Step-by-step explanation:

6/7  / 3/5   we invert the divisor and multiply:

= 6/7 * 5/3

Answer:

it is 6...................

Answer:

the answer is D.

Step-by-step explanation:

well, the y-intercept for f(x) is at  

as you can see from the slope-intercept form is at 4, and it has an slope of 2/3.

for g(x), well an y-intercept is when x = 0, what is it from that table?  well, is at 0,3, so when x = 0, y = 3, so no dice on that one.

c)

whenever an x-intercept occurs, y = 0, for f(x) that's at  

what about the x-intercept for g(x)?  well, let's check, when is y = 0?  aha!  at -9, 0, so when y = 0, x = -9, so no dice on that one either.

d)

well, what is the slope of g(x) anyway?  well, let's pick two points off the table to get it hmmm the first two let's use,

and from a), using the slope-intercept form, we know f(x) has a slope of 2/3.

well, 2/3 is larger than 1/3, so no dice.

b)

well, you already know.

Answer:

The constant of proportionality between 'y' and 'x' in the graph is 0.75

Step-by-step explanation:

The constant of proportionality is the constant ratio between two quantities that are directly proportional.

When two quantities are directly proportional, then a percentage increase in one of the quantities will result in an equal percentage increase in the other quantity, and the two quantities are therefore, increasing at the same rate to each other

From the graph we have;

When x = 0, y = 0, all graphs of directly proportional relationships have  x = 0 when y = 0

However;

When x = 2, y = 1.5

When there is an 100% increase, we have;

When x = 2 + 100/100 ×2 = 4, y = 1.5 + + 100/100 ×1.5 =3

Therefore, when x = 4, y = 3

The constant of proportionality = The ratio between each 'y' and 'x' value

∴ The constant of proportionality = y/x = 1.5/2 = 3/4 = 0.75

Therefore;

The constant of proportionality between 'y' and 'x' in the graph = 0.75.

70.. not pretty sure tho

Answer:

B: 170

Step-by-step explanation:

Answer:  <1 = 105° and <2 = 75°

Step-by-step explanation:

The information we have is the 75 degree angle already provided. Using our knowledge on transverses we know a 180 degree angle is a straight line (we happen to have two of these (c and d)). Using the corresponding angle theorem we know angle 2 is equivalent to 75 degrees. Supplementary angles refer to angles that add up to 180 degrees. Angle 1 and 2 are supplementary so from there we solve.

180 - 75 = 105

<1 = 105 degrees

G. $7.75 per hour

Step-by-step explanation:

You can choose any of the three functions and divide the amount of pay by the hours worked, for example,

15.50/2=7.75

or

31/4=7.75

or

46.50/6=7.75

They're all the same rate so it doesn't really matter.

Answer:

y= 69x + 356

Step-by-step explanation:

y= 69x + 356

It goes 69 feet per second hence the 69x and it starts 356 feet in the air

The height of the stone above the ground at any time t can be described by the quadratic function h(t) = -16t^2 + 69t + 365.

Assuming that the acceleration due to gravity is -32 feet per second squared (neglecting air resistance), we can use the following kinematic equation to describe the height of the stone as a function of time:

h(t) = -16t²+ vt + h₀

where:

h(t) is the height of the stone above the ground at time t

v is the initial velocity of the stone (69 feet per second, in this case)

h₀ is the initial height of the stone (365 feet above the ground, in this case)

Substituting the values of v and h0, we get:

h(t) = -16t² + 69t + 365

Therefore, the height of the stone above the ground at any time t can be described by the quadratic function h(t) = -16t² + 69t + 365.

Answer:

When the survey was initially conducted, the average sales of smartphones was 1.7 million units.

Step-by-step explanation:

The exponential equation is P ( n ) = 1.7 ( b )ⁿ , where n is the number of years and P ( n ) is the annual sales of smartphones and the initial sales of smartphones was 1.7 million units

The exponential growth or decay formula is given by

x ( t ) = x₀ × ( 1 + r )ⁿ

x ( t ) is the value at time t

x₀ is the initial value at time t = 0.

r is the growth rate when r>0 or decay rate when r<0, in percent

t is the time in discrete intervals and selected time units

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

P ( n ) = 1.7 ( b )ⁿ

where , n is the number of years

And , P ( n ) is the annual sales of smartphones

Now , the value of b is the exponential growth factor

At the initial year , the number of smartphones sold is when n = 0

So , when n = 0

P ( 0 ) = 1.7 ( b )⁰

P ( 0 ) = 1.7 million units

Hence , the number of smartphones sold in initial year is 1.7 million units

Answer:

She can make 55 bracelets

Step-by-step explanation:

We have the correct question as follows;

Ariel bought a 15 1/6 foot long string, and a 12 1/3 foot long string. If each bracelet requires 1/2 of a foot long string, how many bracelets can Ariel make

we have the solution as follows

Firstly, we need to find the total length of the strings bought

We can get this by adding what was bought

That would be;

15 1/6 + 12 1/3

= 91/6 + 37/3

= (91 + 74)/6 = 27 1/2 ft

From the question, each bracelet requires 1/2 ft long

so the number of 1/2 ft long bracelets we can find will be;

27 1/2 divided by 1/2

= 55/2 * 2/1

= 55

The answer is B! I'm 100% sure!

Step-by-step explanation:

8% of $72.60 means 0.08*72.6 which equals 5.808. 20% of $72.60 means 0.2*72.6 which equals 14.52. 14.52+5.808=20.328. 20.328+72.6=92.928 which rounds up to $92.93. I hope this helps! Have a great rest of your day!

Answer:

She paid a total of $92.93 at the salon

Step-by-step explanation:

Well it costed $72.60 but then she did the sales tax which is 8% of 72.60 and then she did a tip which was 20% of 72.60. 8% of $72.60 is 5.81 and 20% of 72.60 is 14.52. Then you would add them to get $20.33 and then you would add the $20.33 to the $72.60 to get $92.93. SO she paid a total of $92.93 at the salon.

$5.81 + $14.52 = $20.33

$20.33 + $72.60 = $92.93

x^2 - 6x + 9 = (x - 3)^2

Step-by-step explanation:

To complete the square, add the square of half of the x-term coefficient.

Then use the factoring of a perfect square trinomial.

a^2 + 2ab + b^2 = (a + b)^2

a^2 - 2ab + b^2 = (a - b)^2
