In an arithmetic series, the terms of the series are equally spread out. For example, in 1 + 5 + 9 + 13 + 17, consecutive terms

sertanlavr [38]

Sn = n/2(a + l); where sn is the sum of n terms, n is the number of terms, a is the first term and l is the last term.

1390 = n/2(3 + 136)
2780 = 139n
n = 2780/139 = 20

2nd term = 3 + 20 = 23
3rd term = 23 + 20 = 43

First three terms = 3, 23, 43

option b.

Find the values of the variables in the parallelogram. The diagram is not drawn to scale. Use theorems involving parallel lines

Ksju [112]

Answer:

Y=52(alternate interior angles)

X+y+z= x+52+72=180

= x+ 124=180

= x = 180-124=56

X=56

Z= 72 ( opposite angles of parallelogram)

Thus it is the last option

X=56 , y=52 , z = 72

Marcus and his family are planning a vacation that involves horseback riding. Horseshoe ranch charges a $12.95 ranch entrance fe

mart [117]

The equation that models the scenario is y = 12.95 + 14.95x

<h3>How to determine the linear equation?</h3>

The given parameters are:

Ranch charge = $12.95

Entrance fee = $14.95 per house

Represent the number of houses with x, and the total charge with y

So, we have:

y = Ranch charge + Entrance fee * x

This gives

y = 12.95 + 14.95x

Hence, the equation that models the scenario is y = 12.95 + 14.95x
