can anyone help Please​

25

Step-by-step explanation

Let the ones's digit =x.

So, sum of the digits =7

Tens's digit =7−x

Original no. =10(7−x)+x=70−10x+x=70−9x

Reversed no. =10x+7−x=9x+7

2(orig no) = reversed no. −2

2(70−9x)=9x+7−2

140−18x=9x+5

27x=135

x=5

Ten's digit =7−5=2

No. =25

Answer:

The number of customers that were served per hour at this restaurant is 60 customers per hour

A linear equation is in the form:

y = mx + b

Where y,x are variables, m is the rate of change and b is the initial value of y.

600 customers were served during a 10-hour period of time. Hence:

slope = 600 customers / 10 hours = 60 customers per hour.

The number of customers that were served per hour at this restaurant is 60 customers per hour

The proportional relationship that represents the situation is:

y = 60x.

The graph is given at the end of the answer.

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

[tex]y = kx[/tex]

In which k is the constant of proportionality.

In this problem, 600 customers were served during a 10-hour period of time, hence:

k = 600/10 = 60.

And the equation is:

[tex]y = 60x, 0 \leq x \leq 10[/tex]

The graph is sketched at the end of this answer.

Answer:

106

Step-by-step explanation:

The given is a pentagon and the sum of interior angles is = 540

so to find the value of x:

132 + 90 + x + x + x = 540 add like terms

222 + 3x = 540 subtract 222 from both sides

3x = 318 divide both sides by 3

x = 106

A. Both [tex]f(x)[/tex] and [tex]g(x)[/tex] have the same domain of [tex](9, +\infty)[/tex].

In this question we must analyze the domain, range, x-intercepts and increase intervals:

[tex]Dom \{f(x)\} = \mathbb{R}[/tex]

[tex]Dom \{g(x)\} = \mathbb{R}[/tex]

Both functions are continuous.

[tex]Ran \left\{f(x)\right\} = (3.875, +\infty)[/tex]

[tex]Ran \{g(x)\} = (-5, +\infty)[/tex]

[tex]f(x):[/tex] [tex](x,y) = \emptyset[/tex]

[tex]g(x):[/tex] [tex](x,y) = (2.322, 0)[/tex]

[tex]f(x):[/tex] According to the graph, [tex]f(x)[/tex] increase over the interval of [tex](3.875, + \infty)[/tex].

[tex]g(x) :[/tex] According to the graph, [tex]g(x)[/tex] increase over the interval of [tex]\mathbb{R}[/tex]

After a quick analysis, we conclude that option A offer the best approximation to characteristics of both functions. [tex]\blacksquare[/tex]

The statement presents mistakes and is poorly formatted. Correct form is:

A. Both [tex]f(x)[/tex] and [tex]g(x)[/tex] have the same domain of [tex](9, +\infty)[/tex].

Step-by-step explanation:

please mark me as brainlist please

Answer:

Using Pythagorean theorem we can find the radius which is the distance between the center and any point along the circle:

r=((5-1)^2+(2-2)^2)^(1/2)

r=(4^2-0^2)^(1/2)

r=4 units.

Circumference=2pr so our circumference is 8p units^2

so about 25.13 u^2

With no limiting factors to the growth of the plants, the number of  months have passed since the plants were first introduced is 23.1.

Exponential function is the function in which the function growth or decay with the power of the independent variable. The curve of the exponential function depends on the value of its variable.

A type of plant is introduced into an ecosystem and quickly begins to take over.

A scientist counts the number of plants after m months and develops the equation to model the situation, which is given as,

[tex]p(m)=19.3(1089)^m[/tex]

Most recently, the scientist counted 138 plants.

[tex]138=19.3(1089)^m\\(1089)^m=7.15[/tex]

Taking log both sides of the equation,

[tex]\log(1.089)^m=\log7.15\\m\log(1.089)=\log(7.15)\\m=\dfrac{\log7.15}{\log(1.089)}\\m\approx23.1[/tex]

Thus, with no limiting factors to the growth of the plants, the number of  months have passed since the plants were first introduced is 23.1.

Answer: c. 1/6

Step-by-step explanation:

The least common demoninator would be 12, as 12 is a multiple of 4.

We can multiply the fraction 3/4 by (3/3)

3/4 = 3/4*(3/3)

= (3*3)/3*4)

= 9/12

We can plug in the value of 9/12 in as 3/4 back into the expression:

= 11/12 - 9/12

We can combine the numerators since there is a common denominator:

= (11-9)/12

= 2/12

Divide the numerator and denominator of this fraction by 2:

= 1/6

Answer:

The answer is 80°

Step-by-step explanation:

Here, we know that the sum of all interior angles of hexagon is equal to 720°

So,

x + x + 140 + 140 + 140 + 140 = 720

2x + 560 = 720

2x + 560 – 560 = 720 – 560

2x = 160

2x/2 = 160/2

x = 80°

Thus, The value of x is 80°

For Verification

x + x + 140 + 140 + 140 + 140 = 720

80 + 80 + 140 + 140 + 140 + 140 = 720

720 = 720

L.H.S = R.H.S

Hence Verified!
