Answer:
Step-by-step explanation:
Along with the angle of elevation, the initial velocity of the ball will determine how far and how high it goes.
Also, the initial height that the ball is hit from, as well as the horizontal distance from the fence, will affect whether the ball clears the fence.
There's also the acceleration of gravity, but here on Earth, that doesn't change much near the surface.
The equation T^2=A^3 shows the relationship between a planet’s orbital period, T, and the planet’s mean distance from the sun, A, in astronomical units, AU. If the orbital period of planet Y is twice the orbital period of planet X, by what factor is the mean distance increased?
2^1/3
2^1/2
2^2/3
2^3/2
Thank you!
Answer:
2^3/2
Step-by-step explanation:
The question is on formulae variation
Given T²=A³.....................the relationship between a planet’s orbital period, T, and the planet’s mean distance from the sun, A
Making T subject of the formulae
T²=A³.............................square root both sides
T= √A³ OR (A³)^1/2
if the orbital period of planet Y is twice the orbital period of planet X then,
Y=2T
Y=2× √A³
Y=2×(A³)^1/2
Applying the laws of indices
Y=2×(A)^(3×1/2)
Y=2×(A)^3/2
Compare
A^3/2 and 2A^3/2
The mean distance increased by 2^3/2
Which of the following comparisons is FALSE?
a. 4 liters < 1 gallon b. 1 foot < 1 meter c. 25 grams < 1 ounce d. 10 kilometers < 9 miles
Answer:
A
Step-by-step explanation:
Let's check each one-by-one.
a.
we know 3.79 liters is 1 gallon, so 4 liters IS NOT LESS THAN 1 gallon
THis is false.
b.
We know 1 feet is 0.30 meters, so definitely 1 foot is less than 1 meter.
This is true.
c.
we know around 28.35 grams is 1 ounce, so definitely 25 grams is less than 1 ounce.
THis is true.
d.
We know 1 km is approximately 0.62 miles so 10 km would be around 0.62*10 = 6.2 miles
So definitely 9 miles IS GREATER than 10 km.
THis is true.
So answer choice A is false, only.

The sum of two numbers is 13. Two times the first number minus three times the second number is one. If you let x stand for the first number and y for the second number what are the two numbers?
please and thanks!
Answer: X = 8 And Y = 5 "First Choice Letter A"
Step-by-step explanation: x + y = 13......x = 13 - y
2x - 3y = 1
2(13 - y) - 3y = 1
26 - 2y - 3y = 1
-2y - 3y = 1 - 26
-5y = -25
y = -25/-5
y = 5
x + y = 13
x + 5 = 13
x = 13 - 5
x = 8
so, x = 8 and y = 5

Answer: I think the answer is the second box.
Step-by-step explanation: It says 20 males have watched the show. I hope I helped you. If I am wrong, tell me in a polite way. :D
Hello there! The answer is the second chart, or B.
To find the answer, look at the parts of the question.
Let's start in the beginning. Note how it says "Of the 80 participants, 30 were male and 50 were female". This means that, looking at the options, in the "total" row, there should be a value for "30" by male, "50" by female and 80 at the bottom. This means that it cannot be A since this option says that there were 80 females and 80 males and 160 total, or C since it says there are 80 males and 55 females with a total of 135.
Next, it says that 45 have watched the show and 35 have not. If you look at the options left B and D, the only one the has these numbers for have and have not watched is B, making this the correct answer.
I hope this helps and have a great rest of your day! :)

The scale used in the drawing is = 1 foot. B. On the scale drawing, the width of the sandbox is inches. C. If Mr. Cooper decides to make a new scale drawing of the playset, in which he uses a scale of inch = 1 foot, all of the dimensions in the old drawing will be multiplied by a factor of .
Answer:
If Mr. Cooper decides to make a new scale drawing of the play set, in which he uses a scale of inch = 1 foot, all of the dimensions in the old drawing will be multiplied by a factor of ⇒ the last answer
Step-by-step explanation:
* Lets study what is the meaning of the scale factor
- To find a scale factor between two similar figures
# Find two corresponding sides and write the ratio of the two sides.
# If you begin with the smaller figure, your scale factor will be less
than one.
# If you begin with the larger figure, your scale factor will be greater
than one
* Now lets solve the problem
- The rectangular sandbox, has a length of 5 feet and a width of
7 feet
- On the scale drawing, the length of the sandbox is 2 inches
- The actual sandbox and the drawing sandbox are similar
∵ The length of the actual sandbox is 5 feet
∵ The drawing length is 2 inches
∵ 1 foot = 12 inches
∴ The scale factor is 2/(5 × 12) = 1/30
* That means each actual dimensions will multiply by 1/30 to find
the drawing dimensions
∴ The drawing length of the sandbox = 5 × 12 × 1/30 = 2 inches
∴ The drawing width of the sandbox = 7 × 12 × 1/30 = 2.8 inches
* All of the dimensions in the old drawing will be multiplied by
a factor of 1/30

