Use the digits 5,4 and 8 once each to write an odd number greater than seven hundred

845 because 800 is greater than 700 and 845 is an odd number because it ends in 5 (which is an odd number).

fenix001 [56]

Answer:

100/40=25

25*30=750

so 750 students would dislike the new starting time.

I really hope this was correct and helpful. I tried my best.

A line includes the points (0,2) and (1,6) What is the equation of the line in slope intercept form?

erica [24]

Answer:

y = 4x + 2

Step-by-step explanation:

$\frac{y^{2}-y^{1} }{x^{2} -x^{1} }$

$\frac{6-2}{1-0} = \frac{4}{1}$

y = 4x + 2

Solve the equation for the given variable. justify each step.

s344n2d4d5 [400]

Answer: y= $\frac{5-9x}{2}$

s=-30+10t

Step-by-step explanation:

9x + 2y = 5; y

9x-9x+2y = 5-9x

2y=5-9x

y= $\frac{5-9x}{2}$

1/15s - 2/3t = -2; s

(1/15s - 2/3t = -2)*15 ==> Get rid of fraction by multiplying both sides by 15

s - 30/3 t=-30

s-10t=-30

s=-30+10t

Jill is standing at the base of her apartment building. She measures the angle of elevation to the top of a nearby tower to be 4

Greeley [361]

Let the distance of Jill form the base of the tower be x, then tan 40 = 100/x
x = 100/tan 40 = 100/0.8391 = 119.18 meters

Let the height of the tower from the level of the top of Jill's apartment be y, then tan 30 = y/119.18
y = 119.18 x tan 30 = 68.8 meters

Therefore, the height of Jill's apartment is 100 - 68.8 = 31.2 meters
