Answer: the answer is negative 52          (-52 goes in the box)

Answer is -16

Step-by-step explanation:

The answer is:

The volume of the cylinder is equal to:

[tex]Volume=3096.8cm^{3}[/tex]

To find the volume of the cylinder, first, we need to use the equation to calculate its area to find its diameter, and then, calculate its volume since we know that the height of the cylinder is equal to its diameter.

So,  using the  equation to calculate the area of its base, we have:

[tex]BaseArea=\pi *r^{2}\\\\r=\sqrt{\frac{BaseArea}{\pi } }=\sqrt{\frac{196cm^{2} }{\pi }}\\\\r=\sqrt{\frac{196cm^{2} }{\pi }}=\sqrt{62.4cm^{2}}=7.9cm[/tex]

Therefore, we have that the radius of the cylinder is equal to 7.9 cm, it means that its diameter is equal to:

[tex]diameter=2*radius=7.9cm*2=15.8cm[/tex]

Now that we know the diameter, let's calcule the volume of the cylinder:

[tex]Volume=BaseArea*height=BaseArea*Diameter\\\\Volume=196cm^{2}*15.8cm=3096.8cm^{3}[/tex]

Hence, we have that the volume of the cylinder is equal to:

[tex]Volume=3096.8cm^{3}[/tex]

Have a nice day!

The volume of a cylinder with a base area of 196 cm² and a height equal to the diameter is approximately 2145.74 cm³.

To find the volume of a cylinder with a given base area and a height equal to the diameter, you can use the formula V = πr²h, where π is Pi (approximately 3.14159), r is the radius of the cylinder, and h is the height of the cylinder. The base area of the cylinder (A) is given as 196 cm², which is also equal to πr². Given that the height is equal to the diameter, we can express the height as 2r.

First, you need to solve for the radius (r) using the base area:

A = πr² → r = √(A/π) = √(196 / 3.14159) ≈ 7 cm

Now plug this value into the volume formula:

V = πr²h = π * (7 cm)² * (2 * 7 cm) = π * 49 cm² * 14 cm

Finally, calculate the volume:

V ≈ 3.14159 * 49 cm² * 14 cm ≈ 2145.74 cm³

The volume of the cylinder is approximately 2145.74 cm³.

Answer:

36/39

Step-by-step explanation:

Answer:

The correct option is C.

Step-by-step explanation:

Given information: In DEF, sin D= 36/39.

In a right angled triangle,

[tex]\sin \theta=\frac{perpendicular}{hypotenuse}[/tex]

[tex]\sin D=\frac{EF}{DE}[/tex]

[tex]\frac{36}{39}=\frac{EF}{39}[/tex]

[tex]EF=36[/tex]

[tex]\cos \theta=\frac{base}{hypotenuse}[/tex]

[tex]\cos E=\frac{EF}{DE}[/tex]

[tex]\cos E=\frac{36}{39}[/tex]

The value of cos E is [tex]\frac{36}{39}[/tex]. Therefore the correct option is C.

Answer:

Step-by-step explanation:

took the test

The number of hours in a day is correctly measured in the tens, as a day comprises of 24 hours. This measurement is a human invention rather than a natural observation. Hence true.

The question you've asked is whether the number of hours in a day is measured in the tens. The answer is True. There are 24 hours in a complete day. This measure is not something that naturally exists but rather is a human invention for the purpose of timekeeping. The Babylonians are credited with dividing a circle into 360 degrees, and they chose 24 as it divides neatly into 360, which allows for hours of a reasonable length that can be measured throughout the day. Notably, all days do not have exactly 12 hours of day and 12 hours of night except at the equator, and this occurs every day of the year. Other locations may experience nearly equal amounts of day and night during the equinoxes.

When we say that the number of hours in a day is more than seven hours, we are observing a fact about the number of hours in a day, which is significantly more than seven hours since a full day consists of 24 hours.

Option C

Answer:

[tex] C.676.01 \: {in}^{3} [/tex]

step-by-step explanation :

The volume of the composite solid = volume of the cuboid + volume of the rectangular pyramid

Volume of the cuboid

[tex] = L \times B \times H[/tex]

where

[tex]L = 9 \: inches \\ B = 9 \: inches \\ H = 5 \: inches[/tex]

By substitution,

[tex] \implies \: V = 5 \times 9 \times 9[/tex]

[tex]\implies \: V = 405 \: {in}^{3} [/tex]

Volume of rectangular pyramid

[tex] = \frac{1}{3} \times base \: area \times height[/tex]

[tex]\implies \: V = \frac{1}{3} \times \:( L \times B ) \times \: H[/tex]

[tex] L = 9 \: inches \\ B = 9 \: inches \\ s= 11 \: inches[/tex]

We use the Pythagoras Theorem, to obtain,

h²+4.5²=11²

h²=11²-4.5²

h=√100.75

h=10.03

By substitution,

[tex]\implies \: V = \frac{1}{3} \times \:( 9 \times 9 ) \times \:10.0374[/tex]

we simplify to obtain

[tex]\implies \: V =271.0098 \: {in}^{3} [/tex]

Hence the volume of the the composite solid

[tex]=676.01\: {in}^{3} [/tex]

Answer:

The correct answer is option C.  676.01 in^3

Step-by-step explanation:

It is given a composite solid.

