what does the ! after a number mean.
explain in your own words and give 5 examples.

Answer:

let the opposite angle of 43=y

57°+43°+y=180°[by sum of all angle is 180°]

100+y=180°

y=180°-100

y=80°

opposite angle of x is equal to the 80°

so the equation will be like this

x+x+80°=180°

2x+80°=180°

2x=180°-80°

2x=100

x=100/2

x=50°

so the value of x is 50°

D) -1/2

The domain is the set of input values for which the function is real and defined.

Find non negative values for the radicals.

For y = sqrt(3-x) if x is greater than the 3 the value under the square root would be negative which would result in a non real number.

The answer needs to be x <= 3 ( less than or equal to)

For y = sqrt(3x), if x is less than 0, the number under the sqrt root would be negative resulting in a non real number.

The answer is x >= 0 ( greater than or equal to)

Answer:

x(3+9)=72

or, x(12)=72

or, x=72÷12

or, x = 6 ans.

Answer: x=6

Step-by-step explanation:

Let's solve your equation step-by-step.

x(3+9)=72

Step 1: Simplify both sides of the equation.

12x=72

Step 2: Divide both sides by 12.

12x/12=72/12

x=6

Answer:

x=6

Answer:

150 degrees

Step-by-step explanation:

The degrees of a n-sided polygon is given by the expression:

180  (  n  −  2 )

where  n  is the number of sides. As we know that it ahs 12 sides, so

=180  (  12  −  2 )

=180  (  10 )

=1800 i.e. Therefore, there are  1800  degrees in a  12

-gon.

To find the measure of the angles, we know that the sum of all the angles is 1800 degrees, and there are 12 angles. So,

1800/12 = 150

So, the measure of the interior angle of a 12-gon is 150 degrees.

Answer:

[tex]-\frac{1}{55}[/tex]

Step-by-step explanation:

Hi! Ace here.

Whenever we have a positive being added to a negative, we can just do the positive subtracted my negative.

So let's rewrite this:

[tex]\frac{4}{5} -\frac{9}{11}[/tex]

When subtracting and adding fractions, we have to make sure there is a common denominator, and if there isn't a common denominator, then we make a common denominator. The LCM, in this case, is 55, so let's convert the fractions.

[tex]\frac{4}{5} *\frac{11}{11} =\frac{44}{55}[/tex]

[tex]\frac{9}{11} * \frac {5}{5} = \frac{45}{55}[/tex]

Since [tex]\frac{11}{11}[/tex] and [tex]\frac{5}{5}[/tex] both equal 1, the fraction is the same value.

Now we subtract normally with our "new" numbers.

[tex]\frac{44}{55}- \frac{45}{55}[/tex][tex]=-\frac{1}{55}[/tex]

I hope this helped, let me know if you have any questions.

Answer:

E

Step-by-step explanation:

The fractions have the same denominator so all you have to do is add the numerator, retain the denominator, and add the whole number.

Answer:

x = 80

Step-by-step explanation:

∡KJL = 180 - (60 + 40)

∡KJL = 80

∡XJK + ∡KJL = 180  (they are a linear pair of angles)

x + 20 + 80 = 180

x + 100 = 180

x = 80

Answer:

The Value of X in 2nd one can be 14√3.

The Value of X in 1st one can be 6√3.

Step-by-step explanation:

2.)here we used tan 60° formula with P/B as x/14 respectively.

as the value of tan 60° is √3, we got,

√3= x/14

x= 14√3.

1.) Here we used sin 30° formula with 1/√2 as P/H

so we got,

6/x= 1/√2

hence the answer comes:-

x= 6√2..

Hope so it helped you........

Answer:

X=3-(y/2)=8

Step-by-step explanation:

suppose the numbers is X

3 less than half the product of a number is 8

X= 3- (y/2)=8

Answer: See explanation

Step-by-step explanation:

Second term = a + d = 28 ....... i

Fifth term = a + 4d = 52 ......... ii

Subtract equation I from ii

3d = 24

d = 24/3 = 8

d = common difference = 8

Since a + d = 28

a + 8 = 28

a = 28 - 8 = 20

First term = a = 20

u10 = a + (n-1)d

= a + (10-1)8

= 20 + (9 × 8)

= 20 + 72

= 92

Answer:

they add up to 75 degrees

Step-by-step explanation:

the interior angles of a triangle always have to total to 180 degrees, so if one of them is 105 the other two are 180 - 105 = 75 degrees

Answer:

Each angle could possibly be 37.5

Step-by-step explanation:

the sum of all the angles inside a triangle is 180 degrees. If one angle is 105, then we take 105 from 180

180 - 105 = 75

75 is the measure of all the missing angles. since there are two missing angles, we can divide 75 by two for the two angles

75 divided by two is 37.5

Answer:

22 cubes are formed.

Step-by-step explanation:

Given that,

The diameter of the cylinder, d = 14 cm

Height of the cylinder, h = 49 cm

The side of the cube, a = 7 cm

Let there are n cubes formed. So,

[tex]n=\dfrac{\text{volume of cylinder}}{\text{side of cube}^3}\\\\=\dfrac{\pi r^2 h}{a^3}\\\\=\dfrac{\dfrac{22}{7}\times (7)^2 \times 49}{(7)^3}\\\\n=22[/tex]

Hence, there are 22 cubes that are formed.
