EMERGENCY HELP! A steady stream of water flows into a partially-filled rectangular tank. After 6 minutes, there are 87 gallons of water in the tank. After 21 minutes, there are 222 gallons. Write an equation to represent the volume of water in the tank y after x minutes. How much water was in the tank to begin?
Answers
Answer:
[tex]y=9x+33[/tex]
33 gallons of water to begin with.
Step-by-step explanation:
So, we are essentially given two coordinates: (6,87) and (21,222). To find an equation, we will need to find the slope and y-intercept. We know it's a linear equation because it's a steady stream, meaning a constant slope.
Using the slope formula, the slope is:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}=\frac{222-87}{21-6}=135/15=9[/tex]
So, the rate at which the stream flows is 9 gallons per minute.
Now, let's find the initial amount of water. To do this, we can use point-slope form. Pick either of the two points. I'm going to use (6,87).
Point-slope form is given by:
[tex]y-y_1=m(x-x_1)[/tex]
Substitute:
[tex]y-(87)=9(x-(6))[/tex]
Distribute:
[tex]y-87=9x-54[/tex]
Therefore:
[tex]y=9x+33[/tex]
So, there were 33 gallons of water in the tank to begin with.

PLEASE HELP NOW --- >N is a 2-digit even number. If the last two digits of N^2 is the same as N, what is the sum of digits of N?
Answers
Answer:
76.
Step-by-step explanation:
It is given that N is a 2-digit number.
Last two digits of N^2 is the same as N.
We know that, a number is even if it ends with 0,2,4,6,8.
[tex]2^2=4,4^2=16,6^2=36,8^2=64[/tex]
If 0 is in end then we get two zeros in the square of that number.
It is clear that, number should ends with 6 to get the same number at the end.
[tex]16^2=256[/tex]
[tex]26^2=676[/tex]
[tex]36^2=1296[/tex]
[tex]46^2=2116[/tex]
[tex]56^2=3136[/tex]
[tex]66^2=4356[/tex]
[tex]76^2=5776[/tex]
[tex]86^2=7396[/tex]
[tex]96^2=9216[/tex]
It is clear that last two digits of (76)^2 is the same as 76.
Therefore, the required number is 76.
Which is the mean for this data? 1,2,5,5,6,6,7,8
Answers
Answer:

Step-by-step explanation:
First you need to add all the digits so 1 +2+5+5+6+6+7+8 = 40
Then, divide that by the number of digits which is 8.
Therefore, 40/8 = 5, which is the answer.

A zookeeper weighed an African elephant to be 9 × 103 pounds and an African lion to be 4 × 102 pounds. How many times greater is the weight of the elephant than the weight of the lion? A. 2.25x 10 B. 5 C. 13x10 D. 3.6x10
Answers
Answer:
2.25 x 10
Step-by-step explanation:
In the above question, we were given :
The weight of the Elephant = 9 × 10³ pounds
The weight of the African Lion = 4 × 10² pounds
We would compare both weights to determine which size is bigger
Weight of Elephant : Weight of Lion
9× 10³ : 4 × 10²
= 9 × 10³/4 × 10²
= 2.25 × 10¹
= 2.25 × 10
The weight of the elephant is 2.25 × 10 times greater than the weight of the lion.

This problem makes use of Cross Multiplying.
Simply do:
2x*3y=9*8
6xy=9*8
6xy=72
xy=12
Hope it helps <3
Explanation:
9/2x = 3y/8
2x • 3y = 8 x 9
2x • 3y = 72
3y = 72/2x = 36/x
y = 36/x • 1/3
y = 36/3x
y = 12/x
Plug y = 12/x in our equation:
9/2x = 3(12/x)/8
9/2x = 36/x/8
2x • 36/x = 9 x 8 (cross multiply)
36x = 72
x = 72/36 = 2
Plug x = 2 in the same to find y
9/2(2) = 3y/8
9/4 = 3y/8
3y x 4 = 72
3y = 72/4 = 18
y = 18/3 = 6

The middle ring will then have an area of π[tex]2^2[/tex] - π = π * 4 - π = 4π - π = 3π.
The largest ring will then have an area of π[tex]3^{2}[/tex] - π[tex]2^{2}[/tex] = 9π - 4π = 5π.
5π + 3π + π = 9π

C. y = -2(x - 4)
y = -2x + 8 incorrect
D. y = -(-2x+8)
y = 2x - 8 incorrect
y = -2x - 8 and y = -(2x + 8) when graphed are the same, they intersect at infinite points and there are infinite solutions.

