Answer:
The ladder has 20 steps
Step-by-step explanation:
10 is the direct middle if you go down 4 that is 6, if you go back up 7 you get 13 and if you go back down 13 and you are on the first step 13-13 is 0, so the ladder has 20 steps.
Answer:
34.48cm²
Step-by-step explanation:
Assuming the shaded area doesn't contain the triangle:
area of triangle = bh/2
area of triangle = 4(2)/2
area = 4
area of circle = πr²
area = π3.5²
area = 38.48
area of shaded = 38.48 - 4
area = 34.48cm²
So first I saw that u need 1 adult with every 6 children so I did 6*4 and got 24. From that I got 4 adults with 2 leftover children. For the other class which has 28 children, u would still need 4 adults. Now since u said the teacher is included as an adult only 3 more are needed for the trip, and that is your answer.

Answer:
x⁷ = 60

- The expotential equation .
<u>Solution</u><u> </u><u>:</u><u>-</u><u> </u>
Given logarithmic equation is ,
⇒ log x⁵ + log x ¹² = 7
⇒ log x ⁵ * ¹² = 7 [ log aⁿ + log aⁿ' = log aⁿ * ⁿ' ]
⇒log x ⁶⁰ = 7
In expotential form we can write it as ,
⇒ x⁷ = 60
