Answer:

217.2

Step-by-step explanation:

You divide the two numbers. The tenths place is the number after the decimal. The answer without rounding is 217.19(other numbers). 9 raises 1 up to 2 so that's why the answer is 217.2.

Answer: the answer should be the last one

Step-by-step explanation:

One angle be x

ATQ

[tex]\\ \sf\longmapsto x+2x-6=90[/tex]

[tex]\\ \sf\longmapsto 3x-6=90[/tex]

[tex]\\ \sf\longmapsto 3x=96[/tex]

[tex]\\ \sf\longmapsto x=32[/tex]

[tex]\\ \sf\longmapsto 2x-6=2(32)-6=58°[/tex]

Answer:

58°

Step-by-step explanation:

The measure if one 2 complementary angle is 6 less than the measure of the other => x + 2x - 6° = 90°

x + 2x - 6° = 90°

3x = 90° + 6°

3x = 96°

x = 96° : 3

x = 32°

Substitution :

2x - 6°

= 2 × 32° - 6°

= 64° - 6°

= 58°

Answer:

The student should subtract 8 from each side not add 8

Step-by-step explanation:

Point slope form is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line

y - -8 = -6(x -2)

y+8 = -6(x-2)

Distribute

y+8 = -6x+12

Subtract 8 from each side

y+8-8 = -6x+12-8

y = -6x+4

The student should subtract 8 from each side not add 8

Answer:

y -(-8) = -6(x - 2)

y -(-8) = -6x + 12

y -(-8) + 8 = -6x + 12 + 8 (this step is incorrect as minus into minus is plus therefore when taking 8 to the right hand side we must subtract it from the left hand side

y = -6x + 20

the correct equation would be : y= -6x+4

Answer: 11.9 and 12.5

Step-by-step explanation:

|x - 12.2| = 0.3 is telling us that x must be either 12.2 + 0.3 or 12.2 - 0.3.

Longest is (12.2 + 0.3) = 12.5

Shortest is (12.2 - 0.3) =  11.9

Answer:

7,600

Step-by-step explanation:

both parents invest 7,600.

7,600x2= 15,200

there are 2 girls so divide 15,200 by 2 and u get 7,600

Answer:

−128

Step-by-step explanation:

Assuming the pattern continues...

Answer:

[tex]128[/tex]

Step-by-step explanation:

We see that this is a geometric series with common ratio [tex]-2[/tex].

So, the 6th term is the 4th term times [tex](-2)^2=2^2=4[/tex].

So, the answer is [tex]4(-32)=\boxed{128}[/tex] and we're done!

Note:

The closed form for this geometric series is [tex]4*(-2)^{n-1}[/tex], which means the nth term is always [tex]4*(-2)^{n-1}[/tex].

Answer:

20

Step-by-step explanation:

[tex] \sqrt{(( - 10) - 9)^{2} + (12 - ( - 3)) ^{2} } [/tex]

[tex] \sqrt{( - 19)^{2} + (15)^{2} } [/tex]

[tex] \sqrt{361 + 225} [/tex]

[tex] \sqrt{586} [/tex]

[tex]24.2074[/tex]

Step-by-step explanation:

Okay so, 22:40 is 10:40pm

07:32 is am

Time goes up to 60 minutes, it would be 52 minutes at the end(20m to get to 11pm + the 32minutes)

Then there would be 8 hours alone (11 to 7 is 8 hours)

So it takes 8 hours and 52 minutes from 10:40pm to 7:32am

Answer:

-3x + 8 ≥ 35, hopefully that answers your question since you didn't really specify what you wanted your answer to be

Answer: 32

Step-by-step explanation: since Jiri is 9 years older, you set an equation where x (Pamelia age) + 9. So the equation is 55= x + (x+9). You subtract 9 from both sides, then divide 46 by 2 to find the Pamelia age. To find Jiri’s age, add 9 to 23 (Pamelia age).

Answer:

-1/2, +1/4, -1/8, +1/16, -1/32, +1/64

Step-by-step explanation:

multiplying a negative by a negative makes it a positive. Multiplying a positive by a negative makes it a negative. The order will be negative, positive, negative, positive, negative, positive, etc.

Answer:

Step-by-step explanation:

5¹⁶ ÷ 5² = 5⁽¹⁶ ⁻ ²⁾ = 5¹⁴  ❌

(5²)⁶ ÷ 5⁴ = 5⁽¹² ⁻⁴⁾ = 5⁸ ✅

5² × 5⁴ = 5⁽²⁺⁴⁾ = 5⁶ ❌

(5⁴)² = 5⁸ ✅

5⁻¹ × 5⁹ = 5⁻¹ ⁺ ⁹ = 5⁸ ✅

5⁻¹ × 5⁻⁸ = 5⁻¹ ⁺ ⁽⁻⁸⁾ = 5⁻⁹ ❌

I am pretty sur it is 3

Step-by-step explanation:

Answer:

3f

Step-by-step explanation:

The expression given is f + f + f.

f + f + f = f × 3

The correct way to write an expression that is being multiplied is to put the number before it with no symbols or spaces in between them:

f + f + f =

f × 3 =

3f
