Answer:

h = 3 cm

Step-by-step explanation:

The volume (V) of a rectangular prism is calculated as

V = Ah ( A is the area of the base and h the height )

Here V = 36 and A = 6 × 2 = 12 cm² , then

12h = 36 ( divide both sides by 12 )

h = 3

Answer: 3 cm

Step-by-step explanation:

The formula to solve the volume of a rectangular prism is V = l x w x h

Where V is volume, l is length, w is width, and h is height

Givens are, Volume = 36 cm3

length = 6 cm

width = 2 cm

Now, we will plug in the numbers to the formula

36 cm3 = 6cm x 2cm x h

36 cm3 = 12 cm2 x h

divide 12cm2 on both sides

36cm3/12cm3 = h

h = 3cm

In circle J with m \angle HJK= 50m∠HJK=50 and HJ=16HJ=16 units, find the length of arc HK. Round to the nearest hundredth.

Answers

Answer:

13.96

Step-by-step explanation:

length of an arc = theta/360 * 2πr

Given

m<HJK = 50

HJ = 16units

Required

length of arc HK

arc HK = 50/360 * 2(3.14)(16)

arc HK = 5/36 * 100.48

arc HK = 502.4/36

arcHK = 13.96

hence the length of arcHK to nearest hundredth is 13.96

Las longitudes de dos lados de un octágono regular están representadas por las expresiones 2x + 4 y 3x-8. Encuentra la longitud de un lado del octágono

Answers

Answer:

La longitud del lado del octágono es de 28 unidades.

Step-by-step explanation:

Si las longitudes de los dos lados pertenecen a un octágono regular, entonces se satisface la siguiente condición:

[tex]2\cdot x + 4 = 3\cdot x - 8[/tex] (1)

A continuación, despejamos [tex]x[/tex] en (1):

[tex]3\cdot x - 2\cdot x = 4 + 8[/tex]

[tex]x = 12[/tex]

Ahora, determinamos la longitud del lado del octágono: ([tex]x = 12[/tex])

[tex]l = 2\cdot x + 4[/tex]

[tex]l = 28[/tex]

La longitud del lado del octágono es de 28 unidades.

Which of the following functions has a line of symmetry of x = 2?

Step-by-step explanation:

To solve the equation 34x=15, Abby multiplied both sides by ¾ and got a solution of x=1114. Explain the error that Abby made and then find the correct value of x.

Answers

Answer:

x = 20

Step-by-step explanation:

3/4x = 15

Abby's calculation:

3/4x = 15

Multiply both sides by 3/4

x = 1114

Abby's error was multiplying both sides by 3/4 instead of dividing both sides by 3/4 to get the value of x

Correct calculation:

3/4x = 15

Divide both sides by 3/4

3/4x ÷ 3/4 = 15 ÷ 3/4

x = 15 × 4/3

x = 60/3

x = 20

Check:

3/4x = 15

3/4*20

= (3*20) / 4

= 60/4

= 15

3/4*20 = 15

The box plots show the data distributions for the number of customers who used a coupon each hour during a two-day sale.

Which measure of variability can be compared using the box plots?

interquartile range

standard deviation

mean

median

Answers

Answer:

Interquartile age

Step-by-step explanation:

The box plots that is being referred to are missing, however, we can still answer this without the box plots.

The appropriate measure of variability that can be easily determined by a box plot is the interquartile range. Which is the difference between the 3rd quartile and the 1st quartile.

On a box plot, the first quartile is the data value ta the beginning of the edge of the rectangular box while the third quartile is at the end of the edge of the rectangle box. So, this makes is easy for use interquartile range as a measure of variability when comparing both.

Answer:

Interquartile range (IQR)

explanation:

Mean and median are both measures of center so it can't be those two, and the standard deviation is a measure of variability but only when the graph, box plot or any other type of graph is symmetric
