Ms. Banks walks at about 3 feet per second. How many miles per day could she travel.if she walked without
taking a break?
1
0.81 miles per day
16.36 miles per day
49.09 miles per day
2.04 miles per day

Answers

Answer:

49.09 miles per day

Step-by-step explanation:

There are 5,280 feet in one mile.

There are 60 seconds in one minute.

3 * 60 = 180 feet per minute

There are 60 minutes in one hour.

180 * 60 = 10,800 feet in one hour.

There are 24 hours in one day.

10,800 * 24 = 259,200 feet per day.

Divide to find how many miles she can walk.

259,200 / 5,280 = 49.09 miles

3x-29=6x-7 what is x

Answers

Answer:

Step-by-step explanation:

You want to get x on one side and the constants on the other. First subtract both sides by 3x to get:

-29 = 3x - 7

Now add 7 to both sides to get:

-22 = 3x

Divide each side by 3 to get:

x = -22/3

3x-29=6x-7
-6. -6
-3x-29=-7
+29 +29
-3x=22
x=-22/3

4 Answers: A, C, E, and F

================================================

Explanation:

Choice A is true assuming we have [tex]a_n = (-1)^n*b_n[/tex]

In this case, [tex]a_n = (-1)^n*\frac{1}{\sqrt{n}}[/tex] and [tex]b_n = \frac{1}{\sqrt{n}}[/tex]

--------

Choice B is false. See choice A above.

--------

Choice C is true. The sequence [tex]\{b_n\}[/tex] is decreasing. As n gets larger, [tex]b_n[/tex] gets smaller. This is because the denominator is growing larger with the numerator held constant.

--------

Choice D is false. This contradicts choice C.

--------

Choice E is true since the denominator is growing forever

This is similar to [tex]\displaystyle \lim_{n \to \infty} \frac{1}{n} = 0[/tex]

--------

Choice F is true due to choices C and E being true.

--------

Choice G is false because it contradicts choice F.

Answer:

Step-by-step explanation:

First you would find what the difference is between the school enrollment

you would do 1456 - 1234 = 222

Then you would divide 1234/1456 = 84.75% to see the total percentage

The increase however has a percentage of .18%

To check your work you would do .18 x 1234 = 222.12 ( round to the nearest whole number so it would just be 222) then add 1234+ 222 = 1456!

Graph the image of the given triangle after the transformation that has the rule (x, y)→(x−5, y+6). Select the Polygon tool. Then, click the points of the triangle vertices to create the triangle by connecting the sides.

Answers

Answer:

Step-by-step explanation:

Transformation involves changing the position of a shape in the coordinate.

See attachment for the image of the triangle

Assume the triangle is triangle ABC.

The coordinates of ABC are:

[tex]\mathbf{A = (-1,-4)}[/tex]

[tex]\mathbf{B = (-2,-7)}[/tex]

[tex]\mathbf{C = (5,-6)}[/tex]

The transformation rule is given as:

[tex]\mathbf{(x,y) \to (x -5,y+6)}[/tex]

So, we have:

[tex]\mathbf{A' = (-1 -5,-4+6)}[/tex]

[tex]\mathbf{A' = (-6,2)}[/tex]

[tex]\mathbf{B' = (-2 -5,-7+6)}[/tex]

[tex]\mathbf{B' = (-7,-1)}[/tex]

[tex]\mathbf{C' = (5 -5,-6+6)}[/tex]

[tex]\mathbf{C' = (0,0)}[/tex]

So, the coordinates of the new triangle would be:

[tex]\mathbf{A' = (-6,2)}[/tex]

[tex]\mathbf{B' = (-7,-1)}[/tex]

[tex]\mathbf{C' = (0,0)}[/tex]

Answer:

x=2

Step-by-step explanation:

first, let's distribute.

3(x+1)-2=x+5

3x+3-2=x+5

then, let's combine like terms.

3x+1=x+5

now, we subtract x on both sides.

2x+1=5

subtract 1 on both sides.

2x=4

divide by 2 on both sides.

x=2

The answer to the equation is x=2

240 in a ratio of 3:5?

Answers

ANSWER: let the ratios are 3x and 5x
therefore,3x+5x=240
8x=240
x=30
so,3x=3×30=90
5x=5×30=150
so,we divide 240 in 90 and 150 to get ratio 3:5

The number who needs to be made into a ratio = 240

Total number of parts = 3 + 5

= 8 parts

Each part = 240 ÷ 8

= 30

Then three parts = 30 × 3 = 90

Five parts = 30 × 5 = 150

Then , the ratio will be = 90 : 150

Therefore , 240 in a ratio of 3 : 5 = 90 : 150 .

