Answer: X = 2.4

Step-by-step explanation:

The first step should be to isolate x or get x alone. This means we should get rid of the divided by 2 on the left by multiplying both sides by 2. This would get us to 2 * X/2 = 1.2 * 2. The multiplying X/2 would simplify to just X, and the 1.2 * 2 = 2.4. Therefore the final equation would become X = 2.4.

To check, you would plug in 2.4 into where X is in X/2 = 1.2. Since 2.4/2 = 1.2, we know that X = 1.2 from checking.

x = 2.4

You want to get x by itself, so you need to get rid of the division on the left side of the equals sign. The way to undo division is to multiply. So, multiply both sides of the equation by 2. This gives you x = 2.4, so now you have your answer.

Now, since the problem wants us to check our answer, we just put 2.4 back into the equation as x. This gives us 2.4 / 2 = 1.2. Now, we just simplify to see if the equation is true. If it is true, the answer is correct. 2.4 divided by 2 is 1.2, so 1.2 = 1.2, which means our answer is correct.

We are to find the time it takes a flare to reach 36 feet. After rearranging the given equation and solving for the time 't', we find that the time is approximately 0.867 seconds. However, this value is not listed in the provided options. The closest given answer choice is 0.75 seconds.

The given equation for the height of a flare is: h = -16 + 60t where 'h' stands for height and 't' stands for time. First, we need to solve the equation for 't', as we're looking to find the time it takes for the flare to reach 36 feet.

So, the equation becomes: 36 = -16 + 60t.

We add 16 to both sides of the equation to isolate the term with 't': 52 = 60t.

Then, we divide both sides of the equation by 60. We now have: t = 52/60. Solving it returns t = 0.867 seconds.

However, this value is not listed in the given answer choices. Among the choices, the closest is 0.75 seconds, or option A. Hence, 0.75 seconds is likely the approximate value considered correct for this problem.

Step-by-step explanation

type 2.08^5 and then times it to 14.08

Hello there! The answer is C.

So the equation is y = 14.08 ⋅ 2.08^x, where x stands for the number of years. You are finding the number of fish after five years, so place five in for x and solve.

y = 14.08 ⋅ 2.08^5 - Start by finding 2.08 to the 5th power. (I rounded off some decimal points since it was too long.)

y = 14.08 x 38.9329 - Next: multiply your two numbers.

y = 548.175232, or C since it is the closest whole number.

The side across angle 18 is the opposite side. The perpendicular angle that touches the same line is adjacent. To figure out the length of JL, we need to use the measurement 34.6 mm (hypotenuse). So in this equation we will use hypotenuse to find opposite. Hypotenuse and opposite result in Sin on the calculator. So on the calculator, you would find the Sin of 18 and then multiply that number by 34.6. The answer would then be 10.7 (rounded).

Answer: 10.7 mm (rounded)

Answer:

JL ≈ 10.7 mm

Step-by-step explanation:

Using the sine ratio in the right triangle

sin18° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{JL}{34.6}[/tex]

Multiply both sides by 34.6

34.6 × sin18° = JL, hence

JL ≈ 10.7 ( to 1 dec. place )

The only trinomial among the four expressions is x^6 −x+ √6 .

A trinomial is an algebraic expression with three terms, each containing a power of the variable raised to a non-negative integer and multiplied by a coefficient.

Let's analyze each expression:

x^3 + x^2 - √x: This has three terms (x^3, x^2, and -√x), but √x contains a fractional exponent, which is not allowed in a polynomial (and therefore, a trinomial). So, it's not a trinomial.

2x^3 - x^2: This has two terms (2x^3 and -x^2), not three. Therefore, it's not a trinomial.

4x^3 + x^2 - 1/x: This has three terms (4x^3, x^2, and -1/x), but 1/x is equivalent to x^-1, which is a negative exponent.

Similarly to option 1, this violates the non-negative integer exponent requirement for polynomials. So, it's not a trinomial.

x^6 - x + √6: This has three terms (x^6, -x, and √6). Note that √6 does not contain a variable and can be considered a constant, satisfying the polynomial and trinomial requirements. Therefore, this is a trinomial.

In, the only trinomial among the given options is: 4. x^6 - x + √6 .

The trinomial expression is C. [tex]\(4x^3 + x^2 - \frac{1}{x}\).[/tex]

A trinomial is an algebraic expression consisting of three terms. Let's examine each option:

a. [tex]\(x^3 + x^2 - \sqrt{x}\)[/tex] - This is a polynomial expression, but it only has two terms, so it's not a trinomial.

b. [tex]\(2x^3 - x^2\)[/tex] - This expression has two terms, so it's not a trinomial.

c. [tex]\(4x^3 + x^2 - \frac{1}{x}\)[/tex] - This expression has three terms, so it is a trinomial.

d. [tex]\(x^6 - x + \sqrt{6}\)[/tex] - This expression also has only three terms, so it is a trinomial.

