Hi there!

The following answers are:

14: to determine whether or not the slopes are perpendicular to one another is the negative reciprocal. In other words, if the first slope is m, the perpendicular slope is -1/m

to determine whether or not the slopes are parallel, the slopes are the same. In other words, if the first slope is m, then the parallel slope is m

So in other words: 1. perpendicular 2. neither 3. perpendicular 4. parallel

15: There are four types of rigid motions that we will consider: translation , rotation, reflection, and glide reflection.

Answer:

Since there is one peak, we can call this unimodal. As the numbers do not exactly match up (for example, 20-39 is 21 and 60-79 is 23), this is not symmetric, but it is approximately symmetric as the numbers are similar

40-50 of number of texts has more number of middle school students 33 and from 0-19 has less number of middle school students.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

A histogram is a bar graph-like representation of data that buckets a range of classes into columns along the horizontal x-axis.

The vertical axis  was represented by number of school students.

The horizontal axis is represented by number of texts.

The As the numbers do not exactly match up (for example, 20-39 is 21 and 60-79 is 23), this is not symmetric, but it is approximately symmetric as the numbers are similar

At 40-50 of number of texts has more number of middle school students 33 and from 0-19 has less number of middle school students

Answer:

Beki's jersey number is 34. She last 12 minutes

Nick's jersey number is 20. He last 10 minutes

Carmen's jersey number is 2. She last 14 minutes

Joey's jersey number is 13. He last 11 minutes

Step-by-step explanation:

• The sum of the digits on Beki's jersey number is 7. Therefore, Beki's number is necessarily 34 (3+4 = 7)

• Nick's jersey number is 18 greater than Carmen's. Therefore, Nick's jersey number is 20 and Carmen's jersey number is 2 (2 + 18 = 20). If Carmen's jersey number was 13, 13+18 = 31 which is not included in the options. If it was 20, 20+18 = 38 is not included either.

• From previous items, Joey's jersey number is 13

• The runner with the lowest jersey number also ran the slowest time. Therefore, Carmen last 14 minutes

• Nick finished exactly 2 minutes faster than Beki. Therefore, Nick's time is 10 minutes and Beki's time is 12 minutes, because from the remaining options (10, 11 and 12) this is the only combination 2 minutes apart.

• From previous items, Joey's time is 11 minutes

Step-by-step explanation: To get the answer to this word problem all we have to do is multiply height * thickness * width.

First, let's turn 6 [tex]\frac{1}{2}[/tex] into a decimal...

1 ÷ 2 = 0.5

6 [tex]\frac{1}{2}[/tex] = 6.5

6.5 * 3 * 13 = 253.5

Now, we have to multiply it by the remaining amount of stones...

253.5 * 17 = 4309.5

V ≈ 4309.5

Answer:

170°

Step-by-step explanation:

Let a be the distance from Los Angeles to Chicago = 1744 miles, b be the distance from Chicago to New York = 714 miles and c be the distance from New York to Los Angeles = 2451 miles.

A is the angle opposite to side a, B is the angle opposite to side b and C is the angle opposite to side c.

Therefore the angle at Chicago is  C.

From cosine rule:

c² = a² + b² - 2ab × cos (C)

2ab × cos (C) = a² + b² - c²

cos (C) = (a² + b² - c²) / 2ab

Substituting:

cos (C) = (1744² + 714² - 2451²) / 2×1744×741

cos (C) = -0.986

C = cos⁻¹ (- 0.986) = 170°

The difference between the two given fractions is [tex]\frac{x^2 + 4x - 1}{x^2 + 2x}[/tex].

The given parameters:

[tex]\frac{x + 5}{x + 2} - \frac{x+ 1}{x^2 + 2x}[/tex]

The difference between the two fractions is calculated as follows;

[tex]\frac{x + 5}{x + 2} - \frac{x+ 1}{x^2 + 2x}\\\\= \frac{x + 5}{x + 2} - \frac{x+ 1}{x(x + 2)}\\\\[/tex]

The lowest common multiple (L.C.M) of the two denominators = x(x + 2)

[tex]= \frac{x(x + 5) - (x + 1)}{x(x + 2)} \\\\= \frac{x^2 + 5x - x - 1}{x^2 + 2x} \\\\= \frac{x^2 + 4x - 1}{x^2 + 2x}[/tex]

Thus, the difference between the two given fractions is [tex]\frac{x^2 + 4x - 1}{x^2 + 2x}[/tex].

Answer:

500

Step-by-step explanation:

here

principal(p)=2500

rate (R)=5%

Time (T)=4 years

now,

Intrest (I)=(P×T×R)/100

(2500×5×4)/100

=Rs 500

After 4 years the investment of $2500 will be $3051.02.

Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.

Compound interest is calculated by multiplying the initial principal amount (P) by one plus the annual interest rate (R) raised to the number of compound periods (nt) minus one. That means, CI = P[(1 + R)ⁿˣ – 1] Here,

P = Initial amount

R = Annual rate of interest as a percentage

n = Number of compounding periods in a given time

Given, 2500 dollars is invested at an interest rate of 5% compounded monthly.

From the above formula of compound interest

Total amount  A = P(1 + r/n)^nt

In our case

p = 2500

r = 5%

t = 4 years

Thus,

Total amount = 2500(1 + 5/12)^12 * 4

Total amount = 3051.02

therefore, this investment will be worth $3051.02 after 4 years.

(not 100% sure)

Step-by-step explanation:

Step-by-step explanation:

Basically 15x<30 is saying that 15x is less that 30. So that means x can be any number as long as when multiplied to 15 it has to be less then 30. So they only number available is 1. So 15(1)<30. Im not sure what the question is but X=1

Answer:

x < 2 or (-∞,2)

Step-by-step explanation:

Treat the inequality sign like an = sign at this point. Don't make it more complicated than it really is. So, to figure it out, you first need to divide each side by 15 so you can get x all by itself:

[tex]\frac{15x}{15} < \frac{30}{15}[/tex]

Now we have:

x < [tex]\frac{30}{15}[/tex]

We know (using simple math) that 30 divided by 15 is 2, which gives us:

x < 2.

In interval notation, this would be (-∞,2). [Remember that the parentheses show that the interval does NOT include the specified numbers, which is what < denotes in our equation.] Hope this helped!
