For the 1st one it is:
85% of 1600 is 1,360
For the 2nd one it is:
816 of 850 is %96
X=40.
-6x+10x=160
4x=160 divide by 4 on both sides
And your answer is 40
B1 = 2
b2 = (b1)^2 + 1 = 2^2 + 1 = 5
b3 = (b2)^2 + 1 = 5^2 + 1 = 26
b4 = (b3)^2 + 1 = 26^2 + 1 = 676+1=<span>677</span>
Answer:
55 cm²
Step-by-step explanation:
side length of square = perimeter/4 = 40/4 = 10 cm.
area of square = side x side = 10 x 10 = 100 cm²
area of triangle #1 = 1/2bh = 1/2(3)(10) = 15
area of triangle #2 = 1/2bh = 1/2(6)(10) = 30
100 - 15 - 30 = 55 cm²
Answer:
You can alternatively apply PEMDAS as schools do today: Simplify everything inside the parentheses first, then exponents, then all multiplication and division from left to right in the order both operations appear, then all addition and subtraction from left to right in the order both operations appear.
Step-by-step explanation:
PEMDAS is an acronym for the words parenthesis, exponents, multiplication, division, addition, subtraction. Given two or more operations in a single expression, the order of the letters in PEMDAS tells you what to calculate first, second, third and so on, until the calculation is complete.
so 8+4 =12 12-3=9
