Answers
Answer:
divide 54 by 9, and you get 6. this is because for every 5 sam gets bethan will get 4. if you add, that, you will get the total amount for 1 share. since there are 6 shares, you multiply that by the amount of eros sam and bethan gets each share.

Why does sin30° equal 1/2?
Answers
Step-by-step explanation:
it's easy to prove in any right triangle with a 30° angle, the side opposite to that angle is half the hypotenuse. CA (1/2)BC, CA/BC=1/2
Step-by-step explanation:
Take an equilateral triangle of side.
Bisec it through a vertex and the midpoint of the opposite side.
You now have two right-angled triangles with angels 30° , 60°, 90° with the edge opposite the 30° of length 1/2 and hypotenuse 1. So
sin (30°) = 1/2/1= 1/2.
Answer: The right angled triangle you describe has angels of 45 degrees, not 30 degrees.
What you proved is sin 45 = 1\2 , which is correct.

Inequality is [tex]10x+18\leq 238[/tex]
Subtract [tex]18[/tex] from both side of the inequality
[tex]\Rightarrow 10x+18-18\leq 238-18\\\Rightarrow 10x\leq 220[/tex]
divide both sides by 10
[tex]\Rightarrow \frac{10x}{10}\leq \frac{220}{10}\\\Rightarrow x\leq 22[/tex]
Therefore, maximum value of x can be 22 i.e. at most 22 days

Lula is reading a book for school that is 175 pages long. So far, she has read 50 pages. She can read 25 pages per hour. How many hours will it take her to finish the remainder of the book? Which answer choice best represents the unknown quantity in this problem ?
Answers
Answer: 5 hours
Step-by-step explanation:
She has already read 50 pages so we need to deduct that to calculate the answer:
= 175 - 50
= 125 pages left
She can read at a speed of 25 pages per hour. The number of hours it would take to read the remainder of the book would therefore be:
= 125 pages / 25 pages per hour
= 5 hours

The length of one diagonal of a rhombus is 8 cm. The area of the rhombus is 72 cm2. What is the length of the other diagonal of the rhombus?
Answers
Answer:
18 cm
Step-by-step explanation:
From the question above,
Area of a rhombus
A = d₁d₂/2.................. Equation 1
Where A = area of the rhombus, d₁ = length of one diagonal, d₂ = length of the other diagonal
make d₂ the subject of the equation
d₂ = 2A/d₁............... equation 2
Given: A = 72 cm², d₁ = 8 cm
Substitute these values into equation 2
d₂ = (2×72)/8
d₂ = 144/8
d₂ = 18 cm.

Find two numbers whose product is 25 and whose sum is -10

A product is an answer to a multiplication problem and sum is the answer to an addition problem.
25 is the product, and -10 is the sum.
Factors of 25 is 5 and 5.
-5+-5=10.
But two negatives multiplied equals a positive.
-5 x -5=25
-5 + -5 = 10
---
hope it helps
Answer:
The two numbers are -5 and -5
Step-by-step explanation:
Let x and y be the two numbers respectively
xy = 25 --(1)
x + y = -10 --(2)
From (1), x = 25/y [You get x in terms of y]
Sub x = 25/y into (2)
25/y + y = -10 [Equation (2) is x + y = -10, but you got x = 25/y]
[Multiple the whole equation by y]
25 + y^2 = -10y
y^2 + 10y + 25 = 0 [This is a quadratic equation if you don't know]
y = -5
Sub y = -5 into (1)
x = -5

Answers
Answer:
53.44 cubic meters
Step-by-step explanation:
A cylindrical oil drum is 2.1 meters high and has a radius of 0.9 meters. How many cubic meters of oil can the drum hold? (volume)
Volume of a cylinder = π × r² × h
r = 0.9 meters
h = 2.1 meters
= π × (0.9m)² × 2.1m
= 53.44 cubic meters
Therefore, the volume of the cylindrical oil drum = 53.44 cubic meters

A right angled triangle is a triangle (has three sides and three angles) in which one of the angles measure 90°.
Trigonometric ratios is used to show the relationship between the sides of the right angled triangle and its angles.
Let h represent the height of the cliff. Let θ = 90 - 49 = 41°. Hence:
tan(41) = 17/h
h = 17 / tan(41) = 19.6 m
Therefore the cliff is 19.6 m tall
