Answer:
A = 2167.73 cm²
Step-by-step explanation:
Given that,
A trailer ramp is in the shape of a triangular prism.
the height of the ramp, h = 14 inches
The volume of the ramp, V = 4704 inches²
We need to find the area of the base of the trailer ramp.
The volume of the triangular prism is given by :
[tex]V=A\times h[/tex]
A is area of base and h is height
[tex]A=\dfrac{V}{h}\\\\A=\dfrac{4704}{14}\\\\A=336\ \text{inches}^2[/tex]
or
A = 2167.73 cm²
So, the area of the base of the ramp is 2167.73 cm².

Answer:
y=3x+10
Step-by-step explanation:
When two lines are parallel they are going to have the same slope which is 3x. The only thing we need to find is the y intercept based on the point they say the equation passes. to do this you take away the y intercept of the equation that we have and replace x with -2 and the subtract 4 to the side with the y.. now we have 4-y=-6 Then we solve for y and get y=10 which is the y intercept of the equation that is parallel to y=3x=1 and it passes (-2,4) Therefore the answer is y=3x+10

What is an expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Given expression as :
⇒ √-72k
And k= -2
To Evaluate the expression
Now Substitute the value of k= -2 in the expression
⇒ √- 72 × - 2
⇒ √ 144 [√ 144 = 12]
⇒ 12
Hence, the evaluated solution of √-72k for k = -2 is 12.

Answer:
The equation of line in the form of Ax + By = C is: [tex]\mathbf{4x+y=-17}[/tex]
Step-by-step explanation:
We need to find the equation of line, with the given slope passes through the given point.
Slope m = -4
Point: (-2,-9)
We need to find slope and y-intercept of the line.
The slope of line is given m = -4
Now, we need to find the y-intercept
Using the point (-2,-9) and slope m = -4, we can find y-intercept
The formula used will be: [tex]y=mx-b[/tex]
Putting values of: y= -9, x =-2 and m = -4
[tex]y=mx+b\\-9=-4(-2)+b\\-9=8+b\\b=-9-8\\b=-17[/tex]
So, y-intercept b = -17
Now, the equation of required line having slope m = -4 and y-intercept b = -17 is:
[tex]y=mx+b\\y=-4x-17[/tex]
Writing equation in required form i.e. of Ax + By = C
[tex]y=-4x-17\\4x+y=-17[/tex]
So, the equation of line in the form of Ax + By = C is: [tex]\mathbf{4x+y=-17}[/tex]

In 2006, there were 141 Asiatic lions in India . In 2011, there were 252 Asiatic lions in India Work out the percentage increase in the number of Asiatic lions in India from 2006 to 2011
Answer:
The percentage increase is 78.72%
Step-by-step explanation:
Here, we want to calculate a percentage increase
We proceed to use the mathematical relation as follows;
Percentage increase = (new value - old value)/old value * 100%
new value is value in 2011 = 252
old value is value in 2006 = 141
Substituting these values, we have;
(252-141)/141 * 100%
= 111/141 * 100%
= 78.72%

What theorem would you use to solve for x?
9514 1404 393
Answer:
Triangle Angle Sum
Step-by-step explanation:
Corresponding angles applies to parallel lines crossed by a transversal, or to angles in similar figure. The term has no meaning in this geometry.
Supplementary angles refers to a pair of angles that have a sum of 180°. Usually these are seen in quadrilaterals and figures involving parallel lines. The term has no meaning in this geometry.
The Pythagorean theorem relates side lengths in a right triangle. It has no utility in this geometry. Here we're concerned with angles, not sides.
__
The theorem useful for finding x is the Triangle Angle Sum theorem, which tells you the sum of angles in a triangle is 180°. That theorem lets you write a linear equation involving x, so that x can be found.
_____
(3x -2) +(x +8) +(2x +3) = 180
6x +9 = 180
x = 171/6 = 28.5°
The three angles are 36.5°, 60°, 83.5°.
The numbers are opposites.
The distance between the two numbers on the number line is 18.
9 and -9
Step-by-step explanation:
The distance between both are 18, and they are opposites because one is positive, and the other is negative.

