Answer:

B. a rectangle

Step-by-step explanation:

When a figure is sliced along a given or required plane, the cross section of the sliced surface produces another figure or shape.

In the question, the figure has a triangular base. So that, the cross section along the required plane would give a rectangular shape. This is because the cross section is perpendicular to the triangular base, and passes through a vertex of the base.

By appropriate procedures and the given conditions, the shape of the cross section would be a rectangle.

Which of the following numbers in the data set is an outlier? 21, 23, 19, 25, 83, 23, 21
postnew [5]

The outlier in this set of data is 83.

The outlier in a data set is any number that is <em>much </em>higher or lower than the average of the set.

83 is nowhere near the average of 23 in this set, and so it is the sole outlier.

Hope this helps!

What is x over 2+ 4&lt;7
N76 [4]
 x/2 + 4 < 7

multiply both sides by 2
x/2 * 2 + 4 * 2 < 7 * 2
which equals
x + 8 < 14
subtract 8 from both sides
x + 8 - 8 < 14 - 8
x < 6

Eureka Math : 5 ÷ 1/3= ____. There are ___ thirds in 1 whole. There are ___ thirds in 5 wholes. If 5 is 1/3, what is the whole?
oksian1 [2.3K]

Let me edit your question to simplify it.

Eureka Math :

A)5 ÷ 1/3= ____.

B) There are ___ thirds in 1 whole.

C) There are ___ thirds in 5 wholes.

D) If 5 of 1/3, what is the whole? ___

E) 3 ÷1/5= ____ .

F) There are ___ fifths in 1 whole.

G) There are ___ fifths in 3 wholes.

H) If 3 of 1/5, what is the whole?___

Answer:

A) 15

B) three thirds

C) 15 wholes

D) whole is 2

E) 15

F) five fifths

G) 15 fifths

H) whole is 1

Step-by-step explanation:

A)

  • 5÷\frac{1}{3} =5*\frac{3}{1}
  • 5÷\frac{1}{3}=15

<u>Third:</u>

  • third means \frac{1}{3}<u> </u>

B)

  • To make 1 whole from thirds, we need three thirds i.e. \frac{1}{3}+\frac{1}{3}+\frac{1}{3}=\frac{3}{3}=1\ Whole

C)

  • In 1 whole there are three thirds, so in 5 wholes there are 5*3=15 wholes.

D)

  • In 5\ of\ \frac{1}{3}=5*\frac{1}{3} =\frac{5}{3}
  • \frac{5}{3}=1.6
  • The whole of 1.6 or \frac{5}{3} is 2 (rounding 1.6 to 2)

E)

  • 3÷\frac{1}{5}=3*5=15

<u>Fifth:</u> means \frac{1}{5}

F)

  • To make 1 whole of fifths we need five fifths i.e. \frac{1}{5} +\frac{1}{5} +\frac{1}{5} +\frac{1}{5} +\frac{1}{5}=\frac{1+1+1+1+1}{5}=\frac{5}{5}=1

G)

  • In 1 whole we have 5 fifths, so in 3 wholes we have 3*5=15 fifths

H)

  • 3\ of\ \frac{1}{5}=3*\frac{1}{5}=\frac{3}{5}=0.6
  • rounding 0.6 equals to 1
  • thus whole is 1.

Five brothers wanted to share a parcel of land inherited for their late father. The first born received ¼ of the parcel. The sec
Dmitry [639]

Step-by-step explanation:

Let the size of their father's land be x.

The first born received x/4

The second, third and fourth born each received 1/6 * (x - x/4) = 3x/24 = x/8

The portion received by the last born = x - (x/4 + 3*x/8) = x - (x/4 + 3x/8) = x - (5x/8) = 3x/8

3x/8 = 3hectares

3x = 24

x = 8.

. : The initial size of the parcel land was 8 hectares.
