How much do 777 light bulbs cost?

Answers

Question:

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

Answer:

Cost of 7 bulbs is $ 12.6

Solution:

Given that,

5 light bulbs cost $ 9

Find the cost of 1 bulb

Cost of 1 bulb is found by dividing the cost of 5 bulbs by 5

$cost\ of\ 1\ bulb = \frac{\text{cost of 5 bulbs}}{5}\n\ncost\ of\ 1\ bulb = (9)/(5)\n\ncost\ of\ 1\ bulb = 1.8$

Thus cost of 1 bulb is $ 1.8

Find the cost of 7 bulbs:

$cost\ of\ 7\ bulbs = 7 * \text{cost of 1 bulb }\n\ncost\ of\ 7\ bulbs = 7 * 1.8\n\ncost\ of\ 7\ bulbs = 12.6$

Thus cost of 7 bulbs is $ 12.6

Answer:

7 bulbs equals 12.6

In a 10 times 10 grid that represents 800 one square represents

Answers

800/10 = 80
80/10 = 8

8 x 10 = 80
80 x 10 = 800

one square represents 8

Solve:-

800 ÷ 10 = 80
80 ÷ 10 = 8

So, this shows that each square represents 8.

ALGEBRA! NEED HELP! ~Write a formula for the total surface area of a cube in terms of its edge length x. Explain your reasoning.

Answers

Since each edge's length is x, each face's are would be ${ x }^( 2 )$
And cubes have 6 faces. multiply 6 by ${ x }^( 2 )$ , the formula is : $6{ x }^( 2 )$

surface area of a cube
cube=6 squares
square=2 equal sides
area of square=side^2
surface area of cube=6(area of square)=6side^2
side=x
SA=6x^2

Can you solve this:
JUST number 7 and 8
Thanks everyone

Answers

for number 7 because 9 is the number of small triangle and 99 is for the bigger one so you can say 9 * 11 = 99 so 10 * 11 = 110 = x
and for number 8 because the small triangle has the same sides so the bigger one should have too so x = 100 :)))
hope this is helpful
have a nice day
