how many times smaller is the surface area of a cube if the side length is multiplied 1/2
​

9514 1404 393

Answer:

Step-by-step explanation:

Adding 10 and dividing by 4, we have ...

  4x < 28

  x < 7

The comparison does not include the "equal to" case, so the circle at x=7 is open. Values of x less than 7 are in the solution set. Those values are found to the left of 7 on the number line.

Answer:

C. The graph has an open circle at 7.

and

E.The arrow points left.

Answer:

206°

I realise that I didn't do it the easiest way. :(

Step-by-step explanation:

So first find angle XCY.

XCY = 180 - 72 - 26 = 82°

Then you can see that angle WCR is 154° because of vertical angles.

Arc RW is 154° too because WCR is a central angle.

Arc ZW is 26° because WCX is a central angle.

All we have to find now is angle ZCR.

You can see that ZCR and XCW are vertical angles.

ZCR = 26°

Arc ZR is also 26° because ZCR is a central angle.

154° + 26° + 26° = 206°

Answer:

1,736 square units

Step-by-step explanation:

To find the surface area, you must first find the area of all the faces, then add them all together. For this figure, you must find the area of two triangles, and three different rectangles.

Starting with the triangles, you can find the area using the equation: a=1/2bh. This gets 84 as the area of one triangle. Because you have two, you can multiply this area by two in order to get the area of both triangles. That value is 168.

Now, find the area of the bottom rectangle. Its dimensions are 24x28, and you can find the area of any rectangle by multiplying its base by its height. This area is 672.

The back rectangle's dimensions are 28x7, which equals 196.

The top rectangle is most difficult, as you must use the pythagorean theorem to find one of its side lengths: a^2 + b^2 = c^2. Its dimensions are 25x28, which equals 700.

Now add all those areas together to get the total surface area, or 1,736.

Answer: A - one solution, B - Infinite solutions, C - no solutions

Step-by-step explanation:

Solutions of linear equations are any points at which both lines intersect. The point of intersection provides a point that lies on both lines and satisfies both equations - hence why it is called a "solution" to the system of equations.

In the first diagram, the lines intersect once. There is only one solution to this system of equations at (2, 4).

In the second diagram, the lines are identical. They intersect for any possible value, meaning it has infinite solutions.

In the third diagram, the lines are parallel. They will stretch to infinity without ever intersecting each other, so this system has no solution.

Answer:

B 7.1 yd

Step-by-step explanation:

The approximate area of the circular garden is 7.1 square yards. Therefore, option B is the correct answer.

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.

Given that, the base of the rectangular grassy area is 6 yards by 3 yards.

A circular garden is surrounded by a rectangular grassy area.

Here, diameter of a circular garden is 3 yards and the radius is 1.5 yards.

We know that, area of a circle is πr²

The area of circular garden is 3.14×1.5²

= 3.14×2.25

= 7.065

≈ 7.1 square yards

Therefore, option B is the correct answer.

Question:

Tia performed an experiment where she flipped a coin 200 times. The coin landed heads up 92 times and tails up 108 times. Which statement about this experiment is true?

A) The ratio 92/200 represents the experimental probability of the coin landing heads up in this experiment.

B) The ratio 92/200 represents the number of trials in this experiment.

C) The ratio 92/100 represents the theoretical probability of the coin landing heads up in this experiment.

D) The ratio 92/100 represents the number of occurrences of the coin landing heads up in this experiment.

Answer:

A) The ratio 92/200 represents the experimental probability of the coin landing heads up in this experiment.

Step-by-step explanation:

Given that the number of times, n, Tia flipped a coin is 200 times, heads and tails landed 92 and 108 times respectively.

ie, n = 200

E(Head) = 92

E(Tail) = 108

Let's calculate the following probabilities:

Probability the coin landed heads =

P(H) = [tex] \frac{num of heads}{total num} = \frac{92}{200} = 0.46 [/tex]

Probability the coin landed tails =

P(H) = [tex] \frac{num of tailss}{total num} = \frac{108}{200} = 0.54 [/tex]

Here, the experimental probability of an event can be derived using:

Number of favourable events / total number.

The expermental probability of the coin landing heads up would be:

Number of heads / total number

[tex] = \frac{92}{200} [/tex]

Therefore the correct option is option A.

The ratio 92/200 represents the experimental probability of the coin landing heads up in this experiment.

In this question, we are to select which of the options represents the the amount earned working per hour last weekend by Samuel.

To get this, all we need to do is to divide the amount of money earned by the total

number of hours worked.

mathematically that is 18.9/2.25

Kindly note that 2 1/4 is same as 2.25

Dividing the above, we have 8.4

Hence , Samuel earned 8.40 per hour working last weekend

Scale factor of  cube to the smaller cube is 5 : 3.

Step-by-step explanation:

Ratio of the volumes of two cubes = [tex]\frac{\text{volume of large prism}}{\text{Volume of small prism}}[/tex]

                                                          = [tex]\frac{1000}{216}[/tex]

                                                          = [tex]\frac{125}{27}[/tex]

Scale factor of these cubes = [tex]\sqrt[3]{\text{ratio of the volumes of the cubes}}[/tex]

                                              = [tex]\sqrt[3]{\frac{\text{volume of large prism}}{\text{Volume of small prism}}}[/tex]

                                              = [tex]\sqrt[3]{\frac{125}{27} }[/tex]

                                              = [tex]\frac{5}{3}[/tex]

                                              = 5 : 3

Therefore, scale factor of  cube to the smaller cube is 5 : 3.

Answer:

Domain: ​(−∞, 0) ∪ (0, ∞)​; Range: (−∞, 0) ∪ (0, ∞)

Step-by-step explanation:

See attachment.

We want to find the domain and range of the function [tex]f(x)=\frac{3}{5} x^5[/tex].

The domain is the set of all possible x-values that are included in the function, while the range is the set of all possible y-values that are included in the function.

Look at the graph.

We can see that the x-values can go into infinity except when approaching the line x = 0. Here, the function will never touch x = 0 because that would make the graph undefined. So, we can say that the domain is all real numbers except for x = 0, or ​(−∞, 0) ∪ (0, ∞).

It's the same thing with the y-values. Although it looks like the line is touching the y-axis, or the line y = 0, the graph actually is not - it's just going really close to it. So, the range is again ​(−∞, 0) ∪ (0, ∞).

Thus, the answer is D.

Answer:

Last one

Domain: ​(−∞, 0)∪ (0, ∞)​ Range: (−∞, 0)∪ (0, ∞)

Step-by-step explanation:

f(x) = 3/(5x⁵)

Since x is in the denominator, x can not be 0

Domain: all real values of x except 0

For y = 0, x has to be infinite therefore y can not be 0

Range: all real values except 0

Answer:

xy and bc is parallel

70 degrees

Step-by-step explanation:

a) it's a rule

b) since angle xbc is 55 degrees, angle xcb must also be 55 degrees as it's a isoceles triangle. then you would take 180 degrees to subtract the sum of angle xcb and xbc which would give you 70 degrees

Step-by-step explanation:

Took the test.

Based on the information given regarding the triangle, the triangle pairs can be mapped to each other will be D. Triangles X Y Z and A B C are shown. Both triangles are congruent. Triangle X Y Z is rotated down and to the left to form triangle A B C. It is also slightly higher than triangle A B C.

It should be noted that a translation is a slide, and this implies that the function has the same shape graphically, but on the other hand, the graph of the function slides to a different position on the coordinate plane.

In this case, the triangle pairs can be mapped to each other using both a translation and a rotation about C. Therefore, the correct option is D.
