Answer:

15 students

Step-by-step explanation:

5 DIVIDED by 8

You then multiply by 24

The method i just explained is known as cross multiplication

By multiplying the total number of students (24) by the fraction (5/8), we find that 15 students earned an A on their geometric unit assessment in Mr. Bonogofsky's class.

In Mr. Bonogofsky's math class, there are 24 students. If 5/8 of the students earned an A on the geometric unit assessment, we would need to multiply the total number of students by 5/8 to determine how many got an A.

Here's how to do it: 5/8 * 24 = 15

So, 15 students in Mr. Bonogofsky's class earned an A on the geometric unit assessment.

Answer:

9

Step-by-step explanation:

its difficult to explain but I found that there is a 10.3%Tax so 10.3% of 93 is 9

The sales tax on the second item, which cost $93 before tax, would be approximately $8.99 based on the tax rate of the first item.

To determine the amount of sales tax on the second item, we first need to understand the rate of sales tax applied to the first item. The sales tax on the first item was $21 on a pre-tax cost of $217. So, the tax rate would be 21 divided by 217, which is approximately 0.0967, or 9.67%.

If we apply this tax rate to the second item, which costs $93 before tax, we get 93 times 0.0967, or $8.99. Therefore, the amount of sales tax on the second item would be approximately $8.99.

Answer:

Associative  

Step-by-step explanation:

The associative property of addition states that you can add numbers however they are grouped inside parentheses.  

It doesn't matter where you put the parentheses. You will always get the same answer.

For example,

[tex]\begin{array}{rcl}(5 + 3) + 7 & = & 5 + (3 + 7)\\8 + 7& = & 5 + 10\\15 & = & 15\\\end{array}[/tex]

Answer:

Step-by-step explanation:

Lines are considered to be perpendicular if the angle between at the point they intersect is 90°, or a right angle.

If you have the equations of two lines, you can determine if they are perpendicular by looking at their slope. For the slope-intercept form of a line,

[tex]y = mx + b[/tex]

[tex]m[/tex] is the slope of the line.

Two lines are considered perpendicular, if the slope of one line is [tex]m[/tex], and the slope of the other line is [tex]\frac{1}{-m}[/tex].

For example, if a line had a slope of 4, say [tex]y = 4x + 2[/tex], then a line that would be perpendicular to this line would have a slope of [tex]\frac{-1}{4}[/tex], say [tex]y = \frac{-1}{4} + 7[/tex].

Answer:

(-1, -1.5)

Step-by-step explanation:

A coordinate is a point (a single place) on a graph. Coordinates can be recorded as (#, #).

The first number is the one on the x-axis (left/right) and the second number is the one on the y-axis (up/down). (x, y) The middle point, where the x-axis and y-axis meet is called the origin, and is at (0,0).

The point that marks the campground is at -1 on the x-axis and -1.5 on the y axis.

Because the y-axis has two lines for every whole number, the line in between is the halfway mark and counts as a 0.5 increment.

Answer:

y - 2 = [tex]\frac{1}{3}[/tex](x - 3)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = [tex]\frac{1}{3}[/tex] and (a, b) = (3, 2), thus

y - 2 = [tex]\frac{1}{3}[/tex](x - 3) ← in point- slope form

We want to find the equation of a line in the point-slope form, such that we know the slope and a point on the line.

The line will be: y - 2 = (1/3)*(x - 3)

Let's see how to find that line:

We know that our line has a slope equal to 1/3, and that it passes through the point (3, 2).

First, a general line in the point-slope form is:

y - y₁ = a*(x - x₁)

Where a is the slope and (x₁, y₁) is the point on the line.

Then, by using that general form and the given information, we can see that our line is:

y - 2 = (1/3)*(x - 3)

7000 - 24x = y(the amount he can sell the car for)

Step-by-step explanation:

Answer:

7000 - 24x

Step-by-step explanation:

Johnny bought a car for $7000  about 2 years ago.

He wants to sell his car now.

The monthly depreciation amount = $x

2 years = 2 x 12 = 24 months.

The amount of depreciation for 2 years = 24x.

Step-by-step explanation:

6 is divisible by 2 and 3 (6 = 2 · 3).

257 is not divisible by 2 and 3 (257 is a prime number).

Therefore 257 is't divisible by 6.

Final answer:

257 is not divisible by 6 because it is not even.

A number must be even and the sum of its digits divisible by 3 to be divisible by 6.

Explanation:

To determine if 257 is divisible by 6, we need to check if it satisfies the criteria for divisibility by 6.

A number is divisible by 6 if it is divisible by both 2 and 3.

Examining 257, we see that it ends with a 7, which is not an even number.

So it does not meet the criterion for divisibility by 2.

Therefore, 257 is not divisible by 6.

-16/8 or -16÷8 equals -2 which is a whole number

an integer is a whole number that is positive ,negative or zero

Examples of integers: 1, 2, -5, -18, 20

Not Integers: 0.2, 9.15, 2/3

Final answer:

The division of -16 by 8 results in -2, which is an integer because it has no decimal component. Therefore, -16/8 is an integer.

