Amanda drove 348 miles using 15 gallons of gas. at this rate, how many gallons of gas would she need to drive 232 miles?

348 /15 = 23.2 miles per gallon

232 miles/ 23.2 miles per gallon = 10 gallons

10 gallons

Step-by-step explanation:

                                                                       15 gallons

Amanda's average speed is the unit rate = 0.043 gallon/mile

                                                                       348 miles

Her driving 232 miles would consume this much gas:

   0.0431 gallon/mile   times 232 miles, or 10 gallons.

146%

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
