Answer:

B) 0.82

E) 0.76

Step-by-step explanation:

I'll use B, 0.82, as an example.

When you round a number, in this case 0.82, you first find which place you're rounding to. In this problem, we're rounding to the tenth place, or the "8" in 0.82.

Next, you look one digit to the right of the tenth place (or whatever place you're using in your problem). In this problem, that is the hundredth place, or the "2" in 0.82.

Then, you're going to decide whether your digit (in this case, the 2) is closer to 10 or 0. If the digit is 5, assume its closest to 10.

If your digit is closer to 10, then you're going to round up, by removing the digit to the right of the place you're rounding to, and increase the digit in the place you're rounding to by 1.

If your digit is closer to 0, then simply remove the digit to the right.

Using those steps, 0.82 rounded to the nearest tenth is 0.8.

You can use a number line if you're more of a visual learner, hope this helps!

Answer: y=7.3

Y=-7/16

Step-by-step explanation:

function: f(0.6) = 2.5x + 5.8

solution: 7.3

2.5(0.6) = 1.5

1.5 + 5.8 = 7.3

function: f(1/4) = 3/4x - 5/8

solution: -7/16

3/4(1/4) = 3/16

3/16 - 5/8 = -7/16

Answer:

y = 2x - 18

Step-by-step explanation:

There are lots of different methods to do these types of questions, but this is the way i like to do it.

Coordinate (x1, y1) : (4, -10) and Gradient (m): 2

Start with this generic equation:

y- y1 = m(x-x1)

Substitute in the values they have given you:

y - (-10) = 2(x-4)

This becomes:

y + 10 = 2x - 8

Keep solving by moving the 10 over to the other side:

y = 2x -8-10

y = 2x - 18

An easy way to double check:

1) the coefficient of x is the slope. We got 2x, and the slope is 2, so that's correct.

2) Substitute x=4 into the equation, and we get -10, which is the exact coordinate that they gave us. This is also right.

Answer:

To find the correct selling price, we need to first find the cost of the item plus the markup. We can do this by multiplying the cost of the item by the markup percentage: $6 * 67% = $4.02. However, since the question asks us to round to the nearest dollar, we can round this number down to $4.

Therefore, the correct selling price is $4.

The manager's likely error was that they set the selling price at the cost (option C).

Step-by-step explanation:

The correct selling price is $10 and the manager set the selling price at the markup so option (A) is correct.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Cost of item = $6

Markup = 67%

67% of $6 ⇒ 0.67 x 6 = $4.02

Add the markup in the cost = $6 + $4.02 = $10.02

Round to nearest dollars = $10.2 ≈ $10.

The manager put $4 which is a markup instant of the selling price of $10.

Hence "The correct selling price is $10 and the manager set the selling price at the markup".

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Answer:

\(A=\frac{ab}{2}\) or \(A = a *\sqrt{c^2-a^2} /2\)

Step-by-step explanation:

Depending on the values you take depends on the equation you would use to solve for the area of a right triangle(the first answer accounts for measuring both arms(the sides connected to the 90 degree angle(a and b)), where as the second answer accounts for using the hypotenuse and one of the arms). That means that a 90 degree angle is involved, or as illustrated here, the square in the bottom right corner. If this were a non-right angle triangle, a different formula utilizing the height of the triangle would be used instead.

\(A = \frac{h_{b}+b}{2}\)

Since the right angle exists, a height is already given using one of the arms of the triangle in its place. We can also confirm it is a triangle by adding up all degrees of the triangle, in which it would equal 180 degrees confirming it is indeed a triangle as well.

By using trigonometric relations we will see that the area is:

How to find the area of one triangular section?

Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.

Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).

h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:

tan(60°) = x/h

x = tan(60°)*h

Then our two catheti are h and tan(60°)*h.

This means that the area will be:

Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).

Answer:

168°

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle, which is k, in this case.

m∠J = 78 and m∠L = 90° so the measure of exterior angle to ∠K:

78 + 90 = 168°

   Submarine must descend by 12 feet in the fifth minute.

From the table given in picture,

Let the distance descended by submarine in 5th minute = x feet

Average distance descended by the submarine = \(\frac{\text{Total distance distended}}{\text{Duration or time}}\)

                                                                                = \(\frac{8+10+8+12+x}{5}\)

                                                                                = \(\frac{38+x}{5}\) feet per minute

Statement given in the question → "Submarine must descend at an average rate of at least 10 feet per minute"

So the inequality for the statement will be,

\(\frac{38+x}{5}\geq 10\)

38 + x ≥ 50

x ≥ 50 - 38

x ≥ 12

    Therefore, submarine must descend 12 feet in the 5th minute.
