Which of the following is the correct way to express 320 in scientific notation?
A. 3.2 x 10²
B. 32.0 x 10²
C. 3.2 x 10³
D. 0.32 x 10²

Answer:Complementary angles are two angles whose sum is 90 degrees.

Let x represent one of the angles.

The other angle which is 84.2 degrees less would be x - 84.2.

Using this, we can write an equation.

x + (x-84.2) = 90.

Combine like terms:   2x - 84.2 = 90

Add 84.2 to both sides of the equation.

2x = 174.2

Divide by 2:  x = 87.1  

and x - 84.2 would equal 2.9.       to check: does  87.1 + 2.9 = 90?  yes.

Answer:

Step-by-step explanation:

The relation S is note a function when

2 - |k+1| = -6

Because when they are equal we have two points (-6,4) and (-6,7) in S which implies that -6 is related to two different values.

Now solving

2 - |k+1| = 6

2 - |k+1| = 6

2 - 6 = |k+1|

-4 = |k +1|

But absolute value always non negative, so there is no such k.

The yintercept is (0,0)

The reason why is because that is the place that intersects the y axis.

Answer:

2^3 .3^2

Step-by-step explanation:

if 2×2×2 = 8

and 3×3=9 then 8×9=72

Answer:

2³ × 3²

Step-by-step explanation:

Repeatedly divide by 2 until finish, then divide by 3

72 ÷ 2 = 36

36 ÷ 2 = 18

18 ÷ 2 = 9 , then

9 ÷ 3 = 3

3 ÷ 3 = 1 ← finish when 1 is reached

Then

72 = 2 × 2 × 2 × 3 × 3 = 2³ × 3²

Answer:

5

Step-by-step explanation:

25 = 5 x 5

45 = 5 x 9

Hey there!

25: 1, 5, & 25

because: 5 * 5 = 25 & 1 * 25 = 25

45: 1, 3, 5, 9, 15, 45

because: 1 * 45 = 45, 3 * 15 = 45, & 5 * 9 = 45

Common factors: 1 & 5

The bigger number of those two is 5

Therefore, your possible answer is: 5

Step-by-step explanation:

Let the number of students be x,

Now,

7% of x = 1400

or, 7/100 X x = 1400

or, x = 1400 x 100

—————

7

or, x = 140000/ 7

or, x = 20000

Thus, there are 20,000 students

Unfortunately there's not much we can say other than

[tex]\text{distance} = \sqrt{ (x_1-x_2)^2+(y_1-y_2)^2}\\\\\text{distance} = \sqrt{ (a-c)^2+(b-d)^2}\\\\[/tex]

If we knew the numbers that replace a,b,c,d, then we could compute the actual numeric distance.

Hey there!

Answer:

Step-by-step explanation:

1) 2x + 246 = 360° (Vertically opposite and angle at a point)

2x = 360 - 246

2x = 114°

x = 114 / 2

x = 57°

3) Since <ABD is a right angle (i.e its sum is 90°)

<CBD = 90° - 75° = 15°

5) <1 = <2 (Vertically opposite angles are equal)

12x + 3 = 10x + 15

12x - 10x = 15 - 3

2x = 12

x = 6

Therefore,

<2 = 10(6) + 15

<2 = 75°

Answer:

(4, 14) is on the given line

Step-by-step explanation:

We can use the points given in the answer choices to see if the point is on the line. If both sides are equal, then it is.

Option 1:

16 = 4(4) - 2

16 = 16 - 2

16 = 14

FALSE

Option 2:

13 = 4(4) - 2

13 = 16 - 2

13 = 14

FALSE

Option 3:

14 = 4(4) - 2

14 = 16 - 2

14 = 14

TRUE

Option 4:

10 = 4(4) - 2

10 = 16 - 2

10 = 14

FALSE

Answer:

5.9

Step-by-step explanation:

Did you mean rounding?

8 is in the tens place, and 9 is in the hundreds place. If the number in the hundreds place is greater than the number in the tens place, the tens place moves up by 1.

So 5.89 becomes 5.9

The probability that a student will be picked from a AP statistics class is 0.06

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. Probability can range from 0 to 1, where 0 means the event to be an impossible one and 1 is certainty

Probability = sample space / total possible outcome

the total possible outcome is 450 students

the number of students that take AP statistics alone = 39- 12= 27students

therefore probability of choosing from AP statistics= 27/450= 0.06
