A rocket is dropping to the moons surface at a constant rate of 15 feet per second. After 2 minutes of descent the rocket is at a height of 11,400 feet above the moons surface. At what elevation in feet was the rocket when it started to drop to the moons surface?
Answer:
13,200 feet
Step-by-step explanation:
So, the rocket starts descending at a given rate and time, so we first need to find the length it passed during that descent.
Length equals to speed multiplied with time:
s = v • t
since speed is given in feet per second, we need to convert minutes to seconds; if one minute has 60 seconds, then two minutes have 120 seconds.
s = 15 feet/s • 120 s
s = 1800 feet
So, the rocket descended 1800 feet, but it still has 11,400 feet to the Moon's surface. That means that the rocket was on 11,400 + 1,800 = 13,200 feet elevation when it started to drop.
P=v/1+kM^-t solve for k
Answer: [tex]k=\frac{M^t(v-P)}{P}[/tex]
Step-by-step explanation:
Given the following equation provided in the exercise:
[tex]P=\frac{v}{1+kM^{-t}}[/tex]
You can follow these steps in order to solve for "k":
1. You must multiply both sides of the equation by [tex]1+kM^{-t}[/tex]:
[tex](P)(1+kM^{-t})=(\frac{v}{1+kM^{-t}})(1+kM^{-t})\\\\P+PkM^{-t}=v[/tex]
2. The next step is to subtract "P" from both sides of the equation:
[tex]P+PkM^{-t}-(P)=v-(P)\\\\PkM^{-t}=v-P[/tex]
3. Now apply the Negative Exponent Rule, which states that:
[tex]a^{-n}=\frac{1}{a^n}[/tex]
Then:
[tex]\frac{Pk}{M^{t}}=v-P[/tex]
4. Multiply both sides of the equation by [tex]M^t[/tex]:
[tex](M^t)(\frac{Pk}{M^{t}})=(M^t)(v-P)\\\\Pk=M^t(v-P)[/tex]
5. And finally, you must divide both sides of the equation by "P":
[tex]\frac{Pk}P=\frac{M^t(v-P)}{P}\\\\k=\frac{M^t(v-P)}{P}[/tex]

At the grocery store, Lily spent $m$ dollars on milk, twice that amount on fruit, and $6$ dollars less than $3$ times the amount spent on milk for bread. If she entered the store with $\$80$, how much money did she have when she left? Write your answer in terms of $m$.
Answer:
$remaining=86-6m
Step-by-step explanation:
$remaining = 80 - (m + 2m) - (3m-6)
$remaining = 80 - 3m - 3m +6
$remaining = 86 - 6m
80 -> total amount she brings into the store
m -> money spent on milk
2m -> money spent on fruit (two x m)
3m-6 -> bread (six dollars less than three times the milk value)
Simplify and the result is 86-6m
Jade buys a blouse and a skirt for 3/4 of their original price. Jade pays a total of $31.50 for the two items. What is the original price of the skirt?
Answer:
The original price of the skirt is $24
Step-by-step explanation:
The complete question is
Jade buys a blouse and a skirt for 3/4 of their original price. Jade pays a total of $31.50 for the two items. If the original price of the blouse is $18, what is the original price of the skirt?
Let
x ----> the original price of the blouse
y ---> the original price of the skirt
we know that
Three fourth of the sum of the original price of the blouse and the original price of the skirt, must be equal to the total paid for the two items
so
The linear equation that represent this situation is
[tex]\frac{3}{4}(x+y)=31.50[/tex]
we have
[tex]x=18[/tex] ----> given problem
substitute the value of x in the expression above and solve for y
[tex]\frac{3}{4}(18+y)=31.50\\[/tex]
Multiply by 4 both sides
[tex]3(18+y)=4(31.50)\\54+3y=126\\3y=126-54\\3y=72\\y=24[/tex]
therefore
The original price of the skirt is $24

