Answer:
87 pages are filled with stamps.
Step-by-step explanation:
We need to know how many stamps are in the album. Since it can hold 500 but is missing 13%, we can say that it is 87% (100-13=87) complete.
500*0.87=435
The album has 435 stamps.
A page can hold 5 stamps. Thus, 435/5=87
To find out how many stamp album pages are filled, calculate the total number of album pages, determine the number of empty stamps at 13%, and subtract the number of empty pages from the total to get 87 filled pages.
The mathematics problem presented asks how many pages of a stamp album are filled with stamps if 13% of the album is empty. To solve this, we need to calculate the total number of stamps that can fit in the album and determine how many stamps equivalent to 13% of the album are missing. With 500 stamps able to fit in the album and each page holding 5 stamps, we can first find out the total number of pages in the album.
Total number of pages = Total stamps / Stamps per page = 500 / 5 = 100 pages
Next, we calculate 13% of the total number of stamps to find out how many stamps are missing:
Number of empty stamps = Total stamps [tex]\times[/tex] 0.13 = 500 [tex]\times[/tex] 0.13 = 65 stamps
Now, we find out the number of empty pages:
Number of empty pages = Empty stamps / Stamps per page = 65 / 5 = 13 pages
Thus, the number of filled pages:
Total pages - Empty pages = 100 - 13 = 87 filled pages.

What is the probability of spinning green on the first spinner and blue on the second spinner?
The probability of spinning 'green' on the first spinner and 'blue' on the second spinner can be calculated by multiplying the individual probabilities assuming that they are independent events.
Explanation:The probability of getting 'green' on the first spinner and 'blue' on the second spinner can be calculated by multiplying the individual probabilities if the two events are independent. If the first spinner has 'g' green out of 't' total possible outcomes and the second spinner has 'b' blue out of 's' total outcomes, the first probability would be 'g/t' and the second one 'b/s'. Hence, the probability of spinning 'green' on the first and 'blue' on the second would be (g/t) * (b/s).
For instance, if the first spinner has 2 green areas out of 10 total (2/10=0.2) and the second spinner has 3 blue areas out of 10 (3/10=0.3), then the probability of spinning 'green' first and 'blue' second would be 0.2*0.3=0.06 or 6%. Remember that the aforementioned explanation assumes that the outcomes from the two spinners are independent, that is, the result from the first does not affect the result from the second.

The probability of spinning green on the first spinner and blue on the second spinner is 1/9.
To calculate the probability of independent events, we need to multiply the probabilities of each event occurring separately.
Assume the first spinner has equal sections for each color: red, blue, and green.
Thus, the probability of spinning green is 1/3.
Similarly, assume the second spinner has equal sections for each color: red, blue, and green.
Thus, the probability of spinning blue is 1/3.
Since the spins are independent events, the overall probability is calculated by multiplying these probabilities:
P(Green on first) * P(Blue on second) = 1/3 * 1/3 = 1/9

Which other expression has the same value as (-14) - 8?
An expression that has the same value as (-14) - 8 is (-14) + (-8), both of which equal -22.
Explanation:The question is about finding an expression that is equivalent to (-14) - 8. When we subtract a positive number from a negative number, we move further to the left on the number line, making the number more negative. Therefore, (-14) - 8 is the same as adding the opposite of 8, which is -8, to -14, giving us -22. Another way to see it is moving 8 units to the left from -14 on a number line.
Thus, an equivalent expression might be the subtraction of the negative of 8, which is (-14) + (-8). We add the two negative numbers together following the rule that adding two negative numbers results in a negative sum. In this case, (-14) + (-8) is also -22.

A skating rink charges a group rate of $9 plus a fee to rent each pair of skates. A family rents 7 pairs of skates and pays a total of $30. What does "X" represent?
In the problem, 'X' denotes the cost to rent each pair of skates. Setting up and solving the equation, 9 + 7X = 30, we find 'X', the cost per pair, is $3.
Explanation:In this problem, 'X' represents the cost to rent each pair of skates. The problem refers to a situation where a skating rink charges $9 for a group rate and an additional fee for every pair of skates rented. According to the provided information, a family who rents 7 pairs of skates pays a total of $30. We can set up an equation to solve for 'X.'
The equation is 9 + 7X = 30, where X is the cost per pair of skates.
To solve this equation, you have to subtract 9 from both sides, getting 7X = 21. Afterward, you divide both sides by 7, and you get X = 3. Therefore, 'X' corresponds to $3, the cost per pair of skates.

The value of the trigonometric relation cot ( sin⁻¹ ( -1 ) ) = 0
What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the trigonometric relation be represented as A
Now , the value of A is
A = cot ( sin⁻¹ ( -1 ) ) be equation (1)
On simplifying , we get
The value of ( sin⁻¹ ( -1 ) ) = -π/2
where sin (-θ) = -sin (θ)
So , A = cot ( -π/2 )
From the trigonometric relations ,
cot (-θ) = -cot (θ)
cot ( -π/2 ) = 0
Hence , the trigonometric relation is solved

Answer:
I think its b) y=2x-3
Step-by-step explanation:
The answers are all in slope-intercept form: y= mx+b. In slope-intercept form m represents the slope and b represents the y-intercept. (Its confusing, I know).
The slope here is 2/1 or 2. Considering rise/run we can see that the line goes up (rise) two (2) points and over (run) one (1).
Now we have y= 2x+b, we just need the y-intercept.
Looking at the y-axis, the line crosses at (0, -3). So the y-intercept is -3!
That gives us y=2x-3

What is the volume of a square pyramid if the perimeter of the base is 44 in and the height is 19 in.? Round to the nearest tenth
Answer:
The volume of the square pyramid is 766.3 in³ approximately.
Step-by-step explanation:
To find the volume of the square pyramid whose perimeter of the base is 44 in and a height of 19 in, we will follow the steps below:
Write down the formula for calculating volume of the square pyramid
v=A(h/3)
where v is the volume, A is the area of the base and h is the height.
From the question given, the perimeter of the base is 44.
If the perimeter of the base is 44, then we can say;
4l = 44
Dividing both-side by 4
l = 11
The length of the base = 11
Area of the base = l² =11² = 121 in²
Als from the question given, height is 19 in.
we can now proceed to plug in our values into the formula
v=A(h/3)
v = 121 (19/3)
v≈766.3 in³ to the nearest tenth.
Therefore, the volume of the square pyramid is 766.3 in³ approximately.
Harrison plays a game in which he uses a net to catch balls that are randomly launched from holes in the ground. The height of one ball after t seconds is represented by the function f(t) = –16t2 + 20t. After how many seconds does the ball return to the ground? Round to the hundredths place as needed. seconds
Answer:
The ball will return to the ground after 1.25 seconds
Step-by-step explanation:
Given
f(t) = -16t² + 20t
Required
After what time (in seconds) does the ball return to the ground?
Function f(t) is a function of time and it represents the displacement of the ball.
For the ball to return to the ground, it means the displacement is 0.
So, we have f(t) = 0.
Substitute 0 for f(t) in the above, we have
0 = -16t² + 20t ---- Factorize
0 = -4t(4t - 5) ---- Reorder
-4t(4t - 5) = 0
This above expression can be splitted to;
-4t = 0 or 4t - 5 = 0
For -4t = 0,
divide through by -4
This will give t = 0
For 4t - 5 = 0,
Collect like terms
4t = 5 + 0
4t = 5
Divide through by 4
t = 5/4
t = 1.25
So, we have that
t = 0 or t = 1.25
But t can't be 0 because the ball has already traveled some distance.
So, t = 1.25
Hence, the ball will return to the ground after 1.25 seconds
