Answer 2

Answer: 8:19 ✅

Step-by-step explanation:

Hii, let me help you out! ^^

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

⚜ Part 1 - #of Students ⚜

First we should find the total number of students. This can be done by adding the number of boys in this particular math class plus the number of girls in that same class. This is shown below.

[tex]\boldsymbol{Number\;of\,students=\quad Number\;of\;Girls+\;Number\;of\;boys}[/tex]

The number of girls is 11, and the number of boys is 8. Now, it's just a matter of sticking in the known values.

[tex]\multimap\quad \tt 8+11=19\;Students[/tex]

[tex]\large\text{Part 1 is Successfully Completed!}[/tex]

⚜Part 2 - Ratio ⚜

Let's set up a ratio of boys to the total number of students.

This is shown below:

[tex]\boldsymbol{Boys:Total\:\#\;of\;students}[/tex]

Once again, this is simply a matter of sticking in the known values.

[tex]\multimap\quad \tt 8:19[/tex]

[tex]\large\text{Part 2 is Successfully Completed!}[/tex]

What's more, we found the ratio, which is what we needed! (:

Voila! There's our answer, cheers! (:

Answer:

A

Step-by-step explanation:

Use the Pythagorean Theorem: a^2 + b^2 = c^2

The cable will be the hypotenuse, so c = 11.3 m

One leg is the distance of the anchor, so a = 4.2 m

(4.2)^2 + b^2 = (11.3)^2

17.64 + b^2 = 127.69

Subtract 17.64 from both sides

b^2 = 110.05

Square root both sides

b = ~10.5 m

Answers

Answer: [tex]x=-\frac{5}{4}[/tex] and [tex]x=-2[/tex]

Step-by-step explanation:

To factor an equation in the form of [tex]ax^2+bx+c[/tex] you need to find the value of [tex]ac[/tex]. So first solve for that

[tex](4)(10) = 40[/tex]

Now we need to find two numbers that add up to b and multiply together to make ac. In this case those numbers are 5 and 8 since 5+8=13 and (5)(8)=40

Now split 13x into 5x+8x and solve by grouping

[tex]4x^2+5x+8x+10\\(4x^2+5x)+(8x+10)[/tex]

Factor out the GCF in each quantity

[tex](4x^2+5x)+(8x+10)\\x(4x+5)+2(4x+5)[/tex]

Now group x+2 together

[tex](x+2)(4x+5)[/tex]

Finally, set each factor equal to 0 and solve for x

[tex]x+2=0\\x+2-2=0-2\\x=-2\\\\\\4x+5=0\\4x+5-5=0-5\\4x=-5\\\frac{4x}{4} =\frac{-5}{4} \\x=-\frac{5}{4}[/tex]

The boarding platform of a Ferris wheel is 4 meters above the ground and the Ferris wheel is 24 meters in diameter and spins once every 7 minutes. How many minutes of the ride are spent higher than 22 meters above the ground

Answers

The number of minutes of the ride that are spent higher than 22 meters above the ground is; 2.64 minutes

How to find the number of revolutions?

We are given;

bottom of the Ferris Wheel is 4 meters off the ground.

Radius = diameter/2 = 24/2; r = 12 meters.

Thus, the center of the Ferris Wheel is 4 + 12 = 16 meters off the ground.

A horizontal line through the center of the Ferris Wheel is 16 meters off the ground, and therefore the lower half of the Ferris Wheel is always below 22meters.

The distance from the horizontal to 22 meters is 22 - 16 = 6 meters.

The angle between the horizontal and a radius to 22 meters is;

sin(θ) = 6/16

θ = sin⁻¹(6/16)

θ = 22.02°.

This angle height is on both sides of the Ferris Wheel and as such;

180° + (2 * 22.02) = 224.04° is always under 16 meters.

Thus, what is above 16 meters is 360° - 224.04° = 135.96°

Since it takes 7 minutes for 1 revolution, then the amount of time the Ferris Wheel is above 16 meters is;

(135.96/360) * 7 min ≈ 2.64 minutes

A five-digit integer will be chosen at random from all possible positive five-digit integers. What is the probability that the number's units digit will be less than 5

Answers

The probability that the number's units digit will be less than 5 is 0.5 that it is equal to 1/2.

Probability is a branch of mathematics concerned with numerical descriptions of how likely an event is to occur or how likely a statement is to be true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

There are 10 possible digits, 0, 1, 2, ... 9 that make up the 5-digit number made up of integral values.

