Answer:

second sum

Step-by-step explanation:

Note the given terms are perfect cubes, that is

343 = 7³

512 = 8³

729 = 9³

1000 = 10³

The sequence continues in this way as indicated by the dots ......

The first term is 343 and occurs when n = 7

The sequence is infinite, thus can be expressed as

∑ n³ from n = 7 to infinity

In the figure drawn below, two lines are intersecting each other. What is the measure, in degrees, of all the angles adjacent to

Roman55 [17]

Answer:

$\angle B =155^{\circ} , \angle D =25^{\circ} and \angle D=155^{\circ}$

Step-by-step explanation:

$\angle A = 25^{\circ}$

Vertically opposite angles : the angles opposite each other when two lines interest

So, ∠A is vertically opposite to ∠C

$\angle A = \angle C$ (Vertically opposite angles are equal)

So, $\angle C = 25^{\circ}$

$\angle A+\angle B = 180^{\circ}(\text{Linear pair})\\25^{\circ}+\angle B = 180^{\circ}\\\angle B = 180^{\circ}-25^{\circ}\\\angle B =155^{\circ}$

∠B is vertically opposite to ∠D

So, $\angle B = \angle D$ (Vertically opposite angles are equal)

So, $\angle D = 155^{\circ}$

Hence $\angle B =155^{\circ} , \angle D =25^{\circ} and \angle D=155^{\circ}$

-5x<-15x+40<br> Solve the following inequality for x

AveGali [126]

Answer:

x<4

Step-by-step explanation:

-5x<-15x+40

Add 15x to each side

-5x+15x<-15x+15x+40

10x<40

Divide by 10

10x/10<40/10

x <4
