See explanation in the photo
Answer:
d
Step-by-step explanation:
im pretty sure the right answer would be 12 and 21 just doesn't look right
If the wheel does one full turn in 180 cm, that means the wheels circumference is 180. The equation for circumference is:
Circumference = (Pi) x Diameter
(Can't find the symbol for pi)
Now plug in the 180 for the Circumference:
180 = (Pi) x D
Divide by Pi:
57.296 = D
ANSWER:
The diameter is 57 cm
Answer:
11 : 44
Step-by-step explanation:
There are 11 6th graders and a combination of 44 7th and 8th graders. Therefore, the ratio is 11 : 44. Hope this helps!
The measures of the angles are sin(x) = -5/√41, cos(x) = 4/√41, sec(x) = √41/4, csc(x) = -√41/5 and cot(x) = -4/5
<h3>How to determine the value of sin and cosine?</h3>
The tangent of the angle is given as:
tan(x) = -5/4
The hypotenuse is calculated as:
Hypotenuse = sqrt([(-5)^2 + (4)^2)
Evaluate the squares
Hypotenuse = ±√41
Given that sin(x) < 0, then
Hypotenuse = √41
The sin is calculated as:
sin(x) = -5/Hypotenuse
So, we have:
sin(x) = -5/√41
The cos is calculated as:
cos(x) = 4/Hypotenuse
So, we have:
cos(x) = 4/√41
The values of the reciprocal ratios are
sec(x) = √41/4
csc(x) = -√41/5
cot(x) = -4/5
Hence, the measures of the angles are sin(x) = -5/√41, cos(x) = 4/√41, sec(x) = √41/4, csc(x) = -√41/5 and cot(x) = -4/5
