Answer:

Lizzy's recipe is not a proportional relationship with the brownie recipe because of the difference in ratio.

Step-by-step explanation:

Brownie recipe:

Cocoa powder = 3 parts

Flour = 2 parts

Ratio of cocoa powder to flour = 3 : 2

Lizzy's recipe:

Cocoa powder = 1 cup

Flour = 1 cup

Ratio of cocoa powder to flour = 1 : 1

XB is the angle bisector of ZAXC. MZAXB23А.BVхC с
neonofarm [45]

To obtain x, we can sum the angles < AQB and < BQC

=> 5X + 8X - 24

=> 13X -24

we are also told that that the sum of their angles is 80

13X - 24 = 80

13 X = 24 + 80

13X = 104

Divide both sides by 13

x = 104/13

x = 8

Car A is rated at 32 ​mi/gal (miles per​ gallon) for city driving and 29 ​mi/gal for highway driving. Car B is rated at 27 ​mi/g
Irina18 [472]

The gallons of gas that each vehicle would consume for the different amounts of driving are as follows:

a) For 300 mi of city driving plus 100 mi of highway driving, car A will consume <u>12.825 gallons</u> of gas, while car B will consume <u>14.05 gallons</u> of gas.

b) For 100 mi of city driving plus 300 mi of highway driving, car A will consume <u>13.475 gallons</u> of gas, while car B will consume <u>12.52 gallons</u> of gas.

<h3>Data and Calculations:</h3><h3>Rating (miles per gallon)</h3>

                                           City Driving     Highway Driving

Car A                                     32 mi/gal            29 mi/gal

Car B                                     27 mi/gal            34 mi/gal

<h3>Miles of Driving</h3>

                   City Driving     Highway Driving

a)                       300 mi              100 mi

b)                       100 mi              300 mi

<h3>Car A's Consumption of Gas:</h3>

                   City Driving               Highway Driving              Total

a)              9.375 gal.(300/32)         3.45 gal. (100/29)        12.825 gal.

b)              3.125 gal.(100/32)         10.35 gal    (300/29)     13.475 gal.

<h3>Car B's Consumption of Gas:</h3>

                   City Driving               Highway Driving             Total

a)                11.11 gal. (300/27)         2.94 gal. (100/34)         14.05 gal.

b)              3.70 gal. (100/27)          8.82 gal. (300/34)        12.52 gal.

Thus, different driving ratings (miles per gallon) show the differences in gas consumption by vehicles in city driving and highway driving.

We have that the total length of paper needed to cover all the tables is

X=288.5ft

From the question we are told that:

Number of tables n=36

Length of tablel=8

Extension e=3 inch =>0.25feet

Generally, the equation for the Total length  tables is mathematically given by

l_t=n*l\\\\l_t=36*8

l_t=288ft

Therefore with an extension of 0.25ft at both end we have the Total length of  tablecloths to be

X=l_t+2(e)\\\\X=288ft+2(0.25)

X=288.5ft

In conclusion

The total length of paper needed to cover all the tables is

X=288.5ft
