If the sum of 37 and 12 x is 286, what is the value of x?
Answer:
x = 20.75
Step-by-step explanation:
37 + 12x = 286 <-- Subtract 37
12x = 249 <-- Divide by 12
x = 20.75

Find the missing angles in the diagram below (pls help no links)
Step-by-step explanation:
here you have the answers
A rectangle is 60 cm long and 20 cm wide. Find, to the nearest tenth of a degree, the acute angle formed at the intersection of the diagonals.
Answer:
36.9°
Step-by-step explanation:
As shown in the diagram attached,
θ is the acute angle formed at the intersection of the diagonals of the rectangle.
From the diagram,
tan(θ/2) = 10/30
tan(θ/2) = 1/3
θ/2 = tan⁻¹(1/3)
θ/2 = 18.43
Therefore,
θ = 18.43×2
θ = 36.87
θ = 36.9°
Hence the acute angle formed is 36.9°
Help, and can you show your work?
Step-by-step explanation:
answer A is correct
................
Answer:
c
Step-by-step explanation:
[tex]sin = \frac{opposite}{hypotenuse}[/tex]
it wants us to find sin a
the opposite of a is 24 and the hypotenuse is 26
so sin A = 24/26
[tex]cos = \frac{adjacent}{hypotenuse}[/tex]
it wants us to find cos a
the adjacent of a is 10 and the hypotenuse is 26
so cos A = 10/26

A company has offices in two different countries. The 125 employees at location A have a mean commute time of 40 minutes and a standard deviation of 15 minutes. The 250 employees at location B have a mean and standard deviation of 35 and 10 minutes, respectively.
Every month, the company takes separate random samples of 20 employees from each location for a survey. Each time, they look at the difference in the mean commute time sampled from each location
Consider the formula: ...
Why is it not appropriate to use this formula for the standard deviation of ...
Choose
A. The samples are not independent of each other.
B. We cannot assume independence for the employees sampled from location A.
C. We cannot assume independence for the employees sampled from location B.
Answer:
B
Step-by-step explanation:
We cannot assume independence for the employees sampled from location A.
It is not appropriate to use this formula for the standard deviation of
A. The samples are not independent of each other.
What is the difference between the sample and the population?The entire group about whom you want to make conclusions is referred to as a population.
The particular group from which you will gather data is known as a sample. The sample size is always smaller than the population as a whole.
We cannot rely on the workers' sampled employees' independence.
Assuming independence based on the 10% condition requires at least 200 employees in the population with a sample size of 20, however, location A only has 125 employees.

x = 47°
Step-by-step explanation:
Since CPD is a straight line, then
133 and x are adjacent angles and supplementary, sum to 180° , then
x + 133° = 180° ( subtract 133° from both sides )
x = 47°

what is the solution to the system? with a graph
y=-x+2
y=3x-1
Answer:
x = 3/4
y = 5/4
Step-by-step explanation:
Step:
Substitute−x+2 for y in y=3x−1:
y=3x−1
−x+2=3x−1
−x+2+−3x=3x−1+−3x(Add -3x to both sides)
−4x+2=−1
−4x+2+−2=−1+−2 (Add -2 to both sides)
-4x = -3
x=3/4
Step: Substitute x into the original equation
y=-3/4 + 2
y=5/4

The Invasion of the Lionfish
What was once just an attractive aquarium fish has recently become one of the biggest menaces in the Atlantic. The lionfish was accidentally introduced into the Atlantic Ocean in the 1990s. Because it has no natural predators, it has adapted quickly to its new home. The lionfish now threatens to destroy native fish populations in the Atlantic, Caribbean, and Gulf of Mexico.
The lionfish spreads quite rapidly. Lionfish spread faster than any other invading species. Experts have called the invasion in the Atlantic the worst marine invasion of all time. The lionfish's success comes from an ability to reproduce all year round. In addition, they are greedy eaters with a fondness for small fish and crustaceans. They will eat anything smaller than they are. Lionfish love the warm waters of the Gulf of Mexico. Since their first sighting, they have rapidly multiplied. In some locations, scientists estimate that lionfish populations exploded by 700 percent between 2004 and 2008 alone.
To combat the invasion, wildlife agencies have sponsored lionfish derbies. In these derbies, local scuba divers are invited to harvest lionfish. In addition, many states offer recipes for preparing and eating lionfish to encourage harvesting. Lionfish have to be handled carefully because of their venomous spines, but they are apparently delicious. Increasing the harvest of lionfish will help. However, scientists estimate that more than a quarter of the population would have to be taken every month to stop the growing population.
The lionfish has targeted our most fragile and important ecosystems. Scientists are working tirelessly to learn as much as they can about this predator. We may never be able to completely remove the threat, but many fishermen and seafood fans are hoping we can figure out how to control it.

Becky borrowed $580.00 from the bank. The loan had a 13.5% simple annual interest rate, and she paid off the bill over 1.5 years. What was the total amount, including interest, Becky paid for the loan?
Answer:
697.45
Step-by-step explanation:
interest for the first year = 13.5 % of 580 = 78.3
for 0.5 year, it will be 78.3 /2 =39.15
1year + 0.5 year = 78.3 + 39.15= 117.45
add that to borrowed amount to get total amount paid
117.45+ 580= 697.45

At a soccer tournament 12 teams are wearing red shirts, 6 teams are wearing blue shirts, 4 teams are wearing orange shirts, and 2 teams are wearing white shirts. For every 2 teams at the tournament, there is 1 team wearing ____
Answer:
For every 2 teams at the tournament, there is 1 team wearing RED SHIRTS
Step-by-step explanation:
Step 1
We add all the teams together
Red + Blue + Orange + White
12 + 6 + 4 + 2
= 24 teams
Step 2
We have 12 red teams.
If we find the ratio of red team to total number of teams
= 12 :24
= 1:2
Therefore, for every 2 teams at the tournament, there is 1 team wearing RED SHIRTS
