-. The side views of two different ramps are shown below. Which is a true
tatement about the slope of the ramps?
The statement that is true about the slope of the ramps is: A. Slope of ramp A = slope of ramp B.
What is the Slope?Slope = gradient = rise / run = vertical distance / horizontal distance.
Slope of the side view of ramp A = rise / run = 20 / 30 = 2/3.
Slope of the side view of ramp B = rise / run = 14 / 21 = 2/3.
The slope of A = slope of B = 2/3
The statement that is true of the slopes of both ramps is therefore: A. Slope of ramp A = slope of ramp B.

Answer:
(30x⁴+36x²y⁴)+(36x⁴y²+30xy⁴).
Step-by-step explanation:
x⁶+3x⁴y⁴+xy⁶
1) df/dx=6x⁵+12x³y⁴+y⁶; d²f/dx²=30x⁴+36x²y⁴;
d²f/(dxdy)=48x³y³+6y⁵ (note, d²f/(dxdy)=d²f/(dydx) !!);
df/dy=12x⁴y³+6xy⁵; d²f/dy²=36x⁴y²+30xy⁴;

In order to solve the following system of equations by subtraction, which of
the following could you do before subtracting the equations so that one
variable will be eliminated when you subtract them?
4x - 2y=7
3x - 3y=15
A. Multiply the top equation by 15 and the bottom equation by 7.
B. Multiply the top equation by-3 and the bottom equation by 2.
O C. Multiply the top equation by 3 and the bottom equation by 4.
Can someone help me
Answer:
B. Multiply the top equation by-3 and the bottom equation by 2.
Step-by-step explanation:
-3(4x-2y=7)
2(3x-3y=15)
-12x + 6y= -21
6x - 6y = 30
6y and -6y both cancel each other out which gives us 0 when -3 is multiplied by the top and the bottom is multiplied by 2, which gives us the answer B.

Select the correct answer. Which sentence correctly describes a data set that follows a normal distribution with a standard deviation of 4 and a mean of 14? A. 68% of the data points lie between 10 and 14. B. 68% of the data points lie between 8 and 12. C. 68% of the data points lie between 10 and 18. D. 68% of the data points lie between 10 and 16.
Answer: Option (c) is correct.
68% of the data points lie between 10 and 18.
Step-by-step explanation: Given : a normal distribution with a standard deviation of 4 and a mean of 14
We have to choose the sentence that correctly describes a data set that follows a normal distribution with a standard deviation of 4 and a mean of 14.
Since, given 68% data.
We know mean of data lies in middle.
And standard deviation is distribute equally about the mean that is 50% of values less than the mean and 50% greater than the mean.
So, 68% of data lies
mean - standard deviation = 14 - 4 = 10
mean + standard deviation = 14 + 4 = 18
So, 68% of the data points lie between 10 and 18.

find the prime factorization of the following number 252?
Answer:
2,3,7 are the prime factorization of number of 252
Hi Student!
Prime factorization is the process of stripping down a number to it's basic elements. We take a number and bring it down the most we can. For example we take 4 and make it 2 x 2. In this case we are given a number of 252 so we can began by dividing by 2.
[tex]252 / 2[/tex]
[tex]126[/tex]
Looking at the numbers that we have now, 126 x 2, we can see that 126 can still be divisible by another 2 so lets do that again.
[tex]126 / 2[/tex]
[tex]63[/tex]
Now, looking at the numbers that we have, 63 x 2 x 2, we see that we can no longer divide it by a 2 because 63 is not divisible by 2. However, we can divide 3 away from the number so lets do that.
[tex]63 / 3[/tex]
[tex]21[/tex]
Once again, looking at the numbers that we have, 21 x 3 x 2 x 2, we see that we can once again divide a 3 away from our first number so lets do that again.
[tex]21 / 3[/tex]
[tex]7[/tex]
Finally, we have come down to the last line where our final elements are 7 x 3 x 3 x 2 x 2. This is our prime factorization of the number 252 and this is where we can conclude our solution seeking.

