Answer:

- 16

Step-by-step explanation:

following the rules as set out in PEMDAS

4² - 2(3 × 5 + 1) ← evaluate exponent term

= 16 - 2(3 × 5 + 1) ← evaluate multiplication inside parenthesis

= 16 - 2(15 + 1)

= 16 - 2(16) ← perform the multiplication

= 16 - 32 ← evaluate subtraction

= - 16

Can someone please help me?​

Answer:

15.5 seconds.

Step-by-step explanation:

From the time the driver activated the brakes until he stopped, he travelled 76 - 14 = 62 meters.

During this time the car slowed  down from 8 m/s to 0 m/s.

Assuming the deceleration was constant during this time we can apply one of the equations of motion for constant  acceleration:

s = (u + v)t / 2   where u = initial velocity, v = final velocity, s = distance and t = the time, so:-

62 = (8 + 0)t/ 2

62 = 8t/2

4t = 62

t = 15.5 seconds.

Michael has a fish tank that has a length of 7 inches,a width of 6 inches and a height of 8 inches. What is the total surface ar
White raven [17]

Answer:

292 inches^2

Step-by-step explanation:

So to start off this is a picture of the fish tank.

Next we will find the area of the bottom and top rectangles.

The side lenghts for those two is 7 and 8.

So the area of one is 56 and the area of 2 is 112 inches^2.

Now we will find the area of the left and right rectangles.

The side lenghts are 6 and 8.

So the area of 2 is 96 inches^2.

Now for the front and back rectangles.

The side lenghts for those two are 6 and 7.

So the area of both is 84 inches^2.

So after adding all the areas up the surface area is 292 inches^2.
