What is the simplified value of the expression below?
8.2 + 4.1 (6.3 minus 4)
9.43
17.63
28.29
73.49

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.

Hope this helps! :)

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.

30% of 420 are first year students

first year students = (30/100 )*420

=126 students

Student who are not in first year = 420-126

=294 students
