Answer:

120 security person

Step-by-step explanation:

the ratio is 1:170 so for every 170 people there is one security guard. So you take the number of people attending 20400 and divide by your ratio which is 170.

20400/170 = 120

Answer:

x = 6[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Using the sine ratio and the exact value

sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then

sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{6}{x}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )

x = 6[tex]\sqrt{2}[/tex]

The least number of seashells Jane collected is 56 seashells.

An inequality is an expression used to show the relationship between two or more variables and numbers.

Let j represent the number of seashells collected by Jane and t represent that of Tom, hence:

j > 2t + 8

For 24 seashells collected by Tom:

j > 2(24) + 8

j > 56

The least number of seashells Jane collected is 56 seashells.

Angles are the space between intersecting lines, and they are measured in degrees or radians

The measure of angle ABC is y + x

The given parameters are:

ABD=y,

DBC=x,

EFH=y,

EFG=x

PQS = SQR = x

To determine the measure of angle ABC, we make use of angle ABD and angle DBC

Note that angle ABD and angle DBC have common vertices at points B and D

So, we have:

ABC = ABD + DBC

Substitute known values

ABC = y + x

Hence, the measure of angle ABC is y + x

Answer:

I53 $

Step-by-step explanation:

So, now we can set up the proportion:

5.5             x

--------     =   ------

100              120

We need to find the value of x.

120 × 5.5 = 660

660 ÷ 100 = 6.6

So, now we know 6.6 is the amount Michael gets every year for interest.

Let's multiply that over 5 years.

5 × 6.6 = 33.

So, in total interest, Michael got 33$ in 5 years. Let's add that amount to the amount he originally added to into his savings account.

33 + 120 = 153.

Therefore, 153 will be the answer.

Functions can be represented using equations and graphs

The function that represents the magnitude of an earthquake, R, is [tex]r = \log(0.25a) + 2[/tex]

The equation of the function is given as:

[tex]r = \log(a/t) + d[/tex]

From the question, we have the following parameters

t = 4 seconds

D =2

So, the function becomes

[tex]r = \log(a/4) + 2[/tex]

Divide a by 4

[tex]r = \log(0.25a) + 2[/tex]

Answer:

see below

Step-by-step explanation:

Formula: [tex]speed=\frac{distance}{time}[/tex]

In Problem 1, the question is asking the rate of the vehicle in Trip A. This can be  interpreted as miles per hour; basically finding the speed.

Using the formula:

[tex]7,794[/tex] ÷ [tex]18[/tex] = [tex]433 mi/h[/tex]

Both values were plugged in and then divided, which narrowed it down to the final value/answer.

The rate of the vehicle was 433 miles per hour.

In Problem 2, the question is asking us the time traveled in Trip B. Basically the amount of time it took.

Once more using the formula, * This indicates DIVISION*

time = 7.2 hours

= 7.2 h

= 07:12:00

= 7 hours, 12 minutes, 0 seconds

The total time traveled in Trip B was 7 hours and 12 minutes.

In Problem 3, the question is asking the distance traveled in Trip C.

Using the formula one last time,

distance = 96 miles

= 96 mi

How I got this was through multiplication.

12 * 8 = 96.

Therefore, the distance traveled in Trip C was 96 miles.
