Answer:
$42.88
Step-by-step explanation:
Let's create a proportion using the following setup:
cost/pounds=cost/pounds
We know that it costs $20.42 for a 10 pound turkey.
$20.42/10 pounds= cost/pounds
We don't know how much a 21 pound turkey costs, so we can say that it costs $x for a 21 pound turkey.
$20.42/ 10 pounds= $x/ 21 pounds
20.42/10=x/21
We want to find x, by getting x by itself.
x is being divided by 21. The inverse of division is multiplication. Multiply both sides by 21.
21*(20.42/10)=(x/21)*21
21* 20.42/10=x
21*2.042=x
42.882=x
Round to the nearest cent, or hundredth.
42.88=x
x= $42.88
A 21 pound turkey costs $42.88
Answer:
C
Step-by-step explanation:
Using the rule of radicals
× 
⇔ 
Simplifying each radical before combining them.
= 
= 
× 
= 3
-----------------------------------------------------------------------------
= 
= 
× = 5
---------------------------------------------------------------------------
Hence
2(3) - 3(5
= 6 - 15
= - 9 → C
Answer: 50
Step-by-step explanation:
Step 1: 60% = .60
Step 2: 30 = .60Y
Step 3: Divide both sides of the equation by .30 to isolate the variable Y.
30/.60 = .60/.60Y
50=Y
Therefore, 30 is 60% of 50.
Check the slopes
the first 2 points have slope (3-1) / (5-1) = 2/4 = 1/2
points 2 and 3 slope = 4/2 = 2
3 and 4:- slope = -2/-4 = 1/2
4 and 1:- slope = 4/2 = 2
so we have 2 pairs of opposite sides which are parallel
looks like a parallelogram or a rhombus
if adjacent sides are equal its a rhombus
length betwee pts 1 and 2 = sqrt(2^2 + 4^2) = sqrt20
.. ... ... .. .. .. ...2 and 3 = sqrt(4^2 + 2^2) = sqrt20
so it is a rhombus