My answer is 5 but not quite sure.
36 in by 8in by 10 in = volume of 2880 cubic inches. With that said, Piper wants to plot enough soil to hold a total volume of 2880 cubic in.
Since 1 bag contains 576 cubic in, we can see that 576 cubic x 5 = 2880.
Or the number of bags into 2880
Then 2880 cubic in divided by 576 cubic. 5
Answer:
5
Step-by-step explanation:
We gonna multiply the 36 inches long, 8 inches wide and 10 inches tall and divide it by no of bag (576)
Rewrite 4^5=1024 as a logarithmic equation.
To rewrite the equation 4^5 = 1024 as a logarithmic equation, we use the definition of a logarithm to get log4(1024) = 5, which indicates that 4 raised to the power of 5 equals 1024.
Explanation:To rewrite the exponential equation 4^5 = 1024 as a logarithmic equation, we need to apply the definition of a logarithm which states that if b^y = x, then logb(x) = y. In this case, our base (b) is 4, the exponent (y) is 5, and the result (x) is 1024. Therefore, the equivalent logarithmic equation is log4(1024) = 5.
Remember that a logarithm essentially answers the question: To what exponent must the base be raised to produce a given number? Here, we are saying that 4 must be raised to the power of 5 to get 1024. This transformation from an exponential to a logarithmic form is a fundamental concept in mathematics, particularly when dealing with logarithmic scales and operations.

Nathan drew a scale drawing of a hotel. A room in the hotel is 55 inches long in the drawing. The actual room is 22 feet long. What scale did Nathan use?
Answer:
Nathan use scale of 5 inches : 2 feet.
Step-by-step explanation:
Given:
Nathan drew a scale drawing of a hotel.
A room in the hotel is 55 inches long in the drawing.
The actual room is 22 feet long.
Now, to find the scale Nathan use.
The scale drawing of room = 55 inches.
The actual room = 22 feet.
Now, to get the scale Nathan use we set the ratio:
The scale drawing of room : The actual room.
= [tex]55\ inches:22\ feet[/tex]
[tex]=\frac{55}{22}[/tex]
[tex]=\frac{5}{2}[/tex]
[tex]=5\ inches:2\ feet.[/tex]
Therefore, Nathan use scale of 5 inches : 2 feet.
The scale factor Nathan used is 2/5.
Explanation:To find the scale factor, we can set up a proportion using the length in the drawing and the actual length. Let x represent the scale factor. The proportion can be set up as follows:
55 inches / 1 = 22 feet / x
Cross multiplying, we get:
55 * x = 1 * 22
Simplifying, we have:
x = 22 / 55 = 2 / 5
Therefore, the scale factor Nathan used is 2/5.

Line b passes through the Point(-3, -4) and has a slope of -1/2. What is the equation of Line b in standard form?
x + 2y = -11
x + 2y = -10
2x + y = -11
2x + y = -10
Answer:
[tex]x+2y=-11[/tex]
Step-by-step explanation:
Slope intercept form of a line is given by:
[tex]y=mx+b[/tex]
Where
m is the slope and b is the y-intercept
Given slope is [tex]-\frac{1}{2}[/tex]
We can write:
[tex]y=-\frac{1}{2}x+b[/tex]
Now to find b, we replace x with -3 and y with -4, given, so we have:
[tex]y=-\frac{1}{2}x+b\\-4=-\frac{1}{2}(-3)+b\\-4=\frac{3}{2}+b\\b=-5.5[/tex]
So, the equation is:
[tex]y=-\frac{1}{2}x-\frac{11}{2}[/tex]
Now,
The standard form is given by:
[tex]Ax+By=C[/tex]
So, we take x and y to left side and the constant to right side. Rearranging, we get:
[tex]y=-\frac{1}{2}x-\frac{11}{2}\\2y=-x-11\\x+2y=-11[/tex]
The first answer choice is right.
Final answer:
The equation of line b that passes through the point (-3, -4) and has a slope of -1/2 in standard form is x + 2y = -11.
Explanation:
To find the equation of line b that passes through the point (-3, -4) and has a slope of -1/2, we will start with the slope-intercept form of a line equation y = mx + b, where m is the slope and b is the y-intercept. While we know the slope (-1/2), we do not yet have the y-intercept. We can use the given point to solve for b. Plugging the point into the equation gives -4 = (-1/2)(-3) + b, which simplifies to -4 = 3/2 + b. Solving for b yields b = -11/2.
Now we have the slope-intercept form of the line: y = (-1/2)x - 11/2. To convert this to standard form, which is Ax + By = C, we multiply through by 2 to clear the fractions, which gives us 2y = -x - 11. Rearranging this, we add x to both sides to get x + 2y = -11. Therefore the correct equation in standard form is x + 2y = -11.

