turn each number into an improper fraction

27 1/2 = (2*27+1 )/2  = 55/2

2 1/4 = (4*2+1)/4  = 9/4

55/2 divided by 9/4

copy dot flip

55/2 * 4/9

220/18

110/9                                       12*9 = 108

12    2/9  weeks

or if we round   13 weeks

If △STU is similar to △XYZ, the sides of △STU must be congruent to thecorresponding sides of △XYZ.A. TrueB. False
katovenus [111]

Similar triangles are triangles that have the same interior angles and the corresponding sides are proportional, that is, for triangles STU and XYZ we have the proportion:

\frac{ST}{XY}=\frac{TU}{YZ}=\frac{SU}{XZ}

The corresponding sides are congruent only if the proportion rate is 1, but that is not always true and it's not necessary.

Therefore the correct option is B: False

If the corresponding sides are congruent, the triangles are congruent.

Ned took a test with 25 questions. He lost 4 points for each of the 6 questions he got wrong and earned an additional 10 points
vladimir2022 [97]

Answer: Ned received 86 Points overall on the test and Ned lost 24 points overall on his test.

Step-by-step explanation: Ned got 19 questions correct and 6 questions incorrect. He as well got 10 bonus points for answering a bonus question correctly. We know each of the questions on the test (excluding the bonus question) is worth 4 points.

If Ned got 19 questions correct that means 19 x 4 = he received 76 points.

If Ned got 6 questions incorrect that means 6 x 4 = he lost 24 points.

If Ned got 1 question correct that is worth 10 points, that means he got an additional 10 points to his score.

We can add the amount of points Ned scored to the amount of bonus points he earned; 76 + 10 = 86 points total on his test.

G(3)=g, left parenthesis, 3, right parenthesis, equals
Dovator [93]

The inverse function will be g(x) = (x + 3) / 5. Then the value of the function f(5) and g(3) will be 22 and 6/5.

<h3>What is inverse of a function?</h3>

Let the function will be

f: X → Y

Then the inverse function will be

f⁻¹: Y → X

The function is given below.

f(x) = 5x – 3

Then the value of the function f(x) at x = 5, will be

f(5) = 5 × 5 – 3

f(5) = 22

The g(x) is the inverse function of f(x).

Then the function g(x) will be

5g(x) – 3 = x

        g(x) = (x + 3) / 5

Then the value of function g(x) at x = 3, will be

g(3) = (3 + 3) / 5

g(3) = 6 / 5

The complete question is given below.

The function f(x) = 5x – 3. And the function g(x) is the inverse of f(x). Find the value of the function f(5) and g(3).
