6. How many 4-inch erasing shields can be cut from a strip of sheet metal 128 inches long? (No allowance is made for waste.)​

Answer:

you end up with 75 divided by 3.

Step-by-step explanation:

75 divided by 3 - 8 + 8

add 60 and 15

3 - 2(4) + 2^3

multiply -2 by 4

3 - 8 + 2^3

multiply 2 by itself 3 times

3 - 8 + 8 (which gives you 3 again)

and you get 75 divided by 3

Manny must save for at least 50 months to have enough money to buy the car. this can be solved by setting up an inequality expression for the condition.

Let's set up an inequality to represent Manny's saving situation.

Manny saves $300.00 per month, so the total amount he will save in m months is 300m. The cost of the used car is $15,000.

To buy the car, Manny needs to save enough money, which can be represented by the inequality: 300m ≥ 15000

This inequality states that the total amount Manny saves, 300m, must be greater than or equal to $15,000, the cost of the car. To solve this inequality for m, we can divide both sides of the inequality by 300: m ≥ 15000/300

Simplifying this expression, we get: m ≥ 50

Therefore, Manny must save for at least 50 months to have enough money to buy the car.

Given:

Two triangles are given in the figure.

To find:

The m∠K and m∠J.

Solution:

In triangle FHK and IGJ,

\(m\angle  F=m\angle I\)          [Given]

\(m\angle  H=m\angle G\)          [Given]

Two corresponding angles are equal. So,

\(\Delta FHK\sim \Delta IGJ\)                   [By AA similarity theorem]

All corresponding angles of similar figures are same.

\(m\angle  K=m\angle J\)             ...(i)

\(4y^2=6y^2-40\)

\(4y^2-6y^2=-40\)

\(-2y^2=-40\)

Divide both sides by -2.

\(y^2=20\)         ...(ii)

Taking square root on both sides.

\(y=\pm \sqrt{20}\)

Now,

\(m\angle K=(4y^2)^\circ\)

\(m\angle K=[4(20)]^\circ\)           [Using (ii)]

\(m\angle K=80^\circ\)

\(m\angle K=m\angle J=80^\circ\)        [Using (i)]

Therefore, the m∠K is 80° and m∠J is 80°.

By solving a simultaneous linear equation, it can be calculated that-

Cost of a single lime is $0.35

What is simultaneous linear equation?

At first it is important to know about linear equation

Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.

A one degree equation is known as linear equation.

Two or more linear equations, which can be solved together to obtain common solution are known as simultaneous linear equation.

Here a simultaneous linear equation needs to be solved

Let the cost of one lime be $x and the cost of one avocado be $y

Carlos buys 3 limes and 5 avocados for a total of $7.40

3x  + 5y = 7.40 .... (1)

Amelia buys 8 limes and 2 avocados for a total of $5.34

8x  + 2y = 5.34

4x + y = 2.67 .... (2)

Multiplying equation (2) by 5

20x + 5y = 13.35 .... (3)

Subtracting (1) from (3)

17x = 5.95

x = \(\frac{5.95}{17}\)

x = $0.35

the unit rate of the crackers will be $0.233.

What is Rate?

A rate in arithmetic is a ratio that contrasts two separate values with various unit systems. For instance, if John types 50 words per minute, that means he types 50 words per minute. We are dealing with a rate because the word "per" is there. The symbol "/" can be used in place of the word "per" in issues.

When two or more similar amounts or numbers are being compared using the same units, a ratio is utilized. When referring to the ratio of one quantity "to" the second quantity in spoken language, it is frequently written with a colon.

A certain brand of crackers costs $2. 89 for 12. 4 ounces.

So per 1 ounce it will cost = 2.89/12.4 = 0.233

Hence the unit rate of the crackers will be $0.233.

The dot product of vectors A and B is not zero, so we can conclude that these vectors are not orthogonal. The dot product of vectors C and D is zero, so we can conclude that these vectors are orthogonal.

We have to find if the vectors A and B are orthogonal or not. For this, we will calculate the dot product of both vectors. If the dot product is zero, then the vectors are orthogonal and if not, then they are not orthogonal.  

