Answer:
a) 91 1/6 gallons
b) 2502 miles
Step-by-step explanation:
You are given a number of miles and a number of gallons for the car. The ratio of these numbers is ...
(261 mi)/(14.5 gal) = 18 mi/gal
We presume this value is constant for this car. Then the questions can be answered by forming and solving a proportion:
a) 1641 miles/(gallons) = 18 mi/(1 gal)
Multiplying by gallons and dividing by 18 mi/gal, we get
1641/18 gal = (gallons) = 91 1/6 gal
It will take 91 1/6 gallons of gasoline for Mary to drive to her friend's house.
___
b) Same deal, but the miles are unknown.
(miles)/(139 gal) = (18 mi)/(1 gal)
Multiplying by 139 gal gives ...
(18 mi)·139 = (miles) = 2502 mi
139 gallons of gasoline will let Mary drive 2502 miles.
Answer:
25%
Step-by-step explanation:
let length of 1st square be x and second be y
then
A/q
x = y/2
area of first square = x^2 = (y/2)^2 = (y^2)/4
and
area of second square = y^ 2
so from sbove two lines
area of first square = 1/4 * area of second square
= 1/4 *100%
so..
area of first sqare = 25% of area of second square
20% off $250, 250 x 0.2= 50
The suit is $50 off, so $250-$50= $200
Answer:
B) 1.75 + 0.45m = 13.90
Step-by-step explanation:
To calculate the Taxi fare, we need to sum the fixed charge and the additional charge. Fixed charge ever is $1.75. The additional charge changes with the miles traveled (one mile costs $0.45, two miles $0.90, and so on), so we need multiply the charge ($0.45) by the miles m traveled.
1.75 + 0.45 m
The problem says that the fare was equals to $13.90 so the final equation is
1.75 + 0.45m = 13.90
