Answer:
1/5
Step-by-step explanation:
Since we have given that
Quantity of orange juice = 30 ml
Quantity of apple juice = 20 ml
Quantity of coconut juice = 50 ml
Total quantity of cocktail = 100 ml
So, the ratio of orange juice to apple juice to coconut juice is given by
=30:20:50
= 3:2:5
Total ratio=3+2+5
=10
So, proportion of the cocktail of apple juice is given by
2/10×100
=1/5×100
=20%
Hence, the proportion of the cocktail is 1/5 apple juice
Mr. V went flying a kite. The angle of elevation of the string with the ground is 55
degrees. If the kite is 25 m above ground, how long is the string the kite is on?
Answer:
Length of string = 30.52 m (Approx)
Step-by-step explanation:
Given:
Angle of elevation = 55°
Height of kite = 25 m
Find:
Length of string
Computation:
Sin 55 = Height of kite / Length of string
0.8191 = 25 / Length of string
Length of string = 25 / 0.8191
Length of string = 30.52 m (Approx)
John used digits from 0 to 6 to create a three-digit PIN code. He forgot his PIN code. He remembers that his code contains different ascending digits. What is the maximum number of combinations John has to check to find his PIN code.
Answer:
35 combinations
Step-by-step explanation:
The first digit cannot be 5 or 6 (Since the digits could not be in ascending order if that was the case).
If the first digit is 4, there is 1 possibility:
(4, 5, 6)
If the first digit is 3, there are 3 possibilities:
(3, 4, 5) (3, 4, 6) (3, 5, 6)
If the first digit is 2, there are 6 possibilities:
(2, 3, 4) (2, 3, 5) (2, 3, 6) (2, 4, 5) (2, 4, 6) (2, 5, 6)
If the first digit is 1, there are 10 possibilities :
(1, 2, 3) (1, 2, 4) (1, 2, 5) (1, 2, 6) (1, 3, 4) (1, 3, 5) (1, 3, 6) (1, 4, 5) (1, 4, 6) (1, 5, 6)
If the first digit is 0, there are 15 possibilities:
(0, 1, 2) (0, 1, 3) (0, 1, 4) (0, 1, 5) (0, 1, 6) (0, 2, 3) (0, 2, 4) (0, 2, 5) (0, 2, 6) (0, 3, 4) (0, 3, 5) (0, 3, 6) (0, 4, 5) (0, 4, 6) (0, 5, 6)
Therefore, he would need to try at most 35 combinations.

The diagram shows two straight lines. Work out the value of x
Answer:
136
Step-by-step explanation:
Answer:
136°
Step-by-step explanation:
The angle opposite of x and x are a pair of vertically opposite angles.
Vertically opposite angles are equal in size.
Write the following as an inequality: x is between –12 and 2.5.
The statement - 'x is between –12 and 2.5' can be written in inequality form as -
[tex]-12 < x < 2.5[/tex]
We have a statement : x is between –12 and 2.5.
We have to write it as a mathematical inequality.
Consider the following : if [tex]x[/tex] is between α and β, such that -α < 0 and β > 0, then express this statement as inequality.We can write the inequality as follows -
α < [tex]x[/tex] < β (Since α is less then 0, it will be less then β)
Similarly, we can write the statement - 'x is between –12 and 2.5' in the form of a mathematical inequality as :
- 12 < [tex]x[/tex] < 2.5
Hence, the statement - 'x is between –12 and 2.5' can be written as a mathematical inequality as -
- 12 < [tex]x[/tex] < 2.5

The midpoint of XY is M(0, 4). One endpoint is X(6, –2). Find the coordinate of the other endpoint Y. A.(–6, 10) B.(3, 1) C.(–6, 6) D.(12, 0)
Answer:
The answer is A.
Step-by-step explanation:
Given that the formula for midpoint is :
[tex]m = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )[/tex]
So you have to subtitute the coordinates into the formula :
[tex]let \: m = (0,4) \\ let \: (x1,y1) = (6, - 2)[/tex]
[tex](0,4) = ( \frac{6 + x2}{2} , \frac{ - 2 + y2}{2} )[/tex]
Next, you have to solve it by comparison :
[tex]x⇒ \\ \frac{6 + x}{2} = 0 \\ 6 + x = 0 \\ x = - 6[/tex]
[tex]y⇒ \\ \frac{ - 2 + y}{2} = 4 \\ - 2 + y = 8 \\ y = 10[/tex]

