Answer: C) 6

================================================

Explanation:

2.33333... where the 3s go on forever is the same as 2 + 1/3 or 2 & 1/3

So we really have 3 & 2/3 added onto 2 & 1/3

The fractional portions add to 2/3 + 1/3 = 3/3 = 1, which will carry over.

The whole number portions add to 3+2 = 5, and we add on the carry of 1 to get 5+1 = 6

--------------

Using your calculator

3 & 2/3 = 3 + 2/3 = 3 + 0.667 = 3.667 approximately

adding this onto 2.333 leads to

3.667 + 2.333 = 6

Technically the 6's go on forever in the decimal form of 3 & 2/3, but rounding wont have an effect on the answer when we add

Find the missing y-coordinate that makes the two triangles congruent. Triangle ABC: A(8,4), B(2,6), C(5, 0) Triangle MNO: M(7,4)

Zolol [24]

Answer:

y = 8

Step-by-step explanation:

Two triangles are said to be congruent if all the three sides and three angles of both triangles are equal.

The distance between two points on the coordinate plane is given as:

$Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\$

In triangle ABC:

$|AB|=\sqrt{(2-8)^2+(6-4^2)}=\sqrt{40} =2\sqrt{10}\\\\|AC|=\sqrt{(5-8)^2+(0-4)^2}=5\\\\|BC|=\sqrt{(5-2)^2+(0-6)^2 }=\sqrt{45}$

In triangle MNO:

$|MN|=\sqrt{(1-7)^2+(2-4^2)}=\sqrt{40} =2\sqrt{10}\\\\|MO|=\sqrt{(4-7)^2+(y-4)^2}\\\\|NO|=\sqrt{(4-1)^2+(y-2)^2 }$

Since triangle ABC and triangle MNO are congruent, hence:

|AB| = |MN| = 2√10, |AC| = |MO| = 5, |BC| = |NO| = √45

$|AC|=|MO|=5\\\\\sqrt{(4-7)^2+(y-4)^2}=5\\\\(4-7)^2+(y-4)^2=25\\\\9 +(y-4)^2=25\\\\(y-4)^2=16\\\\square\ root\ of\ both\ sides:\\\\y-4=4\\\\y=4+4\\\\y=8$

Hence O = (4, 8)

What is the range of the data represented by the box plot? A. range = 2 B. range = 4 C. range = 10 D. range = 12

Natalija [7]

Answer:

The range is 12 answer (D)

Step-by-step explanation:

∵ The range = the largest value - the smallest value

∵ The largest value is 17

∵ The smallest value is 5

∴ The range = 17 - 5 = 12
