Answer:
1. No.
2. No.
3. No.
4. Yes.
Step-by-step explanation:
You just need to sub in the numbers for x and y. For the first one, it is -21 - 8 > 18 which is equal to -29 > 18, so the answer is no. For the second one, it is -21 > 18, so the answer is no. For the third one, it is -14 + 32 > 18 which is equal to 18 > 18, so the answer is no. For the fourth one, it is 56 - 36 > 18 which is equal to 20, so the answer is yes.

What does it mean to divide figures into known shapes
Dividing figures into known shapes in mathematics helps simplify complex shapes and analyze their properties effectively.
Dividing figures into known shapes involves breaking down complex figures into simpler, identifiable shapes such as squares, rectangles, triangles, or circles.
This process is commonly used in geometry to analyze and understand the properties of irregular shapes by partitioning them into known geometric shapes.
By dividing figures into known shapes, mathematicians can apply specific formulas and principles to calculate areas, perimeters, and other geometric attributes accurately.
A gardener is planting two types of trees:
Type A is 8 feet tall and grows at a rate of 6 inches per year.
Type B is 10 feet tall and grows at a rate of 4 inches per year.
Algebraically determine exactly how many years it will take for these trees to be the same height.
Answer:
12 years
Step-by-step explanation:
8 feet = 96 inches
10 feet = 120 inches
96 + 6t = 120 + 4t
2t = 24
t = 12

At certain times of the year, about 70% of airline flight delays are caused by bad weather. During those times, about 50% of all flights experience bad weather, and about 25% of all flights are delayed.
Given these percentages, if the weather is good, what is the probability that your flight will be delayed?
About 35%
About 20%
About 15%
Answer:
About 15%
Step-by-step explanation:
Since the weather is good, this means that 500 flights are affected because 50% of the flights experience good weather and 50% of the flights experience bad weather.
there will be 75 flights that are delayed due to causes other than bad weather
if you assume that all of the flights that are not caused by bad weather occur in good weather, then the probability would have to be 75 / 500 = .15 = 15%.
Answer:
I believe is 35%
Step-by-step explanation:
April rewrote a quadratic function in vertex form.
h(x) = 5x2 – 30x + 30
Step 1: h(x) = 5(x2 - 6x+ + 30
Step 2: h(x) = 5(x2 - 6x + 9) + 30 – 45
Step 3: h(x) = 5(x - 3)2 + 15.
April said that the vertex is (3, 15). Is April correct?
April correctly transformed the quadratic function into vertex form, and the resulting vertex is (3, 15), as determined by the completion of the square method.
Explanation:April is indeed correct about the vertex of the function h(x). The vertex form of a quadratic function is h(x) = a(x - h)^2 + k, where the point (h, k) is the vertex of the parabola. April has rewritten the quadratic function h(x) = 5x^2 - 30x + 30 into vertex form as h(x) = 5(x - 3)^2 + 15, indicating that the vertex is at (3, 15). This can be verified through the completion of the square method, where a perfect square trinomial is created by adding and subtracting the appropriate constant term. April added and subtracted 9 inside the parentheses, which is (6/2)^2, to keep the equation equivalent. Finally, she factored out the coefficient of the quadratic term (5) before completing the square, which is correct.
What is the volume of a cube on which each face has a diagonal of 12.8 inches? (round to nearest tenth)
A) 741.2 in3
B) 1,048.6 in3
C) 1,482.9 in3
D) 2,097.2 in3
Final answer:
To find the volume of a cube with each face diagonal of 12.8 inches, calculate the side length using the diagonal length, then find the cube volume using the side length cubed. The volume is approximately 741.2 cubic inches.
Explanation:
Volume of a Cube:
To find the volume of a cube where each face has a diagonal of 12.8 inches, we first need to calculate the length of a side of the cube using the diagonal length. The formula for the diagonal of a face of a cube is √2 times the side length. Thus, side length = diagonal length / √2. Then, we can find the volume of the cube by cubing the side length.
Calculation:
Side length = 12.8 / √2 = 9.04 inchesVolume = [tex](9.04)^3[/tex] = 741.2 cubic inchesWhat is the value of y, given x=6 and the equation y= 0.5x + 7

The fish population of Lake Collins is decreasing at a rate of 5% per year. In 2001 there were about 1,200 fish. Write an exponential decay function to model this situation. Then find the population in 2006.
The student's question involves creating an exponential decay function to determine the fish population in Lake Collins after five years, given a starting population in 2001 and a 5% annual decrease. The function is N(t) = 1200e^-rt, with r being 0.05 and t being 5. The estimated fish population for the year 2006 is approximately 935.
The student is asking for an exponential decay function to model the decrease in the fish population at Lake Collins. We are given that in 2001, there were about 1,200 fish, and the fish population is decreasing at a rate of 5% per year. To model this situation, we use the exponential decay formula:
N(t) = N0e-rt
Where:
N(t) is the fish population at time tN0 is the initial fish populationr is the decay rate (as a decimal)t is the time in years since the initial countFor this problem, the initial population N0 is 1,200, the decay rate r is 0.05 (since 5% is 0.05 as a decimal), and the time t we are interested in is 2006 - 2001 = 5 years. Plugging these values into the formula, we get:
N(5) = 1200e-0.05 * 5
Calculating N(5), the fish population in 2006, using the above formula:
N(5) = 1200e-0.25 ≈ 1200 * 0.7788 ≈ 935
Therefore, the estimated fish population in Lake Collins in 2006 would be approximately 935 fish.

A rectangular prism has a length of 10.4 millimeters, a width of 5 millimeters, and a height of 8 millimeters.
Please answer ASAP! I've been stuck on this problem for hours.
Answer:
[tex]V=416\ mm^3[/tex]
Step-by-step explanation:
we know that
The volume of a rectangular prism is given by the formula
[tex]V=LWH[/tex]
we have
[tex]L=10.4\ mm\\W=5\ mm\\H=8\ mm[/tex]
substitute in the formula
[tex]V=(10.4)(5)(8)=416\ mm^3[/tex]
The volume of the rectangular prism is [tex]416\ mm^3[/tex]
Calculation of the volume of the rectangular prism:Since A rectangular prism has a length of 10.4 millimeters, a width of 5 millimeters, and a height of 8 millimeters.
So here the volume is
= (10.4) (5) (8)
= [tex]416\ mm^3[/tex]
Here we multiplied all three things to get the volume
hence, The volume of the rectangular prism is [tex]416\ mm^3[/tex]