Step-by-step explanation:

In 1862, president Abraham Lincoln decided to relieve General George McClellan of his command after the Battle of Antietam. The reason is McClellan was unable to concentrate his forces effectively, so the Confederate army shifted his defenders to block each of three Union thrusts. Besides, he was unable to employ his large reserved forces to ensure success.

Answer:

Step-by-step explanation:

The cosine of angle Ф is √(1 - sin²Ф), which is positive if our angle 81 degrees is in Quadrant I.

sin 81° = 0.9877, so (sin 81°)² = 0.9755, and

cos 81° = 1 - 0.9755 = 0.0245

To find the cosine of 81 degrees in terms of sine, we use the identity cos(Ф) = sin(90° - Ф), giving us cos(81°) = sin(9°).

To find the cosine of 81 degrees in terms of sine, we use the trigonometric identity that relates sine and cosine for complementary angles. The cosine of 81 degrees is the same as the sine of 9 degrees, because 81 and 9 add up to 90 degrees. The trigonometric identity is cos(Ф) = sin(90° - Ф).

Using this identity:

cos(81°) = sin(90° - 81°)

= sin(9°).

Therefore, the cosine of 81 degrees is equal to the sine of 9 degrees.

Answer:x=8,y=1

Step-by-step explanation:

2x+4y=20

So, 4y=20-2x

So,2y=10-x

Now we can use this information to use in the second equation

3x+2y=26

3x+(10-x)=26

2x+10=26

2x=16

x=8

Now that we know that x=8, then we can solve for y.

2x+4y=20

2(8) +4y=20

16+4y=20

4y=4

y=1

Here is the process of how I did it:

Step 1:     Make this equation : 2x+4y = 20 equal x by isolating x and bring everything else on the right side of the equation

2x + (4y-4y) = 20 - 4y

2x = 20 - 4y

[tex]\frac{2x}{2}  = \frac{20 - 4y}{2}[/tex]

x = 10 - 2y

Step 2: In the other equation given (3x+2y=26​) every time you see an x replace it with the equation solved above (x = 10 - 2y). This will help you find the y

3x+2y=26​ ---> 3(10 - 2y)+2y=26​

10(3) - 2y(3) + 2y = 26

30 - 6y + 2y = 26

(30-30) - 4y = (26 - 30)

[tex]\frac{-4y}{-4} =\frac{-4}{-4}[/tex]

y = 1

Step 3: In the equation you found in step 1 (x = 10 - 2y) plug 1 into all the y's so you can find x

x = 10 - 2y ---> x = 10 - 2(1)

x = 10 - 2

x = 8

Hope this helped!

Answer: x=54

Step-by-step explanation:

When you add up all of the sides that have to equal 360 degrees. so, the first thing that you would do is 72+72. You would do that because there are actually 2 72 in the rhombus. That equals 144. then you would do 360-144. That equals 216. Then you would do 216/4. You would do 216/4 because there are actually 4 x in the rhombus. After you divide 216/4 it equals 54. to check your work you would do 54+54+54+54+72+72. That equals 360. So the value of x = 54 degrees.

can you just measure r and times that by 72

For this case we must raise an inequality.

We have "d" dollars initially and they are spent 12. Then:

[tex]d-12\geq 51[/tex]

Resolving:

[tex]d\geq 51 + 12\\d\geq 63[/tex]

Answer:

[tex]d-12\geq 51\\d\geq 63[/tex]

Answer:

If the number of miles is 6

Step-by-step explanation:

Since they vary with different rates ($/mile in our case), such equality can only be true for a specific amount of miles.  Less miles and the left part ($2.50...) would be higher, more miles and the right part ($1.00...) would be higher because it grows faster.

So, that's the number of miles for which the equation is true?

2.50 + 0.50m = 1.00 + 0.75m

Let's regroup similar terms:

1.50 = 0.25m

the isolate m

m = 6

So, if the ride covers 6 miles, the equation is true:

2.5 + 0.5 (6) = 1.00 + 0.75 (6)

2.5 + 3 = 1 + 4.50

5.5 = 5.5

Answer:

One cab charges an initial fee of $2.50 and then $0.50 for every mile. The other cab company charges an initial fee of $1.00 and then $0.75 for every mile.
