Distance between Luke's house and restaurant is 16 m.

Since he drives to the restaurant and back to home, so total distance travelled will be double of 16 m that is 32m.

Speed at which Luke drove is 0.8 miles/minute.

Speed, distance and time can be related by the formula :

speed = \frac{distance}{time}

So in order to find time,

time = \frac{distance}{speed}

time = \frac{32}{0.8}

time = 40 minutes.

Answer: The number of minutes since Luke started driving from his house to his distance from the house is 40 minutes.

The total distance traveled from his house to the restaurant and then back to his house =16+16= 32 miles.

He drove at the constant speed of 0.8 miles per minute.

Total Time taken = \frac{Distance travled}{Speed}\

==\frac{32}{0.8} =\frac{320}{8} =40 minutes.

In a triangle, the measure of the first angle is 24 degrees more than the measure of the second angle. The measure of the third
insens350 [35]

Answer:

104°

Step-by-step explanation:

let the second angle be x , then

the first angle is x + 24

the third angle is 4x , thus summing and equating to 180

x + x + 24 + 4x = 180, that is

6x + 24 = 180 ( subtract 24 from both sides )

6x = 156 ( divide both sides by 6 )

x = 26

Thus largest angle = 4x = 4 × 26 = 104°

The formula for perimeter of a rectangle is given by p = 2l + 2w, where p = perimeter, l = length, and w = width. solve the form
TiliK225 [7]
Perimeter formula
p = 2l + 2w

I reverse left-right side
2l + 2w = p

Move 2l to the right
2l + 2w = p
2w = p - 2l

Move 2 to the right
2w = p - 2l
w = (p - 2l)/2

Summary
p = 2l + 2w
2l + 2w = p
2w = p - 2l
w = (p-2l)/2

Sladkaya [172]
<span>1). 16 x 3/4 Step One- 16/1 x 3/4 Step two- 4 goes into 16 four times so cancel the 4 and change the 16 to a 4... Step three- 4 x 3=12 2). (81/16) divided by (9/14) Step one- Since its division we use (FREEZE CLAP FLIP)= Freeze (81/16) Clap the division sign and change it to a multiply sign and Flip the riprocals (9/14) The equation is now 81/16 X 14/9 Next 81 is divisible by 9 and 16 and 14 are divisible by 2 So the new formula i s 9/8 X 7/1 Solution=63/8 3). 2/3 divided by 4/3 Flip the reciprocals for the 4/3 New equation is 2/3 X 3/4 2 and 4 are divisible by 2 and the 3's cancel each other out Solution: 1/2</span>
