Answer:
25 in ^2
Step-by-step explanation:
First find the area of the circle
A = pi r^2
A = 3.14 ( 4.3)^2
A =58.0586
The take the fraction of the circle that is shaded
A circle is 360 degrees
155/360
155 /360 * the total area = area shaded
31/72 * 58.0586 = 24.99745278 in ^2
Rounding yields 25 in ^2
Answer:
25[tex]in^2[/tex]
Step-by-step explanation:
To find the area we need to use the expression [tex]\frac{x}{360}[/tex] · [tex]\pi r^2[/tex]
When you substitute and solve you should get 25[tex]in^2[/tex]
Which point on the graph of g(x)=(1/5)^x? HELPP
Answer:
(-1,5) and [tex](3, \frac{1}{125})[/tex] are points on the graph
Step-by-step explanation:
Given
[tex]g(x) = \frac{1}{5}^x[/tex]
Required
Determine which point in on the graph
To get which of point A to D is on the graph, we have to plug in their values in the given expression using the format; (x,g(x))
A. (-1,5)
x = -1
Substitute -1 for x in [tex]g(x) = \frac{1}{5}^x[/tex]
[tex]g(x) = \frac{1}{5}^{-1}[/tex]
Convert to index form
[tex]g(x) = 1/(\frac{1}{5})[/tex]
Change / to *
[tex]g(x) = 1*(\frac{5}{1})[/tex]
[tex]g(x) = 5[/tex]
This satisfies (-1,5)
Hence, (-1,5) is on the graph
B. (1,0)
x = 1
Substitute 1 for x
[tex]g(x) = \frac{1}{5}^x[/tex]
[tex]g(x) = \frac{1}{5}^1[/tex]
[tex]g(x) = \frac{1}{5}[/tex]
(1,0) is not on the graph because g(x) is not equal to 0
C. [tex](3, \frac{1}{125})[/tex]
x = 3
Substitute 3 for x
[tex]g(x) = \frac{1}{5}^x[/tex]
[tex]g(x) = \frac{1}{5}^3[/tex]
Apply law of indices
[tex]g(x) = \frac{1}{5} * \frac{1}{5} * \frac{1}{5}[/tex]
[tex]g(x) = \frac{1}{125}[/tex]
This satisfies [tex](3, \frac{1}{125})[/tex]
Hence, [tex](3, \frac{1}{125})[/tex] is on the graph
D. [tex](-2, \frac{1}{25})[/tex]
x = -2
Substitute -2 for x
[tex]g(x) = \frac{1}{5}^x[/tex]
[tex]g(x) = \frac{1}{5}^{-2}[/tex]
Convert to index form
[tex]g(x) = 1/(\frac{1}{5}^2)[/tex]
[tex]g(x) = 1/(\frac{1}{5}*\frac{1}{5})[/tex]
[tex]g(x) = 1/(\frac{1}{25})[/tex]
Change / to *
[tex]g(x) = 1*(\frac{25}{1})[/tex]
[tex]g(x) = 25[/tex]
This does not satisfy [tex](-2, \frac{1}{25})[/tex]
Hence, [tex](-2, \frac{1}{25})[/tex] is not on the graph

