Answer:
1/23
Step-by-step explanation:
The perpendicular slope will be the opposite reciprocal of the original slope so if slope of c is -23, slope of d is 1/23

Answer:
babysitting
Step-by-step explanation:
To find per hour just divide made/hours
49.5/6= $8.25 per hour for gardening
38.6/4= $9.65 per hour for babysitting
8.25<9.65
she earned more babysitting

Answer:
91.8 ft
Step-by-step explanation:
So we can talk about the diagram, let's name a couple of points. The base of the tree is point T, and the top of the tree is point H. We want to find the length of TH given the length AB and the angles HAT and ABT.
The tangent function is useful here. By its definition, we know that ...
TA/BA = tan(∠ABT)
and
TH/TA = tan(∠HAT)
Then we can solve for TH by substituting for TA. From the first equation, ...
TA = BA·tan(∠ABT)
From the second equation, ...
TH = TA·tan(∠HAT) = (BA·tan(∠ABT))·tan(∠HAT)
Filling in the values, we get ...
TH = (24.8 ft)tan(87.3°)tan(9.9°) ≈ 91.8 ft
The height <em>h</em> of the tree is about 91.8 ft.
