Use proportional reasoning to find 45% of 200
Answer:
90 i think :)
Step-by-step explanation:
Answer:
90
Step-by-step explanation:
By reasoning, we can say 50% of 200 is 100
We can say 10% of 200 is 20
We divide 20 by 2 to get 5%
20/2
= 10
Subtract 100 by 10
100 - 10
= 90
45% of 200 is 90

find the highest commen factor of 30 and 18
Answer:
6
Step-by-step explanation:
Use prime factorization;
30 = 2 * 3* 5
18 = 2 * 3 * 3
Both of these numbers have ( 2 * 3 ) in common, ( 2 * 3 = 6 ), hence their highest common factor (greatest common factor) is 6.
Answer: the common factor is 6
Step-by-step explanation:
the factor of 30=1x2x3x5
the factor of 18=1x2x3x3
the numbers that are common for both numbers are1, 2 and 3

the fifth term of an arithmetic progression is 40 and the seventh term is 28 more than the 3rd term. Find the first and 10th term.
Answer:
Step-by-step explanation:
t5 = a + (5-1)d
t5 = a + 4d
40 = a + 4d
t3 = a + 2*d
t7 = a + 2d + 28 = a + 6d
Start with the seventh term which has 2 equal answers
a + 2d + 28 = a + 6d Subtract a from both sides
2d + 28 = 6d Subtract 2d from both sides
28 = 4d Divide by 4
28/4 = d
d = 7
==================
t5 = a + 4d = 40
a + 4*7 = 40
a = 40 - 28
a = 12
===================
First term is 12
10th term is
t10 = 12 + (10 - 1)*7
t10 = 12 + 9*7
t10 = 75

The number expression (-5)⁵/(-5)⁻⁶ can be written as -5¹¹ after using the property of the integer exponent.
What is an integer exponent?In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.
We have:
A number expression:
= (-5)⁵/(-5)⁻⁶
As we know from the property of the integer exponent:
[tex]\rm = \dfrac{y^a}{y^b} = y{a-b}[/tex]
y is the base and a, b are the exponent.
As the same base can be written as the sum of the power
In the given number expression there is the same base as -5
Exponent can be subtracted, after subtracting the powers:
= (-5)⁵⁻⁽⁻⁶⁾
= (-5)⁵⁺⁶
= -5¹¹
Thus, the number expression (-5)⁵/(-5)⁻⁶ can be written as -5¹¹ after using the property of the integer exponent.

Bill plans to buy school supplies and the following equation represents what he bought.
5x + 20y = 50 is the equation that shows that he spent $50 and bought 5 binders and 20 pencils. Let
X represent the cost of binders and y represent the cost of pencils
1. How much is each binder if each pencil cost $0.50? Explain how you know.
2. How much is each pencil if the binders cost 8 dollars each? Explain how you know.
Answer:
1. x = 8
2. y = 1/2
Step-by-step explanation:
1. Plug the function
5x + 20(0.50) = 50
= 5x + 10 = 50
Subtract 10 from both side
= 5x = 40
Divide 5 on both sides
= x = 8
2. Plug in the function
5(8) + 20y = 50
= 40 + 20y = 50
Subtract 40 on both sides
= 20y = 10
Divide 20 both sides
= y = 10/20 | 1/2
Answer:
1. 8
Explanation: 5x + 20(.50)=50
5x + 10=50. Now do 50-10 to get 40. So,
5x=40. Now divide 40/5 to get 8.
2. .5
5(8) + 20x=50. Now do 5*8
40 + 20x=50. Now, 50-40 to get
20x=10. And divide 10/20 to get .5

THISS IS SURGENT PLSSS Form a polynomial whose zeros and degree are given.
Zeros: -7, multiplicity 1 3;multiplicity 2; degree 3
Type a polynomial with integer coefficients and a leading coefficient of 1 in the box below.
Answer:
The polynomial is x^3-x^2-33x+63
Step-by-step explanation:
Here, we want to find a polynomial of degree 3 with the given roots
-7 with a multiplicity of 1 and 3 with a multiplicity of 2
if x = -7
x + 7 is a root
if x = 3
x -3 is a root
Since the multiplicity of this is 2, we have x-3 twice
The complete polynomial is;
(x-3)(x-3)(x+7)
= x^2-6x+9(x + 7)
= x(x^2-6x+9) + 7(x^2-6x+9)
= x^3-6x^2 + 9x+7x^2-42x+63
= x^3-x^2-33x+63
