If a ÷ b = 2 and b ÷ c =3/4, what is the value of c ÷ a? Express your answer as a common fraction.
Thx guys!

Answer:

The function y = 5 [tex](.98)^{x}[/tex] represents exponential decay

The percentage rate of change is 2%

Step-by-step explanation:

The formula of the exponential growth is y = a [tex](1+r)^{x}[/tex], where

The formula of the exponential decay is y = a [tex](1-r)^{x}[/tex], where

Let us solve the question.

∵ y = 5 [tex](.98)^{x}[/tex]

→ Compare it with the forms above

∴ a = 5

∵ The rate of change is .98

∵ .98  < 1

→ That means the rate of change is decreasing

∴ The function y = 5 [tex](.98)^{x}[/tex] represents exponential decay

→ From the 2nd form above

∵ (1 - r ) = .98

→ Subtract 1 from both sides

∴ 1 - 1 - r = .98 - 1

∴ - r = - .02

→ Divide both sides by -1

∴ r = .02

→ Multiply it by 100% to change it to a percentage

∵ .02 × 100% = 2%

∴ r = 2%

∴ The percentage rate of change is 2%

So... This is it

1. JK = LM, JKM = LMK -> This is given information.

- From this given information, we know:

1. 2 congruent sides

2. 2 congruent angles

Now all we have to do is find one more side to prove SAS triangle congruence.

Next, we notice that the side MK is used by both the triangles we are trying to prove congruent. So we can say "MK = MK" by the reflexive property. (Since they share the same side).

Then, we can say triangle JMK is = triangle LKM because of SAS congruence.

*Please note the = signs I used should be actually congruence signs*

Answer:

first of all there are many ways to compare numbers. example

I don't know how to compare them but I try my best

Step-by-step explanation:

the first 3 numbers have only one digit but the 4th has 2 digits.but it in my opinion you don't want this answer.

so this is not the reason

3 have 2 factor

6 have 4 factor

9 have 3 factor

12 have 5 factors

so as the number increase the factors should increase but 9 has less factors than 6 .so I think 9 is the different one

Answer:

[tex]a = \frac{(b - c)}{c} \\ ac = (b - c) \\ ac + c = b \\ c(a + 1) = b \\ c = \frac{b}{(a + 1)} [/tex]

Answer:

2 1/3

Step-by-step explanation:

1 3/4  is equivalent to 7/4

1 1/3 is equivalent to 4/3

7/ 4 x 4/3

reduce with greatest common factor so the two 4 are out (show a line crossing out the top and bottom 4 )

now you're left with 7 x 1/3 = 7/3

7/3 = 2 1/3

The product of two given mixed fractions is [tex]2\frac{1}{3}[/tex].

The given mixed fractions are [tex]1\frac{3}{4}[/tex] and [tex]1\frac{1}{3}[/tex].

The product of two fractions is the product of the numerators and the product of the denominators.

Product of two fractions = Product of their denominators / Product of their numerators.

Here, the mixed fraction [tex]1\frac{3}{4}[/tex] can be written as [tex]\frac{7}{4}[/tex] and the mixed fraction [tex]1\frac{1}{3}[/tex] can be written as [tex]\frac{4}{3}[/tex].

Now, 7/4 × 4/3

= 7/3

= [tex]2\frac{1}{3}[/tex]

Therefore, the product of two given mixed fractions is [tex]2\frac{1}{3}[/tex].

16/21

Step-by-step explanation:

Divide both sides by 7 to get 1/8

2/3 = 7/8

1/7 x 2/3 = 7/8 x 1/7

2/21 = 1/8

Then multiply both sides by 8 to get 8/8 which is 1

8/1 x 2/21 = 1/8 x 8/1

16/21 = 1

Answer:

4y = -x + 31

Step-by-step explanation:

Given that one equation in a system of equations is y = 4x - 5 write a second equation to complete the system if the solution to the system is (3,7)

Since the solution of the system is (3, 7), that means the two lines of equations meet or intersect at point X = 3 and Y = 7

Let assume that the two equations are perpendicular to each other. Then, there slope can be expressed as

M1M2 = -1

Where M1 = 4

Find M2

4M2 = -1

M2 = -1 / 4

Using general linear equation

Y = MX + C

Let's find C by substituting Y, X and M2

7 = -1 /4( 3 ) + C

7 = -3/4 + C

C = 7 + 3/4

C = 31/4

Substitute C back into the equation

Y = -1/4X + 31/4

4y = -x + 31

Therefore, the second equation is

4y = -x + 31

7 hours and 30 minutes

Step-by-step explanation:

[tex]240 \div 4 = 60km \: per \: h[/tex]

[tex]450 \div 60 = 7.5 = 7h \: 30min[/tex]

It will take motor bike 7.5 hours to cover 450 Km of distance.

Speed of a body is defined as the distance travelled by it per unit time taken to cover the distance.

Mathematically-

S = Δd/Δt  or   S = {d(2) - d(1)}/{t(2) - t(1)}

It is a scalar quantity as it only has magnitude and no direction.

Given is a motor bike travels 240 km ins 4 hours.

We can calculate the speed of the bike as -

s = 240/4 = 60 Km/hr

Then, the time taken to cover 450 Km will be -

t = 450/60

t = 7.5 hours

Therefore, it will take motor bike 7.5 hours to cover 450 Km of distance.

Answer:

answer will be 5/17 as I have just substitute the number

The ratio of [tex]a[/tex] to [tex]b[/tex] is [tex]6[/tex] to[tex]1[/tex] and the ratio of [tex]b[/tex] to [tex]c[/tex] is [tex]12[/tex] to [tex]1[/tex], then the value of [tex]\frac{2a + 3b}{4b + 3c}[/tex]  is  [tex]\frac{180}{51}.[/tex]

Ratio is used to compare to things i.e. numbers, size etc.

We have,

[tex]\frac{a}{b} = \frac{6}{1}[/tex]  and  [tex]\frac{b}{c} = \frac{12}{1}[/tex]

From the above given data we have to make value [tex]b[/tex] same in both ratios;

Therefore multiply [tex](\frac{a}{b})[/tex] ratios from [tex]12[/tex],

We get,

[tex]\frac{a}{b} = \frac{72}{12}[/tex]   and   [tex]\frac{b}{c} = \frac{12}{1}[/tex]

So,

[tex]a=72,\\b=12,\\c=1[/tex]

Now, putting above values in [tex]\frac{2a + 3b}{4b + 3c}[/tex],

[tex]=\frac{2(72) + 3(12)}{4(12)+ 3(1)}[/tex]

[tex]=\frac{180}{51}[/tex]

Hence we can say that The ratio of [tex]a[/tex] to [tex]b[/tex] is [tex]6[/tex] to [tex]1[/tex] and the ratio of [tex]b[/tex] to [tex]c[/tex] is [tex]12[/tex] to [tex]1[/tex], then the value of [tex]\frac{2a + 3b}{4b + 3c}[/tex]  is  [tex]\frac{180}{51}.[/tex]

Answer:

The missing angle is about 27.92°.

Step-by-step explanation:

This is a tangent equation, as there is no hypotenuse value. I'll use x as the missing angle.

tan(x) = opposite/adjacent

tan(x) = 20/38

tan(x) = 0.52631578947368421052631578947368

tan(x) ≈ 0.53

Now, we have to reverse.

tan⁻¹(0.53) = x

27.92358972 = x

x ≈ 27.92°
