Answer: 34.98
Step-by-step explanation:
'Percent (%)' means 'out of one hundred':
6% = 6 'out of one hundred',
p% is read p 'percent',
6% = 6/100 = 6 ÷ 100
What does it mean to calculate the percentage of a number?
6% of 583 = ?
... is equivalent to multiplying them:
6% × 583 = ?
6% of 583 =
6% × 583 =
6/100 × 583 =
(6 ÷ 100) × 583 =
6 × 583 ÷ 100 =

what is the following solution to this absolute value equation?
6|-f + 3| + 7 >7
The solution of this absolute value equation is f<3
What is absolute value?Absolute value describes the distance from zero that a number is on the number line, without considering direction. The absolute value of a number is never negative.
On subtracting 7 from both sides
=6|-f + 3| + 7 - 7 > 7 - 7
=6|-f + 3| > 0
Now diving both sides by 6
|-f + 3| > 0
Now, this results in two condition
1.) -f+3>0
So,
f<3
2.) -(-f+3)<0
So,
3-f<0
f<3
Therefore, f can accept any value that satisfies the equation f<3.

Mr. Mole left his burrow and started digging his way down.
AAA represents Mr. Mole's altitude relative to the ground (in meters) after ttt minutes.
A=-2.3t-7A=−2.3t−7A, equals, minus, 2, point, 3, t, minus, 7
How fast did Mr. Mole descend?
Mr mole descend at the rate of 2.3 meters per minutes.
A rate in mathematics is the comparison of two related values expressed in dissimilar units.
The numerator of the ratio expresses the equivalent rate of change in the other (dependent) variable if the denominator of the ratio is presented as a single unit of one of these quantities and it is expected that this number may be altered systematically (i.e., is an independent variable).Examples of rates that are usually represented as "per unit of time" are speed, heart rate, and flux. An example of a ratio having a non-time denominator is the electric field ratio. Other examples include exchange rates and literacy rates (in volts per meter).The given equation to represent the position of Mr. Mole is
A = -2.3 t - 7
where A denotes the depth and t is the time.
Now the rate can be found out by dividing the change in depth by the change in time.
Differentiating we get
ΔA = -2.3 Δt
or, ΔA / Δt = -2.3
hence the rate of the mole is 2.3 meters per minutes.

In this question, we have been given a rectangular based pyramid PQRST.
A pyramid has height of 10 cm.
We need to find the angle between the line PT and the plane PQRS.
We know that the angle made by triangular plane TPS with the rectangular plane PQRS is same as the angle between the line PT and the plane PQRS.
If we draw a perpendicular through point T and intersects the plane PQRS at point M.
Let R be the midpoint of side PS
Consider a right triangle RMT.
We need to find angle TRM.
Here, MT = 10 cm, MR = 5 cm (1/2 × length of the rectangle)
Consider the tangent of the angle TRM
tan(∠TRM) = TM / RM
tan(∠TRM) = 10 / 5
∠TRM = tan^(-2)[2]
∠TRM = 63.4°

Answer:
y = (3/2)x + 3
Step-by-step explanation:
Comment
The general equation is
y = mx + b
Finding m
The equation for the slope is
m = (y2 - y1)/(x2 - x1)
Givens
y2 = 3
y1 = 0
x2 = 0
x1 = - 2
m = (3 - 0)/(0 - -2)
m = 3 / 2
m = 3/2
Finding b
b is the y intercept which is (0,3)
x = 0
y = 3
3 = 0*3 + b
b = 3
So the equation is
y = (3/2) x + 3
9. The amount of water used by a washing
machine varies directly with the weight of the
load being washed. The washing machine uses
28 gallons to wash 7 pounds of clothing. How
many gallons of water will the machine
use to wash 24.5 pounds of laundry?
The machine will use 90 gallons of water to wash 24.5 pounds of laundry.
What is Direct Variation?If two quantities change by the same amount, they are said to follow a direct variation. As a result, when one quantity changes, the other follows suit, increasing when the first increases and decreasing when the first decreases. To put it another way, two quantities are said to be directly proportional to one another if the ratio of the first to the second is a constant term. The coefficient or constant of proportionality is the name given to this constant quantity. Assuming that x and y are two quantities that are directly varying, they are stated as follows:y ∝ x
Consequently, y = kx, where k is the proportionality constant.
Given:
The amount of water used by a washing machine varies directly with the weight of the load being washed.
Let's assume,
The amount of water used by a washing machine is y.
The weight of the load being washed is x.
According to the question,
y = 28 gallons
x = 7 pounds
Putting the values we get,
y = kx
28 = k × 7
k = 4
Now, we have to find y when x = 24.5
y = 4 × 24.5 = 98
Hence the machine will use 90 gallons of water to wash 24.5 pounds of laundry.

