Answer:
105
Step-by-step explanation:
First, you are going to convert dollars to cents. Since there are 100 cents in a dollar, multiple $20 by 100. Now you should have 2,000 cents. Now all you have to do is divide by 19, the cost of the stamps, and you should get 105.26. Because you can't by part of a stamp your answer would be 105.

Step-by-step explanation:
(3x2)(−2x4) = 3(−2)x2∙4 = 6x8
Could you please find out what's wrong and say what should be there instead? The problem is : (3x to the power of 2 ) (-2x to the power of 4) = 3(-2)x to the power of 2.4 = 6x to the power of 8
Answer:
The correct answer is -6x⁶
Step-by-step explanation:
Given that:
[tex]3x^2 ( - 2x^4 ) \\ \\ =3(-2)x^{2.4} \\ \\ = 6x^8[/tex]
From the second step above, using the law of indices the correct format should be
[tex]= (3\times -2)x^{2+4}[/tex]
So, the problem lies where we have 2.4, it is not supposed to be (2*4). It supposed to be 2+4 because the law of indices states that we multiply the index together and add their power.
Then the result of that yields
= -6x⁶
In the third step, they also omit the negative sign, when multiplying (3 * -2).
Thus, the correct answer is -6x⁶

When a figure is rotated, does every point move the same distance? Explain.
Choose the correct answer below.
O A. Yes. When rotating a figure, the rotation indicates that each point moves the same distance, such that the angle of rotation may vary from point to point
OB. No. The angle of rotation is different for each point, and each point and its image are, therefore, different distances from the center of rotation, so the
distance each point moves varies.
O C. Yes. Since the angle of rotation is the same, the distance that each point moves is the same.
OD. No. Although each point is rotated through the same angle, points that are different distances from the center of rotation move different distances.
Ku
Answer:
D. No. Although each point is rotated through the same angle, points that are different distances from the center of rotation move different distances.
Step-by-step explanation:
Rotation is a type of transformation which involves turning a given figure about a reference point to produce its image. This would produce an image with the same size as the object.
A given figure or shape has different parts or points. Since each point on the figure is at different distance to the reference point, thus they do not cover the same distance but move through the same angle of rotation. Each individual point move through the same angle but do not cover the same distance during rotation.
Therefore, the appropriate option is D.

A morning truck can carry no more than 1480 pounds of cargo. Brian loaded 640 pounds into the truck already. He is loading boxes that weigh 70 pounds. How many boxes can he out into the truck
Given :
A morning truck can carry no more than 1480 pounds of cargo.
Brian loaded 640 pounds into the truck already.
He is loading boxes that weigh 70 pounds.
To Find :
How many boxes can he out into the truck.
Solution :
Weight left for carrying cargo, W = 4180 - 640 pounds
W = 3540 pounds
Number of boxes of 70 pounds cargo he can carry in truck is :
[tex]n =\dfrac{3540}{70}\\\\n = 50.57[/tex] ≈ 50 .
Therefore, number of box they can carry is 50.
Hence, this is the required solution.

If A:B = 5:18 and B:C = 6:4, form the ratio A:B:C
Answer:
5 : 18 : 12
Step-by-step explanation:
Express the ratio B : C in fractional form, that is
[tex]\frac{B}{C}[/tex] = [tex]\frac{6}{4}[/tex] ( cross- multiply )
6C = 4B ( divide both sides by 6 )
C = [tex]\frac{4}{6}[/tex] B = [tex]\frac{2}{3}[/tex] B , then
C = [tex]\frac{2}{3}[/tex] × 18 = 2 × 6 = 12
Hence
A : B : C = 5 : 18 : 12
Answer:
5:18:12
Step-by-step explanation:
5:18
_:6:4 --> since you multiply 6 by 3 to get 18, multiply 4 by three to get the A:B:C ratio.

