Answer:
part a and b only i was actually looking for c
Step-by-step explanation:
for part b
Area of DEF= 1/2× base × height = 1/2× 2 × 1 = 1
Area of FGD= 1/2× base × height = 1/2× 2.24 × 1.34 =1.50
Area of GBD= 1/2× base × height = 1/2× 2 × 1 = 1
Area of ABG= 1/2× base × height = 1/2× 4.12 × 0.49 =1.01
Area of BCD= 1/2× base × height = 1/2× 1.41 × 2.12 =1.49
The approximate area of the original polygon is 6 square units
Answer:
1) Area = 12cm²
2) x = 5cm
Surface area : 69cm²
Step-by-step explanation:
Opposites sides in a rectangle would equal the same.
so Top/bottom = 20+20=40
Front/back = 15+15=30
40+30=70cm²
94-70=24cm² for left and right side 24÷2=12cm²
2) Those lines represents what side it is equal too which also means the same.
3cm, you know that base x height = surface area so surface area ÷ height = base
15/3=5cm
x=5cm
Formula : Base x Height = One surface area
Front/Back= 15+15=30
Top/bottom = 5x3 = 15+15=30
side/side = 3x3=9
30+30+9=69cm²
Answer:
17/72
Step-by-step explanation:
Let's make this equation easier to read.
.5/36 + 16(1/72)
Start by remembering PEMDAS
Parentheses
Exponents
Multiply
Divide
Add
Subtract
This is the order in which you will solve the problem. So multiplication first, then division, and finally addition.
Multiply 16 and 1/72
16/1 x 1/72 multiply across to get 16/72 which can be reduced to 2/9.
Divide .5 (or 1/2) by 36. To do this, multiply by the reciprocal of 36
1/2 x 1/36 = 1/72
Your equation is now
2/9 + 1/72
Your common denominator is 72, so multiply top and bottom of 2/9 by 8.
16/72 + 1/72 = 17/72
6(a-7)(a^2-2)
thats the answer for your quesion
(7*4)+(7*5)
cause since it is 7*9 4+5 equals 9
