Answer:
5/6
Step-by-step explanation:
Since 1/3÷2/5 can also be written as 1/3/2/5
So the ÷ can then be converted to × and 2/5 will change to 5/2
So let's solve
1/3×5/2
5/6
Since there is no common number that can divide the two
So the final answer is 5/6
The picture in the attached figure
let
x--------> men voters
y-------> women voters
we know that
y=x+2800------> y-x=2800------> equation 1
step 1find the percentage of women and men voters
in the graph
central angle by men voters=130°
central angle by women voters=(360°-130°)-------> 230°
by using proportion
men voters
%
women voters
%
remember equation 1
y-x=2800
so
F-M=63.89%-36.11%----> 27.78%
if 27.78% correspond to 2800 voters
100%---------------------->T
T=100*2800/27.78-------> T=10,079.19 voters
the answer isabout 10,079 voters
If it isnt in standard form already it would be 69000000
Answer:
(1, -9)
Step-by-step explanation:
4x + y = -5
8x + 3y = -19
If we have to use elimination, that means we're going to add or subtract these two whole equations by each other so that we can cancel out one of the variables.
I think that we could easily turn 4x into 8x if we multiply the top equation by 2.
4x + y = -5 ---> 8x + 2y = -10
Now put them next to each other, and subtract to get rid of the xs.
8x + 2y = -10
- 8x + 3y = -19
------------------------
0x - y = -10 - -19
-y = 9
y = -9
Plug this back in to get x.
4x + y = -5
4x - 9 = -5
4x = -5 - -9
4x = 4
x = 1
1) Formula: area = height * base / 2
2) Call x the height:
height = x
base = 2x
3) State the equation:
(x)(2x) = 49 in^2
4) Solve the equation:
2x^2 = 49 in^s
x^2 = (49/2) in^2
x = √(49/2) in
x = 7√2 / 2 in = 3.5 √2 in
5) Solution:
height = 3.5 √2 in and base = 7√2 in
6) Verification: area = (7√2 in) (3.5√2 in) = 49 in^2
Answer: height = 3.5√2 in and base = 7√2 in.
