A typewriter costing $75.00 marked up 40% on cost M = 40 and S = 105
Kipish [7]3 years ago
4 0

Answer:

M = 30 and S = 105.00

Step-by-step explanation:

The cost of a typewriter  = $75.00

Marked up on cost (M)= 40%

We will find out marked up (M) = \frac{40}{100} × 75

= 0.40 × 75

M = 30

Now we will find out Selling price by adding cost of typewriter and marked up cost.

75.00 + 30 = 105

S = $105.00

Therefore,

M =  30 and S = 105.00

Find x.
Vadim26 [7]

The value of x is 28 millimeters in the composite figure of two right-angled triangles lying next to each other

<h3>What is a composite figure?</h3>

A composite figure is a figure that is produced from the combination of two geometric shapes together.

The diagrammatic expression of a composite figure consists of two right-angled triangles lying next to each other can be seen in the image attached below.

For the left-side right-angled triangle, we have:

13² = h² + 5²

h² = 13² - 5²

h = √(169-25)

h = 12

Recall from the diagram that:

h² = pq

  • If p = 5 and q = x

∴

12² = 5x

x = 144/5

x ≅ 28 millimeters

I took notes and went back through the lesson but I can't get it. Help, please!!!
aliina [53]

Answer:

\/

Step-by-step explanation:

▪Picture 1. x = 28

\frac{x}{42}  =  \frac{10 + x}{57} \\ 42(10 + x) = 57x \\ 420 + 42x = 57x \\  \frac{  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: - 42x =  - 42x}{ \frac{420}{15}  =  \frac{15x}{15} }   \\  \\ 28 = x
