Rounding to nearest tenth:
i) if number in 100th place is 5,6,7,8 or 9, then add 1 to number in the tenth place and after adding remove all the digits right to it.
EG: 4.567 = 4.6
ii) if number in 100th place is 0,1,2,3 or 4, then write down number in the tenth place as it is and then remove all the digits right to it.
Eg: 4.523 = 4.5

What is the Pythagoras theorem?Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a² + b² = c².
Given here, Sin C = x/1 and therefore Hypotenuse = 1 and perpendicular =x
thus Base=1-x² by phytogaraen theorem.
Thus Sin A=1-x² /1
Hence, Sin A= 1-x² is the correct answer.

What is the inverse of f(x) = 3x + 6 and is it a function?
answer:
the answer would be x-6/3, yes
The inverse of the function f(x) = 3x + 6 is f^-1(x) = (x - 6) / 3. This inverse is also a function, as it satisfies the vertical line test.
Explanation:The inverse of a function f(x) is typically denoted as f-1(x). To find the inverse of the function f(x) = 3x + 6, you follow two main steps: firstly, replace f(x) with y, yielding y = 3x + 6; secondly, swap x and y to get x = 3y + 6 and solve for y to get the inverse function.
Getting the inverse starts by subtracting 6 from both sides of the equation, which gives x - 6 = 3y.
Dividing through by 3 gives (x - 6) / 3 = y, or equivalently, y = (x - 6) / 3. So, the inverse of the function is f-1(x) = (x - 6) / 3.
This inverse is indeed a function as it passes the vertical line test. That is, any vertical line drawn through the graph of this function will touch the graph at no more than one point, showing that for every input x, there is exactly one output y.

Paula designed a three-dimensional scale model of a department store. The volume of
the scale model was 35 cubic feet. The ratio of the dimensions of the model to the
dimensions of the store was 1:20. Determine the volume of the actual department
store that Paula planned to build.
Answer:
V = 280000 cubic meters
Step-by-step explanation: Given that the volume of the scale model was 35 cubic feet. The ratio of the dimensions of the model to the
dimensions of the store was 1:20.
Let the volume of the actual department store that Paula planned to build be V. Then
35/V = (1/20)^3
35/V = 1/8000
Cross multiply
V = 8000 × 35
V = 280000 cubic meters
Answer: The volume of the actual department store is 280,000 cubic feet
Step-by-step explanation: The question has provided the volume of the model built by Paula, and that is 35 cubic feet. The volume of a three sided solid is given as;
Volume = L x W x H
This can also be conveniently expressed as;
Volume = L³ (which implies that the solid has all sides measuring the same for simplicity's sake)
However, given that the ratio of the model to that of the actual store is 1:20, we simply use the given ratio to substitute for the value of the side of the actual store, hence we now have dimension as;
Volume = L³
35 = L³
Add the cube root to both sides of the equation
∛35 = L
The dimension of the actual store which is an enlargement by a ratio of 1:20 now becomes;
Actual store = 20 x L
Actual store = 20 x ∛35
Actual store = 20 x 3.27106631018859
Actual store = 65.42132620377179
Therefore the volume of the actual store is given as;
Volume = L³
Volume = 65.42132620377179³
Volume = 280000
Therefore the volume of the actual store is 280,000 cubic feet

Find the volume of the composite solid. Round your answer to the nearest tenth.
Answer:
67.0 cm³
Step-by-step explanation:
The composite shape is a hemisphere of radius 2 atop a cylinder of height 4 and radius 2. The volume formulas for a cylinder and a sphere can be used to find its volume. (Dimensions are in centimeters.)
HemisphereThe formula for the volume of a hemisphere is half that for the volume of a sphere:
V = (1/2)(4/3πr³) = 2/3πr³
For a radius of 2 cm, the volume is ...
V = 2/3π(2 cm)³ = 16/3π cm³
CylinderThe formula for the volume of a cylinder is ...
V = πr²h . . . . . . for radius r, height h
For the given dimensions, the volume is ...
V = π(2 cm)²(4 cm) = 16π cm³
TotalThe total volume of the solid is the sum of these volumes:
total = hemisphere volume + cylinder volume
total = ((16/3)π +16π ) cm³ = (64/3)π cm³ ≈ 67.0 cm³
The volume of the composite solid is about 67.0 cm³.

Sali throws an ordinary fair 6-sided dice once.
a) what is the probability she gets a 6?
Tim throws the same dice twice.
b) what is the probability he gets a 6 on both throws?
Tony throws the dice once. He also throws a coin to get Heads or Tails. Two of the outcomes are 1H and 2 H.
c) List all the other outcomes in the same format.
1H. 2H
Answer:
[tex]a=p=\frac{1}{6}\\\\b. \ p=\frac{1}{12}\\\\c.\ 1H,1T,2H,2T,3H,3T,4H,4T,5H,5T,6H,6T[/tex]
Step-by-step explanation:
a. A fair dice has 6 sides with unique identities.
-The sample space of one throw is 6 and each face has an equal chance of showing up.
-The probability of a 6 is calculated as:
[tex]p(six)=\frac{1}{6}\\\\or \ =0.1667[/tex]
Hence, the probability of a 6 is [tex]\frac{1}{6}[/tex]
b.A fair die has 6 unique faces.
-Two throws will have a sample space of 12.
-Each face has an equal probability of appearing twice.
-The probability of a 6 on both throws is:
[tex]P(six)=2\times \frac{1}{6}\\\\=\frac{1}{12}[/tex]
c. A coin has 2 sides(head, tail) and a die has 6 sides.
-The total sample space for the simultaneous throw of a coin and die is 12.
-The resultant sample space is :

Use the Pythagorean theorem to find a whole number estimate of the length of the unknown side of the right triangle. The length of the unknown side of the triangle is approximately cm.
Answer:
12 cm
Step-by-step explanation:
Leg of one side = 5 cm
Hypotenuse = 13cm
According to the theorem,
A^2 + B^2 = C^2
5^2 + B^2 = 13^2
25 + B^2 = 169
Subtract 25 form both sides,
B^2 = 169 - 25
B^2 = 144
B = sqrt( 144 )
B = 12
