Which one would it be
Answer:
A or [tex]\frac{\sqrt{6} }{2}[/tex]
Step-by-step explanation:
*note- this method only works because the denominator values are being multiplied, if they were being added then there are extra steps to keep in mind but for now this is simple*
Start by dividing the root 12 in the numerator by the root 2 in the denominator
[tex]\frac{\sqrt{12} }{\sqrt{2} }=\sqrt{6}[/tex]
Then we simply substitute back in the 2 (from the denominator) that we ignored for a second to get our answer
[tex]\frac{\sqrt{6} }{2}[/tex]
*note- if you are allowed to use a calculator then you could also plug in your values to check each answer option but since this question isn't too complicated there should be no need to do so unless you forget how to solve it algebraically*

Step-by-step explanation:
Sheet metal costs $1.88 per square foot. About how much
will Nick spend to cover the outside of the shed, not
including the bottom?
Answer:
Final Cost: $364.72
Step-by-step explanation:
We can see a picture of the shed attached below. To find the total cost we need to first find the surface area of the entire shed. The sides are rectangles, so to find the surface area we need to multiply the length by the width. Since there are two rectangular sides we multiply the result by 2.
A = L * W
A = 10 * 4.7
A = 47 sq ft. * 2sides
Total = 94 sq ft.
Now we calculate the bottom which is also a rectangle
A = L * W
A = 10 * 8
A = 80sq ft.
Now we need to calculate the surface area of the triangular sides and multiply the results by 2 since there are two triangular sides. The formula for the area of a triangle is half times base times height...
A = 0.5 * B * H
A = 0.5 * 8 * 2.5
A = 10 sq ft * 2 sides
Total = 20 sq ft
Finally, we need to add the entire surface area and multiply by the cost per square foot to find the total cost.
94 + 20 + 80 = 194 sq ft
194* 1.88 = $364.72

The hypotenuse of a right triangle is twice the length of one of its legs the length of the other leg is 7 feet find the length of the three sides of a triangle answer exactly or round to two decimal places.
A table is shaped like a regular hexagon. The length of one side is (7x + 4) in. and the length of another side is (8x − 1) in. Find the length of a side.
The length of a side of the table is
Answer:
39 in.
Step-by-step explanation:
As it's a regular hexagon all sides are congruent.
Therefore
7x + 4 = 8x - 1
4 + 1 = 8x - 7x
x = 5.
So the required length is 7(5) + 4 = 39 in.

Answer:
12, 6, 4, 3, 12/7
Step-by-step explanation:
so for each column, you would substitute the number for a in the equation. for example, substituting 2 for a will make the equation 2/2 + b = 12. we now need to isolate b. 2/2(2/2 + b) = 12(2/2) makes the new equation b = 24/2, or b = 12.
Answer:
11,10,9,8,5
Step-by-step explanation:
look at the table.
they are giving you what a equals.
for example: in the table, it says a is 2. SO you put that into the equation you are given.
[tex]\frac{a}{2}[/tex] + b = 12 substitute "a" which we know is 2 into the equation
[tex]\frac{2}{2}[/tex] + b = 12 NOW you solve for b
first, divide 2 by 2 which equals 1
THEN subtract 1 by 12 giving you 11. The equation should look like this
b = 11
11 can then go under 2 on the table.
Do this for the rest of the answers.

Evaluate the function for an input value of 3. f(x)= −4x 2 −3x−5
Answer:
- 50
Step-by-step explanation:
x = 3
f ( x ) = - 4x^2 - 3x - 5
f ( 3 )
= - 4 ( 3 )^2 - 3 ( 3 ) - 5
= - 4 ( 9 ) - 3 ( 3 ) - 5

Find the equation parallel to y = -x - 5 and passing through (-3, -3)
Answer:
y = -x - 6
Step-by-step explanation:
If it's parallel, then it means that the slope will remain the same. The slope is
-1.
To find the y-intercept, you need to plug the coordinates into the equation,
y = -1x + b
-3 = -1(-3) + b
-3 = 3 +b
-6 = b
The equation is y = -x - 6

