Help please .. don’t understand
Grace [21]

Answer:

sinx = p/h , cosx = b/h , tanx = p/b

you can use these relations

Step-by-step explanation:

p = perpendicular = side opposite to the angle

h  = hypotenuse = side opposite to the right angle

b= base

if no angles are given, p and b can be interchanged

Willie and Emily each purchase one raffle ticket. If a total of seven raffle tickets are sold, what is the probability that Will
Nimfa-mama [501]

1/42

First, find the probability of Willie winning the grand prize. He has 1 ticket out of the 7 total tickets, so the probability is 1/7.

Now, find the probability of Emily winning the second prize. After the grand prize winner has been announced, there are only 6 tickets left. Emily has 1, so the probability is 1/6.

Finally, multiply the two probabilities together to find the probability that they will both happen together. To multiply fractions, multiply the numerators together and multiply the denominators together. This leaves us with (1 * 1) / (7 * 6), which is easy to simplify to 1/42, which is the final probability.

Sophia manages a landfill. She decides to measure the rate at which trash increases in volume to fill the landfill as the number
goblinko [34]

Answer:

\frac{m^3}{h}, \frac{cm^3}{h},  \frac{km^3}{h}

Step-by-step explanation:

If you look at the objects thrown as garbage, it's a two- or three-dimensional item that takes up space and also has mass and this is a solid waste.

And the landfill that dumps such garbage is also three-dimensional.

Hence, the volume module, if the object inside is a solid, either would be

m^3,cm^4,Km^3

As household numbers rise, landfill space increases.

So,

household\ number = Proportionality\times  landfill\ space

If H represents the number of household keeps,  then it will be a sufficient unit for the purpose of Sophia that is

\frac{m^3}{h}, \frac{cm^3}{h},  \frac{km^3}{h}

Arnoldo needs to write this system in slope-intercept form. Which shows how he could do that?
Jobisdone [24]

Answer:

y =  \frac{3}{2}x - 3

y =  \frac{1}{8} x -  \frac{7}{8}

Step-by-step explanation:

The given system is

3x-2y=6

0.4(20y+15)=x

The slope intercept form is y=mx+c.

For the first equation, 3x-2y=6, we add -3x to both side -2y=-3x+6

y =  \frac{3}{2}x - 3

For 0.4(20y+15)=x, we expand to get:

8y  + 7 = x

8y= x - 7

Divide through by 8

y =  \frac{1}{8}x -  \frac{7}{8}

Therefore the system in slope-intercept form is:

y =  \frac{3}{2}x - 3

y =  \frac{1}{8}x -  \frac{7}{8}
