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:

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:

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:

95°

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

Hi there!  

»»————-　★　————-««

I believe your answer is:  

Option A;  [tex]m \leq\frac{3}{5}[/tex]

»»————-　★　————-««  

Here’s why:  

⸻⸻⸻⸻

[tex]\boxed{\text{Solving for 'm':}}\\\\5m+1\leq4\\--------\\\rightarrow 5m + 1 - 1 \leq 4 - 1\\\\\rightarrow 5m\leq3\\\\\rightarrow \frac{5m\leq3}{5}\\\\\rightarrow \boxed{m\leq\frac{3}{5}}[/tex]

⸻⸻⸻⸻

Any number that is less than or equal to the value of three-fifths would work.

The option that is less than or equal to (3/5) is option A.

Assuming that there are more options than the options shown, choose the numbers that are less than or equal to (3/5).

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:

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:

y = 38

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Consider the angles in the large outer triangle, then

x + 46 + 78 = 180

x + 124 = 180 ( subtract 124 from both sides )

x = 56

Consider the 3 angles in the smaller inner triangle, then

y + x + 86 = 180 , that is

y + 56 + 86 = 180

y + 142 = 180 ( subtract 142 from both sides )

y = 38

Answer:

Step-by-step explanation:

The tangent to the angle makes an angle of 90° with the radius.

The interior angle of the equilateral triangle is 60, so that leaves 90-60 = 30° for the remaining angle with the tangent.

By the exterior angle theorem, 30°+x° = 60° (interior angle of the equilateral triangle), therefore

x = 60-30 = 30°.

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:

P(2): 1/5

P(4): 1/5

P(odd number): 3/5

P(whole number): 5/5

P(6): 0/5

P(2 or 3): 2/5

Step-by-step explanation:

There are 5 equal sections in this circle. So, the probability to land in each section is 1/5.

The odd numbers are 1, 3, and 5. Since each section is 1/5, you add

1/5 + 1/5 + 1/5 = 3/5. That is the probability that you will land in any odd number.

Because all the numbers listed are whole numbers, no matter where the spinner lands it will be a whole number. So, the probability is 5/5 for whole numbers.

Since 6 is not a section, it's probability will be 0/5 (or you can just put 0).

"Or" means you add the two probabilities. Add the probability of landing on 3 (which is 1/5) to the probability of landing on 2 (which is also 1/5). So, you get 2/5.

Answer:

C. The perimeter of ΔABC is 7.6 units.

Step-by-step explanation:

Triangle ABC is given by the points A(3, 2), B(4, 4), and C(5, 1). Determine if each statement is True or False.

A. The perimeter of ΔABC is 9.9 units.

B. ΔABC is an equilateral triangle.  

C. The perimeter of ΔABC is 7.6 units.

Solution:

A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, equilateral, scalene, acute, obtuse and right angled triangle.

The distance between two points (x₁, y₁) and (x₂, y₂) in the coordinate plane is:

[tex]Distance=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]

Given the vertices of triangle ABC as A(3, 2), B(4, 4), and C(5, 1). Therefore we have to calculate the side lengths of the triangle:

[tex]AB=\sqrt{(4-3)^2+(4-2)^2}=\sqrt{1+4}=\sqrt{5} \\\\AC=\sqrt{(5-3)^2+*(1-2)^2}=\sqrt{4+1}=\sqrt{5} \\\\BC=\sqrt{(5-4)^2+(1-4)^2}=\sqrt{1+9}=\sqrt{10}[/tex]

1) Perimeter of the triangle = AB + AC + BC = √5 + √5 + √10 = 7.6 units

2) Since only two sides of the triangle are equal (i.e. AB = AC), hence the triangle is an isosceles triangle.

Answer:

Step-by-step explanation:

The total amount of students is 240

240(50%) = 120 > 60 so, the first true or false is False

240(5%) = 12 = 12 so, the the second true or false is True

240(60%) = 144 = 144 so, the third true or false is True

132 + 12 = 144

Answer:

288

Step-by-step explanation:

48÷2=24(9+3=12) =24×12=288

Answer:

there is no number that matches the notation

Look at the picture for the answer.

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:

30 balloons

Step-by-step explanation:
