Lily has 4 fewer ribbons than dora. lily has 7 ribbons . how many ribbons does dora have ?

Let L represent the number of ribbons Lily has and D be the amount of ribbons Dora has.

Since Lily has 4 fewer ribbons than Dora, the amount of ribbons Lily has can be represented as this:

L = D - 4

Because Lily has 7 ribbons, you can plug in 7 for L:

7 = D - 4

When you solve for the amount of ribbons Dora has (D), which is done by adding 4 to both sides, you get D = 11.

Therefore, Dora has 11 ribbons.

11

explanation: If Lily has 4 fewer ribbons than Dora then you should add 4+7 to get the answer.

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
