A and B are two similar 2D shapes

Mathematics
1 answer:
Alexandra [31]3 years ago
7 0

Answer: 312.5\ cm^2

Step-by-step explanation:

Given

A and B are two similar shape with  lengths of 12 cm and 15 cm

A has an area of 200\ cm^2

For similar figures, ratio of the square of corresponding length is equal to the ratio of the area

\Rightarrow \dfrac{200}{A_b}=\dfrac{12^2}{15^2}\\\\\Rightarrow A_b=\dfrac{15^2}{12^2}\times 200\\\\\Rightarrow A_b=312.5\ cm^2

Suppose you have a bag of red, blue, and yellow marbles. If the probability of picking a red marble is1/6 and the probability of
yulyashka [42]
The probabilities of picking a red, blue, and yellow marble must be equal to 1. so

P(R)+P(Y)+P(B)=1

1/6+1/2+P(B)=1  making all terms have a common denominator of 6 we have:

1+3+6P(B)=6

4+6P(B)=6

6P(B)=2

P(B)=2/6

P(B)=1/3

In the figure below mPUR =77 and mST=74 Find mPR
eduard

Answer:

a)

<u>The angle formed by intersecting chords is half of the sum of the intercepted arcs:</u>

  • 1/2(mST + mPR) = m∠PUR
  • 1.2(74° + mPR) = 77°
  • 74° + mPR = 2*77°
  • mPR = 154° - 74°
  • mPR = 80°

b)

<u>The angle formed by two tangents is the half of the difference of the intercepted arcs:</u>

  • m∠PSR = 1/2(mPTR - mPR)
  • m∠PSR = 1/2(247° - (360° - 247°))
  • m∠PSR = 247° - 180°
  • m∠PSR = 67°

If f(x) = 2x – 3 and g(x) = 4x + 5, what is (f • g)(x)?
lorasvet [3.4K]

Answer:

Place the f(x) expression 2x-3 into the x in the g(x) expression 4x+5, so it will be 4(2x-3)+5; you can expand it out if you want

Consider the function f(x) = -2x+15 . What is the value of y when x = 3?
VashaNatasha [74]

Answer:

f(3) = 9

Step-by-step explanation:

Step 1: Define

f(x) = -2x + 15

x = 3

Step 2: Substitute and Evaluate

f(3) = -2(3) + 15

f(3) = -6 + 15

f(3) = 9
