Answer:
44
Step-by-step explanation:
1. Find out how many coins were foreign
x. 84
------ = ---------
275. 100
2. Subtract 231 (Foreign coins) by 275 (Total coins)
3. The answer is 44
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
The number of foreign coins.
84% of 275 = 231
The number of foreign coins is 231.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Total number of coins = 275
Percentage of foreign coins = 84%
The number of foreign coins.
= 84% of 275
= 84/100 x 275
= 231
Thus,
The number of foreign coins is 231.

Write a polynomial equation of degree 4 that has the following roots: -1 repeated three times and 4.
Answer:
[tex] {x}^{4} - {x}^{3} - {9x}^{2} - {11x}^{2} - 4 [/tex]
Step-by-step explanation:
Since the roots are -1,-1,-1 and 4 we can that as.

A bowling ball is placed on the moon.
Which feature of the bowling ball stays the same?
A. force from gravity
B. weight
C. mass
Answer:
C. mass
Step-by-step explanation:
gravity is different on the moon
and weight is different because of that change in gravity
If the bowling ball is placed on the moon, the feature which will stays same, mass of the ball. So option C is correct
What is Force ?The definition of force is the pushing or pulling of anything. Push and pull are the result of two things interacting with one another. Stretch and crush are two more phrases that can be used to describe force.
Given that,
A bowling ball is placed on the moon
So, when ball is placed on moon, it affects the following factors,
Force from gravity - On the Earth and on the Moon the gravitational force will be different.
Weight - On the Earth and On the Moon the gravitational acceleration will be different so weight will be different on both the planets.
Mass- It is the property of the object and it is independent from the planets, it will be same on every planet.
Hence, the Mass is same on both the planets

B. f(x) = x – 2
C. f(x) = –2x
D. f(x) = 2x
Answer:
D.
Step-by-step explanation:
f(x) increases by 2 as x increases by 1 x value.
We know it isn't A since and x value plue 2 would not equal the y value.
But if you multiply each x-value by 2 you get f(x)
D is the equation for f(x)

Find the value of c so that the polynomial p(x) is divisible by (x-3). p(x) =-x^3+cx^2-4x+3. c=?
Answer:
[tex]\boxed{\textsf {The value of c is $\sf \dfrac{-14}{3}$. }}[/tex]
Step-by-step explanation:
A polynomial is given to us . We need to find the value of c so that it is divisible by (x-3 ) .The given polynomial to us is ,
[tex]\sf \implies p(x)=- x^3+cx^2-4x+3 [/tex]
And the factor is ,
[tex]\sf \implies g(x) = x + 3 [/tex]
Now , according to factor theorem , p(x) will be divisible by g(x) if p(-3) = 0
[tex]\sf \implies p(x)= - x^3+cx^2-4x+3 \\\\\implies\sf p(-3) = 0 \\\\\sf\implies -(-3)^3+c(-3)^2-4(-3)+3 = 0 \\\\\sf\implies 27 + 9c +12+3=0 \\\\\sf\implies 9c +42=0 \\\\\sf\implies 9c = (-42) \\\\\sf\implies c = \dfrac{-42}{9}\\\\\sf\implies \boxed{\pink{\sf c = \dfrac{-14}{3}}}[/tex]
Hence the value of c is (-14)/3 .The value of c will be equal to -14/3.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is p(x) =-x³+cx²-4x+3. The value of c will be calculated as,
p(x) =-x³+cx²-4x+3
p(-3) =-(-3)³+c(-3)²-( 4 x -3) +3
p(-3) = 27 + 9c +12 + 3
27 + 9c +12 + 3 = 0
9c = -42
c = -42/9
c = -14/3
Therefore, the value of c will be equal to -14/3.
