(1) 34.8 liters

(2) $63.55

Solution:

(1) There is a mistake in question. It is 42 liters.

Total gasoline a car can hold = 42 liters

Liters of gasoline filled in beginning of the week = 35.8

Liters of gasoline used during the week = 28.6

Remaining liters of gasoline in the tank = 35.8 – 28.6

                                                                  = 7.2 liters

Quantity of gasoline need to buy to fill the tank completely

                               = Total capacity – Remaining gas in the tank

                               = 42 liters – 7.2 liters

                               = 34.8 liters

Hence Alberto need to buy 34.8 liters of gasoline to fill the tank.

Option B is the correct answer.

(2)

Shamika earns in first week = $25.75

Shamika earns in next week = $37.80

Total money Shamika have = First week earning + Second week earning

                                              = $25.75 + $37.80

                                              = $63.55

Don't add or subtract spending money, because the question is how much she have from these two weeks.

Hence Shamika have $63.55 from these two weeks.

icang [17]

Answer: No

Step-by-step explanation:

According to triangle inequality theorem which state that: the sum of any 2 sides of a triangle must be greater than the measure of the third side.

Now let's test the given parameters if they obey this theorem

4 inches, 5 inches and 1 inch

4 + 5 = 9

9 > 1 correct

5 + 1 = 6

6 > 4 correct

4 + 1 = 5

5 not > 5 wrong

Therefore he won't be able to create the triangular component with these toothpicks without modifying any of the lengths

Pls help me!!!! I'm stuck on how to solve this!!??
Luda [366]
Let A represent the value of the car after each year.
A= initial value (P)×(1+percent increase(r)) ^time
A=P×(1+r)^t
A=18710×(1+(-12%))^8
A=18710×(1-12%)^8
A=18710×(1-0.12)^8
A=18710×(0.88)^8
A= 6728.7619591115
The best approximation is 6729
Therefore the value of the car will be about $6729 after 8 years
Your answer is B.
