Answer:
The distance between the points (3, 6) and (8, -1)
[tex]d=8.6[/tex]Step-by-step explanation:
Given the points
(3, 6)(8, -1)Finding the distance between the points (3, 6) and (8, -1)
(x₁, y₁) = (3, 6)
(x₂, y₂) = (8, -1)
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
[tex]=\sqrt{\left(8-3\right)^2+\left(-1-6\right)^2}[/tex]
[tex]=\sqrt{5^2+7^2}[/tex]
[tex]=\sqrt{25+49}[/tex]
[tex]=\sqrt{74}[/tex]
[tex]d=8.6[/tex]
Thus, the distance between the points (3, 6) and (8, -1)

Pete purchased 5 drinks and 6 snacks and spent a total of $22.50. Jaime purchased 1 drink and 9 snacks and spent a total of 24.75 each drink costs the same amount. Each snack costs the same amount write a system of linear equations that can be used to find thr coet of one drink and one snack.
Answer:
[tex]5x+6y=22.50\\x+9y=24.75[/tex]
Step-by-step explanation:
Cost of 5 drinks and 6 snacks = $22.50
Cost of 1 drink and 9 snacks = $24.75
Each drink costs the same and each snack costs the same.
Let cost of each drink = $[tex]x[/tex]
Let cost of each snack = $[tex]y[/tex]
As per the question, writing the system of equations:
[tex]5x+6y=22.50 ...... (1)\\x+9y=24.75 ...... (2)[/tex]
Let us use elimination method, to find the cost of each drink and cost of each snack.
Multiplying equation (2) by 5 and then subtracting equation (1) from it:
[tex]45y - 6y = 123.75 - 22.5 \\\Rightarrow 39y = 101.25\\\Rightarrow y \approx \$2.60[/tex]
Using equation (1):
[tex]5x+2.6 \times 6 = 22.5\\\Rightarrow 5x = 22.5 - 15.6\\\Rightarrow 5x = 6.9\\\Rightarrow x = \$1.38[/tex]
Cost of each drink = $1.38
Cost of each snack = $2.60

Answer:x=9
Step-by-step explanation:
Answer: x = 9
Step-by-step explanation:
9x + 5 = 86
9x + 5 - 5 = 86 - 5 (you subtract 5 from both sides to isolate the 9x)
9x = 81
9x/9 = 81/9 (to get the value of x, you divide both sides by 9)

a rectangular pool is 3 times as long as it is wide. a redwood walkway 2m wide with an area of 208 m borders the pol. what are the dimensions of the pool
The dimensions of pool 25.5m width, 76.5m length.
Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure.
let x= Width
formula of area of rectangle = Length x Width
Given;
[tex]\begin{aligned}&(3 x+2)(x+2)=3 x^{2} +208 \\&3x^{2} +8 x+4=3x^{2} +208\end{aligned}[/tex]
We can substrate [tex]3x^{2}[/tex] and 4 from both sides.
8x = 204
x = 25.5m width, 76.5m length.
(25.5)(76.5) = 1950.75 [tex]m^{2}[/tex]
(27.5)(78.5) = 2158.75 [tex]m^{2}[/tex]

Answer:
7/3 mph
Step-by-step explanation:
knowing that:
distance traveled = velocity * time - velocity of the water * time
4 = v1 * 1.5 + v2 * 1.5
4 = v1 * 2 - v2 * 2
solve the system in any way you want,

Data defines a claim that has been verified, examined, and backed up by numerous pieces of evidence.
What do you mean by data?
Data is information that has been transformed into a format that is useful for transfer or processing in computing. Information that has been converted into binary digital form for usage with contemporary computers and communication channels is referred to as data.
As the volume of data being collected and stored increases, so do the units used to measure it. For instance, the relatively new concept of a "brontobyte" refers to a unit of data storage that is 10 to the 27th power of bytes.
File formats can be used to store data, such as ISAM and VSAM in mainframe systems. Another file format for storing, converting, and processing data is comma-separated values.

Ajay just started a running plan where he runs 20 miles the first week and then increases the number of miles he runs by 5% each week. If he keeps up this plan for 14 weeks, how many total miles would Ajay have run, to the nearest whole number?
If Ajay keeps up his plans for 14 weeks he would have run total of 391 miles.
The sum of n terms of a Geometric Progression ( a,ar,ar²,ar³,...,arⁿ⁻¹ ) is given by
Sₙ=a(rⁿ-1)/(r-1)
where, a=first term
and r = common ratio
In the given question ,
Ajay runs 20 miles in first week , ...(i)
In second week the distance is increased by 5% of the previous week .
So in second week he runs = 20+5% of 20
[tex]=20+\frac{5}{100} *20[/tex]
=20(1+5/100)
=20(105/100)
=[tex]20\times(\frac{21}{20})[/tex] ...(ii)
In third week Ajay runs = 20(21/20) + 5% of 20(21/20)
=[tex]20(\frac{21}{20} )+\frac{5}{100} *20(\frac{21}{20} )[/tex]
=20(21/20)[1+5/100] ..taking 20(21/20) common
[tex]=20(\frac{21}{20} )[\frac{105}{100} ][/tex]
=20(21/20)(21/20)
=20(21/20)² ...(iii)
Similarly in 14th week Ajay Runs = 20(21/20)¹³ . ...(iv)
Total miles run by Ajay = miles run in first week + miles run in 2nd week + ...+ miles run in 14th week.
Substituting the values of equation (i), (ii), (iii) and (iv) we get
Total miles run by Ajay = [tex]20+20(\frac{21}{20} )+20(\frac{21}{20} )^{2} +...+20(\frac{21}{20} )^{13}[/tex]
The above series represent a Geometric Progression with common ratio as (21/20) and first term as 20.
Substituting in the formula for Sum of Geometric Mean we get
[tex]S_{14} =20(\frac{(\frac{21}{20} )^{14} -1}{\frac{21}{20} -1} )[/tex]
S₁₄=20*((1.05)¹⁴-1)/(1.05-1)
=20*(1.9799-1)/0.05
=20*0.9799/0.05
=20*19.598
=391.96
≅391
Therefore , If Ajay keeps up his plans for 14 weeks he would have run total of 391 miles.
