Answer:
C. 75 square unitsStep-by-step explanation:
From the question we see that:
b1 = AD = 16 , b2 = BC = 14 , h = 5Use the formula for the area:
A = 1/2(b1 + b2)hA = 1/2(16 +14)(5) = 1/2(30)(5) = 75Correct choice is
C. 75 square unitsAnswer:
75 is correct on edge

Can somebody help me thanks !!!!
Hey there!
The answer is x = 8
The diagonals in a rectangle are always equal, therefore we can set the expressions equal to each other:
8x - 15 = 49
Add 15 to both sides:
8x = 64
Divide 8 on both sides:
x = 8
Have a super awesome day! :)

At what rate does a payment plan for $1,500 accumulate $450 interest after 6 years?
Answer:
At a rate of 5%.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
In this question:
Payment plan for $1500 means that [tex]P = 1500[/tex]
$450 interest after 6 years means that [tex]E = 450, t = 6[/tex]
We have to find the rate I. So
[tex]E = P*I*t[/tex]
[tex]450 = 1500*I*6[/tex]
[tex]I = \frac{450}{1500*6}[/tex]
[tex]I = 0.05[/tex]
At a rate of 5%.
Represent the following Percent as a decimal, 87.5%

Analyzing O! Pioneers
Willa Cather’s 1910 novel, O! Pioneers, follows a Swedish family of farmers in Nebraska.
In this passage, John Bergson is dying and worries about what will become of his wife and
young children. Alexandra is the oldest Bergson child
Alexandra, her father often said to himself, was like her grandfather; which was his
way of saying that she was intelligent. John Bergson’s father had been a shipbuilder, a
man of considerable force and of some fortune. Late in life he married a second time, a
Stockholm woman of questionable character, much younger than he, who goaded him into
every sort of extravagance. On the shipbuilder’s part, this marriage was an infatuation,
the despairing folly of a powerful man who cannot bear to grow old. In a few years his
unprincipled wife warped the probity of a lifetime. He speculated, lost his own fortune
and funds entrusted to him by poor seafaring men, and died disgraced, leaving his
children nothing. But when all was said, he had come up from the sea himself, had built
up a proud little business with no capital but his own skill and foresight, and had proved
himself a man. In his daughter, John Bergson recognized the strength of will, and the
simple direct way of thinking things out, that had characterized his father in his better
days. He would much rather, of course, have seen this likeness in one of his sons, but it
was not a question of choice. As he lay there day after day he had to accept the situation
as it was, and to be thankful that there was one among his children to whom he could
entrust the future of his family and the possibilities of his hard-won land.
Discuss the Meaning
Alexandra shares personal qualities with her grandfather. What are these qualities and
how will they help the Bergson family survive after her father dies? Cite text examples to

In 2004, Pen Hadow and Simon Murray walked 680 miles to
the South Pole. The trip took 58 days.
Answer:
The average number of daily miles traveled by these individuals was 11.72 miles per day.
Step-by-step explanation:
Given that in 2004, Pen Hadow and Simon Murray walked 680 miles to the South Pole, and the trip took 58 days, to determine the average number of miles traveled per day by these individuals the following mathematical calculation must be performed:
680/58 = X
11.72 = X
Thus, the average number of daily miles traveled by these individuals was 11.72 miles per day.

In ΔBCD, the measure of ∠D=90°, the measure of ∠C=83°, and DB= 1.3feet. What is the length of CD to the nearest tenth of a foot.
Answer:
[tex]CD\approx0.2[/tex]
Step-by-step explanation:
By the tangent ratio, [tex]tanC=\frac{DB}{CD}[/tex]. Substituting the given values into this equation gives us:
[tex]tan83[/tex]° [tex]= \frac{1.3}{CD}[/tex]
[tex]CD*tan83[/tex]° [tex]=1.3[/tex] (Multiply both sides of the equation by [tex]CD[/tex])
[tex]CD=\frac{1.3}{tan83\textdegree}[/tex] (Divide both sides of the equation by [tex]tan83\textdegree[/tex])
[tex]CD=0.15962\approx0.2[/tex]

