Answer:

60

Step-by-step explaintion

5 x 12

Given:

The expanded form of [tex](x+s)(x-t)[/tex] is [tex]x^2+Kx-40[/tex].

Where, s, t, K are positive integers.

To find:

The smallest possible value of K.

Solution:

The expanded form of [tex](x+s)(x-t)[/tex] is [tex]x^2+Kx-40[/tex]. It means,

[tex](x+s)(x-t)=x^2+Kx-40[/tex]

[tex]x^2-tx+sx-st=x^2+Kx-40[/tex]

[tex]x^2+(s-t)x-st=x^2+Kx-40[/tex]

On comping both sides, we get

[tex]K=s-t[/tex]              ...(i)

K is a positive integer if s>t.

And

[tex]st=40[/tex]

The factor pairs of 40 are (1,40), (2,20), (4,10), (5,8), (8,5), (10,4), (20,2) and (40,1).

Since s>t, therefore the possible values for (s,t) are (8,5), (10,4), (20,2) and (40,1).

Using (i), find the value of K for each factor pair.

[tex]K=8-5=3[/tex]  

[tex]K=10-4=6[/tex]      

[tex]K=20-2=18[/tex]          

[tex]K=40-1=39[/tex]          

Therefore, the smallest possible value of K is 3.

Answer:

15

Step-by-step explanation:

3/5 = x/25

x = 15

Answer:

15

Step-by-step explanation:

25/5 = 5 so 3*5=15. also 3/5 is the same as 15/25. (15/5 = 3 and 25/5 = 5)

Answer:

(3 oz ; 4oz)

Step-by-step explanation:

Given that :

Mean = 3.5 oz

Standard deviation = 0.5 oz

According to the empirical rule ; 68% is 1 standard deviation from the mean.

Hence, the interval that would represent the middle 68% will be:

(3.5 oz - 0.5 oz) ; (3.5 oz + 0.5oz)

(3 oz ; 4oz)

Answer:

x≤0

JUst search it up on mathpapa lol

Answer:

x<0

Step-by-step explanation:

looks like this is an algebraic equation, we can get the answer by observation the "x" - witch we have to get, and see if x is bigger or smaller than the numbers. By doing that its not and we know x<0.

Step-by-step explanation:

From Trig

1 + tan²x = Sec²x

Also

Sec²x = 1/cos²x

Now

Cot²x = 1/tan²x = cos²x/sin²x

Putting all together

Cot²x(1+tan²x)

= Cot²x(sec²x)

= cos²x/sin²x(1/cos²x)

cos²x on the numerator and that one the denominator cancels out

we have

= 1/sin²x

From Trig

1/sin²x = cosec²x

So Our Answer = cosec²x.

Answer:

The value of sine of angle XYZ is equal to 0.96.

Step-by-step explanation:

Given that,

Base, b = 4 cm

Height, h = 13 cm

We need to find the sinY.

Using Pythagoras theorem,

YZ² = XY² + XZ²

YZ² = 4² + 13²

YZ = 13.60 cm

Using trigonometry,

[tex]\sin Y=\dfrac{13}{13.60}\\\\\sin Y=0.96[/tex]

So, the value of sine of angle XYZ is equal to 0.96.

Answer:

36

Step-by-step explanation:

All angles are right angles here. You know one is 54 so the other unknown side in that quadrant has to be 90 - 54.

As angle B is going to be the same as the angle that you just located in that quadrant, the answer is 36

Answer:

How to do it -

1 . Determine a single event with a single outcome.

2 . Identify the total number of outcomes that can occur.

3 . Divide the number of events by the number of possible outcomes.

Answer = 2/3

Answer:

7.64

Step-by-step explanation:

use tangent (opposite over adjacent)

tan27=x/15

multiply both sides by 15 to isolate the x

15tan27=x

use a calculator

answer = 7.64

Answer:

14 plantains

Step-by-step explanation:

Given

[tex]x \to[/tex] plantain in a pile

[tex]y \to[/tex] plantain received by each

[tex]n = 23[/tex] travelers

Required

The least value of y

Note that:

- There are x plantains in 1 pile, so there will be 63x in 63 piles

- The number of plantains shared is: 7 to 63x (7 represents the single plantain)

- 1 traveler gets y plantains, so 23y will receive 7 + 63x plantains

So, the equation is:

[tex]23y = 7 + 63x[/tex]

Make y the subject

[tex]y = \frac{7 + 63x}{23}[/tex]

The values of x and y must be integer and these values must be greater than 0.

Using trial by error method, we test the values of x starting from 1;

So, we have:

[tex]x = 1 \to y = \frac{7 + 63 * 1}{23} = \frac{70}{23} = 3.04[/tex]

[tex]x = 2 \to y = \frac{7 + 63 * 2}{23} = \frac{133}{23} = 5.78[/tex]

[tex]x = 3 \to y = \frac{7 + 63 * 3}{23} = \frac{133}{23} = 8.52[/tex]

[tex]x = 4 \to y = \frac{7 + 63 * 4}{23} = \frac{259}{23} = 11.26[/tex]

[tex]x = 5 \to y = \frac{7 + 63 * 5}{23} = \frac{322}{23} = 14[/tex]

So, the smallest values of x and y that satisfy the equation is:

[tex](x,y)=(5,14)[/tex]

Hence, the least number of plantain each traveler got is 14

Answer:

36

We determined above that the greatest perfect square from the list of all factors of 180 is 36.

Answer:

36

Step-by-step explanation:

You list all factors of 180 and then find a number that is a perfect square

1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, and 180.

As you can see, 36 is the greatest perfect square

The square root = 6

Answer:

3/5

Step-by-step explanation:

60% means 60 out of 100. For example if you get 60 marks in an exam of 100 marks. This means you got 60% marks.

Which is 60/100. This fraction can further be reduced to 6/10 [divide both numerator and denominator by 10)

6/10 = 3/5  [divide both numerator and denominator by 2)

So, the reduced form of 60% =3/5
