Answer:

s = -5

Step-by-step explanation:

solve for s

-50 = 10s

divide both sides by 10

-50 / 10 = -5

10s/10 = s

we're left with s = -5

The number of years it will take for Yasemin's account balance to reach $1500 is 13.52 years.

Step-by-step explanation:

Where the model of the relationship between the time, t, in years, since the account was first opened and the and the balance in Yasemin's account is presented as follows;

$B(t) = 1000 \times e^{(0.03 \times t)}$

To find find out how many years it will take for Yasemin's account balance to reach $1500, we substitute B(t) = $1500 since we are told that after the years his account balance became $1500 as follows;

$\$ 1500 = 1000 \times e^{(0.03 \times t)}$

We now solve for t

$\$ 1500 = 1000 \times e^{(0.03 \times t)}\\\\\frac{1500 }{1000 } = e^{(0.03 \times t)}\\1.5 = e^{(0.03 \times t)}\\\\ln(1.5) = ln (e^{(0.03 \times t)})\\\\ln(1.5) = (0.03 \times t) \times ln (e)\\\\\therefore ln(1.5) = (0.03 \times t) \\\\t = \frac{ln(1.5)}{0.03 } = 13.52 \ years$

The number of years it will take for Yasemin's account balance to reach $1500 = 13.52 years.

wariber [46]

Answer:

4 square feet

Step-by-step explanation:

We can use Ratio to solve this question

It takes 15 minutes to paint 60 square feet

This is written as:

15:60

Divide both sides by 15

1:4

Therefore it takes Painter Paul 1 minute to paint 4 square feet

Which of the following equations have infinitely many solutions?

Svetllana [295]

Answer:

Choice A

Step-by-step explanation:

In each case, each equation has an equation of a line in y = mx + b form equaling another equation of a line in y = mx + b form. If the two sides are equal, it is the same equation, there are infinitely many solutions. If the sides are different, then if the slopes are different, the lines intersect at one point, and there is exactly 1 solution. If the slopes are equal, the lines are parallel, and there is no solution.

(Choice A) -10x-10=-10x-10

In Choice A, both sides of the equation are equal, so there are infinitely many solutions.

(Choice B) 10x-10=-10x+10

(Choice C) 10x-10=-10x-10

(Choice D) -10x-10=-10x+10

In choices B through D, the two sides are not equal, so there is either 1 solution (B and C since they have different slopes) or no solution (D since the slopes are equal).
