T + b = 13...this is the seats....the number of trike seats + bike seats = 13
3t + 2b = 31....this is the wheels....number of trikes with 3 wheels + number of bikes with 2 wheels = 31 wheels
ur answer is A
Answer:
7 to 15, 7:15, 7/15
Step-by-step explanation:
Ratios can be written as:
a to b
a:b
a/b
We want to find the ratio of exercise days to days in the month. She exercises 14 days out of 30 days in the month. Therefore,
a= 14
b= 30
14 to 30
14:30
14/30
The ratios can be simplified. Both numbers can be evenly divided by 2.
(14/2) to (30/2)
7 to 15
(14/2) : (30/2)
7:15
(14/2) / (30/2)
7/15
Possible values for y are<u> infinite</u>
<h3>Further explanation
</h3>
Trigonometry is the science of mathematics that studies the relationship between sides and angles in triangles
Given special angles of trigonometric functions, for example

In the trigonometric function equation y = cos⁻¹ 0, then the value of y can be determined:
y = cos⁻¹0
y = arc cos 0
cos y = 0
Then the value of y :

Or can be formulated :
⇒ y: arithmetic sequence
So there are infinite values for y