If the numerator and denominator of a fraction are both prime numbers and are not equal to each other, can the fraction be simplified?
Answer:
No, primes cannot be divided by anything else then the number itself and one. Therefor you cannot divide it by any other prime.
Final answer:
A fraction with a numerator and denominator that are both prime numbers and different from each other cannot be simplified because there are no common factors to remove, as prime numbers only have 1 and themselves as factors.
Explanation:
If the numerator and denominator of a fraction are both prime numbers and are not equal to each other, the fraction cannot be simplified further. This is because prime numbers have only two factors: 1 and themselves. To simplify a fraction, you would prime factorize both the numerator and the denominator and then remove any common factors found in both.
However, since prime numbers have no other factors besides 1 and the number itself, and the two primes in our fraction are not equal, there are no common factors to remove. For example, in the fraction ⅓, both 3 and 5 are prime and there is no number other than 1 that can divide both. Hence, ⅓ is already in its simplest form.

Write a minor function for the line with the slope of -5 that passes through points (7,3)
The equation of the line is [tex]5x+y-38=0[/tex]
Step-by-step explanation:
The slope is [tex]m=-5[/tex]
Also, the line passes through the points [tex](7,3)[/tex]
To find a line with slope [tex]m=-5[/tex] that passes through the points [tex](7,3)[/tex], let us use the equation of a line with slope that passes through the point is given by [tex](y-y_{1} )=m(x-x_{1} )[/tex] where m is the slope and [tex](x_{1} ,y_{1} )[/tex] are the points [tex](7,3)[/tex].
Thus, substituting the values in the equation of a line, we get,
[tex](y-3)=-5(x-7)[/tex]
Multiplying the term [tex](x-7)[/tex] by -5, we get,
[tex]y-3=-5 x+35[/tex]
Adding both sides by 5x,
[tex]5x+y-3=35[/tex]
Subtracting 35 from both sides of the equation,
[tex]5x+y-38=0[/tex]
Thus, the equation of the line is [tex]5x+y-38=0[/tex]

The perimeter of a retangular field is 294 yards. If the width of the field is 64 yards what is the length?
Answer:
83 yards
Step-by-step explanation:
We are given;
Perimeter of rectangle is 294 yards Width is 64 yardsWe are required to determine the length;
we need to know how to get the perimeter of the rectangle;Perimeter = 2( length + width)That is;
P = 2 (L + W)
P = 2L + 2W
Rearranging the formula;
2L = P - 2W
Therefore;
2L = 294 yards - 2 (64 yards)
= 294 - 128
= 166
L = 166 ÷ 2
= 83 yards
Thus, the length of the rectangle is 83 yards.

Solve this exercise using the fact that the sum of the measures of the three angles of a triangle is 180degrees°.
In a triangle, the measures of the three angles are x, x+14, and x−38. What is the measure of each angle
Answer:
68°, 82°, and 30°
Step-by-step explanation:
x+x+14+x-38=180
combine like terms
3x-24=180
put variables on one side
3x=204
divide
x=68
substitute
x=68
x+14=82
x-38=30
By using the triangle angle sum theorem, we find that the measures of the angles of the triangle in question are 68 degrees, 82 degrees, and 30 degrees.
Explanation:This question involves using the fact that the sum of internal angles in any triangle totals 180 degrees. In this triangle, the three angles are given as x, x+14, and x-38. To find the measures of these angles, we set up the below equation:
x + (x+14) + (x−38) = 180
The step above incorporates the triangle angle sum theorem. Now we simplify and solve for 'x':
3x - 24 = 180
3x = 204
x = 68
So the measure of the angles in the triangle are 68 degrees, 82 degrees, and 30 degrees.
