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

250 is the answers for the question

Step-by-step explanation:

please give me brainlest

Answer:

I got this it 250..........

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°

We have derived the definitions of the three basic trigonometric ratios sin, cos, and tan using similar right triangles.

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.

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

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:

Step-by-step explanation:

Answer:

The correct option is;

C. This advanced training seminar did not reduce response time, t(35) = -1.43, p > 0.05

Step-by-step explanation:

The given parameters are;

The population mean response time, μ = 9 minutes

The number of police officers in the sample, n = 36

The mean response time after the training, [tex]\overline x[/tex] = 8 minutes

The standard deviation of the response time after the training, s = 4.2 minutes

The level of significance, α = 0.05

The null hypothesis; μ ≥ 9

The alternative hypothesis; μ < 9

The test statistic for the t-test is [tex]t=\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}[/tex], therefore, we get;

[tex]t=\dfrac{8-9 }{\dfrac{4.2}{\sqrt{36}}} \approx -1.42857142857[/tex]

The degrees of freedom, df = n - 1 = 36 - 1 = 35

The critical-t at 0.05 level of significance is critical-t = 1.69, p(t < -1.43) > 0.05

and, we fail to reject the null hypothesis, therefore, the advanced training did not reduce the response time
