If you want to go on a field trip to the Bronx Zoo with your science class in 3 months and the trip is $36.00, how much money do you have to save per month?

Answer:

A

Step-by-step explanation:

The system of equations listed in answer A fits both of the criteria.

as x represents the number of 55-inch televisions and y fits the criteria of the number of 65-inch television, we can use the knowledge we have from the question that we can combine these two variables to get a total number of tv's.

As said in the question: "The first week they sold 44 TVs total" meaning that the combined total amount of TV's sold was 44, meaning x + y (which are just variables, not "known" amounts equates to 44.

x + y = 44

The second equation in the system represents the profits. Using the same knowledge from before, we don't know how many how many tv's of each were sold but we can use these variables to present that each 55-inch tv is worth $349 and each 65-inch tv is worth $469.

349x+469y = 17,516 represents this perfectly, thus making A our answer

You have the square QRST, furthermore, you have that sides QS and QU are given by the following algebraic expressions:

QS = 16t - 14

QU = 6t + 11

Due to QRST is a square, the length of all sides are equal.

You can notice by the symmetry of the figure that QS = 2QU

Equal the expressions for QS and 2QU and solvde for t:

16t - 14 = 2(6t + 11) apply distribution property

16t - 14 = 12t + 22 add 14 both sides

16t = 12t + 22 + 14 subtract 12t both sides

16t - 12t = 22 + 14 simplfy like terms

4t = 36 divide by 4 both sides

t = 36/4 simplify the fraction

t = 9

Hence, the value of t is t = 9

The given equation is

To solve for x, the logarithm to indices relationship will be applied

That is

Hence

This is simplified to get

Therefore, the value of x = 4

The value of ∠L is 2.909° as the definition of angle is "An angle is created by joining two line segments at one point, or we can say that an angle is the combination of two line segments at a common endpoint".

An angle is created by joining two line segments at one point, or we can say that an angle is the combination of two line segments at a common endpoint. When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the word "angle" originates. Based on measurement, there are different kinds of angles in geometry. The names of fundamental angles include acute, obtuse, right, straight, reflex, and full rotation. A geometrical shape called an angle is created by joining two rays at their termini. In most cases, an angle is expressed in degrees.

Here,

Side k = 130

Side l = 710

Side m = 833.99204

Angle ∠L = 2.909°

Angle ∠M = 16.091°

Angle ∠K = 161°

Angle L=cos⁻¹((m²+ k² - l²)/2mk)

=cos⁻¹((834²+130²-710²)/2*834*130)

= 2.909°

Since the definition of an angle is "An angle is created by joining two line segments at one point, or we can say that an angle is the combination of two line segments at a common endpoint," the value of ∠L is 2.909°.

Percentage:

Use the percentage formula to express a number or percentage in terms of 100. % simply indicates one out of one hundred. An expression for a number between 0 and 1 can be made using the percentage formula. It is a number that is represented as a fraction of 100. The sign % is used to denote it and it is mostly used to compare and calculate ratios. The formula for percentage increases is the ratio of the increased value to the original value multiplied by 100. It is described in percentage form. If anything is valued more highly, both its value and proportion will rise.

a) is the graph of inverse sine function.

The inverse of the sine function, also known as the arcsine function, returns the angle's value when the sine function's opposite side and hypotenuse ratio are equal. It produces the angle's value.

When the opposing side and hypotenuse of a right triangle are known, the angles can be determined using the inverse sine function. That is, angle = sin-1. The inverse sine function, which is represented as sin-1 or arcsine, is one of the inverse trigonometric functions that calculates the inverse of the sine function. Each restricted domain inverse of a trigonometric function, such as cosine, tangent, cosecant, or cotangent, exists. The trigonometric ratios from the right-angle triangle are utilized to compute the angles using the inverse function formulas.

  $14.17 per hour

Step-by-step explanation:

You want Valerie's average pay to the nearest cent if she works 38 hours per week, for 52 weeks out of the year, receiving annual pay of $28,000.

In a year, Valerie works ...

  (38 hours/week) × (52 weeks/year) = 1976 hours/year

She is paid $28,000 for that number of hours, so her hourly pay is ...

  $28,000/(1976 hours) ≈ $14.17/hour

Valerie's average pay is about $14.17 per hour.

The linear inequality y</5/2 x - 7 does not have any common solution set with the given inequality.

The solution sets of the linear inequality  are drawn in the graph attached below,

From the graph it is seen that the yellow part represents the inequality y≥-5/2 x - 3

And the green section of the graph represents the other inequality

y<-5/2 x - 7

As we can see in the graph that the two areas are separate. So there are no common points.

Again if we consider the two inequalities as two lines  y= -5/2 x - 3

and y = -5/2 x - 7 . we can see that they both have the same slopes of  -5/2 so they are parallel lines. so they will never intersect.
