Answer:

130

Step-by-step explanation:

The division of 91 by 0.7 gives 130.

Division is one of the four fundamental mathematical operations, along with addition, subtraction, and multiplication. Division is described as the separating of a large group into smaller groups so that each group has an equal number of things. In mathematics, it is an operation used for equal grouping and equal sharing.

We have to 91 by 0.7.

So, 91/ 0.7

= 91 x 10 / 7

= 13 x 7 x 10 / 7

= 13 x 10

= 130

So, the required quotient is 130.

Answer:

7550 years

Step-by-step explanation:

From;

N = Noe^-kt

No = inital amount of C-14 (at time  t = 0)

N = amount of C-14 at time t

k= 0.0001

t = time, in years

Now we have been told in the question that N =0.47 No

So we have;

0.47 No = Noe^-0.0001 t

0.47 No/No = e^-0.0001 t

0.47 = e^-0.0001 t

ln 0.47 = ln e^-0.0001 t

-0.7550 = -0.0001 t

t = 0.7550/0.0001

t = 7550 years

Answer:

For Company A to have a better deal, the truck must be driven more than 250 miles per day.

Step-by-step explanation:

Given that:

Rent per day of company A = $70

Per mile charges = $0.20

Let,

x be the number of miles.

A(x) = 0.20x + 70

Rent per day of company B = $20

Per mile charges = $0.40

B(x) = 0.40x + 20

For make Company A better deal,

A(x) > B(x)

0.20x+70 > 0.40+20

0.20x-0.40x>20-70

-0.20x>-50

Dividing both sides by -0.20

[tex]\frac{-0.20x}{-0.20}>\frac{-50}{-0.20}\\x>250[/tex]

Hence,

For Company A to have a better deal, the truck must be driven more than 250 miles per day.

Answer:

  y = 3x +3

Step-by-step explanation:

The midpoint of the given segment is a point on the line. That point is ...

  M = ((7, 4) +(-5, 8))/2 = (7-5, 4+8)/2 = (1, 6)

The difference between the end points can be helpful in writing the equation.

 (-5, 8) -(7, 4) = (-12, 4) = (Δx, Δy)

Then the general form of the equation of the perpendicular bisector can be written as ...

  Δx(x -Mx) +Δy(y -My) = 0 . . . . . where midpoint M = (Mx, My)

  -12(x -1) +4(y -6) = 0

Dividing by -4 and eliminating parentheses, we have ...

  3(x -1) -(y -6) = 0

  3x -y +3 = 0 . . . . general form equation for the line

  y = 3x +3 . . . . . . slope-intercept form equation

Answer:

113

Step-by-step explanation:

we need to know how much Lou has first !

so we have to do 682 / 6 which = 113

then 113 / 4 = 28.2

28.2 is how much Lou has

so we will go back and multiply the 4

28.2 x 4 =113

Answer:

Kelly has 248 songs on her music player.

Step-by-step explanation:

k=kelly, T= tiffany, and L = Lou

K= 4L, T = 6L

682= L + 4L + 6L

682 = 11L

682/11 = 11L/11

62 = L

So 4L = 248

Step-by-step explanation:

Since it is to the fifth power, you multiply the number 2 five times:

2 x 2 x 2 x 2 x 2 = 32

Answer:

The mean is 6.2

To get the mean you add up all the numbers and divide by how many you added in this case the sum of the numbers is 62 then divide by 10 as its the number of games played.

Answer:

answer is (c) it cannot be determined whether the circumference is the geometrical or not

Answer:

B

Step-by-step explanation:

To determine if a sequence is geometric, the terms need to have a common ratio. This means that to get from one term to the next, you need to multiply by the same number. Here's an example geometric sequence:

1) 2, 4, 8, 16, 32...

2) 4, 6, 9...

As you can see, to get from one term to the next in both of these sequences, you need to multiply by a certain number [the common ratio]. In sequence one, this number is 2. You need to multiply a term by 2 to get to the next term. In the second sequence, this number is 3/2. To find this certain number/common ratio, you can set the terms into ratios:

9/6=3/2

6/4=3/2

This ratio between the terms we get is the common ratio. Multiplying by this number will get you to the next term.

In this case [-4, -1, 1, -4...]:

[tex]\frac{-4}{1}=-4[/tex]

[tex]\frac{1}{-1} =-1[/tex]

[tex]\frac{-1}{-4}=\frac{1}{4}[/tex]

The ratios produced by the terms clearly aren't the same here, so the sequence is not geometric.

Just swap the colon (:) for a slash (/)

Answer:

Any of these should work for ya :)

 3/4 = 6/8 = 9/12 = 12/16

= 15/20 = 18/24 = 21/28 = 24/32

= 27/36 = 30/40 = 33/44 = 36/48

= 39/52 = 42/56 = 45/60 = 48/64

= 51/68 = 54/72 = 57/76 = 60/80

= 63/84 = 66/88 = 69/92 = 72/96

= 75/100 = 78/104 = 81/108 = 84/112

= 87/116 = 90/120 = 93/124 = 96/128

= 99/132 = 102/136 = 105/140 = 108/144

= 111/148 = 114/152 = 117/156 = 120/160

= 123/164 = 126/168 = 129/172 = 132/176

= 135/180 = 138/184 = 141/188 = 144/192

= 147/196 = 150/200 = 153/204 = 156/208

= 159/212 = 162/216 = 165/220 = 168/224

= 171/228 = 174/232 = 177/236 = 180/240

= 183/244 = 186/248 = 189/252 = 192/256

= 195/260 = 198/264 = 201/268 = 204/272

= 207/276 = 210/280 = 213/284 = 216/288

= 219/292 = 222/296 = 225/300 = 228/304

= 231/308 = 234/312 = 237/316 = 240/320

= 243/324 = 246/328 = 249/332 = 252/336

= 255/340 = 258/344 = 261/348 = 264/352

= 267/356 = 270/360 = 273/364 = 276/368

= 279/372 = 282/376 = 285/380 = 288/384

= 291/388 = 294/392 = 297/396 = 300/400

(fog)(x) = [tex] x [/tex]

Step-by-step explanation:

Given:

[tex] f(x) = \frac{x - 1}{3} [/tex]

[tex] g(x) = 3x + 1 [/tex]

Required:

(fog)(x)

SOLUTION:

(fog)(x) = f(g(x))

Substitute 3x + 1 into [tex] f(x) = \frac{x - 1}{3} [/tex]

f(g(x)) = [tex] \frac{(3x + 1)- 1}{3} [/tex]

[tex] = \frac{3x + 1 - 1}{3} [/tex]

[tex] = \frac{3x}{3} [/tex]

[tex] = \frac{x}{1} [/tex]

(fog)(x) = [tex] x [/tex]

Answer:

D. 3

Step-by-step explanation:

The sides with lengths 25 and 5 are corresponding, so their ratio is 25/5 = 5/1

The sides with lengths 18 - x and x are also in a 5 to 1 ratio.

5/1 = (18 - x)/x

5x = 18 - x

6x = 18

x = 3
