Equations based on given, 48 coins, total of $6 = 600c:

x + y = 4825x + 5y = 600

Substitute y in the second equation, y = 48 - x

25x + 5(48 - x) = 60025x + 240 - 5x = 60020x = 360x = 18

Then value of y is:

y = 48 - 18 = 30

2) Similarly to problem 1.

x + y = 2025x + 5y = 260

Substitution: y= 20 - x

25x + 5(20 - x) = 26025x + 100 - 5x = 26020x = 160x = 8

Then finding y:

y = 20 - 8 = 12

Slope intercept form - y = m(x) + b. m represents slope, b represents the y-intercept. You should be able to plug in any value for y and x into the equation, and it should result in a true statement.

The y-intercept is easy to find. It is the point where X is equal to zero and the graph line crosses through the y axis. In this case, y intersects at -2. Since we insert the y intercept at b, we can go ahead and plug it in there.

y = m(x) + b > y = m(x) - 2

Since there is only one option with the y intercept equalling -2, you can go ahead and pick D) y = -x - 2 as your answer, since no other options have the correct y-intercept.

In the given figure, ABCD is a trapezium in which AD || BC,
ABC = 90°, AD = 16 cm, AC = 41 cm and BC = 40 cm. Find the
area of the trapezium,

Answers

Answer:

252 cm²

Step-by-step explanation:

Find AB:

AB² = 41² - 40²

AB² = 81

AB = √81

AB = 9 cm

Area of the trapezium = ½(a + b) × h

Where,

a = 16 cm

b = 40 cm

h = 9 cm

Area = ½(16 + 40) × 9

Area = ½(56)×9

Area = 252 cm²

2. Solve:
у = 3х
x = -2y + 70

Answers

the answer should be (10,30)

Answer: (10,30)

Step-by-step explanation:

y = 3x

x = -2y + 70

Solve by using the substitution method. Substitute the value for x into the first equation and solve for y.

y = 3(-2y + 70) Multiply it out

y = -6y + 210 Add 6y to both sides

+6y +6y

7y = 210

y = 30

Since y is equal to 30, input the value for y into the equation and solve for x.

30 = 3x Divide both sides by 3

x = 10

grams, how long would it be until the mass of the sample reached 270 grams,

270=410(1/2)^t/20

Divide both sides by 410

0.6585365854 = (1/2)^t/20

Log Both sides

Log(0.6585365854) / Log(1/2)

A publishing company conducted a survey asking readers whether they use e-readers. Of the 3,000 readers surveyed, 1,954 said they read books on an e-reader. Use this information to complete the statement. Round your answers to the nearest hundredth.

Answers

Answer: See explanation

Step-by-step explanation:

You didn't say what you would like to calculate but based on tbe information given in the question, I guess that you want to calculate the percentage of readers who use an e-reader. This will be:

Number of readers surveyed = 3,000

Number of readers reading on e-reader = 1,954

Percentage of e-readers would then be:

= (1954 / 3000) × 100

= 65.13%
