Answer:

1.6

Step-by-step explanation:

To find the constant of proportionality, we do \frac{x}{y}. We see that 2/1.25=1.6, 4/2.5=1.6, 6/3.75=1.6, and 10/6.25=1.6. This means that the constant of proportionality is equal to 1.6.

Answer:

0.625

Step-by-step explanation:

To find the constant, you do y/x. For the first pair, if we divide 1.25/2, we get 0.625. We can do the same for all the pairs and get 0.625

Hope this helps :)

THE MEASURE OF TWO ADJACENT ANGLES OF THE PARALLELOGRAM ARE IN THE RATIO OF 3:2. FIND THE MEASURE OF EACH OF THE ANGLES OF THE P
BaLLatris [955]

Answer:

The adjacent angles are: 72 and 108

Step-by-step explanation:

Given

Angle Ratio = 3 : 2

Required

Find the measure of each angle

Let the angles be x\ and\ y.

Such that:

x + y = 180 --- adjacent angles of a parallelogram

and

x : y = 3 : 2 --- given

Convert to fraction

\frac{x}{y} = \frac{3}{2}

Cross Multiply:

2x = 3y

Make x the subject:

x = \frac{3}{2}y

x + y = 180 becomes

\frac{3}{2}y + y = 180

Take LCM

\frac{3y + 2y}{2}= 180

\frac{5y}{2}= 180

y = \frac{2}{5} * 180

y = 0.4 * 180

y = 72

Recall that:

x = \frac{3}{2}y

x = \frac{3}{2} * 72

x = 1.5 * 72

x = 108

<em>Hence, the adjacent angles are: 72 and 108</em>

You can helps me? <br>f(x) = x + 20 <br>g(x) = x + 5 <br>(f o g) (2) = ?​
pav-90 [236]
<h2>♪Answer : </h2>
  • f(x) = x + 20
  • g(x) = x + 5

»(f o g)(2)

  • find (f o g)(x)

»f(g(x))

»f(x + 5)

»x + 5 + 20

»x + 25

so, (f o g)(2) is

»2 + 25
