how do find the area

The equation of the sleeping bag is a linear equation

The ordered pair that does not belong is (74,66)

The equation is given as:

y = x + 8

Subtract x from both sides

y - x = 8

This means that the difference between the y and the x values is 8.

From the list of options, we have:

72 - 64 = 8

78 - 70 = 8

80 - 72 = 8

66 - 74 = -8

The difference between 66 and 74 is -8.

Hence, the ordered pair that does not belong is (74,66)

Answer:

first option

Step-by-step explanation:

x² - 8x = 3

to complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 4)x + 16 = 3 + 16

(x - 4)² = 19 ( take square root of both sides )

x - 4 = ± [tex]\sqrt{19}[/tex] ( add 4 to both sides )

x = 4 ± [tex]\sqrt{19}[/tex]

then

x = 4 - [tex]\sqrt{19}[/tex] , x = 4 + [tex]\sqrt{19}[/tex]

Step-by-step explanation:

14 / 20 x 100 / 1equal to 42

The element is remaining after 18 minutes with the rate of decaying of 26.8 % is 2.99 grams.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

An element with a mass of 820 grams decays by 26. 8% per minute.

Then the mass remaining after one minute will be

Remaining = 100 - 26.8

Remaining = 73.2 %

The element is remaining after 18 minutes will be

Mass = 820 × (0.732)¹⁸

Mass = 820 × 0.00364

Mass = 2.985

Mass ≈ 2.99

The element is remaining after 18 minutes is 2.99 grams.

Answer:

27.25408 grams

Step-by-step explanation:

For each year, we subtract 8% of the sugar content. Therefore, for the first year, we subtract 8% from the original sugar content of 35 to get

sugar content - 8% of the sugar content = 35 - 8% of 35 = 35 - 0.08 * 35 = 1 * 35 - 0.08 * 35 = 0.92 * 35. It can therefore be concluded that subtracting 8% of the sugar content is the same as multiplying the current sugar content by 0.92. We do this every year, so the second year is (0.92 * 35) * 0.92 and the third year is ((0.92 * 35) * 0.92) * 0.92 = 27.25408 grams

A pattern develops, and that is that we multiply by 0.92 each year. Therefore, for x years, we multiply by 0.92 x times or 0.92ˣ as a whole. Therefore, our equation can be written as 0.92ˣ * original amount = 0.92ˣ * 35

By maxima and minima concept, p = $12.50 gives the maximum revenue as $312.50

Expression to model number of backpacks = -2p + 50

As we know that

Revenue collected = Price of a backpack * Number of backpacks

If price  = $9

Number of backpacks = -2*9+50 = 32

Revenue collected = 9 * 32 = 288

If price  = $10

Number of backpacks = -2*10+50 = 30

Revenue collected = 10*30 = 300

If price = $11

Number of backpacks = -2*11+50 = 28

Revenue collected = 11 *28 = 308

If price = $12

Number of backpacks = -2*12+50 = 26

Revenue collected = 12* 26= 312

If price = $13

Number of backpacks = -2*13+50 = 24

Revenue collected = 13 * 24= 312

Since revenue at p=12 and p=13 is the same, it means by the first derivative principle max revenue will be at an average of  points p=12 and p=13

Average value = (12+13)/2 = 12.5

It says that if we get the maximum value at a point, the function value at the same distance in its neighborhood will be equal.

Revenue at p=12.5:

12.5* [-2*12.5+50] = 312.5

Therefore, p = $12.50 gives the maximum revenue as $312.50.

Answer:

6^-2

Step-by-step explanation:

To answer this, you need to know one basic law of indices:

x^-n = 1/x^n

So here 1/36 is the same as 36^-1.

Then we can simply sqr root 36 to give (6^2)^-1.

When two powers are one in and one out of the brackets, they multiply each other. So here it would be 2*-1, which would give -2.

So the answer is 6^-2.

The new area of the given replica's base is; 6250 m²

We are given;

Area of base of statue = 625 m²

Now, an artist wants to create a replica of the base of statue but in the ratio 1:10.

This means that the area will increase by a factor of 10 as 1 sq.unit of the old area will represent 10 sq. units in the new one.

Thus, new area = 625 * 10

New area of statue = 6250 m²
