Answer:

4, 45, 75

Step-by-step explanation:

15 miles per 2 min = 7.5 miles per 1 min

2 min = 15 min

4 min = 30 min

6 min = 45 min

10 min = 75 min

Answer:

2.4

Step-by-step explanation:

set up an equation to find x, the number.

[tex]25x+8=68[/tex]

subtract 8 from both sides

[tex]25x=60[/tex]

divide both sides by 25 to get x (the variable) alone

[tex]x=\frac{60}{25}=\frac{12}{5}=2.4[/tex]

Answer:

Your answer is B.

Step-by-step explanation:

n>0 means n is greater than 0.

It is an open circle that is pointing to the right for positive values greater than 0.

Answer:Try B.

Step-by-step explanation:

The translation is 8 units to the right and 5 units downwards, and the scale factor is k = 0.8

First, we have a translation that goes from F to F', to identify it, we need to find the centers of the two circles.

F = (-5, 4)

F'= (3, -1)

To get the translation we take the difference between the two centers:

F' - F =  (3, -1) - (-5, 4) = (8, -5)

So the translation moves 8 units to the right and 5 units downwards.

To get the dilation we need to find the quotient between the radius of F' and the radius of F.

This is:

k =  4/5 = 0.8

So the scale factor is 0.8

[tex]\tt 3(x+2)-9=15-4(5x-2)[/tex]

To solve this equation, let's apply the distributive property:-

Multiple 3 by ( x+2)/ Subtract 9 from 6 = -3/ and then use the distributive property to multiply −4 by (5x-2) :-

[tex]\tt 3x - 3=15 - 20x+8[/tex]

Add 15 and 8 = 23

[tex]\tt 3x - 3=23 - 20x[/tex]

Now, add 20x to both sides:-

[tex]\tt 3x - 3=23 - 20x[/tex]

Combine like terms:-

[tex]\tt 23x-3=23[/tex]

Add 3 to both sides:-

[tex]\tt 23x=23+3[/tex]

[tex] \tt 23x=26[/tex]

Divide both sides by 23:-

[tex]\tt \: x = \dfrac{26}{23} [/tex]

Answer:

[tex]\left[\begin{array}{ccc}38&28&66\\22&12&34\\60&40&100\end{array}\right][/tex]

Step-by-step explanation:

70% of 40 is 28, with that number you can obtain the other data.

What I got is in the image below.

I got the rest of the numbers by subtracting and adding. I also managed to find the 70% by multiplying 40 (I subtracted 60 and 100 to get the total number of people who don't watch sports) by 0.7, getting that 28 of people who don't watch sports liked pop music. From there, getting the rest of the numbers is just a whole lot of adding and subtracting. I subtracted 60 and 34 to get the number of people who watch sports and like pop, which is 26. I also added 26 and 28 to get the total of people who like pop, which is 56. To get 46 for total number of people who don't like pop, I subtracted 40 and 28 which equals 12 (number of people who don't watch sports but don't like pop), then added 34 + 12 to get 46.

Answer:

x=12

Step-by-step explanation:

(9^5)(9^7)=9^x

282429536481=9^x

Step 1: Flip the equation.

9^x=282429536481

Step 2: Solve Exponent.

9^x=282429536481

log(9^x)=log(282429536481)(Take log of both sides)

x*(log(9))=log(282429536481)

x=log(282429536481)/log(9)

Finding the mean :

Absolute Mean Deviation of each term :

M.A.D. = 5 + 4 + 10 + 1 + 1 + 6 + 0 + 5 / 8

Answer:

x = 10.

Step-by-step explanation:

By similar triangles:

3x - 5 / (3x - 5 +10) = 20 / 28

3x-5 / 3x+5 = 5/7

7(3x - 5) = 5(3x + 5)

21x - 35 = 15x + 25

6x = 60

x = 10.

Answer:

x= 10

Step-by-step explanation:

By similar triangles:

3x - 5 / (3x - 5 +10) = 20 / 28

3x-5 / 3x+5 = 5/7

7(3x - 5) = 5(3x + 5)

21x - 35 = 15x + 25

6x = 60

x = 10.

Answer:

I round it to the whole number and degree.

<A = 33°

<C = 97°

C = 63

Step-by-step explanation:

Law of Sine: [tex]\frac{sinA}{A} =\frac{sinB}{B}= \frac{sin C}{C}[/tex]

[tex]\frac{sin(A)}{A} =\frac{sin(B)}{B}\\\frac{sin(A)}{104} =\frac{sin(50)}{49} \\\\sin(A)=\frac{104*sin(50)}{49}[/tex]

A = sin^-1 (104*sin(50)/49)

A = 33°

180° - <B - <A = <C

180° - 50° - 33° = 97°

[tex]\frac{sin(B)}{B}=\frac{sin(C)}{C} \\\\C =\frac{Bsin(C)}{sin(B)}\\\\C=\frac{104sin(97)}{sin(50)}\\\\C = 63[/tex]

Put in the formula

[tex]\\ \rm\Rrightarrow A=P(1+r)^t[/tex]

[tex]\\ \rm\Rrightarrow 7255=6000(1+0.055)^t[/tex]

[tex]\\ \rm\Rrightarrow 1.20917=(1.055)^t[/tex]

[tex]\\ \rm\Rrightarrow ln1.20917=tln1.055[/tex]

[tex]\\ \rm\Rrightarrow t=\dfrac{ln1.20917}{ln1.055}[/tex]

[tex]\\ \rm\Rrightarrow t=3.5years[/tex]

Answer:

4 years (nearest year) or

3.5 years (nearest tenth) or

3 years, 6 months and 17 days (most accurate)

Step-by-step explanation:

Annual Compound Interest Formula

[tex]\large \text{$ \sf A=P\left(1+r\right)^{t} $}[/tex]

where:

Given:

Substitute the given values into the formula and solve for t:

[tex]\implies \sf 7255=6000(1+0.055)^t[/tex]

[tex]\implies \sf 7255=6000(1.055)^t[/tex]

[tex]\implies \sf \dfrac{7255}{6000}=(1.055)^t[/tex]

Take natural logs of both sides:

[tex]\implies \sf \ln \left(\dfrac{7255}{6000}\right)= \ln (1.055)^t[/tex]

[tex]\textsf{Apply the power law}: \quad \ln x^n=n \ln x[/tex]

[tex]\implies \sf \ln \left(\dfrac{7255}{6000}\right)= t\ln (1.055)[/tex]

[tex]\implies \sf t=\dfrac{\ln \left(\dfrac{7255}{6000}\right)}{\ln (1.055)}[/tex]

[tex]\sf \implies t=3.547416819...[/tex]
