Solve 20x + 5y = 15 for y

Answers

Answer 1

Answer:

Step-by-step explanation:

20x+5y=15

Subtract 20x from both sides.

5y=15−20x

Divide both sides by 5.

__5y_  = _15-20x_____

    5                5

y=  __15-20______

            5

Divide 15−20x by 5.

y=3−4x

A burst of electromagnetic radiation has a frequency of 1 exahertz. One exahertz equals 10^12 megahertz. Each megahertz is equal to 10^6 hertz. What was the frequency of the burst of radiation in hertz? (^ indicates an exponent) *

Answers

Answer:

The frequency of the burst of electromagnetic radiation which equals 1 exahertz = 10¹⁸ hertz.

Step-by-step explanation:

Since the frequency of the burst of electromagnetic radiation is 1 exahertz, and 1 exahertz = 10¹² megahertz. So, the frequency of radiation is 10¹² megahertz. Also 1 megahertz = 10⁶ hertz. So, 10¹² megahertz = 10¹² × 1 megahertz = 10¹² × 10⁶ hertz = 10¹² ⁺ ⁶ hertz = 10¹⁸ hertz.

So the frequency of the burst of electromagnetic radiation which equals 1 exahertz = 10¹⁸ hertz.

If EF = 6 and EG = 23, find the value of FG.

Answers

Answer:

FG=138

Step-by-step explanation:

Since 23 is a prime number, the only factors of it are 1 and 23.

Which means E is either 1 or 23.

Since 23 is not a factor of 6, E=1. Therefore, G= 23. And, F=6.

So, FG=23*6, which means FG=138.

A rectangular parking lot has a length that is 10 yards greater than the width. The area of the parking lot is 600 square yards. Find the length and the width

Answers

Step-by-step explanation:

Let x be the width of the parking lot. Then (x + 10) is the length of the parking lot.

x(x + 10) = 600

x^2 + 10x = 600

x^2 + 10x - 600 = 0

(x+30)(x-20) = 0

x = 20 or x = -30 (rejected as x must be positive)

Hence the length is 30 yards and the width is 20 yards.

A company is looking to hire a lawyer. One law firm states that their legal fees can be determined using the expression 350x + 22,000, where x is the number of hours of legal assistance. A second law firm states that their legal fees can be determined using the expression 410x+16,000. The company president wants to know when the legal fees would cost the same for each law firm. What number of hours of legal assistance makes the equation 350x+22,000 = 410x+16,000 true?

Answers

Answer:

100 hours

Step-by-step explanation:

The number of hours of legal assistance that makes the expressions 350x+22,000 = 410x+16,000 true is 100 hours.

What is an expression?

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. 

We have,

Two expressions that denoted the legal fees for x hours:

350x + 22,000 ____(1)

410x+16,000 _____(2)

Where x = number of hours

The number of hours where both the legal fees are equal:

350x + 22,000 = 410x + 16,000

Subtract 350x on both sides.

22,000 = 410x -350x+ 16,000

22,000 = 60x + 16,000

Subtract 16,000 on both sides.

22,000 - 16,000 = 60x

6,000 = 60x

Divide both sides by 60.

x = 100

Thus,

The number of hours of legal assistance that makes the expressions 350x+22,000 = 410x+16,000 true is 100 hours.

Step-by-step explanation:

i guess that this refers for a system of equations.

y = f(x)

y = g(x)

So to solve this, we usually would write:

2 factory plants are making TV panels. Yesterday, Plant A produced 6000 fewer panels than Plant B did. Two percent of the panels from Plant A and 5% of the panels from Plant B we’re defective. How many panels did Plant B produce, if the two plants together produced 1140 defective panels

Answers

Answer:

Number panels Plant B produce = 18,000

Step-by-step explanation:

Given:

Plant produces defective panels = 1140

Plant B produce = 5%

Plant A produce = 2%

Find:

Number panels Plant B produce

Computation:

Assume

Number panels Plant B produce = x

Number panels Plant A produce = x - 6000

So

5%(x) + 2%(x-6000) = 1140

0.05x + 0.02x - 120 = 1140

0.07x = 1260

x = 18,000

Number panels Plant B produce = 18,000

Answer:

s = 120

r = 33

t = 33

Step-by-step explanation:

You are solving for the variables r & t & s. Note that it is given that the two parallelograms are congruent with each other.

Make sure that they are facing the same way. Note that DC ≅ GH, AD ≅HE, FE ≅ AB

Solve:

DC ≅ GH; 70 = s - 50

Isolate the variable, note the equal sign, what you do to one side, you do to the other. Add 50 to both sides;

70 (+50) = s - 50 (+50)

s = 70 + 50

s = 120

Solve:

AD ≅ HE

2r = 66

Isolate the variable, divide 2 from both sides:

(2r)/2 = (66)/2

r = 66/2

r = 33

Solve:

FE ≅ AB

t + 50 = 83

Isolate the variable, subtract 50 from both sides:

t + 50 (-50) = 83 (-50)

t = 83 - 50

t = 33

What is the image of the point (-8,0) after a rotation of 270° counterclockwise

What is geometric transformation?

It is characterized as the modification of the geometric body's form and coordinates. As a two-dimensional transformation, it is also known as. Rotation, translation, reflection, and gliding translation are only a few of the geometric transformation's conceivable modifications to the geometry.

It is given that the coordinate is  (-8,0) and the point is rotated by 270° counterclockwise about the origin

We have to find the coordinates after a rotation of 270° counterclockwise about the origin.

Plot the points and observe the coordinate in the graph for the given condition.

Thus, following a 270° counterclockwise rotation of the points around the origin, the coordinates of the point (-8, 0) will be (0,-8).

Alessandra is raising turtles and must keep the air temperature in their enclosure at 32. C , with a relative error less than 3%. Write an absolute value inequality for the actual temperature

Answers

The absolute value inequality for the temperature T is:

|T - 32°C| < 0.96°C

How to write the absolute value inequality?

The general way of writing these inequalities is:

|variable - average value| < accepted error.

Here the variable is the temperature so we can use T for it.

The average is 32°C, and the accepted error is less than 3%, so it is:

0.03*32°C = 0.96°

Then the absolute value inequality will be:

|T - 32°C| < 0.96°C

Where it means that the temperature will be at less of 0.96°C of the 32°C.
