Write an equation to represent the following : 30 students can fit on a bus . If b buses are used and 3 students were left over

anzhelika [568]

30b+3= s

It would be thirty students times the number of buses, with an addition of 3 students equal to the total number of students when on the field trip.

I hope this helps!

Roger can run one mile in 18 minutes. jeff can run one mile in 15 minutes. if jeff gives roger a 1 minute head start, how long w

gladu [14]

Alright, lets get started.

Roger can run one mile in 18 minutes.

Jeff can run one mile in 15 minutes.

Suppose in x minutes, they both will catch up.

Roger runs in 18 minutes = 1 mile

So, Roger will run in 1 minute = $\frac{1}{18}$ miles

So, Roger will run in x minutes = $\frac{x}{18}$ miles

Jeff runs in 15 minues = 1 mile

So, Jeff will run in 1 minute = $\frac{1}{15}$ mile

As Jeff gives roger a 1 minute head start, means Jeff will have x-1 minute time to run

So, Jeff will run in (x-1) minute = $\frac{x-1}{15}$

As both are cathing up means they both runs same distance, means

$\frac{x}{18} =\frac{x-1}{15}$

Cross Multiplying

$15 x = 18x - 18$

$3 x = 18$

x = 6 minutes

So for calculating distance = $speed * time$

Distance = $\frac{1}{18} *6 = \frac{1}{3}$ miles

It means it will take 1/3 or 0.33 miles before jeff catches up to roger. : Answer

Hope it will help :)

The hypotenuse of an isosceles right triangle is 16 centimeters. Find the length of the 2 other sides of the triangle to the nea

scZoUnD [109]

Right triangle means we can use a^2+b^2=c^2
isosceles means 2 sides are equal legnths

the hypotenuse is normally the longest side so the equal sides are the other sides so therefore
a=b
therefor
(a^2)+(a^2)=c^2
2(a^2)=16^2
2(a^2)=256
divde both sides by 2
a^2=8
the side legnth of the other 2 sides is the square root of 8 which is aprox 2.8284271247452
but we only want the tenth so we look at the hundreths as well
2.82
round to the nearest tenth
2.8 cm is the answer of the legnths
