Answer:

x = 73.8

Step-by-step explanation:

to find the blue line:

tan(50) = 41/a

a = 41/tan(50)

a = 34.4 to 1 decimal place

to find x:

tan(65) = x/34.4

x = 34.4tan(65)

x = 73.8 to 1 decimal place

Answer:

3/12  and 5/x

12 times 5 is 60 so 3 times 20 shall be 60

3/12 = 5/20

Answer:

The second one !!

Step-by-step explanation:

You always start from the origin... (0, 0) !! From the bottom of that function, from the origin, you would move to the right 1, down 4 in order to get where the graph is in the picture !!

i hope this made sense... have a good day !

Answer:

[tex]\frac{1}{10}[/tex]

Step-by-step explanation:

We have a circle that is split in three sections, two of which we know and we are asked to find the third missing section.

For the circle, we know that 4/5 and 1/10 is fit. Now we need the last one, to solve, we need to get the same denominator and see how much is missing.

Since 1/10 is our highest denominator, let's change 4/5 to have 10 as a denominator. Which would be through multiplying 5 to get 10.

What times 5 equals 10?

2

Now multiply both numerator and denominator by 2 to get our portion.

[tex]\frac{4*2}{5*2}[/tex]

[tex]\frac{8}{10}[/tex]

Now we have the same denominator, let's add our two fractions and see how much we have left.

8/10 + 1/10

9/10

We have 1/10 missing, therefore 1/10 is the answer.

Answer:

[tex]100[/tex]

Step-by-step explanation:

[tex](2*5)^2[/tex]

First we need to start with the parentheses:

[tex](2*5)=10[/tex]

Now we have to do the power(2):

[tex]10^2\\10*10=100[/tex]

100 is your final answer.

Answer:

7ab

y³

e/f

Step-by-step explanation:

a*b*7= 7ab

y*y*y= y³

[tex]\frac{x^n}{x^y}=x^{n-y}\\\\\frac{e^3*f}{e^2*f^2}=\frac{e}{f}\\[/tex]

Answer:

a) 7ab

b) y^3

c) e/f

Step-by-step explanation:

a) when multiplying two variables, u can just put them right next to each other, e.g. b x c = bc

when numbers are added, same goes, they just go before the variable, hence the 7ab. If u had something like 7ab x 8 then you'd just multiply the 8 with the 7 and get 56ab

b) imagine y= 2. if u had 2 x 2 x 2, that would be 8 which is also 2^3. When any number is multiplied by itself n times, it's raised to that power. which is why y x y x y = y^3. y is being multiplied by itself 3 times.

c) If u had [tex]\frac{4*2}{2}[/tex], that would = 8/2 = 4 because it would simplify. in the fraction, you could also reduce the 2 since it appears in both the numerator and denominator.

same thing here: both the numerator and denominator have 2 e and 1 f so they get crossed out, leaving e/f

hope this helps!

Answer:

x= 4.5

Step-by-step explanation:

P= 2(l + w)

36 = 2(4x-6)+12

36 = 8x - 12 +12

x = 36/8

=4.5

Answer:

Equation: 4x - 6 = 6            x = 3

Step-by-step explanation:

A rectangle is a parallelogram, which means that opposite sides are parallel.  This means that both of the short sides equal 12.  12 plus 12 is 24, so substract 24 from 36 to get 12.  This means that the sum of the long sides are 12; half of 12 is 6 so that is the length of one of the sides.  This means that you can set the equation 4x - 6 equal to 6.  Add 6 to both sides to get 4x = 12, then divide both sides by 4 to get x = 3.  I think your equation should be 4x - 6 = 6, and x equals 3.  

Sorry if I'm wrong, if I'm right then that picture of the rectangle is really misleading.
