Answer:

20.47.

Step-by-step explanation:

You need to 56.34, by 35.87. And you get your answer. 20.47!

Answer:

$52.45

Step-by-step explanation:

the tax is $2.50, if we add that to $49.95 we get $52.45

Total cost will be $52.45.

What is Percentage?

A relative value indicating hundredth part of any quantity is called percentage.

Given that;

Cost of shoes = $49.95

Tax = 5%

Now,

The value of tax = 49.95 × 5%

                         = 49.95 × 5/100

                         = 2.50

So, Total cost =  $49.95 + $2.50

                     = $52.45

Thus, Total cost will be $52.45.

Step-by-step explanation:

hope this helped.. :)

[tex]1\frac{13}{15}[/tex] is the solution for [tex]3\frac{10}{15}[/tex] - [tex]1\frac{12}{15}[/tex]

Fractions represent the parts of a whole or collection of objects.

The given expression is

[tex]3\frac{10}{15}[/tex] - [tex]1\frac{12}{15}[/tex]

Firstly we need to convert this mixed fraction to improper fraction.

Improper fractions are fractions whose numerator is greater than denominator.

((15×3)+10)/15 -  ((15×1)+12)/15

(45+10)/15 - (15+12)/15

55/15-27/15

15 is the LCM

(55-27)/15

28/15

Now we convert this to improper fraction

[tex]1\frac{13}{15}[/tex]

Hence [tex]1\frac{13}{15}[/tex] is the solution for [tex]3\frac{10}{15}[/tex] - [tex]1\frac{12}{15}[/tex].

Answer:

m= 120 - 6*d

Step-by-step explanation:

budget is $120 per 1 month, spends $6 per 1 day

on the the table you have 2 columns: one labele it "days" and one "$ spent" and fill it in:  

days: 1,2,3,4,..

$ spent: 6, 6*2=12, 6*3= 18, 6*4= 32,...

on the graph lable the horizontal axis "days" and the vertical axis "$ spent"

now plot the points (1,6), (2,12),(3,18), ..., and draw a line trough them

the equation is

m= 120 - 6*d

so after 20 days for example, out of 120 will have m=120-6*20=120-120=0,

$0 wil have in 20 days

Answer:

[tex]y=\frac{9}{4}x-\frac{55}{4}[/tex]

Step-by-step explanation:

Slope-intercept form: y = mx + b

Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]

Given points: (3, -7), (7, 2)

(3, -7) = (x1, y1)

(7, 2) = (x2, y2)

To write the equation in slope-intercept form, we need to find the slope(m) and the y-intercept(b) of the equation.

First, let's find the slope. To do this, input the given points into the slope formula:

[tex]\frac{2-(-7)}{7-3}[/tex]

Simplify:

2 - (-7) = 2 + 7 = 9

7 - 3 = 4

[tex]\frac{9}{4}[/tex]

The slope is [tex]\frac{9}{4}[/tex].

To find the y-intercept, input the slope and one of the given points(in this example I'll use point (7, 2)) into the equation and solve for b:

[tex]2=\frac{9}{4}(7)+b[/tex]

[tex]2=\frac{63}{4}+b[/tex]

[tex]-\frac{55}{4} =b[/tex]

The y-intercept is [tex]-\frac{55}{4}[/tex].

Now that we know the slope and the y-intercept, we can write the equation:

[tex]y=\frac{9}{4}x-\frac{55}{4}[/tex]

Answer:

-3

1.You can recognize exponential and linear function by their graph.Linear functions are straights while exponential functions are curved lines.You can also recognize them by the change in your.If the same number is being added to y,then the function has a constant change and is linear.3:-An example of a exponential function is the growth of bacteria and A common equation,y=mx+b y=mx+b,(namely the slope-intercept form,which we will learn more about later)is a example of a linear function.2:-For constant increments in x,a linear growth would increase by a constant difference,and an experimental growth would increase by a constant ratio.

Step-by-step explanation:

