Answer:

c. 26 square centimeters

Step-by-step explanation:

The given figure's area can be calculated by subtracting the area of the small cut out with dimension 2 cm by 3 cm from the complete area of the shaded portion with dimensions 8 cm by 4 cm.

So, area of the shaded portion is :

$(8\times4)-(2\times3)$

= $32-6$

= 26 cm square.

Therefore, option C is the answer.

AveGali [126]

Answer:

64.3 miles ( D)

Step-by-step explanation:

Circular orbit height ( from the center of the earth ) = 100 mile

angle between satellite and earth = 50°

escape velocity = √2 * 17500 = 24748.73 miles /hour

distance between surface of earth and satellite

x = cos ∅

∴ Cos ∅ = x / 100

x = cos 50° * 100 ≈ 64.3 miles

slava [35]

In this question, we're assuming Ralph had 0 in his saving funds to start with.

The glasses cost 1200 dollars.

There are 12 months in a year.

Each month, Ralph is given his check two times, that means that Ralph receives his check 2(12), or 24, times per year.

Divide 1200 (the cost of the glasses) by 24 (the amount of times Ralph is given his check)

1200 / 24
Divide both numerator and denominator by 12
100 / 2
Simplify
50

Ralph should have put 50 dollars per pay check to pay for the glasses.

A is your answer.

Have an awesome day! :)