Five test scores have a mean (average score) of 90, a median (middle score) of 91 and a mode (most frequent score) of 94. Find the sum of the two lowest test scores.
Answer:
171 points.
Step-by-step explanation:
If five test scores have a mean of 90, all the scores added together will be 5 * 90 = 450.
The middle score is 91, so the other four scores added together will be 450 - 91 = 359.
The mode is higher than the median, so we can assume that the highest two numbers are the same: 94. 94 * 2 = 188. 359 - 188 = 171.
That means that the sum of the two lowest test scores is 171 points.
Hope this helps!
Answer:
The sum of the two lowest test scores is 171.
Step-by-step explanation:
We see that there are 5 test scores, so the median ( middle score ) was not taken to be the average of the two middle scores. It is an element present in the set of five test scores. The mode of course has to be present in the set, but multiple times. If we can figure out how many times this mode is present in the set, it would help us.
As 91 is the middle value, there has to be two above 91. Therefore, as 94 appears the most frequent, is must appear twice.
Now another key thing we need here is the sum of all 5 numbers. Given a mean of 90, 90 [tex]*[/tex] 5 = the sum of all 5 numbers = 450. Therefore, the sum of the two lowest test scores should be = 450 - 94 - 94 - 91 = 171 - which is our solution.
so A =3x2+4x+1,B=5x2−3x+8,C=4x2−7x−3, find the value of B + C –A.
Answer:
6x² - 14x - 4Step-by-step explanation:
A =3x² + 4x + 1
B = 5x² - 3x + 8
C = 4x² - 7x - 3
B + C –A is
5x² - 3x + 8 + 4x² - 7x - 3 - ( 3x² + 4x + 1)
Expand and simplify
We have
5x² - 3x + 8 + 4x² - 7x - 3 - 3x² - 4x -1
Group like terms
5x² + 4x² - 3x² - 3x - 7x - 4x + 8 - 3 - 1
We have the final answer as
6x² - 14x - 4Hope this helps you
Find the area of the shape shown below.
Answer:
6[tex]cm^{2}[/tex] (assuming the units is in centimetres)
Step-by-step explanation:
Hi, hope this helps!
Method 1:
Calculate this shape as a trapezium. This is a trapezium because it has one pair of parallel sides. The way to calculate the area of a trapezium is this:
- Half the sum of the parallel sides
- Multiply the perpendicular height between them
In this case, 4 and 2 are parallel, so we add them together (4 + 2 = 6) then we divide by two (6 ÷ 2 = 3). Then we multiply our answer by the perpendicular length between the two parallel sides (assuming the side on the left is at a right-angle, 3 x 2 = 6).
Method 2:
Calculate this shape as a rectangle + a triangle. If you split the shape so the pointy bit on the right becomes a triangle and the left becomes a square, you can calculate the area without knowing the formula for calculating a trapezium (see above ^).
- Area of the square / rectangle = length x width = 2 x 2 = 4
- Area of the triangle = 1/2 x length x width = 2 x 2 x 1/2 = 4 x 1/2 = 4 ÷ 2 = 2
Then we add the two areas together (4 + 2 = 6).

Answer:
A.) P^2 - 10p + 24 = 0
B.) 6 or 4 dollars
Step-by-step explanation:
Given that a company’s weekly revenue, in thousands, is modeled by the equation
R = -p2 + 14p,
where p is the price of the product it makes. The company is considering hiring an outside source to distribute its products, which will cost the company 4p + 24 thousand dollars per week.
If the company want to break even, the cost of hiring distributors will be equal to the revenue per week.
Therefore,
-P^2 + 14p = 4p + 24
Collect the like terms
-P^2 + 14p - 4p - 24 = 0
-P^2 + 10p - 24 = 0
Multiply all by minus sign
P^2 - 10p + 24 = 0
B.) To find P, factorize the equation above.
P^2 - 10p + 24 = 0
- 6 x - 4 = 24 and - 6 - 4 = 10
P^2 - 4p - 6p + 24 = 0
P( p - 4 ) - 6( p - 4 )
P - 6 = 0 or p - 4 = 0
P = 6 or 4
Substitute both back into the equation to test their authenticates
When p = 6
6^2 - 10(6) + 24 = 0
When p = 4
4^2 - 10(4) + 24 = 0

