Answers

Answer 1

after subtracting and simplifying the expression ( 2 x⁴ + 5 x³ - 8 ) - ( 9 x ² - 8 x + 8 ), we get the result as 2 x⁴ + 5 x³ - 9 x² + 8 x - 16.

We are given an expression:

( 2 x⁴ + 5 x³ - 8 ) - ( 9 x ² - 8 x + 8 )

We need to subtract the expression and simplify the result.

We get that:

Subtracting the expression, we get that:

2 x⁴ + 5 x³ - 8 - 9 x ² + 8 x - 8

Simplifying the expression, we get that:

= 2 x⁴ + 5 x³ - 9 x² + 8 x - 16

Therefore, after subtracting and simplifying the expression ( 2 x⁴ + 5 x³ - 8 ) - ( 9 x ² - 8 x + 8 ), we get the result as 2 x⁴ + 5 x³ - 9 x² + 8 x - 16.

Question 7A: Keisha has $585.43 in her checking account. She must maintain a balance of $300 to avoid a fee. She wrote a check for $302.05 today. Write an inequality, using x for the variable, that would be used for the least amount of money she needs to deposit to avoid a fee.

Question 7B: Using your inequality from question 7A, solve the inequality to find the least amount of money Keisha can deposit to avoid a fee.

Answers

The least amount of money she needs to deposit to avoid a fee is;  $16.62

How to Solve Inequality Word Problems?

We are given;

Amount Keisha has in her checking account = $585.43

Minimum balance to be maintained = $300

Check written = $302.05

Now, if x represents the variable, that would be used for the least amount of money she needs to deposit to avoid a fee, then the inequality is;  $585.43 - $302.05 + x ≥ $300

$283.38 + x ≥ $300

Subtract 283.38 from both sides to get;

For the false statement we use the symbol ( ~ ).

If in the statement the word ''or'' is present then we use the symbol ''∧'' and for the word ''and'' we use the symbol ''∨''.

Hence,

For the statement;

Both are truth and with the word ''or'', then the symbolic notation,

⇒ p ∧ q

For the statement;

b. Atlanta is the capital of Georgia and there are not 3 feet in a yard.

One statement is truth and second is false , then the symbolic notation,

⇒ p ∨ ~ q

For the statement;

c. Atlanta is not the capital of Georgia, or there are 3 feet in a yard.

First statement is false and second is truth , then the symbolic notation,

⇒ ~ p ∧ q

The formula for relating a man's shoe size S and the length of his foot L in inches is
S3L
26. Find the length of a man's foot if he wears a size 12 shoe.

Answers

Answer:

  12 5/6 inches

Step-by-step explanation:

You want to find the value of L when S=12 1/2, using the formula S = 3L -26.

Foot length

You can substitute for S in the formula before or after you solve for L. Here, we'll solve for L first:

  S +26 = 3L . . . . add 26 to both sides

  (S +26)/3 = L . . . . divide both sides by 3

Substituting 12 1/2 for S, this becomes ...

  L = (12 1/2 +26)/3 = (38 1/2)/3 = (77/2)/3 = 77/6 = 12 5/6

A man's foot is 12 5/6 inches long if he wears a size 12 1/2 shoe.

What is root of Polynomial?

Polynomial roots are the answers to any polynomial for which we need to determine the value of the unknowable variable. Knowing the roots will allow us to evaluate the polynomial's value to zero. A polynomial of degree "n" in variable x is an expression with the following formula: anxn + an-1xn-1 +...... + a1x + a0.

The greatest power of a variable in a polynomial is referred to as the polynomial's degree.

A monomial is a polynomial with a single term. A monomial is referred to as a polynomial of zero degrees if it simply has a constant term.

The price of eight 4.23 ounce juice boxes is $2.39. we should always know that: 1 Gallon = 128 Ounces and 1 juice boxes = 4.23 ounce

So, juice boxes per gallon = 128/4.23 = 30.26

But the worth of 8 juice boxes is $2.39

The value of 1 gallon = (30.26/8) * 2.39 = 9.04

Answer:

163 degrees

Step-by-step explanation:

163 degrees is equal to y

Z = x

The measure of angle y is 163° and the measure of angle x and z is 17 degrees.

Given that:

Two lines are intersected with each other.

It is required to find the measure of angles x, y, and z.

The angles formed on the opposite side of the intersecting line are called vertical angles.

Also, by the Vertical Angles Theorem, the vertical angles formed are always equal.

Here, y is vertical to the given measure of 163°.

So, y = 163°.

Now, x and y are the angles formed along a line.

So, they are linear pair of angles.

Linear pair of angles are supplementary.

So, x + y = 180

x = 180 - 163

  = 17°

Also, x and z are vertical angles.

So, z = 17°

Hence, x = 17°, y = 163°, and z = 17°.

Marc mixes blue and yellow paint to make his favorite shade of green, which he'll use to paint his house. He has 14 cans of blue paint and 20 cans of yellow paint when he starts.

He wants the same green color every time he mixes, so the amounts of blue and yellow must always be proportional to the original mixture.

On day 1, he mixes 4 cans of blue and 6 cans of yellow.
On day 2, he mixes 6 cans of blue and 9 cans of yellow.

Fill in the blanks to find the highest number of cans of each color Marc can mix to make the same shade of green on day 3.




1 On days 1 and 2 how much blue paint did Marc use? How much yellow paint?

2 How many cans of each type of paint does Marc have left for day 3?

3 Day 2's mixture must use the same simplified ratio of blue to yellow as the other two days. What is the greatest number of cans of blue and yellow paint Marc can mix on day 2? Assume he mixes only whole cans of paint.

Answers

By respecting the given ratio:

1) 10 of blue paint and 15 of yellow.

2) 4 of blue paint and 6 of yellow.

3) 2 cans of blue paint and 3 of yellow.

On days 1 and 2 how much blue paint did Marc use? How much yellow paint?

We know that on day 1 he uses:

4 cans of blue paint.6 cans of yellow paint.

On day 2 he uses:

6 cans of blue paint.9 cans of yellow:

Adding that we get:

Cans of blue paint used: 4 + 6 = 10Cans of yellow paint used: 6 + 9 = 15

How many cans has he left on day 3?

He initially has 20 cans of yellow, so he has left:

20 - 15 = 5 cans of yellow.

He initially has 14 cans of blue, so now he has:

14 - 10 = 4

4 cans of blue paint.

3) How many cans should he use?

The original ratio is:

6 yellow to 4 blue.

The quotient gives: 6/4 = 3/2

So if she has 5 cans of yellow paint and 4 cans of blue paint, the maximum amount that he can use that respects that ratio is 3 cans of yellow paint and 2 cans of blue paint.
