Mathematics
1 answer:
Phoenix [80]3 years ago
8 0

Answer:

option A

Step-by-step explanation:

take 45 degree as reference angle

using sin rule

sin 45 = opposite / hypotenuse

\frac{1}{\sqrt{2} } = s/8\sqrt{2}

\frac{1}{\sqrt{2} } *8\sqrt{2} = s

root 2 and root 2 gets cancel

8 = s

Casey orders 3 pizzas and 2 orders of breadsticks for a total of 30.00. Rachel orders 2 pizzas and 3 orders of breadsticks for 2
barxatty [35]

Answer:

8

Step-by-step explanation:

x=pizza

y= breadsticks

3x+2y=30

2x+3y=25

first we myltiply the top equation with 3 and then w emultiply the lower equation with -2 so it is

9x+6y=90

-4x-6y= -50

now we can add them together and the y contracts

5x=40

now we divide it by 5

x=8

So pizza costs 8

Use the functions f(x) and g(x). to evaluate below.
svet-max [94.6K]

Given the graph and the table of functions, f(x) and g(x), the following <em>evaluated</em>:

a. f(0) = 9

b. g(2) = -3

c. f(-1) = 5

Given the functions, f(x) and g(x), the following can be <em>evaluated</em>:

<em><u>a. Find f(0):</u></em>

Using the table given, what we need to determine is the of the output, f(0) that an input value, x = 0, will give.

  • From the table, we see that when x = 0, f(x) =9.

<em>Therefore,</em>

f(0) = 9

<em><u>b. Find g(2):</u></em>

From the graph, find the corresponding value of g(x) that corresponds with x = 2.

  • From the graph, when x = 0, g(x) = -3

<em>Therefore,</em>

g(2) = -3

<em><u>c. Find f(-1):</u></em>

From the table, find the corresponding value of f(x) that corresponds with x = -1.

  • From the table, when x = -1, f(x) = 5

<u />

<em>Therefore,</em>

f(-1) = 5

It cost abigail $3.68 to send 92 text messages. how much does it cost to send one text?
iogann1982 [59]

It costs around $0.04 to send one text message.

Using unitary method, the cost of sending 92 text messages = $3.68

hence the cost of sending one text message = \frac {3.68}{92} = 0.04

the cost for sending one text message is 0.04.

<h3>What is text message?</h3>
  • Text messaging, or texting, is the act of composing and sending electronic messages, typically consisting of alphabetic and numeric characters, between two or more users of mobile devices, desktops/laptops, or another type of compatible computer.
  • Text messages may be sent over a cellular network, or may also be sent via an Internet connection.
  • The term originally referred to messages sent using the Short Message Service (SMS). It has grown beyond alphanumeric text to include multimedia messages using the Multimedia Messaging Service (MMS) containing digital images, videos, and sound content, as well as ideograms known as emoji (happy faces, sad faces, and other icons), and instant messenger applications (usually the term is used when on mobile devices).
