move the decimal point to the right of the 3 ( count the number of places you moved it) that would be the exponent and since you moved it to the right it would be negative
3.42 x 10^-6
26)
the sum of all internal angles=(sides-2)*180
720=(x/25-2)*180
4=x/25-2
6=x/25
150=x degrees per angle of A
use angle of A to calculate amount of sides of A:
150=(n-2)*180/n
150=180-360/n
360/n=30
12=n=sides of A
-> F
27)
Donald=500-6*t
Wendy=400-4*t
W=D
500-6t=400-4t
100-6t=-4t
100=2t
50=t
-> A
Answer:
55, 81, many different answers
Step-by-step explaination:
To find any answer to this problem do 26 times any number then add 3.
For example:
26x2=52
52+3=55 so...
55 divided by 2 would give you an answer of 26 r3
Answer:
87 cm²
Step-by-step explanation:
there is 1 triangle and 1 rectangle in the diagram. so you have to find the area of the both polygons and sum up to find the total area of polygon
area of triangle formula:
1) area of triangle AED
base = 12 cm
height = 4.5 cm
area:
area of rectangle formula:
2) area of rectangle ABCD
length = 12cm
height = 5 cm
area:
3) area of whole polygon
= area of triangle AED + area of rectangle ABCD
= 27 cm² + 60 cm²
= 87 cm²
