Find the area use 3.14 for pi
Answer:
15.14 cm^2
Step-by-step explanation:
Area of rectangle = 4cm x 3 cm = 12cm^2
Radius of the circle = 2 cm
Area of 1/4 of a circle = (pi x r^2) / 4
= (3.14 x 4) / 4 = 3.14 cm^2
3.14 cm^2 + 12cm^2 = 15.14 cm^2

what is the value of the expression 1/2 (m-2/3n) when m=3/2 and n= 1/2 ?
a. 5/12
b. 7/12
c. 11/12
d. i don’t know
Answer:
B.[tex]\frac{7}{12}[/tex]
Step-by-step explanation:
[tex]m=\frac{3}{2}\\n=\frac{1}{2\\} \\\frac{1}{2} (m-\frac{2}{3} n)=\frac{1}{2} (\frac{3}{2} -\frac{2}{3} .\frac{1}{2} )\\=\frac{7}{12}[/tex]
So B is the correct answer.
Expression is a combination of operators, variables and numbers.. The value of the expression 1/2 (m-2/3n) when m=3/2 and n= 1/2 is 7/12.
What is Expression?Expression is a combination of operators, variables and numbers.
The given expression is one by two times of m minus two by three times n.
1/2 (m-2/3n)
where m and n are two variables with values m equal to three by two 3/2 and n equal to one by two.
1/2 (3/2-2/3(1/2))
Firstly we solve the value in parenthesis.
1/2 (3/2-1/3)
LCM of two, three is six
1/2 ((9-2)/6)
Subtract nine and two we get seven
1/2 (7/6)
Now one by two times of seven by six
7/12
So value of the expression 1/2 (m-2/3n) when m=3/2 and n= 1/2 is 7/12.

Please I actually need this done
Answer:
AC = 19
Step-by-step explanation:
A__C__S
AS = AC + CS
6x -4 = (4x-1) + 7
6x - 4 = 4x + 6
6x - 4x = 6+ 4
2x = 10
x = 10/2
x = 5
AC = 4x -1 = 4(5) - 1 = 20 - 1 = 19
I hope I helped you^_^
Answer:
19
Step-by-step explanation:
AS = AC + CS
6x - 4 = 4x -1 +7
6x - 4 = 4x + 6
Add 4 to both sides,
6x = 4x + 6 + 4
6x = 4x + 10
Subtract 4x from both sides
6x- 4x = 10
2x = 10
Divide both sides by 2
x = 10/2
x = 5
AC= 4x - 1
= 4*5 - 1
= 20 - 1
= 19

If we already know that B=34 we need to find out the rest.
B=50 (Estimated)
D=45 (Estimated)
34+50+45
34+50=84+45=129, 129 estimated=130, and since their is no answer choice but C it should be C, I could be very wrong though.
