No, because 11.6/2 is 5.8 so 5.8 is half of the tank. if it uses 1.45 per hour and it's used for 3.5 hours there will only be 5.075

Answer: NO because 5.075g (gasoline available after 3.5 hours) < 5.8g( half full tank)

Step-by-step explanation:

Hi, to solve this problem we have to calculate how many gallons has a half-full tank. If the tank holds 11.6 gallons we have to divide it by 2.

  • 11.6 /2 = 5.8 gallons (half-full tank)

So, to know if the tank is more than half full of gasoline after 3.5 hours we have to multiply the gallons used in an hour (1.45) by the amount of time (3.5) and compare.

  • 1.45 g/h x 3.5 h = 5.075

In conclusion, after 3.5 hours the the tank is not more than half full of gasoline, because 5.075 < 5.8.

Feel free to ask for more if it´s necessary or if you did not understand something.

Last night, Roberto spent 90 minutes doing homework, infinity symbol hour reading, and 540 seconds making his lunch for the next
Margarita [4]

Answer:

41 minutes

Step-by-step explanation:

We are given;

Time spent on homework = 90 minutes

Time spent reading = 2/3 hours = 2/3 × 60 minutes = 40 minutes

Time spent making lunch = 540 seconds = 540/60 minutes = 9 minutes

We want to find how many more minutes Roberto spent doing homework than he did reading and making his lunch.

Thus;

Time spent on reading and making lunch = 40 + 9 = 49 minutes

Hence, the word "how many more" means we will subtract 49 from 90.

So, "how many more minutes" = 90 - 49 = 41 minutes

Can u guys help me with these two problems?? for the first one I got 76 ,but I don't think is right.
Elina [12.6K]

Answer:

See below

Step-by-step explanation:

15)

In the right-angle triangle, once one of the angles is 44º, then, the unknown angle is x.

180 = 44 + 90 + x

180 = 134 + x

x= 46

The angle y of the other triangle plus the angle x of the right-angle triangle is equal to 90º, therefore they are complementary angles.

So,

90 = x + y

90 = 46 + y

y=44

To find ?, we have

180 = 58 + 44 +?

180 = 58 + 44 +?

? =78

16)

The sum of the internal angles of the triangle with angles 50º and 25º is equal to 180º, therefore, the other angle is

180 = x + 50 + 25\\180 = x+ 75\\x=105

Once the angles are opposite, they are the same. For the triangle with the 36º angle, we have

180 = 36 + 105 + y

180 = 141+ y

y=39

?=39
