2 answers:

The variable is x so to make it into function notation just replace y with any letter next to (the variable) in this case x. So the answer is g(x)=2x-7 this isn't the only way, it can be any letter. It can also be t(x)=2x-7. Hope this helps!

I believe it would be f(x)=2x-7

13 is the answer. You would first list the numbers from least to greatest. Then you would find which number is in the middle. But since it would be between 12 and 14, since there is no even middle, you would find the middle of 12 and 14. And 13 is between 12 and 14. Sooooooo....

13 is the answer.

A shopper paid $2.52 for 4.5 pounds of potatoes, $7.75 for 2.5 pounds of broccoli, and $2.45 for 2.5 pounds of pears. what is th

kobusy [5.1K]

Answer:

a) UNIT PRICE of potatoes is $0.56

b) UNIT PRICE of broccoli is $3.1

c) UNIT PRICE of broccoli is $0.98

Step-by-step explanation:

UNIT PRICE is defined as the price of 1 unit.

$\textrm{Unit Price} = \frac{\textrm{Total cost on n products}}{\textrm{n}}$

Now, here in the given question:

1. Cost of 4.5 pounds of potatoes is $2.52

So, the unit price of potatoes $= \frac{\textrm{2.52}}{\textrm{4.5}} = 0.56$

⇒ 1 pound of potatoes cost $0.56

Hence,UNIT PRICE of potatoes is $0.56

2 Cost of 2.5 pounds of broccoli is $7.75.

So, the cost of 1 pound of broccoli $= \frac{\textrm{7.75}}{\textrm{2.5}} = 3.1$

⇒ 1 pound of broccoli cost $3.1

Hence,UNIT PRICE of broccoli is $3.1

3. Cost of 2.5 pounds of pears is $2.45.

So, the cost of 1 pound of pears $= \frac{\textrm{2.45}}{\textrm{2.5}} = 0.98$

⇒ 1 pound of pears cost $0.98

Hence,UNIT PRICE of broccoli is $0.98

The math club needs to raise more than $552. $.50 for a trip to state competition. The club has raise 12% of the funds which is

ratelena [41]

Each of the members must raise at least $69.46.

To start they need to raise $552.50. However, they have already raised 12% of it. They only need to raise 88% of it.

552.50 x 0.88 = 486.2

Divide the remaining amount by 7 to determine how much each individual must raise.

486.2 / 7 = 69.46

This is a pond in the shape of a prism. It is completely full of water

UkoKoshka [18]

Kindly check picture to the question below.

Answer:

150 minutes

Step-by-step explanation:

Volume of prism = height * base area

Height of prism = 1m

Base area = area of a trapezium

Area of trapezium = 0.5(a + b) h

a, b = parallel sides, h= height of trapezium

Area of trapezium = 0.5(1.4+0.6)*2

Area = 0.5(2)*2 = 2m²

Hence,

V of prism = area of trapezium * height of prism

Volume = 2m² * 1m = 2m³

Decrease in water level due to pumping

20cm decrease in 30minutes

(20/100)m in 30 minutes

0.2 m decrease in height of water

Hence, height of water in prism after 30 minutes pumping :

height - 0.2 = 1 - 0.2 = 0.8m

Volume after 30 minutes of pumping :

Base area * new height

2m² * 0.8m = 1.6m³

Decrease in volume over 30 minutes :

(Initial volume - volume after pumping)

2m³ - 1.6m³ = 0.4m³

If ;

0.4m³ = 30 minutes

1.6m³ = x

0.4x = 48

x = 48 / 0.4

x = 120

Hence, it takes 120 minutes for the remaining 1.6m³ to be emptied.

Hence, total wait time :

120 minutes + 30 minutes

= 150 minutes
