Answer:

x ≤ 4.9

Step-by-step explanation:

5x +1/2≤ 25

Multiply each side by 2 to get rid of the fractions

2(5x +1/2)≤ 25*2

10x +1 ≤ 50

Subtract 1 from each side

10x+1-1 ≤50-1

10x ≤ 49

Divide by 10 on each side

10x/10 ≤ 49/10

x ≤ 4.9

$$ PS = \frac{4}{3} x$

Solution:

Given PRQ is a triangle.

ST is a line parallel to RQ.

$$PT = x, \ PQ = 3x, \ SR=\frac{8}{3}x$

$TQ=PQ-PT$

$TQ=3x -x=2x$

<u>Triangle proportionality theorem,</u>

<em>If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally.</em>

$$\frac{PS}{SR} =\frac{PT}{TQ}$

$$\frac{PS}{\frac{8}{3} x} =\frac{x}{2x}$

Do cross multiplication, we get

$$ PS \times 2x=x \times \frac{8}{3} x$

Divide by 2x on both sides, we get

$$ PS = \frac{4}{3} x$

En una escuela hay 135 mujeres y la razón entre hombres y mujeres es de 7 a 9. ¿Cuántos estudiantes hay en la escuela? *

pochemuha

Answer:

There are 531.5625 students which is 531 students in the school

Step-by-step explanation:

We add the ratio numbers ( 7 + 9 = 16)

We then divide that number by 135 ( 135 / 16 = 8.4375)

After we multiply by each ratio number, ( 7 and 9).

And we end up with 531.5625, also 531 students.

--------------------------------------------------------------------------------

Hay 531.5625 estudiantes, que son 531 estudiantes en la escuela.

Explicación paso a paso:

Sumamos los números de razón (7 + 9 = 16)

Luego dividimos ese número por 135 (135/16 = 8.4375)

Después, multiplicamos por cada número de razón (7 y 9).

Y terminamos con 531.5625, también 531 estudiantes.

The annual interest rate on a $10,000 loan is 18%. The exponential function that represents this is y = 10000(1.18t). Write the

Yuki888 [10]

Answer:

$y=10000(1.015)^{12t}$

option-B......Answer

Step-by-step explanation:

We are given

amount taken for loan =$10000

so, P=10000

annual interest rate =18%

r=0.18

now, we can use formula

$y=P(1+\frac{r}{n} )^{nt}$

Since, it is compounded monthly

so, n=12

we can plug values

$y=10000(1+\frac{0.18}{12} )^{12t}$

$y=10000(1.015)^{12t}$
