Mark studies a group of 30 whales. If each whale weighed approximately 3.8 x 105 pounds, find the total weight of all 30 whales.
Yakvenalex [24]

Answer:

= 1.14 \times 10^{7}pounds

Step-by-step explanation:

If each whales weighed

3.8 \times  {10}^{5}

Then 30 whales weighed

30 \times 3.8 \times  {10}^{5}

=114 \times {10}^{5}

= 1.14 \times 10^{2}  \times {10}^{10}

Applying the law of indices we obtain

= 1.14 \times 10^{(2+ 5)}

=1.14 \times 10^{7}pounds

mamaluj [8]

Answer:

<h3>25%</h3>

Step-by-step explanation:

Total number of student in the school = 152 students

Number of student that have more than one pet = 38

percentage of the students have more than one pet will be expressed as

% of student with more than 1 pet = number of student with more than one pet/total number of student * 100%

% of student with more than 1 pet = 38/152 * 100

% of student with more than 1 pet = 3800/152

% of student with more than 1 pet = 25%

Hence 25% of the students in the school have more than one pet.