Explanation:

The question is whether -16/8 is an integer. To determine this, we simply perform the division: -16 divided by 8 equals -2. Since -2 has no decimal component, it is indeed an integer. Integers are whole numbers that can be positive, negative, or zero, but do not include fractions or decimals. Examples of integers include -8, -6, -2, 0, 4, and 12. In this case, -16/8 simplifies precisely to -2, which is an integer.

Answer:

Step-by-step explanation:

Law of sines is:

(sin A) / a = (sin B) / b = (sin C) / c

Law of cosines is:

c² = a² + b² − 2ab cos C

Note that a, b, and c are interchangeable, so long as the angle in the cosine corresponds to the side on the left of the equation (for example, angle C is opposite of side c).

Also, angles of a triangle add up to 180° or π.

(i) sin(B−C) / sin(B+C)

Since A+B+C = π, B+C = π−A:

sin(B−C) / sin(π−A)

Using angle shift property:

sin(B−C) / sin A

Using angle sum/difference identity:

(sin B cos C − cos B sin C) / sin A

Distribute:

(sin B cos C) / sin A − (cos B sin C) / sin A

From law of sines, sin B / sin A = b / a, and sin C / sin A = c / a.

(b/a) cos C − (c/a) cos B

From law of cosines:

c² = a² + b² − 2ab cos C

(c/a)² = 1 + (b/a)² − 2(b/a) cos C

2(b/a) cos C = 1 + (b/a)² − (c/a)²

(b/a) cos C = ½ + ½ (b/a)² − ½ (c/a)²

Similarly:

b² = a² + c² − 2ac cos B

(b/a)² = 1 + (c/a)² − 2(c/a) cos B

2(c/a) cos B = 1 + (c/a)² − (b/a)²

(c/a) cos B = ½ + ½ (c/a)² − ½ (b/a)²

Substituting:

[ ½ + ½ (b/a)² − ½ (c/a)² ] − [ ½ + ½ (c/a)² − ½ (b/a)² ]

½ + ½ (b/a)² − ½ (c/a)² − ½ − ½ (c/a)² + ½ (b/a)²

(b/a)² − (c/a)²

(b² − c²) / a²

(ii) a (cos B + cos C)

a cos B + a cos C

From law of cosines, we know:

b² = a² + c² − 2ac cos B

2ac cos B = a² + c² − b²

a cos B = 1/(2c) (a² + c² − b²)

Similarly:

c² = a² + b² − 2ab cos C

2ab cos C = a² + b² − c²

a cos C = 1/(2b) (a² + b² − c²)

Substituting:

1/(2c) (a² + c² − b²) + 1/(2b) (a² + b² − c²)

Common denominator:

1/(2bc) (a²b + bc² − b³) + 1/(2bc) (a²c + b²c − c³)

1/(2bc) (a²b + bc² − b³ + a²c + b²c − c³)

Rearrange:

1/(2bc) [a²b + a²c + bc² + b²c − (b³ + c³)]

Factor (use sum of cubes):

1/(2bc) [a² (b + c) + bc (b + c) − (b + c)(b² − bc + c²)]

(b + c)/(2bc) [a² + bc − (b² − bc + c²)]

(b + c)/(2bc) (a² + bc − b² + bc − c²)

(b + c)/(2bc) (2bc + a² − b² − c²)

Distribute:

(b + c)/(2bc) (2bc) + (b + c)/(2bc) (a² − b² − c²)

(b + c) + (b + c)/(2bc) (a² − b² − c²)

From law of cosines, we know:

a² = b² + c² − 2bc cos A

2bc cos A = b² + c² − a²

cos A = (b² + c² − a²) / (2bc)

-cos A = (a² − b² − c²) / (2bc)

Substituting:

(b + c) + (b + c)(-cos A)

(b + c)(1 − cos A)

From half angle formula, we can rewrite this as:

2(b + c) sin²(A/2)

(iii) (b + c) cos A + (a + c) cos B + (a + b) cos C

From law of cosines, we know:

cos A = (b² + c² − a²) / (2bc)

cos B = (a² + c² − b²) / (2ac)

cos C = (a² + b² − c²) / (2ab)

Substituting:

(b + c) (b² + c² − a²) / (2bc) + (a + c) (a² + c² − b²) / (2ac) + (a + b) (a² + b² − c²) / (2ab)

Common denominator:

(ab + ac) (b² + c² − a²) / (2abc) + (ab + bc) (a² + c² − b²) / (2abc) + (ac + bc) (a² + b² − c²) / (2abc)

[(ab + ac) (b² + c² − a²) + (ab + bc) (a² + c² − b²) + (ac + bc) (a² + b² − c²)] / (2abc)

We have to distribute, which is messy.  To keep things neat, let's do this one at a time.  First, let's look at the a² terms.

-a² (ab + ac) + a² (ab + bc) + a² (ac + bc)

a² (-ab − ac + ab + bc + ac + bc)

2a²bc

Repeating for the b² terms:

b² (ab + ac) − b² (ab + bc) + b² (ac + bc)

b² (ab + ac − ab − bc + ac + bc)

2ab²c

And the c² terms:

c² (ab + ac) + c² (ab + bc) − c² (ac + bc)

c² (ab + ac + ab + bc − ac − bc)

2abc²

Substituting:

(2a²bc + 2ab²c + 2abc²) / (2abc)

2abc (a + b + c) / (2abc)

a + b + c
