Answer:

203

Step-by-step explanation:

estimate 28.5 = 29

estimate 7.1 = 7

there for 29 x 7 = 203

The required estimated value of the given expression is 202.

The estimate is defined as a rough view calculation that helps to predict where the product value lies.

Here,
Given expression,
=  (28.5)(7.1)
Multiplying the number under the parenthesis,
Gives,
= 202.35

Now, rounding the numbers, Since the number after the decimal place is close to zero,
= 202.

Thus, the required estimated value of the given expression is 202.

Answer:

x= 4/5a

Step-by-step explanation:

5=5/ax+1

Step 1: Multiply both sides by a.

5a=a+5x

Step 2: Flip the equation.

a+5x=5a

Step 3: Add -a to both sides.

a+5x+−a=5a+−a

5x=4a

Step 4: Divide both sides by 5.

5x/5=4a/5

x= 4/5a

Answer and Step-by-step explanation: Law of deduction is a mathematical logic that states the following:

1) If p happens, then q happens;

2) p is true;

Then, a there is a third statement that is

3) q is also true.

In this question,

If a polynomial is prime, then it cannot be factored.

Statement p is that 5x + 13y is a polynomial and is prime, i.e., p is true.

Statement q is that "it cannot be factored"

Therefore, 5x + 13y cannot be factored.

The law of detachment is used to confirm or refute a claim.

The true statement is: 5x + 13y cannot be factored

The law of detachment states that; for statements p and q

(1) If p then q

(2) p

If the above statements are true, then the following statement is true

(3) q

The statements in the question can be represented as:

(1) If 5x + 3y is a polynomial and is prime then it cannot be factored

(2) It cannot be factored

Using the above representations of p and q, as an illustration; the third statement would be:

(3) 5x + 3y is a polynomial and is prime

Since the third statement is true, then we can conclude that

5x + 13y cannot be factored

[tex]k (3x^3 + 8x - 2) = 12x^3 + 32x - 8[/tex]

Step-by-step explanation:

Set up the composite result function.

k (F (x))

Evaluate k (F (x)) by substituting in the value of into.

[tex]k (3x^3 + 8x - 2) = 4 (3x^3 + 8x - 2)[/tex]

Answer:

The correct option is;

The graph of h(x) passes the horizontal line test

Step-by-step explanation:

In order to determine if a function has an inverse, and also if the inverse of the function is also a function, the function can be tested by drawing an horizontal line the graph of the function and viewing to find the following conditions;

A graph of a function that is intersected at only one point in all places (vertically) by an horizontal line indicates that the function has an inverse that is also a function, while a graph of a function that is intersected at more than one point in some places (vertically) by an horizontal line indicates that the function does not have an inverse that is also a function.

Answer:

Number of nickels: 14

Number of dimes: 31

Total money: $3.80

Step-by-step explanation:

Let number of nickels be x

Number of dimes is 2x+3

Total coins = 45

So add the number of nickels and dimes and it equals 45

x+2x+3=45

3x=45-3=42

x=42/3=14 nickels

Substitute the value of x=14 in 2x+3 to find number of dimes

2(14)+3=28+3=31 dimes

Total money is 14 nickels + 31 dimes

Nickels = 0.05 and dimes is 0.10

14(0.05)+31(0.10)=0.7+3.1=3.8

Answer:

72 sq. inches

Step-by-step explanation:

We are trying to find the area of the shaded part, and so we start with finding the area of the entire half that is marked (the area with measurements). The length is 8 in, as seen on the bottom, and the height is 12 in, as seen on the side. 8 * 12 = 96, so the entire portion from the shaded part to the very right is 96 sq. inches. Now we have to take out the white triangle part to find the area of the shaded part. Area of a triangle = 1/2*base * height, so we multiply 1/2 * 12 * 4, which gets us 24. Now that we know the area of the triangle, we subtract it from the previous area we got, which was the area of the shaded part plus the triangle (96). 96 - 24 = 72, so the area of the shaded portion is 72 sq. inches. Hope this helps!
