Answer:

<h2>B)</h2><h3>You have $65 to spend on food while on a trip, but you need to save at least $9 for the train ride home. You plan to spend the rest on food that costs $8 each meal (including tax).</h3>

Step-by-step explanation:

Option B is the right answer because it's setting all operations properly, according to the given expression and the statement.

The given inequality, 65 − 8x ≥ 9, shows that the minimum is 9, which matches with the $9 minimum that the person need to save for the train, so the restriction is described properly.

Also, it says that the person have $65 in total, and he will spend $8 per meal, so, we don't know how many meals would be, that's <em>x</em>, and the spend means a subtract operation from the original $65, which is shown in the inequality. So, he will subtract each meal spend without going under $9. Therefore, the second statement fits perfectly with the given inequality.

Answer:

Theta =  120 degrees, 420 degrees, 480 degrees, 780 degrees, and 840 degrees

60 + 360 = 420 degrees,  

60 + 720 = 780 degrees,  

120 + 360 = 480 degrees,

120 + 720 = 840 degrees

Step-by-step explanation:

90  to 870 degrees for theta.

sin (theta) = root(3) /2

We see this comes from a 30-60-90 triangle.

theta is 60 degrees

but we want theta from 90 to 870 degrees.

120 degrees works too.

so we try to find all the co-terminal angles to 60 and 120 degrees that satisfy the conditions.

60 + 360 = 420 degrees,  

60 + 720 = 780 degrees,  

120 + 360 = 480 degrees,

120 + 720 = 840 degrees

If the radius and height of a cylinder are multiplied by 3, the lateral area of the cylinder is multiplied by
lutik1710 [3]
Answer:
The lateral area would be multiplied by 9

Explanation:
The lateral area of the cylinder can be calculated as follows:
lateral area = 2πrh
where:
r is the radius
h is the height

We are given that:
radius is multiplied by 3. This means that new radius is 3r
height is multiplied by 3. This means that new height is 3h

Substitute in the formula of the lateral area as follows:
lateral area = 2π(3r)(3h)
lateral area = 2*9*πrh
lateral area = 18πrh

Comparing the original lateral area with the new one, we would find that it is multiplied by 9

Hope this helps :)

Use the Distributive Property to find the price of 9 CDs that cost $13.99 each.
Andreas93 [3]
To use the distributive property, we "distribute" a value on the outside of a set of parentheses to all of the values on the inside of the parentheses. For example...

6(3 + 9) = 6*3 + 6*9

For your problem, you only have one value 13.99, but we can split it apart to make it a little easier to work with (like with mental math).  We can say that 13.99 is the same as 10 + 3.99.  Now we can take it and multiply by 9 with the distributive property...

9(10 + 3.99) =
9*10 + 9*3.99 =
90 + 35.91 =

$125.91

What was disney’s reaction to seeing pixar’s first proposal of toy story?
Alex_Xolod [135]

We're in the screening room of an exotic little San Francisco Bay area production company called Pixar Animation Studios, watching the dailies of a major work-in-progress, director John Lasseter presiding. And not to get too hyperbolic here, but we're witnessing history being made before our very eyes. You've heard of Debbie Does Dallas? Call this Disney Does Digital.

Two years ago, less than a half-dozen feature films employed the use of computer graphics; this year maybe a half-dozen won't use any sort of digital enhancements. If Hollywood has suddenly embraced the computer as a significant (and cost-effective) illusion-making tool, then Disney's Toy Story is arguably the most ambitious computer-generated undertaking yet.

hope this helps!

Explain why the negation of “Some students in my class use e-mail” is not “Some students in my class do not use e-mail”.
Olenka [21]

Answer with Step-by-step explanation:

Since we have given that

Some students in my class use e-mail.

It is a type of 'E' statements.

Its negation should be No students in my class use e-mail.

Because if we use "Some students in my class do not use e-mail”.

It also implies some students in my class still use e-mail.

But negation contains only opposite of given statement.

So, Some students in my class do not use e-mail” is not true.
