Answers

Answer 1

Answer:

Answer:

11/-30 Hope this helped :)

Step-by-step explanation:

15x + 4 = -1 1/2

15x = -5 1/2

x = 11/-2*1/15

x = - 11/-30

Suppose a triangle has two sides of length 3 and 4 and that the angle between these two sides is 60°. What is the length of the third side of the triangle?

Answers

There is many way how to get the length of a triangle. You can use many method but to your question the best method to use is Law of sine and cosine Side Angle Side triangle formula. This formula is this one (a^2 = b^+c^2-2bc*cos(angle)). So if your fill it up it would be (a^2 = 3^2+4^2-2*3*4*cos(60)). The answer would be 3.61

The length of the third side is 3.6 units

How to determine the length of the third sides?

Let the sides of the triangle be;

x, y and z

So, we have:

x = 3

y = 4

<Z = 60

The length of the third side is then calculated using the following law of cosine

z^2 = x^2 + y^2 - 2xy cos(Z)

So, we have:

z^2 = 3^2 + 4^2 - 2 * 3 * 4 * cos(60)

Evaluate the exponents and the product

z^2 = 9 + 16 - 12

Evaluate the sum and the difference

z^2 = 13

Take the square root of both sides

z = 3.6

Hence, the length of the third side is 3.6 units

Divide both sides by 23 to get the width by itself and you get
37=W or the width is 37 meters

A man spent exactly $2.50 on 3¢, 6¢, and 10¢ stamps. If he bought ten 3¢ stamps andtwice as many 6¢ stamps as 10¢ stamps, how many 10¢ stamps did he buy?

Answers

You have 2.50.
3 times 10 is 30, so now you have
2.20.
he bought twice as many six cent stamps as ten cent stamps.
multiples of six that are applicable are 30, 60, 90, 120.
six goes into 30 five times. Five can't be divided in half.
six goes into 60 ten times. ten divided in half is five. fifty plus sixty, is only 110.
six goes into ninety 15 times. fifteen can not be divided in half.
six goes into 120 twenty times. 20 divided in half is ten. ten times ten is 100.
100 + 120 = 220.
He bought 10 10cent stamps

1stamp i believe. Due to .03•10=.30 and 2.50-.30=2.20 so i divided By .6 and got 3.67 so just find where .10 fits. I know im no help

2. The Salton Sink in California is approximately 215 feet below sea level. Which of the following best describes the location of the Salton Sink as it relates to sea level?

a –215
b 0
c +215
d +2150

Answers

We need to find the best way to represent the numbers.

The score will be best represented by $+4$

The depth of the Salton Sink will be best described as $-215$ .

$4$ under par means that it took $4$ less strokes than the par of the course to complete the course.

This represented by $-4$

The negative sign comes first.

If the score is $4$ over par then it took $4$ more strikes than the par of the course.

This score will be best represented by $+4$

Let, us take the surface sea level as $0$ .

So, the depth below the sea level will be negative and above it will be positive.

Hence, the depth of the Salton Sink will be best described as $-215$ .

This is a bit of a guess, but I think probably a) +4 and also a) -215
