Answer:
Step-by-step explanation:
first we need to calculate the area of isosceles triangle having sides 48cm, 48cm and 30cm
a = 48
b= 30
Area of isosceles triangle using only sides = ½[√(a^2 − b^2 /4) × b]
= 1/2*30√( 48² - 1/4×30²)
=1/2*30√ (2304 -225)
=684sq cm
cost required to make umbrella= 10*684*5
= 3<em>4200</em>
Answer:
V = 26d^2 + 624d
Step-by-step explanation:
Volume = Width x Depth x Height
V = 26 (d) (d+24)
Now distribute 26
V = 26d(d+24)
Then distribute 26d
V = 26d^2 + 624d
Answer:
Alana is 13 years old.
Step-by-step explanation:
Assuming you meant Mazo = Maisel,
You start from the bottom:
Amelia is 10 years younger than 17-year-old Maisel.
Amelia is 7 years old. (17-10)
Ernie is 2 years older than 7-year-old Amelia.
Ernie is 9. (2+7)
Alana is 4 years older than 9-year-old Ernie.
Alana is 13 years old. (4+9)
Hope this helps!
