Answer:
2x1=2
Step-by-step explanation:
If it asks for 2, but he is making that one time he still needs to use 2.
'of' in math implies that the values are being multiplied together, so multiply 47 and 65%;
47 * 65% = 47 * .65 = 30.55
Answer:
Part 1) ![x=18\ units](https://tex.z-dn.net/?f=x%3D18%5C%20units)
Part 2) ![y=6\sqrt{3}\ units](https://tex.z-dn.net/?f=y%3D6%5Csqrt%7B3%7D%5C%20units)
Step-by-step explanation:
step 1
Find the value of x
we know that
In the right triangle of the figure
----> adjacent side divided by hypotenuse (CAH)
Remember that
![cos(30^o)=\frac{\sqrt{3}}{2}](https://tex.z-dn.net/?f=cos%2830%5Eo%29%3D%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B2%7D)
substitute
![\frac{\sqrt{3}}{2}=\frac{y}{12\sqrt{3}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B2%7D%3D%5Cfrac%7By%7D%7B12%5Csqrt%7B3%7D%7D)
![x=18\ units](https://tex.z-dn.net/?f=x%3D18%5C%20units)
step 2
Find the value of y
we know that
In the right triangle of the figure
----> opposite side divided by hypotenuse (SOH)
Remember that
![sin(30^o)=\frac{1}{2}](https://tex.z-dn.net/?f=sin%2830%5Eo%29%3D%5Cfrac%7B1%7D%7B2%7D)
substitute
![\frac{1}{2}=\frac{y}{12\sqrt{3}}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%3D%5Cfrac%7By%7D%7B12%5Csqrt%7B3%7D%7D)
![y=6\sqrt{3}\ units](https://tex.z-dn.net/?f=y%3D6%5Csqrt%7B3%7D%5C%20units)
Answer:
180cm^2
Step-by-step explanation:
split it into 2 different triangles one is 24 x 4 and the other is 24 x 11 then add them together
24 x 4 is 96/2 is 48
24 x 11 is 264/2 is 132
add 48 + 132 to get an answer of 180 cm^2
if anything doesnt seem right just comment and i will try and figure out what has gone wrong
hope this helps :)
gg easy
we want to cancel 1 term
first, get them into form am+bn=c where a, b, and c are constants
m-2n=2 is good
m+n=2(n-3) is m+n=2n-6 which is m-n=-6
compare constants
m's have 1 and 1
n's have -2 and -1
let's cancel m's
a. multiply 1st equation by -1
-m+2n=-2
add to 2nd equation
-m+2n=-2
<u>m-n=-6 +</u>
0m+n=-8
n=-8
sub back
m-n=-6
m-(-8)=-6
m+8=-6
m=-14
b. to check
m=-14 and n=-8
m-2n=2
-14-2(-8)=2
-14+16=2
2=2 yep
m-n=-6
-14-(-8)=-6
-14+8=-6
-6=-6 yep
so m=-14 and n=-8 is the solution