35 weeks
Step-by-step explanation:
She already has 24 dollars saved, but will save 3 dollars every week. Use x to represent the number of weeks. In total she will save 129.
Solve for x using the equation:
24-24 + 3x = 129-24
3x = 105
3x/3 = 105/3
x= 35
volume of this prism
The volume is (area of cross-section) x (length) .
-- The cross-section is a triangle. The area of a triangle is
Area = (1/2) (base) (height) .
In this one, the base is 9/4 m and the height is 3-1/3 m .
Area = (1/2) (9/4 m) (3-1/3 m)
Area = (1/2) (9/4) (10/3)
Area = 90/24 m² .
-- Volume = (area of cross-section) x (length)
Volume = (90/24 m²) x (7-1/3 m)
Volume = (90/24) x (22/3) m³
Volume = (1,980 / 72) m³
Volume = 27.5 m³

You randomly select one card from a 52-card deck. Find the probability of selecting the four of spades or the six of diamonds.
Answer:
1/26
Step-by-step explanation:
There's only 1 four of spades and only 1 six of diamonds. So the probability is:
P = P(4 of spades) + P(six of diamonds)
P = 1/52 + 1/52
P = 1/26
The probability of selecting the four of spades or the six of diamonds from a standard 52-card deck is 1/26. This is determined by adding the probabilities of each individual card being drawn since they are mutually exclusive events.
Explanation:The question asks about the probability of selecting a specific card from a standard 52-card deck. To find the probability of selecting either the four of spades or the six of diamonds, we recognize that these are two distinct events. Since there is one four of spades and one six of diamonds in a deck, and there are 52 cards in total, the probability of drawing the four of spades is 1/52 and similarly the probability of drawing the six of diamonds is also 1/52. These events are mutually exclusive, meaning they cannot happen at the same time, so we can simply add the two probabilities together to find the total probability:
Probability(four of spades or six of diamonds) = Probability(four of spades) + Probability(six of diamonds) = 1/52 + 1/52 = 2/52.
Therefore, the probability is 2/52, which can be simplified to 1/26.

The sequence is recursive. Find the value of the next term in the sequence 7, 1, -5, -11, -17,
Answer:
-23
Step-by-step explanation:
Each term is 6 less than the past term. Hopw this helps!
There is no "standard" way to solve an exercise like this: you just have to eyeball the sequence and try to find/guess the pattern.
The most common (and easy!) examples are arithmetic or geometric sequence, where the difference or ratio between two consecutive terms is constant.
This is one of those cases: this is an arithmetic sequence, because you obtain every next term by subtracting 6 from the previous one:
[tex]a_1 = 7\\a_2 = a_1-6 = 7-6 = 1\\a_3 = a_2-6 = 1-6 = -5\\a_4 = a_3-6 = -5-6 = -11\\a_5 = a_4-6 = -11-6 = -17[/tex]
So, we can deduce
[tex]a_6 = a_5-6 = -17-6 = -23[/tex]

[tex]m\angle LMW=\frac{1}{2}[arc\ LK+arc\ WK][/tex]
substitute the given values
[tex]m\angle LMW=\frac{1}{2}[66\°+68\°]=67\°[/tex]
Applying the inscribed angle theorem, the measure of angle LMW is found as: 67°.
What is the Inscribed Angle Theorem?According to the inscribed angle theorem, the measure of an inscribed angle is half the measure of the arc that is intercepted.
Given:
m(LM) = 164°m(WK) = 68°m∠MLK = 65°Find m(MK):
m(MK) = 2(m∠MLK) (inscribed angle theorem)
Substitute
m(MK) = 2(65°)
m(MK) = 130°
Find m(LK):
m(LK) = 360° - m(LM) - m(MK) (full circle)
Substitute
m(LK) = 360° - 164° - 130°
m(LK) = 66°
Therefore:
m∠LMW = 1/2[m(LK) + m(WK) (inscribed angle theorem)
Substitute
m∠LMW = 1/2[66° + 68°]
m∠LMW = 1/2[134°]
m∠LMW = 67°
