First, we calculate the area of one paver. This is:
12 x 12 = 144 square feet
Now, the number of pavers required may be determined by dividing the total surface area to be covered by the surface area of one paver, as:
number of pavers = 600 / 144
Number of pavers = 4.2
Because 0.2 pavers can not be obtained, 5 pavers are needed to completely cover 600 square feet.
Answer: B
Step-by-step explanation: Always B
Answer:
B, because the equation of kinetic energy is = mv²
234 divided by 24 =9.75
390 divided by 40 = 9.75
9.75x 10 = 97.50
Part 1:
Given that triangle EFG is similar to triangle LMN, this means that the ratio of the measures of any two sides of triangle EFG is equal to the ratio of the measures of the corresponding sides of triangle LMN.
From the figure shown
FG / EG = MN / LN
⇒ 4 / 7 = 2 / LN
⇒ LN = 7 * 2 / 4 = 14 / 4 = 3.5
Therefore, LN = 3.5
Part 2:
<span>Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.
Thus, </span>if<span> m∠A = m∠D. The other fact that would guarantee that the triangles are similar is that m∠C = m∠F.
This is because if </span><span>m∠A = m∠D and </span><span>m∠C = m∠F, then </span><span><span>m∠B = m∠E and thus satisfies the triangle similarity condition.
</span>Part 3:
</span><span>Given
that the two triangles shown are congruent, one way to verify
that the corresponding angles of the two triangles are congruent is to place one of the triangle on top of the other to see if the corresponding angles of both triangles coincide.
This can be achieved by translating triangle 2 up by 2 units, and to the left by 6 units.
Part 4:
Given that t</span><span>rapezoid ABCD and trapezoid JKLM are similar.
From the naming of the trapezoids, the order of the naming of any similar object corresponds to the order of their similarity.
Thus, side AB corresponds to side JK, side AC corresponds to side JL and so on.
Therefore, the side that corresponds to side AB is side JK.</span>
