I think that the answer is A because you are being asked for the tens place. Since you are looking to identify the place value, choice B and C are automatically eliminated because each place value increases by multiplying by ten. 20 and 60 are not multiples of 10. To identify the tens place, you would have to multiply by ten. I thought of this question in the sense of scientific notations.
Answer:
18 rubber band bracelets
Step-by-step explanation:
1 hour = 4 bracelets
4.5 hours = ?
4.5 hours/× 4 bracelets
_______
1 hour/
4.5×4 bracelets = 18 bracelets
In an hour Jessica makes four bracelets and in 4.5hours she makes how many bracelets ,we don't know , obviously in 4.5hours she would make more so if more less will divide.
so 4.5hours over 1hour times 4 bracelets. so hour will cancel hour and now 4.5 times 4 bracelets is equal to 18 bracelets

x means everything in algebra. It is a variable, which means that its meaning changes based on context. For example, x could be time, but it could also be cars. x is what all Mathematicians chase after and it is also the greatest tool at their disposal. x is generally called an independent variable because its value determines the output of a function. y, on the other hand, is the result of fooling around with x. It's a dependent variable, which means that y changes when x changes.
To have a weight of 2.21N., the ball's mass is (2.21/9.8) = .226kg.
<span>a) d = 1/2 (vt), = 1/2 (18 x .17), = 1.53m. </span>
<span>b) Acceleration of the ball = (v/t), = 18/.17, = 105.88m/sec^2. </span>
<span>f = (ma), = .226 x 105.88, = 23.92N. </span>
Answer:1.56
Step-by-step explanation:
For constant of proportionality of k,
y=(1/k)*x
If y =9,
9=7/k
K=7/9=0.78
y=0.78x
y=0.78*2=1.56
When x