Since graph is intersecting x-axis at 3 and 6, therefore 3 and 6 are zeros of this function.
The zeros of the function are x = 3 and x = 6
How to determine the zeros of the function?The zeros of the function are the x values where the graph crosses the x-axis
From the figure, the graph crosses the x-axis at:
x = 3 and x = 6

One of these scenarios represents a direct variation and one does not. How can you tell the difference? a) A large pizza with one topping costs $15.50. A large pizza with 4 toppings costs $20. Does the price vary directly with the number of toppings? b) A marathoner ran 5 miles in 40 minutes and 15 miles in 120 minutes. Does the number of minutes vary directly with the number of miles? Your answer:
Answer: See explanation
Step-by-step explanation:
a) A large pizza with one topping costs $15.50. A large pizza with 4 toppings costs $20.
A large pizza with one topping costs $15.50.
Using the formula for direct variation,
y = kx
where,
y = Cost of pizza
x = number of toppings
k = constant of proportionality
15.50 = 1k
k = 15.50
A large pizza with 4 toppings costs $20.
Using y = kx
20 = 4k
k = 20/4
k = 5
Here, the price does not vary directly with the number of toppings because the constant of proportionality is different.
b) A marathoner ran 5 miles in 40 minutes and 15 miles in 120 minutes.
Using y = kx
where,
y = 40
x = 5
y = kx
40 = 5k
k = 40/5
k = 8
Using y = kx
where,
y = 120
x = 15
y = kx
120 = 15k
k = 120/15
k = 8
The number of minutes vary directly with the number of miles. This is because the constant of proportionality is thesame in both cases.
Therefore, the second one(B) represents a direct variation and the first one (A) doesn't.

Are the two lines equations parallel, perpendicular, or neither? 10x+8y=16 5y=4x-15
Answer: Neither
Step-by-step explanation: if you look at both slopes 10x and 4x they are neither the reciprocal or even remotely close to each other
The two equations 10x+8y=16 and 5y=4x-15 are perpendicular to each other.
What is an equation?The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.
The two given equations are 10x+8y=16 and 5y=4x-15 then reduce both the equations in the intercept form of the standard line of the equation.
The standard form of the equation of the line is,
y = mx + c
For the equation: 10x+8y=16
10x + 8y = 16
5x + 4y = 8
4y = -5x + 8
y = (-5/4)x + 2
For the equation: 5y=4x-15
5y = 4x -15
y = ( 4/5 )x - 3
The slope of line 1 is ( -5/4 ) and the slope for line 2 is ( 4/5 ). Here, the slope of the lines is opposite and reciprocal of each other. The lines will be perpendicular to each other.
Therefore, two equations 10x+8y=16 and 5y=4x-15 are perpendicular to each other.

A building 78 feet tall casts a shadow 64 feet long. Find the measure of the angle of elevation of
the sun?. Draw a right triangle and round to the nearest tenth of a degree.
Answer:
50.6°
Step-by-step explanation:
The reference angle = angle of elevation [tex] (\theta) [/tex]
Side opposite to the reference angle = 78 ft
Adjacent side = 64 ft
Applying trigonometric ratios formula, we would have:
[tex] tan(\theta) = \frac{opposite}{adjacent} [/tex]
Plug in the values
[tex] tan(\theta) = \frac{78}{64} [/tex]
[tex] tan(\theta) = 1.21875 [/tex]
[tex] \theta = tan^{-1}(1.21875) [/tex]

are the two lines parallel, perpendicular, or neither ?
Answer:
Perpendicular
Step-by-step explanation:
the lines are Perpendicular or it can also be parallel
The lines in Graph 1 is neither, graph 2 is parallel, graph 3 is parallel and graph 4 is perpendicular.
What are Parallel Lines?Parallel lines are those straight lines in a plane which will not intersect each other even if we extend the line to infinity.
Perpendicular lines are those lines where the two lines meet a point where the angle between the two lines is 90 degrees.
Graph 1 :
Lines are not parallel because if we extend one line it will meet the other line.
Lines are not perpendicular since the point of intersection will never make the angle between the lines as 90 degrees.
So it is neither parallel nor perpendicular.
Graph 2 :
The two lines will never intersect if we extend the line infinity.
So they are parallel.
Graph 3 :
Again the lines are parallel since they won't intersect at any point.
Graph 4 :
Since both the lines make a 90 degree angle at the point of intersection, they are perpendicular.
Hence the lines are parallel in graph 2 and 3, lines are perpendicular in graph 4 and lines are neither in graph 1.