So, the dot product of vectors A and B can be calculated as follows:

A . B = (2 * 4) + (3 * (-5))

= 8 - 15

= -7

The dot product of vectors A and B is not zero, so we can conclude that these vectors are not orthogonal. Similarly, we can check the orthogonality of vectors C and D as follows:

C . D = (5 * 2) + (2 * (-5))

= 10 - 10

= 0

The dot product of vectors C and D is zero, so we can conclude that these vectors are orthogonal.

Two vectors are called orthogonal if their dot product is zero. In other words, two vectors are said to be orthogonal if the angle between them is 90 degrees.

The dot product of two vectors can be calculated as the product of their corresponding components, added together.

To check the orthogonality of vectors A and B, we will calculate their dot product as follows:

We checked whether the given vectors are orthogonal or not by calculating their dot product. If the dot product is zero, then the vectors are orthogonal, otherwise, they are not orthogonal. We found that vectors A and B are not orthogonal, while vectors C and D are orthogonal.

The correct statements regarding the angle measures on the diagram are given as follows:

A. m < 4 is greater than m < 1.

C. m < 4 is greater than m < 2.

The exterior angle theorem states that each exterior angle is supplementary with it's respective interior angle, which means that the sum of their measures is of 180º.

From the image given at the end of the answer, we have that the angle 4 is the exterior angle relative to the acute interior angle 3, hence it is an obtuse angle.

As the other angles are acute, we have that angle 4 has a greater measure than all of them.

The equilibrium price is $0 and the equilibrium quantity is 5 units.

To find the equilibrium price and quantity, we need to set the quantity demanded equal to the quantity supplied and solve for the equilibrium values.

Setting Q_d = Q_s, we can equate the equations for demand and supply:

-2Q - 2Q_d = -5 + 3Q_s

Since we know that Q_d = Q_s, we can substitute Q_s for Q_d:

-2Q - 2Q_s = -5 + 3Q_s

Now, let's solve for Q_s:

-2Q - 2Q_s = -5 + 3Q_s

Combine like terms:

-2Q - 2Q_s = 3Q_s - 5

Add 2Q_s to both sides:

-2Q = 5Q_s - 5

Add 2Q to both sides:

5Q_s - 2Q = 5

Factor out Q_s:

Q_s(5 - 2) = 5

Q_s(3) = 5

Q_s = 5/3

Now that we have the value for Q_s, we can substitute it back into either the demand or supply equation to find the equilibrium price. Let's use the supply equation:

P = -5 + 3Q_s

P = -5 + 3(5/3)

P = -5 + 5

P = 0

Therefore, the equilibrium price is $0 and the equilibrium quantity is 5 units.

(3.) 2x^3-4x^2-x + (14/(x+6))

Step-by-step explanation:

The expression for the division of polynomials is obtained as  (2x³- 4x²- x) + 14/(x + 6).

The remainder theorem states that that when a polynomial p(x) is divided by another polynomial x + a, then the remainder obtained is given as the value of the polynomial at x = -a which is written as p(-a).

The given problem can be solved by remainder theorem as follows,

Suppose p(x) = 2x⁴ + 8x³- 25x²- 6x + 14.

Now, when p(x) is divided by x + 6, the remainder is given as,

p(-6) = 2 × -6⁴ + 8 × -6³ - 25 × -6² - 6 × -6 + 14

⇒ p(-6) = 14

Thus, by division lemma the following equation can be written as,

2x⁴ + 8x³- 25x²- 6x + 14 = (x + 6)(2x³- 4x²- x) + 14

⇒ (2x⁴ + 8x³- 25x²- 6x + 14) ÷ (x + 6) = (2x³- 4x²- x) + 14/(x + 6)

Hence, the equivalent expression is given as (2x³- 4x²- x) + 14/(x + 6).

Answer:

The answer is C

Step-by-step explanation:

There are 20 different combinations of committees that can be formed since no person can serve on more than one committee.

In order to form committees of 4, 3, and 2 people, we must first determine how many combinations are possible. There are 9 people in total, so the first committee must consist of 4 people. That leaves 5 people. The second committee must consist of 3 people, leaving 2 people for the final committee. To calculate the total number of combinations, we must multiply the number of choices for each committee. For the first committee, there are 9C4 combinations, for the second committee there are 5C3 combinations, and for the third committee there are 2C2 combinations. Multiplying these together, we obtain 9C4 x 5C3 x 2C2 = 20 combinations. Therefore, there are 20 different combinations of committees that can be formed since no person can serve on more than one committee.
