A pair of vertical angles has measures (3x+4)° and (7x-9)°<br> What is the value of x?

Andrei [34K]

Since they are vertical they are equal to each other.

3x + 4 = 7x - 9
4 = 4x - 9
13 = 4x
3.25 = x

So the value of x is 3.25.

Hope this helps :)

A media company wants to track the results of his new marketing plan so the video production manager recorded the number of use

Answer:

$f(x)=5120(5)^{x}$

Step-by-step explanation:

From the image, f(x) and x are rlated by

$f(x)=a( {b})^{x}$

where b is the common ratio

We first find the value for b

$\frac{6400}{5120}= 5$

$\frac{8000}{6400}= 5$

$\frac{10000}{8000} = 5$

$\frac{12500}{10000} = 5$

$\frac{15625}{12500}=5$

so we can say the common ratio, b=5

we put in any value of f(x) and the corresponding value for x to find a value

Let put x=0 and f(x)=5120

This implies that

$5120 = a(5)^{0}$

but

$5^{0} = 1$

Hence a=5120

Thus the equation which model the relationship between the weeks and the viewers is

$f(x)=5120(5)^{x}$

72 = 6*12 = 3*2 * 4*3 = 3*2*2*2*3

72 = 2*2*2*3*3

72=2^3 * 3^2

You can check your answer by multiplying out the factors

2*2*2*3*3

2*2 is 4

4*2 is 8

8*3 is 24

24*3 is 72

How many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water?

RoseWind [281]

Answer:

The number of 1/5 liter glasses that Lin can fill is $7\frac{1}{2}$

Step-by-step explanation:

we know that

To find out how many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water, divided 1 1/2 by 1/5

$1\frac{1}{2} :\frac{1}{5}$

Convert mixed number to an improper fraction

$1\frac{1}{2}=1+\frac{1}{2}=1\frac{1*2+1}{2}=\frac{3}{2}$

substitute

$\frac{3}{2} :\frac{1}{5}$

Multiply in cross

$\frac{5*3}{2*1}=\frac{15}{2}=7.5$

Convert to mixed number

$7.5=7+\frac{1}{2}=7\frac{1}{2}$
