I have math questions I need to check my answers can you please help me 1. 4x4x4x4x4 as a power of 4 answer 4 to the fifth power
2.a bedroom is 10 ft by 11 ft what is the perimeter? answer 42 ft
evaluate 72/8-9/3=6
3.Jamal is fencing a rectangular field that measures 25 ft by 21 ft how much fencing should he buy? ==92 ft
4.give place value of the 8 in 138,350 =thousands
5.one kilometer is equal to 1,000 meters what fractional part of a kilometer is 700 meters? simplfy == 7/10
6.list factors of 42 2,3,6,7,14,21
All good, well done! :)
Sure, I can help you with your math questions!
1. To find the answer to 4^5 (4 to the fifth power), you simply need to multiply 4 by itself five times: 4 x 4 x 4 x 4 x 4 = 1,024. So the answer is 1,024.
2. The perimeter of a rectangle is found by adding up all the sides. In this case, the bedroom is 10 ft by 11 ft. So the perimeter is calculated by adding all the sides: 10 + 10 + 11 + 11 = 42 ft. Therefore, the perimeter of the bedroom is 42 ft.
3. To find the amount of fencing Jamal needs to buy, we need to calculate the perimeter of the rectangular field. The length of the field is 25 ft and the width is 21 ft. The formula for calculating the perimeter of a rectangle is P = 2*(L + W), where P is the perimeter, L is the length, and W is the width. Plugging in the values, we get P = 2*(25 + 21) = 92 ft. So, Jamal should buy 92 ft of fencing.
4. In the number 138,350, the 8 is in the thousands place. Place value refers to the position of a digit within a number, and each position represents a different power of 10. From left to right, the positions are: thousands, hundreds, tens, and ones. So in this case, the 8 represents 8 thousand.
5. To determine what fractional part of a kilometer is 700 meters, we need to divide 700 meters by 1,000 meters (since one kilometer is equal to 1,000 meters). This simplifies to 7/10. So, 700 meters is 7/10 of a kilometer.
6. To find the factors of 42, we need to identify the numbers that can evenly divide 42 without leaving any remainder. The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, and 42. These numbers can be multiplied together to give 42.
