Step-by-step explanation:

${a}^{2} + {b}^{2} = {c}^{2} \\ {a }^{2} + {6}^{2} = {9}^{2} \\ {a }^{2} + 36 = 81 \\ {a}^{2} + 81 - 36 \\ {a}^{2} = 45 \\ \sqrt{a} = \sqrt{45} \\ a = 3 \sqrt{5}$

The owner of two hotels is ordering towels. He bought 15 hand towels and 43 bath towels for his hotel in Livingston, spending a

coldgirl [10]

Answer:

The cost of each Hand towels is $5 and Cost of each Bath towel is $11.

Step-by-step explanation:

Let the Cost of Each hand Towels be $'x'$ .

Let the Cost of Each Bath Towels be $'y'$ .

Now Given:

15 hand towels and 43 bath towels for his hotel in Livingston, spending a total of $548.

So we can say that;

$15x+43y=548$

$15x=548-43y\\\\x=\frac{548-43y}{15}$ ⇒ Equation 1

Also Given:

99 hand towels and 62 bath towels for his hotel in Lancaster, spending $1,177.

So we can say that;

$99x+62y =1177$ ⇒ Equation 2

Substituting the value of 'x' from equation 1 in Equation 2 we get;

$99\frac{(548-43y)}{15}+62y=1177\\\\33\frac{(548-43y)}5+62y=1177\\\\\frac{18084-1419y}5+62y=1177$

Now taking LCM to make the denominator common we get;

$\frac{18084-1419y}5+\frac{62y\times5}{5}=1177\\\\\frac{18084-1419y}5+\frac{310y}5=1177\\\\\frac{18084-1419y+310y}{5}=1177$

$18084-1109y=1177\times5\\\\18084-1109y=5885$

Combining the like terms we get;

$18084-5885=1109y\\\\12199=1109y$

Dividing both side by 1109 we get;

$\frac{12199}{1109}=\frac{1109y}{1109}\\\\y=\$11$

Substituting the value of y in equation 1 we get;

$x=\frac{548-43y}{15}=\frac{548-43\times11}{15}=\$5$

Hence The cost of each Hand towels is $5 and Cost of each Bath towel is $11.

Sanjit drives the 45 km distance between York and Leeds he then drives a further 42 km from Leeds to Blackpool

I am Lyosha [343]

Answer: His average speed for his total journey from York to Blackpool is approximately 61.41 km/h.

Step-by-step explanation:

$\text{ The average speed}=\frac{\text{Total distance covered}}{\text{Total time taken}}$

Since, The distance covered by him from York to Leeds = 45 km,

The speed when he covered this distance = 54 km/ h

Thus, the time taken by him in travelling from York to Leeds = 45/54 hours (Because, Time = Distance/speed)

Now, The distance covered by him from Leeds to Blackpool = 42 km,

The time taken by him in travelling from Leeds to Blackpool = 35 minutes = 35/60 hours

Hence, the total time taken by him in this journey

$=\frac{45}{54}+\frac{35}{60}=\frac{450+315}{540}=\frac{765}{540}=\frac{17}{12}$ hours

And, the total distance he covered= 45 + 42 = 87 km

Thus, His average speed

$=\frac{87}{17/12}= \frac{12\times 87}{17}=\frac{1044}{17}=61.4117647\approx 61.41\text{ km per hour}$