Answer:
a = 4, x = 1
Step-by-step explanation:
The opposite sides of a parallelogram are congruent , then
WX = YZ , that is
a² + 5a = 5a + 16 ( subtract 5a from both sides )
a² = 16 ( take the square root of both sides )
a = ± [tex]\sqrt{16}[/tex] = ± 4
Since a > 0 , then a = 4
Also
XY = WZ , that is
x² + 6x = 4x + 3 ( subtract 4x + 3 from both sides )
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
Since x > 0 , then x = 1

PLEASE HELP THIS HAS A TIMER The following two-way table shows the distribution of daily traffic and weather issues in a certain large city.
A 4-column table with 3 rows. Column 1 has entries bad weather, good weather, total. Column 2 is labeled heavy traffic with entries 25, 55, 80. Column 3 is labeled Light traffic with entries 5, 15, 20. Column 4 is labeled Total with entries 30, 75, 100. The columns are titled daily traffic and the rows are titled weather conditions.
Suppose a day from this city is selected at random. Let event A = heavy traffic and event B = bad weather. Are events A and B independent?
No, P(A) = P(B|A).
No, P(A) ≠ P(A|B).
Yes, P(A) = P(A|B).
Yes, P(A) ≠ P(B|A).
Answer:
I believe the answer is (B).
Both are not independent, and the probability of A is 30/100.
While the probability for A|B is like 30/100(80/100) which does not equal 30/100.
I've been trying to figure out how to do it and stuff, and this seems the most reasonable answer. I'm taking it now. Goodluck

The two events are not independent as the traffic is affected by the weather conditions.
What is independent probability?Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event. The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B (i.e., P(A and B).
Let event A = heavy traffic and event B = bad weather.
P(A)= 25/30 and P(B)=25/30
Two events are said to be independent only when the change in one event affect the other event.
Here the two given events are not independent.
Band weathers such as heavy rainfall, snowfall etc. leads to failure of traffic management system and thereby causes heavy traffic. This is easily seen in all major urban cities.
Hence, the two events are not independent as the traffic is affected by the weather conditions.

Triangle DAN is graphed on the set of axes below.
The vertices of ADAN have coordinates D(-6,-1),
A(6,3), and N(-3,10).
The area of the triangle DAN is 60 square units if the vertices of ΔDAN have coordinates D(-6,-1), A(6,3), and N(-3,10) option first is correct.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have triangle DAN which is graphed on the set of axes.
The vertices of ΔADN have coordinates:
D(-6, -1), A(6, 3), and N(-3, 10)
We can find the area of the triangle using the coordinates of the triangle such as:
[tex]\rm Area \ of \ the \ triangle = \frac{1}{2} [x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)][/tex]
Let's denote the coordinates N(-3, 10), D(-6, -1), andA(6, 3), and with
[tex]\rm (x_1, y_1), (x_2, y_2), \ and \ (x_3,y_3)[/tex] respectively.
Put these points in the above expression, we get:
[tex]\rm Area \ of \ the \ triangle = \frac{1}{2} [-3(-1-3)-6(3-10)+6(10-(-1))][/tex]
[tex]\rm Area \ of \ the \ triangle = \frac{1}{2} [-3(-4)-6(-7)+6(11)][/tex]
[tex]\rm Area \ of \ the \ triangle = \frac{1}{2} [12+42+66][/tex]
[tex]\rm Area \ of \ the \ triangle = \frac{1}{2} [120][/tex]
Area of the triangle = 60square units
Thus, the area of the triangle DAN is 60 square units if the vertices of ΔDAN have coordinates D(-6,-1), A(6,3), and N(-3,10) option first is correct.

The final balance will come from interest earned will be $1,600.
What is simple interest?Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific amount of time. The principal amount in simple interest is constant.
To find out how much of the final balance will come from the interest earned, you have to determine the total value of the deposits made and subtract this from the balance the account will have after 5 years.
The amount deposited each month: $175
Months: 12 x 5= 60
Total amount deposited: $175*60= $10,500
Interests: $12,100-$10,500= $1,600
According to this, the amount of the final balance that will come from the interest earned is $1,600.
