A leaking pond loses 12 gallon of water in 23 hours How many gallons of water will it lose in 31 hours
Answers
Answer:
The volume of water the pond will lose in 31 hours is 17.71 gallons.
Step-by-step explanation:
Given;
Rate of water leakage, R = 12 gallon of water in 23 hours
[tex]R = \frac{12 \ gallons}{23 \ hours}[/tex]
In 31 hours the volume of water leaked is calculated as;
[tex]V = \frac{12 \ gallons}{21 \ hours} \times 31 \ hours\\\\V = 17.71 \ gallons[/tex]
Therefore, the volume of water the pond will lose in 31 hours is 17.71 gallons.

Answers
10x + 20y = 690
Now get x by itself on one side by subtracting y
10x = 690 - 20y
Divide by 10 on both sides
X = 69 - 2y
Now plug this value for x into a separate equation just showing the amount of coins
(X+y=45)
69 - 2y + y = 45
Now solve for y
69 - y = 45
-y = -24
Y = 24
Now plug this y value into the same equation to solve for x
X + 24 = 45
X = 21
To check this work add both values into the original equation and solve
10(21) + 20(24) = 690
210 + 480 = 690
690 = 690
Answer:
$10 coins: 21
$20 coins: 24
Step-by-step explanation:
So we can create 2 equations where
x = number of $10 coins
y = number of $20 coins:
x + y = 45
10x + 20y = 690
we can move equation 1 around so that we can get a value of x
x = 45 - y
now we can substitute x into the second equation
10(45 - y) + 20y = 690
450 - 10y + 20y = 690
10y = 240
y = 24
Now plug in y back into the first equation
x = 45 - y
x = 45 - 24
x = 21
What is ____ of the x-intercept is
The
always zero.
A . X-coordinate
B. Y-coordinate
Answers
I just looked it up.
The x-intercept is Y-coordinate always zero which is the correct answer that would be an option (B).
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
What is x-Intercept?The x-intercept is defined as an intercept that is located at the x-axis of the plane, is the location or coordinate from where the line crosses
The general form of the linear equation, where m and b are constants, is written as y = mx + b. . As a result, the value of the y-coordinate in the corresponding linear equation will always be zero when it crosses the x-axis.
The y-coordinate for the x-intercept and the x-coordinate for the y-intercept are both zero. Another name for the x-intercept is the horizontal intercept.
Therefore, the x-intercept is Y-coordinate always zero which is the correct answer that would be an option (B).

For the second quarter of 2015, Apple sold 61.0 million iPhones. This represented a year- over-year increase of 40%. What were the sales for iPhone for the same quarter in the previous year (rounded to the nearest 10,000)?
Answers
Answer:
It sold 43.57 iPhones for the same quarter in the previous year.
Step-by-step explanation:
It sold 61.0 million iPhone, which is an increase of 40% over the value of the previous year x.
This can be interpreted as:
61 million is 140% = 1.4 of the previous year amount, that is, x. So
[tex]1.4x = 61[/tex]
[tex]x = \frac{61}{1.4}[/tex]
[tex]x = 43.57[/tex]
It sold 43.57 iPhones for the same quarter in the previous year.

Find the value of x in the triangle shown
Answers
Answer:
5
Step-by-step explanation:
you need to use the Pythagorean theorem
a^2+b^2=c^2
a&b=sides
c=hypotonuse
plug the side values into the equation
4^2+3^2=c^2
16+9=c^2
25=c^2
you have to square root 25 to find c itself
c=5
Answer : would be 5
Because a triangle that has a sequence of the number 3 & 4, or 3 & 5, or 4 & 5 will always consider of the number 3,4 and 5.
Also if te triangle did consist of different numbers the Pythagorean theorem ( a^2 + b^2 = c^2 ) can be use.
So in this case it’ll be 3^2 + 4^2 = c^2
9 + 16 = c^2
25 = c^ 2
Then we square root both sides and the answe will be : 5 = c

ANSWER ALL OF THIS FFOR ME PLS WITH EXAMPLES
Answers
1. 3 shorts
$11 * 5 shirts = $55
$82-$55= $27
$27 left you divide by 9 because that’s how much each shorts were and you get 3 shorts
2. so for the special she buys 6 right
which means you could just add another $15
because half of 6 is 3 and with those 3 you pay $15 for the special and so just add another which means you’d pay $30 bucks for 6 of them. and normally without the deal she’d pay $54 because you times $9 with 6 lotions. and so now you subtract $54-$30= $24. meaning you saved $24.
3. so if she spent $18 just group them. first you start of with $3 and get 10 cards now you do 6 more groups because 3 times 6 = 18 and now when you group them you have 6 groups with 10 cards and times those 2 you get 60 cards.
4. $17 each month
$2 times 8 = 16 bucks add the 17 she has to pay each month and you get $33.
5. 4 plots with 5 fruits trees in each meaning you have 20 trees in total.
so now add to each tree 3 fruits and take away 17 of them and in 1 plot you have 15 fruits and from the second plot you take away 2 more fruits so at last you only have like 13 fruits of the second plot and 2 more plots that are complete and in each plot there are 15 fruits
now add 15 fruits (for one plot) and another 15 (for the other) which equals 30 fruits
and you still have 13 and add 30 you get 43 fruits left.

Which one is a cheaper buy, a 24-cm by 24-cmn pizza for
7350.00 or a 30-cin diameter circular pizza for the same price.
Explain.
Answers
Answer:
The circular pizza is cheaper because you pay less money for a unit area of the pizza
Step-by-step explanation:
Step one:
given data
The dimension of the square pizza is
24 X 24 cm
The area is
= 576cm^2
Also, the dimension of the circular pizza is
DIameter = 30cm
radius = 30/2 = 15cm
The area is
= πr^2
=3.142*15^2
=706.95cm^2
Step two:
let us find the cost per area of each of the shape of the pizzas
For the square pizza the cost per area is
= 7350/576
=$12.76 per area
For the circular pizza, the cost per area is
= 7350/706.95
=$10.40 per area
The top speeds for a sample of five new automobiles are listed below. Calculate the standard deviation of the speeds. Round to four decimal places. 170, 160, 130, 165, 125
Answers
Answer:
20.92
Step-by-step explanation:
Given the data:
X : 170, 160, 130, 165, 125
Standard deviation (s) :
s = √Σ((X - m)² / n)
m = mean
n = sample size
Mean , m = Σx/n
m = (170 + 160 + 130 + 165 + 125) / 5
m = 750/5
m = 150
((X - m)² / n - 1)
[(170-150)^2 + (160-150)^2 + (130-150)^2 + (165-150)^2 + (125-150)^2] / (5-1)
= 1750 / 4
= 437.5
s = √437.5
s = 20.9165
s = 20.92
