Answer:

75°C = 5h

Step-by-step explanation :

1. Make sure your mind is fresh and that you understand each step before reading

2. 24 hours is equal to 360°C

3. so now lets break up the hours. We can do this by choosing a simple degree that was given in the diagram. For example "Watching tv".

Tip : when choosing one of the degrees , ( i mean one of the choices like watching tv, playing and sleeping) , try choosing the simplest one , which has a simple number and a multiple of 360.

so now you want to know how many hours is 60 equal to .

= 360 ÷ 60 = 60 (this is to make sure the number is a multiple and will not be a decimal )

= 24 ÷ 6 = 4

this means Ali spend 4 hours watching tv

and by doubling that you get 60°C = 4h

the amount of time he slept 120°C = 8h

and you keep playing with the numbers like that

so for playing

60°C = 4h

divide by 4 15°C = 1h

× by 5 75°C = 5h

this means ali spends 5h playing , 8h sleeping, 4h watching tv and 7 h studding

Thea has a key on her calculator marked $\textcolor{blue}{\bf\circledast}$. If an integer is displayed, pressing the $\textcolor

mel-nik [20]

Answer:

$9$

Step-by-step explanation:

Given: Thea enters a positive integer into her calculator, then squares it, then presses the $\textcolor{blue}{\bf\circledast}$ key, then squares the result, then presses the $\textcolor{blue}{\bf\circledast}$ key again such that the calculator displays final number as $243$.

To find: number that Thea originally entered

Solution:

The final number is $243$.

As previously the $\textcolor{blue}{\bf\circledast}$ key was pressed,

the number before $243$ must be $324$.

As previously the number was squared, so the number before $324$ must be $18$.

As previously the $\textcolor{blue}{\bf\circledast}$ key was pressed,

the number before $18$ must be $81$

As previously the number was squared, so the number before $81$ must be $9$.

Find the new price after the markdown given. Round to the nearest cent if necessary. $5,250 marked down 15%

PIT_PIT [208]

Marked down 15% means the new price would be 85% of the original price ( 100%-15% - 85%)

Multiply the original price by 85%:

5250 x 0.85 = 4462.50

The new price is $4,462.50

r $\leq$ 15.5 (not the one with the line under it i just couldnt find the one that didnt have the line under it)

for the graph, put 16 on the right side and label the lines right to left 16 15.5 14 14.5 etc. Put an open circle on the 15.5 line. then make an arrow pointing to the left.

10:

80 $\leq$ p+64

This is because she needs 80 points OR MORE and (p represents the points) she already has 64. She needs 80 to be less than or equal to the amount of points earned.

The solution is 16 $\leq$ p because 80-64=16 and p is needs to be greater than or equal to 16
