Answer:

[tex]351.8mi^2[/tex]

Step-by-step explanation:

Hey there!

Well the formula to find the surface area of a cylinder is,

[tex]2\pi rh+2\pi r^2[/tex],

So with the h and r being 10 and 4 lets plug it in.

[tex]2\pi (4)(10)+2\pi (4)^2[/tex]

Let's solve!

2π40 + 2π16

80π + 32π

251.3 + 100.5

= [tex]351.8mi^2[/tex]

Hope this helps :)

Answer:

351.9 mi^2

Step-by-step explanation:

The surface area of a cylinder can be found using the following formula.

[tex]SA=2\pi r^2+2\pi rh[/tex]

We know that the height of the cylinder is 10 miles and the radius is 4 miles.

h= 10 mi

r= 4 mi

[tex]SA=2\pi (4 mi)^2+2\pi (4 mi)(10 mi)[/tex]

First, evaluate the exponent 4 mi^2.

4 mi^2= 4 mi * 4 mi = 16 mi^2

[tex]SA=2\pi 16 mi^2+2\pi (4 mi)(10 mi)[/tex]

Next, multiply 16 and 2pi

[tex]SA=100.530965 mi^2+2\pi(4 mi)(10mi)[/tex]

Next, multiply 4 and 10

[tex]SA=100.530965 mi^2+2\pi40mi^2[/tex]

Multiply 40 and 2 pi

[tex]SA=100.530965 mi^2+251.327412mi^2[/tex]

Add the 2 numbers together

[tex]SA=351.858377 mi^2[/tex]

Round to the nearest tenth. The 5 in the hundredth place tells us to round the 8 to a 9 in the tenth place.

[tex]SA=351.9 mi^2[/tex]

The surface area of the cylinder is about 351.9 square miles.

Answer:

3 x 10^-1 km per second.

Step-by-step explanation:

A scientific notation includes c x 10^n. c is a number between 1-9, and n is the nth power of 10.

If we move the decimal in 0.3 to the right by 1 place, we can get "c", which will be 3. Since we have moved the decimal to the right, each place moved right counts as -1 for n.

So, the answer is 3 x 10^-1 km per second.

Answer:

D

Step-by-step explanation:

First we need to find out how many miles we can travel using 1 gallon of gasoline. We can easily find that by dividing 78/13 which equals 6. Now we just need to multiply all of the given answers by 6. To be reasonable, since we already know 13*6=78, we should look at the next smallest number and go up from there.

The next smallest number given is 25. 25*6=150.

Answer:

c) quadrant III

Step-by-step explanation:

I will be quick in this question:

[tex]\text {For }y<0 \Rightarrow \text{Quadrant III or Quadrant IV}[/tex]

[tex]\text {For }x<0 \Rightarrow \text{Quadrant II or Quadrant III}[/tex]

What both have in common?

So, the answer is Quadrant III.

Answer:

Quadrant III

Step-by-step explanation:

x < 0 is the area to the left of the y-axis, and y < 0 is the area beneath the x-axis.  This point is therefore located in Quadrant III.

Answer:

10² + 24²

Step-by-step explanation:

The diagram illustrates Pythagoras' identity.

The square on the hypotenuse of a right triangle is equal t o the sum of the squares on the other 2 sides.

A is the square on the hypotenuse, thus

A² = 10² + 24²

Answer:

Step-by-step explanation:

Let side of the square be a

Now, let's find:

Hypotenuse ( h ) = a

Perpendicular ( p ) = 10

Base ( b ) = 24

Applying Pythagoras theorem in the right triangle formed by the square:

[tex] {h}^{2} = {p}^{2} + {b}^{2} [/tex]

plug the values

[tex] {a}^{2} = {10}^{2} + {24}^{2} [/tex]

Hope this helps..

Best regards!!

Answer:

x = 4√3

y = 8√3

Step-by-step explanation:

This is a special 30° 60° 90° right triangle

In this special triangle if the side length that sees 30° is represented by x and the side length that sees 90° is represented by 2x and the side length that sees 60° x√3

Here, the side length that sees 60° is given as 12

12 = x√3 and x = 4√3 therefore y is 8√3

Answer:

angle 8 is the same as angle 1.

Step-by-step explanation:

opposite side exterior angles are congruent

Answer:

2=45, 3=45, 4=135, 5=135, 6=45, 7=135, 8=135

Step-by-step explanation:

Assuming that these lines are parallel, alternate interior angles are supplementary and alternate exterior angles are also supplementary. So, we know that 1=135 so that means we can do 180-135=45 so 2=45. 1 and 4 are equal to each other because of the vertical angle theorem. So every angle is either 45 degrees or 135 degrees. So:

2=3=6=7

1=4=5=8

You can use the theorems to figure out which angles are congruent and which angles are supplementary in a transversal.

