20 gallons
First you have to find the ratio or unit rate so 105/15= 140/x x is the gasoline needed so when you cross multiply you get 2100/105x divide both sides by x and you get 20

Could you guys please help me with number 1
Ivahew [28]

Answer:

Option B 6 30 am

Step-by-step explanation:

step 1

Sum all the times

(45+5+10+30+15)=115 minutes

Convert minutes to hours

we know that

60 minutes = 1 hour

so

115 minutes=60+55= 1 hour 55 minutes

Subtract 1 hour 55 minutes from 8 25 am

(8 25 am)-(1 hour 55 minutes)=(8 25 am-1 hour)-(55 minutes)

=7 25 am-55 minutes

=7 25 am-(25+30) minutes

=(725 am-25 minutes)-(30 minutes)

7 00 am-30 minutes

=6 30 am

A set of pulleys is used to lift a piano with a mass of 102 kg. The piano is lifted 3 meters in 1 minutes. How much power is use
agasfer [191]

Answer:

50.031 watts

Step-by-step explanation:

Formula

Power = Force * distance / time

The units are critical

distance = meters

time = seconds

force = newtons = kg * m / s^2

Solution

F = m * a

a = 9.81

m = 102 kg

F = 102 * 9.81 = 1000.62 Newtons

T =  minute = 60 sec/min * 1 min

T = 60 seconds

d = 3 meters

Power = 1000.62 * 3 / 60

Power = 50.031

A car driver charges 2$ for first 1/4 mile and for every next 1/4th mile he charges 0.3$ for 6 miles distance.how much would be
Oduvanchick [21]

Answer:

$8.90

Step-by-step explanation:

$2 for the 1/4 mile. That leaves 5 3/4 more miles until 6 miles. He charges 30 cents for each additional 1/4 miles, and there are twenty-three 1/4ths in 5 3/4. So, 23*30=690, which is basically $6.90 because it's 690 cents.

$6.90+$2=$8.90
