<h3>Answer: Rs 25</h3>

Explanation:

Each pencil has a profit of Rs 1.25 since $\text{revenue} - \text{cost} = 5.75 - 4.50 = 1.25$

Multiply that result with 20 to get the final answer shown above in bold.

Answer:

$A) (1.2)^{2} = 1.44$

$B)2^ 3+17-(3\times 4) = 13$

$C)\frac{(9)^2}{(3)^3} = 3$

Step-by-step explanation:

Here, the given expressions are:

A) $(1.2)^{2}$

Solving this, we get

$(1.2)^{2} = 1.2 \times 1.2 = 1.44$

⇒ $(1.2)^{2} = 1.44$

B) $2^ 3+17-(3\times 4)$

Now, solving this, we get

$2^ 3+17-(3\times 4) = (2 \times 2 \times2) + (17 -12)\\=8 + 5 = 13$

⇒ $2^ 3+17-(3\times 4) = 13$

C) $\frac{(9)^2}{(3)^3}$

Simplifying this, we get

$\frac{(9)^2}{(3)^3} = \frac{(9\times9)}{(3 \times 3\times3)} = 3$

⇒ $\frac{(9)^2}{(3)^3} = 3$

Write as a unit rate: 36 gallons to 9 minutes *

Nataly_w [17]

Answer

36/9= 4

Step-by-step explanation:

This is a fraction equal to

36 gallons ÷ 9 minutes

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 9

36 gallons ÷ 9

9 minutes ÷ 9

4 gallons

1 minute

4 gallons

minute

= 4 gallons per minute

Eva is at a sushi restaurant. She ordered 2 pieces of squid for a total of $3.50, 1 piece of eel for $3.25, 3 pieces of tuna for

mixas84 [53]

Answer:

squid, crab, tuna, eel

Step-by-step explanation:

Just make each sushi piece into an equation, then solve it.

For example, for the squid: (s stands for squid)

$2s = 3.5\\ s=1.75$ Divide both sides by 2 to get "s" by itself

Eel: (e stands for eel)

e = 3.25

Tuna: (t stands for tuna)

$3t=6.75\\ t=2.25$ Divide both sides by 3 to get "t" by itself

Crab: (c stands for crab)

$4c=8\\ c=2$ Divide both sides by 4 to get "c" by itself

**Then order from least to greatest**
