The total earnings with fees this week will be $571.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

Takira is an arrangement setter for a deals association. She makes $12 an hour in addition to a $3 charge for every arrangement that is planned.

Let 'x' be the number of hours and 'y' be the number of appointments. Then the equation is given as,

Total earnings = $12x + $3y

This week. Takira worked 40 hours and scheduled 31 appointments. Then the total earnings are calculated as,

Total earnings = $12(40) + $3(31)

Total earnings = $480 + $91

Total earnings = $571

The total earnings with fees this week will be $571.

Answer:

They have 5 packages of pancake mix.

N(p) = 140*p

Represents the number of people that can be feed with p = # of packages of pancake mix used.

Now, the domain will be the set of the possible values of p that we can use here.

the set of possible values of p will be:

{0, 1, 2, 3, 4, 5}

We can not use more than 5 because there are only 5 packages.

But we can use actually half a package or a third, so we not should use only whole numbers in the domain, then the domain can be written as:

D = 0 ≤ p ≤ 5

Now, the range is the set of the possible values of N(p)

The minimum will be when p = 0.

N(0) = 140*0 = 0

The maximum will be when p = 5

N(5) = 140*5 = 700

Then the range can be written as:

R = 0 ≤ N ≤ 700

Here we could add another restriction, because we can only feed a whole number of people, then we also should add the restriction that N must be a whole number:

R = 0 ≤ N ≤ 700, N ∈ Z

Answer:

(p+3)(p-7) = 0

Step-by-step explanation:

Given p=x^2+6p and (x^2+6)^2-21=4x^2+24

We are to substitute the the p = x²+6 into the expression as shown;

The expression (x^2+6)^2-21=4x^2+24 will become

(x²+6)²-21 = 4(x²+6)

On substituting p, the expression becomes;

p²-21 = 4p

Subtract 4p from both sides

p²-21-4p = 4p-4p

p²-4p-21 = 0

p²-7p+3p-21 = 0

p(p-7)+3(p-7) = 0

(p+3)(p-7) = 0

Hence the expression in terms of p is (p+3)(p-7) = 0

Answer:

100

Step-by-step explanation:

M = log(I/S)

The intensity of the first earthquake:

8 = log(I₁/S)

10⁸ = I₁/S

I₁ = 10⁸ S

The intensity of the second earthquake:

6 = log(I₂/S)

10⁶ = I₂/S

I₂ = 10⁶ S

The ratio is:

I₁/I₂ = (10⁸ S) / (10⁶ S)

I₁/I₂ = 100

It is 100 times stronger.

An earthquake with a magnitude of 8 is 100 times stronger than an earthquake with a magnitude of 6.

Given the following data:

To determine how many times stronger is an earthquake with a magnitude of 8 than an earthquake with a magnitude of 6:

Mathematically, the magnitude of an earthquake is given by the formula:

[tex]Magnitude = Log(\frac{I}{S} )[/tex]

Where:

For earthquake A:

[tex]8=Log (\frac{I_A}{S} )\\\\10^8=\frac{I_A}{S}\\\\I_A=S10^8[/tex]

For earthquake B:

[tex]6=Log (\frac{I_B}{S} )\\\\10^6=\frac{I_B}{S}\\\\I_B=S10^6[/tex]

For strength:

[tex]Strength = \frac{I_A}{I_B} \\\\Strength = \frac{S10^8}{S10^6} \\\\Strength = 10^2[/tex]

Strength = 100

Answer:

4.15 hours

Step-by-step explanation:

Answer:

4.074 hours

Step-by-step explanation:

r =

The formula for speed = Distance × Time

Hence,

Let the outbound speed = r

return trip speed = r + 25x/100 = 125r/100 = 1.25r

Note that: 9 hours and 20 minutes = 9.167

Let t1 and t2 be the time taken to travel on way and return journey.

t1 + t2 = 9 hr 10 min = 9.167 hrs

Hence:

2688/r + 2688/1.25r = 9.167

LCM(1.25r)

(2688 × 1.25) + 2688 /1.25r= 9.167

3360 + 2688 = 9.167 × 1.25r

6048 = 11.45875r

r = 6048/11.45875

Outbound trip rl = 527.8062615904876mph

Return trip speed = r + 25x/100 = 125r/100 = 1.25r

= 1.25 ×

659.75782699mph

Time for return trip = Distance/Speed

= 2,688 miles/659.75782699mph/

= 4.0742222222 hours

Approximately = 4.074 hours

Answer:

Step-by-step explanation:

(9,3) (0,12)

(x1,y1) (x2,y2)

to find the slope, use this equation:

y2-y1/x2-x1

12-3/0-9

the slope is 9/-9 = -1

Answer:

4 Hours

Step-by-step explanation:

Since the equation is:

y = 9x + 16

You have to find x

This is the logical way:

52-16 = 36 because thats the starting fee

So 36 divided by 9 equals 4

You do that because 9 is the charge per hr

So he rented it for 4 hours.
