x is greater than or equal -3 and less than 5
use x only once in your inequality
Answer:
-3 <= x < 5
Step-by-step explanation:
Because x is less than 5, we put a less than sign. And x is greater than or equal to -3, so we have to put that specific sign.

Answer:
x = 37DG = 22AG = 44AD = 66Step-by-step explanation:
We presume your "centroid ratio theorem" tells you that AG = 2·DG, so ...
(x+7) = 2(x -15)
x + 7 = 2x - 30 . . . . eliminate parentheses
37 = x . . . . . . . . . . .add 30-x
Then AG = 37+7 = 44
and DG = 37-15 = 22.
Thus, AD = AG +GD = 44 +22 = 66

Hey there!
Assuming you meant….

= 0.008 * 0.0081
= 0.0000648
≈ 0.000065
Therefore, your answer should be:

54. Given that P is a positive number, N is a negative
number, and | P | > | N |, which of the following
expressions has the greatest value?
Answer: Choice G [tex]\left| \frac{p-n}{n} \right|[/tex]
============================================================
Explanation:
Pick a positive number for p, and a negative value for n. Make sure that p is further away from 0 than n is (so that [tex]|p| > |n|[/tex] is a true statement).
I'll go for these values
p = 5n = -2Replace every copy of p with 5, and replace every copy of n with -2. Then evaluate or simplify. Use your calculator if needed.
Let's start with choice F.
[tex]F = \left| \frac{p-n}{p} \right|\\\\F = \left| \frac{5-(-2)}{5} \right|\\\\F = \left| \frac{5+2}{5} \right|\\\\F = \left| \frac{7}{5} \right|\\\\F = \left| 1.4 \right|\\\\F = 1.4\\\\[/tex]
Now onto choice G
[tex]G = \left| \frac{p-n}{n} \right|\\\\G = \left| \frac{5-(-2)}{-2} \right|\\\\G = \left| \frac{5+2}{-2} \right|\\\\G = \left| \frac{7}{-2} \right|\\\\G = \left| -3.5 \right|\\\\G = 3.5\\\\[/tex]
Next up is evaluating the expression for choice H.
[tex]H = \left| \frac{p+n}{p-n} \right|\\\\H = \left| \frac{5+(-2)}{5-(-2)} \right|\\\\H = \left| \frac{5-2}{5+2} \right|\\\\H = \left| \frac{3}{7} \right|\\\\H \approx \left| 0.4286\right|\\\\H \approx 0.4286\\\\[/tex]
Then let's compute expression J.
[tex]J = \left| \frac{p+n}{p} \right|\\\\J = \left| \frac{5+(-2)}{5} \right|\\\\J = \left| \frac{5-2}{5} \right|\\\\J = \left| \frac{3}{5} \right|\\\\J = \left| 0.6 \right|\\\\J = 0.6\\\\[/tex]
Lastly, compute expression K.
[tex]K = \left| \frac{p+n}{n} \right|\\\\K = \left| \frac{5+(-2)}{-2} \right|\\\\K = \left| \frac{5-2}{-2} \right|\\\\K = \left| \frac{3}{-2} \right|\\\\K = \left| -1.5 \right|\\\\K = 1.5\\\\[/tex]
-----------------------------------
To summarize, when plugging p = 5 and n = -2 into each expression, we got these results:
F = 1.4G = 3.5H = 0.4286 (approximate)J = 0.6K = 1.5Expression G leads to the largest output.
Therefore, [tex]\left| \frac{p-n}{n} \right|[/tex] has the largest value when p > 0 and n < 0.
The expression |(p-n)/n| has the greatest value. Therefore, option G is the correct answer.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
Given that, p is a positive number, n is a negative number, and |p| > |n|.
Let us consider p=5 and n=-2
Now,
F) |(p-n)/p|
= |(5-(-2))/5|
= |7/5|
= 1.4
G) |(p-n)/n|
= |(5-(-2))/(-2)|
= |7/(-2)|
= 3.5
H) |(p+n)/(p-n)|
= |(5-2)/(5-(-2))|
= |3/7|
= 0.43
J) |(p+n)/p|
= |(5-2)/5|
= |3/5|
= 0.6
K) |(p+n)/n|
= |(5-2)/2|
= |3/2|
= 1.5
The expression |(p-n)/n| has the greatest value. Therefore, option G is the correct answer.

Consider the following statistic. as of january 2009, the usa has produced 60,000 metric tons of nuclear waste in 60 years of operating 104 nuclear power plants. on average, how much waste is produced by each plant on a monthly basis? 0.8 tons per month 83.3 tons per month 104 tons per month 866.3 tons per month
Using proportions, it is found that the average waste produced by each plant on a monthly basis is of 0.8 tons per month.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, there is a period of 60 x 12 = 720 months, with 104 plants, and 60,000 tons of waste were produced, hence the average is given by:
A = 60000/(720 x 104) = 0.8 tons per month.

Which math sentence can be used to determine if this triangle is a right triangle? A triangle has side lengths 12, 15, 18. 12 + 15 = 18 12 squared + 15 squared = 18 squared 12 + 18 = 15 12 squared + 18 squared = 15 squared
Answer:
12^2 + 15^2 = 18^2
Step-by-step explanation:
If we have 3 sides of a triangle we can use the Pythagorean theorem to determine if the triangle is a right triangle
a^2 + b^2 = c^2
12^2 + 15^2 = 18^2
If this is true, then the triangle is a right triangle

when x = 0, y = 40
therefore you can pick either A or D only.
while x increases, y decreases, that's negative relation
so, answer is D
Answer:
Option D
Step-by-step explanation:
y = mx + b
b is the y - intercept (when x = 0):
this graph doesn't show any negative values on the axis so options B and C can't be true since it they have - 40 when its positive 40
y = mx + 40

The daffodils flower Pate needs is 8, total number of flower when rose is 2, is 18 and the carnations to be needed for decoration is 15.
What is algebraic expression?Algebraic expression are the expression which consist the variables, coefficients of variables and constants.
The algebraic expression are used represent the general problem in the mathematical way to solve them.
Pete is making decorations for a dinner party. The instructions tell him to use 9 flowers for a medium-sized decoration which has 2 lilies, 1 rose, 3 carnations, 2 daffodils and 1 iris.
The ratio of daffodils to total flower is,
n=2/9.
To make a large decoration, Pete uses 36 flowers. Let suppose the daffodils flower he needs for this is x. Thus,
x=36*(2/9)
x=4*2
x=8
The rose flower is increased from 1 to 2. Thus, the total number of flower also be twice for decoration.
Flower=2*9
Flower=18
Now Pete uses 10 lilies instead of 2 which is 5 times the medium-sized decoration. Thus, the carnations to be needed is,
Carnations=3*5
Carnations=15
Hence, the daffodils flower Pate needs is 8, total number of flower when rose is 2, is 18 and the carnations to be needed for decoration is 15.

I need help wit part b
Answer:
4a) $26.5 because if x represents how many feet then the slope would be the price of one glulam beam.
4b) $63,600
Step-by-step explanation:
To find the answer to 4b we need to alter the equation we were given. Since x represents how many feet we buy we put 2400 in place of x.
y = 26.5 x 2,400
and we simply solve from here
y = 63,600
So, 63,600 is how much we would be spending for 2400 feet of beams. Hope this helps!!
