Answer: 336 ways

Step-by-step explanation:

Given

Sam has 8 models and he needs to place 3 on a shelf

3 models can be selected out of 8 in [tex]^8C_3[/tex] ways

It can further be arranged among themselves in [tex]3![/tex] ways

Therefore, total number of ways are

[tex]\Rightarrow 3!\times ^8C_3\\\\\Rightarrow 3!\times \dfrac{8!}{3!5!}\\\\\Rightarrow 8\times 7\times 6=336\ \text{ways}[/tex]

Answer:

Step-by-step explanation:

Let the age of Kapil is 4x and that of Ramu is 5x.

After 5 years,

Kapil's age = 4x+5

Ramu's age = 5x+5

ATQ,

4x+5+5x+5 = 46

9x+10 = 46

9x = 36

x = 4

Present age of Kapil = 4x = 4(4) = 16 years

Present age of Ramu = 5x = 5(4) = 20 years

Answer:

1200

Step-by-step explanation:

72/4=$18 interest each year

amount x interest rate = interest

amount x .015 = 18

amount = 18/.015

amount = 1200

Answer:

288

Step-by-step explanation:

Answer:

-3√x

Step-by-step explanation:

(3-6) √x

= -3√x

Answer: 7.81

The formula is

y = 125* (1/2)^4

y = 125 / 16

y = 7.81

So at the end of the 4th week, the stock is worth only 7.81 dollars.

If that is not the motive and the first week doesn't count then the formula changes to...

y = 125 * (1/2)^(n-1)

y = 125 * (1/2)^3

y = 15.625 could be the other answer if you looked at it in that perspective

However, I would go with 7.81 as the answer.

Hope I helped :)

Answer:

Constant of proportionality = 30

Example: r = 6, V = 5

Step-by-step explanation:

Inverse proportion: V*r = constant

Given r=3, V=10, constant = V*r = 30

Example:

r = 6, V = 30/6 = 5

Answer: [tex]3^{\circ}C[/tex]

Step-by-step explanation:

Given

The temperature on Monday was [tex]-5^{\circ}C[/tex]

By Tuesday, it becomes [tex]-2^{\circ}C[/tex]

Change in temperature is the difference between the two temperatures.

[tex]\Rightarrow \Delta T=-2-(-5)\\\Rightarrow \Delta T=-2+5\\\Rightarrow \Delta T=3^{\circ}C[/tex]

Therefore, the change in temperature is [tex]3^{\circ}C[/tex].

Answer:x=1,-9

Step-by-step explanation:

Answer:

B - 12,111

C - 11,589

Step-by-step explanation:

Here are the options

A - 10, 999

B - 12,111

C - 11,589

In order to round off to the nearest thousand, look at the hundred figure, if the number is greater or equal to 5, add 1 to the thousand figure. If this is not the case, add zero. Replace all the figures before the thousand figure with zero. i.e. the hundred ten, unit

Rounding off 10,999 to the nearest thousand is 11,000

the hundred figure is greater than 5, so one is added to the thousand figure. The

Rounding off 12,111 to the nearest thousand is 12,000

the hundred figure is less than 5, so zero is added to the thousand figure.

Rounding off 11,589 to the nearest thousand is 12,000

the hundred figure is equal to 5, so one is added to the thousand figure.

Answer:

[tex]\sin(50^o) = \frac{3}{c}[/tex]

Step-by-step explanation:

Given

See attachment for triangle

Required

Expression to solve c

To solve for c, we simply calculate the sine of angle at B

i.e.

[tex]\sin(50^o) = \frac{Opposite}{Hypotenuse}[/tex]

This gives:

[tex]\sin(50^o) = \frac{3}{c}[/tex]

Make c the subject

[tex]c = \frac{3}{\sin(50^o)}[/tex]

Answer:

Each section of the board is 1/3 or 0.334(0.333333333333) of a meter

Step-by-step explanation:

3/5 divided by 3 is the equation we have to do.

3/5 divided by 3 is also equal to 3/5 times the reciprocal of 3 or 1/3

3/5 * 1/3

3*1 = 3

5*3 = 15

3/15 which can simplify to 1/3. (divide numerator and denominator by 3.)

Each section of the board is 1/3 or 0.334(0.333333333333) of a meter

Answer:

D

Step-by-step explanation:

Answer:

C) 3

Step-by-step explanation:

combine like terms

=> [tex]x^{2+3}[/tex] × [tex]y^{2+?}[/tex] = [tex]x^{5}y^{5}[/tex]

=> [tex]x^{5} y^{2+?}[/tex] = [tex]x^{5}y^{5}[/tex]

divide [tex]x^{5}[/tex] on both side to eliminate x

=> [tex]y^{2+?}[/tex] = [tex]y^{5}[/tex]

=> [tex]y^{2+3}[/tex] = [tex]y^{5}[/tex]

=> [tex]y^{5}[/tex] = [tex]y^{5}[/tex]

Answer:

cos(θ) = 3/5

Step-by-step explanation:

We can think of this situation as a triangle rectangle (you can see it in the image below).

Here, we have a triangle rectangle with an angle θ, such that the adjacent cathetus to θ is 3 units long, and the cathetus opposite to θ is 4 units long.

Here we want to find cos(θ).

You should remember:

cos(θ) = (adjacent cathetus)/(hypotenuse)

We already know that the adjacent cathetus is equal to 3.

And for the hypotenuse, we can use the Pythagorean's theorem, which says that the sum of the squares of the cathetus is equal to the square of the hypotenuse, this is:

3^2 + 4^2 = H^2

We can solve this for H, to get:

H = √( 3^2 + 4^2) = √(9 + 16) = √25 = 5

The hypotenuse is 5 units long.

Then we have:

cos(θ) = (adjacent cathetus)/(hypotenuse)

cos(θ) = 3/5

Answer:

x = 2 ± √11 (I believe)

Step-by-step explanation:

Problem 1

The two angles 6x and 30 are vertical angles, so they are congruent or the same in measure.

6x = 30

x = 30/6

x = 5 is the answer

====================================================

Problem 2

The two angles form a straight angle which is 180 degrees. We consider them a linear pair (since they are adjacent and supplementary).

So,

5x+(3x+12) = 180

8x+12 = 180

8x = 180-12

8x = 168

x = 168/8

x = 21 is the answer

Answer:

a = 360 * 0.27^n

Step-by-step explanation:

a = 360 * (1  - .073)^n

a = 360 * 0.27^n

Answer:

39 units

Step-by-step explanation:

area of polygon = area of rectangle VERD + area of triangle MVR

[length of rectangle (6) * width of rectangle (5)] + [1/2 * 3 (height of triangle) * 6 (height of triangle)] = area of polygon

(6*5) + (1/2*3*6) = area of polygon

30 + 9 = area of polygon

area of polygon = 39
