We know that formular for volume of pyramid=area of base ×height
the area of the base is 1/2×base×height
=1/2×15×14
=105cm²
the given volume is 270cm³
∴height=volume÷base area
=270cm³÷105cm²
=

=
They just added 100 each time so i think the answer is b

Answer:
768 square inches
Step-by-step explanation:
Area of the rectangle = length × width
Length = 75 in
Width = 12 in
Area of the rectangle = length × width
= 75 in x 8 in
= 600 in²
Area of the square = length ²
Length = 12 in
Area of the square = length ²
= 12 in²
= 12 in × 12 in
= 144 in²
Area of a triangle = 1/2bh
b = base = 12 in
h = height = 4 in
Area of a triangle = 1/2bh
= 1/2 * 12 in * 4 in
= (1*12*4)in² / 2
= 48 in² / 2
= 24 in²
Total area of the painted part of the street sign = Area of the rectangle + Area of the square + Area of a triangle
= 600 in² + 144 in² + 24 in²
= 768 in²
Answer:
4x = 44 which is Carolyn's share.
Step-by-step explanation:
Equation
Use a variable to find out how the sum of the ratios would be divided up to make 77 dollars.
4x + 2x + x = 77 Combine like terms on the left
Solution
7x = 77 Divide by 7
7x/7 = 77/7 Do the division
x = 11
Answer
4*11 = 44 which is Carolyn's share
2*11 = 22 which is Julia's Share
1*11 = 11 which is Roberta's share.
