Answer: 10/30

Step-by-step explanation:

There are 30 cards and 10 - 10= 0. So it’ll just be 10/30

The magnitude of the force of 34.64 is more than the magnitude of the force of 24.75. The direction of the force is on the 34.64 sides.

The product of mass and its acceleration is known as force.

Two students are pulling an object with ropes. one student pulls with a force of 40 pounds at an angle of 30° above the ground, and the other student pulls with a force of 35 pounds at an angle of 45° above the ground.

Then the direction of the force will be

→ 40 × cos 30° = 34.64

→ 35 × cos 45° = 24.75

Then

34.64 - 24.75 = 9.89

Then the direction of the force is on the side of 40 pounds.

Answer:

[tex] x = \dfrac{-1 \pm \sqrt{11}}{2} [/tex]

Step-by-step explanation:

(2x - 3)² - 14 = 2x(x - 7)

4x² - 12x + 9 - 14 = 2x² - 14x

2x² + 2x - 5 = 0

[tex] x = \dfrac{-2 \pm \sqrt{2^2 - 4(2)(-5)}}{2(2)} [/tex]

[tex] x = \dfrac{-2 \pm \sqrt{4 + 40}}{4} [/tex]

[tex] x = \dfrac{-2 \pm 2\sqrt{11}}{4} [/tex]

Hi maryanne!

Answer:

C. e<4

Step-by-step explanation:

Since [tex]\frac{e}{220} \leq 0.02[/tex]

         e [tex]\leq[/tex] 0.02 x 220

         e [tex]\leq[/tex] 4.4 (multiply 220 both sides)

         e [tex]\leq[/tex] 4.4

The side lengths of the two cubes are 6 meters and 12 meters respectively.

Mathematically, the volume of a cube is calculated by using this following formula:

Volume = m³

Where:

m is the side lengths of a cube.

Translating the word problem into an algebraic expression, we have;

m³ + (2m)³ = 1944

m³ + 8m³ = 1944

9m³ = 1944

m³ = 1944/9

m = ∛216

m = 6 meters.

For the bigger cube:

2m = 2 × 6

2m = 12 meters.

The sequence an=an−1+2 is an arithmetic sequence

The first three terms in the sequence are (a) 8, 10, 12

The sequence is given as:

an=an−1+2

Where:

a1 =8

Start by calculating a2 using:

a2=a1+2

This gives

a2=8+2 = 10

Calculate a3 using:

a3=a2+2

This gives

a3=10+2 = 12

So, we have:

a1 = 8, a2 = 10 and a3 = 12

Hence, the first three terms in the sequence are (a) 8, 10, 12

The perimeter is the sum of all sides. Then the perimeter of the kite is 27 units, then the correct option is C.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The length of the kite (x) will be given by the Pythagoras theorem

H² = P² + B²

H² = 15² + 8²

H² = 225 + 64

H² = 289

 H = 17

Then

[tex]\rm x = \dfrac{H}{2} \\\\x = \dfrac{17}{2}\\\\x = 8.5[/tex]

And another length of the kite is 5 units.

Then the perimeter of the kite will be

Perimeter = 2(8.5 + 5)

Perimeter = 27

Answer:

C: 8, 15, 17

Step-by-step explanation:

The easiest way to do this is simply to memorize the first few Pythagorean triples. It saves time. But it can also be hard to remember that. To see if something is a triple...

1. [tex]a^{2} + b^2=c^2[/tex]. This means square the first one, the second and add. Then square the last one. The sum of the first two with the last one should be the same.

2. For this to work, they have to be in order from least to greatest. All of these are.

3. Let's fill in the equation:

8^2= 64.

15^2= 225.

225+64= 289

17^2= 289.

It matches! It's a triple.

The  value of x will make the triangles similar by the sss similarity theorem is 77

A triangle is a 2-dimensional shape with 3 sides and angles

From the given diagram, we will take the ratio of simlar sides to determine the value of "x"

35/x = 20/44

Cross multiply

20x = 35 * 44
20x = 1540
x = 154/2
x = 77

Hence the  value of x will make the triangles similar by the sss similarity theorem is 77

The expression for the angular acceleration of the sphere will be 20Tr/13MR².

It should be noted that angular acceleration simply means the time rate of change of the angular velocity.

From the information given, I = (2/5(MR² + M(R/2)² = MR²(2/5 + 1/4) = 13MR²/20

The torque (Q) will be Tr. Therefore, the expression for the angular acceleration of the sphere will be:

= Q/I

= Tr/13MR²/20

= 20Tr/13MR²

The constant term in the function f(x) = x² + 8x + 15 would be 15.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

A function f(x) has x-intercepts of –3 and –5 means

f(x) = (x+3)(x+5)

f(x) = a(x + 3)(x + 5), here a is a multiplier

let a = 1 then

f(x) = (x + 3)(x + 5) (expand factors)

f(x) = x² + 8x + 15

thus, 15 is the constant term