There are 5 digits that are less than 5 which are 0, 1, 2, 3, and 4 so the probability will be found by taking only those nubers which have unit's place less than 5,

By probability formula , Probability= no. of favourable outcomes/total no. of outcomes

So probability will be found that will be equal to 5/10, or 1/2

Given triangle ABC, A=105°, a=10cm, b=7cm, find B,C and c.

Answers

The value of the side c will be 5.56 cm and angle C is 32.49° and angle B is 42.51°.

What is law of cosine?

Let there is a triangle ABC such that |AB| = a units, |AC| = b units, and |BC| = c units and the internal angle A is of θ degrees, then we have:

a² + b² – 2ab cos C = c²

Given triangle ABC, A = 105°, a = 10 cm, b = 7 cm.

Then we have

7² + c² – (2 · 7 · c) cos 105° = 10²

c² + 3.62c – 51 = 0

On solving, we have

c = 5.56

Then the angle C will be

10² + 7² – 2 · 7 · 10 · cos C = 5.56²

                149 – 140 cos C = 30.91

                                 cos C = 0.8435

                                        C = 32.49°

We know that

       ∠A + ∠B + ∠C = 180°

Line segment KL is tangent to circle J at point K.

Circle J is shown. Line segment J K is a radius with length r. Line segment K L is a tangent with length 24 and it intersects the circle at point K. A line is drawn from point L to point J and goes through a point on the circle. The length from point L to the point on the circle is 16. The length from the point on the circle to center point J is r.

What is the length of the radius, r?

Answers

Using the tangent theorem, the length of the radius is: B. 10 units.

What is the Tangent Theorem?

According to the tangent theorem, since KL is tangent to the circle, therefore, angle JKL = 90°.

Since the triangle is a right triangle, apply the Pythagorean theorem:

(r+16)² = r² + 24²

r² + 32r + 256 = r² + 576

r² - r² + 32r + 256 = 576

32r + 256 = 576

32r = 576 - 256

32r = 320

Which statement compares the graph of the two functions?

First, a vertical shift of N units is written as:

g(x) = f(x) + N

if N > 0 the shift is upwards.If N < 0 the shift is downwards.

A horizontal shift of N units is written as:

g(x) = f(x + N).

if N < 0, the shift is to the right.If N > 0, the shift is to the left.

In this case, we have:

The length of a rectangle exceeds its width by 4
inches, and the area is 60 square inches. What
are the length and width of the rectangle?

Answers

Answer:

length = 10 in, width = 6 in

Step-by-step explanation:

Let the width be x.

Then, length = (x+4)

Area = 60 in²

Area of a rectangle = width × length

60 = x × (x+4)

60 = x² + 4x

x² + 4x - 60 = 0

Splitting the middle term :-

x² + 10x - 6x - 60 = 0

x (x + 10) - 6 ( x + 10) =0

(x + 10) ( x - 6)

x = -10 (doesn't fulfill our requirement)

x = 6

So, width = 6 in

length = 6+4 = 10 in

If 343 superscript x baseline = 49 superscript 4 minus x, what is the value of x?

Answers

The value of x is 8/5 or 1.6 when 343ˣ = 49⁴ ⁻ ˣ, using the laws of exponents.

Exponents are of the form aˣ, read as "a to the power of x", and signify the product of a multiplied by itself x number of times.

In the question, we are given that 343ˣ = 49⁴ ⁻ ˣ, and are asked to find the value of x.

We try to solve the exponential equation, using the laws of exponents in the following way:

343ˣ = 49⁴ ⁻ ˣ,

or, (7³)ˣ = (7²)⁽⁴ - ˣ⁾ {Since, 343 = 7³ and 49 = 7²}.

or, 7³ˣ = 7⁸ ⁻ ²ˣ {Using the law: [tex](x^{a})^{b} = x^{ab}[/tex]},

or, 3x = 8 - 2x {Using the law: [tex]x^a = x^b \Rightarrow a = b[/tex], when x ≠ 0}.

or, 3x + 2x = 8 - 2x + 2x {Adding 2x to both sides of the equation},

or, 5x = 8 {Simplifying}

or, 5x/5 = 8/5 {Dividing both sides by 5},

or, x = 8/5 or 1.6 {Simplifying}

Therefore, the value of x is 8/5 or 1.6 when 343ˣ = 49⁴ ⁻ ˣ, using the laws of exponents.
