Answer:
The total length of string needed for 17 identical decorative bottles is 35.70 meters
Step-by-step explanation:
Let us solve the question
∵ String A is 35 centimeters long
∵ String B is 5 times as long as String A
→ Multiply the length of A by 5 to get the length of B
∴ The length of string B = 35 × 5 = 175 cm
∵ Both are necessary to create a decorative bottle
∴ The length needed for 1 bottle = 35 + 175 = 210 cm
∴ Each bottle needs 210 cm to be decorated
∵ There are 17 identical bottles
→ Multiply the length needed for 1 bottle by 17
∴ The total length needed = 17 × 210 = 3570 cm
∴ The total length needed to decorate 17 bottles is 3570 cm
∵ 1 meter = 100 centimeter
→ Divide the total length by 100 to express it in meters
∴ 3570 cm ÷ 100 = 35.70 m
The total length of string needed for 17 identical decorative bottles is 35.70 meters
I think its... A (but not sure)
Answer:
b squared + 20b+ 100
Step-by-step explanation:
multiply Using the FOIL method
first inner outer last
so
b times b = b squared
10 times b equals 10b
b times 10 equals 10b (again)
10 times 10 equals 100
add up all the answers to get the final answer
b squared + 20b+ 100
Answer:
B
