Up to this point, the only types of numbers you've seen have been rational numbers. You can write any rational number as a fraction. The prefix ir- means not. What do you think it means for a number to be irrational? Can you think of any numbers that are irrational?

Answer:

Her investment will grow over the years due to the 2 percent interest. Inflation will impact the value of her investment

For the given data. the simple interest will be $100.His investment will grow over the years. Because of the simple interest.

It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.

It is given that, Pardis recently deposited $5,000 in a savings account that pays a return of 2 percent per year.

Principal = $5,000

Rate= 2%

Time= 1 year

SI = (P×R×T)/100

SI = (5000×2×1)/100

SI=100

Thus, for the given data. the simple interest will be $100.His investment will grow over the years. Because of the simple interest.

Answer:

243 and 394

Step-by-step explanation:

f(x) is the exponential as its values increase by 3 every hour, then

when x = 5

f(5 ) = 81 × 3 = 243

---------------------------

g(x) is linear as there is a common difference between consecutive values of + 3 , then

when x = 5

g(x) = 391 + 3 = 394

Answer:

x=180-95-57 (sum of triangle)

or,x=28

Step-by-step explanation:

Answer:

x = 27

Step-by-step explanation:

solving similarities using equations:

→[tex]\frac{CD}{QD} = \frac{RD}{BD}[/tex]

→ [tex]\frac{x}{39} = \frac{18+x}{26+39}[/tex]

→ [tex]\frac{x}{39} = \frac{18+x}{65}[/tex]

→ 65(x) = 39(18+x)

→ 65x = 702 + 39x

→ 65x - 39x = 702

→ 26x = 702

→ x = 27

Answer:

the correct answer is 8:9 or C.

Answer:

50,000

Step-by-step explanation:

1st car had $1,750 tax

2nd car has $3,500 tax

1750(2) = 3500

so your tax doubled so the price must be doubled.

The car is $50,000

Algebraically using direct variation:

t = kp    where t=tax, p = purchase price, 

             and k is constant of variation

1750 = 25000k

k = 1750/25000

k = 0.07

Your equation is:  t = 0.07p

3500 = 0.07p

p = 3500/0.07

p = $50,000

Answer:

  5 units

Step-by-step explanation:

The two points have the same y-coordinate so are on a horizontal line. The distance between them is the difference of their x-coordinates:

  2.5 -(-2.5) = 2.5 +2.5 = 5.0

The distance between the points is 5 units.

I assume "first phase" refers to the first 6.00 seconds of the dash.

Since the sprinter starts from rest and accelerates uniformly, he covers a distance x after time t of

x = 1/2 at²

where a is his acceleration.

The sprinter's velocity v after time t is

v = at

so that if he attains a speed of 14.7 m/s after 6.00 s, he does so with acceleration a such that

14.7 m/s = a (6.00 s)   ⇒   a = 2.45 m/s²

Then in the first 6.00 seconds, the sprinter travels

x = 1/2 (2.45 m/s²) (6.00 s)² = 44.1 m

Okay so, to solve these problems what you're gonna want to do is substitute the given x and y values into the equation.

For example, number 7.

11(d-c) + 3(c+d), when c=6, d=9

if d=9, you will substitute the d in the problem to 9.

11(9-c) + 3(c+9)

if c=6 you will substitute c for 6.

11(9-6) + 3(6+9)

You can solve now that you have a simpler problem to work with.

11(9-6) + 3(6+9) first...

11(9-6)  11*9=99   11*-6=-66, so, 11(9-6)= 99-66= 33.

3(6+9) 3*6=18 3*9=27 18+27=45

33+45=78

Your answer for number 7 is 78.

Hope this helps, just do the same for the other problems like this one.

Answer:

x = [tex]\frac{1-by}{y-a}[/tex]

Step-by-step explanation:

y = [tex]\frac{ax+1}{x+b}[/tex] ← multiply both sides by (x + b)

y(x + b) = ax + 1 ← distribute parenthesis on left side by y

yx + by = ax + 1 ( subtract ax from both sides )

yx - ax + by = 1 ( subtract by from both sides )

yx - ax = 1 - by ( factor x out of each term on the left side )

x(y - a) = 1 - by ← divide both sides by (y - a)

x = [tex]\frac{1-by}{y-a}[/tex]

Answer:

Step-by-step explanation:

1.  Eliminate fractions by multiplying both sides of this equation by x + b:

                                                                   y(x + b) = ax + 1

2.  Perform the indicated multiplication:   xy + yb = ax + 1

3.  Group together the x-terms                  xy - ax = 1 - yb, or x(y - a) = 1 - yb

                                                                               1 - yb

4.  Divide both sides by (y - a):                    x = ----------------

                                                                                  y - a

Answer:

1/3

Step-by-step explanation:

[tex]\frac{6}{9}*\frac{1}{2}[/tex]

[tex]\frac{6*1}{9*2}[/tex]

[tex]=\frac{6}{18}[/tex]

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(6,18) = 6

[tex]\frac{6/6}{18/6}=\frac{1}{3}[/tex]

Therefore:

[tex]\frac{6}{9}*\frac{1}{2}=\frac{1}{3}[/tex]

The other quantity needed to calculate the average speed is time.

Average speed is the total distance travelled per time. It is how fast an object moves with respect to time.

Average speed = total distance / total time

For example, if the distance travelled is 100km and the total time is 10 hours, average speed is 10 km/hr (100 / 10).
