J. D built a tower out of blocks with his nephew. Each block was 1 3/4 inches tall, except the top block, which was only 1 inch tall. They built a 44 3/4 inch tall tower. How many blocks did they use?

26 including the top block.

Step-by-step explanation: Subtract 1 from 44.75. Divide by 1.75. Ans=25. Add top block. Ans=26.

26 blocks

Step-by-step explanation:

44 3/4-1=43 3/4

43 3/4 divided by 1 3/4 equals 25 blocks

add the top block and you get 26 total blocks

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =
