First start off with how many hours are in a day. (24 hours.)

Multiply 9 by 6, because there 6x4=24, and you would get 54 chapters a day. 

54x2=108 chapters in 2 days.

anygoal [31]

Answer:

c. 3680

Step-by-step explanation:

In 2010, the population was 8000.

In 2014, it increased by 15%.

Population in 2014 :

= 8000 + 15/100×8000

= 8000 + 1200

= 9200.

Now, 2/5 of the population was age 12 or under.

= 2/5 × 9200

= 2×1840

= 3680

Answer - c) 3680

Graph the line 6x-5y=30<br> . State the x- and y-intercepts.
Fudgin [204]

Answer:

x-intercept=(5,0) y-intercept =(0,-6)

Step-by-step explanation:

to find the x-intercept you substitute 0 in for y so the you're left with 6x=30 and you divide it by 6 on both sides leaving you with x=5

To find the y- intercept you set x=0 which leaves you with -5y=30 and you divide both sides by -5 and you're left with y=-6

Answer:

∴V=(14-2x)(10-2x)x

where V is the volume of the box in cubic units.

Step-by-step explanation:

Given that,

A rectangle has a length of 14 units and width of 10 units.

4 squares with dimensions x by x units are cut out from the each corner of the rectangle.

The length of the box is= (14-2x) units

The width of the box is =(10-2x) units

The height of the box is = x unit.

The volume of the box is = Length × width×height

                                          =(14-2x)(10-2x)x cubic units.
