ank, the owner of Hank's Hot Dog Hut, deposited $175 this morning from his late-night sales. This afternoon, he deposited another $280 from lunch sales.

Answer:

Step-by-step explanation:

It takes Layla 45 minutes to make 9 bracelets on her own.

45 divided by 9 equals 5. It takes Layla 5 minutes to make one bracelet.

Layla and Amelia can make 9 bracelets in 20 minutes.

20 divided by 9 equals 2 and 2/9.

5 - 2 2/9= 2 7/9

2 7/9 times 9 equals 25

Amelia can make 9 bracelets in 25 minutes

So it takes Layla 56 minutes to make 9 ( 45 divided by 9 = 5) so that means in 20 minutes Layla will make 4 bracelets.

this means it will piece together as Layla would make 4 while Amelia makes 5. So i think on Amelia's own it'll take her 40 minutes.

so sorry if i'm wrong :(

Based on the relationship between the age of a tree and the inches in diameter, the age of a tree with 12 inches diameter is 100 years old.

The relationship between the age of a tree and the length of its diameter is such that from 4 inches in diameter, the age of the tree increases by 10 years for every 1 inch increase in diameter.

The last number of years shown in the table is 60 years which corresponds with 8 inches.

The number of years that a 12 inch tree would be is:

9 inches = 70 years

10 inches = 80 years

11 inches = 90 years

12 inches = 100 years

In conclusion, the tree would be 100 years.

Step-by-step explanation:

The domain is simply all of the x values. Since the ordered pairs are written as (x, y) ...Find the domain by listing all the x values from the relation (which in this case is the first value in each of the parentheses).

The amount at the end of three years is 1.06 times the initial amount.

Rate = 2%

Time = 3 Years

Let the principal amount be P

Simple interest = P * R * T

SI = ( P * 2 * 3 ) / 100

= 6P/100

= 0.06P

Amount = P + SI

= P + 0.06P

= P(1 + 0.06)

If the perimeter of  rectangle is 312 feet,

The length and width of the rectangle are 132 feet and 24 feet

let the width of the given rectangle be x feet

then as per the information provided in the question , the length of rectangle is 6x-12 feet

the parameter of the rectangle is the two times the sum of its length and breath = 2(l+ b)

We are already provided with the parameter of the rectangle as 312 feet

So, let us put the value of length and breath along with the parameter in the formula

312= 2( (6x-12) + x

312= 2( 6x-12 + x)

312= 2(7x-12)

312= 14x - 24

312+24 =14x

336=14x

therefore x= 24

Hence, the length and width of the rectangle are 132 feet and 24 feet

Therefore, line that are parallel have the same slope.

Therefore, if line one slope is 5, then the slope of the unknown line will be 5.

Hence,

y = 5x + b

let's find the y-intercept using (-8, -5)

-5 = 5(-8) + b

-5 = -40 + b

Answer:

area of a square= s^2

so the each side is 8

Answer:

Step-by-step explanation:

First, distribute the -2 to the p and +1 in the parentheses.

9-2(p+1)=4(p-8)

9-2p-2=4(p-8)

Then on the other side do the same thing distributing the 4 to the p and -8.

9-2p-2=4(p-8)

9-2p-2=4p-32

Now isolate the variable p by adding 2p to each side

9-2p-2=4p-32

9-2=6p-32

From here you subtract 9 from 2 and then add 32 to both sides.

7=6p-32

39=6p

finally you divide both sides by 6 to get p.

39/6=p

6.5=p

The younger sister is 29.

The older sister is 49.

Mr Fishman's age is 47.

Let:

The difference between the older sister and younger sister's age: y - x = 20 equation 1

Mr Fishman's is 11 years less than twice his young sister's age: 2x - 11 = c equation 2

The difference between Mr Fishman and his older sister's age : y - c = 2

y  - 2 = c equation 3

Let equation 2 and 3 be equal : 2x - 11 = y - 2

2x - y = 11 - 2

2x - y = 9

-y + 2x = 9 equation 4

The two equations that would be used are:

y - x = 20 equation 1

-y + 2x = 9 equation 4

Add both equations together

x = 29

Substitute for x in equation 1

y - 29 = 20

y = 29 + 20

y = 49

y - c = 2

49 - c = 2

c = 49 - 2

c = 47

48 persons make up a party. There are seven times more adults than children in the world. Males outnumber females two to one. If the party has five girls. The total number of male adults are15

The total number of people are in the party is equal to 48

Let the number of children be x

So, the number of adults in the party is equal to 7 x

x + 7 x =48 ( This is a linear equation)

So, the number of children in the comes to be 6

Number of adults in the party = 6 * 7 = 42

Now let number of males be y

So total number of females = 2 y

Y+2y = 48 ( This is a linear equation)

Y=16

Therefore, the number of males is 16 and number of females is 32

Number of children in the party is 6 and female child is equal to 5

Then, number of male children =6-5 = 1

So total males in the party is equal to 16

Adult males =total number of males - number of male children

Normal model for sizes is (7,1)

Here 5% of female customer have foot size in between 6-10

a)We were told that there are dress shoes in sizes 6 to 10 point, and the tailor believes that, with the exception of 5% of his female customers, the shoe would fit almost everyone. As a result, it accounts for 95 percent of female customers or women who try on his shoes, and we've been asked to determine what standard model for sizes is consistent.

b)The mean is 8 and the standard deviation is 2 points. So, we can say that x follows a normal model with a mean of 8 and a variance of 4 point right and in part b, we were asked whether a retailer should order more shoes in sizes 4 and 5 or more shoes in sizes 11 and 12 point so the best way to do this is to draw a balk curve or the symmetric table.

The equation of the line though the point (−4,−1) and perpendicular to the line y=25x+7 is y = -(1/25)*x - 21/25

We want to find a line perpendicular to y = 25x + 7, then the slope of our line must be the inverse of the opposite of 25, this is:

a = -(1/25)

Then our line is something like:

y = -(1/25)*x + b

And we want this to pass through (-4, -1), then:

-1  =-(1/25)*-4 + b

-1 = 4/25 + b

-1 + 4/25 = b

-25/25 + 4/25 = b

-21/25 = b

Step-by-step explanation:

Using proportions, it is found that:

a) They can paint 2.8 pictures in one hour.

b) The rate per hour is of 131.2 magazines.

c) The unit rate is of 0.86 problems per minute.

d) He can make 92.5 tacos in one hour.

e) He walks 3.75 miles in one hour.

The code is of 148.79.

A proportion is a fraction of a total amount, and the measures can be related using a rule of three, which derives from proportional relationships.

Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.

A unit rate is given by amount or fraction divided by time. Hence, for item a, it is given as follows:

4/5/(2/7) = 4/5 x 7/2 = 2.8.

They can paint 2.8 pictures in one hour.

For item b, we have that:

328/2.5 = 131.2.

The rate per hour is of 131.2 magazines.

For item c, we have that:

15/17.5 = 0.86.

The unit rate is of 0.86 problems per minute.

For item d, we have that:

185/2 = 92.5.

He can make 92.5 tacos in one hour.

For item e, we have that:

0.75/0.2 = 3.75.

He walks 3.75 miles in one hour.

For the code, the letters are given as follows:

E = 3.75, B = 131.2, D = 92.5, A = 2.8, C = 0.86.

Hence the code is given by:

E(B - D) + (A + C) = 3.75(131.2 - 92.5) + (2.8 + 0.86) = 3.75(38.7) + 3.66 = 145.13 + 3.66 = 148.79.

The code is of 148.79.
