The difference of the number of grades and the number of degrees of the same angle is 16. Find the number of degrees and grades of the angle.
Answer:
160 grades or 144 degrees================================
Relationship between grade and degree is:
100 grades is same as 90 degrees,or
100G = 90Dor
G = 90D/100G = 0.9DWe have angle x grades for which, the difference of grades and degrees is 16.
We can show this as:
x - 0.9x = 160.1x = 16x = 16/0.1x = 160The number of degrees is:

An insurance agent has a list of 7 prospects and decides to telephone 3 of the prospects today and the other 4 prospects tomorrow. In how many different ways can the agent telephone the prospects?
The number of different ways the agent can telephone the prospects = 1020
In this question, an insurance agent has a list of 7 prospects and decides to telephone 3 of the prospects today and the other 4 prospects tomorrow.
We need to find the number of different ways the agent can telephone the prospects.
We use the formula of permutation.
^n(P_r) = n! / (n - r)!
where n! = n × (n - 1) × (n - 2) × . . . × 1
For this question, n = 7
The number of different ways the agent can telephone the prospects today.
We use r = 3
^7n(P_3)
= 7! / (7 - 3)!
= 210
And the number of different ways the agent can telephone the prospects tomorrow.
We use r = 4
^7n(P_4)
= 7! / (7 - 4)!
= 810
so, the number of different ways the agent can telephone the prospects = 210 + 810
= 1020
Therefore, the number of different ways the agent can telephone the prospects = 1020

Step-by-step explanation:
Rounding to the nearest hundredth means the rounding of any decimal number to its nearest hundredth value. In decimal, hundredth means 1/100 or 0.01. For example, the rounding of 2.167 to its nearest hundredth is 2.17.
You didn't show her answer so I don't know her mistake, but you round to the nearest hundredth by looking at the ten's value, if it's a 5 or greater, add one to the hundredths digit. If its lesser than five, leave the hundredth place.
Ex. Rounding 1,567. Because the tens digit is a 6, you round the 5 up to a 6 and get rid of the tens and one digit. 1,567 rounds to 1,600
Ex. Rounding 1,445. Because the tens digit is a 4, you leave the hundredths digit and get rid of the rest. 1,445 rounds to 1,400.

The Algebra of Functions
Like terms, functions may be combined by addition, subtraction, multiplication or division.
Example 1. Given f ( x ) = 2x + 1 and g ( x ) = x2
+ 2x – 1 find ( f + g ) ( x ) and
( f + g ) ( 2 )
Solution
Step 1. Find ( f + g ) ( x )
Since ( f + g ) ( x ) = f ( x ) + g ( x ) then;
( f + g ) ( x ) = ( 2x + 1 ) + (x2
+ 2x – 1 )
= 2x + 1 + x2
+ 2x – 1
= x
2
+ 4x
Step 2. Find ( f + g ) ( 2 )
To find the solution for ( f + g ) ( 2 ), evaluate the solution above for 2.
Since ( f + g ) ( x ) = x2
+ 4x then;
( f + g ) ( 2 ) = 22
+ 4(2)
= 4 + 8
= 12
Example 2. Given f ( x ) = 2x – 5 and g ( x ) = 1 – x find ( f – g ) ( x ) and ( f – g ) ( 2 ).
Solution
Step 1. Find ( f – g ) ( x ).
( f – g ) ( x ) = f ( x ) – g ( x )
= ( 2x – 5 ) – ( 1 – x )
= 2x – 5 – 1 + x
= 3x – 6
Step 2. Find ( f – g ) ( 2 ).
( f – g ) ( x ) = 3x – 6
( f – g ) ( 2 ) = 3 (2) – 6
= 6 – 6
= 0
Answer: 15-2x
Step-by-step explanation:
h(f(x)) means you have to write equation in f(x) to every x you see in h(x) which is,
h(f(x))=5-2x+4=9-2x
if we need h(f(x-3)) we will take x as x-3 so,

If p-1 is a factor of p4+ p²+ p-k the value of k is
The value of k for the given equation is k = 3.
What is defined as the factor?A factor is a number which divides another number by itself and leaves no remainder.
In the other words, whenever multiplying two whole numbers yields a product, the numbers being multiplied are factors of a product because the product is divisible by them.Factors can be found using two methods: multiplication and division. Furthermore, rules of divisibility might well be applied.The factor of a number is always less than as well as equal to the number; it is never greater than the number.With the exception of 0 and 1, every integer has at least two factors: 1 and the amount itself.For the given equation;
p⁴ + p² + p - k has the factor of p -1.
It means, for p = 1, is the roots of the equation and thus, must satisfy it.
Put p = 1 in the equation and put equal to zero.
p⁴ + p² + p - k = 0
1⁴ + 1² + 1 - k = 0
3 - k = 0
k = 3
Thus, the value of the k is found as 3.

Solve x+5>−3 and −2x−5≤1 and write the solution in interval notation. If there is no solution, type ∅.
Answer:
7/4≤x ≤-1
Step-by-step explanation:
Given the set of inequalities
−5x−3≥2 and 4x−2≥5
We are to write the solution in interval notation. We need to solve them individually first as shown;
For −5x−3≥2
add 3 to both sides
−5x−3+3≥2+3
-5x ≥5
divide both sides by -5 (note that dividing by a negative value will change the sense of the inequality sign)
-5x/-5 ≤5/-5
x ≤ -1
For the inequality 4x−2≥5;
add 2 to both sides
4x−2+2≥5+2
4x≥7
divide both sides by 4;
4x/4 ≥ 7/4
x≥7/4 or 7/4≤x
Combining 7/4≤x and x ≤ -1, the solution in interval notation is expressed as 7/4≤x ≤-1

The values of a and b are 8 and 54 respectively
How to find the values of a and b such that WX is perpendicular to YZ?The given parameters are:
WVY= 4a + 58
XVY = 2b - 18
From the question, we understand that WX is perpendicular to YZ
This means that
WVY= 90
XVY = 90
So, we have
4a + 58 = 90
2b - 18 = 90
Solve for a in 4a + 58 = 90
4a = 90 - 58
Evaluate
4a = 32
Divide by 4
a = 8
Solve for b in 2b - 18 = 90
2b = 90 + 18
Evaluate
2b = 108
Divide by 2
b = 54
Hence, the values of a and b are 8 and 54 respectively