Write 9 as a product of two primes.
Step-by-step explanation:
9 can be written as a product of 3 and 3
9=3×3 ( because 3 is a prime no. as it has two different factors ,i.e. 3 and 1)
Step-by-step explanation:
so we start using repeated division to find 9 as a product of primes.
First divide 9 by the smallest prime factor it has.
9/3=3
Next, divide the result (3) by the smallest prime factor it has.
3/3=1
Once you reach 1, which we just did, you have finished.
Now collect all the results you have.
3x3
There you go, 9=3x3, as a product of primes.
or 3^2, if you want to write it in index notation.
This works for any integer.

1) Graph this situation on
2) What does the graph tell you about the situation and how many solutions there are?
Answer:
ok so the graph tells you 24 seconds by 4 ounces
Step-by-step explanation:
The point where both lines meet is the point where they are both equal.
The point where both lines meet is (24,4)
Since the x-axis represents seconds the x-coordinate will represent the number of seconds it takes for them to be equal which is 24.
Since the y-axis represents ounces the y-coordinate will represent the number of ounces they have when they are equal which is 4.

A submarine travels 6.6 km due West from its base and then turns and travels due South for 3.9
km.
How far away is the submarine from its base?
Give your answer rounded to 1 DP.
Answer:
[tex]7.7[/tex] km
Step-by-step explanation:
The submarine's path from its base forms a right triangle when its final position is "connected" to the base. We know that the right triangle has legs of [tex]6.6[/tex] km and [tex]3.9[/tex] km, and we need to find the length of its hypotenuse. To do so, we can use the Pythagorean Theorem, which states that in a right triangle, [tex]a^{2}+b^{2} =c^{2}[/tex], where [tex]a[/tex] and [tex]b[/tex] are the lengths of the triangle's legs and [tex]c[/tex] is the length of the triangle's hypotenuse. In this case, we know what [tex]a[/tex] and [tex]b[/tex] are, and we need to solve for c, so after substituting the given values of [tex]a[/tex] and [tex]b[/tex] into [tex]a^{2}+b^{2} =c^{2}[/tex] to solve for c, we get:
[tex]a^{2}+b^{2} =c^{2}[/tex]
[tex]6.6^{2} +3.9^{2} =c^{2}[/tex] (Substitute [tex]a=6.6[/tex] and [tex]b=3.9[/tex] into the equation)
[tex]43.56+15.21=c^{2}[/tex] (Evaluate the squares on the LHS)
[tex]58.77=c^{2}[/tex] (Simplify the LHS)
[tex]c^{2}=58.77[/tex] (Symmetric Property of Equality)
[tex]\sqrt{c^{2} } =\sqrt{58.77}[/tex] (Take the square root of both sides of the equation)
[tex]c=7.7,c=-7.7[/tex] (Simplify)
[tex]c=-7.7[/tex] is an extraneous solution because you can't have negative distance, if that makes sense, so therefore, the submarine is approximately [tex]7.7[/tex] km away from its base. Hope this helps!
What is the distance between the points? Round to the nearest 10th if necessary
Answer:
5\sqrt(5) or about 11.2
Step-by-step explanation:

Using the pythagorean theorem, the distance is
\sqrt(25+100) = \sqrt(125) = 5\sqrt(5) or 11.2
An airplane is flying from New York City to Los Angeles. The distance it travels in miles, d, is related to the time in seconds, t, by the equation d=0.15t. How fast is it flying? Be sure to include the units.
Answer:
v=0.15 miles per second
Step-by-step explanation:
The distance it travels in miles, d, is related to the time in seconds, t, by the equation d=0.15t.
We need to find how fast is it flying.
Differentiate the given equation wrt t.
[tex]\dfrac{dd}{dt}=\dfrac{d}{dt}(0.15t)\\\\\because \dfrac{dd}{dt}=\text{velocity(v)}\\\\v=0.15[/tex]
It means the velocity of the airplane is 0.15 miles per second.
