Answer:

77 is a composite number

Step-by-step explanation:

41 = 1 × 41

77 = 1 × 77 = 7 × 11

83 = 1 × 83

89 = 1 × 89

97 = 1 × 97

Answer:

Step-by-step explanation:I would say 77.The reason is because a composite number is where it has a multiple more than just itself or 1.So what you can do is write the multiples of each number.Then once you do that you can easily tell which numbers are composite and prime numbers.Remember prime numbers are numbers that just have a multiple of one and itself.

Hope this helps!!!!!

Suppose that a storm front is traveling at 33 mph. When the storm is 13 miles away a storm chasing van starts pursuing an averag

azamat

Answer:

It takes 0.619 hours (approximately 37 minutes) for the van to catch up with the storm.

They have driven 33.43 miles

They will catch up when their distances are equal.

Step-by-step explanation:

The speed of the van is 54 mph, and the speed of the storm is 33 mph. They are going in the same direction, so the relative speed is the difference of their speeds:

relative speed = 54 - 33 = 21 mph

Now, to find the time when the van reaches the storm, we just need to use the equation:

distance = speed * time

13 = 21 * t

t = 13 / 21 = 0.619 hours

The distance traveled by the van is:

distance = 54 * 0.619 = 33.43 miles

The van will catch up when the distances are equal (the distance of the storm is 13 + 33*0.619 = 33.43 miles)

2. A man drove 240 miles south at the rate of 60 miles per hour. On the return trip, he drove the rate of 40 miles per hour. The

shutvik [7]

$av = \frac{v_{2} - v_{1}}{t_{2} - t_{1}}$

$t_{1} = \frac{d}{v_{1}} = \frac{240}{60} = 4 \: hours \\ t_{2} = \frac{d}{v_{2}} = \frac{240}{40} = 6 \: hours$

$av = \frac{v_{2} - v_{1}}{t_{2} - t_{1}} = \frac{40 - 60}{6 - 4} = \frac{ - 20}{2} = - 10$

$av \: speed= 10 \\ av \: velocity = - 10 \: \: north$

Solve the given system by the substitution method <br>5x + y 19 <br>7x-2y = 13

lesya692 [45]

Answer:

x = 3 , y = 4

Step-by-step explanation:

5x + y = 19 --------- ( 1 )

=> y = 19 - 5x

7x - 2y = 13 ------------ ( 2 )

Substitute y in ( 2 ) :

7x - 2( 19 - 5x ) = 13

7x - 38 + 10x = 13

17x = 13 + 38

17x = 51

x = 3

Substitute x in ( 1 ) :

5x + y = 19

5( 3 ) + y = 19

15 + y = 19

y = 19 - 15

y = 4
