 43.2 m/s. It then goes down a faster part of the river and is now going 144
m/s which gave the boat an acceleration of 25.2 m/s2. How long did it take the boat to reach its
new speed?
Answer:
Step-by-step explanation:
boat was at 43.2 m/s speed increase to 144 m/s
if the boat was moving 0 m/s and increased to 144 m/s - 43.2 m/s accelerating at 25.2 m/s², it would take the same amount of time
25.2 m/s² × x seconds = (144 - 43.2) m/s solve for x in seconds
x seconds = 100.8 m/s / 25.2 m/s²
x seconds = 4 (m/s /ms²) = 4 (m/s × s²/m) = 4 seconds the units match
x = 4 seconds
Complete the following statements using m(x) = x² and n(x) = x – 3.
m(n(x)) = m(x – 3)
= (
x – 3
)²
n(m(x)) = n(x²)
= x² –
Because m(n(x)) is
n(m(x)), the composition of m and n is not commutative.
Therefore, function composition is not commutative.

Find the area of a trapezium whose parallel sides are 28.7 cm and 22.3 cm and distance between parallel sides is 16 cm.
Given:
The parallel sides of a trapezium are 28.7 cm and 22.3 cm.
The distance between parallel sides is 16 cm.
To find:
The area of a trapezium.
Solution:
The area of the trapezium is:
[tex]A=\dfrac{a+b}{2}h[/tex]
Where, [tex]a,b[/tex] are parallel sides and [tex]h[/tex] is the vertical distance between the parallel sides.
Putting [tex]a=28.7, b=22.3,h=16[/tex] in the above formula, we get
[tex]A=\dfrac{28.7+22.3}{2}\times(16)[/tex]
[tex]A=\dfrac{51}{2}\times 16[/tex]
[tex]A=51\times 8[/tex]
[tex]A=408[/tex]
Therefore, the area of the trapezium is 408 square cm.
