each day last week, Ms. wilson walked3/4 mile. what is the total distance, in miles, that Ms. Wilson walked in 4 days?

Answers

Answer 1
Hey there! :D

Since she walks 3/4 a mile a day, we can multiply that by 4.

3/4= .75

4*.75= 3

She walked 3 miles in 4 days.

I hope this helps!

Answer 2

Taking into account the rule of three, the total distance that Ms. Wilson walked in 4 days is 3 miles.

Rule of three

In first place, the rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

That is, what is intended with it is to find the fourth term of a proportion knowing the other three.  

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied.

To solve a direct rule of three, the following formula must be followed, being a, b and c known data and x the variable to be calculated:

a ⇒ b

c ⇒ x

So: [tex]x=\frac{cxb}{a}[/tex]

Total distance that Ms. Wilson walked

You can applied the following rule of three: if each day last week, Ms. Wilson walked [tex]\frac{3}{4}[/tex] mile, in 4 days what is the total distance that Ms. Wilson walked?

[tex]total distance=\frac{4 daysx\frac{3}{4} miles }{1 day}[/tex]

total distance= 3 miles

Finally, the total distance that Ms. Wilson walked in 4 days is 3 miles.

Use the Distributive Property to find (g−7)(g−2).

Answers

You need to use foil here (first, outer, inner, last).
gxg=g^2
gx2=2g
7xg=7g
7x2=14
g^2-2g-7g+14   then simplify   g^2-9g+14   is the answer

Final answer:

The product of (g-7)(g-2) is found by applying the Distributive Property, which results in g² - 9g + 14.

Explanation:

To use the Distributive Property to find the product (g−7)(g−2), we need to multiply each term in the first parenthesis by each term in the second parenthesis. This gives us:

g × g = g²

g × (−2) = − 2g

(−7) × g = − 7g

(−7) × (−2) = 14

Combining these we get g² - 2g - 7g + 14. Simplifying by combining like terms, we obtain:

g² - 9g + 14

Therefore, the product (g−7)(g−2) using the Distributive Property is g² - 9g + 14.

tevin is 202 years old Catherine is 30 years old how many years until Tevin age is 5 * Katherine's age

Answers

that time is x

tevin+x = 5 times (catherine+x)

202+x=5(30+x)
distribute
202+x=150+5x
minus x both sides
202=150+4x
minus 150 both sides
52=4x
divide both sides by 5
13=x

in 13 years

To find out how many years until Tevin's age is 5 times Katherine's age, we set up an equation and solve for x, finding that it will take 13 years.

The question is asking us to find out how many years until Tevin's age is 5 times Katherine's age. Let's denote the number of years until this happens as 'x'.

Currently, Tevin is 202 and Katherine is 30.

In x years, Tevin will be 202 + x years old and Catherine will be 30 + x.

Therefore, we want to find x such that:

202 + x = 5(30 + x)

This can be solved as follows:

202 + x = 150 + 5x

Now, we subtract 5x from both sides:

202 - 4x = 150

Subtract 202 from both sides:

-4x = -52

Divide by -4:

x = 13

Therefore, it will take 13 years for Tevin's age to be 5 times Katherine's age.

Find the intersection of the two planes with equations 5(x − 1) + 2y + (z + 1) = 0 and (x − 1) + 7y − (z + 1) = 0. (use the parameter t. enter your answers as a comma-separated list of equations.)

Answers

Given:
P1: 5(x-1)+2y+1(z+1)=0
P2: 1(x-1)+7y-1(z+1)=0
Need the intersection of the planes P1 and P2 (a line)

By inspection of the equations, 
normal to P1: N1<5,2,1>
normal to P2: N2<1,7,-1>
Direction vector, V, of the required line is the cross product of P1 & P2:
   i  j   k
  5 2  1
  1 7 -1
=V<-9, 6, 33>

Since P1 passes through point (1,0,-1), the parametric equation of the required line is <1-9t, 0+6t, -1+33t>

L: 
Final answer:

The intersection of two planes can be found by solving the system of equations formed by the equations of the planes. In this case, the intersection is given by the equations x = (4 - 9y) / 6, y = y, and z = -3 - (23y/6), where y can be any real number.

Explanation:

The intersection of two planes can be found by solving the system of equations formed by the equations of the planes.

To find the intersection, we can set the two equations equal to each other and solve for x, y, and z.

