Dumisani earns R42480 per month. He splits his earnings in the ratio 7:5 and then saves the lesser amount. How much does he save?
Answer:
R17700
Step-by-step explanation:
Dumsani earns R42480 per month. He splits his earnings in the ratio 7:5 and then saves the lesser amount. How much does he save?
First step
We are given the ratio 7:5
The sum of the proportion = 7 + 5 = 12
We are told that he saves the lesser amount
The lesser ratio = 5
Therefore, the amount he saves is
= 5/12 × R42480
= 5 × 3540
= R17700
Therefore, he saves R17700

How do similar right triangles lead to the definitions of the trig ratios?
Answer:
The ratio of two sides of one right triangle is the same of the corresponding sides of any its similar triangles. ... Then a/b = A/B, which means that this ratio is a constant. The same for a/c = A/C, and b/c = B/C

We have derived the definitions of the three basic trigonometric ratios sin, cos, and tan using similar right triangles.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
Similar right triangles can be used to derive the definitions of trigonometric ratios, which are commonly abbreviated as sin, cos, and tan.
Consider a right triangle ABC, where angle A is the right angle.
Let's draw another right triangle ABD where angle A is also the right angle and angle B is congruent to angle D.
We say that triangles ABC and ABD are similar, which means that their corresponding angles are congruent and their corresponding sides are proportional.
Let's label the sides of triangle ABC as follows:
The side opposite angle A is side a (the hypotenuse).
The side opposite angle B is side b.
The side opposite angle C is side c.
We can label the sides of triangle ABD as follows:
The side opposite angle A is side a (the hypotenuse).
The side opposite angle B is side x.
The side opposite angle D is side y.
Since triangles ABC and ABD are similar, we can write the following proportion:
b / a = x / y
Solving for b, we get:
b = (x / y) * a
Now, we can use the Pythagorean theorem to relate the sides of triangle ABC:
a² = b² + c²
Substituting b with its value, we get:
a² = ((x / y) a)² + c²
Simplifying, we get:
a² = (x² / y²) a² + c²
Multiplying both sides by y², we get:
a² x y² = x² a² + c² y²
Now, we can solve for x/y, which is equal to sin(B) and y/a, which is equal to cos(B):
sin(B) = x / y = sqrt(a^2 - c^2) / a
cos(B) = y / a = c / a
Similarly, we can consider another triangle ABE, where angle A is the right angle and angle B is congruent to angle E.
We say that triangles ABC and ABE are also similar.
Let's label the sides of the triangle ABE as follows:
The side opposite angle A is side a (the hypotenuse).
The side opposite angle B is side x.
The side opposite angle E is side z.
Using the Pythagorean theorem for triangle ABC, we get:
a² = b² + c²
Substituting b with its value from triangle ABE, we get:
a² = ((z / x) a)² + c²
Simplifying, we get:
a² = (z² / x²) x a² + c²
Multiplying both sides by x², we get:
a² x² = z² a² + c² x²
Now, we can solve for z/x, which is equal to tan(B):
tan(B) = z / x = √(a² - c²) / c
Therefore,
We have derived the definitions of the three basic trigonometric ratios sin, cos, and tan using similar right triangles.

Where: A = P(1 + rt)
A = $1,265.00
I = A - P = $165.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year.
Solving our equation:
A = 1100(1 + (0.05 × 3)) = 1265
A = $1,265.00
The total amount accrued, principal plus interest, from simple interest on a principal of $1,100.00 at a rate of 5% per year for 3 years is $1,265.00.

Answer:
The answer is 116
Step-by-step explanation:
Because this shape is a quadrilateral, so the sum of the angles of a quadrilateral is a total of 360 degrees. So i added 90 + 90 + 64 = 244. And 360 - 244 = 116.
Answer:
116°
Step-by-step explanation:
There are 2 right angles so we add them:
1 right angle = 90°
2 right angle: 90° + 90° = 180°
As we can we have another value which is 64° so we add that as well:
180° + 64° = 244°
Since it is a 4-sided shape all the values will add up to 360°
Subtract 360 and 244
360° - 244° = 116°
x = 116°

What is the equation of the line that passes through the point (- 1, 5) and is parallel to the line y = - 3x + 5
Answer:
y - 5 = -3(x + 1)Step-by-step explanation:
Parallel lines has the same slope.
The equation of a line that passing through point (x₁, y₁) with a slope of m is:
y - y₁ = m(x - x₁)
m = -3
(-1, 5) ⇒ x₁ = -1, y₁ = 5
Therefore the equation:
y - 5 = -3(x + 1)

Melanie invested $8,600 in an account paying an interest rate of 2\tfrac{7}{8}2 8 7 % compounded monthly. Oliver invested $8,600 in an account paying an interest rate of 2\tfrac{3}{4}2 4 3 % compounded daily. After 10 years, how much more money would Melanie have in her account than Oliver, to the nearest dollar?
Answer:
$139
Step-by-step explanation:
The formula for compound interest =
A = P(1 + r/n)^nt
Where
P = Principal
r = Interest rate
n = Compounding frequency
t = time in years
A = Amount after t years
For Melanie
Melanie invested $8,600 in an account paying an interest rate of 2 7/8% compounded monthly.
Rate = 2 7/8% = 23/8% = 2.875%
Time = 10 years
n = monthly = 12
First, convert R percent to r a decimal
r = R/100
r = 2.875%/100
r = 0.02875 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 8,600.00(1 + 0.02875/12)^(12)(10
A = 8,600.00(1 + 0.002395833)^(120)
A = $11,460.64
For Oliver
Oliver invested $8,600 in an account paying an interest rate of 2 3/4 % compounded daily.
Rate = 2 3/4% = 11/4% = 2.75%
Time = 10 years
n = daily = 360 days
First, convert R percent to r a decimal
r = R/100
r = 1.375%/100
r = 0.01375 per year,
Then, solve our equation for A
First, convert R percent to r a decimal
r = R/100
r = 2.75%/100
r = 0.0275 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 8,600.00(1 + 0.0275/360)^(360)(10)
A = 8,600.00(1 + 7.6389E-5)^(3600)
A = $11,322.05
After 10 years, how much more money would Melanie have in her account than Oliver, to the nearest dollar?
This is calculated as
$11,460.64 - $11,322.05
=$ 138.59
Approximately to the nearest dollar = $139

The function C(x)=−15x+2304 represents the cost to produce x items. What is the least number of items that can be produced so that the average cost is no more than $33?
Answer:
152
Step-by-step explanation:
Given the function :
C(x)=−15x+2304
The least Number of items, x that can be produced so that average cost does not exceed $33
C(x) = less than or equal to 33
33 = - 15x + 2304
33 - 2304 = - 15x
-2271 = - 15x
x = 2271 / 15
x = 151. 4
Hence, the least number of items that can be produced is 152
