Boyd grows only tomatoes and raspberries in his garden. last year, he grew 140 pounds of tomatoes and 60 pounds of raspberries. this year, the production, by weight, of tomatoes declined by 20 percent, and the production, be weight, of raspberries declined by 50 percent. by what percentage did the total yield, by weight, of boyd's garden decline

29%.

Step-by-step explanation:

We have been given that Boyd grew 140 pounds of tomatoes and 60 pounds of raspberries. This year, the production, by weight, of tomatoes declined by 20 percent, and the production, be weight, of raspberries declined by 50 percent.

First of all, we will find the weight of tomatoes and raspberries using the given information.

Since the production, by weight, of tomatoes declined by 20 percent, so this year production of tomatoes is 80% of 140 pounds.

Since the production, be weight, of raspberries declined by 50 percent, so this year production of raspberries is 50% of 30 pounds.

Total production this year: pounds.

Now, we will percent decrease formula.

Therefore, the total yield, by weight, of Boyd's garden declined by 29%.

29 percent

Step-by-step explanation:

First I found the total amount of produce this year : 140 + 60 = 200 pounds

20 percent of 140 is 28 and 50 percent of 60 is 30.

28 + 30 = 58

Now that we have that we need to find what percent 58 is of 200.

58/200 simplified is 29/100 or 29 percent.

(We divide by 2 with both the denominator and the numerator.)

Therefore the answer is 29 percent. Have a nice day!

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
