help :rewrite 2.267 repeating 67 as a simplifed answer
Answer:
449/198 or 2 53/198
Step-by-step explanation:
2. 2676767 = x
10x= 22. 67676767
1000x= 2267. 676767
1000x-10x= 2267.676767- 22.67676767
990x= 2245x= 2245/990x= 449*5/5*198x= 449/198 x= 2 53/198Answer:
Step-by-step explanation: First, create an equation that represents the repeating decimal that you want to convert to a fraction
x = 2.267267.... (1)
There are 3 repeating decimals, multiply both sides of the equation by 103 = 1000 so that both equations have the same repeating digits to the right of the decimal point
1000x = 2267.267267... (2)
Subtract the equation (1) from equation (2)
1000x
x =
= 2267.267267...
2.267267...
999x = 2265
Solve for the x in the equation to determine the equivalent fraction.
x =
2265
999
Since the greatest common factor of 2265 and 999 is 3, we can simplify the fraction and show the same amount
2265
999
=
2265 ÷ 3
999 ÷ 3
=
755
333
Therefore, 755/333 is simplified fraction of 2.267 repeating. Since this is an improper fraction, converted to mixed number is:
755
333
= 2
89
333
Therefore, 2.267 repeating as a fraction is 755/333 and It is written as 2 89/333 in mixed number form.

Answer:
976cm^2
Step-by-step explanation:
Surface area:
Ara of cross section x 2 = 1/2 x 2 x 14 x 24 = 14 x 24 = 336
Area of base = 14 x 10 = 140
area of slope x 2 = 25 x 10 x 2 = 500
Total surface area = 500+140+336 = 640 + 336 = 973cm^2
Answer:

Area of triangle: 1/2bh
Area of rectangle b×h
2 Triangular ends 12×14=168 each So 336
2 sides 10×25=250 each So 500
1 base 10×14=140
Add: 140+500+336=976 square centimeters

A shop sells posters in different sizes. The height (h) and width (w) of each poster are linked by the formula h=2.5w -5 What is the width of a poster that is 10 cm high?
Answer: 6 cm
Step-by-step explanation:
Hi, to answer this question we simply have to substitute h=10 (height) in the formula given:
h=2.5w -5
Replacing:
10= 2.5w-5
Solving for w (width)
10+5=2.5w
15 =2.5w
15/2.5=w
w =6 cm
In conclusion, the width of a poster that is 10 cm high is 6 cm.

The system of the equation that represents the given condition will be x + y = 7 and y = x + 3. And the solution is (2, 5).
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The sum of x and y is 7. The value of y is three more than the value of x. Then the equation is given as,
x + y = 7 ...1
y = x + 3 ...2
From equations 1 and 2, then we have
x + x + 3 = 7
2x = 4
x = 2

Identify intervals on which the function is increasing, decreasing, or constant. g(x) = 4 - (x - 6)2 (5 points)
Answer:
g(x) is always decreasing
Step-by-step explanation:
Step 1: Distribute
g(x) = 4 - (2x - 12)
g(x) = 4 - 2x + 12
Step 2: Combine like terms
g(x) = -2x + 16
Since the line is linear and has a negative slope, it will always decrease when you input either a positive or negative x value. The output y will go lower.

Answer:
11/8 or, 1 and 3/8
Step-by-step explanation:
First, we have to make both the denominators the same. In this case, we can multiply 3/4 by 2, to make 4, the denominator, into 8. What we do to the denominator, we must do to the numerator! So, we multiply 3 by 2, and get 6!
Now we have, 5/8 + 6/8, which equals 11/8! Which can also be simplified to 1 and 3/8 (because the numerator is larger than the denominator)
Hope this helps! :)
What are the asymptote and the Y intercept of the function shown in the graph f(x)=3(0.2)^x+2
the asymptote is y = 2 and the y - intercept is (0,5)
What is asymptote function?An asymptote is a line that the graph of a function approaches as either x or y go to positive or negative infinity. There are three types of asymptotes: vertical, horizontal and oblique. That is, as approaches from either the positive or negative side, the function approaches positive or negative infinity.
According to the question
The function reaches the y-axis at the point (0,5).
The asymptote is the line that the function follows but never quite reaches. In this case, the function follows the path of y = 2. However, it never exactly fits the line.
The y-intercept is (0,5) and the asymptote is y = 2. The answer, then, is B.
Hence, the asymptote is y = 2 and the y - intercept is (0,5)