Rewrite the equations in standard form: 5x - 5 + 2y + z + 1 = 0 and x - 1 + 7y - z - 1 = 0Add the equations together: 6x + 9y = 4Solve for x in terms of y: x = (4 - 9y) / 6Substitute the value of x into one of the original equations to solve for z: 5((4 - 9y) / 6 - 1) + 2y + (z + 1) = 0Simplify and solve for z: z = -3 - (23y/6)

Therefore, the intersection of the two planes is given by the equations x = (4 - 9y) / 6, y = y, and z = -3 - (23y/6), where y can be any real number.

You are scheduled to receive $38,000 in two yeara. when you receive it, you will invest it for 10 more years at 6.0 percent per yeat. how much will you have in 12 years?

Answers

Final answer:

After receiving $38,000 and investing it at a 6.0 percent interest rate per year for 10 years, the student will have approximately $68,052.19 in 12 years.

Explanation:

To find out how much the student will have in 12 years after receiving $38,000 and investing it for 10 years at a 6.0 percent interest rate per year, we need to calculate the future value of the investment using the formula for compound interest.

The formula for the future value FV of an investment over time is given by:

FV = PV * (1 + r)^n

Where:

PV = Present Value of the investment (the initial amount of money)

r = annual interest rate (expressed as a decimal)

n = number of years the money is invested

In this case:

PV = $38,000

r = 0.06 (which is 6.0 percent expressed as a decimal)

n = 10

Plugging these values into the formula, we get:

FV = $38,000 * (1 + 0.06)^10

FV = $38,000 * (1.06)^10

FV = $38,000 * 1.790847

FV = $68,052.186

Therefore, the student will have approximately $68,052.19 in 12 years.

Naomi's fish is 40 millimeters long.her guinea pig is 25 centimeters long. How much longer is her guinea pig than her fish

Answers

Answer:

The guinea pig is 210 mm longer than Naomi's fish

or

The guinea pig is 21 cm longer than Naomi's fish

Step-by-step explanation:

Remember that

1 cm=10 mm

Convert cm to mm

guinea pig ------> 25 cm=25*10=250 mm

Subtract the length of Naomi's fish from the length of her guinea pig

so

250-40=210 mm

Convert to cm

210 mm=210/10=21 cm

Jeanne thinks that x+x is the same as x•x. Is this true? Why? Why not?

Answers

generally, x • x is accepted to mean "x times x" or "x multiplied by x"

and x+x means "x plus x" or "x added to x"

let's try by subsituting numbers for them
if we can find one case where the statement "x+x is the same as x•x" is false, then it is not true


let's try x=4
x+x=x•x
4+4=4•4
8=16
false



so it is not true
(x+x is equal to 2x, so therefor if we were to solve 2x=x•x, we would get that it is only true for x=2 and x=0)

it is not always true

It depends on the number. Generally, it is false, expect in a few certain cases, such as 2 for example, as:

2 + 2 = 4

2 x 2 = 4

however, most other numbers do not work, such as, for example, 5

5 + 5 = 10

5 x 5 = 25

So it really depends on what "x" is.

How can the effect of an outlier be overcome in an experiment that examines a random sample of a population? A) Discard 50% of the data. B) Examine a larger random sample of the population. C) Examine a smaller random sample of the population. D) There is no way to overcome the effect of an outlier.

Answers

C) Examine a smaller random sample of the population. The outlier is far away from the others so if the sample is smaller it may not be included in the sample.

Answer with explanation:

Outlier, in a data set are those real numbers called variates , if we consider two consecutive real numbers in that data set, when data is arranged in ascending or descending order the difference looks filthy,or ambiguous.

For, example , 13,45,  23.45, 35.45, 49.45,55.45, 80.45.

So, we can say that ,applying the above definition , 80.45 is an outlier.

Outliers affect the mean and Standard deviation.

→If you discard 50 % of the data , to get the better result in an experiment,the data set will become smaller and getting accurate result will be a task similar to catch a  ruffian who is riding in a four wheeler and you are running behind him on footsteps.

→Similarly, Examining a smaller random sample of the population will not give accurate result.

Most of the Outliers lie either on right or left of Data set when arranged in ascending or descending order.

To overcome the effect of an outlier,we should consider large sample to get better result, as leaving some variates from right or left will have little effect on the result.

Option B: Examine a larger random sample of the population.

