Answer:

<h2>0</h2>

Step-by-step explanation:

x^3 \times y^4\\\\x = 3\\y =0 \\\\(3)^3\times 0^4\\\\3^3\times\:0^4\\\\\mathrm{Apply\:rule}\:0^a=0\\0^4=0\\\\=3^3\times\:0\\\\\mathrm{Apply\:rule}\:0\times\:a=0\\=0

Answer:

We need to calculate x^3*y^4 for x = 3 and y = 0.

First thing we do is replacing x and y on x^3*y^4:

3^3*0^4

Now, we only need to solve it:

3^3*0^4 = 27 * 0 = 0

Remember that 3^3 = 3*3*3

Subtract the equations straight down. So we'll subtract the x terms together
5x - 5x = 0x = 0 
meaning the x terms effectively go away after subtraction

Then we do the y terms together in the same exact order
y-3y = -2y

Then finally the right hand side values
6 - (-5) = 6+5 = 11

All of that work done indicates we have 0x-2y = 11 which is the same as -2y = 11. Divide both sides by -2 and we end up with y = -11/2

This answer isn't listed so I'm thinking there's a typo your teacher made somewhere.

Match the real-world problem to its constant of proportionality.
FrozenT [24]

Real word problem ⇒ constant of proportionality

$4.16 for 4 pounds of bananas ⇒ 1.04

$16.48 for 8 pounds of potatoes  ⇒ 2.06

$18.36 for 2 pizzas  ⇒ 9.18

2 cups of flour to make 36 cookies ⇒ 18

<em><u>Solution:</u></em>

A proportional relationship is one in which two quantities vary directly with each other.

We say the variable y varies directly as x,

if for x ∝ y

then,  x = y k

Where "k" is called constant of proportionality

k = \frac{x}{y}

<em><u>$4.16 for 4 pounds of bananas</u></em>

x = 4.16 and y = 4

k = \frac{4.16}{4} = 1.04

Thus constant of proportionality is 1.04

<em><u>$16.48 for 8 pounds of potatoes</u></em>

x = 16.48 and y = 8

k = \frac{16.48}{8} = 2.06

Thus constant of proportionality is 2.06

<em><u>$18.36 for 2 pizzas</u></em>

x = 18.36 and y = 2

k = \frac{18.36}{2} = 9.18

Thus constant of proportionality is 9.18

<em><u>2 cups of flour to make 36 cookies</u></em>

x = 36 and y = 2

k = \frac{36}{2} = 18

Thus constant of proportionality is 18

When the new computer lab opened there were 18 computers.by the end of firdt week there were 25 computers. Find the percent of c
aliina [53]

The number of computers increased by 38.9%

Step-by-step explanation:

Number of computers at start of week = Old value = 18

Number of computers by end of week = New value = 25

Change = New value - Old value

Change = 25-18 = +7

The positive sign indicates the increase.

Increase percent = \frac{Change}{Old\ value}*100

Increase\ percent=\frac{7}{18}*100\\\\Increase\ percent=\frac{700}{18}\\\\Increase\ percent= 38.88\%

Rounding off to nearest tenth

Increase percent = 38.9%

The number of computers increased by 38.9%

Keywords: difference, percentage
