Answer:

No

If the fraction is an improper fraction, the product would be higher

if the numerator of the fraction is smaller than the denominator, the product would be lower

2 x 3/4 = 3/2 = 1 1/2

2 x 4/3 = 8/3 = 2 2/3

Step-by-step explanation:

an improper fraction is a fraction in which the numerator is greater than the denominator

The numerator is the number above. While the denominator is the number below

an example of a fraction = \frac{4}{5}  

4 is the numerator while 5 is the denominator

1. r - 29 = -2r + 19
Sphinxa [80]

Answer: r=16

Step-by-step explanation:

r-29=-2r+19

r=−2r+19+29

r=−2r+48

r+2r=48

3r=48

r=48/3

r=16

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)

Use the Law of Cosines to find the missing angle. In triangle JKL, j=3in., k=4in., and l=2.89., find mJ
slega [8]
Using the law of cosine for Triangle KJL, we can write:

j^{2} = k^{2} + l^{2}-2(k)(l)cos(J)  \\  \\ 
2(k)(l)cos(J)=k^{2} + l^{2}- j^{2} \\  \\ 
cos(J)= \frac{k^{2} + l^{2}- j^{2}}{2(k)(l)}

Using the values of k,j and l, we can write:

cos(J)= \frac{ 4^{2} + (2.89)^{2} - 3^{2} }{2(4)(2.89)}  \\  \\ 
cos(J)= 0.664 \\  \\ 
J= cos^{-1}(0.664) \\  \\ 
J=48.39

Rounding to nearest integer, the measure of angle J will be 48 degrees.
So option B gives the correct answer

Which expression is equivalent to 9^-2?<br> O-81<br> O-18<br> O1/81<br> O1/18
kherson [118]

Answer:

Option C - 1/81

Step-by-step explanation:

9^(-2) = 1/(9^2) [ Because a^(-m) = 1/(a^m) ]

so, 1/(9²) = 1/81.

Hope this helps you.