Total volume = volume of cuboid + volume of pyramid

To find the volume of cuboid

Volume of cuboid = Base area * height

Base area = side * side = 9 * 9

Volume = 9 * 9 * 5 = 405 in^3

To find the volume of pyramid

Before that we have to find the height of pyramid

Height² = Hypotenuse² - base² = 11² - 4.5² = 100.75

Height = √100.75 = 10.03

Volume of pyramid = 1/3(base area * height)

  = 1/3(9 * 9 * 10.03) = 271.01 in^3

To find the volume of solid

Volume of solid =  volume of cuboid + volume of pyramid

 = 405 + 271.01 = 676.01 in^3

Therefore the correct answer is option C.   676.01 in^3

To find the original price of a discounted item, divide the price paid by the percentage paid, in decimal form. In this case, $55.25 divided by 0.65 gives $85, which is the original price of the skateboard.

If a skateboard was purchased for $55.25 with a 35% off coupon, then that price represents 65% of the original price (100% - 35% = 65%).

To find the original price, you would take the price paid and divide it by the percentage you paid, in decimal form. In this case, that's 0.65 (65%).

So, the calculation would be $55.25 ÷ 0.65 which gives you approximately $85. This means the original price was $85.

To determine how far Michael will hike in 2 hours, we calculate his hiking rate which is 1.5 miles per hour and then multiply by the total time, resulting in a distance of 3 miles hiked in 2 hours.

To find out how far Michael will hike in 2 hours, we need to set up a proportion based on the information that he hikes 1/4 of a mile every 1/6 of an hour. First, we find the rate at which Michael hikes by dividing the distance by the time:

Rate = 1/4 mile / 1/6 hour = (1/4) * (6/1) = 6/4 = 1.5 miles per hour.

Now, to find out how far he will hike in 2 hours, we simply multiply the rate by the total time:

Distance in 2 hours = 1.5 miles/hour * 2 hours = 3 miles.

Therefore, Michael will hike 3 miles in 2 hours.

We add 27 to both sides of the equation to get:

[tex] {x}^{3} = 27[/tex]

We write 27 as number to exponent 3.

[tex]{x}^{3} = {3}^{3} [/tex]

The exponents are the same.

This implies that, the bases are also the same.

Therefore

[tex]x = 3[/tex]

The answer is:

The equation has only one root (zero) and its's equal to 3.

[tex]x=3[/tex]

We are working with a cubic equation, it means that there will be three roots (zeroes) for the equation.

To solve the problem, we need to remember the following exponents and roots property:

[tex]\sqrt[n]{x^{m} }=x^{\frac{m}{n} }[/tex]

[tex](a^{b})^{c}=a^{b*c}[/tex]

So, we are given the equation:

[tex]x^{3}-27=0[/tex]

Isolating x we have:

[tex]x^{3}=27\\\\\sqrt[3]{x^{3}}=\sqrt[3]{27}\\\\x^{\frac{3}{3} }=\sqrt[3]{(3)^{3} }\\\\x^{\frac{3}{3} }=3^{\frac{3}{3} }\\\\x=3[/tex]

Hence, we have that the equation has only one root (zero) and its's equal to 3.

Answer:

[tex]\sqrt{13}[/tex]

Step-by-step explanation:

Given the vector < a, b > then the magnitude is

[tex]\sqrt{a^2+b^2}[/tex], thus

| (- 3, 2) | = [tex]\sqrt{(-3)^2+2^2}[/tex] = [tex]\sqrt{9+4}[/tex] = [tex]\sqrt{13}[/tex]

The length of the magnitude of the given vector <-3,2> is:

                        [tex]\sqrt{13}[/tex]

We know that for any vector of the type: <a,b>

The magnitude of the length of the vector is given by the formula:

[tex]|<a,b>|=\sqrt{a^2+b^2}[/tex] [tex]\sqrt{13}[/tex]

Here we are given the vector as: <-3,2>

i.e. a= -3

and  b=2.

This means that the length of the magnotude of the vector is given by:

[tex]|<-3,2>|=\sqrt{(-3)^2+(2)^2}\\\\i.e.\\\\|<-3,2>|=\sqrt{9+4}\\\\i.e.\\\\|<-3,2>|=\sqrt{13}[/tex]

Hence, the answer is:  [tex]\sqrt{13}[/tex]

You can find two irrational numbers [tex]r,s[/tex] between 0 and 1.

Then, you'll have

[tex]2016 < 2016+r < 2017,\quad 2016 < 2016+s < 2017[/tex]

And both [tex]2016+r[/tex] and [tex]2016+s[/tex] will be irrational, because they are the sum of a rational number (2016) and an irrational number (r or s).

Finally, in order to find two such numbers, you can start with any irrational number, and scale it down until it lies between 0 and 1.

For example, you can start from [tex]\sqrt{2}\approx 1.4142[/tex] and divide it by any integer greater than 2, say that we choose

[tex]r = \dfrac{\sqrt{2}}{7}[/tex]

[tex]s = \dfrac{\sqrt{2}}{4}[/tex]

So, the two irrational numbers between 2016 and 2017 are

[tex]2016 + \dfrac{\sqrt{2}}{7},\quad 2016 + \dfrac{\sqrt{2}}{4}[/tex]

Two irrational numbers between 2016 and 2017 can be found by adding non-repeating, non-terminating decimals to 2016. Examples include 2016.172 and 2016.399.

Finding irrational numbers between two given numbers involves knowing that irrational numbers are those which cannot be expressed as a quotient of two integers and have non-repeating, non-terminating decimal expansions. Examples of irrational numbers include the square root of non-perfect squares, pi (π), and 'e' (the base of natural logarithms).

Between two such close numbers (like 2016 and 2017), an easy way to find irrational numbers is to add a non-repeating, non-terminating decimal to the smaller number. For instance, let's use 0.172 and 0.399 (which are derived from the reference numbers provided) and add these to 2016:

Both 2016.172 and 2016.399 are irrational numbers that lie between 2016 and 2017.
