Cucumbers are sold for 3.50 QAR per kilogram. If you purchase 0.7kg of cucumbers how much will it cost? a. 5.95QAR b. 4.20 QAR c. 2.80QAR d. 2.45QAR

Answers

Answer:

d. 2.45 QAR.

Explanation:

To calculate the cost of purchasing 0.7kg of cucumbers at a rate of 3.50 QAR per kilogram, we can use the formula:

Cost = Rate × Quantity

Here's how to calculate it:

1. Multiply the rate per kilogram (3.50 QAR) by the quantity (0.7kg):

- Cost = 3.50 QAR/kg × 0.7kg

2. Calculate the result:

- Cost = 2.45 QAR

Therefore, the cost of purchasing 0.7kg of cucumbers at a rate of 3.50 QAR per kilogram is 2.45 QAR.

A hybrid car can travel 40 miles per gallon. Approximately how many gallons of fuel will the car need to travel 20 km?A. 0.3
B. 0.8
C. 2.5
D. 3.2

Answers

Answer:

correct option is A

20 km we need 0.3 gallon fuel

Explanation:

given data

gallon = 40 miles

distance = 20 km

to find out

how many gallons of fuel

solution

we know that 20 km = 12.4274 miles

and

we know here car is travel 40 miles per gallon

it mean here that

40 miles = 1 gallon

1 miles = 1/ 40 gallon

and

12.4274 miles = 1/40 × 12.4274 gallon

solve it to get gallon of 20 km or

12.4274 miles = 0.31 gallon

so in 20 km we need 0.3 gallon fuel

correct option is A

Answer:

The number of gallons are 0.3.

A is correct option.

Explanation:

Given that,

A hybrid car can travel 40 miles per gallon

We need to calculate the mile/gallon to km/gallon

Gallon is the unit of liquid and miles and kilometer are the unit of distance.

$40\ miles/gallon = 64.3738\ km/gallon$

We need to calculate the number of gallons of fuel

Number of gallon $N=(20)/(64.3738)$

$N=0.3$

Hence, The number of gallons are 0.3.
