for question 1
Area of Base B =45×25 = 1125 cm²
perimeter of base P = 2(45+25) = 140 cm
Height = 15 cm
Using the formula
Surface area = 2B + Ph
A = 2×1125 + 140×15= 4350 cm²
Voume = Bh = 1125×15= 16875 cm³
For question 2,
Area of base = 7× 5/2= 17.5 cm²
Perimeter of base = (7+7+7) = 21 cm
Surface area = 2B + Ph
Surface area of prism = 2×17.5+ 21×10 = 245cm²
Volume = Bh = 17.5×10 = 175 cm³
Answer:
3 weeks, $45
Step-by-step explanation:
So we can make an equation!
55+5x=100-10x
So solving for x,
X=3
1.To find the triangle area is base x height : 4.33 x 5=21.65
Perimeter : 5+5+5=15
2. 6•3=18+(3•2)=18+6=24=area
16=perimeter
3. Not sure
4. 12•17=204=area
Perimeter : 13+17+17=47
Hoped I helped!
The range would be [-4, infinity) because range is the y-value. The lowest y-value is -4. The greatest y-value goes up to infinity.
(25-y) ^2-y^2=25
y=12
x=25-12
x=13
(13,12)
