Max was on vacation twice as long as Jared and half as long as Wesley. The boys were on vacation a total of 3 weeks. How many days was each boy on vacation?

Answers

Lets say W=Wesley, M=Max, and J=Jared.
So your equations are M=2J, 2M=W, and M+J+W=21days(3 weeks)
So substituting M and W into M+J+W=21 gives you 2J+J+2M=21, substitute M again, to get 2J+J+4J=21 so you get 7J=21 so J= 3 days. Using J=3, substitute in to find M, using M=2J, so M=2(3) so M=6 and using that, substitute into 2M=W, so 2(6)=W so W=12. And 12+6+3=21 to check.

Rewrite in order from least to greatest 35% 3/10 37/100 0.305

Answers

Answer: 3/10 -> 0.305 -> 35% -> 37/100

Step-by-step explanation:

Convert it all to the same format. Let's choose decimal.

35% = 0.35

3/10 = 0.3

37/100 = 0.37

0.305 = 0.305

We then rank from least to greatest.

0.3 -> 0.305 -> 0.35 -> 0.37

Then convert back.

3/10 -> 0.305 -> 35% -> 37/100

Answers

distance formula is like pythagoren ahtoerem
D= $\sqrt{(7-2)^(2)+(5-8)^(2)}$
the distance between oints (x1,y1) and (x2,y2) is
D= $\sqrt{(x1-x2)^(2)+(y1-y2)^(2)}$
A=(-3,-1) and (5,2)
D= $\sqrt{(-3-5)^(2)+(-1-2)^(2)}$
D= $\sqrt{(-8)^(2)+(-3)^(2)}$

A right triangle has side length 9,40, and 41 as shown below. Use these lengths t find cos Y, and tan Y, and sin Y.

Answers

Trigonometric functions are applicable to the right-angled triangles. The value of the Sin(Y), Cos(Y), and Tan(Y) are 0.976, 0.219 and 4.445.

What are Trigonometric functions?

$\rm Sin \theta=(Perpendicular)/(Hypotenuse)\n\n\nCos \theta=(Base)/(Hypotenuse)\n\n\nTan \theta=(Perpendicular)/(Base)$

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

Given to us

XY = 41

YZ = 9

XZ = 40

In ΔXYZ for ∠Y,

$\rm Sin \theta=(Perpendicular)/(Hypotenuse)\n\n\rm Sin (\angle Y)=(XZ)/(XY)\n\n\rm Sin (\angle Y)=(40)/(41)\n\n$

$\rm Cos \theta=(Base)/(Hypotenuse)\n\n Cos (\angle Y)=(ZY)/(XY)\n\n Cos (\angle Y)=(9)/(41)$

$\rm Tan \theta=(Perpendicular)/(Base)\n\nTan \theta=(XZ)/(ZY)\n\nTan \theta=(40)/(9)$

Hence, the value of the Sin(Y), Cos(Y), and Tan(Y) are 0.976, 0.219 and 4.445.

Final answer:

The cos Y, sin Y, and tan Y of a right triangle with side lengths of 9, 40, and 41 can be calculated using trigonometric ratios. Cos Y equals 9/41, sin Y equals 40/41, and tan Y equals 40/9.

Explanation:

In a right-angled triangle, we use the concept of trigonometric ratios which involves sine (sin), cosine (cos) and tangent (tan). Here, the side length 9 would be considered the adjacent side (a), the side length 40 would be considered the opposite side (b), and the side length 41 would be the hypotenuse (c).

The trigonometric ratios can be determined as follows:

Cosine (cos) Y = adjacent/hypotenuse = 9/41
Sine (sin) Y = opposite/hypotenuse = 40/41
Tangent (tan) Y = opposite/adjacent = 40/9

This would be the solution to finding the cos Y, tan Y, and sin Y with respect to angle Y.
