The laptop screen turns off when the angle between the keyboard and the screen is less than 20°. How many more degrees can the laptop screen close before the screen turns off?

The laptop screen can close ?° more before the screen turns off

Add the two angles and then subtract from 180* to find the missing angle

So,

145* + 15* = 160*

180* - 160* = 20*

Answer: x = 20*

Answer:

x = 1

y = 2

Step-by-step explanation:

for the first one it is that because 4 * 1 = 4 and then 2 * 2 equals 4 so 4 + 4 = 8

For the second one it is that because 8 * 1 = 8 and then 4 * 2 = 8 so 8 + 8 = 16!

Answer:

[tex]\frac{1}{10}*\frac{3}{4} =\frac{3}{40}[/tex]

Step-by-step explanation:

There are 10 numbers 0,1,…9

Probability that 3 is selected is  [tex]\frac{1}{10}[/tex]

Again, there are 4 letters A,B,C & D of which 3 are consonants and 1 is vowel. So, probability of selecting a consonant is [tex]\frac{3}{4}[/tex] . Hence, the required probability is [tex]\frac{1}{10} *\frac{3}{4} = \frac{3}{40}[/tex]

Answer: x=4 and y=1

Step-by-step explanation:

From the first equation, we get y = 9 - 2x. Substitute this into the second equation we get

3x - 4(9 - 2x) = 8

3x - 36 + 8x = 8

11x = 44

x = 4

y = 9 - 2(4)

y = 1

Answer:

$9.05

Step-by-step explanation:

We need to find 20% of 45.26

20% = 20/100 = 1/5 = 0.2

Of is related to multiplication

So, 20% OF 45.25 is 0.2 times 45.26

0.2 * 45.26 = 9.052

9.052 needs to be rounded to 9.05

The answer is $9.05

Hope this helps :)

Have a great day!

Answer:

g(0) = 0

g(1) = 1  

g(-1) = 1  

Step-by-step explanation:

g(1) = -1 means that when 1 is inputted into the function, the output is -1.

Therefore, y = -1 when x = 1.  From inspection of the graph, when x = 1, y = 1, therefore this is untrue.

g(0) = 0 ⇒ y = 0 when x = 0. From inspection of the graph, when x = 0, y = 0. Therefore this is true.

g(4) = -2  ⇒ y = -2 when x = 4. From inspection of the graph, we cannot read when x = 4, but y > 0 when x = 4.  Therefore this is untrue.

g(1) = 1  ⇒ y = 1 when x = 1. From inspection of the graph, when x = 1, y = 1. Therefore this is true.

g(-1) = 1  ⇒ y = 1 when x = -1. From inspection of the graph, when x = -1, y = 1. Therefore this is true.

Answer: The answer is x=3

Step-by-step explanation:

Let's solve your equation step-by-step.

5x−4=11

Step 1: Add 4 to both sides.

5x−4+4=11+4

5x=15

Step 2: Divide both sides by 5.

Answer:

x=6, y=3

Step-by-step explanation:

6x +2y=42------(1)

8x-4y=36-------(2)

We can actually simplify it, this makes it easier to do and can avoid alot of careless mistakes

3x+y=21---(1)

2x-y=9----(2)

next, we can see that y can be eliminated

(1)+(2),

5x=21 +9

x = 30/5

x=6

substitute x=6 into (2),

2(6)-y=9

y=3

Lastly ,make a conclusion

Thus, x=6, y= 3

[tex] 6x + 2y = 42 \\ 8x - 4y = 36[/tex]

Simplify the first equation

[tex]y = 18 \\ 8x - 4y = 36[/tex]

Multiply both sides of second equation by 1/4

[tex]y = 18 \\ 2x - y = 9[/tex]

Sum the equations vertically to eliminate at least one variable

[tex]x = \frac{27}{2} [/tex]

The possible solution of the system is the ordered pair (x,y)

[tex] (x,y) = ( \frac{27}{8} , 18)[/tex]

Step-by-step explanation:

i) Since,

Diagonals of a parallelogram bisect each other so,

RM = 2 × RP

=> RM = 2 × 12

=> RM = 24 (Ans)(i)

ii) Since,

Opposite sides of a parallelogram are equal so,

GM = AR = 15

=> GM = 15 (Ans)(ii)

iii) Since,

Opposite sides of a parallelogram are equal so,

AM = RG = 19

=> AM = 19 (Ans)(iii)

Given :

GRAM is a parallelogram where

Solution :

We know that,

So,

RG = 19

⇢ RG = AM [Opposite sides]

⇢ AM = 19 .

Since,

⠀⠀RP = 12

⇢ RM = 2(RP) [Diagonals bisect each other]

⇢ RM = 2(12)

⇢ RM = 24

Since,

⠀⠀AR = 19

⇢ AR = GM [Opposite sides]

⇢ GM = 15 .

Answer:

15.65 foot

Step-by-step explanation:

Pythagoras theorem can be used

a² + b² = c²

a being 14
b being unknown ( x )
c being 21

hence,

14² + x² = 21²
196 + x² = 441

x = √245  

  = 15.65 foot (answer)

Answer:

It is a linear function because there is a constant rate of change in both the input and output values

Step-by-step explanation:

To determine if the function is linear, calculate the differences between the y values.

If the differences are constant, or the same value, the equation is linear and has a constant slope. If the differences are not the same, the equation is not linear.

difference between y values (output)

7 - 4 = 3

3 - 1 = 3

1 - -2 = 3

⇒ the function is linear

difference between x values (input)

-2 - -5 = 3

-5 - -8 = 3

-8 - -11 = 3

⇒ the function is linear as there is a constant rate of change in both the input and output values

Game 2

Step-by-step explanation:

Each hit the points would double (point(x2))

Example:

1x2=2, 2x2=4, 4x2=8, 8x2= 16, 16x2=32, and so on.

Answer:

It Depends

Step-by-step explanation:

Sample Answer: For up to 11 hits, Game 1 gives the player higher scores. But for 12 or more hits, Game 2 does. That's because exponential growth eventually exceeds linear growth.

Answer:

48 tons of steel per year

Step-by-step explanation:

you can make it a ratio problem but you can also divide it

144 tons : 3 years

? : 1 year

take 144/3 and you get

48 tons

so

48 tons : 1 year

Answer:

Unit rate= 36

Step-by-step explanation:

Divide 144 by 4 and you get 36. So, the steel company made 36 tons of steel in 1 year and made 144 tons of steel in 4 years
