9:16 -> 3:8

How?

Divide each side by 2 (the GCF).

10:12 -> 5:6

How?

Divide each side by 2 (the GCF).

20:16 -> 5:4

How?

Divide each side by 4 (the GCF).

24:36 -> 2:3

How?

Divide each side by 12 (the GCF).

Answer:

9: 16 for 9 to 16; is the simplest form for 9/16 cuz nothing can go into 9 and 16

5 : 6 for 10 to 12; cuz 10 divided by 2 is 5 and 12 divided by 2 is 6!

5: 4 for 20 to 16; cuz 20 divded by 4 is 5 and 16 divded by 4 is 4

lastly is 2:3 for 24 to 36; why? well it's ciz 24 divided by 12 is 2 and 36 divedde by 12 is 3

hope this helps and pls don't delate my answer!

Answer:

Mick can run farther in less time if that's the question

Step-by-step explanation:

Mick's speed is faster.

Speed is the ratio of distance and time.

It shows how fast an object is moving at a given time.

We have,

Carlos can run 5 miles in 45 minutes.

45 minutes = 45/60 = 0.75 hours

Speed.

= 5/0.75

= 6.66 miles per hour.

Kelly can run 10 miles in 80 minutes.

80 minutes = 1.33 hours

Speed.

= 10/1.33

= 7.5 miles per hour.

Mick can run 30 miles in 170 minutes

170 minutes = 2.8 hours

Speed.

= 30/2.8

= 10.7 miles per hour

Thus,

Mick's speed is faster.

Answer:

The right answer is A

Step-by-step explanation:

The value of the exponential equation is y = 3ˣ and the graph is plotted

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

y = 3ˣ   be equation (1)

Now , the y intercept of the equation is when x = 0

So , when x = 0

y = 3⁰

y = 1

Now , when y₁ = 3^1.2

The value of y₁ = 3.7

Therefore , the y intercept of the equation is 1 and the graph is plotted

Hence , the exponential equation is y = 3ˣ

B) Smartphones

Step-by-step explanation:

In order to answer this question we need to find the total revenue for the laptops and smartphones.

Let's start with the laptops.

Given:

To find the total revenue of all these laptops we need to multiply 200 by 499.

[tex](200) *(499) = 99,800[/tex]

Therefore, the total revenue of the laptops alone is $99,800.

Now, let's do the smartphones.

Given:

To find the total revenue of all these smartphones we need to multiply 350 by 399.

[tex](350) * (399) = 139,650[/tex]

Therefore, the total revenue of the smartphones alone is $139,650.

Comparing the two revenues we see that the smartphones generate more sales in dollars.

Hope this helps!

no

Step-by-step explanation:

1. to make up the equations of lines PQ and RS:

(PQ)  [tex]\frac{x-0}{2} =\frac{y+9}{1}; \ \frac{x}{2}=\frac{y+9}{1};[/tex]

(RS)  [tex]\frac{x-1}{-2}=\frac{y-4}{1}; \ \frac{x-1}{-2}=\frac{y-4}{1};[/tex]

2. to write the pointed verctors of PQ and RS:

for PQ it is p=(2;1); for RS it is r=(-2;1).

3. according to the pointed vectors it is clear, the given lines are not perpendicular [2*(-2)+1*1≠0].

B: sometimes

Step-by-step explanation:

Let's look at two examples.

Example A.

2, 3, 5: mean is 3

Replace 5 with 1. Now you have 1, 2, 3: mean is 2.

In this case, it affected the mean.

Example B.

2, 3, 5: mean is 3

Replace 5 with 4. Now you have 2, 3, 4: mean is 3.

In this case, it did not affect the mean.

As you can see, replacing the maximum value of the data set with a smaller number may or may not change the mean.
