Dario’s school has rented several buses to take students on their field trip to visit the Science Museum in the neighboring town

. Each bus can hold 64 people, including the bus driver. The driver said that the museum is 153.82 miles away from school. A total of 360 students, teachers and chaperones are going on the trip. A total of six buses were rented for this field trip. The bus company charges $0.645 per mile, per bus. What will the total bus cost for this trip (rounded to the nearest cent)?

The number of people is extra information, all you need is 153.82*2 (for the trip and back) * .645, which I believe will be $198.43, but it might be best to check that math to be safe

Hi guys . pls help me with this​
daser333 [38]

Step-by-step explanation:

The upstream speed is S / t₁, and the downstream speed is S / t₂.

If we say f is the speed of the fish in calm water, and r is the speed of the river, then:

f − r = S / t₁

f + r = S / t₂

If we say T is the time it takes to cross the river, then the speed perpendicular to the river is ℓ/T, the speed parallel to the river is r, and the overall speed is f.

Using Pythagorean theorem:

f² = (ℓ/T)² + r²

f² − r² = (ℓ/T)²

(f − r) (f + r) = (ℓ/T)²

(S / t₁) (S / t₂) = (ℓ/T)²

S² / (t₁ t₂) = (ℓ/T)²

(t₁ t₂) / S² = (T/ℓ)²

√(t₁ t₂) / S = T/ℓ

T = ℓ√(t₁ t₂) / S

1. The sum of the angles is 90° The difference between twice the larger angle and the smaller
Ostrovityanka [42]

Answer:

\displaystyle 25°\:and\:°65

Step-by-step explanation:

{90° = m∠1 + m∠2

{105° = 2m∠1 - m∠2

_______________

\displaystyle \frac{195°}{3} = \frac{3m∠1}{3} \\ \\ 65° = m∠1

All you have left to do is this:

\displaystyle 25° = -65° + 90°

So, your two angle measures are \displaystyle 25°\:and\:°65.

I am joyous to assist you anytime.

Alex and Freddy collect stamps. The number of stamps in Alex’s collection is in ratio 3:5 to the number of stamps in Freddy’s co
Tems11 [23]
Suppose Alex has 3x stamps, Freddy has 5x stamps. After Freddy gives Alex 10 stamps, Alex has 3x+10 while Freddy has 5x-10
the new ratio is 7 to 9, so we have the equation: (3x+10)/(5x-10)=7/9
9(3x+10)=7(5x-10)
27x+90=35x-70
160=8x
x=20
So Alex has 3*20=60 stamps while Freddy has 5*20=100. Together they have 160
