Answer:
The cost of 1 meal, 1 night and 1 ski lesson is $ 160.
Step-by-step explanation:
Let the nights be N , meals be M, ski lesson is S.
According to the question
2 N + 3 M + S = 310.....(1)
2 N + 5 M + 2 S = 380 ..... (2)
N + 2 M = 150 .....(3)
By solving (1), (2) and (3) we get
N = $ 110, M = $ 20, S = $ 30
So, the cost of 1 night, 1 meal, 1ski lesson is
1 x 110 + 1 x 20 + 1 x 30
= 110 + 20 + 30
= $ 160
The volume of this sphere is 25500cm3. Work out the length of the radius, r . Give your answer rounded to 1 DP.
Answer:
The radius is 18.3cm
Step-by-step explanation:
Given
[tex]V = 25500cm^3[/tex]
Required
The radius, r
The volume (V) of a sphere is:
[tex]V = \frac{4}{3}\pi r^3[/tex]
So, we have:
[tex]25500 = \frac{4}{3}\pi r^3[/tex]
Solve for r
[tex]\pi r^3 = 25500 * \frac{3}{4}[/tex]
[tex]\pi r^3 = 19125[/tex]
Divide by [tex]\pi[/tex]
[tex]r^3 = \frac{19125}{\pi }[/tex]
[tex]r^3 = \frac{19125}{3.14}[/tex]
[tex]r^3 = 6090.8[/tex]
Take cube roots
[tex]r = 18.3[/tex] -- approximated

= 40°
so x = 40° (corresponding angles QP// RT)
HELP ASAP!!! Identify y.
Answer:
y=2
Step-by-step explanation:
53y–16= 90
53y=90+16
53y=106
y=106/53
y=2
Answer:
y = 2
Step-by-step explanation:
If one side of a triangle inscribed in a circle is a diameter of the circle, then the triangle is a right triangle and the angle opposite the diameter is the right angle.
Therefor
53y - 16 = 90
add 16 to both sides
53y = 106
Divide both sides by 53
y = 106/53
y = 2

Find the range of the given data set.
Answer:
5/8
Step-by-step explanation:
The range is the largest number minus the smallest number
The largest number is 1 1/4 and the smallest number is 5/8
1 1/4 - 5/8
Getting a common denominator
1 2/8 - 5/8
Borrowing from the 1 in the form of 8/8
8/8+2/8 - 5/8
10/8 - 5/8
5/8
Answer:
5/8
Step-by-step explanation:
because 1 1/4 is 5/4 then x2 which is 10/4 so now you 10/4 - 5/8 which equals 5/8 as the difference.

there are a tangent and secant line meet and the angle created is 45 degrees the large arc of the circle is 27x. solve for x and how?
Answer:
10°
Step-by-step explanation:
the minor arc BC = 2×45 = 90°
so, the major arc BC = 360-90=270°
27x = 270°
x = 270/27 = 10°

15 years from now Ravi's age will be 4 times his present age what is Ravi's present age
Answer:
Ravi’s present age will be 5.
Step-by-step explanation:
From the given, Let Ravi’s present age is taken as "a" years.
After 15 years, his age = (a+15) years.
By the given, it is identified that the age of Ravi after 15 years is equal to the 4 times of his present age.
Given,
[tex]a+15+4a\\4a-a+15\\3a=15\\a=15/3\\a=5[/tex]
Then, it has been found that the present age of Ravi is 5 when his age after 15 years will be 4 times of his present age.

Answer:
x = 2[tex]\sqrt{35}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + b² = a² , that is
x² + 2² = 12²
x² + 4 = 144 ( subtract 4 from both sides )
x² = 140 ( take the square root of both sides )
x = [tex]\sqrt{140}[/tex] = [tex]\sqrt{4(35)}[/tex] = 2[tex]\sqrt{35}[/tex]

Three tennis balls fit snugly into a cylindrical container. Each tennis ball has a diameter of 4.5cm. What is the volume of air inside the container? (Please solve)
Answer:
Volume of air inside the cylinder = 71.6 cm³
Step-by-step explanation:
Step 1: Determine height and radius of the cylinder
Since the three tennis balls fits in closely into the cylindrical container, the height of the cylinder is equal to the sum ofnthe diameters of the three balls.
Also, the radius of the cylinder is equal to the radius of the tennis balls.
Height of cylinder = 3 × 4.5 cm = 13.5 cm
Radius of cylinder/balls = diameter of ball / 2 = 4.5 cm / 2 = 2.25 cm
Step 2: Determination of the volume of the cylinder
Volume of a cylinder = πr²h
π = 22/7; r = 2.25 cm; h = 13.5 cm
Volume of cylinder = 22/7 × (2.25 cm)² × 13.5 cm
Volume of cylinder = 214.8 cm³
Step 3: Determining the volume of the three balls
Volume of a sphere = 4πr³/3
Volume of three balls = 4πr³/3 × 3 = 4πr³
Volume of the three balls = 4 × 22/7 × (2.25 cm)³ = 143.2 cm³
Step 4: Determining the volume of air
Volume of air inside the cylinder = Volume of cylinder - volume of the three balls
Volume of air = 214.8 cm³ - 143.2 cm³ = 71.6 cm³
Therefore, volume of air inside the cylinder = 71.6 cm³

Use the drawing tool(s) to form the correct answer on the provided graph.
Plot the axis of symmetry and the vertex for this function:
h(x) = (x - 5)2 - 7.
Answer:
Step-by-step explanation:
First, you should put the axis of symetry as 5, -7 because f(x)= (x-h)^2+k and h is 5 and k is -7. the axis of symetry is x=5 because that is the "folding point" of the graph. Next, you would have to plug In 4 and 6 as your helping points to tell you where the other points of the function are going to be.
Plug 4 in and you get -6. plug 6 in and you get -6. plot the points (4, -6) and (6,-6).
Hope this helps!

-8•|2|
Absolute value means take the positive value of the number inside
-8 * +2
Multiply
-16
Find the value of x and y. Write your answers in simplest form
Answer:
x = 16, y = 8[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = [tex]\frac{1}{2}[/tex] , then
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{8}{x}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
x = 16
----------------------------------------------------------
Using Pythagoras' identity in the right triangle
y² + 8² = 16²
y² + 64 = 256 ( subtract 64 from both sides )
y² = 192 ( take the square root of both sides )
y = [tex]\sqrt{192}[/tex] = [tex]\sqrt{64(3)}[/tex] = 8[tex]\sqrt{3}[/tex]

Find the number of sides of a regular polygon if exterior angle of the polygon is:- (a) 90 (b) 45 (c) 12 (d) 4
Answer:
8 sides
Step-by-step explanation:
THE QUESTION IS NOT COMPLETE, SO A QUESTION OF THE SAME TYPE
Find the number of sides of a regular polygon if exterior angle of the polygon is 45°?
NOTE:
Sum of the exterior angles of any regular polygon is known as (360°)
But from the question,
Each exterior angle is given as( 45°)
Number of sides of a regular polygon can be computed as
(360°/Each exterior angle)
Then substitute the give value of exterior angle, we have
= (360°/45) = 8 sides
