find the compound ratio of the following
a) 2/15 : 3/7 and 5/8 : 14/27
please help me
give in step by step
Answer:
1/12 : 2/9Step-by-step explanation:
Compound ratio is the multiplication of the ratios:
2/15 : 3/7 and 5/8 : 14/27Multiply to get:
(2/15*5/8) : (3/7*14/27) = 1/12 : 2/9Given ratios,
2/15 : 3/7 and 5/8 : 14/27
Then to find the compound ratio,
We have to multiply,
→ (2/15 × 5/8) : (3/7 × 14/27)
→ 10/120 : 42/189
Now simplify the ratio,
→ 1/12 : 2/9
Thus, required ratio is 1/12 : 2/9.
which of these is a number that can be expressed as a nonrepeating, nonterminating decimal?
Answer:
an irrational number
Step-by-step explanation:
Answer:
Irrational numbers
Step-by-step explanation:
First, to solve this question, we need to know what irrational numbers are. Irrational numbers are numbers that cannot be expressed as a simple fraction. A nonterminating decimal cannot be expressed as a simple fraction, therefore making it an irrational number.

Use the image to complete the equation below
Given:
A figure in which a transversal line intersect the two parallel lines.
To find:
The missing value for the equation [tex]m\angle \_+m\angle BPD=180^\circ[/tex]
Solution:
In the given figure, the two parallel lines are line ED and line AB, and CD is the transversal line.
Angle BPC and angle BPD lie on a straight line CD. So,
[tex]m\angle BPC+m\angle BPD=180^\circ[/tex] (Supplementary angles)
Angle APD and angle BPD lie on a straight line AB. So,
[tex]m\angle APD+m\angle BPD=180^\circ[/tex] (Supplementary angles)
Therefore, the required complete equations are [tex]m\angle BPC+m\angle BPD=180^\circ[/tex] and [tex]m\angle APD+m\angle BPD=180^\circ[/tex].

answer the question in detail !!!
Answer:
ok so this means 2/5 of the plant have germs and
5-2=3
so 3/5 plants are all good
5 times 20=100
3 times 20=60
so 60% of the plants have germs

a. 17.5
b. 20
c. 22.5
d. 25
Answer:
x = 22.5
Step-by-step explanation:
∠2 and ∠7 are known as alternate exterior angles. This makes them equal to each other.
100 = 4x + 10
90 = 4x
22.5 = x
Identify the maximum value of the function y = -472 - 24x + -36.
Answer:
I assume that this is a quadratic equation, something like:
y = -47*x^2 - 24x + (-36)
we can rewrite it as:
y = -47x^2 - 24x - 36
Ok, this is a quadratic equation and we want to find the maximum value.
First, you can notice that the leading coefficient is negative.
This means that the arms of the graph will open downwards.
Then we can conclude that the vertex of the equation is the "higher" point, thus the maximum value will be at the vertex.
Remember that for a general function
y = a*x^2 + b*x + c
the vertex is at:
x = -b/2a
So, in our case:
y = -47x^2 - 24x - 36
The vertex will be at:
x = -(-24)/(2*-47) = -12/47
So we just need to evaluate the function in this to find the maximum value.
Remember that "evaluating" the function in x = -12/47 means that we need to change al the "x" by the number (-12/47)
y = -47*(-12/47)^2 - 24*(-12/47) - 36
y = -32.94
That is the maximum value of the function, -32.94
can you tell me what these are?

Answer:
[tex]\sin(105) = \frac{\sqrt 2 + \sqrt 6}{4}[/tex]
Step-by-step explanation:
Given
[tex]\sin(105^o)[/tex]
Required
Solve
Using sine rule, we have:
[tex]\sin(A + B) = \sin(A)\cos(B) + \sin(B)\cos(A)[/tex]
This gives:
[tex]\sin(105^o) = \sin(60 + 45)[/tex]
So, we have:
[tex]\sin(60 + 45) = \sin(60)\cos(45) + \sin(45)\cos(60)[/tex]
In radical forms, we have:
[tex]\sin(60 + 45) = \frac{\sqrt 3}{2} * \frac{\sqrt 2}{2} + \frac{\sqrt 2}{2} * \frac{1}{2}[/tex]
[tex]\sin(60 + 45) = \frac{\sqrt 6}{4} + \frac{\sqrt 2}{4}[/tex]
Take LCM
[tex]\sin(60 + 45) = \frac{\sqrt 6 + \sqrt 2}{4}[/tex]
Rewrite as:
[tex]\sin(60 + 45) = \frac{\sqrt 2 + \sqrt 6}{4}[/tex]
Hence:
[tex]\sin(105) = \frac{\sqrt 2 + \sqrt 6}{4}[/tex]

