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

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

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.

Find the value of if the perimeter of the rectangle is 30inches. The length is 2x + 3and the width is x
Answer:
The perimeter of a rectangle is 30 meters. The length of the rectangles is 3 meters more than twice the width. Find the dimensions of the rectangle.
Step-by-step explanation:
Equation for Perimeter of a rectangle: Perimeter = 2W + 2L
Defining the variables, let
Width = x
Length = 2x+3 (3 more than twice the width)
Plugging everything into the equation
30= 2(x) + 2(2x+3) using the distributive property,
30=2x+4x+6 combining like terms
30=6x+6 subtracting 6 from both sides,
24=6x divide both sides by 6
4=x This means that the width is 4 m
To get the length, use the expression L=2x+3 and plug in x = 4 that was already solved for
L=2(4)+3
L=8+3 = 11 m
So the dimensions of the rectangle are width is 4 m and length is 11 m

Part B: Solve for the unknown variable of the larger floor.
Answer:
show stage and back stage
Step-by-step explanation:
The scale factor is 3 and the value of the unknown variable of the larger floor is 36 ft and this can be determined by using the given data.
Given :
Two-stage floors are in the shape of isosceles trapezoids. The small stage floor in the drama room is geometrically similar to the large stage floor in the auditorium.a) Let the scale factor be 'y'. So, the value of 'y' can be calculated as:
[tex]\begin{aligned}\\24 &= y \times 8\\y &= 3\\\end{aligned}[/tex]
So, the scale factor is 3.
b) The value of the unknown variable of the larger floor is calculated as:
[tex]\begin{aligned} \\12\times y &= x\\12\times 3& = x\\x&= 36\\\end{aligned}[/tex]
So, the value of the unknown variable of the larger floor is 36 ft.
