A 35 ft ladder reaches a
window that is 25 feet high. What is the angle of
elevation the ladder forms with the ground?
A. 44.4
B 54.5
C. 35
D. 45.6
Answer:
45.6Step-by-step explanation:
The set up is right angled
Length of the ladder = Hypotenuse = 35ft
Height of window = opposite = 25ft
Using SOH CAH TOA
sin theta = opp/hyp
sin theta = 25/35
sin theta = 5/7
theta = arcsin(5/7)
theta = arcsin()0.7143)
theta = 45.6
Hence the angle of elevation is 45.6
A store called Surfmania sells a $170 surfboard for 30% off. Another store, Coolwaves, advertises the same $170 surfboard for 10% off, but then offers to reduce that sale price by 20%. Which store has the better deal, and what is the savings compared to the other store? Surfmania, $3.40 in savings Surfmania, $3.40 in savings Surfmania, $5.60 in savings Surfmania, $5.60 in savings Coolwaves, $3.40 in savings Coolwaves, $3.40 in savings Final prices are the same. Final prices are the same.
Answer:
Surfmania, $3.40 in savings
Step-by-step explanation:
First, find the price with Surfmania:
170(0.7)
= 119
Find the price with Coolwaves now:
170(0.9)
= 153
153(0.8)
= 122.4
Now, find the amount in savings:
122.4 - 119
= 3.4
So, Surfmania has the better deal with $3.40 in savings.

Answer:
x=11
Step-by-step explanation: since all the angles in the triangle equal 180, you take the angle you already have, 76, But because the sides are equal, the angle adjacent to the 76 is also 76. Now you add 76 and 76, 152, then you subtract that from 180, which is 28. You now take the 28 and put it equal to the 3x-5 and solve for x.

$250 is invested into an account that earns 5 ½ % simple interest for 10 years. What is the account total?
Answer:
$387.50
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year,
then, solving our equation
I = 250 × 0.055 × 10 = 137.5
I = $ 137.50
The simple interest accumulated
on a principal of $ 250.00
at a rate of 5.5% per year
for 10 years is $ 137.50.

Complete the remainder of the table for the given function rule: y = 4 - 3 -4 0 4 8 12 0 0 y7 4 [?]
Answer:
1, -2, -5
Step-by-step explanation:
To find the y value when given x, simply replace the x in the equation with the number given.
X = 4
y = 4 - [tex]\frac{3(4)}{4}[/tex] = 4 - 12/4 = 4 - 3 = 1
x = 8
y = 4 - [tex]\frac{3(8)}{4}[/tex] = 4 - 24/4 = 4 - 6 = -2
x = 12
y = 4 - [tex]\frac{3(12)}{4}[/tex] = 4 - 36/4 = 4 - 9 = -5
