This question is based on the concept of solving a two linear equation.

Thus, the cost of one bath towel is $9 and one hand towel is $4.

Given:

Number of  ordered of hand towels is 27 and bath towels is 48 and for a bill of $540 for the first hotel.

Number of  ordered of hand towels is 50 and bath towels is 24 and for a bill of $416 for the other hotel.

We need tom determined the cost of one hand towel and one bath towel.

According to the question:

Let the  hand towels be h  and bath towels be b.

Therefore, equation of first hotel is

27h + 48b = 540........(1)

Equation of second hotel is

50h + 24b = 416.........(2)

Now, solving both equation for h and b.

Equation (2) multiplying by -2.

-100 h -48 b = - 832..................(3)

Now, solve equation (1) and (3)

27h + 48b = 540  and -100h - 48b = - 832

⇒ -73 h = - 292

⇒ h = -292 / -73

⇒ h = 4

Therefore, the cost of 1 hand towel is $4.

Now, putting the value of h = 4 in equation (1).

⇒ 27(4) + 48b = 540

⇒ 108 + 48b = 540

⇒ 48b = 540 - 108

⇒ 48b = 432

⇒ b = 432/48

⇒ b = 9

Therefore, the cost of 1 bath towel is $9.

Thus, the cost of one bath towel is $9 and one hand towel is $4.

Answer:

c.10.6

Step-by-step explanation:

we take sin the angle on the length of the side that opposite to it ...

The value of x from the triangle is x = 10.6

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the triangle be represented as ABC

Now , the measure of hypotenuse of the triangle = 15

Let the angle be θ = 45°

From the trigonometric relations ,

sin θ = opposite / hypotenuse

On simplifying the equation , we get

sin 45° = x / 15

where sin 45° = 0.7071

So , the value of x = 0.7071 x 15

The value of x = 10.6

Hence , the value of x from the triangle is x = 10.6

Hunter can make a maximum of 59 cups before he runs out of money.

An inequality is an expression that shows the non equal comparison of two or more variables and numbers.

Let x represent the number of cups that hunter can buy, He already spent 520 cents ($5.2) hence:

0.75x ≤ 50 - 5.2

x ≤ 59.7

Hunter can make a maximum of 59 cups before he runs out of money.

Answer:The weight of Euclid is 10.625 pounds, and the weight of Riemann is 21.25 pounds.

Let the current weight of Euclid = x

Let the current weight of Pythagoras = T

Let the January weight of Pythagoras = y

The expression that represents the given scenario is written as;

when Pythagoras lost 13 pounds: T =  y - 13

when Pythagoras gains 1.2 times Euclid's weight: = T + 1.2x

when Pythagoras weight is 1/4 pound less than weight in January:

T + 1.2x + 0.25 = y

y- 13 + 1.2x + 0.25 = y

1.2x - 12.75 = 0

Euclid's weight is calculated as follows;

1.2x = 12.75

Answer: This question does not make sense since 2 minus 4 is -2 and 7 > -2, which means this inequality is true by itself. There are no "solutions" to this inequality since there are no variables. Maybe you made a typo?

Edit: I found the actual question on the internet (it's 7 > z - 4) and the answers are 6, 7, and 10.

Find a where a=y2-y1 /x2-x1

y2=13,y1=5 x2=5,x1=3

substituting the values

a=13-5/5-2

a=8/2

a=4

substituting a into the formular

y=4x+b

taking x and y values let say 3 and 5 for x and y

the equation becomes

5=4(3)+b

5=12+b

5-12=b

-7=b

substituting the values of a and b into the equation

y=4x-7

when x=0

y=4(0)-7

y=0-7

Hi there!

a)

We can approximate g'(3) by finding the slope of g(t) over an interval containing t = 3.

We can use the endpoints t = 1 and t = 5 min for the best estimate.

[tex]slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{20.5-15.1}{5-1} = \boxed{1.35 \frac{ft^3}{min^2}}[/tex]

This means that the rate of grain being added to the silo is INCREASING at a rate of 1.35 ft³/min². (Or in other words, the grain is being poured at an increasingly greater rate)

b)

The total amount of grain added is the integral of g(t), so:
[tex]\text{total amount of grain} = \int\limits^8_0 {g(t)} \, dt[/tex]
We can do a right riemann sum by using the right endpoints (t = 1, t = 5, t = 6, t = 8) to calculate.

Riemann sums are essentially rectangles added up to calculate an approximate value for the area under a curve.

The bases are the spaces between each value in the chart, while the heights are the values of g(t).

Using the intervals and values in the chart:

[tex]1(15.1) + 4(20.5) + 1(18.3) + 2(22.7) = \boxed{160.8 ft^3}[/tex]

c)
We can subtract the two integrals to find the total amount of unspoiled grain.

With g(t) being fresh grain and w(t) being spoiled grain, let y(t) represent unspoiled grain.

[tex]y(t) = \int\limits^8_0 {g(t)} \, dt - \int\limits^8_0 {w(t)} \, dt[/tex]

Use a calculator to evaluate:
[tex]y(t) = 160.8 - \int\limits^8_0 {w(t)} \, dt = 160.8 - 99.05 = \boxed{61.749 ft^3}[/tex]

d)
We can do the first derivative test to determine whether the amount of grain is increasing or decreasing. (Whether the first derivative is positive or negative at this value).

For the above integral, we know that the derivative is:
[tex]y'(t) = g(t) - w(t)[/tex]

Plug in the values for t = 6:

[tex]w(6) = 32 \cdot \sqrt{sin(\frac{\pi (6)}{74})} = 16.06[/tex]
[tex]y'(6) = g(6) - w(6) = 18.3 - 16.06 = 2.23 \frac{ft^3}{min}[/tex]

This value is POSITIVE, so the amount of unspoiled grain is INCREASING.

Answer:  

7

Step-by-step explanation:

8 divided by 56 equals 7

Answer:

  1/7 acre

Step-by-step explanation:

The number of acres planted is presumed to be proportional to the number of pounds of seeds:

  acres/pounds = 8/56 = x/1

  x = 1×8/56 = 1/7

  1/7 acre can be planted per pound of seed.

_____

Additional comment

When you recognize that 56 = 8×7, there is a tendency to want to divide 56 by 8. That would result in the unit rate ...

  (56 lb)/(8 ac) = 7 lb/ac

That is, it takes 7 pounds of seed to plant 1 acre. The question asks how many acres can be planted with 1 pound. Clearly, that is 1/7 of the amount of seed required for 1 acre, so 1 pound will plant 1/7 acre.

The monthly cost is a function of the charge for a single user and the cost of additional users. The monthly cost increases with the number of additional users.
