Answer:

t=40.5

Step-by-step explanation:

T likely stands for time. but I suspect you haven't given us the full question because the piece you gave us doesn't determine what T stands for. either way, t is your variable. could be substituted for x or any other variable.

t2=81

isolate t

/2

t= 81/2

t= 40.5

This is multiplying fractions and i have to show work
grandymaker [24]

To solve:

\frac{2}{3}\times(-4\frac{1}{3})

Let us convert the mixed fraction into fraction first,

\frac{2}{3}\times(-\frac{13}{3})

On simplification we get,

-\frac{26}{9}

Hence, the answer is,

-\frac{26}{9}

(2x+3)(4x-1)<8x^(2)+1
Sidana [21]

Answer: x

Step-by-step explanation:

(2x+3)(4x-1)

Begin by multiplying parentheses.

(2x*4x)+(2x*-1)+(3*4x)+(3*-1)

(8x^2)+(-2x)+(12x)+(-3)

8x^2-2x+12x-3

Subtract 8x^2

8x^2-2x+12x-3+(-8x^2)

-2x+12x-3

Add 3

-2x+12x-3+3

-2x+12x

Combine like terms;

10x

Divide by 10

x

Simplify;

x

The table shows the number of toys sold at Penelope's Toys and Games store in different years. Find the rate of change in the nu
Aliun [14]

Answer:

Year - (1993 - 1995)

Step-by-step explanation:

Rate of change in the number of toys sold = \frac{\text{change in number of toys sold}}{\text{Time interval}}

In the interval (1990 - 1993),

Rate of change in number of toys sold = \frac{32000-20000}{1993-1990}

                                                                = \frac{12000}{3}

                                                                = 4000

In the interval (1993 - 1995),

Rate of change = \frac{42000-32000}{1995-1993}

                          = \frac{10000}{2}

                          = 5000

In the interval (2000 - 1995),

Rate of change = \frac{57000-42000}{2000-1995}

                          = \frac{15000}{5}

                          = 3000

In the interval (2006 - 2000),

Rate of change = \frac{63000-57000}{2006-2000}

                          = \frac{6000}{6}

                          = 1000

Therefore, rate of change in the number of toys sold is greatest in the interval (1993 - 1995).
