I need some help to to solve each proportion - I want to be able to explain to my son how to do this properly. The math problem is- 4 over 6 = blank over 21 ?
Answer
The missing value is -14
Step-by-step explanation:
First you make a ratio or proportion: -4/6=x/21
Then you cross multiply
-4x21 which is -84 then 6 times x which is 6x then the equation becomes 6x=-84
from 6x you divide which becomes x=-84/6 which is -14

if Richard worked for 7 dollars and made 9 dollars and hour how much would he make?
Answer:
$63
Step-by-step explanation:
I believe you meant Richard worked for 7 hours and made $9 per hour.
In order to know how much Richard earned for 7 hours, you have to multiply Richard's salary rate with his number of working hours.
7 hours x 9 dollars/hour = $63Therefore, Richard earned $63 for his 7-hour work.
Additional Information
Another example is: if Richard worked for 10 hours, you just have to multiply his salary rate again to his number of working hours.
10 hours x 9 dollars/hour = $90plssss helppppppppp thxxxxxxxxxxx

A5 =
91 and a20 =
1
an=
A25=
Answer:
an = 115 + (n - 1) (-6)
a25 = - 29
Step-by-step explanation:
We use the definition for the nth term of an arithmetic sequence:
an = a1 + (n - 1) d
a5 = 91 = a1 + (5 - 1) d
91 = a1 + 4 d
a20 = 1 = a1 + (20 - 1) d = a1 + 19 d
1 = a1 + 19 d
now we subtract term by term one expression from the other
90 = 4 d - 19 d
90 = - 15 d
divide both sides by -15 to isolate d
d = 90 / (-15) = -6
Now we can calculate what a1 is using for example:
1 = a1 + 19 d
1 = a1 - 114
add 114 to both sides:
115 = a1
Then our general expression for the sequence is:
an = 115 + (n - 1) (-6)
We can now use it to calculate the value of a25:
a25 = 115 + (24) * (-6) = -29

13. Find the arc length with the given information . centralangle = pi/4, radius = 6
14. Which angle has its terminal side in the second quadrant?
Answer:
it is 4th one for 14 it is 2nd one
Step-by-step explanation:
The arc length is 3π/2 and the angle with terminal side in its fourth quadrant is 7π/6.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
We need to find the arc length with the given information . centralangle = π/4, radius = 6
The formula for the arc length of a circle is given by:
Arc length = radius x central angle
In this case, the central angle is pi/4 and the radius is 6. Therefore, the arc length is:
Arc length = 6 x (π/4) = (3/2)π
Option D is correct, the arc length is 3π/2
An angle is said to be in the fourth quadrant if its terminal side lies in the fourth quadrant of the Cartesian plane, which is the quadrant below the x-axis and to the right of the y-axis.
Since the fourth quadrant is to the right of the y-axis, the angle must have a positive x-coordinate
3π/4 has its terminal side in the second quadrant, so it is not the answer.
π/3 has its terminal side in the first quadrant, so it is not the answer.
5π/3 has its terminal side in the third quadrant, so it is not the answer.
7π/6 has its terminal side in the fourth quadrant, so the answer is (d) 7π/6.
Therefore, the angle with terminal side in its fourth quadrant is 7π/6.
