Step-by-step explanation:

Option D is the correct answer

Because if the blouse is of 8 dollars then 4 blouses = 32 and skirt = 12 so 3 skirts = 36

36 + 32 = 68

Susan bought 6 blouses = 8 x 6 = 48

3 skirts = 12 x 3 = 36

48 + 36 = 84

In this rectangular box, EF = 16, FD = 5, and DB = 30. Find AF.
AVprozaik [17]

Answer:

FA = 25.87  

Step-by-step explanation:

Given: BD = 30 , DF = 5 , EF = 16

To find: FA

Rectangular box is a Cuboid.

Figure attached.

AB = FE = 16

So,

In  ΔADB

using Pythagoras theorem,

DB^2=AB^2+AD^2\\30^2=16^2+AD^2\\900=256+AD^2\\AD^2=900-256\\AD^2=644\\AD=\sqrt{644}\\AD=2\sqrt{161}

Again using Pythagoras theorem in Δ ADF we get

FA^2=DF^2+AD^2\\FA^2=5^2+(2\sqrt{161})^2\\FA^2=25+644\\FA^2=669\\FA=\sqrt{669}\\FA=25.87

Therefore, FA = 25.87

FrozenT [24]

Answer:

first blank: mean

second blank: greater than

third blank: increased

fourth blank:  greater than

Step-by-step explanation:

I can't see the options in each blank, even though I completed them with reasonable options.

The MAD of a set of data is the average distance between each data value and the mean. 400 is further than the mean than the MAD. This, increases the variability of the originally data set. As a consequence, the inclusion of 400 will result in a greater MAD

Jillian’s school is selling tickets for a play. The tickets cost $10.50 for adults and $3.75 for students. The ticket sales for
sergij07 [2.7K]

Answer:

The number of adults tickets sold   = 168.

Step-by-step explanation:

The cost of 1 adult ticket  = $10.50

The cost of 1 student ticket =  $3.75

The total sales from the ticket = $2071.50

Now, here let us assume

The number of adult tickets sold  = a

The number of student tickets sold  = b

So, the equation is given as :

10.50 a + 3.75 b = 2071.50

Now, its given the number of students  = 82

⇒ <u>b  =  82</u>

Putting the value of b in the above equation,w e get:

10.50 a + 3.75 ( 82) =  2071. 50

or, 10.50 a  = 2071.50 - 307.5 =  1764

or, a = 1764/10.5 =  168

Hence, the number of adults tickets sold  = a = 168.
