Answer:
[tex]Height=\boxed{10\sqrt{2}} [/tex]
[tex] Area =\boxed{165\sqrt{2}} [/tex]
Step-by-step explanation:
By geometric mean theorem:
[tex] AC=\sqrt{25\times 8}[/tex]
[tex] AC=\sqrt{5^2 \times 2^2 \times 2}[/tex]
[tex] AC=5\times 2\sqrt{2}[/tex]
[tex] AC=10\sqrt{2}[/tex]
So,
[tex]Height=\boxed{10\sqrt{2}} [/tex]
[tex] Area = \frac{1}{2} \times base\times height [/tex]
[tex] \therefore Area = \frac{1}{2} \times (25+8)\times 10\sqrt{2} [/tex]
[tex] \therefore Area =33\times 5\sqrt{2} [/tex]
[tex] Area =\boxed{165\sqrt{2}} [/tex]

Answer:
A) 12 pieces
B) the meaning of the quotient is that Tara got 12 pieces of length 2/5 ft from her 4 4/5 ft rope
Step-by-step explanation:
A) (4 4/5)/(2/5) = (24/5)/(2/5) = 24/2 = 12
Tara can cut 12 pieces from the rope.

B) The quotient is the answer to the question. The meaning of it is that Tara can get 12 pieces from the rope, in answer to the question, "how many pieces can Tara cut?"
It doesn't matter whether the numbers are whole numbers, decimals, fractions, or even irrational numbers. The whole is the sum of the parts, so the number of parts is equal to the size of the whole divided by the size of a part.

Comment on the question
This sort of question seems to appear a lot in modern "common core" math materials. They tell you "x means <such and such>", and then they ask you, "What is the meaning of x?" It seems to be a reading comprehension exercise. Of course, the meaning of x is <such and such>, just as the problem statement tells you.

Answers

Answer:
(c) 18.55
Step-by-step explanation:
The law of sines tells you ...
y/sin(106°) = 15/sin(51°)
y = 15×sin(106°)/sin(51°)
y ≈ 18.55
_____
The same kind of proportion can find x:
x = 15×sin(23°)/sin(51°)
x ≈ 7.54
Please note that the question posted here asks for the value of y. The value of x and the complete triangle solution are provided as a courtesy to those who may be asked for other values in this triangle.

Solve 7x- c = k for x
Answers
Answer:
D
Step-by-step explanation:
I know the answer is D because I set the equation to be equal to x.
First, I added c to both sides. The equation looked like: 7x=k+c
Then, I divided 7 on both sides, so x would be by itself. The equation looked like x=k+c/7
In conclusion, the answer is D. x=k+c/7

Answer:
1. 74.6° = m∠C 65.4° = m∠A a = 2.83
2. Triangle does not exist
Step-by-step explanation:
1. Use the law of sines to find m∠C
sin 40/2 = sin C/3
3sin 40/2 = sin C = .96418...
arcsin .96418... = 74.6° = m∠C
m∠A = 180 - 40 - 74.6 = 65.4°
a/sin 65.4 = 2/sin 40
a = 2 sin 65.4/sin 40 = 2.83
2. sin 95/4 = sin C/5
5sin 95/4 = sin C = 1.2452... which is impossible since the cosine of an angle is ≤ 1
A muralist is painting the side wall of a building. The wall is shaped like a rectangle that is 60
feet long and has a diagonal length of 68 feet. If a gallon of paint can cover 800 square feet,
how many gallons will the muralist use?
Answers
Answer:
2.4 gallons
Step-by-step explanation:
to answer this question :
we have to determine the width of the rectangle.
determine the area
determine the gallons needed
Pythagoras theorem would be used to determine the width of the wall
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
60² + b² = 68²
3600 + b² = 4624
b = ²4624 - 3600 = 1024
√b = 32
Area of a rectangle = length x width
32 x 60 = 1920
Gallons needed = 1920 / 800 = 2.4 gallons
Write rational numbers between 0 and 1

Last year Jacob’s total sales were $512,045. This year he increased his sales to $595,679. What is the increase in sales
Answers
Answer:
$83,634
Step-by-step explanation:
The computation of the increase in sales is shown below:
Given that
The total sales is $512,045
And, the increase his sales to $595,679
So based on the above information
The increase in sales is
= $595,679 - $512,045
= $83,634
Hence, the increase in sales is $83,634 that means the sales would be increased by $83,634
