Answer:6y
Step-by-step explanation:
Use PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). Solve the problem in that order.
In this case, you would first solve the parentheses (6.3-4) to get 2.3. The problem is now 8.2+4.1(2.3). Next, multiply 4.1*2.3 to get 9.43. The problem is now 8.2+9.43. After adding, the only thing that remains is 17.63.
So, the answer is B 17.63.

Answer:
x1 = 1 x2= 1/2
Step-by-step explanation:
DELTA= b^2-4*a*c
DELTA=(-6)^2-4*4*2= 4 >0 ==> 2 solutions
x1 = (-b+sqrtDELTA)/2*a = (6+2)/2*4 = 1
x2 = (-b-sqrtDELTA)/2*a = (6-2)/2*4 = 1/2
Two <em>possible answers</em> are:
23.65 and 23.72.
Explanation:
For the first number, 23.65, we are rounding to the tenths place. 23.65 itself is smaller than 23.7. Looking behind the tenths place, the digit behind it is 5. This means we round the tenths place up; this becomes 23.7.
23.72 is larger than 23.7. We will round it to the tenths place as well. Looking behind the tenths place, we have a 2; this means we "round down." This means leave the 7 as it is and drop the other digits behind it. This gives us 23.7.
Answer:
640 units squared
Step-by-step explanation:
First, the formula of a trapezoid is (a + b) x 2 divided by h
So, 40 + 24 = 64
64 x 20 = 1280
and 1280/2 = 640
