The ratio sin 30° : tan 45º can be written in the form 1 : n.
Find the value of n.
Answer:
n = 2
Step-by-step explanation:
sin 30° = ½
tan 45° = 1
then
sin 30° : tan 45° = 1 : n
½ : 1 = 1 : n
n = 2
The value of n for the trigonometric expression will be n = 2
What is trigonometry?The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.
The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.
Given that the ratio sin 30°: tan 45º can be written in form 1: n. The value of n will be calculated as:-
sin 30° = ½
tan 45° = 1
Then,
sin 30° : tan 45° = 1 : n
½ : 1 = 1 : n
n = 2

Original Price: $85, Sale Price: $51, Discount =
what is the discount? (tell me how you got your answer)
Answer:
the discount is 43.35 or the final price $7.65
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 51 × 85/100
Discount = 51 x 0.85
You save = $43.35
Final Price = Original Price - Discount
Final Price = 51 - 43.35
Final Price = $7.65

For an area of 18m²,the amount of a fertilizer required is 675g.
a) how much is needed to fertilise 11m²?
b) what area will 862.5g fertilise?
Answer:
a) 412.5g
b)23m²
Step-by-step explanation:
a)18m²=675g
11m²=x
by cross multiplication,
18x=11×675
18x=7425
x=7425/18
x=412.5g
b)18m²=675g
y=862.5g
18×862.5=675y
15525=675y
15525/675=y
y=23m²
Answer:
Step-by-step explanation:
This is a rate problem so using ratios is a good way to calculate the answer for different areas or amounts
675 g per 18 m² 675/18 g/m²
a) How many grams for 11m²
675/18 g/m² = ??? / 11 m² i cross multiply 675 times 11 divide by 18
or more simply multiply both side by 11
solving for the ???
(675)(11) g m² / 18 m² = ??? g = 412.5 grams ( the m²/m² cancel)
b) what area can be fertilised with 862.5 g? again applying ratio
this time we know the g and want to calculate an unknown area
675 / 18 = 862.5 / ??? this will take one more step since the ??? is
in the denominator
18 / 675 = ??? / 862.5 I just inverted both sides
18m² / 675g = ??? / 862.5g again simply multiply both sides by 862.5g
(18m²)(862.5g) / (675g) = ??? this time the grams cancel leaving m²
??? = 23 m²

Lateral surface area = 280 square inches
Step-by-step explanation:
Lateral surface area of a prism = (Perimeter of the base) × height of the prism
Perimeter of the base = 8 + 15 + 17
= 40"
Height of the prism = 7"
Therefore, Lateral surface area of the prism = 40 × 7
= 280 square inches

Answer:
1.The formula to convert Celsius to Fahrenheit is:
F = 1.8 C + 32
Multiply the Celsius temperature by 1.8.
Add 32 to this number.
Report the answer in degrees Fahrenheit.
Example: Convert 20°C to Fahrenheit.
F = 1.8 C + 32
F = 1.8 (20) + 32
1.8 x 20 = 36 so F = 36 + 32
36 + 32 = 68 so F = 68°F
20°C = 68°F

Triangles EFG and FGH are similar.
x/15 = 36/39
x/15 = 12/13
x = 15*12/13 = 180/13 ≈ 13.8 units
The required measure of x is given as 5.8 in the given triangle.
The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°.
What are similar triangles?Similar triangles are triangle that has a relationship as of some scale factor.
