At the market, 5 light bulbs cost $9. How much do 7 light bulbs cost?

Rudiy27

Hello!

To solve this, find the cost of a single light bulb first, by dividing 9 / 5.

9 / 5 ==> 1.80

One light bulb is $1.80

Now, multiply 1.80 by 7.

1.80 * 7 = 12.6

7 light bulbs cost $12.6

Hope this helps! ☺♥

I need some help please!

Answer:

8 seconds

Step-by-step explanation:

lets first start by plugging in 1024 into initial height

h(t) = -16t^2 + 1024

I would find a Greatest Common Factor (GCF) first

-16(t^2 - 64) If this is new just think that if you multiply -16 by t squared and -64 you will come back to the original equation

But now we notice that T squared -64 can be factored with the difference of perfect squared method

so we will get -16(t-8)(t+8)

So to get the answers we will set everything equal to 0

-16t =0

t =0 this is the time that the penny was thrown

t-8 = 0

t = 8 the is the time the penny hit the ground

t+8 =0

t= -8 This is an extraneous solution or a solution that doesn't make sense so we just disregard the solution.

Wich expression best estimates - 18 1/4 divided by 2 2/3

yKpoI14uk [10]

-18/3

18/(-3)

<h2>Explanation:</h2>

The complete question is as follows:

________________________________________________

Which expression best estimates -18 1/4 divided by 2 2/3?

18/3

-18/3

-18/(-3)

18/(-3)

________________________________________________

So in this exercise, we have two mixed fractions. This type of fractions comes from the combination of a whole number and a proper fraction fraction (numerator less than denominator). In order to solve this problem, we need to transform these mixed fractions into improper fractions (numerator greater than denominator). So:

$-18 \frac{1}{4}=-\left(18+\frac{1}{4}\right) \\ \\ Cross \ Multiplication\ -\left(\frac{18\times4+1}{4}\right) \\ \\ Solving \ numerator \ -\frac{72+1}{4} \\ \\ Simplifying \ -\frac{73}{4}$

$2 \frac{2}{3}=2+\frac{2}{3} \\ \\ Cross \ Multiplication\ \frac{2\times 3+2}{3} \\ \\ Solving \ numerator \ \frac{6+2}{3} \\ \\ Simplifying \ \frac{8}{3}$

By dividing:

$\frac{-\frac{73}{4}}{\frac{8}{3}} \\ \\ It's \ the \ same \ as: \\ \\ -\frac{73\times 3}{8\times 4}=-\frac{219}{32} \approx -6.84$

<em>So the expressions that best estimates -18 1/4 divided by 2 2/3 are:</em>

<em>Whose value in decimal form is -6.0</em>