6x - 4= -4(X-5)
What value of x makes the equation true?
Answer:
Step-by-step explanation:
Equation 6x - 4= -4(X-5) Remove the brackets
Solution
6x - 4 = -4x + 20 Add 4x to both sides
6x + 4x -4 = -4x+4x + 20 Combine
10x - 4 = 20 Add 4 to both sides
10x - 4 + 4 = 20 + 4 Combine
10x = 24 Divide by 10
10x/10 = 24/10

If you know that a student receives financial aid,
what is the probability that the student is a
graduate student?
Answer: Answer:
The probability that a given student is a graduate, given that he or she is on financial aid, is 30.8%.
Step-by-step explanation:
To determine what is the probability that a given student is a graduate, given that he or she is on financial aid, the following calculation must be performed:
6101 = 100
1879 = X
1879 x 100/6101 = X
187,900 / 6101 = X
30,798 = X
Therefore, the probability that a given student is a graduate, given that he or she is on financial aid, is 30.8%.

34% of the 6th graders and 50% of the 7th graders want to go to the water slides. What percentage of the 8th graders want to go to the water slides?
The percentage of the 8th graders to want to go to the water slides will be 70.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A fraction of 100 can be used to express the ratio.
The percentage of the 8th graders want to go to the water slides is found from;
[tex]\% (8 ^{th} grade)= 0.46-(0.5 \times 34 \%+0.3 \times 50\%_)\\\\ \% (8 ^{th} grade)=0.46-(0.17+0.15)\\\\ \% (8 ^{th} grade)=0.14\\\\ \% (8 ^{th} grade)= \frac{0.14}{0.20} \\\\ \% (8 ^{th} grade)=70\%[/tex]

Answer:
In Mathematics, the numbers can be classified into different types, namely real numbers, natural numbers, whole numbers, rational numbers, and so on. Decimal numbers are among them
Types of Decimal Numbers
Decimal Numbers may be of different kinds, namely
Recurring Decimal Numbers (Repeating or Non-Terminating Decimals)
Example-
3.125125 (Finite)
3.121212121212….. (Infinite)
Non-Recurring Decimal Numbers (Non Repeating or Terminating Decimals):
Example:
3.2376 (Finite)
3.137654….(Infinite)
Decimal Fraction- It represents the fraction whose denominator in powers of ten.
Example:
81.75 = 8175/100
32.425 = 32425/1000
Converting the Decimal Number into Decimal Fraction:
For the decimal point place “1” in the denominator and remove the decimal point.
“1” is followed by a number of zeros equal to the number of digits following the decimal point.
For Example:
8 1 . 7 5
↓ ↓ ↓
1 0 0
81.75 = 8175/100
8 represents the power of 101 that is the tenths position.
1 represents the power of 100 that is the units position.
7 represents the power of 10-1 that is the one-tenths position.
5 represents the power of 10-2 that is the one-hundredths position.
So that is how each digit is represented by a particular power of 10 in the decimal number.

A submarine begins 300 feet below sea level. It makes four moves of 30 feet each
toward the surface. How many more feet does the submarine need to move to reach
the surface?
Answer:
180 feet
Step-by-step explanation:
Starting number is 300. Four moves of 30 feet is 120 feet.
30x4 = 120
300-120 = 180
Answer:
180 feet.
Step-by-step explanation:
Remark
You need some formal way of expressing what is happening. You start at 300 feet below sea level, and make make 4 moves of 30 feet each. Where are you and how much further do you have to go to reach the surface?
Equation
Distance to go = distance in feet below sea level - number of moves * feet / move.
Givens.
original distance below sea level = 300 feet.
number of moves = 4
distance towards the surface for each move = 30 feet.
Distance to go. = ?
Solution
Distance to go = 300 - 4*30
Distance to go = 300 - 120
Distance to go = 180 feet
