Answer:

5.65%

Step-by-step explanation:

Principal=$600

Time=20 years

FV=600*3=$1800

n=1

r=?

r= n[(A/P)^1/nt - 1]

=1{(1800/600)^ 1/1*20 - 1}

={(3)^1/20-1}

=3^0.05-1

=1.0565-1

=0.0565

rate=0.0565*100

=5.65% to the nearest hundredth percent

Vitek1552 [10]

Required Equation is y = \frac{2x}{3}+2

Given: A line passing through ({x}_1,{y}_1) and ({x}_2,{y}_2)

Slope = \frac{(y_2 - y_1)}{(x_2 - x_1)} = \frac{( 1 - (-1))}{(3 - 0)}= \frac{2}{3}

Equation of line is:

Y_1(x) = \frac{2}{3}x + b

Where b is y intercept

for value of b

Y_1(0) = -1 = \frac{2}{3}*0 + b = b

⇒ b = -1

and Equation of line is:

Y_1(x) = \frac{2}{3}x + (-1)

For another parallel line that passes through the point (-3,0)

Y_2(x)= \frac{2}{3}x + c

Y_2(-3) = 0 = {2}{3}*-3 + c = -2 + c = 0

c = 2

then the equation is:

Y_2(x) = \frac{2}{3}x + 2

Solving 8 problems per minute, Fast Finn can finish his test in time. He was however, working faster, solving 10 problems per mi
mrs_skeptik [129]

Answer:

Number of problems = 240

Step-by-step explanation:

Let x be the number of questions and t be the time.

Given:

Average rate = 8 problems per minute

Fast Finn rate = 10 problems per minute

Fast Finn taken time = t - 6

We need to find the number of problems on the test paper.

Solution:

Average rate to solve test paper.

Average\ rate =\frac{Number\ of\ questions}{time}  

8 =\frac{x}{t}

t =\frac{x}{8} --------------(1)

Fast Finn rate to solve the test paper.

Average\ rate =\frac{Number\ of\ questions}{time}  

10 =\frac{x}{t-6}

Using cross multiplication rule.

x=10(t-6)

x=10t-60

substitute t =\frac{x}{8}  from equation 1.

x=10(\frac{x}{8}) -60

Rearrange the equation as:

x - \frac{5}{4}x = -60

\frac{4x-5x}{4}=-60

-\frac{x}{4} =  -60

Using cross multiplication rule.

x = 60\times 4

x = 240 problems.

Therefore, 240 problems were on the test.
