Answer:

answers are highlighted below! I hope this helps! please do not copy my work! ^-^ :)

Step-by-step explanation:

okay, on the first one we are told we have 15% off of $729.99

which then takes off about $109.50

after we subtract the $109.50 from the $729.99 we are left with $620.49, that's not including tax

sales ax is 8.25% or $51.19 that comes out to equal $671.69

so we can conclude that the big tv sale at the big box store is equal to the amount of $671.69

on the second one, its normally $699.99

we have the coupon for $100 off of that price so that leaves us with $599.99

but we have the $50 charge for delivery. so now its at $649.99

now we need to determine the price after tax. the price of tax is $53.62

add the tax amount to $649.99 to get $703.61

$703.61

the initial price of the tv is $734.95

$150 in rebate (refund)

$734.95 - $150 = $584.95

now we need to find the price including the delivery cost

$584.95 + $35 = $619.95

now lets find the tax price

$51.15

After Tax Price: $671.10

The TV from the Electronic Warehouse is the best option. You pay only $671.10! The prices from the two other stores are $703.61 and $671.69.

We are paying .59 cents less than one of the TV's, and we are also paying $32.51 less than the other TV! So the best option would be the TV from the Big Box store!

A recipe calls for 1 part beans to 1½ parts rice. if 1½ parts of beans are used, how much rice should be used?

riadik2000 [5.3K]

$1 \text{ part beans} \longrightarrow 1\dfrac{1}{2} \text{ parts rice}$

$1 \dfrac{1}{2} \text{ part beans} \longrightarrow 1\dfrac{1}{2} \times 1 \dfrac{1}{2} \text{ parts rice}$

$1 \dfrac{1}{2} \text{ part beans} \longrightarrow \dfrac{3}{2} \times \dfrac{3}{2} \text{ parts rice}$

$1 \dfrac{1}{2} \text{ part beans} \longrightarrow \dfrac{9}{4} \text{ parts rice}$

$1 \dfrac{1}{2} \text{ part beans} \longrightarrow 2\dfrac{1}{4} \text{ parts rice}$

determining the number of roots of the equation 8x^3+12x^2-50x+135=0 and find also the interval(s) that isolate the roots.Are th

professor190 [17]

Answer:

one negative real root in [-5, -4]; two complex roots
the complex roots cannot be isolated in the same way.

Step-by-step explanation:

A graphing calculator is a wonderful tool for this. It shows the one real root to be near -4.062, so between -5 and -4.

The value of the cubic at x = -5 is -315; at -4 it is +15, so the root is definitely between those values.

The one real root is isolated to being between (-5, -315) and (-4, 15). The complex roots are not isolated.
