Write the measure 29° 6' 6" as decimal to the nearest thousandth.

1 answer:

6 0

This angle is "29 degrees 6 minutes 6 seconds".

-- There are 60 minutes in 1 degree.
   So 1 minute = 1/60 degree.

-- There are 60 seconds in 1 minute.
      So 1 second = 1/60 minute = 1/3600 degree.

29 6' 6" = (29)° + (6/60)° + (6/3600)°

   = (29)° + (0.1)° + (0.001666...)°

   = 29.101666...°

Rounded to the nearest thousandth of a degree: 29.102°

A: 2,5
B: 3,1
C: -2,4

Explanation:

When you’re moving right and up you would add however many numbers you moved up to the original points because going right on a graph makes the X a larger number, and going up makes it larger.

Please help me with this question!!

quester [9]

Answer:

Step-by-step explanation:

a1 = 6

a2 = 10

a3 = 14

The next member of the sequence is 4 more than the current sequence. Therefore d = 4

a1 = 6

d = 4

n = 13

an = a1 + (n - 1)*d

an = 6 + (n - 1)*4

a_13 = 6 + 12*4

a_13 = 6 + 48

a_13 = 54

Rewrite (123 + 456) + 789 using the Associative Law of Addition

adelina 88 [10]

Answer:

123 + (456 + 789)

Step-by-step explanation:

since this is an addition problem, the parenthesis don't matter, and they can be put wherever you want.

(123 + 456) + 789

123 + 456 + 789

(123 + 456 + 789)

123 + (456 + 789)

technically, any of these would work, but I think the kind of answer the problem is looking for is;

123 + (456 + 789)

Shawn earns $12.75 per hour. How many hours does she need to work to earn $102 or more. Write and solve an inequality.

astra-53 [7]

First we divide 102 by 12.75 to get the hours which is 8 hours. So it would take 8 hours

X-y=6<br> 2x-3z=16<br> 2y+z=4<br><br> Solve the systems of equations.

Neko [114]

Answer:

Given System of equation:

x-y =6 .....,[1]

2x-3z = 16 ......[2]

2y+z = 4 .......[3]

Rewrite the equation [1] as

y = x - 6 .......[4]

Substitute the value of [4] in [3], we get

$2(x-6)+z = 4$

Using distributive property on LHS ( i.e, $a \cdot (b+c) =a \cdot b+ b \cdot c$ )

then, we have

2x - 12 +z =4

Add 12 to both sides of an equation:

2x-12+z+12=4+12

Simplify:

2x +z = 16 .......[5]

On substituting equation [2] in [5] we get;

2x+z=2x -3z

z = -3z

Add 3z both sides of an equation:

z+3z = -3z+3z

4z = 0

Simplify:

z = 0

Substitute the value of z = 0 in [2] to solve for x;

$2x-3(0) = 16$

2x = 16

Divide by 2 both sides of an equation:

$\frac{2x}{2} =\frac{16}{2}$

Simplify:

x= 8

Substitute the value of x =8 in equation [4] to solve for y;

y = 8-6 = 2

y = 2

Therefore, the solution for the given system of equation is; x = 8 , y = 2 and z =0
