Answer:

y + 3 = (1/9) (x - 4)

Step-by-step explanation:

y2-y1 / x2-x1

-4 -(-3) / -5 - 4

Double negative switches the # to a positive

-4+3 / 5 - 4

= -1 / -9

Two negatives equal a positive

m=1/9

y-y1=m(x-x1)

y-(-3)=(1/9)(x-4)

Double negative=positive #

y+3=(1/9)(x-4)

Distribute (1/9) to the x and -4

y+3= (1/9)x - (4/9)

Subtract 3 from both sides

y = -3.4

It will take 300 minutes to fill the pool if only 3 taps are used

From the question, we have the following parameters that can be used in our solution:

Number of taps = 5 taps

Number of minutes = 180 minutes

From the above parameter, we can calculate the constant of proportionality

The constant of proportionality is calculated as

Constant of proportionality = Number of taps * Number of minutes

Substitute the known values in the above equation

So, we have the following equation

Constant of proportionality = 5 * 180

Evaluate the quotient

Constant of proportionality = 900

The number of minutes it will take to fill the pool is then calculated as

Constant of proportionality = Number of taps * Number of minutes

Where

Constant of proportionality = 900

Number of taps = 3

Substitute the known values in the above equation

So, we have the following equation

900 = 3 * Number of minutes

This gives

Number of minutes = 900/3

Evaluate

Number of minutes = 300

Hence, the number of minutes is 300 minutes

The equation is  1068.50 + 37.75 x =  1672.50 and the value of x is 16.

Members of our lacrosse team raised 1672.50 to go to a tournament.

Amount raised by lacrosse team = 1672.50

Let the number of players in lacrosse team = x

They rented a bus for 1068.50 and budgeted $37.75 per player for meals. So, mathematically this can be represented as

1068.50 + 37.75 x

Total amount paid by lacrosse team =  1068.50 + 37.75 x

As amount raised by lacrosse team and the amount paid by lacrosse team are equal so we can write

1068.50 + 37.75 x =  1672.50

37.75 x =  1672.50 - 1068.50

37.75 x =  604

x = 16

Thus, we can conclude that the value of x is 16 and the equation is 1068.50 + 37.75 x =  1672.50.

The sum of the two digits of Joey's age the next time his age is a multiple of Zoe's age is of 11, and this measure was found using a system of equations.

The variables for the system of equations in this problem are given as follows:

Joey is one year older than Chloe, hence:

x = y + 1.

Zoe is exactly one year old, hence:

z = 1.

The difference between the ages of Chloe's and Zoe's have 9 factors. Numbers with nine factors have the following format:

x² x y² , with different x and y.

These numbers have to be different of 1, due to Zoe's age, hence the smallest number is given as follows:

2² x 3² = 4 x 9 = 36.

There are 16 half-cup servings of beans and 4, three-ounce servings of shrimp.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represents number of half-cup servings of beans

Let y represents  number of 3 ounce servings of shrimp  

We have a system of equations, one for carbs and one for calories;

7x + 9y = 150

30x + 190y = 1400  

Now,

30(7x + 9y) = 30(150)  

-7(30x + 190y) = -7(1400  )  

210x + 270y = 4440  

-210x - 1330y = -8680

-1060y = -4240  

y = 4

Then substitute we get;

7x + 9y = 150

7x + 9(4) = 150

7x + 36 = 150

Answer:

B) y= 5x + 26

Step-by-step explanation:

if susie starts with 26 rocks and adds 5 rocks each month and x=months then the correct option is Option B

Answer:  y = 5x+26  (choice B)

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

Explanation:

The equation y = mx+b is in slope intercept form

m = slope

b = y intercept

The y intercept is the starting amount. In this case, she starts with b = 26 rocks. The m = 5 refers to the fact she adds 5 rocks per month. Each time x goes up by 1, y goes up by 5. Think of slope = rise/run = 5/1

rise = 5 = go up by 5 rocks

run = 1 = each time you go up by 1 month

The ratio of the volume of the large sphere to the volume

of the small sphere is 1226 .

