an isosceles trapezoid has legs of length 30 cm each, two diagonals of length 40 cm each and the longer base is 50 cm. what is the trapezoid’s area?
768 cm'^2 is the trapezoid’s area.
What is isosceles trapezoid?
Isosceles trapezoids have equal length non-parallel sides, hence the name "isosceles" which means "equal legs". The "legs" are another name for these equal sides.
Let 50 cm = the bottom base
We can find the area of one of the triangles that comprise the area of the trapezoid.....its sides are 30, 40 and 50 cm
Let s be the semi-perimeter of one of the triangle = [ 50 + 40 + 30 ] / 2 = 60 cm
And the area of of this triangle = sqrt [ s ( s - a) (s - b) ( s -c) ] where a,b, c are the sides
So...we have sqrt [ 60 ( 60 - 30) (60 - 40) (60 - 50) ] = sqrt [ 60 * 30 * 20 * 10 ] =
sqrt [ 1800 * 200] = sqrt [ 3600 * 100] = 60 * 10 = 600 cm ^2
Now the base of this triangle = 50 and the height can be found as
follows :
Area = (1/2) 50 * height
600 = 25 * height
height = 24 cm and this is the height of the trapezoid
Now....the top base can be found as 50 - 2 sqrt [ 30^2 - 24^2 ] = 14 cm
So....the area of the trapezoid = (1/2) height ( sum of the bases) = (1/2) (24) ( 50 + 14) = 12 ( 64) = 768 cm'^2

In Exercises 11 and 12, write a rule for the translation of LMN to L'M'N'
The rule for the translation from LMN to L'M'N' is:
(x,y) -> (x + 3, y + 1).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

A professional gamer is preparing for a tournament. in his game he averaged a score of 534 points, every day, for 5 days. then, for the next 3 days he scored a total of 1827 points. finally in another 4 days he averaged a score of 516 points each day. in 12 days how many points in total did this gamer get
In 12 days a professional gamer got 6561 points
We know that average is ratio of the sum of all observations and the number of total observations.
For given question,
A professional gamer averaged a score of 534 points, every day, for 5 days.
⇒ 534 = (total score of 5 days) / 5
⇒ total score of 5 days = 534 × 5
⇒ total score points of 5 days = 2670 points
Then, for the next 3 days he scored a total of 1827 points.
So, the total points of 8 days would be,
total score points of 5 days + total score points of 3 days
⇒ 2670 points + 1827 points = 4497 points.
In another 4 days he averaged a score of 516 points each day.
⇒ 516 = (total score of 4 days) / 4
⇒ total score of 4 days = 516 × 4
⇒ total score points of 4 days = 2064 points
So, the total number of points he did in 12 days:
total score points of 5 days + total score points of 3 days + total score points of 4 days
= 2670 points + 1827 points + 2064 points
= 6561 points
Therefore, in 12 days a professional gamer got 6561 points

A bank loaned out $8200, part of it at a rate of 7.9% per year and the rest of it at a rate of 7.4% per year. The total amount of interest owed to the bank at the end of one year was $614.67.
Find the amount of money that the bank loaned out at 7.9%.
The amount that the bank loaned out at 7.9% is $1,574.00
How do represent the amounts lent at different rates?
On the assumption that x amount was loaned at 7.9% and that the remaining amount, (8,200-x) was loan out at 7.4%, we can determine the interest charged on each loan as the loan multiplied by the interest rate
interest on 7.9% loan=7.9%*x=0.079x
interest on 7.4% loan=7.4%*(8200-x)
interest on 7.4% loan=606.80-0.074x
total interest=0.079x+606.80-0.074x
total interest=0.005x+606.80

Chris made $195 and Alex made $178.50
Week 2:
Michele makes the most with $232
Chris made $192.50 and Alex made $180.83
Week 3:
Alex makes the most with $234.50
Chris made $272.50 and Michelle makes $206
Step-by-step explanation:
For Chris in week 1, multiply 3/100 x 1500 to get what he makes on commission. That equals $45. $150 + $45 = $195
For Michelle in week 1, multiply 15 x 5 = 75. Also multiply 25 x 6.5 = 162.5 to find how much she gets payed by the Pringles. Add it up to get $237.50
For Alex in week 1, multiply 21 x 8.5 = $178.50
For Chris in week 2, multiply 1/40 x 1000 = $25 to get what he makes on commission for the first $1,000. Then multiply 7/200 x 500 = $17.50 to get when he makes on commission for the sales over $1,000. Add it all up and get $192.50
For Michelle in week 2, multiply 10 x 5 = 50 to find how much she gets payed by the Rogers'. Then multiply 28 x 6.5 = 182 to find how much she gets payed by the Pringles. Add it up to get $232
For Alex in week 2, multiply 25 x 7 = 175 to find out how much he earns for 5 hours each day. Then, since Alex worked another 50 minutes, multiply 5/6 x 7 = 5.83. Add it up to get $180.83
For Chris in week 3, multiply 3/200 x 1500 = 42.50 to get what he makes on commission. Then add it with the base salary of 250 to get $272.50
For Michelle in week 3, since the Pringles paid her double, she earned $13 an hour. So, multiply 13 x 12 = 156. Then add it with the $50 she makes from the Rogers' and get $206
For Alex in week 3, multiply 7 by the number of hours he works each day in the week. Get $234.50

