Answer:
125 cm^3
Step-by-step explanation:
Find THE volume of this cube of side length 5 cm:
Volume of a cube is V = s^3, where s is the side length.
Here, V = (5 cm)^3 = 125 cm^3
C. 65 degrees.
Triangles must equal 180 degrees. The given 50 means the rest of the triangle is equal to 130. I believe because of the Side-Angle-Side theorem of triangles (if my knowledge of proofs from 3 years ago is still with me), the two remaining angles are equal to each other. Let's call them X. 2x = 130. Divide both sides by 2. 130/2 = 65. So x=65
Answer:
(3x+7)(x+5) use stuff likephotomath math-way for this
Step-by-step explanation:
If 40% or .4 of her savings is $85 then we can write the equation .4s=$85 (s being the original amount in savings)
Divide both sides by .4 to get s= $212.50 as the original amount that she had
