Answer:

C=60/h

Step-by-step explanation:

Cost is inversely Proportional to the number of friends who decides to host.

If five (5) friends host the party,

And each friend pays $12 for food and supplies

The equation that describes the relationship is

C=k ×1/h

Where,

C= cost that each host pays

K=constant

h=number of host

Therefore,

$12=k×1/5

$12=k/5

Make k the subject of the formula

$12=k*1/5

Multiply both sides by 5

12×5=k*1/5×5

60=k*5/5

60=k*1

60=k

Sub the value of k into

C=k ×1/h

C=60*1/h

C=60/h

Answer:

Answer:

This equation is for a linear graph.

y = mx + b, where m is the slope and b is the y-intercept. To graph this, plot a point at (0, 2), as that is your y-intercept.

As for the slope, always remember [tex]\frac{rise}{run\\}[/tex]. What this means is you first count up before counting horizontally for the slope. Your slope is 3/4, so from your y-intercept, count three numbers up, and four to the right (since the slope is positive). This second point should be at (4, 5)

Answer:

90 minutes

Step-by-step explanation:

Given that On day one, she runs for 20 minutes. On day two, she runs for 30 minutes. On day three, she runs for 40 minutes, this pattern may be presented as an arithmetic sequence shown below

20, 30, 40 ...

For an arithmetic sequence whose first term is a, and a common difference d, the nth term of the sequence may be given as

Tn = a + (n - 1)d

Hence the first term is 20, the common difference d is 10

On the 8th day, the 8th term

T8 = 20 + (8 - 1) 10

= 20 + 70

= 90 minutes

Final answer:

Emily will run for 90 minutes on day 8, calculated by applying the formula for the n-th term of an arithmetic sequence with a first term of 20 minutes and a common difference of 10 minutes.

Explanation:

Emily is training for a 10K race with a pattern of increasing her running time by 10 minutes each day. On day one, she runs for 20 minutes, on day two for 30 minutes, and on day three for 40 minutes. To calculate how many minutes she will run on day 8, we can observe this as an arithmetic sequence where the common difference is 10 minutes.

Using the formula for the nth term of an arithmetic sequence, which is an = a1 + (n-1)d, where:

We know that a1 is 20 minutes, d is 10 minutes, and n is 8 because we are looking for the time on day 8.

Therefore, a8 = 20 + (8-1)
10 = 20 + 70 = 90 minutes.

So, on day 8, Emily will run for 90 minutes.

The difference in length is 16,054 feet.

The difference in length between the alligator in the zoo and the longest alligator ever recorded in Florida is 16,054 feet.

To find the difference, you subtract the length of the alligator in the zoo from the length of the longest alligator recorded. So, 17,512 feet - 1,458 feet = 16,054 feet.

Answer:

The area of the rectangle in polynomial form is [tex]k^4 +10 k^2 + 21[/tex]

Step-by-step explanation:

Given

Shape: Rectangle

[tex]Height: k^2 + 3[/tex]

[tex]Width: k^2 + 7[/tex]

Required

Area of the rectangle

The area of a rectangle is calculated as thus;

[tex]Area = Length * Width[/tex]

By substituting [tex]k^2 + 3[/tex] for height and [tex]k^2 + 7[/tex] for width; This gives

[tex]Area = (k^2 + 3)(k^2 + 7)[/tex]

Expand the bracket

[tex]Area = k^2(k^2 + 7) + 3(k^2 + 7)[/tex]

Open each bracket

[tex]Area = k^2*k^2 + k^2*7 + 3*k^2 + 3*7[/tex]

[tex]Area = k^4 +7 k^2 + 3k^2 + 21[/tex]

[tex]Area = k^4 +10 k^2 + 21[/tex]

Hence, the area of the rectangle in polynomial form is [tex]k^4 +10 k^2 + 21[/tex]

Hope it will find you well

Final answer:

To find the area of composite figures, break them down into simpler shapes and sum up their areas. For three-dimensional figures, find individual surface areas and add them up.

Explanation:

Area can be determined by counting the number of squares inside a shape on 1 cm x 1 cm graph paper. For composite figures, break them down into simpler shapes, find their individual areas using appropriate formulas, then add them up. For three-dimensional composite figures, calculate surface area by finding the sum of individual surface areas of each component shape.

-1 is the slope

Step-by-step explanation:

to find the slope, you should find two different points on the line which is exactly on the grid. For example, (-2,0) and (-1,-1) is an ok choice. The formula for slope is y^2 - y^1 / x^2 - x^1 = slope

so it would look like -1-0 / -1-(-2)

Answer:

6.403 units

or [tex]\sqrt{41}[/tex]

Step-by-step explanation:

We want the hypotenuse.

