Answer:

9x²29x28 = 0

The answer is 211932=0

9x2 - 29x - 28 = 0

The answer is 29x=−10

Step-by-step explanation:

The question focuses on indices. Start by factorization of 162 and 32. Simplifying 32 yields 2^5 and 162 gives 3^4×2. Simplify the two expressions using the factors. Use the indices rule implying: b√a^c =a^(c⁄b)

∜162+3∜32

162= 81×2=3^4 ×2

32 = 2^5 = 2^4 ×2

∜(2×3^4 )+3∜(2^4×2)=∜(3^4 ) ∜2+3∜2^4 ∜2

3^(4⁄4)× ∜2+3×2^(4⁄4)×∜2 = 3×∜2+3×2∜2

3∜2+6∜2 = ∜2×(3+6) = 9∜2

= 9∜2

Answer:

I think the answer is c.CB

Answer:

x-x=29 answer is equal to 28and

The value at intercept C(1) is 95.68 pounds

The estimated per capita consumption in the year 2010 will be 115.6 pounds

Part a:

Per capita consumption of all the poultry in a country is given by the function C(x) = 2.49x + 93.19

Finding intercept C(1):

For C(1) the value of x will be 1

C(1) = 2.49(1) + 93.19

C(1)  = 95.68

Hence, the value at intercept C(1) is 95.68 pounds

Part b:

Finding the per capita consumption in the year 2010:

where x will be 9, as the time period from 2001 to 2010 is 9 years

C(2010) = 2.49(9) +93.19

= 22.41 + 93.19

= 115.6

Hence, the estimated per capita consumption of all the poultry in the country will be 115.6 pounds in the year 2010

We need to know about unitary method to solve the given question. Option () is correct, Recycling Center A processes aluminium faster; Recycling Center B's rate is about 24 pounds per hour.

Unitary method is a method to find out the value for a single quantity and then derive the value for the asked quantity. Here is this question we know Center A processes aluminium at a rate of 100 pounds per hour and center B processes  2 tons per week, we need to know who processes aluminium faster. To find the answer we need to first find how much aluminium center B processes per hour, to find that we need to use unitary method.

1 ton=2000 pounds

so, 2tons=2x2000=4000 pounds

Thus Center B processes 4000 pounds per week

A day has 24 hours, a week has 7 days, we know that the centers operate all day every day so number of hours in a week is

7x24=168 hours

Center B processes 4000 pounds in 168 hours

Center B processes 4000/168 pounds in one hour

Center B processes about 24 pounds in one hour

Therefore, we can see that Center A processes aluminium faster and Center B's rate is about 24 pounds per hour, thus option (2) is right.

The required amount of shipping paid by Mai is 8.

In mathematics, a percent is a number or ratio expressed as a fraction of 100. It is often denoted using percentage sign "%".

Now it is given that,

Amount of shipping fee = 7.95

percentage of shipping fee = 6.25% of the total purchase

Total amount purchased = 128

Thus, amount of shipping for this purchase is given as,

Amount of shipping = 6.25% of 128

Solving,

Amount of shipping = 0.0625*128 = 8

Since the shop charges shipping fees of whichever is greater

and 7.95 < 8

Thus, amount of shipping paid by Mai = 8

Answer:2.7 - 1.1 = 1.6

Answer:%

Step-by-step explanation:

The length of ribbon that remained is 3m and 90 cm which is calculated by subtracting the cut length from the total length of the ribbon.

An arithmetic operation called subtraction simulates the process of removing items from a collection.

Subtraction can mean eliminating or lowering physical and abstract quantities utilizing a variety of things, such as negative integers, fractions, irrational numbers, vectors, decimals, functions, and matrices, however it is typically linked with natural numbers in mathematics.

The total length of the ribbon is is 5 meters or 500 centimeters. The length of the piece of ribbon that was cut is 1 m 10 cm=110 cm.

Length of the ribbon that remained is calculated by subtracting the total length form the cut off length 500-110 = 390 centimeters.

390 centimeters= 3 meters and 90 centimeters.

So the length that remained is 3 meters and 90 centimeters.

the measure of angle A is 96° when A and B are vertical angles.

We are given the two vertical angles as:

A = (4x − 4)° and B = (5x – 29)°

We know that, vertical angles are equal to each other.

So, we get that:

4 x - 4 = 5 x - 29

5 x - 4 x = 29 - 4

x = 25

A = 4 x - 4

A = 4 ( 25 ) - 4

A = 100 - 4

A = 96°

Given the dimensions of the shape, the length of PR can be found to be 19.8 units.

The given triangle is an equilateral triangle which means that all the sides are equal.

That then means that:

PR = QR

So we can solve as:

2n + 9 = 7n - 18

Solving for n gives:

7n - 2n = 18 + 9

5n = 27

n = 5.4

The length of PR is therefore:

B. It decreases.

C. It stays the same.

The correct way of using the equation is:

$25,475 = (1 - m)*$27,000

And with that we will get that the markdown is of the 5.6%

We know that the original price of the car is $27,000, and there is a markdown such that the new price of the car is $25,475.

Then, if m represents the markdown, we can write the equation:

$25,475 = (1 - m)*$27,000

Now we can solve this for m to get:

1 - $25,475/$27,000 = m = 0.056

If we want this in percentage form, we need to multiply it by 100%.

0.056*100% = 5.6%
