Answer:

the selling price of the office equipment is R3040

Step-by-step explanation:

original price of the office equipment, C = R3800

discount for the selling price, d = 20% = 0.2

Discounted amount = 0.2 x R3800

                                 = R760

The selling price of the office equipment is calculated as follows;

The selling price = original price - discounted amount

The selling price = R3800 - R760

                             =  R3040

Therefore, the selling price of the office equipment is R3040

Answer:

7.5

Step-by-step explanation:

there is 1.5 cups of sugar for each cup of flour

1.5x5=7.5

Answer:

7.5 cups of sugar

Step-by-step explanation:

3/2 = 1.5 (this means there is 1.5 cups of sugar for every one cup of flour)

5 * 1.5 = 7.5

Answer:

C. Tan 40 = 60/x

Step-by-step explanation:

Reference angle = 40°

Opposite side to reference angle = 60

Adjacent side = x

Apply trigonometric function TOA,

Tan 40 = Opp/Adj

Tan 40 = 60/x

Answer:

32

Step-by-step explanation:

you have to find how many min in a hour so 20 divided by 5 is 4 then 4x8 is 32

Given:

The graph of two function f(x) and g(x).

To find:

The value of f(4) and the value of x if g(x)=2.

Solution:

In the given graph red curve is the graph of f(x) and the blue curve is the graph of g(x).

From the given graph it is clear that the value of the function f(x) at x=4 is -10. So,

[tex]f(4)=-10[/tex]

From the given graph, it is clear that the value of function g(x) is 2 at x=0. So,

[tex]g(x)=2,x=0[/tex]

Therefore, the value for the first blank is -10 and the value for the second blank is 0.

Answer:

One solution

Step-by-step explanation:

Let's solve your equation step-by-step.

p+9=2p−3

Step 1: Subtract 2p from both sides.

p+9−2p=2p−3−2p

−p+9=−3

Step 2: Subtract 9 from both sides.

−p+9−9=−3−9

−p=−12

Step 3: Divide both sides by -1.

−p

−1

=

−12

p=12

Answer:

p=12

Answer:

one solution

Step-by-step explanation:

2p-p=9+3

p=12

Answer:

Right angle

Step-by-step explanation:

Given

Right angle and Acute angle

Required

Which is greater

An acute angle has its angles less than 90 degrees while a right angle has its angle to be exactly 90 degrees

Take for instance:

[tex]Acute\ Angle = 80[/tex]

[tex]Right\ Angle = 90[/tex]

By comparison: 90 > 80

So, right angle is greater.

All the missing elements of the triangle by the Cosine rule are A = 40°, B = 45°, and C = 102°.

Given that,

Three sides on a triangle are,

a = 4

b = 5

c = 7

Used the formula of the Cosine rule which states that,

a² = b² + c² - 2bc cos A

b² = a² + c² - 2ac cos B

c² = a² + b² - 2ab cos C

Where, a, b, and c are three sides and A, B, and C are angles of a triangle.

Now, apply the Cosine rule to find the all angles of a given triangle,

a² = b² + c² - 2bc cos A

Substitute a = 4, b = 5 and c = 7,

4² = 5² + 7² - 2 × 5 × 7 cos A

16 = 25 + 49 - 70 cos A

70 cos A = 74 - 16

70 cos A = 58

Divide both sides by 58,

cos A = 58/70

cos A = 0.83

A = cos ⁻¹ (0.83)

A = 33.9°

Round to the whole number,

A = 40°

b² = a² + c² - 2ac cos B

Substitute a = 4, b = 5 and c = 7,

5² = 4² + 7² - 2 × 4 × 7 cos B

25 = 16 + 49 - 56 cos B

25 = 65 - 56 cos B

56 cos B = 65 - 25

56 cos B = 40

cos B = 40/56

cos B = 0.71

B = cos ⁻¹ (0.71)

B = 44.7°

Round to the whole number,

B = 45°

c² = a² + b² - 2ab cos C

Substitute a = 4, b = 5 and c = 7,

7² = 4² + 5² - 2 × 4 × 5 cos C

49 = 16 + 25 - 40 cos C

49 = 41 - 40 cos C

40 cos C = 41 - 49

40 cos C = - 8

cos C = - 8/40

cos C = - 1/5

cos C = - 0.2

C = cos ⁻¹ (0.2)

C = 101.5°

Round to the whole number,

C = 102°

Answer:

5 < x < 13

Step-by-step explanation:

9+4 > x

4 + x > 9

Answer:

13

Step-by-step explanation:

3y + 6 ÷ 2x = 3(4) + 6 ÷ 2(3) = 12 + (6 ÷ 6) = 12 + 1 = 13

Answer:

D. ∆ABC ~ ∆DEF

Step-by-step explanation:

The triangles given shows that the three corresponding angles of both triangles are congruent to each other. This means that they have the same shape but different size.

Triangles that are congruent to each other have the same shape and the same size while triangles that have the same shape but different size are similar to each other.

Therefore, ∆ABC is similar to ∆DEF (∆ABC ~ ∆DEF).

Answer: -4

Step-by-step explanation:

=-4

Answer:

66.3

Step-by-step explanation:

The tenths place is the first number to the right of the decimal

In this case, the 2

In order to round to this place, look at the number one place to its right. If the number is 4 or below, keep the same number 2. If the number is 5 or above, round the 2 to the next number, 3.

8 is above 5 so for this number, we will round the 2 to a 3