Raymond normally has a snack consisting of ten 12-calorie crackers. How many 20-calorie cookies would he have to eat to consume the same number of calories?
Work Shown:
He eats ten 12-calorie crackers, so that is 10*12 = 120 calories total
If x is the number of 20-calorie cookies, then the total number of calories here is 20x. We want this to be 120, so,
20x = 120
x = 120/20 .... divide both sides by 20
x = 6
He must eat six 20-calorie cookies to get 120 calories total
Answer: 6 cookies
Step-by-step explanation:
First, multiply 10*12 to see how many calories he normally eats.
10*12 = 120
Then, divide by 20 to see how many cookies he can eat to keep the same number of calories.
120/20 = 6

is the square root of 29 rational or irrational?
Answer:
irrational
Step-by-step explanation:
rational - a number that can turn into a fraction (you could do this with a perfect square)
Irrational - a number that cannot be expressed as a fraction
The square root of 29 is an irrational number because it can not be expressed as a fraction.
To determine whether the square root of 29 is rational or irrational, we need to check if it can be expressed as a fraction (ratio) of two integers.
Assuming that the square root of 29 is rational, we can represent it as √29 = a/b, where a and b are integers with no common factors other than 1, and b is not equal to 0.
Squaring both sides of the equation (√29)² = (a/b², we get 29 = (a²)/(b²).
This implies that 29 is equal to the ratio of two integers (a²)/(b²), which means that 29 can be expressed as a fraction. However, this is not true because 29 is a prime number and cannot be written as a fraction of two integers.
Therefore, the square root of 29 cannot be expressed as a fraction and is therefore irrational.
Hence, the square root of 29 is an irrational number.

Murray’s father deposited $6,000 of his savings into two accounts. One account earns 1.5 percent interest, and the other account earns 2.5 percent interest. At the end the year, the interest in the account that earned 2.5 percent was $110.00 more than the other account. Which system represents the amounts of money, x and y, that was put into each account? x + y = 6,000. 0.025 x + 0.015 y = 110. x + y = 6,000. 0.25 x + 0.15 y = 110. x + y = 6,000. 0.025 x minus 0.015 y = 110. x + y = 6,000. 2.5 x minus 1.5 y = 110.
Answer:
x + y = 6,000
0.025x - 0.015y = 110
Step-by-step explanation:
Let x and y = amount of money deposited in each account respectively
Total savings=$6,000
Therefore
x+y=6000
x account earns 1.5 percent interest, and y account earns 2.5 percent interest.
1.5% * y
=(1.5/100)y
=0.015y
2.5% * x
=(2.5/100)x
=0.025x
The interest in the account that earned 2.5 percent was $110.00 more than the other account.
This means the difference between 0.025x account and 0.015y account=110
0.025x-0.015y=110
x + y = 6,000
0.025x - 0.015y = 110
Answer: The answer is C: x + y = 6,000. 0.025 x minus 0.015 y = 110.

Answer:
The distance Ted will run in 285 minutes is 60 km
Step-by-step explanation:
The information in the question states as follows;
The distance Ted can run in 95 minutes = 20 km
Therefore, from the equation of speed, we have;
Speed = Distance covered ÷ Time taken
Ted speed, s = 20 km/(95 minutes) = 4/19 = 0.21 km/minute
Therefore, the distance, d Ted will cover in 285 minutes is given as follows;
d = Speed × Time = 0.21 km/minute × 285 minutes = 60 kilometres
The distance Ted will run in 285 minutes = 60 kilometres.

Answer:
(-2, 21) and (8, 8)
Step-by-step explanation:
Use the two coordinate pairs (-2, 21) and (8, 8). As we go horizontally from the first to the second, the run (change in x) is 10 and the rise (change in y) is -13. Thus, the slope of the line through (-2, 21) and (8, 8) is m = rise / run = -13/10.

Answer:
[tex]\boxed{\angle RQS = 56 \ degrees}[/tex]
[tex]\boxed{\angle SRT = 56 \ degrees}[/tex]
Step-by-step explanation:
A) ∠QRS = 90 degrees (The angle of the triangle opposite to the diameter is always 90)
Given that QR = 68 degrees
So,
∠RSQ = [tex]\frac{1}{2} (QR)[/tex]
∠RSQ = 68/2
∠RSQ = 34 degrees
Now, Finding ∠RQS
∠RQS = 180-90-34
∠RQS = 56 degrees
B) ∠SRT = ∠QRS - ∠QRT
=> ∠QRS = 90 (Mentioned above) , ∠QRT = 56 (Given)
So,
∠SRT = 90-56
∠SRT = 34 degrees
