A standard showerhead dispenses 21 gallons of water in 30 mins. At this rate, how many gallons of water will a standard showerhead dispenses in 13 minutes.
Answer:
9.1 gallons of water.
Step-by-step explanation:
A standard showerhead dispenses 21 gallons of water in 30 mins. At this rate, how many gallons of water will a standard showerhead dispenses in 13 minutes?
30 minutes = 21 gallons
13 minutes = x gallons
Cross Multiply
30 minutes × x = 13 minutes × 21 gallons
x = 13 minutes × 21 gallons/30 minutes
x = 9.1 gallons of water
Therefore, a standard showerhead dispenses 9.1 gallons of water in 13 minutes.

Answer:
$2000
Step-by-step explanation:
The value of the savings account is
v(m) = 2000(1.005)^m
where m is the number of months.
Compare with the formula for compound interest,
F = P(1 + r)^(nt)
where P = principal amount invested.
Answer: $2000
Evaluate each expression for the given value of the variable : x+1/2 + 5x-3/10 when x=3
Answer:
18 1/5
Step-by-step explanation:
1. First, we can convert all the x's into 3's
Our Equation: 3+1/2 + 15 - 3/10
2. Now we know that 3+1/2 = 3 1/2
Our Equation : 3 1/2 + 15 - 3/10
3. Now, we can add 3 1/2 + 15
Our Equation: 18 1/2 - 3/10
4. Next we can convert 1/2 so that the denominator is 10 and we get 18 5/10
Our Equation: 18 5/10 - 3/10
5. Now, we can subtract 3/10 from 5/10
Our Answer: 18 2/10 or 18 1/5
Hope this Helps!!! :)

Answer:
B
Step-by-step explanation:
The cylindrical part
Area of the cylindrical part = Circumference of the circle * height
Area of the cylindrical part = pi * d * height
Area = 3.14 * 10 * 9
Area = 282.6
Lid
Area = pi * r^2
r = 5
Area = 3.14* 5^2 * 2
Area = 157
Total 439.6
I know this doesn't look right according to the diagram, but it is the only way that you can solve the question. That is, you must assume there are two lids, not one as the diagram suggests.

f (-5) = ??
Answer:
7
Step-by-step explanation:
The function is f(x) so if x is replaced with a number, that's the value that x is in the equation. In this case, it'll be -5, so go to -5 on your graph. The y value is 7.
What point is a solution for the linear inequality below?
A. (4, 3)
B.(-2, 4)
C.(-4,1)
D.(1, -2)
Answer:
B.
Step-by-step explanation:
Any point in the highlighted (red) region will be in our solution set.
Note that our line is dotted. Thus, any points on the line is not in our solution set.
So, we can simply go through each point and check.
A is on the line. So, A is not a solution.
B is within the red region. Hence, B is our solution.
C is on the line. So, C is not a solution.
And D is not in the red region. So, D is not a solution.
Therefore, our answer is B.

2)
Slope =
Slope =
Answer:
1. Slope = -2
2. Slope = ⁴/3
3. Slope = -3
4. Slope = 1
Step-by-step explanation:
1. Using two points on the line, (0, 0) and (-1, 2):
[tex] slope = \frac{y_2 - y_1}{x_2 - x1} = \frac{2 - 0}{-1 - 0} = \frac{2}{-1} = -2 [/tex]
2. Using two points on the line, (0, 0) and (3, 4):
[tex] slope = \frac{y_2 - y_1}{x_2 - x1} = \frac{4 - 0}{3 - 0} = \frac{4}{3} [/tex]
3. Using two points on the line, (0, 0) and (-1, 3):
[tex] slope = \frac{y_2 - y_1}{x_2 - x1} = \frac{3 - 0}{-1 - 0} = \frac{3}{-1} = -3 [/tex]
4. Using two points on the line, (0, 0) and (2, 2):
[tex] slope = \frac{y_2 - y_1}{x_2 - x1} = \frac{2 - 0}{2 - 0} = \frac{2}{2} = 1 [/tex]

