How can you use problem-solving strategies in solving personal, professional, and mathematical problems? Explain in 5-7 sentences and I will mark you the brainliest.
Answer:
Step-by-step explanation:
Problem-solving strategies are created as ways of making a problem easier to understand and this leads to it being easier to solve. For example, one strategy is known as compartmentalizing. This involves splitting a problem into various smaller problems. It makes solving these smaller problems easier and less stressful, and once the smaller problems are solved the bigger one is automatically solved as well. Such a strategy can be applied to any problem in any category including math.

If A varies directly as the cube root of B and if A = 3 when B= 64, find the formula con- necting the variables.
Answer:
A = [tex]\frac{3}{4}[/tex] [tex]\sqrt[3]{B}[/tex]
Step-by-step explanation:
Given A varies directly as [tex]\sqrt[3]{B}[/tex] then the equation relating them is
A = k [tex]\sqrt[3]{B}[/tex] ← k is the constant of variation
To find k use the condition A = 3 when B = 64 , then
3 = k [tex]\sqrt[3]{64}[/tex] = 4k ( divide both sides by 4 )
[tex]\frac{3}{4}[/tex] = k
A = [tex]\frac{3}{4}[/tex] [tex]\sqrt[3]{B}[/tex] ← equation of variation
Alice and Bob took a test, which has ten questions. Given that Alice answered six questions correctly and Bob answered eight questions correctly, compute the probability that there exists at least one question on the test which is answered correctly by Alice but not by Bob.
Answer:
0.12
Step-by-step explanation:
Total number of questions in the book = 10
Number of questions answered correctly by Alice = 6
Number of questions answered correctly by Bob = 8
Probability of Alice answering a question correctly = 0.6
Probability of Alice answering a question incorrectly = 1- 0.6 = 0.4
Probability of Bob answering a question correctly = 0.8
Probability of Bob answering a question incorrectly = 1- 0.8 = 0.2
Probability that there exists at least one question on the test which is answered correctly by Alice but not by Bob = 0.6 *0.2 = 0.12

=========================================================
Explanation:
The horizontal pieces are the parallel bases
b1 = 17 and b2 = 9
The height is always perpendicular to the base, so h = 8
The 4 ft portion won't be used in the next section, so we can ignore it.
---------
Plug the values mentioned into the trapezoid area formula below. Simplify.
A = h*(b1+b2)/2
A = 8*(17+9)/2
A = 8*26/2
A = 8*13
A = 104 square feet
We can abbreviate "square feet" into "sq ft" or "ft^2" without quotes.
----------
As another approach, you can split the trapezoid into 2 triangles and a rectangle in between. Then find the area of each small piece, and add up those smaller areas to get the final answer. You should get 104. If you go with this approach, then you will use the 4 ft portion to help find the horizontal length of the triangle on the right.
1. A resident lot has the shape of a parallelogram. Its base measures 20 meters. The distance between the
parallel sides is 8 meters. What is the area of the lot?
Answer:
160 m²
Step-by-step explanation:
Given :
A parallelogram shaped lot :
Base of lot = 20 m
Distance between parallel sides, = height of lot = 8 m
The area of the lot can be obtained using the area formula of a parallelogram :
Area = base * height
Area = 20 m * 8 m
Area = 160 m²

y = = + 7
X-8 -4 0 4
4 8
y| 5 [?] [] [] []
Answer:
x = -4, y = 6.
x = 0, y = 7.
x = 4, y = 8.
x = 8, y = 9.
Step-by-step explanation:
We are given the following rule:
[tex]y = \frac{x}{4} + 7[/tex]
To solve this question, we replace x by the asked values.
When x = -4
[tex]y = \frac{-4}{4} + 7 = -1 + 7 = 6[/tex]
So x = -4, y = 6.
When x = 0
[tex]y = \frac{0}{4} + 7 = 0 + 7 = 7[/tex]
So x = 0, y = 7.
When x = 4
[tex]y = \frac{4}{4} + 7 = 1 + 7 = 8[/tex]
So x = 4, y = 8.
When x = 8
[tex]y = \frac{8}{4} + 7 = 2 + 7 = 9[/tex]
So x = 8, y = 9.
One side of a triangle is 12 feet shorter than the second side. The third side is 2 feet shorter than the second side. The perimeter of a triangle is 55 feet. Find the length of each side.
Answer:
The three sides are 27 feet, 15 feet, 13 feet
Step-by-step explanation:
Let second side of a triangle be = a
Let one side be 12 feet shorter than the second side = (a - 12)
Let the third side be 2 feet shorter than the second side= (a - 12) - 2 =(a - 14)
Perimeter of triangle = Sum of length of all 3 sides
55 = a + (a - 12) + (a - 14)
55 = a + a + a - 12 - 14
55 = 3a - 26
55 + 26 = 3a
81 = 3a
a = 27
Length of one side, a - 12 = 27 - 12 = 15 feet
Length of second side, a = 27 feet
Length of third side, a - 14 = 27 - 14 = 13 feet
The answer is attached. I hope this helps answer your question!

To test this series for convergence
∝
∑ (4^n+7)/7^n
n=1
You could use the limit comparison test, comparing it to the series
∝
∑ r^n
n=1
Where r=???
Completing the test, it shows the series:
r should be 4/7. You're comparing the given series to a geometric series that converges. By the limit comparison test, you have
[tex]\displaystyle\lim_{n\to\infty}\frac{\frac{4^n+7}{7^n}}{\frac{4^n}{7^n}}=\lim_{n\to\infty}\frac{4^n+7}{4^n}=\lim_{n\to\infty}\left(1+\frac7{4^n}\right)=1[/tex]
and since this limit is positive and finite, and the series you're comparing to is convergent, then the first series must also be convergent.

FIND ALL THREE ANGLES
Answer:
Austin = 38
Atlanta = 89
Chicago = 89
Step-by-step explanation:
First, solve for x. All angles together equal 180. Set your formula up as
180 = 2x - 12 + 2x + 3 + 4x - 11
180 = 8x -20
180 + 20 = 8x
200 = 8x
200 / 8 = x
25 = x
Now substitute 25 in place of x
Austin
2x - 12
2*25-12 = 38
Atlanta
4x-11
4*25-11 = 89
Chicago
2x+3
2*25+3 = 53
Add all your angles together to check your work

Step-by-step explanation:
To solve for q, we apply the leg rule theorem or leg geometric mean theorem :
The hypotenus = 18 + 4 = 22
Leg 1 = b
Part1 = 4
According to the leg rule theorem :
Hypotenus / leg 1 = leg 1 / part 1
22 / b = b / 4
Cross multiply :
b * b = 22 * 4
b² = 88
b = √88 = √88 = √4 * √22 = 2√22
From Pythagoras :
a² = b² - 4²
a² = (√88)² - 16
a² = 88 - 16
a² = 72
a = √72 = √36 * √2 = 6√2
