Nikolay [14]

C. 52

Work:

(5x - 22) + (4x + 4) = 90

9x - 18 = 90

9x = 108

x = 12

4(12) + 4 =

48 + 4 = 52

If the first 4 terms of an infinite geometric sequence are 150, 120, 96, and 76.8, then the sum of all the terms in the sequence

hammer [34]

The sum of the sequence is 750

<h3>How to determine the sum of the series?</h3>

The series is given as:

150, 120, 96, and 76.8,

Start by calculating the common ratio using:

r = T2/T1

This gives

r = 120/150

r = 0.8

The sum of the series is then calculated as:

$S = \frac{a}{1 - r}$

This gives

$S = \frac{150}{1 - 0.8}$

Evaluate

S = 750

Hence, the sum of the sequence is 750

This drawing shows an Isosceles triangle. Work out the size of angle a.

antiseptic1488 [7]

50 degrees

All triangles have 180 degrees total.

Since it’s an isosceles triangle, the 2 bottom angles are congruent; thus, they have the same angle measurement.

Now just subtract the two angles from 180 to get the third angle.

180 - 65 - 65 = 50
