Answer:
0.082 = 8.2% in decimal form
50 * 0.082 = <u><em>4.1</em></u>
<u><em>8.2% of 50 is 4.1</em></u>
Answer:
Base = 126 cm or 60 cm
Step-by-step explanation:
Ratio of sides of isosceles triangle = 4 : 7
Sides are = 4x , 7x
If smallest sides of the isosceles triangle are equal, then
three sides are = 4x , 4x , 7x
Perimeter = 270 cm
4x + 4x + 7x = 270
15x = 270
x = 270/15
x = 18
Base = 7x = 7*18 = 126 cm
If largest sides of the isosceles triangle are equal, then
Three sides are = 7x , 7x , 4x
7x + 7x +4x = 270
18x = 270
x = 270/18
x = 15
Base = 4x = 4 * 15 = 60 cm
The width is 8 and the length is 25
(8*2)+2[9+2(8)]
=16+2(9+16)
=16+2*25
=16+50

Answer:Volume of Rock= 97.5ml
Step-by-step explanation:
STEP 1
Finding the volume of rock using the graduated cylinder that measures volume of liquid can be done by determining how much water is being displaced by the rock after submersion.
Step 2
Volume of water before adding rock = 200mL
Volume of water after adding the rock = 297.5mL
Volume of rock =Volume of water after adding the rock - Volume of water before adding rock
Volume of Rock = 297.5-ml 200ml
= 97.5ml
Answer:
2(8 x 4) + 2(4 x 10) + 2(8 x 10)
Step-by-step explanation:
the expression represents the surface area, because it is finding the area of the three different sizes of sides, doubling them, then adding them together
