Answer:
2.75 or 2 3/4
Step-by-step explanation:
1 + 1 = 2
1/4 + 1/2 = 3/4
1/4 = 1/4
make 1/2 into 2/4
add 1/4 to 2/4
3/4
2 + 3/4 = 2 3/4 or 2.75
Answer:
e = 10
Step-by-step explanation:
9e+4=-5e+14+13e
Combine like terms
9e+4=14+8e
Subtract 8e from both sides
9e-8e+4=8e-8e +14
e +4 = 14
Subtract 4 from each side
e+4-4 = 14-4
e = 10
6.
Intersecting chords:
RT x ST = PT x TQ
2 x 6 = 3 x TQ
12 = 3TQ
TQ = 12/3
TQ = 4
7.
AD = 90 -BE = 90-18 = 72
ADE = 180. DE = 180 - AD = 180-72 = 108
AE = 180. AB = 180-18 = 162
DE = 108
BD = BE +DE = 18 + 108 = 126
DAB = 72 + 162 = 234
ADE = 90 degrees
8.
AB^2 = BC* (BC +x)
8^2 = 2 * (2 +x)
64 = 4 + 2x
60 = 2x
X = 60/2
X = 30
The horizontal distance between the base of the ladder and the wall is 12.6 feet.
<h3>What is t
rigonometric ratio?</h3>
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let d represent the distance between the base of the ladder and the wall.
Using trig ratio:
cos(61) = d/26
d = 12.6 feet
The horizontal distance between the base of the ladder and the wall is 12.6 feet.

Answer:
A. t(n) = 20 + 60n
Step-by-step explanation:
Since Rob already had $20, the equation should have +20 to represent the money he already had.
60n can represent how much money Rob gets after washing windows, since he earned $60 from each weekend he washed windows.
So, A is the correct answer, t(n) = 20 + 60n
