Answer:

Step-by-step explanation:

The opposite faces are congruent, that is the surface area (SA) is

SA = top/ bottom + 2 sides + front/ back

= (3 × 2) + (3 × 2) + (2 × 5) + (2 × 5)+ (3 × 5) + (3 × 5)

= 6 + 6 + 10 + 10 + 15 + 15

James is painting a wooden slat fence he had installed around his backyard. The fence has a total of 180 wooden slats. Suppose J

Olenka [21]

Answer:

1 slat every 2 minutes.

Step-by-step explanation:

James is able to paint 2 slats every 5 minutes.

James and Gabe together are able to paint the whole fence (180 slats) in 3 hours and 20 minutes (200 minutes)

The rate of 180 slats in 200 minutes is equal to 18 slats in 20 minutes, and is equal to 9 slats in 10 minutes.

The rate of James is 2 slats in 5 minutes, which is equal to 4 slats in 10 minutes.

Subtracting the rate of James and Gabe together (9 slats in 10 minutes) by the rate of James alone (4 slats in 10 minutes), we have the rate of Gabe, which is 5 slats in 10 minutes, or 1 slat in 2 minutes.

1) Billy walks 15 miles every day to soccer practice, and catches a ride home from his grandma. Billy had 5 practices last week.

nignag [31]

1 ) Billy walks 15 miles every day to soccer practice and he had 5 practices last week.

We know that, 1 mile = 1760 yards

So, 15 miles = (15× 1760) yards = 26400 yards

Thus the total distance walked in 5 practices will be: $(26400*5)yards = 132000 yards$

2) Mark's current age is $t$ years

So, his age was in 10 years ago $=(t-10)years$

Given that, his current age is 3 times his age 10 years ago.

So, the equation to represent this situation will be : $t= 3(t-10)$

Tony's dorm is 7.5 miles far from the library.

Step-by-step explanation:

Given points are;

(4,0) and (12,6)

$x_1=4,\ \ \ \ \ \ \ y_1=0\\x_2=12,\ \ \ \ \ \ y_2=6$

Using point distance formula;

Distance = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$Distance=\sqrt{(12-4)^2+(6-0)^2} \\Distance=\sqrt{(8)^2+(6)^2}\\Distance=\sqrt{64+36}\\Distance=\sqrt{100}\\Distance=10\ units$

One unit represents 0.75 miles, therefore,

10 units = 0.75*10 = 7.5 miles

Tony's dorm is 7.5 miles far from the library.
