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

Answers
∛(1/8 - x) = -1/2
Take the 3rd power of both sides and solve:
(∛(1/8 - x))³ = (-1/2)³
1/8 - x = -1/8
2/8 = x
x = 1/4

у = 3х
x = -2y + 70
Answers
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
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%

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.
Write the equation of the line that passes through (-3,9) and is parallel to y = -2x + 5
Answers
Answer:
y = -2x +3
Step-by-step explanation:
Parallel lines always have the same slope
To insert the point, use the slope intercept formula: y =mx+b
insert y (9)
insert x (-3)
insert the slope -2
9 = (-2)(-3) + b
9 = 6+b
subtract 6 from both sides
3 = b

Element X is a radioactive isotope such that every 20 years, its mass
decreases by half. Given that the initial mass of a sample of Element X is 410
grams, how long would it be until the mass of the sample reached 270 grams,
to the nearest tenth of a year?
Answers
Answer:
12.1
Step-by-step explanation:
y=a(1/2)^t/h
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)
.6026645024= t/20
20 x .6026645024 = t
12.05329005 to the nearest tenth is 12.1 = t