∵ In the rhombus, all the sides are equal in length

∵ MNOP is a rhombus

∵ MN = NO = OP = PM

∵ MN = 9x - 77

∵ OP = 3x + 7

→ Equate them to find x

∴ 9x - 77 = 3x + 7

→ Add 77 to both sides

∴ 9x = 3x + 84

→ Subtract 3x from both sides

∴ 6x = 84

→ Divide both sides by 6

∴ x = 14

→ Substitute the value of x in the expression of OP to find its length

∵ OP = 3(14) + 7 = 42 + 7

∴ OP = 49

∵ All the sides are equal in length

∴ MP = 49

∵ The diagonals of the square bisect each other

∵ STUV is a square

∵ SU and TV are its diagonals

∴ W is the mid-point of SU and TV

∴ SW = WU

∵ SW = 2x + 13

∵ WU = 8x - 41

→ Equate them to find x

∴ 8x - 41 = 2x + 13

→ Add 41 to both sides

∴ 8x = 2x + 54

→ Subtract 2x from both sides

∴ 6x = 54

→ Divide both sides by 6

∴ x = 9

→ Substitute x in the expression of SW to find it

∵ SW = 2(9) + 13 = 18 + 13

∴ SW = 31

∵ SU = SW + WU

∵ SW = WU

∴ SU = 31 + 31 = 62

∵ Diagonals of the square are equal in length

∴ SU = VT

∴ VT = 62

Sure, if u want to ask a question click question, however you need to answer questions to recieve points in order for you to ask questions. So answers some questions then you can ask  

Step-by-step explanation:

Answer:

(a) The exponential function representing the number of people who had watched the video [tex]t[/tex] hours after the initial observation is [tex]n(t) = 129\cdot 1.3^{\frac{t}{3} }[/tex].

(b) As [tex]n(120) < 5\times 10^{6}[/tex], we conclude that this video is not going "viral".

Step-by-step explanation:

Statement is incomplete. The complete statement is:

An internet analytics company measured the number of people watching a video posted on a social media platform. The company found 129 people had watched the video and that the number of people who had watched it was increasing by 30% every 3 hours.

(a) Write an exponential function for the number of people A who had watched the video n hours after the initial observation.

(b) A video is said to go "viral" if the number of people who have watched the video exceeds 5 million within 5 days (120 hours). Would this video be considered to have gone viral?

(a) From the statement of the problem we get the following relationship:

[tex]\frac{n_{i+1}}{n_{i}}= r^{[(i+1)-i]}[/tex] (Eq. 1)

Where:

[tex]n_{i}[/tex] - i-th number of people watching a video, dimensionless.

[tex]n_{i+1}[/tex] - (i+1)-th number of people watching a video, dimensionless.

[tex]r[/tex] - Increase ratio, dimensionless.

For Induction Theorem, we get the following relatioship for [tex]i = 0[/tex]:

[tex]\frac{n_{1}}{n_{o}} = r^{1-0}[/tex] (Eq. 2)

For [tex]i = m[/tex], the following relationship is constructed:

[tex]\left(\frac{n_{1}}{n_{o}} \right)\cdot \left(\frac{n_{2}}{n_{1}} \right)\cdot ...\cdot \left(\frac{n_{m+1}}{n_{m}} \right) = r^{m}[/tex]

[tex]\frac{n_{m+1}}{n_{o}} = r^{m}[/tex](Eq. 3)

And for [tex]i = m+1[/tex], we have the following expression:

[tex]\left(\frac{n_{1}}{n_{0}} \right)\cdot \left(\frac{n_{2}}{n_{1}} \right)\cdot ...\cdot \left(\frac{n_{m+2}}{n_{m}} \right) = r^{m+1}[/tex]

[tex]\frac{n_{m+2}}{n_{0}} = r^{m+1}[/tex](Eq. 4)

If we multiply (Eq. 3) by the (m+1)-th ratio based on (Eq. 1):

[tex]\left(\frac{n_{m+1}}{n_{o}}\right)\cdot \left(\frac{n_{m+2}}{n_{m+1}} \right) = r^{m} \cdot r[/tex]

[tex]\frac{n_{m+2}}{n_{o}} = r^{m+1}[/tex]

Which is (Eq. 4) and the exponential function is represented by:

[tex]n_{i+1} = n_{o}\cdot r^{i}[/tex], [tex]i\in \mathbb{N}_{O}[/tex] (Eq. 5)

As the number of people is increased at constant rate every 3 hours, we get that [tex]i[/tex] is:

[tex]i = \frac{t}{3}[/tex], [tex]t \in \mathbb{R}[/tex], [tex]t \geq 0[/tex] (Eq. 6)

Where [tex]t[/tex] is the time, measured in hours.

Then, the exponential function is:

[tex]n(t) = n_{o}\cdot r^{\frac{t}{3} }[/tex] (Eq. 7)

Where [tex]n_{o}[/tex] is the initial number of people watching the video, dimensionless.

If we know that [tex]n_{o} = 129[/tex] and [tex]r = 1.3[/tex], then the exponential function representing the number of people who had watched the video [tex]t[/tex] hours after the initial observation is:

[tex]n(t) = 129\cdot 1.3^{\frac{t}{3} }[/tex]

(b) If we know that [tex]t = 120\,h[/tex], then we evaluate the exponential function:

[tex]n (120) = 129\cdot 1.3^{\frac{120}{3} }[/tex]

[tex]n(120) = 4.659\times 10^{6}[/tex]

As [tex]n(120) < 5\times 10^{6}[/tex], we conclude that this video is not going "viral".
