We at present undergo the following operations: addition, subtraction, multiplication, and division. When given an expression sometimes we confuse operations which must take precedence.
In the 1500s the rules of the order of operation were issued. The "order" of these operations states which processes take precedence (as a priority) before which other operations.
The priority of operations is:
Brackets (simplify in it)
Exponent
Multiplication and Division (from left to right)
Addition and Reduction (from left to right)
Find the area of a triangle with legs that are: 9 mm, 6 mm, and 12 mm.
A. 26.1 mm
B. 12.3 mm
C. 11.6 mm
D. 37 mm?
Answer:
Step-by-step explanation:
a = 9 mm ; b = 6 mm ; c = 12 mm
S = (a + b +c) / 2
[tex]= \dfrac{9 + 6 + 12}{2}\\\\= \dfrac{27}{2}\\\\= 13.5 \ mm[/tex]
S - a = 13.5 - 9 = 4.5 mm
s -b = 13.5 - 6 = 7.5 mm
s -c = 13.5 - 12 = 1.5 mm
Area = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
[tex]= \sqrt{13.5 * 4.5 * 7.5 * 1.5} \\\\= \sqrt{683.4375} \\\\=26.1 \ mm^{2}[/tex]

Solve the combined inequality.
Items in a store range from $1.85 to $12.83 including tax.
What range of values describes the total purchase price for 5 items?
Enter your answer by filling in the boxes.
≤x≤
Answer:
9.25≤x≤64.15
Step-by-step explanation:
The smallest amount would be 5 of the least priced item
5 * 1.85 =9.25
The largest amount would be 5 of the greatest priced item
5 * 12.83 =64.15
9.25≤x≤64.15
2.)Name the number system in which only the whole number less than 5 are used:
Answer:
(a) x = 40°
Step-by-step explanation:
(2x+43)°+(2x-3)°=180°
4x+40°=180°
x=40°
10- 3/4z = 8
Somebody, please help me! I don't get this!
Answer:
z = 8/3
Step-by-step explanation:
10- 3/4z = 8
Subtract 10 from each side
10-10- 3/4z = 8-10
-3/4z = -2
Multiply each side by -4/3
-3/4z * -4/3 = -2 *4/3
z = 8/3
Findi the value of x
Answer:
By Pythagoras theorem ,
H^2 = P^2 + B^2
H^2 = 4^2 + 3^2
H^2 = 16 + 9
H^2 = 25
H = 5
therefore , value of x = 5
hope that helps uh..☺
Answer:
x = 5
Step-by-step explanation:
Since it's a right triangle, you can use Pythagorean Theorem.
[tex]a^2+b^2=c^2\\3^2+4^2=x^2\\9+16=x^2\\25=x^2\\5=x[/tex]

Solve for p.
−160=22+8(3p−4)
Answer:
[tex]p=-6.25[/tex] or [tex]p=\displaystyle-\frac{25}{4}[/tex]
Step-by-step explanation:
[tex]-160=22+8(3p-4)[/tex]
Our goal here is to isolate p on one side of the equation. We will do this by performing inverse operations on both sides.
Subtract 22 from both sides:
[tex]-160-22=22+8(3p-4)-22\\-182=8(3p-4)[/tex]
Divide both sides by 8:
[tex]-22.75=3p-4[/tex]
Add 4 to both sides:
[tex]-22.75+4=3p-4+4\\-18.75=3p[/tex]
Divide both sides by 3:
[tex]-6.25=p[/tex]
You can also convert this into a fraction:
[tex]p=\displaystyle-\frac{25}{4}[/tex]
I hope this helps!
What is the area of this figure?
4 m
3 m
2 m
3 m
2 m
9 m
6 m
5 m
Write your answer using decimals, if necessary.
square meters
Answer:
63
Step-by-step explanation:
Area = large rectangle + small rectangle + triangle
A = (L1 * W1) + (L2 * W2) + 1/2 base * heigth)
A = (9 * 5) + (2 * 3) + 1/2(((2 + 5 + 2) - (3)) * 4))
A = 45 + 6 + 1/2((9 - 3) * 4)
A = 51 + 1/2(6 * 4)
A = 51 + 1/2(24) = 51 + 12 = 63
Solve. x/8 + 2 = 27
3(x - 5) = 30
I dont know how to solve this
Answer:
x=15
Step-by-step explanation:
3(x-5)=30
First, you would distribute the three to the x and the negative five.
3x-15=30
Then you would add 15 to the 15 to cancel it and to the 30 to make it even.
3x-15=30
+15=+15=
3x=45
Finally, you would divide 3 into both sides, cancelling out the three and fiving you,
x=15
Hope this helped!
Start by distributing the 3 through the parenthses on the left side.
This gives us 3x - 15 = 30.
Now add 15 to both sides to end up with 3x = 45.
Dividing both sides by 3, we fin that x = 15.

JC is making a poster for Bike Safety Week. The diameter of circle A is 16 in.
If the area of circle B is of the area of circle A, what is the area of circle B? Use = 3.14.
Answer:
Circle B has an area of 200.96 in².
Step-by-step explanation:
π = 3.14
radius of circle A = diameter of circle A/2
= 16 in/ 2 = 8 in.
Area = πr² = (3.14)(8²)
= (3.14)(64)
= 200.96 in²
