Answer:

70 cm

Step-by-step explanation:

$\frac{1}{5 * 10^{6} } = \frac{d}{350} \\\\d = \frac{350}{5 * 10^{6} } \\\\d = 7 * 10^{-5} km = 7 * 10^{-5} * 10^{6} cm = 70 cm$

earnstyle [38]

If there are 18 students every one of the will pair up with 17 other students throughout the year so the total amount of pairs that can be made is 18x17=306 but since it’s not important if student A is paired with student B or student B with student A we should divide the total amount of pairs by two- 306:2=153 so in total there will be 153 projects finished

I WILL GIVE YOU BRAINLIEST IF YOU ANSWER THE WHOLE QUESTION.

Answer:

B) $y=2x$ and C) $y=-7x+9$

Step-by-step explanation:

Once a linear function has a constant rate of change, you just have to find the linear functions. Also, the other ones are quadratic functions, and their graph are parabolas, which don't have a constant rate of change.

Considering $f(x)=y$

$f(x) = 2x$ has a constant positive rate of slope 2.

$\frac{dy}{dx}=2$

$f(x)=-7x+9$ has a constant negative rate of slope -7

$\frac{dy}{dx}=-7$

Pls help me with this problem!!!!

Answer: 55°

Step-by-step explanation:

∠YAZ + ∠YAX = 180° because they are linear pairs

∠YAZ + ∠YAX = 180°

∠YAZ + 125 = 180

Subtract both sides by 125

∠YAZ = 55°

Hope that helped!
