Which expression is NOT equivalent to 8x ?
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
An architect is designing square windows with an area of(x2 + 16x +64) ft?. The dimensions of the
windows are of the form ax +b, where a and b are whole numbers.
Part 1 out of 2
Find an expression for the perimeter of the windows.
The perimeter of the square is represented by
(x+
6 ft.
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.

A department store buys 400 shirts at a cost of $7 200 and sells them at a selling
price of $20 each. Find the percent markup
The percent markup is % round to the nearest whole number as needed) .
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%

A group of nutritionists is hoping to show that a new soybean compound has more protein per gram than roast beef, which has a mean protein content of 20 grams. A random sample of 5 batches of a large supply of soy compound have been tested, producing protein contents of 15, 22, 17, 18, and 23 grams. Which of the following conditions have been met?
I. The data is a random sample from the population of interest.
II. The sample size is less than 10% of the population size.
III. The sample size is large.
a. I only.
b. I and II.
c. I, II and III.
d. II only.
e. III only.
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

exponential function models the annual rate of increase. Find the monthly and quarterly rates
9514 1404 393
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%

Which of the following equations could be solved to determine the length of RS?
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]

Thirty-six percent of U.S. adults have postponed medical checkups or procedures to save money. You randomly select nine U.S. adult. Find the probability that the number of U.S. adults out of the nine who have postponed medical checkups or procedures to save money is exactly 3.
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
If θ is an angle in standard position and its terminal side passes through the point (5,-12), find the exact value of sinθ in the simplest radical form. need answer, please
9514 1404 393
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

Step-by-step explanation:

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

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
Kori has 12 strawberries, 3 pineapples, and 4 kiwis. What is the ratio of strawberries to total fruit?
HELP!
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!
