Answer:

Option D is the Answer

Step-by-step explanation:

Given : Benni wants to divide 48.6 by 0.7.

To find : In order to estimate the quotient, which is the best expression to use?

Solution :

In order to estimate i.e. an approximate calculation we round the numbers,

48.6 as tenth place is > 5 then it round completely

0.7 as tenth place is > 5 then it round completely

So the estimated expression is given by,

Therefore, option D is correct.

Answer: D

To estimate, McKenna would need to round both numbers to the nearest whole number, which give 48.6 rounded to the nearest whole number is 50. 0.7 rounded to the nearest whole number is 1.

Inessa [10]

Answer:

solution given:

similar cylinders ratio 1:3

let the ratio be 1x and 3x respectively:

according to the question:

x/3x=volume of (smaller cylinder/big cylinder)

Volume of big Cylinder=67cm³×3=201cm3

201cm³ is your answer

Answer:

Part A none

Part B drawn

Step-by-step explanation:

Suppose the transversal intersects a pair of parallel lines it creates two pairs of alternate exterior angles.

Now if we look at the first figure we find that the alternate exterior angle 1 and 4 are equal . Also 3 and 2 are equal.

But <1 and < 2 are not equal . They are supplementary angles. Their sum is equal to 180 degrees.

Similarly angles 3 and4 are supplementary angles.

This situation does not support Ricky's claim. So you will select none in part A.

Now in part B we see that angle 5 &8 are equal and 6 & 7 are congruent.

This refutes Ricky's claims and this can be proved mathematically.

Angles 5 & 6 are supplementary angles. Similarly 7 & 8 are supplementary therefore they cannot be equal as they are unequal and a transversal is drawn not a perpendicular.
