Answer:

B- 3/10

Step-by-step explanation:

9/14 x 7/15

multiply across so you would now get 63/210 and we can divide the top and bottom by 21 so it will simplify to 3/10

The manager at Gabriela's Furniture Store is trying to figure out how much to charge for a book shelf that just arrived. The boo

tatuchka [14]

Answer:

Step-by-step explanation:

The book shelf arrived at the wholesale price = $ 147

Mark up on the furniture = 60 %

So The Cost Price = $147

Markup = 60% = 0.60

So using the formula

Sale Price = Cost Price + Cost Price * Markup percentage

Sale Price = 147 + 147*(0.60)

Sale Price = $ 235.20

Find the sides of a triangle if two of its sides are equal, the third side is 1 1/3 cm longer than the others, and its perimeter

denis-greek [22]

Answer:

Length oh two equal sides: 1 16/45 cm

Third side: 2 31/45 cm

Step-by-step explanation:

length of two equal sides is x

Perimeter = x + x + ( x + 1 1/3) = 3x + 1 1/3 = 5 2/5

3x = 5 2/5 - 1 1/3 = 27/5 - 4/3 = 61/15

x = 61/45 = 1 16/45

Third side = 61/45 + 4/3 = 121/45 = 2 31/45

Ann [662]

Corrected Question

In the year 2009, the cost of a flat screen television can be modeled by the equation C = -10t^2 + 500 where t is the number of years since 2009. Factor this cost polynomial.

Answer:

$C=10(50-t^2)$

Using express exponents, you write C=10(50-t^2)

Step-by-step explanation:

To factor the cost polynomial, $C=-10t^2+500$ , we follow these steps.

Step 1: Determine the greatest common divisor of the terms in the polynomial

The terms in the polynomial are $-10t^2$ and 500$

The greatest common divisor of $-10t^2$ and 500$ is 10.

Step 2: Factor the polynomial by dividing each of the terms with the greatest common divisor obtained above.

$C=10\left(\dfrac{-10t^2}{10} +\dfrac{500}{10}\right)\\C=10(-t^2+50)\\$We can rewrite this as \\C=10(50-t^2)$
