Remove the unnecessary brackets
2.31 x 10^-6+3.41 x 10^3
Convert the decimal to a fraction
231/100 x 10^-6 + 3.41 x 10^3
Multiply
231/100 x 1/10^6 + 3.41 x 1000
Combine
231/100 x 1/10^6 + 3410
Calculate
231/(10^2 x 10^6) + 3410
Answer:
231/10^8 + 3410

Step-by-step explanation:
5/7
Sum of a geometric series is a/(1-r) = 1/(1-(-2/5)) = 5/7
Answer: It is around 115 if that helps
Step-by-step explanation:
I think the answer is one.
I think this because since it’s times you would do backwards and divide 0.89 divided by 0.89 and you would get 1. I hope I’m correct sorry if I’m not.
Use pythagoras to find the 3rd length of the triangle:
Square root of 8.5^2-7^2= 4.82 yd
Find the area of the trapezium:
((2+(2+4.82))x7)/2
= 30.87 yd^2
To find the area of the parallelogram you just take away the area of the triangle from the area of the trapezium:
Area of triangle is (4.82x7)/2= 16.87yd^2