90% of households in a certain region have answering machines. 50% of the
households have both an answering machine and call-waiting. A household chosen at random was found to have the answering machine.
What is the probability that it also has call-waiting?
Answers
As an approximate decimal, this is 0.5556 which converts to 55.56%
======================================================
Explanation:
Let's say there are 100 households (just for the sake of simplicity). We are told that 90% of them have answering machines. So that means 90 households have answering machines. In addition, 50 households have answering machines and call waiting. Those 50 households are part of the 90 mentioned previously.
We then select a house at random. Someone tells us (or we have some kind of prior knowledge) that whichever house is selected, they have an answering machine. We can ignore the 10 households that don't have an answering machine. Out of those 90 households, 50 have both features. So 50/90 = 5/9 is the probability of getting a household with both features.
The answer would be 1/2 or 50% if we didn't have the prior knowledge of the household having an answering machine. But with this prior knowledge, the conditions change and so does the probability.
----------------
You could also compute 0.50/0.90 to get the same answer.
A restaurant serves only tacos and enchiladas. If 60% of everyone who ate at the restaurant on a certain day ordered tacos, what percentage of those who ate at the restaurant ordered enchiladas that day
Answers
Answer:
i. 70%
ii. 70%
Step-by-step explanation:
Since in the question, it is given that 60% of everyone is ordered tacos so 40% of everyone is ordered enchiladas
i. Now if half ordered tacos that means out of these 30 orders enchiladas.
since 30 ordered tacos that means 70% ordered enchiladas
ii. Now for 3 by 4 we have to assume the number of people who ordered only enchiladas be x
So,
For both, it would be 0.75 x
And, the number of people who did not order is 40 as 60 tacos are ordered by people
So, the percentage is
= 40 × 0.75 + 40
= 30 + 40
= 70%
Plane A is descending toward the local airport, and plane B is ascending from the same airport. Plane A is descending at a rate of 2,500 feet per minute. Plane B is ascending at a rate of 4,000 feet per minute. If plane A is currently at an altitude of 14,000 feet and plane B is at an altitude of 1,000 feet, how long will it take them to be at the same altitude? The equation representing plane A’s descent is y = -2,500x + 14,000. The equation representing plane B’s ascent is y = 4,000x + 1,000. In both equations, y represents altitude and x represents time in minutes.
Answers
Answer: 2 minutes
Step-by-step explanation:
Given the following :
Plane A's descent :
y = -2,500x + 14,000
Plane B's Ascent :
y = 4,000x + 1,000
where y = altitude x = minute
Time to be at the same altitude :
Being at the same altitude means ;
Plane A's descent = Plane B's Ascent
-2,500x + 14,000 = 4,000x + 1,000
-2500x - 4000x = 1000 - 14000
-6500x = - 13000
x = 13000 / 6500
x = 2
x = 2minutes.

Two 6-sided dice are rolled. What is the probability the sum of the two numbers on the die will be 3?
Answers
Answer as a fraction = 1/18
Answer in decimal form (approximate) = 0.0556
Answer in percent form (approximate) = 5.56%
========================================================
Explanation:
We have 6*6 = 36 ways to roll out two dice. I recommend making a chart to show all the possible outcomes. You can search online for a "dice chart" or "sum of dice chart" and one will be made for you. The chart is a handy reference to see all the outcomes.
Of those 36 total outcomes, only 2 outcomes have the dice add to 3. Those two outcomes are 1+2 and 2+1.
So the number of events we want is 2 out of 36 total, meaning 2/36 = 1/18 is the probability.
Using your calculator, you should find that 1/18 = 0.0556 approximately, which converts over to 5.56% roughly.
The probability the sum of the two numbers on the die will be 3 is 5.56% roughly.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
