Answers
Answer:
2/3
Step-by-step explanation:
Let n = the repeating, non-terminating number 0.666...
We now have n = 0.666666...
We want the number n in the form of a fraction.
Since only 1 digit repeats, the 6, use a 1 followed by 1 zero, which means the number 10. Now multiply both sides by 10 and write the original equation below it.
10n = 6.666666...
n = 0.666666...
Subtract the bottom equation from the top equation.
9n = 6
n = 6/9
n = 2/3

1)A fish tank has a volume of 520 in. it is emptied at a constant rate of 10 cubic inches every minute. Which equation represents the volume v,after t, time in minutes
Answers
Answer:
v=520 -10t
Step-by-step explanation:
the rate of decrease is given a variable to calculate the rate of change. v is represented by 520 - the number of minutes.
V = 520 - 10t is the representation of the decrement of the volume of the fish tank.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Given that volume of fish tank = 520 inch³
Now since volume is decreasing at a rate of 10 inche³/minute
Decrement of t minutes = 10t
So,
New volume = Original volume - decrement of t minutes
V = 520 - 10t
Hence "v = 520 - 10t is the representation of the decrement of the volume of the fish tank".

Approximately 220 million tires are discarded in the U.S. each year. These tires present a disposal problem because they take up space, harbor pests, and have been known to catch fire. One tire can generate about 250,000 BTUs (1 BTU = 3 x 10-4 kWh) when it is burned. The average American home consumes about 10,000 kWh of electricity per year. How many tires would be needed to meet the annual electricity demand of ten homes for one year if the production of electricity from tires is 50% efficient?
Answers
Answer:
2667 tires
Step-by-step explanation:
One tire can generate:
250000 BTU's = 250000*3*10⁻⁴ kWh = 75 kWh electricityConsidering efficiency of 50%, one tire can produce:

gain 3, lose 2, lose 1, gain 1, gain 2. On what yard line did the Wildcats end? *

$ 54.05
The change in price stock is $54.05.
How to calculate change in any quantity?First: work out the difference (increase or decrease) between the two numbers you are comparing.
Increase or decrease = New Number - Original Number.
initial price= $99.24
final price= $45.19
So, Change in stock = final price- initial price
=$45.19 - $99.24
=-$54.05

Answer:
From the given diagram, the measurement of ∠RQS is 106° and the measurement of ∠TQS is 74°
Step-by-step explanation:
For this problem, we are to find the measurements of ∠RQS and ∠TQS which makes up the straight line RQT. Straight lines have a measurement of 180°. So, since ∠RQS and ∠TQS make up ∠RQT, then we are goingt o set up an equation where we add ∠RQS and ∠TQS together and equal them to ∠RQT.
m∠RQS + m∠TQS = m∠RQT
Now, let's fill the information from the problem into our equation.
(11x + 7) + (8x + 2) = 180
Combine like terms on the left side of the equation.
19x + 9 = 180
Subtract 9 form both sides of the equation.
19x = 171
Divide by 19 on both sides of the equation.
x = 9
So, we know the value of x is 9. Now, let's plug in this value into each angle so we can see the measurements of each.
m∠RQS = 11(9) + 7 = 99 + 7 = 106°
m∠TQS = 8(9) + 2 = 72 + 2 = 74°

Diameter= 180cm
Circumference of each table

Each table can fit
= 180π ÷70
= 8 guests (nearest whole number)
Since there are 18 tables, total number of guests
= 8(18)
= 144 guests
Since there are only enough tables to sit 144 guests, there are not enough tables to fit 145 guests.
Note that we cannot take the sum of the circumference for 18 tables than divide by 70 to see how many guests can fit because a guest can only be sitted on one table.
If that was done,
Total circumference
= 180π(18)
= 10179 cm (5 s.f.)
Total number of people
= 10179 ÷70
= 145 people (3 s.f.)
