Answer:
Step-by-step explanation:
You;ll run into this formula a lot. Make sure you study it carefully.
A = 25
a = 5
d = 13
Find n
25 = 5 + 13*(n- 1)
20 = 13(n - 1)
This isn't going to work out. 20/13 does not give a whole number which it should.
You didn't give any choices, but the equation looks like this: 17 = 2x + 5. Solving that for x tells you that he went on a big water slide 6 times. 2 times 6 plus 5 is the $17 he spent at the park. See how well that works out?
Answer:
13.4feet
Step-by-step explanation:
The set up forms a right triangle.
Given
Height of the staircase h = 12 feet
Base of the stairs b = 6feet
Required
Length of the ramp l
Using the pythagoras theorem
l² = h² + b²
l² = 12²+6²
l² = 144 + 36
l² = 180
l = √180
l = 13.42 feet
Hence the length of the ramp to the nearest tenth is 13.4feet
Answer:
$8
Step-by-step explanation:
After the shoe purchase, her balance was $50 -45 = $5.
After depositing her babysitting earnings, her balance was $5+25 = $30.
After buying pizza, her balance was $30 -42 = -$12.
<em>Assuming no overdraft charge</em>, her balance after depositing her earnings was ...
-$12 +20 = $8
Sally's balance on Sunday was $8.
Answer:
x=7
Step-by-step explanation:
<u>If P is the midpoint of XY, then XP = PY:</u>
- 8x - 2 = 12x - 30
- 12x -8x = 30 -2
- 4x = 28
- x= 28/4
- x= 7