Answer:
x = 37/45
Step-by-step explanation:
Here's how similar triangles work. We set up an equation as SIDE 1A/ SIDE 1B = SIDE 2A/ SIDE 2B
Ok, so these 2 triangles are similar, so we can set up a butterfly equation:
Side 1a would be 8x
Side 1b would be 5x +3
Side 2a would be 10x - 2
Side 2b would be 7x
----------------------------------------------------
Our equation would be
8x/(5x+3) = (10x-2)/7x
We cross multiply to get 8x(10x-2) = 7x(5x+3)
Instead of solving and getting squares, we can x on both sides and we get:
8(10x - 2) = 7(5x+3) ----> we simplify to get
80x - 16 = 35x + 21 ----> it's easy sailing from here.
45x = 37
x = 37/45

17.6
16
4
Answer:
22
Step-by-step explanation:
The answer is 22. You solve the equation 3x+10=7x-6 like so
3x+10=7x-6
-3 = -3
10= 4x-6
+6 = +6
16=4x
x=4
You then plug in the value of x to the equation for LM.
7x-6 becomes 7*4-6 which is 22.

the value of x is: 12. 6. 2. None of the choices are correct.
Answer:
x=6
Step-by-step explanation:
The triangle is an equilateral triangle since all angles are 60 degrees
That means all sides are equal
3x-13 = x-1
Subtract x from each side
3x-13-x = x-1-x
2x-13 =-1
Add 13 to each side
2x= -1+13
2x = 12
Divide by 2
2x/2 =12/2
x = 6
Answer:
B. 6
Step-by-step explanation:
Two angles are 60 degrees, the other is also 60 degrees.
The triangle is an equilateral triangle.
All sides are equal.
3x - 13 = x - 1
3x - x = -1 + 13

Which functions have a vertex with a x-value of 0? Select three options.
f(x) = |x|
f(x) = |x|+ 3
f(x) = |x + 3|
f(x) = |xl - 6
f(x) = |x + 3|-6
Answer:
Hello!
________________________
(A) f(x) = |x|.
(B) f(x) = |x| + 3.
(D) f(x) = |x| - 6.
Would be correct!
Hope this helped you!
The functions that have a vertex with a x-value of 0 are:
f(x) = |x|
f(x) = |x|+ 3
f(x) = |xl - 6
An absolute value function is of the form:
f(x) = a|x - h| + k
where (h, k) represents the vertex
h is the x-coordinate of the vertex
k is the y-coordinate of the vertex
Comparing each of the options with f(x) = a|x - h| + k, the following absolute value functions have a vertex with x-value of 0.
f(x) = |x|
f(x) = |x| + 3
f(x) = |x| - 6

Claim: Most adults would not erase all of their personal information online if they could. A software firm survey of 665 randomly selected adults showed that 49.5% of them would erase all of their personal information online if they could. Make a subjective estimate to decide whether the results are significantly low or significantly high, then state a conclusion about the original claim.
Answer:
State the null and alternate hypothesis which shows a probability value of 0.5 and greater than 0.5 on the one-tailed test to the right respectively. The sample proportion which gives a value of 0.5050. The standard error can then be calculated which gives a value of 0.01925. The Z statistic is then calculated as 0.2598. When compared to a P value of 0.3975, it can be concluded that the null hypothesis is not rejected given the p-value is greater than 0.5.
Therefore, given the not so significant values, there is no sufficient evidence that most adults will not erase their personal information online.
Step-by-step explanation:
With a 0.5 P value as null hypothesis and a an alternative hypothesis greater that 0.5 on a one tailed test. The sample proportion which gives a value of 0.5050. The standard error can then be calculated which gives a value of 0.01925. The Z statistic is then calculated as 0.2598. When compared to a P value of 0.3975, it can be concluded that the null hypothesis is not rejected given the p-value is greater than 0.5.
Therefore, given the not so significant values, there is no sufficient evidence that most adults will not erase their personal information online.
An auditorium has its length, breadth, and height equal to 18m. How much air does it contain? An average adult person requires approximately 0.3 cu.M air per hour. The owner of auditorium organizes a concert there. But he limits the duration of concert 3 hours and allows only 6480 tickets to be sold. Why has the owner taken this decision?
Answer:
The volume of air in the auditorium = 5832 cubic meter
Step-by-step explanation:
Length, breadth, and height of the auditorium = 18m
Therefore, the volume of air in the auditorium
[tex]=18 \times 18 \times 18\\=5832 $ cubic meter[/tex]
An average adult person requires approximately 0.3 cu.M air per hour.
Therefore:
6480 adult person will require: 0.3 X 6480 = 1944 cu.M air per hour.
For three hours:
6480 adult person will require: = 1944 X 3 =5832 cubic meter of air
We notice that the volume of air in the room will be exhausted exactly after 3 hours when 6480 persons attend.
Therefore, the owner has taken this decision to avoid suffocation as an increase in the number of tickets or hours will cause such.
