Answer: Sherry has $112

1.26

1) We can calculate that by writing out this algorithm:

We proceed normally as if we had two whole numbers. Multiplying 7 by each number.

Note that since there are two decimal places in the factor 0.18 we count two decimal places from the left to the right in the product.

2) Thus the answer is 1.26

Let's solve the system of equations using elimination:

4x + 5y = 14

-4x -2y = -8

First, we need to get rid of one variable.

Sometimes we multiply them by some factors to have the same number on one variable, but in this case, we can subtract the x variable

4x +5y =14

-4x-2y = -8

----------------------

4x-4x =0, 5y -2y = 3y and 14-8=6

------------------------------

0+3y = 6

Solve the equation for y

Divide by 3 into both sides

3y/3 = 6/3

y = 2

Then, replace this variable on one equation, whichever you want:

4x + 5y = 14

4x +5(2) = 14

4x +10 = 14

and solve the equation for x

4x +10 = 14

Subtract 10 on both sides

4x +10-10 = 14-10

4x = 4

Divide by 4 into both sides

4x/4 = 4/4

x = 1

You can replace both variables to confirm the results:

4x +5y =14

4(1) +5(2) = 14

4 +10 = 14

14 = 14

---------------------------------

-4x -2y = -8

-4(1) -2(2) = -8

-4-4 = -8

-8 = -8

The result is correct, so my ordered pair is (x,y) = (1,2)

The value of the quadratic equation given as x^2 = 25 is 5

Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k

The quadratic equation is given as

x2 = 25

Rewrite the equation properly

So, we have

x^2 = 25

Take the square roots of both sides

x = 5

Hence, the solution of the equation is 5

Since the domain is restricted to one side of the axis of symmetry of the full graph of f(x), an inverse does exist.

Letting [tex]f(x)=y[/tex],

[tex]x=y^2 +y-6\\\\x=\left(y+\frac{1}{2} \right)^2 -\frac{25}{4}\\\\x+\frac{25}{4}=\left(y+\frac{1}{2} \right)^2[/tex]

Since the domain is restricted to the right hand side of the axis of symmetry, and since the range of the inverse is the same as the domain of the original function, we take the positive square root.

[tex]\sqrt{x+\frac{25}{4}}=y+\frac{1}{2}\\\\y=f^{-1}(x)=\sqrt{x+\frac{25}{4}}-\frac{1}{2}[/tex]

The domain of the inverse is the range of the original function, which is [tex]\left[-\frac{25}{4}, \infty \right)[/tex].

The range of the inverse is the domain of the original function, which is [tex]\left[-\frac{1}{2}, \infty)[/tex],

Kali will have to work a minimum of 10 hours and a maximum of 22 hours to earn between 200 and 400. The inequality representing the solution will be 9 ≤ 15.75x ≤ 22.

In the question, it is stated that Kali earns $15.75 and a flat fee 0f 50. She wants to maintain her earnings between 200 and 400. Potential earning will be 'x'. The equation representing the earnings is 200 ≤ 15.75x + 50 ≤ 400. We will have to solve the inequality and find out the value for x.

=> 200 ≤ 15.75x + 50 ≤ 400

Subtracting 50 from the equation,

=> 150 ≤ 15.75x ≤ 350

Dividing the equation by 15.75

=> 9.52 ≤ x ≤  22.22

So, here x lies between 9.52 and 22.22. After rounding off we get range 10 and 22.

Hence, the solution for the inequality is 9.52 ≤ x ≤  22.22

Answer: 3 Vans are needed.

Step-by-step explanation:

There are 30 students so already you need 3 vans, if you only have 2 vans, you will be leaving behind 10 students so regardless you need a 3rd van. with 3 vans you can hold 33 people. 30 students+ 3 drivers=33 people.

The inequality that represents the number of vans for the given case is V ≤ 30/11.

Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.

Unlike a linear equation it can have a range of values inside an interval.

Suppose the number of vans be V.

The number of students for each van is 11.

And, the total number of students is 30.

Now, the inequality for the number of vans can be written as,

11V ≤ 30

⇒ V ≤ 30/11

Hence, the inequality for the number of vans is given as  V ≤ 30/11.

Therefore, number of bundles of tomatoes which was sold as selling price are: 225.5

What is selling price or sale?

In mathematics, the term selling price can be explained with the help of profit which states, as the amount which is on the commodity and in the form of standard price called selling price. For the profit, the amount of the commodity can be designed by the shopkeeper which is bigger amount as per the cost price.

According to the question, the organic producer sells bundle of tomatoes as the selling price of $8 and the bunches of green beans as $5.

Total sales amount is: $464

In this, people bought three times more tomatoes as green bean bunches.

Let us assume tomatoes be 'x' and green beans be 'y'

3x + y = $464

x + y = $13

⇒ 2x = 451

⇒ x = 225.5 dollars

Therefore, number of bundles of tomatoes which was sold as selling price are: 225.5 dollars

Answer:

Step-by-step explanation:

the angles in a triangle add up to 180

2x + 3x + 4x = 180

(combine like terms)

9x = 180

(divide both sides by 9 to find out what x is)

x = 20

so now we know

(2x)° = 40°

(3x)° = 60°

(4x)° = 80°

Step-by-step explanation:

Based on the triangle inequality theorem, the set of side measurements that could be used to form a triangle is: D. 5, 11, 8.

The triangle inequality theorem states that three set of side measurements, a, b, and c would form a triangle if a + b > c, that is, the sum of any of two sides should be greater than the third side.

The set of side of measurements 5, 11, 8 will form a triangle because:

5 + 11 > 8 ⇒ 16 > 8

5 + 8 > 11 ⇒ 13 > 11

8 + 11 > 5 ⇒ 19 > 8

The other set of side of measurements do not conform to this criterion set by the triangle inequality theorem, therefore, the only set of side measurements that will form a triangle is: D. 5, 11, 8.

What is a linear inequality and how is it solved?
Expressions with linear inequalities compare any two values using inequality symbols like "<" and ">." The mathematical expression with unequal sides is known as an inequality in mathematics. Inequality is referred to in mathematics when a relationship results in a non-equal comparison between two expressions or two numbers. Polynomial inequality, rational inequality, and absolute value inequality are the several types of inequalities that exist in mathematics.
First, create an equation for the inequality. The given equation must be solved for one or more values. Represent all of the values that you found on the number line now. On the number line, use open circles to symbolize the excluded values. the interval, then. To determine whether the values satisfy the inequality equation, substitute any random value from the interval into the inequality equation. The solutions of the given inequality equation are intervals that fulfil the inequality equation.

Given, the linear inequalities are t + 1 < -5 and t + 1 > 5
Solving the first inequality, t + 1 < -5 ⇒ t < -5 -1 ⇒ t < -6
Again, solving second inequality, t + 1 > 5 ⇒ t > 5 - 1 ⇒ t > 4
Combining the solution of both the inequalities, we have;
the value of t can take any value in (-∞, -6) U (4, ∞).
Therefore, the required value of t is (-∞, -6) U (4, ∞).
