My teacher says the answer is not 140 or 90

Answer:

down below.

Step-by-step explanation:

20 × 400 = 8000

8000 - 7200 = 800

therefore the % mark up is 10%, because 10% of 8000 is 800.

800 + 7200 = 8000

Answer:

the answer is 11%

Step-by-step explanation:

hit me with praise and love this answer HAHA your welcome

A) The dimensions are (x+10) by (x+10).

B) The perimeter is given by 4x+40.

C) The perimeter when x is 4 is 56.

The quadratic can be factored by finding factors of c, the constant, that sum to b, the coefficient of x.  Our c is 100 and our b is 20; we want factors of 100 that sum to 20.  10*10=100 and 10+10=20, so those are what we need.  This gives us (x+10)(x+10 for the factored form.  

Since the dimensions are all (x+10), and there are 4 sides, the perimeter is given by 4(x+10).  Using the distributive property we have 4*x+4*10=4x+40.

To find the perimeter when x=4, substitute 4 into our perimeter expression:

4*4+40=16+40=56.

Answer:

A) The dimensions are (x+10) by (x+10).

B) The perimeter is given by 4x+40.

C) The perimeter when x is 4 is 56.

Answer:

The data is a random sample from the population of interest and The sample size is less than 10% of the population size. ( b )

Step-by-step explanation:

roasted beef protein = 20 grams  ( mean value )

sample size of soybean compound = 5

mean value of their protein = ( 15 + 22 + 17 + 18 + 23)  / 5 = 19

The conditions that have been met are :

The data is a random sample from the population of interest. and

we can say the sample size is less than 10% of population size because we do  know the population size is a large supply

Answer:

  sin(θ) = -12/13

Step-by-step explanation:

The distance from the origin to the given point is ...

  r = √(5² +(-12)²) = √169 = 13

For point (x, y) ⇔ (r; θ), recognize that (x, y) = (r·cos(θ), r·sin(θ)). This translates to ...

  sin(θ) = y/r

  sin(θ) = -12/13

Answer: 2

Step-by-step explanation:

2+2+1+3=8/4=2

Answer:

In two or more complete sentences, describe the transformation(s) that take place on the parent function, f(x)… ... parent function, f(x) = log(x), to achieve the graph of g(x) = log(-2x-4) + 1. 2 ... Re-write the transformed function by taking -2 common,. Step 1 -. Shift 2 unit left i.e, f(x)→f(x+b) shifting left by b unit.

12 because imagine 40 / 3  ok?   now what makes 160 40 x 4    so you do that for the button 4 x 3 please put heart

Answer:

V= 8

x=4.5

BCF =48 CFE=132

V=352.8 =8.4x8.4x5

For the volume one i cant read the number but if the bottom number is 8 then V=803.84

if its 6 then v = 452.16

Step-by-step explanation:

v= 2x2x2 v = 8

x is 11x-9=7x+9 | 4x=18 | x=4.5

15x=180 x=12 | CFE = 11x12=132 | BCF = 4x12=48

Answer:

m=0

Step-by-step explanation:

3-3/21-8

0/21-8

0/13

0

Answer:

(8, 3) (21, 3)

slope = change in y divided by change in x

slope = (3 - 3) / (21 -8)

slope = 0 / 13

slope = 0

Answer:

B

Step-by-step explanation:

7x + 1 isn't equal to 8x

For example:

Addition. In this equation, you can add all of the coefficients (2, 5, and 4) because the variables are the same (a).

2a + 5a + 4a = 11a

Subtraction. In this equation, you can subtract all of the coefficients (11, 5, and 4) because the variables are the same (a).

11a – 5a – 4a = 2a

Answer:

[tex] \frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7} [/tex]

Step-by-step explanation:

Given:

S = 52.5°

s = QR = 7

Q = 80°

q = RS = ?

Required:

Equation that could be used to find the length of RS

Solution:

We would need the law of Sines which is given as:

[tex] \frac{Sin(A)}{a} = \frac{Sin(B)}{b} = \frac{Sin(C)}{c} [/tex]

Applying the Law of Sines, we would have the following equation:

[tex] \frac{Sin(Q)}{q} = \frac{Sin(S)}{s} [/tex]

Plug in the values

[tex] \frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7} [/tex]

Therefore, the equation that can be used to determine the length of RS is [tex] \frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7} [/tex]

Answer:

  1.  monthly: 0.25%; quarterly: 0.75%

  2.  monthly: ≈ 0.45833%; quarterly: 1.375%

Step-by-step explanation:

In each case, the base of the exponential term is the annual growth factor. The annual growth rate (interest rate) is ...

  growth rate = growth factor - 1

Then the monthly rate is ...

  monthly rate = growth rate/12

and the quarterly rate is ...

  quarterly rate = growth rate/4

__

1. monthly rate = (1.03 -1)/12 = 0.03/12 = 0.0025 = 0.25%

  quarterly rate = (1.03 -1)/4 = 0.03/4 = 0.0075 = 0.75%

__

2. monthly rate = (1.055 -1)/12 = 0.055/12 ≈ 0.0045833 = 0.45833%

  quarterly rate = (1.055 -1)/4 = 0.055/4 = 0.01375 = 1.375%

Answer:

[tex]x^3+8x^2+2x+1[/tex]

Step-by-step explanation:

Combine like terms (terms with the same exponent).

[tex]x^3+(3x^2+5x^2)+(x+x)+1=x^3+8x^2+2x+1[/tex]

"Standard form" means to list terms so the exponents go from high to low (descending order).

Answer:

12:19

Step-by-step explanation:

To create a ratio, we compare a portion to a whole. In this case our portion is 12 strawberries. Our whole is the total fruit, so let's add up each fruit to find the total.

12 + 3 + 4 = 19

Now we have our portion (12) and our total (19).

Let's create a ratio.

12:19

This ratio cannot be simplified further, so that is your answer.

Hope this helps!

Answer:

0.2693

Step-by-step explanation:

Thus is a binomial probability problem :

p = 0.36

1 - p = 0.64

n = 9

x = 3

Using the binomial probability relation :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

P(x = 3) = 9C3 * 0.36^3 * 0.64^6

P(x = 3) = 84 * 0.36^3 * 0.64^6

P(x = 3) = 0.2693

Answer:

[tex]\{\frac{1}{8},\frac{1}{4},\frac{1}{2}\}[/tex]

Step-by-step explanation:

Required

Which is ordered in ascending order

To do this, it is best to convert the fractions to decimal and then make comparison.

From the options, only (b) is ordered in ascending order and the proof is as follows.

[tex]\{\frac{1}{8},\frac{1}{4},\frac{1}{2}\}[/tex]

Convert to decimals

[tex]\{0.125, 0.25, 0.5\}[/tex]

By comparison:

[tex]0.125< 0.25< 0.5[/tex]

Hence, (b) is ordered from least to greatest
