Answer:

$48.75

Step-by-step explanation:

To find 25% of 650 you find 50%. To do this you divide 650 by 2 which is 325. you then divide that by 2 again to get $162.50. That is the sale price.

You now need to find 30% of 162.50. To do that you find 10% 3 times because 10x3 is 30. To find 10% you divide 162.50 by 10 to get 16.25.

16.25x3 is $48.75 which is our answer.

The comparison of shoes placed on the floor by Helena next to each other change from reflection to translation.

The reflection of a plane or shape is flipping the original figure with respect to a reference line.

The rule of reflection are given below,

Before training for the obstacle course, Helena bought a new pair of athletic shoes.  

Now she had accidentally purchased two left shoes. Now, if she puts a left shoe to another left shoe, then it looks like the translated image of the first shoe.

Hence, the comparison of shoes placed on the floor by Helena next to each other change from reflection to translation.

Answer

f(x) = -9 cos((12(pi) / 7)x) -11

The base equation for a cosine graph is

f(x) = a cos(b(x-c))+d

a = amplitude

b = period

c = phase shift

d = vertical shift

if there's a reflection over the x-axis then there is a negative sign in front of the amplitude

The farthest from a normal distribution is,

e) 2, 4, 5, 5, 6, 6, 7, 7, 7, 8, 8, 9, 9, 10

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given are 4 data sets.

And, We have to check which is farthest from normal distribution.

We know that a normal distribution is bell shaped with mean = median = mode.  

Also 99% lie within 3 std deviations from the mean.

Here, This data set has a bimodal distribution with two distinct peaks, which is not characteristic of a normal distribution.

And, The other data sets have a unimodal distribution with a more symmetrical shape, which is closer to a normal distribution.

Answer:

  ∠B = 40°

Step-by-step explanation:

The given angle relations can be expressed in two equations.

__

  A + B = 90° . . . . . . . . angles are complementary

  A×(1 -20%) = B . . . . . B is 20% smaller

__

Using the second equation to substitute for B in the first equation, we get ...

  A + 0.80A = 90° . . . . . . substitute for B

  A = 90°/1.8 = 50° . . . . . collect terms, divide by the coefficient of A

  B = A(0.80) = 40° . . . . find B from A

The measure of angle B is 40°.

Answer:

2412.7 ft^3

Step-by-step explanation:

If a circle has a diameter 16ft, it's radius is half that, or 8ft. The are of the circle/base of the cylinder is given by the formula [tex]\pi r^2[/tex] where r is the radius. This means the area is 64π ft^2.

To find the volume of a cylinder, you multiply the base area and the height, so the volume would be 64π x 12 which is 2412.74315796. When rounded to the nearest tenth, this is 2412.7.

Since we want to find the volume of a cylinder:

 ⇒ must know the formula: [tex]V = \pi r^2h[/tex]

Consider the information given:

Let's solve:

  [tex]V = \pi r^2*h=3.14*(8)^2*12=2411.52_.cm^3[/tex]

Answer:

D.  They do not have the same ratio of girls to boys because a straight line cannot be drawn through the points (14, 16), (17, 19), and (0, 0) on a coordinate grid.

Step-by-step explanation:

In order to check if the ratio is the same, convert the ratios to (x, y) points, plot them on a graph and see if you can draw a straight line through them and the origin (0, 0).  If you can, then the ratios are the same.  If not, then the ratios are not the same.

After plotting (14, 16) and (17, 19) and (0, 0) on a graph (attached), you can see that a straight line will only go through any two of the points, but not all three.  Therefore, the ratios are not the same.

In congruent figures ABCD and WXYZ, corresponding angles are angles that have the same position relative to their respective vertices.

In congruent figures ABCD and WXYZ, corresponding angles are angles that have the same position relative to their respective vertices.

For example, angle A and angle W are corresponding angles, as they are both opposite the vertex where angle D and angle X are vertices.

Similarly, angle B and angle X, angle C and angle Y, and angle D and angle W are all corresponding angles in the congruent figures ABCD and WXYZ.