the algebraic relationship between x and y?
(A)y=16/9x
(B)y=x+14
(C) x+y=50
(D)y=9/16x
The equation would be y = 16/9x which represents the algebraic relationship between x and y which is the correct answer would be an option (A).
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Given that x and y vary directly and y = 32 when x = 18
Direct variation equation can be written as:
y = kx where "k" is a constant.
Substitute the values of y = 32 and x = 18 in the direct variation equation and solve for k:
⇒ 32 = k(18)
⇒ k = 32/18
⇒ k = 16/9
The direct variation equation :
⇒ y = 16/9x
Therefore, the equation would be y = 16/9x which represents the algebraic relationship between x and y.

Using the unit rate, the graphs that best represent the amount they earn for different amount of time is: C.
How to Interpret the Slope?The slope of a graph can be interpreted as the unit rate of the scenario that is being represented by the graph. For example, money earned in dollars per hour worked is the unit rate or slope of the graph given in this scenario.
The larger the unit rate value, the steeper the slope of the line of the graph.
Let Lin's unit rate be represented as x, therefore,
Lin's unit rate = x
Diego's unit rate = 2x
Jada's unit rate = 2(2x) = 4x

To solve this, we must first find the LEAST COMMON MULTIPLE (LCM).
To find the LCM, we must list the multiples of the denominators, then find the smallest multiple that all three numbers have in common.
2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50
5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50
25: 25, 50
The LCM is 50.
Now that we have found the LCM, we will change the fractions so that all three have a denominator of 50.
To do this, we multiply the numerator and the denominator by the same number.
[tex]\frac{1}{2} *\frac{25}{25} =\frac{25}{50}[/tex]
[tex]\frac{2}{5} *\frac{10}{10} =\frac{20}{50} \\[/tex]
[tex]\frac{2}{25} *\frac{2}{2} =\frac{4}{50}[/tex]
Now that all fractions have the same denominator, we can add them. Remember, when adding fractions, the denominators stay the same. Only add the numerators.
[tex]\frac{25}{50} +\frac{20}{50} +\frac{4}{50} \\\\=\frac{49}{50}[/tex]
_______________________________________________________
[tex]b.[/tex] [tex]\frac{2}{3} *\frac{30}{7} *\frac{14}{5}[/tex]
To multiply fractions, multiply the numerators, then the denominators. Lastly, simplify the product.

Here, y is the two equal sides of the right-angle triangle
So y + x + y = 11
Using Pythagoras's theorem for the right angle triangle
y² + y² = x²
2y² = x²
y² = (x²)/2
y = x /√2
So substitute the value of y = x /√2 in the equation
x /√2 + x + x /√2 = 11
2x /√2 + x = 11
2x /√2 + x√2 /√2 = 11
x[2/√2 + √2 /√2] = 11
x[(2 + √2) /√2] = 11
x(2 + √2) = 11√2
x = 11√2/(2 + √2)
x = 15.5563/3.4142 = 12.1421

A theater group made appearances in two cities. the hotel charge before tax in the second city was $500 higher than in the first. the tax in the first city was 6.5% and the tax in the second city was 6% the total hotel tax paid for the two cities was $748.7. how much was the hotel charge in each city before tax?
Using algebraic expression and equation, the hotel charge before tax in each city is $5749.60 and $6249.60, respectively.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
Let x = hotel charge before tax in the first city
If the hotel charge before tax in the second city was $500 higher than in the first, then
hotel charge before tax in the second city = $500 + x
If the tax in the first city was 6.5% and the tax in the second city was 6% and the total hotel tax paid for the two cities was $748.7, then
x(0.065) + ($500 + x)(0.06) = $748.7
Solving for x,
x(0.065) + ($500 + x)(0.06) = $748.7
0.065x + $30 + 0.06x = $748.7
0.065x + 0.06x = $748.7 - $30
0.125x = $718.7
x = $5749.60
hotel charge before tax in the first city = $5749.60
hotel charge before tax in the second city = $500 + x
hotel charge before tax in the second city = $500 + $5749.60
hotel charge before tax in the second city = $6249.60
