Answer:

124

Step-by-step explanation:

Answer:

24

Step-by-step explanation:

The formula for calculating the sum of interior angles is:

(n - 2) x 180°  (where n is the number of sides)

interior angle of a polygon = sum of interior angles ÷ number of sides

165 = [ (n - 2) x 180° ] ÷ n

Mulitply both sides by n:             165n = (n - 2) x 180°

Expand brackets:                         165n = 180n - 360

Add 360 to both sides:    165n + 360 = 180n

Subtract 165n from both sides:   360 = 15n

Divide both sides by 15:                 24 = n

Therefore, the number of sides = 24

Answer:

what is B^2 ?

ans - 1 byte2

Square root of B^2is ?

ans - Square root(byte^2) =

1 byte

The meaning of B² and the square root of B² are respectively; B × B and B

We want to know what B² represents.

Now, B² simply means a product of B × B.

This means that if we want to find the square root of B², the answer will be B because we have seen that B² = B × B

Answer:

Step-by-step explanation: Let's say you have 2 supplementary angles, x and y

So x + y = 180

if x is 79.6 degrees less than the measure of a supplementary angle, then x = y - 79.6

Putting this into our x + y = 180 equation, we get

(y - 79.6) + y = 180

2y - 79.6 = 180

2y = 180 + 79.6

2y = 259.6

y = 259.6/2 = 129.8 degrees.

so x = 129.8 - 79.6 = 50.2 degrees.

See if it worked. x = 129.8 degrees,  y = 50.2 degrees,    x + y = 180 so we found the correct two angles!

Answer:

x<=-4 or -2<=x<=2 or x>=4

Step-by-step explanation:

First, you have to get the formula in its standard form,

x^4 - 18x^2 + 64 >= 0

Next, you factorise the expression as you would any trinomial. The fact that the degree of the inequality is 4 instead of 2 just adds an extra step,

(x^2 - 16)(x^2 - 4) >= 0

Get the zeroes/critical values of the equation by equating either bracket to zero.

x^2 - 16 = 0  and  x^2 - 4 = 0

x^2 = 16                x^2 = 4

Since both values are positive, both answers are valid as squares of x. The aforementioned extra step is just square rooting these values. Remember: This means that both a positive and negative answer will arise from both equations.

x = 4 or x = -4 or x = 2 or x = -2

Now you have to show these values on a number line.

 -4     -2       2       4

_|____|____|____|_

These are the critical values of the inequality, i.e. those values that make it equal zero (zeroes). Now to solve the inequality you need to substitute a value larger than 4 (called x big positive) and then a value between 2 and 4, between -2 and 2... until you sub a value less than -4 into the factorised expression. The point of this is to get the SIGN of the answer. As a rule, since no factors repeat themselves, after calculating x big positive you can simply alternate the signs going left. Try it out yourself!

+ -4 -  -2  +   2   -   4  +

_|____|____|____|_

Since we're looking for values greater than or equal to zero, all critical values as well as "plus signs" will form part of the answer, namely:

x<=-4 or -2<=x<=2 or x>=4

P.S. If you prefer, you could also factorise each bracket further as both of them were DOTS brackets and you would have ended up with the same critical values.

Answer:

180 hours per week

Step-by-step explanation:

To find this answer, multiply all of the factors to get your answer

In this scenario, that would be 45x4

When you multiply this out, you get 180 hours

So your answer is 180 hours per week!

(By the way whoever created this problem doesn’t know simple time because there are only 24 hours in a day!)

Hope this helps!

Answer is [tex]No \: Solution[/tex]

EXPLANATION :-

Given

x-y= -5

x-y=1³

Substitute value of x - y as 1³ in first equation,

=> x-y= -5

=> 1³ = -5

As we can't do anything more to solve, we can finally write as :

so B 12 is the answer

a straight horizontal line is 180 degrees

box in the middle means that angle is 90 degrees

(s+1) + 90 + (2s-1) = 180

3s + 90 = 180

s = 30

Answer:

9.6 seconds

Step-by-step explanation:

The equation for projectile motion in feet is [tex]h(t)=-16t^2+v_0t+h_0[/tex] where [tex]v_0[/tex] is the initial velocity in ft/s and [tex]h_0[/tex] is the initial height in feet.

We are given that the initial upward velocity is [tex]v_0=150ft/sec[/tex] and the initial height is [tex]h_0=35ft[/tex]. Thus, plugging these values into our equation, we get [tex]h(t)=-16t^2+150t+35[/tex] as our equation for the situation.

The firework will land, assuming it doesn't explode, when [tex]h(t)=0[/tex], thus:

[tex]h(t)=-16t^2+150t+35\\\\0=-16t^2+150t+35\\\\t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\ \\t=\frac{-150\pm\sqrt{150^2-4(-16)(35)}}{2(-16)}\\ \\t=\frac{-150\pm\sqrt{22500+2240}}{-32}\\\\t=\frac{-150\pm\sqrt{24740}}{-32}\\\\t=\frac{-150\pm2\sqrt{6185}}{-32}\\ \\t=\frac{75\pm\sqrt{6185}}{16}\\\\t_1\approx-0.2\\\\t_2\approx9.6[/tex]

Since time can't be negative, then the firework will land after 9.6 seconds, assuming it doesn't explode at the time of landing.

Step-by-step explanation:

that is totally easy.

in the slope intercept form of a line equation the factor of x is always the slope.

in general

y = ax + b

a = the slope.

so, in our case here

y = 5x - 7

5 is the slope.

and -7 is the y intercept (at what point does the line intercept the y-axis; that is the y value when x = 0).

Answer:

x=2.1

Step-by-step explanation:

collect like terms 2.4x+5.8x=8.2x

move the terms to the left side and change its sign to -8.2x

move the constant(-3.28) to the right and change its sign to 3.28

equation should now be 9x-8.2x=-1.6+3.28

next you're going to do 9x-8.2x=0.8x

then -1.6+3.28=1.68

divide both sides of the equation by 0.8

x=2.1 is your final answer