I hope this makes sense

Answer:

The answer is option B.

Step-by-step explanation:

Since it's a rectangular prism slicing will produce either a rectangle or trapezoid and not or a circle since it's round

Hope this helps you

Answer: B. Circle

Step-by-step explanation:

Since the base is a rectangle and the faces are rectangular, there is no way to slice the prism to get a a circle.

The trapezoid ? Maybe. A diagonal slice starting on a corner will create a quadrilateral with uneven sides.

Pentagon? Imagine starting on the top near a corner-- but not on the corner-- with a diagonal line, slicing down towards the opposite corner. You should be able to get an irregular pentagon.

A rectangle is easy!

No circles!

Answer: The correct answer is 3.6 miles

Step-by-step explanation:

Answer:

I belive the answer should be B

Answer:

f(x) = 28 + 10x²

For f(1) substitute 1 into f(x)

That's

f(1) = 28 + 10(1)²

= 28 + 10

f(27) = 28 + 10(27)²

Answer:

Length of transverse axis  = 2 b  = 10

Length of conjugate axis   = 2 a  = 4      

Step-by-step explanation:

Explanation:-

Given Hyperbola

                       [tex]\frac{(y+2)^{2} }{25} -\frac{(x-3)^{2} }{4} =1[/tex]

  Standard form of Hyperbola    

                  [tex]\frac{(y-(K))^{2} }{b^{2} } -\frac{(x-h)^{2} }{a^{2} } =1[/tex]

   Center (h , k ) = (3 , -2 )  , a = 2 and b = 5

Length of transverse axis  = 2 b = 2(5) = 10

Length of conjugate axis   = 2 a = 2 (2) = 4      

Answer:

24°

Step-by-step explanation:

Bigger Triangle

180°-94°-41°= 45° ( Angles sum in a triangle)

Smaller Triangle

180° - 45°- 111° = 24° (Angles sum in a triangle)

Therefore X = 24°

Hope this helps.

Answer:

24

Step-by-step explanation:

First we will find the last angle of the big triangle.

1). 94 + 41 + y = 180

   y = 45

Now we know the value of 2 angles in the smaller triangle, so we can find x.

1). 111 + 45 + x = 180

   x = 24

Answer:

Any negative number and 0 works for the expression.

Step-by-step explanation:

Looking at this type of equation, we know that either EVERY negative number and 0 or EVERY positive number and 0 will work for this equation, since nothing is being added and we're just working with absolutes/negatives.

Let's try a random positive number in the expression

[tex]|6| = -(6)\\6 \neq -6[/tex]

So this positive number doesn't work, let's just test with another one.

[tex]|9| = -(9)\\9 \neq -9[/tex]

So we know that positive numbers won't work with this expression.

Let's test 0 quickly, just to make sure.

[tex]|0| = -0\\0 = 0[/tex]

So 0 works.

Let's try a few negative numbers now.

[tex]|-5| = -(-5)\\5 = 5[/tex]

So yes, this does work. Let's try one more negative number.

[tex]|-120| = -(-120)\\120 = 120[/tex]

This works. So, every negative number and 0 work with this equation.

Hope this helped!

Answer:

Lead

Step-by-step explanation:

According to the chart, we can see that lead has the highest number here, so lead has the highest freezing / melting point in this chart.

If we were looking for the element with the lowest freezing / melting point, then we would look for the lowest number, which would belong to Helium, at -272.

Answer:

the third one is the correct answer

Answer:

6 units squared

Step-by-step explanation:

To solve this problem you can solve for the entire area of the square and subtract the area of the unfilled areas for the area of the shaded region..

Area of entire square is 4*4=16

Now for the sections that are unfilled:

4*3/2= 6

1*1/2= 0.5

2*1 = 2

1*1 = 0.5

2*1/2 = 1

Total area of Unfilled region = 6 + 0.5 + 2 + 0.5 +1 = 10

Area of filled region = 16 - 10 = 6 units squared

Answer:

n=16 kg

c=44 kg

Step-by-step explanation:

Let

n=nuts at $2.50 per kg

c=cereal at $1 per kg

n+c=60 (1)

2.5n + c=1.40(60) (2)

From (1)

n=60-c

Substitute n=60-c into (2)

2.5n + c=1.40(60)

2.5(60-c) +c=84

150-2.5c+c=84

-1.5c=84-150

-1.5c= -66

Divide both sides by -1.5

c=44 kg

Substitute c=44 into (1)

n+c=60

n+44=60

n=60-44

=16

n=16 kg

The amount of nuts is 16 kg and cereal mixture is 44 kg to obtain 60 kg of a mix that will sell for $1.40 per kg.
