Radda [10]3 years ago
3 0

Answer:

5.52

Hope this helped!

Step-by-step explanation:

Let c = cost of a spoon  

3c = cost of knife  

9c + 12(3c) = 82.80  

9c + 36c = 82.80  

c = 82.80/45  

= 1.84  

cost of 1 knife = 1.84 x 3  

= $5.52 check  

9*1.84 + 12*5.52 = 82.80

Micheal just moved here from Chicago. Micheal has red hair, therefore people from Chicago have red hair
Snezhnost [94]

Answer:

inductive

Step-by-step explanation:

Inductive reasoning is based on generalization, and making conclusions without hard evidence. If Micheal has red hair and is from Chicago, inductive reasoning draws the conclusion that everyone in Chicago has red hair. Deductive reasoning would be predicting that everyone in Chicago has red hair, and then testing it to see if you are right.

you sell bracelets for 2$ each and necklaces for 3$ each at a local flea market. you collected 95$, selling a total of 37 jewelr
777dan777 [17]
Use simultaneous equations.
let the number of bracelets be y and necklaces be z.
so
2y + 3z = 95. this is formula 1
y + z = 37. this is formula 2
so from formula 2, we can change that to
y = 37 - z. this is formula 3
sub 3 into 1,
2 (37-z) + 3z = 95
74 - 2z + 3z = 95
z = 21
sub z = 21 into 3,
y = 37 - 21
y = 16
therefore you sold 16 bracelets and 21 necklaces

What is the quotient?
Setler79 [48]

Answer:

Option 3) \frac{1}{(t+4)^{2}}

Step-by-step explanation:

In the given question we have to calculate the quotient after division.

To solve this question we will factorize (t²+7t+12) first and then we will will divide by this.

⇒ t²+7t+12 = ( t²+4t+3t+12)

⇒ t(t+4)+3(t+4)

⇒ (t+3)(t+4)

Now its a simpler form of divisor to get the answer.

We come back to the question

\frac{(t+3)}{t+4}\div(t^{2}+7t+12)

= \frac{(t+3)}{t+4}\div(t+3)(t+4)

Or =\frac{(t+3)}{t+4}\times\frac{1}{(t+3)(t+4)}

=\frac{1}{(t+4)^{2}}

So the right answer is \frac{1}{(t+4)^{2}}
