Step-by-step explanation:

simply multiply 4 to the numbers in the brackets. If there is an unknown variable then write it as it is. Don't forget the to multiply the signs as well.

4 x 1/4a = 1a = a

4 × b = 4b

4 × -6 = -24

Answer:

a + 4b - 24

Step-by-step explanation:

Expand brackets. Each term in the brackets is multiplied by 4.

4( 1/4a) + 4(b) + 4(-6)

the equation y = x + 8 represents the length, y, in inches of a sleeping bag for a person who is x inches tall. which ordered pair does not belong on the graph? (64,72) (70,78) (72,80) (74,66)

Answers

The equation of the sleeping bag is a linear equation

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

How to determine the ordered pair that does not belong

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:

11.776

Step-by -step explanation:

Here we are given a equation which is ,

[tex]\rm\longrightarrow 10^{x-10}-8=51.7 [/tex]

And we would like to solve this using logarithms , so firstly add 8 on both sides , we get ;

[tex]\rm\longrightarrow 10^{x-10}= 51.7+8 [/tex]

Simplify,

[tex]\rm\longrightarrow 10^{x-10}= 59.7 [/tex]

Now take log to the base 10 on both sides ,

[tex]\rm\longrightarrow log_{10}10^{x-10}=log_{10}(59.7) [/tex]

Recall that [tex]log\ m^n = n\ log m [/tex] .So ;

[tex]\rm\longrightarrow (x-10)(log_{10}10=log_{10}(59.7) [/tex]

Again recall that [tex] log_a a = 1[/tex] .So ; here [tex]log_{10}10[/tex] becomes 1 .

[tex]\rm\longrightarrow (x -10)1 = log_{10}59.7 \\ [/tex]

[tex]\rm\longrightarrow (x-10)= log_{10}(59.7)[/tex]

And the value of log 59.7 = 1.7759 . So on substituting this value , we have ;

[tex]\rm\longrightarrow x -10 = 1.7759 [/tex]

Add 10 to both sides ;

[tex]\rm\longrightarrow x = 10+1.7759 [/tex]

Simplify,

[tex]\rm\longrightarrow \underline{\underline{\red{\rm { x = 11.7759 \approx 11.776}}}}[/tex]

Which expressions are equivalent [tex]\frac{1}{36}[/tex]

Answers

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.

A drinks manufacturer is reducing the sugar content of one of their fizzy drinks by 8% per year over the next
3 years.
The sugar content of a standard can is currently 35 grams.
Calculate the sugar content of a standard can after 3 years.

Answers

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

The interest, rate of interest, principal, and period of time are related by the simple interest formula. An unknown value can be found using this formula with the known values filled in.

  I = Prt . . . . interest on principal P at annual rate r for t years

  ₹1222 = P(0.065)(4) . . . . . using the given values

  ₹1222/0.26 = P = ₹4700 . . . . divide by the coefficient of P

The principal that earns the given amount of interest is ₹4700.

A store uses the expression –2p 50 to model the number of backpacks it sells per day, where the price, p, can be anywhere from $9 to $15. Which price gives the store the maximum amount of revenue, and what is the maximum revenue? (Revenue = price mc023-1. Jpg number of backpacks. ) $9. 00 per backpack gives the maximum revenue; the maximum revenue is $32. 0. $12. 00 per backpack gives the maximum revenue; the maximum revenue is $312. 0. $12. 50 per backpack gives the maximum revenue; the maximum revenue is $312. 50. $15. 00 per backpack gives the maximum revenue; the maximum revenue is $20. 0.

Answers

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

What is first derivative principle?

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.

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.

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]