Which of the following theorems verifies that ABC~WXY?
Answer:
ABC~WXY by AA
Step-by-step explanation:
In ΔABC
∠B = 90°
∠A = 27°
To Find ∠C
Angle sum property: The sum of all angles of triangle is 180°
∠A+∠B+∠C=180°
27°+90°+∠C=180°
∠C=180°-117°
∠C=63°
In ΔWXY
∠X = 90°
∠Y = 63°
We will use angle sum property
So, ∠W+∠Y+∠X=180°
90°+63°+∠W=180°
∠W=180°-(90°+63°)
∠W=27°
So, ∠A=∠W
∠B =∠X
∠C = ∠Y
So, ABC~WXY by Angle - Angle property.
Hence ABC~WXY by AA

Step-by-step explanation:
Given
Initially, he drank 3 pints of water
Then, [tex]1\frac{1}{2}[/tex] more cups
Required
How many cups did Ian drink altogether
This question can be solved by adding the size of water he drank during the hike and when he got home
i.e.
[tex]Total = 3\ pints + 1\frac{1}{2} cups[/tex]
But the answer should be in cups;
So, number of pints has to be converted to number cups
Given that 1 pint = 2 cups;
3 pints will be 3 * 2 cups
3 pints = 6 cups;
So,
[tex]Total = 3\ pints + 1\frac{1}{2} cups[/tex]
[tex]Total = 6\ cups + 1\frac{1}{2} cups[/tex]
[tex]Total = 7\frac{1}{2} cups[/tex]
Altogether, he drank [tex]7\frac{1}{2} cups[/tex] of water

What is f(x)=x2-8x+11 written in vertex form
What is the value of x?
Answer:
x = 55 degrees
Step-by-step explanation:
Angles of a triangle add up to 180 degree so we'll simply subtract the rest of the angles from 180 to get the value of x.
=> x = 180-75-50
=> x = 55 degrees
Answer:
55
Step-by-step explanation:
The sum of angles triangles will always be 180
75 + 50 is 135
180-35 = 55
Which of the following is an example of dependent events? A. Drawing a jack from a standard deck of cards and then drawing a six without replacing the jack B. Winning the lottery and getting struck by lightning C. Spinning a 5 on a spinner and getting tails from flipping a coin D. Owning a dog and being in the school chorus
Answer: A. Drawing a jack and drawing a six without replacement
Step-by-step explanation:
A Dependent event means the outcome of one event affects the outcome of the other event.
Options B, C, and D:
The first event is completely unrelated to the second event so those options are Independent events.
Option A:
The first event uses 52 cards. The second event only has 51 cards remaining because we did not replace the first card. The probability of the second event IS affected by the first event so this is a Dependent event.
Note: If the card was replaced before drawing the second card, then it would be an Independent event.
The example for dependent events is (A) Drawing a jack from a standard deck of cards and then drawing a six without replacing the jack.
What are Dependent Events?If the probability of one event of two events is affected by another one then that two events are called dependent events of one another.
What is Probability?The probability of an event is the ratio of the favorable cases for that event to the total number of possible cases under that event.
Here analyzing the given choices we get,
(A) If we draw a jack from a standard deck of cards that is containing 52 cards.
And then we draw a six replacing without that jack card then it affects the probability as the total number of cards for this event reduces from 52 to 51.
So these two events are dependent events.
(B) Winning a lottery and getting struck by lighting are completely two different events from a different field, so they are independent.
(C) Spinning a 5 on a spinner cannot affect getting tails from flipping a coin. So they are not dependent on events.
(D) Owning a dog cannot affect being in the school chorus so they are independent (not dependent).
Hence the correct answer is (A).
