Answer:
m∠E=57°
Step-by-step explanation:
∠FDE=∠FED=(4x+1)° (base angles of isos triangle)
2(4x+1)+(5x-4)=180 (angle sum of triangle)
8x+2+5x-4=180
13x-2=180
13x=180+2
=182
x=182÷13
=14
Hence, m∠E = (4x+1)°
= [4(14)+1]°
= (56+1)°
= 57°
Answer:
First of all, the numbers are all positive numbers
They can all be divided by the number 3
They are all rational numbers, this means that they can be expressed as a ratio of two numbers
Answer:
An initial amount of 180 grows at a rate of 22% every month.
=> The equation for the amount y after x months:
y = 180 x (1 + 22/100)^x

Answer:
70% = 
20% = 
Step-by-step explanation:
We know that x% is represented by the fraction 
.
Now, in the first part, we are given two percentages 75% and 70%.
Now, 75% = 
and 70% =
Therefore, the second option is correct.
Again, in the second part, we are given two percentages 20% and 25%.
Now, 20% =
and 25% = 
Therefore, the third option is correct. (Answer)
