Answer:
b = 48
v = 6
Step-by-step explanation:
Equations:
6v + 8b = 420students
12v + 11b = 600students
----------------------------
Modify for elimination::
12v + 16b = 840
12v + 111b = 600
----------------
Subtract and solve for "b"::
5b = 240
b = 48 (# of students in each bus)
----
Solve for "v"::
6v + 8b = 420
6v + 8*48 = 420
6v = 420-384
6v=36
v = 6 (# of students in each van)
===============
For Check
12(6)+11(48)=600
72+528=600
600=600

Two methods, A and B, are available for teaching a certain industrial skill. The failure rate is 30% for method A and 10% for method B. Method B is more expensive, however, and hence is used only 20% of the time. (Method A is used the other 80% of the time.) A worker is taught the skill by one of the two methods, but he fails to learn it correctly. What is the probability that he was taught by using method A
Answer:
Probability that he was taught by using method A is 14/17
Step-by-step explanation:
Following probabilities are given -
P (F|A) = 0.2
P (F|B) = 0.1
P (A) = 0.7
P (B) = 0.3
Now, P(A|F) = { P (F|A)* P(A)}/{{ P (F|A)* P(A)} + P (F|B)* P(B)}}
P(A|F) = (0.2*0.7)/( (0.2*0.7)+(0.1*0.3)) = 14/17
a = 10, b = 24, c = _____
Answer:
c=26
Step-by-step explanation:
By using pythagoram thoerem
c^2=a^2+b^2
c^2=(10)^2+(24)^2
c^2=100+576
c^2=676
c=sqrt(676)
c=26
c=26

(x, y) = (8, 4)
Step-by-step explanation:
The relations given in the problem statement let you write two equations. One for the number of shots, and one for the number of points. The variables x and y are defined in the problem statement.
x + y = 12 . . . . . total number of shots
x + 2y = 16 . . . . total number of points
__
These equations are easily plotted by considering their x- and y-intercepts. The x-intercepts of the equations are found when y=0, so are 12 and 16, respectively.
The y-intercepts are found when x=0, so are 12 and 8, respectively. The two lines are shown in the attached. The first is blue; the second is red. Their point of intersection at (x, y) = (8, 4) is circled.

In ΔABC, the measure of ∠C=90°, the measure of ∠A=63°, and AB = 35 feet. Find the length of CA to the nearest tenth of a foot.
Answer:
x ≈ 15.9 ft
Step-by-step explanation:
Reference angle = <A = 63°
Hypotenuse = AB = 35
Adjacent = CA = x
Apply trigonometric function CAH:
Cos A = Adj/Hyp
Plug in the values
Cos 63 = x/35
35 × cos 63 = x
15.8896675 = x
x ≈ 15.9 ft

Answer:
Option 4 is correct
x° + 126° = 180° and value of x is 54°
Step-by-step explanation:
Here, In a given Triangle two sides are equal i.e., Isosceles Triangle.
We know that, in a triangle the sum of all angles Is 180°.
If two sides are equal then also two angles are also equal of that sides.
Now,
63° + 63° + x° = 180°
x° + 126° = 180°
Now, To find the value of x
x° + 126° = 180°
x° = 180° - 126°
x = 54°
Thus, The value of x is 54°
FOR VERIFICATION ONLY:-x° + 126° = 180°
54° + 126° = 180°
180° = 180°
Hence, L.H.S = R.H.S

Richard deposits $193.67 every month into his mortgage. At the end of 30 years, he has a balance of $120,182.07. What interest has accrued (been earned) over 30 years?
Answer:
$50,460.87 of interest has been accrued.
Step-by-step explanation:
Richard deposits $193.67 every month into his mortgage.
Each year as 12 months. So after 30 years he will have deposited:
$193.67*12*30 = $69,721.2
At the end of 30 years, he has a balance of $120,182.07. What interest has accrued (been earned) over 30 years?
Interest is total subtracted by deposits. So
120,182.07 - 69,721.2 = $50,460.87
$50,460.87 of interest has been accrued.
Consider the equation x2 = 36. Which of the statements below are true? Select all that apply.
x= v6 is a solution.
x = 6 is a solution.
x = -6 is a solution.
x = -6 is a solution.
There is no solution.
The solution is all real numbers.
+6, -6
Step-by-step explanation:
if the equation is x^2 = 36 then the solving for x we get the square root of 36 which is positive or negative 6

the probability of it raining on a given day is 3/8
what is the probability of its not raining
5/8
Step-by-step explanation:
Probability of raining = 3/8
Total days= 8/8
Then probability of not raining= 8/8 - 3/8
= 5/8
Answer:
5/8.
Step-by-step explanation:
These probabilities add up to 1 so
Probability(Not Raining)
= 1 - 3/8
= 8/8- 3/8
= 5/8.

The double number line shows how far a hummingbird can fly in 1 second.
Answer:
1st box-1
2nd box-3
3rd box-130
Step-by-step explanation:
On the number line, 13 metres is in line with 1 second. So, that means the hummingbird flies 13m/s.
Then to work out the second box, for how much time it takes to travel 39 metres, you would have to do 39÷13=3. This means that in 3 seconds, the hummingbird flies 39 metres in 3 seconds.
To work out how many metres the hummingbird flies in 10 seconds, you would have to do 13×10=130. The reason why you times 13 by 10 is because the hummingbird does 13 metres in 1 second, but we want 10 seconds, so we times it.
Hope this helps :)

Enter a phrase for the expression
Answer:
The quotient of x and 11.
Step-by-step explanation:
Given:
[tex] \frac{x}{11} [/tex]
Required:
Write the expression in words
Solution:
In the expression given, we have the numerator which is the dividend (x), and the denominator which is the divisor (8).
So, we are dividing x into 8 parts.
A quotient is the result you get when you divide the dividend by the divisor.
✅In describing the expression in words, we would use the following phrase:
The quotient of x and 11.
The dividend is mentioned first before the dividend.

angle between the two forces.
The angle between the two forces is ____°
(Round to the nearest integer as needed.)
