10. The Earth’s escape speed (the speed you need to get away forever) is about 25,000 miles per hour. Escape speed depends on the gravity of the object trying to hold the spacecraft from escaping. Based on your understanding of gravity, how will the escape speed from the Moon compare to the escape speed from Earth?
a. The Moon’s escape speed will be greater than Earth’s
b. The Moon’s escape speed will be smaller than Earth’s
c. The Moon’s escape speed will be exactly the same as Earth’s
d. The Moon’s escape speed will change depending on whether it’s a crescent Moon or a full Moon
e. The Moon’s escape speed will be balanced by the Earth being so close and it will be zero
Kaylee has a 7/12 yard piece of lace that she is using to make doll dresses. She
needs 1/8 yard for each dress. Which expression can be used to show how
many dresses she can make from the lace?
The expression that can be used to show how many dresses she can make from the lace is [tex]\frac{7}{12}[/tex] ÷[tex]\frac{1}{8}[/tex]
In order to determine how many dresses can be made from the lace, divide the yards of the lace by how many yards are needed to make the dress
Number of dresses that can be made = [tex]\frac{7}{12}[/tex] ÷ [tex]\frac{1}{8}[/tex]
Solving this equation, 4 dresses can be made from the lace
7/12 x 8/1 = 4.67 dresses

Since our denominators of 3 and 2 have no factors in common,
our least common denominator is 3 · 2 or 6.
In order to get a denominator of 6 in each fraction,
we multiply top and bottom of the first fraction by 2
and top and bottom of the second fraction by 3.
That gives us -4/6 + 3/6 which simplifies to -1/6.

Answer:
x = 5Step-by-step explanation:
Given,
Perimeter of a triangle = 75
One side of the triangle = 5x
Therefore,
By the problem,
5x + 5x + 5x = 75
=> 15x = 75
=> x = 75/15
=> x = 5 (Ans)

Answer:
(i) 55.59 km/h
(ii) 3600 nautical miles ≈ 6670.8 km
(iii) 30°N 29.3°E
Step-by-step explanation:
(i) The speed in km/h requires a units conversion.
(30 kt/h)(1.853 km/kt) = 55.59 km/h
__
(ii) Here, we assume we're interested in the distance traveled. If the course is "due east", we presume that means it follows the 30° latitude line, so is not the shortest route between A and B. That is, the distance from A to B will be different from the distance traveled. (The shortest route from A to B is along a great circle.)
distance = speed × time
distance = (30 kt/h)(120 h) = 3600 nautical miles
= (55.59 km/h)(120 h) = 6670.8 km
__
(iii) The radius of the 30° latitude line is ...
(6370 km)(cos(30°)) = 3185√3 km ≈ 5516.58 km
The relationship between arc length (s) and central angle (α) is ...
s = rα
So, the change in the vessel's longitude is ...
α = (6670.8 km)/(5516.58 km) ≈ 1.20923 radians ≈ 69.28°
Then town B has longitude ...
40°W -69.3° = -29.3°W = 29.3°E
The position of town B is about 30°N 29.3°E.

Her jump rope Ella can make 17 jumps in 15 second.at this rate how make jumps can she make in20 minute?
Answer:
1360
Step-by-step explanation:
there are 1200 seconds in 20 minutes. if Ella can do 17 jumps in 15 seconds, you would divide 1200 by 15 (which equals 80) because that would be the number of 15 seconds in 20 minutes. then you would divide 80 by 17, which gives you your final answer of 1360 jumps in 20 minutes.

According to data, as education level increases the unemployment rate decreases. This is an example of
what type of correlation?
As education level increases the unemployment rate decreases this is a negative linear type correlation.
What are the main types of correlation ?There are three main types of correlations they are positive linear correlation where both the variables related to each other increase or decrease simultaneously.
In negative linear correlation between two variables if one variable is increasing the other starts to decrease and vice versa and the third type of correlation is where there is no correlation increase and decrease happen in random way that is quite difficult to form in terms of numerical form or graphing them.
According to the given statement as education level increases the unemployment rate decreases.
This is an example of negative linear correlation as one variable increases the other related to it decreases.
Increase in education level decreases unemployment as with higher education people learn new skills,they become more aware of their surroundings and most importantly education teaches us to think logically these are the things that a co-operate world wants.

Step-by-step explanation:
The question is asking the amount invested in fund B. We can let 'b' represent that amount. Then the amount invested in fund A is (6000-b). The total profit from the investments is ...
0.02(6000 -b) +0.07(b) = 0.04(6000)

Katarina asks Dacia how she can you derive the formula r= x2+y2. Which of Dacia's replies are correct?
Options A and B are correct. If Katarina asks Dacia how she can derive the formula r= x²+y², then the following statements should be Dacia's reply.
Because r is the hypotenuse of a right triangle, with legs x and y, you can use the Pythagorean theorem to determine 'rr is a straight line distance from the point and can be projected onto x and y axes where x = rcosθ, y = rsinθ. Writing sinθ = y/r, Cosθ = x/r and using the identity sin²θ+cos²θ = 1Given the equation by Katarina expressed as:
r = √x²+y²
One of the ways Katarina can derive the equation is to use the Pythagoras theorem which states that the sum of the square of the hypotenuse is equal to the sum of the other two sides. Let:
r be the length of the hypotenuse
x and y be the other two sides
According to the theorem:
r² = x² + y²
Take the square root of both sides
√r² = √x² + y²
r = √x² + y²
Also, Katarina can use the trigonometry identity. According to a right triangle where:
sinθ = y/r
Cosθ = x/r
According to trigonometry identity, sin²θ+cos²θ = 1
(y/r)² + (x/r)² = 1
y²/r² + x²/r² = 1
(y²+x²)/r² = 1
y²+x² = r²
Swap
r²=y²+x²
This shows that the first two options are correct.
Because r is the hypotenuse of a right triangle, with legs x and y, you can use the Pythagorean theorem to determine 'r
r is a straight line distance from the point and can be projected onto x and y axes where x = rcosθ, y = rsinθ. Writing sinθ = y/r, Cosθ = x/r and using the identity sin²θ+cos²θ = 1
