Answer:
20 cm
Step-by-step explanation:
∵ S is the centroid of ΔNLM
∴ S divides NG at ratio 1 : 2 from the base
∴SQ = 1/2 NS
∴3x - 5 = 1/2 (4x)
∴3x - 5 = 2x
∴3x - 2x = 5
∴x = 5
∴ NS = 4 × 5 = 20 cm
100x 0.18 as it equals 18 when you multiply it
Let the balance = Y and the number of weeks = x
She takes out 15 per week, so multiply 15 by x ( the number of weeks) to get 15x.
You would then want to subtract that from the amount she started with in her account.
The equation becomes: Y = 150 - 15x
Answer:
270 ft^2
Step-by-step explanation:
find the area of each side
top: 13x7=91
triangle shaped sides(both together): 12x5=60
tiny vertical side: 7x5=35
bottom: 12x7=84
add them all together to get the total surface area is 270ft^2
Hope this helps! :)
