Answer:

Step-by-step explanation:

product of two consecutive numbers is always even.

n(n+1)

case 1

if n is odd,let n=2k+1,where k is an integer

n+1=2k+1+1=2k+2=2(k+1)

n(n+1)=(2k+1)[2(k+1)]=2(2k+1)(k+1)=even number.

case 2

if n is even,let n=2m,where m is an integer.

n+1=2m+1

n(n+1)=2m(2m+1)=even integer.

so in both cases n(n+1) is even.

Answer:

total time = 250/x

Step-by-step explanation:

Jose drove 300 miles on his vacation. He drove an average of 1.5 times faster on the second half of the trip. The time he spent driving can be calculated as follows.

The first half of the trip

distance = 150 miles

time = ?

speed = x

speed = distance/time

time = distance/speed

time = 150/x

The second half of the trip

distance = 150 miles

time = ?

speed = 1.5x

time = distance/speed

time = 150/1.5x

Total time travelled = 150/x + 150/1.5x

total time = 150/x + 100/x =150 + 100 /x = 250/x

total time = 250/x

Step-by-step explanation:

Counterclockwise is going left, so if you start at the top, 270 degrees left of a clock will result in the same as 90 degrees clockwise.

Answer:

Yes it will.

Step-by-step explanation:

Imagine a circle. A full rotation is 360 degrees. So, that means you're going to be 90 degrees froma full rotation. That means that if you back track 90 degrees you're going to get to the same spot as when you go clockwise 270 degrees. The best way to think of it is having the hands of a clock start at 12.

Answer:

-7/6

Step-by-step explanation:

You first have to find the common denominator, which in this case is 12. 3/4ths can be converted to 9/12ths. Then you subtract 9/12ths from -5/12, and get -14/12. Finally you simplify it and get -7/6.:)

Answer:2

Step-by-step explanation:

Answer:

The answer is 386 feet.

Step-by-step explanation:

This equation simply asks to plug in a value that gives you the final value of the height. 450 is the initial height, and r (or l) is referred to as the amount of seconds after the item is dropped. 16 is the constant value of feet that the ball drops within one second.

Therefore, by substituting 4 for r (or l) and multiplying it by 16, you will receive 64 feet in 4 seconds. Finally, you need to subtract this from 450 feet, giving you a final answer of 386 feet.

-11 and -11 are the two numbers that adds to -22 and multiply to 121

If we add 11 and 11 then it equals to -22.

if we multiply 11 and 11 then,it equals to 121

hope it helps...

Good luck on your assignment

Answer: Both numbers are -11.

Step-by-step explanation:

You can represent this using two equations, where the variables are x and y:

[tex]x + y = -22\\x * y = 121[/tex]

Then, solve the system using substitution by substituting y in the first equation into the second equation:

[tex]y = -22 - x\\ x * (-22 - x) = 121\\\\-x^2 - 22x - 121 = 0\\x^2 + 22x + 121 = 0\\[/tex]

Then, solve the quadratic equation by factoring it:

[tex](x+11)^2 = 0[/tex]

The only solution (or zero) to the equation is -11.

This means that both numbers are equal to -11.

-11 - 11 = -22

-11 * -11 = 121

Answer:

a) 34m/s

b) 42.5 m/5

Step-by-step explanation:

The average speed is the distance divided by the time. This is:

Vaverage = 1700m/50s=34 m/s

The value of K is, knowing that the area under the curve is 1700

k*30+k*20/2=1700

30k + 10k = 1700

40k=1700

k=42.5

Step-by-step explanation:

Question:

Yuet solved the equation [tex]6a - 2b = 12[/tex] for a.

Her steps are shown below.

1. Subtract 2b: [tex]6a = 12 - 2b[/tex]

2. Divide by 6: [tex]a = 2 - \frac{b}{3}[/tex]

Answer:

In step 1 she needed to add 2b to both sides of the equation.

Step-by-step explanation:

Given:

The above steps shows how Yuet solved an equation

Required:

True statement about Yuet's work

The implication of the statement is to state what Yuet should have done instead of what she did.

In step 1, she subtracted 2b from both sides of the equation; this is wrong.

