12/1x10/3 which equals to 120/3=40 =) id rlly understand question but hopefully dis will help =)
Step-by-step explanation:
The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
7×3 -4(225÷32)×2
7×3 -4(7.03)×2
21 - 8 (7.03)
21 - 56.25
= - 35.25
Answer:
D. 15cm2
Step-by-step explanation:
To find the area of a triangle, you multiply the base (10cm) and height of the triangle (3cm) and divide that by 2. So 10×3=30. Then, you need to divide this by 2. Since 30 is an even number, you won't get a decimal. So 30/2=15. And dont forget your units!
Area of a trap.= 1/2(base1+base2)x height
A=1/2(13+17) x 11
A=1/2(30) x 11
A=15 x 11
A=165 meter squared