The hypotenuse is from the point (-3, -1) to point  (2, 3)

D( (-3, -1), (2, 3)) = root ( (2 - (-3))^2 + (3 - -1)^2 ) =

D( (-3, -1), (2, 3)) = root ( 5^2 + 4^2)  =  root( 25 + 16)

D( (-3, -1), (2, 3)) = root ( 41)

D( (-3, -1), (2, 3)) = 6.403 units

Answer: 25+5m =50

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The actual number of companies that pay for advertising each month (25) plus the product of the companies added per month (5) and the number of months (m) must be equal to the actual number of advertisers multiplied by 2 ( since they want to double it ).

Mathematically speaking:

25 +5m = 25 (2)

25+5m =50

Feel free to ask for more if needed or if you did not understand something.  

Answer:

m=a/5

Step-by-step explanation:

From the statement, you have that the number of advertisers would be equal to the number of companies the daily gazzette has plus the 5 advertisers the newspaper wants to increase each month multiply for the number of months. From this, the expression would be:

2a=a+5m, where

a= number of advertisers

From this, we can isolate m:

5m=a

m=a/5

You can solve it to find the number of months it will take to double the advertisers:

m=25/5= 5

It will take 5 months as:

25+(5*5)= 25+25= 50

[tex]\dfrac{5}{y+5}[/tex]

Step-by-step explanation:

Here, we have to find the sum of 2 fractions:

1st fraction: [tex]\dfrac{3y}{y^{2}+7y+10}[/tex]

2nd fraction: [tex]\dfrac{2}{y+2}[/tex]

Considering the denominator of 1st fraction:

[tex]y^{2}+7y+10[/tex]

Using factorization method:

[tex]7y[/tex] can be written as [tex](2y + 5y)[/tex].

[tex]\Rightarrow y^{2}+2y+5y+10[/tex]

Taking 5 common from [tex]5y+10[/tex] and y common from [tex]y^{2}+2y[/tex]: [tex]\Rightarrow y(y+2)+5(y+2)[/tex]

Now taking [tex](y+2)[/tex] common:

[tex]\Rightarrow (y+5)(y+2)[/tex]

[tex]\dfrac{3y}{y^{2}+7y+10}[/tex] can be written as [tex]\dfrac{3y}{(y+5)(y+2)}[/tex]

Now, calculating the sum:

[tex]\dfrac{2y}{(y+5)(y+2)} + \dfrac{2}{y+2}[/tex]

Taking LCM and solving:

[tex]\Rightarrow \dfrac{3y+2(y+5)}{(y+5)(y+2)}\\\Rightarrow \dfrac{5y+10}{(y+5)(y+2)}\\\Rightarrow \dfrac{5(y+2)}{(y+5)(y+2)}\\\Rightarrow \dfrac{5}{(y+5)}[/tex]

Hence, answer is [tex]\dfrac{5}{y+5}[/tex].

Answer:

Ms. Davis is wrong

Step-by-step explanation:

she can make equal groups of 6

The equation that relates the mass of the object m and the length of the spring s is s = 0.3m, based on the given information that a 30-gram object stretches the spring 9 centimeters.

The direct variation between the mass of an object and the length of a spring can be described by the equation:

s = k × m, where s is the spring length, m is the mass of the object, and k is the constant of proportionality.

For a 30-gram object stretching the spring to 9 centimeters, the constant k can be found using:

k = s/m, which is k = 9 cm / 30 g, so k = 0.3 cm/g.

Therefore, the equation that relates the mass of the object m and the length of the spring s is s = 0.3m.

Answer:

His wife gets $1068 more than his son.

Step-by-step explanation:

Peter and Alex:

Peter gets [tex]\frac{4}{4+5} = \frac{4}{5}[/tex] of the total amount.

[tex]\frac{4*4450}{5} = 3560[/tex]

Peter gets $3560. He divides with his wife and son.

Peter gets [tex]\frac{1}{1+6+3} = \frac{1}{10}[/tex] of the amount, the wife gets [tex]\frac{6}{1+6+3} = \frac{6}{10}[/tex] and the son gets [tex]\frac{3}{1+6+3} = \frac{3}{10}[/tex]

Wife:

[tex]\frac{6*3560}{10} = 2136[/tex]

His wife gets $2136

Son:

[tex]\frac{3*3560}{10} = 1068[/tex]

How much more does his wife get over their son?

2136 - 1068 = 1068

His wife gets $1068 more than his son.