Answer:
x = 28/97
y = 532/
Step-by-step explanation:
x + 5y = 20x + 3y
=> 5y - 3y = 20x - x
=> 2y = 19x
=> y = (19x)/2
x + 5y = 14
=> x + 5((19x)/2) = 14
=> x + (95x)/2 = 14
=> (2x + 95x)/2 = 14
=> 97x = 14(2)
=> 97x = 28
=> x = 28/97
=>y = (19x)/2 = (19(28))/(97(2)) = 532/194

A cell phone company offers a contract that costs $14.99 plus $0.06 per minute. Find the total number of minutes used if the bill for October was $20.21.
Answer:
87 minutes
Step-by-step explanation:
Let the total number of minutes = m
Our equation is given as:
$20.21 = $14.99 + 0.06m
20.21 = 14.99 + 0.06m
Collect like terms
0.06m= 20.21 - 14.99
0.06m = 5.22
m = 5.22/0.06
m = 87
Therefore, the total number rod minutes used is 87 minutes

Statement ∠T and ∠S are complementary ∠S and ∠U are complementary m∠T+m∠S=90 m∠S+m∠U=90 m∠T+m∠S=m∠S+m∠U m∠U=m∠T ∠U≅∠T
Answer:
See Explanation
Step-by-step explanation:
According to the Question,
Given That, ∠T and ∠S are complementary & ∠S and ∠U are complementaryThus, m∠T + m∠S = 90 ------ Equation 1
& m∠S + m∠U = 90 ------- Equation 2
Now, Subtract Equation 2 From Equation 1, we getm∠T - m∠U = 0
Thus, m∠T = m∠U
The measure of angle T is equal to angle U.(∠U≅∠T).

as we know that all the angles in a rectangle are 90° so the,
you will get 90° - 55° = 35°
option D is the right answer.
work out the sizeof angle X
Answer:
x = 13°
Step-by-step explanation:
Since the lines are parallel , then
the lower left vertex of the triangle = 85° ( alternate angles )
the lower right vertex of the triangle = 180° - 98° = 82° ( adjacent angles )
Then
x = 180° - (82 + 85)° = 180° - 167° = 13° ( angle sum of triangle )

Find the nth term for 3,8,13,18
Answer:
5n - 2
Step-by-step explanation:
3 + x = 8
8 - 3 = 5
5 = x
3 (first term) - 5 = -2
5n - 2
Answer:
nth term = 5n - 2
Step-by-step explanation:
The given sequence is 3, 8, 13, 18.
To find the nth term, we have to find the algebraic expression.
Algebraic expression = dn + b'd' means the common difference which can be found by subtracting one term with its previous term. 'b' is the difference between the first term and the com - mon difference.So, d = 8 - 3
d = 5
b = first term - common difference
b = 3 - 5
b = (-2)
Algebraic expression or the nth term =
5n + (-2)
5n - 2.
Thus, the nth term equals to 5n-2!
A line passed through the point (8,5) and has a slope of 2. Write an equation for this line
Since your question doesn't specify what form you need your answer in, I’ll answer in slope intercept form.
Slope intercept form looks like this: y = mx + b.
m represents slope, b represents y intercept. we already have the slope, 2. To find the y intercept, we can plug in the given values for x and y and solve for x.
y = 2x + b
5 = 2(8) + b
5 = 16 + b
- 11 = b
so, the y intercept is - 11. we can plug this into your equation.
y = 2x - 11
There you go! this is your final answer.
Answer:
y= 2x-11 ihope you like it plz mark it brilliant
