1 answer:
GalinKa [24]4 years ago
4 0

Answer:

20 and 50

Step-by-step explanation:

x + y = 70

y = 2x + 10

Use the substitution method:

y = 70 - x

y = 2x + 10

70 - x = 2x + 10

3x = 60

x = 20

x + y = 70

20 + y = 70

y = 50

<u>x = 20</u>

<u>y = 50</u>

295 feet = _____ meters ?
katen-ka-za [31]

Answer:

Hello! I hope I am correct!

Step-by-step explanation:

295 feet will equal to 89.916 meters.

Steps in order to solve this problem:

First you have to multiply the length in feet by 0.3048.

295x 0.3048 or 295* 0.3048

(295 feet is equivalent to 89.916 meters!)

Will equal 89.916 meters.

Therefore, 295 feet = 89.916 meter

Hope this helps!

What is the measure of AC?<br> Enter your answer in the box.<br> (4x - 5.5)<br> (5x+25)
Gnoma [55]

Answer:

The measure of arc AC is 85°

Step-by-step explanation:

we know that

The inscribed angle measures half that of the arc comprising

so

m∠ABC=(1/2)[arc AC]

substitute

(4x-5.5)°=(1/2)[5x+25]°

(8x-11)°=(5x+25)°

8x-5x=25+11

3x=36

x=12°

Find the measure of arc AC

arc AC=(5x+25)°

arc AC=5(12)+25=85°

All city blocks in sunnydale are the same size. Tina starts her paper route at the corner of two streets. She travels 8 blocks s
Elena-2011 [213]

Answer: 7 blocks west

Step-by-step explanation:

she goes 8 blocks south

13 blocks west

8 blocks north

and 6 blocks east.

the 8 blocks south and then north cancel each other out, so she is on the same street horizontally, but the 13 blocks west only get 6 blocks back east, so she ends up 7 blocks west of her starting point because 13 - 6 = 7

Rewrite the six trigonometric functions of theta in termsn of sin and or cosine of the reference anfle, sketch botht eh given an
Ede4ka [16]

There are mainly six trigonometric functions for right angle triangle which are

  1. sinФ
  2. cosФ
  3. tanФ
  4. cosecФ
  5. secФ
  6. cotФ

All of these can be expressed in the form of sinФ and cosФ as following:

  1. sinФ = sinФ
  2. cosФ = cosФ
  3. tanФ = sinФ/cosФ
  4. cosecФ = 1/sinФ
  5. secФ = 1/cosФ
  6. cotФ = cosФ/sinФ

This angle Ф is shown in the attached drawing in a right angle triangle drawn within a circle which is the given angle. Right angle is mentioned as "90".