Solve for x and y.
y = 2/3x - 2
y = -x + 3
Answer:
1. x= 3y+6/2
y=2/3x-2
2.x=−y+3
y=−x+3
Step-by-step explanation:
1. Let's solve for x.
y=2/3x-2
Step 1: Flip the equation.
2/3x-2=y
Step 2: Add 2 to both sides.
2/3x-2+2=y+2
2/3x=y+2
Step 3: Divide both sides by 2/3.
2/3x/2/3=y+2/2/3
x= 3y+6/2
Let's solve for y.
y=2/3x-2
2. Let's solve for x.
y=−x+3
Step 1: Flip the equation.
−x+3=y
Step 2: Add -3 to both sides.
−x+3+−3=y+−3
−x=y−3
Step 3: Divide both sides by -1.
-x/-1=y-3/-1
x=−y+3
Let's solve for y.
y=−x+3
here are two graphs if you need a better explanation

Write the equation of the line that goes through (-2/3, 7/8) and is PARALLEL to 3x + 4y = 7
Answer:
6x+8y = 3
Step-by-step explanation:
we have 3x + 4y = 7
4y = -3x + 7
y = -3/4 x + 7/4
so slope is -3/4
2 parallel lines always have same slope
so the slope of our new line is -3/4
so y = -3/4 x + C
for c,
we have (x,y) = (-2/3,7/8)
7/8 = -3/4 * -2/3 + C
C = 3/8
so equation is
y = -3/4 x + 3/8
simplyfyig,
8y = -6x + 3
or, 6x+8y = 3
If leticia invested $12,000 in an account in which the interest earned is continuously compounded at a rate of %2.5 find the total amount after 15 years
Given:
Principal value = $12000
Rate of interest = 2.5%
To find:
Total amount after 15 years.
Solution:
Formula for amount discontinuously compounded interest is
[tex]A=Pe^{rt}[/tex]
where, P is principal, r is rate of interest and t is time in years.
Substitute P=12000, r=0.025 and t=15 in the above formula.
[tex]A=12000e^{0.025(15)}[/tex]
[tex]A=12000e^{0.375}[/tex]
[tex]A=12000(1.45499141462)[/tex]
[tex]A=17459.8969754[/tex]
[tex]A\approx 17459.897[/tex]
Therefore, the amount after 15 years is $17459.897.
help me pls i want to pass my math class
Answer:
D
Step-by-step explanation:
You know the slope has to be -5, because in the equation it says -5x. You know the y intercept has to be a number on the y axis, and since it says the y intercept is 4 in the equation, you would know its (0,4).
Half the value of 3x-9 is x+37. What is the value of x?
Step-by-step explanation:
3x-9=2x+73
3x-2x=73+9
x=82
Answer:
x = 83
Step-by-step explanation:
3x-9 / 2 = x + 37
1. multiply both sides by 2 to get rid of the fraction
3x - 9 = 2x + 74
2. move the variable to one side and the numbers to another side
3x - 2x = 74 + 9
x = 83
If f(x) is an even function and (6, 8) is one the points on the graph of f(x), which reason explains why (–6, 8) must also be a point on the graph? Since the function is even, the outputs of a negative x-value and a positive x-value are the same. Since the function is even, the outputs of a negative y-value and a positive y-value are the same. The graph has rotational symmetry, so the point will be reflected across the y-axis. The graph has rotational symmetry, so the point will be rotated 90 degrees about the origin.
The correct option is,
⇒ Since the function is even, the outputs of a negative x-value and a positive x-value are the same.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Since, We know that;
A function is "even" when f(x) = f(−x) for all x.
Now, Geometrically speaking, the graph face of an even function is symmetric with respect to the y-axis, meaning that its graph remains unchanged after reflection about the y-axis.
So, If point (6, 8) is one the points on the graph of f(x),
Then, f (6) = 8
And, since function is even, you can state that;
⇒ f(-6) = f(6) = 8.
This means that point (-6,8) must also be a point on the graph. Geometrically it means that the output of a negative x-value and its opposite is the same.
Thus, The correct option is,
⇒ Since the function is even, the outputs of a negative x-value and a positive x-value are the same.
