Answer:
Step-by-step explanation:
First, subtract 58% from 100% to get 42%. That means $210 is 42% of this man's income.
Then, convert 42% into a fraction. This would be 21/50. Find the reciprocal of that, which is 50/21.
Now, multiply 50/21 by 210 to get the answer.
(50 * 210)/21
Multiply 50 by 210 to get 10500.
10500/21
(105/21) * 100 is the same as 10500/21.
Divide 105 by 21 to get 5.
5 * 100
Multiply 5 by 100 to get 500.
The man has a $500 income.

Suppose that $8000 is placed in an account that pays 11% interest compounded each year what's the amount after 1 year ? What's the amount in the account after 2 years
Answer:
A = $9,760.00
Step-by-step explanation:
I = A - P = $1,937.50
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3.875%/100 = 0.03875 per year.
Solving our equation:
A = 10000(1 + (0.03875 × 5)) = 11937.5
A = $11,937.50
The total amount accrued, principal plus interest, from simple interest on a principal of $10,000.00 at a rate of 3.875% per year for 5 years is $11,937.50.

Answer:
The atomic number increases as you move from left to right across a period.
Given the table, how can you use a graph to find additional equivalent ratios? x y 2 3 4 6 Plot the ordered pairs (2, 3) and (4, 6). Start at (4, 6). Move right 3 and up 2, and then plot a point. Keep this same rate to get other points. Draw a line through the two given points. Any point below the line represents an equivalent ratio. Plot the ordered pairs (2, 4) and (3, 6). Start at (3, 6). Move right 2 and up 3, and then plot a point. Keep this same rate to get other points. Draw a line through the two given points. Any point on the line represents an equivalent ratio.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
( 1/8 )⁻³ᵃ = ( 512 )³ᵃ be equation (1)
On simplifying the equation , we get
when a = 0
Substitute the value of a = 0 , we get
( 1/8 )⁻³ˣ⁰ = ( 512 )³ˣ⁰
On simplifying the equation , we get
( 1/8 )⁰ = ( 512 )⁰
Any number raised to the power 0 will be 1
So , ( 1/8 )⁰ = ( 512 )⁰ = 1
1 = 1
Therefore , the value of a = 0
Hence , the equation is solved

Kiran says that -2<-5 do you agree with Kiran
Answer:
No it is not possible
Step-by-step explanation:
If two triangles are congruent then they are similar.
Answer:
False.
Step-by-step explanation:
Note the signs:
< is less than
> is greater than
= is equal too
≤ is less than or equal too
≥ is greater than or equal too
~
In this case, Kiran says that -2 is less than -5. However, if you look at a number line (in which the further left it is, the smaller the digit in value, while to the right, the greater the value), -5 is found to the left of -2. Therefore, -2 > -5.

Select one:
a. x < -6
b.X > -6
C.XS-6
d. x > -6
Answer:
b. x > -6
Step-by-step explanation:
> [greater than], and < [less than] inequalities are not filled in because the value is not included, but is only greater or less than.
≥ [greater than or equal to], and ≤ [less than or equal to] inequalities are filled in because the value is included, and it is greater than or less than.
Given that there is an empty circle with an arrow moving in the positive direction from -6, the inequality must be a greater than, and since the value is -6, x > -6.

2. The local Farm Market sells peppers at five for $2.25. Complete the rate table Number of Peppers 1 2 4 5 10 15 20 100 Cost 2.25 What is the constant of proportionality? How do you know?
Answer:
K = $0.45
1____ 2__ 4 __5___10__ 15__ 20__ 100
0.45_0.9_1.8_2.25_4.5_6.75__9___45
Step-by-step explanation:
Given the data:
Number of pepper: 1 2 4 5 10 15 20 100
Cost :
Cost of 5 pepper = 2.25
Using variation :
Cost = number of pepper * k
K = CONSTANT of proportionality
k = cost / number of pepper
k = 2.25 / 5
k = 0.45
Hence,
Cost of pepper = k * number of pepper
Number of pepper:
Cost :
1____ 2__ 4 __5___10__ 15__ 20__ 100
0.45_0.9_1.8_2.25_4.5_6.75__9___45
Choose 3 values for x that would make this inequality true. 24>2 (x+2)
Answer:
9, 2, 0
Step-by-step explanation:
Solving the inequality
24 > 2(x + 2) ← divide both sides by 2
12 > x + 2 ( subtract 2 from both sides )
10 > x
Thus we require values of x that are less than ( but not equal to ) 10
These are 9, 2 and 0