The length of a rectangle is four more than three times it’s width. The perimeter is 64 inches

Answers

Answer:

Length: 25, Width: 7

Step-by-step explanation:

Let the width be represented by w. We can then assume that the length is equivalent to 3w+4

So, we can set the equation 2(3w+4)+2(w). Simplify to 8w+8=64

Simplify the equation and solve for w, which is 7

Plug into the the length, which is 3w+4

Answer:

Length: 25 inches

Width: 7 inches

Step-by-step explanation:

Perimeter = 2L + 2W

Length: 3w + 4

Width: w

64 = 2(3w + 4) + 2w

64 = 6w + 8 + 2w

64 = 8w + 8

56 = 8w

w = 7

Length: 3(7) + 4 = 25

Width: 7

Answers

Answer:

Option (4)

Step-by-step explanation:

[tex]m(\widehat{FC})[/tex] = 180° [FC is the diameter]

[tex]m(\widehat{FC})=m(\widehat{FB})+m(\widehat{BC})[/tex]

180° = 125° + [tex]m(\widehat{BC})[/tex]

[tex]m(\widehat{BC})=180-125[/tex] = 55°

[tex]m(\widehat{FBD})=360-m(\widehat{FED})[/tex]

[tex]=360-[m(\widehat{FE})+m(\widehat{ED})][/tex]

[tex]=360-[m(\widehat{BC})+m(\widehat{ED})][/tex] [Since [tex]m(\widehat{FE})=m(\widehat{BC})[/tex] arcs created by vertical angles]

b. -13pi/3
c. 57pi/2
d. 11pi/7

I know the answer to the first one is 1.88495559215. However, following the formula I was given by my teacher gives me decimals that are higher than the decimal for 2pi or lower than 0, so the other questions keep being wrong. Can someone please help?? I have no idea what to do.

Answers

Answer:

a. 1.88495559215 radians

b. 5.23598775598 radians

c. 1.57079632679 radians

d. 4.93678845564 radians

Step-by-step explanation:

You want the coefficient of pi to be between 0 and 2. That is, you want its value modulo 2--the remainder from division by 2.

a. 13/5 = 2.6; 2.6 mod 2 = 0.6. 0.6π ≈ 1.88495559215 (as you know)

b. -13/3 = -4 1/3; -4 1/3 mod 2 = 1 2/3*. 5/3π ≈ 5.23598775598

four pumpkins weigh 26 pounds altogether. Pumkin one weighs four less than three times the weight of Pumkin threee. Pumkin four weighs twice as much as pumkin One. Pumpkin Two weighs five more pounds than Pumkin three. What does each pumpkin weigh

Answers

Answer:

5, 8, 3, 10 lbs.

Step-by-step explanation:

We can solve this using a system of equations! We will call pumpkins [tex]a, b, c, d[/tex].

Our equations are thus:

[tex]a + b + c + d = 26[/tex]

[tex]a = 3c - 4[/tex]

[tex]d = 2a[/tex]

[tex]b = c + 5[/tex]

So now we just need to solve this system of equations.

We can start by solving for the value of pumpkin [tex]c[/tex] and go from there. So first we substitute some equations around.

First we write out pumpkin [tex]d[/tex] in terms of [tex]a[/tex].

[tex]d = 2a = 2(3c - 4) = 6c - 8[/tex]

And now we put the three equations into the first equation:

[tex]a + b + c + d = 26\\(3c-4)+(c+5)+(c)+(6c-8)=26[/tex]

Then we simplify to get:

[tex]11 c - 7 = 26[/tex]

[tex]11c = 33\\c = 3[/tex]

So we know pumpkin [tex]c[/tex] weighs 3 pounds.

Then we use the equations from before to get the value of the other pumpkins:

[tex]a = 3c-4 = (3*3)-4=9-4=5\\d = 2a = 2*5=10\\b = c + 5 = 3 + 5 = 8[/tex]

And we can check our results by putting into first equation:

[tex]5+8+3+10=26[/tex]

So it works out!

Thus our pumpkins weigh 5, 8, 3, 10 lbs each.

what are the measures of angles a,b,c ?

Answers

Answer:

a=30 , b=60, c=105

Step-by-step explanation:

a=30 [Being vertically opposite angle]

Now,

a+b+90=180 [Being the sum of interior angles of a triangle]

or, 30+b+90=180

or, b+120=180

or, b=180-120

so, b= 60

Again,

c+75= 180 [Being linear pair]

or, c=180-75

so, c= 105
