A triangle has sides of length 11cm, 10 cm, and 9cm.
Calculate the largest angle in the triangle.
Answer: In right angled triangle
Length of square of biggest side it's equal to length sum of square of two other sides
(11)² = (9)² + (10)²
121 = 81 + 100
121 = 181
So it is not a right angled triangle

suppose the school parents club compited a cookbook. One company charges $750 to make a master copy and 25 for additional copy the total selling price depends on how many copies are ordered write a function rule and create a table of values to graph the value how much will you save per book by ordering 400 books instead of 100 books
The function rule for the total cost of the cookbook is C(x) = 750 + 25x, where x is the number of copies ordered.
# of Copies Ordered Total Cost
100 875
200 1000
300 1125
400 1250
If 400 copies are ordered instead of 100, the total cost would be $1250 instead of $875, saving $375 per book.

The total number of visitors to the zoo that day was 47,750, with 6,780 adults and 40,680 children.
Let a = number of adults
Let c = number of children
a + c = 47,750
c = 6a + 270
Substitute c in the first equation:
a + 6a + 270 = 47,750
7a = 47,480
a = 6,780
Substitute a in the second equation:
c = 6(6,780) + 270
c = 40,680
The total number of visitors to the zoo that day was 47,750, with 6,780 adults and 40,680 children.

a conical salt spreader is spreading salt at a rate of 3 cubic feet per minute. the diameter of the base of the cone is 4 feet and the height of the cone is 5 feet. how fast is the height of the salt in the spreader decreasing when the height of the salt in the spreader (measured from the vertex of the cone upward) is 3 feet? give your answer in feet per minute.
Answer:
-25/(12π) ft/min ≈ -0.663 ft/min
Step-by-step explanation:
You want the rate of change of height of the salt in a cone with height 5 ft and diameter 4 ft, filled 3 ft up from the vertex, and decreasing in volume at the rate of 3 cubic feet per minute.
Rate of change of heightThe rate of change of height is the rate of change of volume, divided by the surface area.
Surface areaThe given cone dimensions tell you the radius is 2/5 of the height of the cone, so the radius of the surface when it is filled to a depth of 3 ft is ...
r = (2/5)(3 ft) = 1.2 ft
The area of the surface is the area of a circle with this radius:
A = πr² = π(1.2 ft)² = 1.44π ft²
ApplicationThen the rate of change of height is ...
h' = V'/A
h' = (-3 ft³/min)/(1.44π ft²) = -25/(12π) ft/min ≈ -0.663 ft/min

suppose that you are rolling a six sided dice. let a = get a 3 what is p(ac)?
Take a six-sided dice for example.
If we let a, then a = 3.
Write about p (ac).
A six-sided die will obviously be rolled.
Obtaining a number fewer than three is required for letter A.The initials "AC" stand for "Anything which is not in A" on a die or "A-Complement".
A = 3 can be used to calculate a number less than 3 or a number greater than 3.
Taking into account that the possibilities 1, 2, 4, 5, and 6 are all in AC.
If we take the ratio of successful outcomes to overall outcomes, we have a chance.
P(AC) = 4/6 = 2/3
P(AC) is thus equal to 2/3.

the perimeter of a triangle is 49 feet. one side of the triangle is 7 feet shorter than the second side. the third side is 4 feet shorter than the second side. find the length of each side
the perimeter of a triangle is 49 feet. The triangle's one side is seven feet shorter than its other. the length of each side , Second side: 16 feet, First side: 9 feet,Third side: 12 feet
To find the length of each side of the triangle, we need to start by looking at the perimeter, which is 49 feet.
Perimeter = 49 feet
Second side = 49 - 4 = 45 feet
First side = 45 - 7 = 38 feet
Third side = 45 + 4 = 49 feet
We know that the third side is 4 feet shorter than the second side, so we can subtract 4 feet from the perimeter to find the length of the second side, which is 16 feet. Then, we know that the first side is 7 feet shorter than the second side, so if we subtract 7 feet from the second side we can find the length of the first side, which is 9 feet. Finally, to find the length of the third side, we add 4 feet to the second side, which gives us 12 feet. Therefore, the length of each side of the triangle is 9 feet, 16 feet, and 12 feet.

We can find the slope of the second line using the formula
[tex]m_{2}=-\frac{1}{m_{1} }[/tex], where m2 is the slope of the second line and m1 is the slope of the first.
Thus, since 1/9 is the slope of the first line, we have

Since the slope intercept form is y = mx + b, where b is the y-intercept, we need to it in the second line by plugging in (3, 4) for x and y and -9 for m:

A t-test cannot cover more than one group. This has to do with the underlying method used to calculate the test value.
Explain about t-test?
The t-test is designed to compare the means of two populations based on the means of the two samples. (any sample from either population).
The most important observation is that the t-test computes the difference between two sample means.
If you have trouble understanding 'variance', you can use the word standard deviation from the previous text to get your points.
In other words, there is more than one difference between the groups, but we want one measure of Total Difference Between Groups. The t-test cannot do that.
So the procedure for groups of three or more is: Run ANOVA first. As a second step, if you have reason to believe that differences exist (based on this test), you can use the t-test to determine where those differences lie.
A t-test cannot cover more than one group. This has to do with the underlying method used to calculate the test value.

This is calculated by multiplying the cost of each game (25 cents) by the number of times Larry will have to play (16 times) to last 4 minutes. It will cost Larry $1.00 to last 4 minutes before he is knocked out.
Larry started playing a video game and was knocked out in 30 seconds. He then decided to play again and this time he was able to play 30 seconds longer than the previous game. He kept repeating this and was able to play 30 seconds longer each time. Since it cost him 25 cents to play each game, it will therefore cost him $1.00 to last 4 minutes before he is knocked out. This is calculated by multiplying the cost of each game (25 cents) by the number of times Larry will have to play (16 times) to last 4 minutes. Therefore, 25 cents x 16 = $1.00.

The 3 : 7 ratio into which the amount of money is shared by Moira and Non where Non gets $28 more than Moira, indicates;
a) The total amount of money they share is $70
b) The amount Moira gets is $21, while the amount Non gets is 3 : 7
What is a ratio?A ratio is a quantitative expression that specifies the number of times a value is contained within another value.
The ratio by which Moira and Non share the money = 3 : 7
The amount Non gets = 28 + The amount Moira gets
Let x represent the amount Moira gets, therefore;
The amount Non gets = 28 + x
The specified ratio indicates;
[tex]\dfrac{x}{28 + x} = \dfrac{3}{7}[/tex]
7·x = 3 × (28 + x)
7·x = 84 + 3·x
7·x - 3·x = 84
4·x = 84
x = 84 ÷ 4 = 21
x = 21
The total amount of money = The amount Moira gets + The amount Non gets
Therefore; The total amount of money = x + 28 + x = 2·x + 28
2·x + 28 = 2 × 21 + 28 = 70
The total amount of money = $70
