Answer:

106 m^2

Step-by-step explanation:

First multiply the shaded area:

12 * 10 = 120

Then multiply the white space:

7 * 2 = 14

Then subtract the white space from the shaded area to find the area of only the shaded area.

120 - 14 = 106

Final answer: 106 m^2

I hope this helps!

A tablet computer costs 189.69. it is marked up 30%. What is the final price of the tablet computer after its marked up.
saveliy_v [14]
The initial cost is 189.69. It is marked up 30%.

By simple calculations, 

Final cost of the tablet computer = Initial price + 30% of marked price

= 189.69 + (30/100 x 189.69)

This gives us the net value of 245.7. Hence the price of the computer after it's been marked up will be 245.7

Which of the following is equivalent to sec2θ−1sec2θ for all values of θ for which sec2θ−1sec2θ is defined?
galina1969 [7]

Answer:

2 sin^2 \theta

Step-by-step explanation:

According to the scenario, the following information is given:

= \frac{sec^2 \theta - 1 }{sec^2 \theta}

= (\frac{1}{\frac{cos^2\theta}{\frac{1}{cos^2\theta} }} - 1)

= 1 - cos^2\theta\\\\= 1 - (1 - 2 sin^2 \theta)\\\\= 2 sin^2 \theta

Therefore for the given equation, the answer is 2 sin^2 \theta

Please help with number 3!! I can’t figure it out.
FrozenT [24]

Answer:

Gabe worked 65, Abe worked 62 and Babe worked 69.

Step-by-step explanation:

Let Gabe = x

Therefore, Abe worked: x-3 and Babe worked x+4

So,

x+(x-3)+(x+4)=196

3*x+1=196

3*x=195

x=65

Then,

x-3= 62

x+4=69

HELP PLEASE ILL TRY TO MARK U BRAINLIEST
Anon25 [30]

Step-by-step explanation and answer:

For this you just need to plug in x for y = f(1/5x)

1/5(-4) = -4/5 or -0.8

1/5(-1) = -1/5 or -0.2

1/5(0) = 0

1/5(3) = 3/5 or 0.6

1/5(6) = 6/5 or 1.2 or 1 1/5
