Answer:

39\ miles/gallon

Step-by-step explanation:

Let

x------> Karla's car mileage

1) First way

we know that

100%-35%=65%=65/100=0.65

so

x=0.65(60 miles/gallon)=39 miles/gallon

2) Second way

by proportion

\frac{60}{100} \frac{(miles/gallon)}{\%} =\frac{x}{65} \frac{(miles/gallon)}{\%}\\ \\x=60*65/100\\ \\x=39\ miles/gallon

Nata [24]

Answer:

Step-by-step explanation:

Clair delivery=79 per day

Total delivery per year=79×365 days

=28,835

Reagan delivery=2490 per month

Total delivery per year=2490×12 months

=29,880

Anthony delivery= 616 per week

Total delivery per year =616×52 weeks

=32,032

Total delivery altogether in a year=28,835+29,880+32,032

=90,747

What is the measure of ∠C in the figure below
sertanlavr [38]

Answer:

C. 56°

Step-by-step explanation:

An isosceles triangle has two sides that are equal. ∆ABC has two equal sides. Thus, the angles opposite the two sides of an isosceles triangle are also congruent to each other.

<C and <A are congruent to each other.

m<A = 56°, therefore,

m<C = 56°
