The equation used for solving this problem is length times width times height and multiply everything by 2 since there is 2 sides to the shape. The equation for the blue figure would be 2x(12x10+12x2+10x2). When this is solved, you get 328 centimeters squared. Now on to the pink figure. The equation for the pink figure would be 2x(8x6+8x3+6x3). When this is solved, you get 180 centimeters squared. Lastly, you add your two products together (328+180) to get 508 centimeters squared.

Alison walks 2/5 mile from her house to the mailbox. Then she walks 1/3 mile to the bus stop. What is the total distance Alison

stealth61 [152]

Answer:

Total distance:

d=11/15 miles or 0.73 miles

Step-by-step explanation:

Alison walks 2/5 miles from her house to the mailbox.

Then she walks 1/3 mile to the bus stop.

Thus, the total distance can be calculated by adding the miles

i.e.

$d=\:\frac{2}{5}+\frac{1}{3}$

LCM of 5,3 is 15

$=\frac{6}{15}+\frac{5}{15}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}$

$=\frac{6+5}{15}$

$=\frac{11}{15}$

$=\:0.73$ miles

Thus,

Total distance:

d=11/15 miles or 0.73 miles

Which point lies on the circle represented by the equation (x+5) + (y-9) = 8

olga_2 [115]

Answer:

(-5,9+√8)

Step-by-step explanation:

There are two ways in which you can find a point that lies in the circle. One of them is to do y the subject of the formula, and another one is to determine the center of the circumference, and with the information of the radius, you can sum this value upward or downward.

the general equation of a circle is:

$(x-h)^2+(y-k)^2=r^2$
