answer:Let's break this problem down step by step.Since the mother dolphin is 18 years old and three times older than the mother seal, we can calculate the mother seal's age as follows:Mother seal's age = Mother dolphin's age / 3 = 18 / 3 = 6 years old.Now, we need to calculate the age of the babies. The baby dolphin's age is one-third the age of its mother, so:Baby dolphin's age = Mother dolphin's age / 3 = 18 / 3 = 6 years old.Similarly, the baby seal's age is one-third the age of its mother, so:Baby seal's age = Mother seal's age / 3 = 6 / 3 = 2 years old.Now, we need to calculate the total age of the babies in 7 years. In 7 years, the baby dolphin will be 6 + 7 = 13 years old, and the baby seal will be 2 + 7 = 9 years old.So, the total age of the babies in 7 years will be 13 + 9 = 22 years.Thus, the total age of the babies in seven years is boxed{22}.

answer:To calculate the total number of words in the poem, we need to multiply the number of stanzas, the number of lines per stanza, and the number of words per line.Number of stanzas: 20Number of lines per stanza: 10Number of words per line: 8Total number of words = 20 * 10 * 8 = 200 * 8 = 1600Thus, the total number of words in the poem is boxed{1600}.

answer:Let's break down the problem. Since it's buy two get one free, for every 3 pounds of chicken breasts, Emily only pays for 2 pounds.So, we can divide the total number of pounds (30) by 3 to get the number of "deals" she gets: 30 ÷ 3 = 10 deals.In each deal, she pays for 2 pounds, so she pays for a total of 10 x 2 = 20 pounds.The price per pound is 8, so she pays a total of 20 x 8 = 160.Thus, Emily paid boxed{160} dollars for the chicken breasts.

answer:Let's calculate the total number of batches of cookies Sophia and Olivia have baked.Sophia can bake 4 batches of cookies per hour.So in 6 hours, Sophia has baked 4 * 6 = 24 batches of cookies.Olivia can bake 6 batches of cookies per hour.So in 6 hours, Olivia has baked 6 * 6 = 36 batches of cookies.The total number of batches of cookies they have baked is the sum of batches Sophia and Olivia have baked.This amounts to 24 + 36 = 60 batches of cookies.So Sophia and Olivia have baked boxed{60} batches of cookies.

answer:To solve the problem, we'll break it down into steps.First, let's calculate the total number of stems in Emily's garden. Since there are 25 bushes and each has 120 stems, we multiply the number of bushes by the number of stems per bush to find the total number of stems:25 * 120 = 3000 stems.Next, we need to determine how many stems produce 3 flowers and how many produce 6 flowers. 40% of the stems produce 3 flowers. To find 40% of 3000, we multiply 3000 by 40/100:3000 * 40/100 = 120000/100 = 1200 stems.This means the remaining stems produce 6 flowers. Since there are 3000 stems in total and 1200 produce 3 flowers, the number of stems that produce 6 flowers is:3000 - 1200 = 1800 stems.Now, we calculate the total number of flowers produced by each type of stem and add them together. For the stems that produce 3 flowers, the total number of flowers is:1200 * 3 = 3600 flowers.For the stems that produce 6 flowers, the total number of flowers is:1800 * 6 = 10800 flowers.Finally, we add the total number of flowers from both types of stems to find the total number of flowers in Emily's garden:3600 + 10800 = 14400 flowers.Thus, Emily's garden contains boxed{14400} flowers.

answer:Let's break it down step by step:Half the cows is 18 / 2 = 9 cows.5 more than half the cows is 9 + 5 = 14 cows.So, 14 cows are black.To find the number of cows that are not black, we subtract the number of black cows from the total number of cows:18 - 14 = 4.Thus, there are boxed{4} cows that are not black.
