Answer:

a = 0.6; b = 0.4; c = 0.2; d = 0.8

Step-by-step explanation:

The value of a represents the 180 out of 300 in the first row.  180/300 = 0.6.

The value of b represents the 120 out of 300 in the first row.  120/300 = 0.4.

The value of c represents the 40 out of 200 in the second row.  40/200 = 0.2.

The value of d represents the 160 out of 200 in the second row.  160/200 = 0.8.

While in Europe, if you drive 117 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per lite
Hoochie [10]

You would spend $63.58 on gas per week.

Step-by-step explanation:

Given,

Distance per day = 117 km

Distance in a week = 117*7 = 819 km

1 km = 0.6214 mile

819 km = 819*0.6214 = 508.93 miles

Car's mileage = 42.0 mi/gallons

Let,

x be the gallons for 508.93 miles

x gallons = \frac{508.93}{42}=12.12

Therefore,

12.12 gallons of gas is needed for one week.

1 US gallon = 3.785 liters

12.12 gallons = 12.12*3.785

12.12 gallons = 45.87 liters

Cost of gas per liter = 1.10 euro

Cost of 45.87 liters = 1.10*45.87 = 50.457 euros

1 euro = $1.26

50.457 euros = 1.26*50.457 = $63.58

You would spend $63.58 on gas per week.

X^2-x-7=0 complete the square
lesya692 [45]
Hello there!
Use the formula ( \frac{b}{2} )^2 in order to created a new term. Solve for x by using this term to complete the square.
x= \frac{1}{2}±  \frac{ \sqrt{29} }{2}

Hope this helps! :)