V = 4/3 r³ is the equation to calculate a sphere's volume. The volume of a sphere is calculated using the following formula: 4/3rds of Pi and the cube of the sphere's radius. A sphere is a geometrical object that is a three-dimensional equivalent of a two-dimensional circle . A sphere is a collection of points in three-dimensional space that are all located at the same r distance from a particular point. The radius of the sphere is equal to r, and the provided point is its center. In the works of the ancient Greek mathematicians, spheres are first mentioned.

In several branches of mathematics, the sphere serves as a basic building block. Also found in nature and industry are spheres and nearly-spherical shapes.

Volume sphere = 4/3πr³

Volume of sphere 1

D = 4 inches

r = 2 inches

So,

Volume = 4/3π(2)³

= 33.51 inches³

Volume of sphere 2

D = 428 inches

r = 214 inches

So,

Volume = 4/3π(214)³

A solution of NaOH is a really strong base, so, when it's dissolved in water to form a solution, it dissociates completely in it's ions: and its

pH = 14.8344 and rounded it will be 14.8

it dissociates completely in it's ions:

NaOH -------> Na⁺ + OH⁻

So, to calculate the pH, we first need to calculate the OH concentration. As it was stated before, a strong base like this, it will dissociate completely so the concentration of OH will be the same concentration of NaOH:

[OH⁻] = 6.83 M

The pH is calculated with the following expression:

14 = pH + pOH

So, with the OH we can calculate the pOH, and then, the pH:

pOH = -log[OH⁻]

pOH = -log(6.83) = -0.8344

So the pH:

pH = 14 - pOH

pH = 14 - (-0.8344)

pH = 14.8344 and rounded it will be 14.8

There is not enough evidence to support the claim that women who exercise daily have a significantly different duration of labor than all women.

Standard error sm = 1.634

Test statistic t = 1.102

P-value = 0.28

This is a hypothesis test for the population mean.

The claim is that women who exercise daily have a significantly different duration of labor than all women.

Then, the null and alternative hypothesis are

[tex]H_{0}[/tex] : μ=16

[tex]H_{0}[/tex] : μ≠ 16

The significance level is 0.05.

The sample has a size n=29.

The sample mean is M=17.8.

As the standard deviation of the population is not known, we estimate it with the sample standard deviation, that has a value of s=√77.4=8.8.

The estimated standard error of the mean is computed using the formula:

[tex]s_{M}[/tex]   =   [tex]\frac{s}{\sqrt{n} }[/tex]   =   [tex]\frac{8.8}{\sqrt{29} }[/tex]=   1.634

Then, we can calculate the t-statistic as

t=(M-μ)/(s/[tex]\sqrt{n}[/tex])=(17.8-16)/1.634)=1.102

The degrees of freedom for this sample size are:

df=n-1=29-1=28

This test is a two-tailed test, with 28 degrees of freedom and t=1.102, so the P-value for this test is calculated as (using a t-table):

[tex]P_{value}[/tex]=2.P(t≥1.102)=0.28

As the P-value (0.28) is bigger than the significance level (0.05), the effect is not significant.

The null hypothesis failed to be rejected.

There is not enough evidence to support the claim that women who exercise daily have a significantly different duration of labor than all women

Step-by-step explanation:

The car' s worth after the end of third year will be $18100.

An asset loses value over time as a result of use, damage, or obsolescence. Depreciation is the measurement for this decline. Depreciation, or a decline in asset value, can be brought on by a variety of other variables, such as bad market conditions, etc. Depreciation is the estimated decrease in value of fixed assets over the course of a fiscal year. Large lump sum purchases are made for tangible things like real estate, machinery, vehicles, and so forth.

Given Data

An automobile purchased for $34,000 is worth $2200 after 6 years.

Annual depreciation = [tex]\frac{34000-2200}{6}[/tex]

Annual depreciation = [tex]\frac{31800}{6}[/tex]

Annual depreciation = 5300

In 3 years depreciation would be

= 5300(3)

= 15900

Thus the value after the end of third year will be:

34000 - 15900

18100

The car' s worth after the end of third year will be $18100.
