Answer:
72 boys=72:40
45 girls=81:45
90 girls=162:90
40 girls=72:40
etc.
Step-by-step explanation:
think of it as fractions
Answer:
= 29.64 to the nearest hundredth
Step-by-step explanation:
The three sides of a right-angled triangle have specific names:
- The hypotenuse (H) is the longest side. It is opposite the right angle.
- The opposite side (O) is opposite the angle in question.
- The adjacent side (A) is next to the angle in question.
The 3 trigonometric ratios are:
For the given triangle we are given the angle and the side that is OPPOSITE to the angle, and need to find the hypotenuse.
Therefore, we would use the trig ratio: 
Substituting the values from the triangle: 
Multiply both sides by : 
Divide both sides by 
: 
Therefore, = 29.63859553...
So = 29.64 to the nearest hundredth
Answer:
Step-by-step explanation:
Compare same to same, make ratios (they look like fractions) cross multiply to solve.
Small/Large
=10/15 = 2/3
2/3 = 12/m
18 = m
2/3 = AB/24
16 = AB
2/3 = 13/WZ
19.5 = WZ
Answer:
4/9
Step-by-step explanation:
The scale factor for the linear dimensions of the ball bearings will be the cube root of the volume scale factor:
k = ∛(1.6/5.4) = 2/3
Then the scale factor for the areas will be the square of this scale factor:
ratio of surface area = (2/3)² = 4/9
_____
The area is the product of two linear dimensions, so its scale factor is the product of the linear dimension scale factors. That is, the scale factor for area is the square of the linear dimension scale factor.
Similarly, volume is the product of three linear dimensions, so its scale factor is the cube of the linear dimension scale factor.
So you just want to find out how many groups of 5 1/2 are in 15 dollars, or just dividing.
15/5.5 = 2.72 dollars
I think you said round to the nearest tenth, so 2.70 dollars.
