You want your answer in the form of ¢/oz so

$1.59(100¢/$)/10oz

15.9¢/oz which is approximately

≈16¢/oz in words

16¢ per ounce

How many distinct triangles can be formed for which m∠X = 51°, x = 5, and y = 2? zero one two
Vitek1552 [10]
From the law of sines, we have:

\displaystyle{ \frac{\sin \angle X}{x}= \frac{\sin \angle Y}{y}, 

where x and y are the sides opposite to angles X and Y, respectively.


Substituting the known values, we have:



\displaystyle{ \frac{51^{\circ}}{5}= \frac{\sin \angle Y}{2}, thus

                           \displaystyle{ \sin \angle Y=\frac{\sin 51^{\circ}}{5}\cdot2\approx \frac{0.777}{5}\cdot2=0.31.


Using a calculator, we can find that arcsin(0.31)=18 degrees, approximately.

We know that sine of (180-18)=162 degrees is also 0.31. But 162 and 51 degrees add up to more than 180 degrees.

Thus, there is only one triangle that can be formed under these conditions.

Kate made 4 dresses with 7 yards of fabric. how many yards did she use on 1 dress
Ksju [112]
This is a fraction equal to
7 yards ÷ 4 dresses

We want a unit rate where
<span>1 is in the denominator, </span>
so we divide top and bottom by 4.

7÷4= 1.75
_
4÷4=1.
Therefore, Kate used 1.75 yards per one dress (1.75 yds. p/ d)

Hope I helped! :)

If A is a 5 by 7 matrix, what is the maximum rank that A can have?
amm1812

Answer:

5

Step-by-step explanation:

Remember, the rank of a matrix is the number of pivots or number of rows different of zero in the echelon form of the matrix.

Then, if A is a matrix 5\times 7 the maximum number of pivots that can have is one by row, that is, 5.

Then the maximum rank that A can have is 5.

8 is not a factor of 36.... Your answer doesn't work.
m_a_m_a [10]
Correct :)

36 is not divisible by 8.

The prime factorization of 36 is 2*2*3*3

To get 8 we need 2*2*2 but we don't have enough 2's.