Eva left her house at time zero and drove to the store, which is 3 blocks away, at a
speed of 1 block per minute. Then she stopped and went into the store for 3 minutes.
From there, she drove in the same direction at a speed of 1 block every 2 minutes
until she got to the bank, which is 3 blocks away from the store. She stopped at the
bank for 6 minutes. Then she drove home at a speed of 1 block every minute. Make a
graph of showing the number of blocks away from home that Eva is a minutes after
she leaves her house, until she gets back home.
The function f(x), representing the number of blocks Eva is away from her house after x minutes is
[tex]f(x) = \begin{cases} & 0\text{ if } x= 0\\ & x\text{ if } 0 < x\leq 3 \\ & 3\text{ if } 3 < x\leq 6\\ & x/2\text{ if } 6 < x\leq 12\\ & 6\text{ if } 12 < x\leq 18\\ & 24-x\text{ if } 18 < x\leq 24 \\ & 0\text{ if } x > 24 \end{cases}[/tex]
The graph for the same is attached.
In the question, we are asked to form a graph showing the number of blocks, that Eva is away from her home at x minutes, after she leaves her home.
To form the graph, we first try to make a function for x minutes, f(x), showing the number of blocks Eva is away from her home after x minutes.
Since x represents time, it cannot be negative.
At x = 0, f(x) = 0, as she is at her home at 0 minutes.
Then, Eva visits the store, 3 blocks away from her home at a speed of 1 block per minute.
Thus, she moves 1 block every minute up to 3 minutes.
Thus, we get f(x) = x, 0 < x ≤ 3.
After this, she spends 3 minutes at the store, giving f(x) = 3, 3 < x ≤ 6.
Then she moves towards the bank, in the same direction, 3 blocks away at the speed of 1 block every 2 minutes.
Thus, in every minute, she travels 1/2 block.
Thus, the function can be designed as follows:
f(x) = 3 + (1/2)(x - 6), 6 < x ≤ 12,
or, f(x) = x/2, 6 < x ≤ 12.
Now, we are given that she stops at the bank for 6 minutes.
Thus, we get, f(x) = 6, 12 < x ≤ 18.
Now, she drove back home, at the speed of one block every minute.
Thus, we get f(x) = 6 - (x - 18), 18 < x ≤ 24,
or, f(x) = 24 - x, 18 < x ≤ 24.
At the 24th minute, Eva reaches her house back, giving f(x) = 0, x > 24.
Thus, the complete function can be shown as:
[tex]f(x) = \begin{cases} & 0\text{ if } x= 0\\ & x\text{ if } 0 < x\leq 3 \\ & 3\text{ if } 3 < x\leq 6\\ & x/2\text{ if } 6 < x\leq 12\\ & 6\text{ if } 12 < x\leq 18\\ & 24-x\text{ if } 18 < x\leq 24 \\ & 0\text{ if } x > 24 \end{cases}[/tex]

O Zeema gets paid £22,440 per annum. Assuming she gets paid in equal monthly payments, how much does she earn per month?
O Zeema gets paid £1870 per month in equal monthly payments.
The amount paid each month to repay the loan over the course of the loan is known as the monthly payment. When a loan is taken out, not only the principal, or the original amount borrowed, but also the interest that accrues, must be repaid.
Now when the total amount earned in a month is given then the monthly payment is calculated by dividing the total amount by 12 as there are 12 months in a year.
Annual amount earned by O Zeema=£22,440
Therefore monthly amount earned=£22,440 ÷12=£1870

which sequence of rigid transformations will map the preimage ABC onto image A'B'C'?
The sequence of rigid transformations that will map the preimage ΔABC onto image ΔA'B'C' is Option(a) a reflection across the x-axis, a translation 8 units right, and then a reflection across the x-axis.
What is the sequence of rigid transformations?There are three basic rigid transformations: reflections, rotations, and translations.Reflections, as the name implies, mirror the given shape over a particular line. Translations slide or shift a shape from one location to another, whereas rotations spin a shape about a predetermined center point.Co-ordinates of the points of ΔABC are,
A = (-4, 2)
B = (-6, 2)
C = (-2, 6)
point (x,-y) is the reflection of the point (x,y) across the x-axis.
So, new co-ordinates are,
A = (-4, -2)
B = (-6, -2)
C = (-2, -6)
point (x+8,y) is the translation of the point (x,y) by 8 units right.
So, new co-ordinates are,
A = (4, -2)
B = (2, -2)
C = (6, -6)
Then, the reflection of the point (x,y) across the x-axis is the point (x,-y).
So, new co-ordinates are,
A' = (4, 2)
B' = (2, 2)
C' = (6, 6)
These are the coordinates of ΔA'B'C' so the correct answer is Option(a).

The solutions to the equation in the interval are x = π/3, x = 5π/3 and x = π.
What is an equation?A formula for a mathematical equation is one that connects two expressions and expresses their equality using the equals sign (=). In English, an equation is defined as a properly written formula that consists of two expressions connected by an equals sign, however cognates of the word in other languages may have slightly different meanings. For instance, an equation is defined as having one or more variables in French. Finding the variables' values that cause the equality to be true is the first step in solving an equation with variables.
Let's assign a variable to the cosine function, cos(x), and say y = cos (x). Our phrase changes to
4y2 + 2y - 2 = 0
2(2y2 + y - 1) = 0
2y2 + y - 1
= 2y(y+1) - (y + 1)
= (2y - 1)(y + 1)
2(2y-1)(y+1) = 0
y + 1 = 0 = y = -1
The answers cos(x) = 1/2 and cos(x) = -1 result from replacing y with cos(x). Our solutions are x = /3, x = 5/3, and x = on the interval [0, 2], where cos(x) = 1/2 for x = /3 and x = 5/3 and cos(x) = -1.
