Find the slope of a parallel line -10+x-2y=0

Answer:

It's a mnemonic device to help you remember the three basic trig ratios used to solve for missing sides and angles in a right triangle. It's defined as: SOH: Sin(θ) = Opposite / Hypotenuse. CAH: Cos(θ) = Adjacent / Hypotenuse.

Answer:

SOH CAH TOA is a mathmatical acronym used in triginometry. It helps find missing angels and sides of a triangle.

Step-by-step explanation:

Sine = Opposite side over Hypotenuse         ---> SOH

Cosine = Adjacent side over Hypotenuse       ---> CAH

Tangent = Opposite side over Adjactent          ---> TOA

You use SOHCAHTOA to find the angle. You use the inverses to find the measures.

Answer:

sqrt(24)

Step-by-step explanation:

The square root of 24 is between 4 and 5 since we know that 4 square is 16 and 5 squared is 25.  16 < 24 < 25.

Answer:

99.9453% of matter in the ore is neither diamond or copper

Step-by-step explanation:

First add  0.0297 and 0.025

0.0297+0.025=0.0547

Now subtract 0.0547 from 100

100-0.0547=99.9453

99.9453% of matter in the ore is neither diamond or copper

Answer:

x = 11

Step-by-step explanation:

        Simplify [tex]2(x-3)+7[/tex]

        Apply the distributive property.

[tex]2x - 6 + 7= 23[/tex]

[tex]2x+1=23[/tex]

         Move all terms not containing  x  to the right side of the equation.

         Subtract  1  from both sides of the equation.

[tex]2x =23-1[/tex]

[tex]2x=22[/tex]

          Divide each term by  2  and simplify

[tex]\frac{2x}{2} = \frac{22}{2}[/tex]

          Cancel the common factor of  2

[tex]x = \frac{22}{2}[/tex]

          Divide 22 by 2

[tex]x = 11[/tex]

Answer:

No

Explanation:

The unit rates are not the same.

Answer:

Positive; P increases

Step-by-step explanation:

When gasoline prices go up, the demand for push lawn mowers increases, so the sign of the cross-elasticity is positive.

If gasoline prices go up, and demand for push lawn mowers goes up, then the price for push lawn mowers will also go up.

Answer:

x = -2

Step-by-step explanation:

6(x+7)=30

6x+42=30

6x=-12

x=-2

Step-by-step explanation:

Hey there!!

According to the question,

One number is 7.

Let another no. be x.

So, the condition is 6(x+7)= 30

Now,

6(x+7) = 30

6x +42 = 30

6x = 30-42

[tex]x = \frac{ - 12}{6} [/tex]

Therefore the no. is -2.

Check,

6(-2+7)= -12 + 42 = 30 { they gets subtracted but sign remains (+) only }.

Hope it helps....

Plug in all numbers to table and find the correct answers. Use coordinating x and y numbers

Answer: 0.42%.

Step-by-step explanation:

Probability of (M(Eligible Men)) = 0.52

Probability of (W(Eligible Women)) = 1 - 0.52

= 0.48

Probability of (UM(Unemployed Men)) = 0.088

Probability of (UW(Unemployed Women)) = 0.070.

therefore;

Probability that the worker is a man = [P(UM)*P(M)]/[P(UM)*P(M) + P(UW)*P(W)] = 0.576613

0.088 * 0.52 )/ 0.088 * 0.52 + 0.070 * 0.48

= 0.04576 / 0.07936

= 0.5766

probability that the randomly selected worker is both female and unemployed is

= 1 – 0.58%

= 0.42%

Answer:

Step-by-step explanation:

Given the expression  |x|=a, we must understand that  |x| can return both positive and negative value of x i.e

x=a and -x = a

from the second equation,

-x = a

multiply both sides by minus

-(-x) = a

x = -a

Hence If "a" is negative number according to the question then the  equation has one solution which renders the fact that the equation has no solution if a is negative false.

Step-by-step explanation:

2n-1/4=0

Add 1/4 to each side

2n-1/4+1/4=1/4

2n = 1/4

Divide each side by 2

2n/2 = 1/4 * 1/2

n = 1/8
