Adam jogs at an average speed of 10km/h from his house to the airport. The airport is 7km away from his house. At what time must Adam leave his house in order for him to reach the airport at 7:20 am.

Answer:

19 hours

Step-by-step explanation:

You have 279. First, devide the 279 by 9(dollar amount).

279/9 = 31

So combined they work 31 hours. Subtract 7 from this, since we know Katya worked 7 extra hours. Youll now have 24.  (31-7 = 24)

Next, divide this number in half, which will get you what they both worked before Katya worked an extra 7 hours.

24/2 = 12.

Now that we know they both worked 12 hours, we can just add back the 7 hours Katya worked.

12+7 = 19.

So the answer to how many hours katya worked will be:

19 hours

Answer:

26 hotdogs

76 sodas

Step-by-step explanation:

x - 50 for hot dogs

x  for sodas

(x-50) + x = 102

2x -50 = 102

2x = 152

x = 76

76-50 = 26 hotdogs

76 sodas

Answer: 14 red, 7 green, 44 blue

Step-by-step explanation:

First, use the letter r as a variable to represent the number of red Legos. The number of green Legos (g) is 7 less than the number of red Legos, or g = r-7. The number of blue Legos (b) is 2 more than 3 times the number of red Legos, or b = 3r+2. The total number of Legos is the number of red + green + blue Legos, which can be represented as 65 = r+g+b.

Substitute the equations for g and b in. This should give you a final equation of 65 = r+(r-7)+(3r+2). To solve for the number of red Legos, first add up all of the terms to get 65 = 5r-5. Now add 5 to each side (70 = 5r). Finally, divide each side by 5 (r = 14).

To find the number of green Legos, substitute the number of red Legos (14) into the equation for the green Legos (g = r-7). This should get you the equation g = 14-7 which simplifies to g = 7.

To find the number of blue Legos, substitute the number of red Legos (14) into the equation for the blue Legos (b = 3r+2). This gives you the equation b = (3*14)+2. First, multiply 3 and 14 to get b = 42+2. Finally, add them together to get b = 44.

Answer:

x= 25 degrees

Step-by-step explanation:

A triangle has a total of 180 degrees.

110 degrees + 45 degrees = 155 degrees

180 degrees - 155 degrees = 25 degrees

Answer:

-18r + 27s

Step-by-step explanation:

You would multiply 2r and -3s by -9.

Answer:

The volume of the smaller solid is 72 cm.

Step-by-step explanation:

Given that two similar solids have surface areas of 48cm and 108cm respectively, to find the volume of the smaller solid if the bigger one has a volume of 162cm the following calculation must be performed:

108 = 162

48 = X

48 x 162/108 = X

7776/108 = X

72 = X

Therefore, the volume of the smaller solid is 72 cm.

Answer:

45

Step-by-step explanation:

Total mini chocolates in a bowl= 85

ration of kit kats to hersheys bars = 8:7

ration of kit = 8

Total ratio= 15

Number of kit kats= ratio of kit Kat/ total ratio × total number of mini chocolates

Number of kit Kat = 8/15 × 85= 45

Hence, there are 45 kit kats present there.

Answer:

There were about 45 kit kats.

Step-by-step explanation:

With the information provided, you know that the the ratio of kit kats to hersheys bars is 8:7 and that there are 85 mini chocolates in a bowl, so to be  able to find the number of kit kats there first you can say that you have 15 units because if you add the numbers on the ratio 8+7=15. Then, you divide the total amount of mini chocolates by the units to find the number of chocolates in each unit:

85/15=5.66

Now, you can multiply the ratio of hersheys bars which is 7 for the number of chocolates per unit to find the amount of hersheys bars:

7*5.66=40

Finally, you can multiply the ratio of kit kats which is 8 for the number of chocolates per unit to find the amount of kit kats:

8*5.66=45

According to this, the answer is that there were about 45 kit kats.
