A pipe leaks water at a rate of 48 fl oz
every 5 min.
At this rate, how many gallons of water leak from the pipe in an hour? (1
gal = 128 fl oz)
The number of gallons of water leaking from the pipe in an hour will be 4.5 gallons per hour.
What is conversion?Unit modification is the process of converting the measurement of a given amount between various units, often by multiplicative constants that alter the value of the calculated quantity without altering its impacts.
A pipe leaks water at a rate of 48 fl oz every 5 min. Then the rate is given as,
Rate = 48 / 5 fl oz per minute
We know that 1 gal = 128 fl oz, then we have
Rate = (48 / 128) / (5 / 60)
Rate = (48 x 60) / (128 x 5)
Rate = 2880 / 640
Rate = 4.5 gallons per hour
The number of gallons of water leaking from the pipe in an hour will be 4.5 gallons per hour.

ENG 12:13 AM
INTL 2/3/2021
Answer:
23 degrees
Step-by-step explanation:
Find the diagram attached
The sum of angle on the straight line is 180°
103+3x+15+x+10 = 180
128+4x =180
4x = 180-128
4x = 52
x = 52/4
x = 13
The measure of the angle of the intersection between Derby Drive and Rosemont is x+10
= 13+10
= 23 degrees
Hence the measure of the angle is 23 degrees
The amount of money in a bank account increased by 17.5 % 17.5% over one year. If the amount of money at the beginning of the year is represented by A A, which expression below represents the amount of money in the bank account after the increase?
Answer: 1.175A
Step-by-step explanation:
From the information given in the question, we are told that the amount of money that is in a bank account increased by 17.5% while the money at the beginning of the year is represented by A.
The expression that represents the amount of money in the bank account after the increase will be:
= A + (17.5% × A)
= A + (17.5/100 × A)
= A + (0.175 × A)
= A + 0.175A
= 1.175A

Rewrite the system of equations in slope intercept form
Y - 5 = -4x
3y - 9 = -6x
The slope-intercept form of the first equation is _______
The slope intercept form of the second equation is _______
Answer:
✔ y = –4x + 5
✔ y = –2x + 3
Step-by-step explanation:
We can write -
The slope-intercept form of the first equation is y = - 4x + 5.The slope intercept form of the second equation is y = - 2x + 3.What is the general equation of a Straight line?
The general equation of a straight line in slope intercept form -
y = mx + c
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
Other possible equations of lines are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}We have the given system of equations as -
y - 5 = - 4x
3y - 9 = - 6x
The given system of equations is -
y - 5 = - 4x
3y - 9 = - 6x
Now -
y - 5 = - 4x
y = - 4x + 5
and
3y - 9 = - 6x
3y = - 6x + 9
y = (-6/3)x + (9/3)
y = - 2x + 3
So, we can write -
The slope-intercept form of the first equation is y = - 4x + 5.
The slope intercept form of the second equation is y = - 2x + 3.
Therefore, we can write -
The slope-intercept form of the first equation is y = - 4x + 5.The slope intercept form of the second equation is y = - 2x + 3.To solve more questions on straight lines, visit the link below-

Answer:
C
Step-by-step explanation:
The 3 triangles are all similar.
Using the 2 inside then the ratios of corresponding sides are equal, that is
[tex]\frac{x}{3}[/tex] = [tex]\frac{12}{x}[/tex] ( cross- multiply )
x² = 36 ( take the square root of both sides )
x = [tex]\sqrt{36}[/tex] = 6 → C
Answer:
C) x = 6
because this is a right triangle
=> we have:
(12² + x²)(3² + x²) = (15x)²
<=> 1296 + 153x² + x⁴ = 225x²
<=> x⁴ - 72x² + 1296 = 0
<=> (x² - 36)² = 0
<=> x² = 36
=> x = 6

3)b
4)D
Step-by-step explanation:
Your welcomeee
Answer:
1. a
2. c
3. a
4. b
Step-by-step explanation:
1. Factor 15x + 35 using the GCF
The GCF (Greatest common factor) between these two numbers is 5. In other words, both 15x and 35 can be divided by 5. So if you divide both by 5 and then multiply it by 5, you will get 5(3x + 7), or "a".
2. Which expression is equivalent to -5(x + 10)?
Multiply the x and 10 by -5. You will get -5x - 50, or "c"
3. Subtract (8x + 6) - (x + 4)
Multiply the second parentheses by -1 (because there is a subtraction sign in front of it. This is the same as + (-1)), and then open the parentheses.
8x + 6 - x - 4
7x + 2, or "a"
4. Add (11x + 2) + (9x - 4)
Open the parentheses
11x + 2 + 9x -4
20x -2, or "b"
