Answer: 66.5 inches

Step-by-step explanation:

Answer:

x = 120

z = 21

Step-by-step explanation:

x and 60 are supplementary, so added together they make 180.

x + 60 = 180

subtract 60 from both sides

x = 180 - 60

x = 120

next, x and 4z+36 are equal, so you can make this equation:

x = 4z + 36

substitute x for 120 as established earlier.

120 = 4z + 36

subtract 36 from both sides

120 - 36 = 4z

84 = 4z

divide both sides by 4

84/4 = z

21 = z

Answer:

[tex]4y = 16-2x\\y = \frac{16}{4} - \frac{2x}{4}\\ y = \frac{-1x}{2}+4\\y = 0.5x+4[/tex]

Given parameters:

  Equation of the straight line;

                    2x + 4y = 16

The slope intercept form of the equation is y = mx + c

Where m is the slope of the line

            y and x are the coordinates

             c is the intercept

So, the problem is to write the given equation in form of y = mx + c;

         2x + 4y = 16

                 4y = 16 - 2x

  Divide through by 2;

                 [tex]\frac{4y}{2}[/tex]   = [tex]\frac{16}{2}[/tex] - [tex]\frac{2x}{2}[/tex]

                  2y = 8 - x

                    2y = -x + 8

 Then divide by 2 all through;

                    [tex]\frac{2y}{2}[/tex] = [tex]\frac{-x}{2} + \frac{8}{2}[/tex]

                   y = [tex]\frac{-x}{2} + 4[/tex]

The equation of the line is y = [tex]\frac{-x}{2} + 4[/tex]

Answer:

86 degrees

Step-by-step explanation:

Alrighty, a simple 180-degree triangle, we can see that the two angles add up to 86, so what would make our angle G1 94 since 180-86 = 94, but we are tasked with finding the other side of that angle, let's call it G2, what should we do?

Since this is a flat 180-degree line, we do it again!

180-94 = 86 degrees

And there ya have it

Though, if you need the technical side, it's because a whole of a triangle is 180 degrees

Given that angles F is 58 and E is 28, we add those two up to find angle EGF. How to find EGF you ask? Simple- 180 degrees (Because it's a triangle) minus 86 (Added angles of E and F), that would equal 94.

Now, we are tasked with finding TGF. We do not have TGF but we have EGF. Learning that, we see the line ET, indicating that we have found ourselves a 180-degree line. What do we do with this line? We use it to calculate TGF with EGF

Since EGF is 94, we take the 180 - 94 to equal 86, and that is how you find TGF

Hey there!

Problem A.
((-10)^3 * 6)^3

= ((-10)(-10)(-10) * 6)^3

= (100(-10) * 6)^3

= (-1,000 * 6)^3

= (-6,000)^3

= (-6,000)(-6,000)(-6,000)

= 36,000,000(-6,000)

= 216,000,000,000

Thus, your answer is: 216,000,000,000

Problem B.
(3^2/5)^3

= (3 * 3 / 5)^3

= (9/5)^3

= 9/5(9/5)(9/5)

= 9 * 9 * 9 / 5 * 5 * 5

= 81 * 9 / 25 * 5

= 729 / 125

≈ =5 104 / 125

≈ 5.832

Thus, your answer is:

5.832 , 5 104/125, or 729 / 125

EITHER OF THOSE SHOULD BE CORRECT BECAUSE THEY ARE EQUIVALENT TO EACH EACH OTHER!

Good luck on your assignment & enjoy your day!

The minimum qualifying score to join the genius society is 130, the correct option is B.

In the top 2%, you have to have an IQ higher than 98% of the population (100% - 2%). This is also known as the 98th percentile.

Given

A genius society requires an IQ that is in the top 2% of the population in order to join.

If an IQ test has a mean of 100 and a standard deviation of 15.

For this problem, you are given the probability and need to determine the raw score.

For the probability, go to the z–table and find the probability that is closest to 0.98. Then look across the row and up the column to determine the z-score.

The closest probability is 0.97982 and that corresponds to a z-score of 2.05.

With a z-score of 2.05, you can use the z formula to compute the raw score.

[tex]\rm z-score=\dfrac{X- mean }{Standard \ deviation}\\\\2.05=\dfrac{x-100}{15}\\\\2.05 \times 15 = x-100\\\\30 +x-100\\\\x=100+30\\\\x = 130[/tex]

Hence, the minimum qualifying score to join the genius society is 130.

Answer:

I'm sorry I couldn't answer in time but I believe it to be 60.. I might be wrong though.

Answer:

We do this by first converting all terms into fractions, finding the least common denominator (LCD), then rewriting each term as an equivalent fraction with the LCD. Then we compare the numerators of each fraction and put them in correct order from least to greatest or greatest to least.

The positive solution to the equation [tex]-x^{2} +2x+1=0[/tex] is [tex]x=1+\sqrt{2}[/tex].

Given quadratic equation is:

[tex]-x^{2} +2x+1=0[/tex]

The general form of a quadratic equation is [tex]ax^{2} +bx+c=0[/tex] and [tex]a\neq 0[/tex].

On comparing with general form of quadratic equation

a = -1

b = 2

c = 1

So, from the Shreedharacharya formula,

[tex]x = \frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex]

[tex]x = \frac{-2+-\sqrt{2^{2} -4(-1)(1)} }{2*(-1)}[/tex]

[tex]x = 1-\sqrt{2} \\x=1+\sqrt{2}[/tex]

as [tex]x = 1-\sqrt{2}[/tex] is negative

So, the positive solution is [tex]x=1+\sqrt{2}[/tex]

Therefore, the positive solution to the equation [tex]-x^{2} +2x+1=0[/tex] is [tex]x=1+\sqrt{2}[/tex].

Answer:

The percent is 4.9471%

Step-by-step explanation:

Here, we want to find the percentage of observations that lie above z = 1.65

Firstly we find the probability of x < z = 1.65

Hence P ( x > 1.65)

This is obtainable from the standard normal distribution table

The value of P(x > 1.65) = 0.049471

This represents a percentage of 4.9471%

Answer:

4.95/4.9471 is correct

ED2021

from the first equality we have

3x - 6y = 2

3x = 2 + 6y

x = 2/3 + 2y

we replace x by this value in the second equality

4 * (2/3 + 2y) + 3y = -1

8/3 + 2y + 3y = - 1

5y = - 3/3 - 8/3

5y = - 11/3

y = -11/15

and we can get x now :

and x = 2/3 + 2*(-11/15)

x = 2/3 - 22/15

x = 10/15 - 22/15

x = - 12/15

check

3 * (-12/15) - 6 * (-11/15) = -36/15 + 66/15 = 2