A large cable company reports the following:
80% of its customers subscribe to its cable TV service.
44% of its customers subscribe to its Internet service.
29% of its customers subscribe to its telephone service.
25% of its customers subscribe to both its cable TV and Internet service.
20% of its customers subscribe to both its cable TV and phone service.
23% of its customers subscribe to both its Internet and phone service.
15% of its customers subscribe to all three services.
Consider the chance experiment that consists of selecting one of the cable company customers at random. Calculate the following probabilities.
A) P(cable TV only).
B) P(Internet | cable TV).
C) P(exactly services).
D) P(Internet and cable TV only).
Answer:
[tex]P(Cable\ TV\ only) = 50\%[/tex]
[tex]P(Internet\ |\ cable\ TV) = 31.25\%[/tex]
[tex]P(exactly\ 2\ services) = 23\%[/tex]
[tex]P(Internet\ and\ cable\ TV \only) = 23\%[/tex]
Step-by-step explanation:
Given
[tex]Cable\ TV = 80\%[/tex]
[tex]Internet = 44\%[/tex]
[tex]Telephone = 29\%[/tex]
[tex]Cable\ TV\ and\ Internet = 25\%[/tex]
[tex]Cable\ TV\ and\ Telephone = 20\%[/tex]
[tex]Internet\ and\ Telephone = 23\%[/tex]
[tex]All\ Services = 15\%[/tex]
Solving (a): A) P(cable TV only).
First, we calculate n(cable TV only)
This is calculated as:
[tex]n(cable\ TV\ only) = (Cable\ TV) - (Cable\ TV\ and\ Internet) - (Cable\ TV\ and\ Telephone) + (All\ Services)[/tex]
[tex]n(cable\ TV\ only) = 80\% - 25\% - 20\% + 15\%[/tex]
[tex]n(cable\ TV\ only) = 50\%[/tex]
The probability is:
[tex]P(Cable\ TV\ only) = \frac{n(Cable\ TV\ only)}{100\%}[/tex]
[tex]P(Cable\ TV\ only) = \frac{50\%}{100\%}[/tex]
[tex]P(Cable\ TV\ only) = 50\%[/tex]
Solving (b): P(Internet | cable TV).
This is calculated as:
[tex]P(Internet\ |\ cable\ TV) = \frac{Cable\ TV\ and\ Internet}{Cable\ TV}[/tex]
[tex]P(Internet\ |\ cable\ TV) = \frac{25\%}{80\%}[/tex]
[tex]P(Internet\ |\ cable\ TV) = \frac{25}{80}[/tex]
[tex]P(Internet\ |\ cable\ TV) = 31.25\%[/tex]
Solving (c): P(exactly 2 services).
This is calculated as:
[tex]P(exactly\ 2\ services) = (Cable\ TV\ and\ Internet - All) + (Cable\ TV\ and\ Telephone - All) + (Internet\ and\ Telephone - All)[/tex]
[tex]P(exactly\ 2\ services) = (25\% - 15\%) + (20\% - 15\%) + (23\%-15\%)[/tex]
[tex]P(exactly\ 2\ services) = (10\%) + (5\%) + (8\%)[/tex]
[tex]P(exactly\ 2\ services) = 23\%[/tex]
Solving (d): P(Internet and cable TV only).
This is calculated as:
[tex]P(Internet\ and\ cable\ TV \only) = \frac{(Internet\ and\ cable\ TV \only)}{100\%}[/tex]
[tex]P(Internet\ and\ cable\ TV \only) = \frac{23\%}{100\%}[/tex]
[tex]P(Internet\ and\ cable\ TV \only) = \frac{23\%}{1}[/tex]
[tex]P(Internet\ and\ cable\ TV \only) = 23\%[/tex]