Mr. Fry is building a fence around his pool. •Length of the fence is 60 feet. •Width of the fence is 30 feet. How many yards of fence will Mr. Fry build? A) 30 yards B) 60 yards C) 90 yards D) 540 yards i need help!!!!!!!!!

Answers

Mr. Fry will need 60 yards of fencing to encircle his pool, as the perimeter of the rectangular pool area is 180 feet and there are 3 feet in a yard.

To determine the total amount of fencing Mr. Fry will need, we calculate the perimeter of the rectangular area around the pool. The perimeter can be found by doubling the length then adding this to double the width. Therefore:

Perimeter = 2× Length + 2× Wid
= 2 × 60 feet + 2 × 30 feet
= 120 feet + 60 feet
= 180 feet

Now, knowing that 1 yard equals 3 feet, we can convert feet into yards:

Yards = Feet ÷ 3
= 180 feet ÷ 3
= 60 yards

Hence, Mr. Fry will need 60 yards of fence for his pool.

To determine the number of yards of fence Mr. Fry will build, we calculate the perimeter of the rectangular area (2 x (60 + 30) feet = 180 feet) and then convert it to yards (180 feet / 3 = 60 yards).

Mr. Fry is building a fence around his pool and wants to know how many yards of fence he will need. The fence has a length of 60 feet and a width of 30 feet. To find the total length of the fence in yards, we first calculate the perimeter of the rectangular fence which is 2 x (length + width). So, the perimeter in feet is 2 x (60 + 30) = 180 feet. Since 1 yard is equal to 3 feet, we divide the total number of feet by 3 to get the measurement in yards: 180 feet / 3 = 60 yards. Therefore, Mr. Fry will build 60 yards of fence.

Sally has a photograph that has an area of 35 square inches. She creates 2 enlargements of the photograph. The enlargements have areas of 140 square inches and 560 square inches. In each photograph, the length is 1 2/5 times the width. Select which of thr following could be th dimensions of the original photograph or one of the enlargements. Mark all that apply

5 inches by 7 inches
20 inches by 28 inches
7 inches by 20 inches
21 inches by 15 inches
10 inches by 14 inches

Answers

The area of the photograph is:
 A = (w) * (l)
 Where,
 w: width
 l: long
 Substituting:
 35 = (w) * (1.4w)
 35 = 1.4 * w ^ 2
 w = root (35 / 1.4)
 Dimensions of the original photograph:
 w = 5 in
 l = 1.4 * (5) = 7 in
 Dimensions of extension 1:
 
k = (140) / (35) = 4
 w = 4 * 5 = 20 in
 l = 4 * 7 = 28 in
 Dimensions of extension 2: 
 k = (560) / (35) = 16
 w = 16 * 5 = 80 in
 l = 16 * 7 = 112 in

 Answer:
 5 inches by 7 inches
 20 inches by 28 inches

The potential dimensions that could represent the original photograph and its enlargements, with the length being 1 2/5 times the width, are 5 by 7 inches for the original photograph, and 20 by 28 inches and 10 by 14 inches for the enlargements.

To find the dimensions of Sally's original photograph and the enlargements with the area having the given ratio of length to width as 1 2/5, we need to understand the relationship between the area of two similar objects and their linear dimensions. We are given that the original photograph has an area of 35 square inches, and the enlargements have areas of 140 and 560 square inches. With the length being 1 2/5 times the width in each case, we can work out the possible dimensions for these photographs.

Now, let's consider the list of dimensions provided and determine which ones correspond to an area ratio that matches the original photograph or the enlargements:

5 inches by 7 inches: This has an area of 5 x 7 = 35 square inches, so it could be the original photograph.20 inches by 28 inches: This has an area of 20 x 28 = 560 square inches, which is one of the enlargements.7 inches by 20 inches: The ratio of length to width here is not 1 2/5, so this option is not correct.21 inches by 15 inches: This does not have an area that matches either the original photograph or the enlargements and the ratio of length to width is also not 1 2/5.10 inches by 14 inches: This gives an area of 10 x 14 = 140 square inches, which matches the first enlargement.

Conclusively, only some of the dimensions given match the requirements: 5 inches by 7 inches for the original photograph, 20 inches by 28 inches and 10 inches by 14 inches for the enlargements. They adhere to the concept that the ratio of their areas equals the ratio of the squares of their linear dimensions due to scaling.
