Answers

Answer 1

Answer:

C- 15 cars.

Step-by-step explanation:

To do this, you will need to set up an equation as follows:

8x+15=6x+45

Then you will subtract 6x from each side. Then you will have this:

2x+15=45

Then you will subtract 15 from each side, and then you will have:

2x=30

Then you will divide each side by 2 and you will get 15. Hope this helped!

If JK = 7 and JL = 12, what is JM?

Answers

Final answer:

Without additional context or details about how JK, JL, and JM are related, it's impossible to accurately calculate or deduce the value of JM. Further clarification or more information about the scenario or the mathematical or geometric principles involved is needed for a precise answer.

Explanation:

The question provided does not seem to present enough context or connection to standard mathematical operations or geometric principles that would enable a straightforward calculation or deduction of the value of JM. Without additional information about the relationship between JK, JL, and JM (such as whether they are sides of a triangle, or represent values in a given mathematical formula), or without a clear mathematical or geometric context, it's impossible to accurately determine the value of JM.

Generally, in mathematics, when calculating distances or values based on given lengths, one needs to apply specific formulas or theorems (such as the Pythagorean theorem in the context of right-angled triangles, or vector addition in the context of physics problems). Unfortunately, the given data lacks the necessary context to apply such principles.

For a precise and accurate answer, I recommend clarifying the problem's context or providing more details about the scenario in which JK, JL, and JM are related.

-Final answer:

To find JM in a triangle with known side lengths JK = 7 and JL = 12, we use the Triangle Inequality Theorem to determine that JM must be less than 19.

Explanation:

To find JM, we can use the fact that in a triangle, the sum of the lengths of any two sides must be greater than the length of the third side (Triangle Inequality Theorem).

JK + JL > JM

7 + 12 > JM

19 > JM

Therefore, JM must be less than 19 but more than the absolute difference of JK and JL, so JM < 19.

Line v has a slope of -5/2
Line w is parallel to line v. What is the slope of line w?
Simplify your answer and write it as a proper fraction, improper fraction, or integer,

Answers

Answer:

-5/2

Step-by-step explanation:

Since they are both parallel they have the same rate of change. this means they have the same slope

Final answer:

Since line w is parallel to line v, which has a slope of -5/2, the slope of line w is also -5/2.

Explanation:

When two lines are parallel, they have the same slope. In this case, the slope of line w will be the same as the slope of line v.

Therefore, the slope of line w is -5/2.

The question asks about the slope of two parallel lines. By definition, parallel lines have the same slope. Given that line v has a slope of -5/2, and line w is parallel to line v, the slope of line w must also be -5/2. Therefore, line w, being parallel to line v, has a slope of -5/2.

Step-by-step explanation:

Answer:

x> 6 twice

Step-by-step explanation:

x^2+36>12x

x² + 36 > 12x

Collect like terms

x² - 12x + 36 > 0

Solve quadratically using factorisation method by finding two factors of 36 that when added gives -12, the coefficient of x.

Factors = -6 and -6 which both add up to -12

Rewrite equation

x² - 6x - 6x +36> 0

Factorise by taking out the common factor

x ( x - 6) -6( x - 6) > 0

(x -6)(x - 6) > 0

x - 6 > 0 or x -6 > 0

Add 6 to both sides

x -6+6> 0+6 or x-6+6>0+6

x > 6  or x> 6

x> 6 twice

9. Rama is using a hand glider to fly directly from the top of one cliff onto another cliff below. The glider is guided by a cable. The cliffs are 740 feet apart and the first cliff is 280 feet taller than the second cliff. How long is the cable between the cliffs?

Answers

Answer:

791.2 ft

Step-by-step explanation:

The cable is inclined and this acts as the hypotenuse. Since the other two sides are given.

[tex]H=\sqrt {x^{2}+y^{2}}[/tex]

where x and y represent the distance between two cliffs apart and difference in heights. Substituting 740 for x and 280 for y then

[tex]H=\sqrt {740^{2}+280^{2}}=791.20161779409930627669981858168023442712 ft\approx 791.2 ft[/tex]

Answer:

791.2 ft to the nearest tenth.

Step-by-step explanation:

From the diagram,we assume :

AD to be the height of the first cliff

BC to be the height of the second cliff

DC to be the length of the cable between the top of the two cliff.