Instead of subtracting, she ought to add 2b to both sides of the equation.

The correct steps and result is as follows:

1. Add 2b: [tex]6a = 12 + 2b[/tex]

2. Divide by 6: [tex]a = 2 + \frac{b}{3}[/tex]

Hence, we can conclude that in step 1 she needed to add 2b to both sides of the equation.

Answer:

A:In step 1 she needed to add 2b to both sides of the equation.

Answer:

flour = 11.5, sugar has to be equal to 2.75 pounds.

Step-by-step explanation:

your 2 inequalities are:

2x + 3y <= 40

y <= 2x + 6

the second equation can be shown as:

-2x + y <= 6

solve the equality portion of these 2 inequalities.

those are the following equations:

2x + 3y = 40

-2x + y = 6

add these equations together and solve for y to get

y = 11.5

that appears to be a break even point.

when y = 11.5, the first inequality is solved as follows:

2x + 3y <= 40

replace y with 11.5 and the inequality becomes:

2x + 34.5 <= 40

solve for x to get

x <= 2.75

when y = 11.5, the second inequality is solved as follows:

-2x + y <= 6

replace y with 11.5 and the inequality becomes:

-2x + 11.5 <= 6

solve for x to get x >= 2.75

this indicates that, when y = 11.5, x has to be equal to 2.75.

both constraints are satisfied.

Answer:

Let each sack of sugar weigh $s$ pounds and each sack of flour weigh $f$ pounds. Then from the given information, $2s + 3f \le 40$ and $f \le 2s + 6.$ Also, $s > 0$ and $f > 0.$ We graph these the intersection of these inequalities below.(document attached

We see that the largest possible value of $f$ occurs at the points where the lines $2s + 3f = 40$ and $f = 2s + 6$ intersect. Solving for $f,$ we find $f = \boxed{\frac{23}{2}}.$

Answer:

The first possible answer, -27a³b^6 + 8a^9b^12, is the sum of cubes.

Step-by-step explanation:

The middle two possible answers involve " a " with no exponent, so these could not be correct.

Looking at the first and fourth possible answers, we see that the first term of -27a3b6+8a9b12 is a perfect cube; it could be re-written as (-3ab²)³.  The second term could be rewritten as (2a³b^4)³.  So the first possible ansswer is the SUM of CUBES.

Answer:

Week 1: 80

Week 2: 160

Week 3: 320

Week 4: 640

Week 5: 1280

Step-by-step explanation:

Week 5 there are 1280 infected trees, the infection numbers double weekly. Divide week 5 (1280) by 2 and you find week 4 (640) divide that by 2 and you find week 3 (320) divide that by 2 and you find week 2 (160) divide that by 2 and you find the first week (80)

The Number of infected trees are:

Week 1: 80

Week 2: 160

Week 3: 320

Week 4: 640

Week 5: 1280

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

In week 5, 1280 trees were infected.

As, Each week, the number of trees infected with the fungus doubles.

In week 4:

Number of trees infected = 1280 / 2 = 640

In week 3:

Number of trees infected = 640/ 2 = 320

In week 2:

Number of trees infected = 320 / 2 = 160

In week 1:

Number of trees infected = 160/ 2 = 80

Answer:

x = 6

Step-by-step explanation:

(3x-2)/4  +1 =5

subtract 1 from each side

(3x-2)/4  +1 -1 =5-1

(3x-2)/4   =4

Multiply each side by 4

(3x-2)/4  *4 = 4*4

3x-2 = 16

Add 2 to each side

3x-2+2 = 16+2

3x = 18

Divide each side by 3

3x/3= 18/3

x = 6

Answer:

[tex]x = 6[/tex]

Step-by-step explanation:

Answer:

The answer is option 2.

Step-by-step explanation:

In the question, the independent variable is time and dependent is distance. As the time changes, the distance will also change it means the distance depends on time.

For example,

[tex]d = 0.5 + 5t[/tex]

Let t = 1,

[tex]d = 0.5 + 5(1)[/tex]

[tex]d = 5.5 \: miles[/tex]

Let t = 5,

[tex]d = 0.5 + 5(5)[/tex]

[tex]d = 25.5 \: miles[/tex]
