Francesca is painting a picture of the purple flowers in her garden. She mixes paint to make the perfect color for each type of
aniked [119]

Find total ounces mixed for each flower:

Daisies = 2+5 = 7 ounces

Tulips = 3 +6 = 9 ounces

Now find the ratio of purple to white for each one:

Daisies = 5/7 = 0.714

Tulips = 6/9 = 0.666

Daisies have more purple so would be the darker ones.

Plz help with math thank you

Answer:

Step-by-step explanation:

Law of Sines  recall   Sin(A) /a  = Sin(B) /b  

does the above make sense?

Next we need to find  the angle of A

notice that 16+75=91  :o

so angle A is only 89° ..(b/c all the way around then inside of a triangle is 180)  so this is NOT a right triangle but that's okay, b/c law of sines still works fine.

then we want to find length of line AB

and if 89 = A  then a = BC

and if  75 = B the  b = AB (note that in the given triangle this is angle C, i'm using B , b/c you can see the difference between capital B and  lower case b much easier than you can with C, & c  :/   )

capitals are the angles while lower case are the length of the sides

then

Sin(89) / 29 = Sin(75) / b

solve the parts that can be put into numbers or solve for 'b' first, that means isolate 'b' all by itself on one side of the equal sign .

0.034477 = 0.965925/ b

b = 0.965925 / 0.034477

b = 28.0165

b = 28.0 ( to the nearest 10th)

we have the parts to plug in now

Sin(75) /

Which number is a perfect square?<br> оооо
puteri [66]

Answer:

1, 4, 9, 16, 25, etc

Step-by-step explanation:

a perfect square is a whole number multiplied by itself. it can be written with the notation ^2

to find a perfect square, simply square or bring to the 2nd power, any whole number

for example 9^2

this means that 9 is multiplied by ITSELF 2 times, it is NOT 9*2

it can also be written as 9*9=81

hope this helps, if anything confuses you feel free to ask ♡

Answer:

D. 15

Step-by-step explanation:

Given the expression, 32 + 2n - 9, and a value of <em>n </em>= -4:

You can substitute the value of <em>n</em> into the given expression:

= 32 + 2n - 9

= 32 + 2(-4) - 9

= 32 - 8 - 9

= 15

Therefore, the correct answer is D. 15