AD=740 ft.

DE= 280 ft.

Using Pythagorean Theorem, we obtain.;

[tex] {DE}^{2}+ {CE}^{2} = {DC}^{2} [/tex]

By substitution we obtain

[tex] {280}^{2} + {740}^{2} = [/tex]

[tex] \implies78400 + 547600 = {DC}^{2} [/tex]

[tex]\implies626000= {DC}^{2} [/tex]

Taking positive square root.

[tex]\implies DC = \sqrt{626000} [/tex]

[tex] \implies DC =791.202 ft[/tex]

h(x)=square root of x-10
what is the domain of h?

Answers

h(x)= square root of x-10
Domain: x >= 10
Final answer:

The domain of the function h(x) = √(x-10) is all real numbers x that are greater than or equal to 10, because we cannot take the square root of a negative number under the real number system.

Explanation:

In mathematics, the domain of a function is the set of all the possible input values (usually denoted as x) that would lead to a real and defined output. As for the function h(x)=√(x-10), we have a square root operation involved. We know that under the real number system, we cannot take the square root of a negative number.

Hence, for the function h(x)=√(x-10) to be real and defined, (x-10) must be greater than or equal to 0. That is, x-10 ≥ 0. Solving for x, we get x ≥ 10.

Therefore, the domain of the function h(x) = √(x-10) is x≥10. That is, h(x) is defined for all real numbers x that are greater than or equal to 10.

What is the equation of a line that passes through the points (-3, 4) and (2, 8)?

Answers

Answer:

y= 4/5x +2/5

Step-by-step explanation:

When finding slope, use the format y-y1/x-x1. Plug in your coordinates to get this: 8-4/2--3. 8-4 equals 4, and 2--3 equals 5. So, your slope would be 4/5. Next, make your equation like this: y=4/5x+b. Next, plug in one of your ordered pairs into the equation. It doesn't matter which one you use. I'm going to use the second pair, so it would look like this: 8=4/5(2)+b. Multiply 4/5 by 2 to get 8/5. This is what you should have: 2=8/5+b. Subtract 8/5 from both sides to get your y-intercept of 2/5. Go back to your original equation and plug in 2/5 to b. This is your final equation: y= 4/5x +2/5. Hope this helped!

The frequency of red light is 4 x 10¹⁴ Hz. The correct answer is option D.

What is the Scientific Notation?

Scientific Notation is a way of writing down in the easy form of very large or very small numbers.

The given that when the frequency of an electromagnetic wave is 400,000,000,000,000 Hz, it results in red light.

The choices given are in scientific notation form, where the coefficient is multiplied by 10 raised to a certain power of 10.

To convert 400,000,000,000,000 Hz into scientific notation, we need to move the decimal point 14 places to the left to obtain a coefficient between 1 and 10.

This gives us 4.0 as the coefficient, and since we moved the decimal point 14 places to the left, the power of 10 is -14.

Therefore, the frequency of red light is 4 x 10¹⁴ Hz.

Which answer is correct?

Answers

Well, since the graph starts at (0,50), making our y-intercept 50, we can knock off D as an option.

The next step is to find the slope. To do this, find two points and subtract the y values over the x values. (Just make sure that whichever y value you start with - start with the same x value).

So we have >>> (50, 200) and (0,50) from earlier.

200 - 50 / 50 - 0 = 150/50 or 3/1, or 3.

This makes the correct answer A since the equation is represented as y = mx + b, where m is the slope and m has a value of 3.

Four CDs and 4 DVDs cost $164. The cost of the 4 CDs is half the cost of the
4 DVDs. What is the cost of each CD?

Answers

Answer:

$13.67

Step-by-step explanation:

Let's say that CD= c and DVDs= d. Four CDs and 4 DVDs cost $164, so the equation will be:

i.  4c + 4d= 164

The cost of the 4 CDs is half the cost of the  4 DVDs, to put into an equation it will be:

ii.   4c= 0.5(4d)

     4c= 2d

     d= 2c

Then we can substitute the second equation (ii) into the first equation (i). The calculation will be:

4c + 4d= 164

4c + 4(2c)= 164

4c+ 8c= 164

12c= 164

c=13.67

The cost for each CD is $13.67
