Section 1:
using this format we can determine what the answer is:
42 105
—— • ——-
100 x
(the spacing may be off but imagine two separate fractions)
first multiply 100 by 105 to get 10,500
then divide by 42 to get 250
this means that sasha’s book has 250 pages
section b:
using the same formula we can solve this problem:
first we need to multiply 250 by 2 to get the total cost of both tickets
175 x
—— • ——
100 500
(again spacing may be off but think of two separate fractions)
then multiply 500 by 175 to get 87,500
then divide by 100 to get 875
to find the profit subtract 875-500
this means he will make $375 profit
conclusion:
sasha’s book has 250 pages
trevor will make $375 profit
this is the method my teacher taught me last year so it should be right, hope this helps and please mark brainliest!!
Answer:
see below
Step-by-step explanation:
-1/2 * (6x + 10) = 13
Distribute -1/2
–3x – 5 = 13
Add 5 to each side
-3x-5+5 = 13+5
–3x = 18
Divide each side by -3
-3x/-3 = 18/-3
x = -6
Answer:
8x²+14x-15
Step-by-step explanation:
that the right answer
By applying the trigonometry ratio, SOH, the angle that the ladder makes with the building is calculated as: 17.5°
<em><u>Recall:</u></em>
- Trigonometry ratios that can be used to solve a right triangle are: SOH CAH TOA.
- SOH represents: sin ∅ = Opp/Hyp
- CAH represents: cos ∅ = Adj/Hyp
- TOA represents: tan ∅ = Opp/Adj
The diagram attached below depicts the problem given.
∅ = x
Opp = 15 ft
Hyp = 50 ft
- Thus, applying the trigonometry ratio, SOH, we have:
sin x = 15/50
x = 
x = 17.5°
In conclusion, by applying the trigonometry ratio, SOH, the angle that the ladder makes with the building is calculated as: 17.5°
