Answer:

5 weeks

Step-by-step explanation:

Let x represent the number of weeks they have been saving

Create an equation that sets Cameron and Sams' savings equal to each other, then solve for x

4x + 20 = x + 35

3x + 20 = 35

3x = 15

x = 5

So, they will have saved the same amount of money after 5 weeks

iogann1982 [59]

Answer:

$1529.8

Step-by-step explanation:

Given:

Tammy has a job that has a weekly salary of $1,200.

But wants to switch a job that has a monthly salary of $11,700

Question asked:

How much more will she make per week if she switch to the new job?

Solution:

Monthly salary of a new job, she wants to switch = $11,700

Weekly salary of a new job, she wants to switch = ?

As we know : 1 month = 4.286 Weeks

Salary of 1 month for a new job, she wants to switch = $11,700

Salary of 4.286 Weeks for a new job, she wants to switch = $11,700

Salary of 1 Week for a new job, she wants to switch = $11700\div4.286=\$2729.81$

Now, we have to find that How much more she will make per week, if she switch to the new job.

More money she will make for a new job she wants o switch = Weekly salary for a new job, she wants to switch - Weekly salary of current job

More money she will make, for a new job = $2729.8 - $1200 = $1529.8

Therefore, she will make $1529.8 more per week if she switch to the new job.

If y= -3x7+2x3+ x, the derivative of y with respect to x is

larisa [96]

Answer:

$\frac{dy}{dx}$ = - 21 $x^{6}$ + 6x² + 1

Step-by-step explanation:

Differentiate each term using the power rule

$\frac{d}{dx}$ (a $x^{n}$ ) = na $x^{n-1}$

Given

y = - 3 $x^{7}$ + 2x³ + x , then

$\frac{dy}{dx}$ = (7 × - 3 ) $x^{6}$ + (3 × 2)x² + (1 × 1 ) $x^{0}$

= - 21 $x^{6}$ + 6x² + 1

The question is............

irina1246 [14]

A(n,s)=(ns^2)/(4tan(180/n)), n=number of sides, s=side length

A(8,4.6)=(8*4.6^2)/(4tan22.5)

A(8,4.6)=42.32/tan22.5 m (exact)

A(8, 4.6)≈102.17 m^2 (to nearest hundredth of a square meter)

Step-by-step explanation:

From the question, we are told that the temperature at 6:00 am was -12 Fahrenheit and that the temperature increased by 1/2 Fahrenheit each hour for 6 hours.

The temperature, in degrees Fahrenheit, at noon would be:

= -12°F + 1/2(6)

= -12°F + 3°F
