The surface area of sphere T is 452.16 units squared. The surface area of sphere X is 1808.64 units squared. how many times larger is the radius of sphere X than the radius of sphere T?

Answers

Answer 1

Answer:

the radius of sphere X is 2 times larger than the radius of sphere T

Step-by-step explanation:

Given

Surface area of sphere, T =452.16

Surface area of sphere, X= 1808.64

how many times larger is the radius of sphere X than the radius of sphere T?

Finding radius of both spheres:

Surface area of sphere is given as

A=4πr^2

Now putting value of Ta=452.16 in above formula

452.16=4πrt^2

rt^2=452.16/4π

rt^2=35.98

Taking square root on both sides

rt=5.99

Now putting value of Xa=1808.64 in above formula

1808.64=4πrx^2

rx^2=1808.64/4π

rx^2=143.92

Taking square root on both sides

rx=11.99

Comparing radius of sphere X and the radius of sphere T

rx/rt=11.99/5.99

      = 2.00

rx=2(rt)

Hence the radius of sphere X is 2 times larger than the radius of sphere T!

Answer 2
Hello!

The answer is:

The radius of the  sphere X is 2 times larger than the radius of the sphere T

Why?

To solve the problem, we need to find the radius of both spheres using the following formula:

[tex]Area=\pi *radius^{2}\\\\radius=\sqrt{ \frac{Area}{\pi }}[/tex]

Where,

Area, is the area of the circle.

r, is the radius of the circle.

So,

We are given:

[tex]T_{area}=452.16units^{2}\\X_{area}=1808.64units^{2}[/tex]

Now, calculating we have:

For the sphere X,

[tex]X_{radius}=\sqrt{ \frac{X_{area}}{\pi }}=\sqrt{\frac{1808.64units^{2} }{\pi } }\\\\X_{radius}=\sqrt{\frac{1808.64units^{2} }{\pi }}=\sqrt{575.71units^{2} }=23.99units[/tex]

For the sphere T,

[tex]T_{radius}=\sqrt{ \frac{T_{area}}{\pi }}=\sqrt{\frac{452.16units^{2} }{\pi } }\\\\X_{radius}=\sqrt{\frac{452.16units^{2} }{\pi }}=\sqrt{143.93units^{2} }=11.99units[/tex]

Then, dividing the radius of the X sphere by the  T sphere to know the ratio (between their radius), we have:

[tex]ratio=\frac{23.99units}{11.99units}=2[/tex]

Hence, we have the radius of the sphere X is 2 times larger than the radius of the sphere T.

Have a nice day!

Answers

56 cause u need 12 divide by 0.08 12 times

Answer:

Total charge for wooden pedestal will be $1136

Step-by-step explanation:

Volume of the pedestal will be = volume of cube + volume of the cone

= (Side)³ + [tex]\frac{1}{3}(\pi r^{2}h)[/tex]

= 10³ + [tex]\frac{1}{3}[\pi (\frac{10}{2})^{2}(7)][/tex]

= 1000 + [tex]\frac{1}{3}[\pi 5^{2}(7)][/tex]

= 1000 + [tex]\frac{1}{3}[\pi (25)(7)][/tex]

= 1000 + [tex]\frac{1}{3}[(3.14)(25)(7)][/tex]

= 1000 + 183.17

= 1183.17 cubic inch

Total volume of 12 wooden pedestals = 12 × 1183.17 = 14198 cubic inch

Since charges of the wood is $0.08 per cubic inch

So total charges for pedestal will be = 0.08 × 14198 = $1135.84 ≈ $1136

Juice boxes are sold in a local store for 65 cents each. The factory has $1400 in fixed costs plus 15 cents of additional expense for each juice box made. Assuming all juice boxes manufactured can be sold, find the break-even point.

Answers

Answer:

Production of  2800  juice boxes is the break even point.

Step-by-step explanation:

Break-even point is the point where profit is zero and number of manufactured goods are all sold

Let number of juice boxes be y

charges of local store for 1 juice box= $0.65

charges of local store for y juice box=$0.65y

Factory cost of y juices boxes= $1400 + $0.15y

Assuming all juice boxes manufactured can be sold, to find the break-even point

charges of local store for y juice box= Factory cost of y juices boxes

$0.65y=$1400 + $0.15y

$0.65y-$0.15y= $1400

$0.50y=$1400

y= 1400/0.5

y=2800

hence production of  2800  juice boxes is the break even point!

Factor the polynomial: -x^3-2x^2-3x

Answers

Answer:

-x(x^2+2x+3)

Step-by-step explanation:

Answer:

Step-by-step explanation:

-x is common to all three terms.  Thus, -x^3-2x^2-3x = -x(x^2 + 2x + 3).

Use the quadratic formula to find the roots (and thus the factors) of

x^2 + 2x + 3:  a = 1; b = 2; c = 3.

Thus, the discriminant is b^2-4ac, or 4 - 4(1)(3), or -8.

Because this discriminant is negative, x^2 + 2x + 3 has two complex, unequal roots.  They are:

      -2 ± i√8                  

x = --------------  or  -1 ± i*2*√2

Thus, the three factors of the given polynomial are:

Step-by-step explanation:

APEX

Reflectional symmetry is the quality a design has if it maintains all characteristics when it is (blank) lying in its plane Option: A) rotated about an axis.

What is reflectional symmetry?

Consider a plane. Consider a design or shape on that plane. Now consider an axis.

If we think of that axis as a mirror, and on the opposite side of that axis create the image of the considered shape, then if the shape's image looks exactly as the shape itself, then that shape is called to have a reflectional symmetry.

Instead of that mirror intuition, we can also think that we sort of rotated that image about that considered axis, and after half rotation, the figure is again onto its plane. If that rotated figure looks alike to the initial figure, then that figure has rotational symmetry.

Thus, reflectional symmetry is the quality a design has if it maintains all characteristics when it is (blank) lying in its plane Option: A) rotated about an axis.

The points (0,8),(5,3),(4,2) and (-1,7) are vertices of a rectangle. Determine the coordinates of the midpoints for each side and determine if the midpoints are the vertices of a rectangle

Answers

The area of the triangle is 16. 

You can find this by plotting each of the points and drawing the triangle. You can then use the distance formula to determine each side length. The rectangle will be 2 on one side and 4 on the other. When multiplied together, it will give you the above answer

The coordinates of the midpoints for each side are (2.5, 5.5) , (4.5, 2.5), (1.5, 4.5), and (- 0.5, 7.5).

And, yes, the midpoints are the vertices of a rectangle, as its opposite sides are the same in length.

Use the formula for the midpoint of two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are,

[tex][\dfrac{(x_1 + x_2)}{2} , \dfrac{(y_1 + y_2)}{2} ][/tex]

Given that,

Vertices of the rectangle are (0, 8), (5, 3), (4, 2), and (- 1, 7).

Hence, the coordinates of the midpoints for each side are calculated by using the above formula,

The midpoint of two points (0, 8) and (5, 3) are,

[tex](\dfrac{(0 + 5)}{2} , \dfrac{(8 + 3)}{2} )[/tex]

[tex](2.5, 5.5)[/tex]

The midpoint of two points (5, 3) and (4, 2) are,

[tex](\dfrac{(5 + 4)}{2} , \dfrac{(3 + 2)}{2} )[/tex]

[tex](4.5, 2.5)[/tex]

The midpoint of two points (4, 2) and (-1, 7) are,

[tex](\dfrac{(4 - 1)}{2} , \dfrac{(2 + 7)}{2} )[/tex]

[tex](1.5, 4.5)[/tex]

The midpoint of two points (-1, 7) and (0, 8) are,

[tex](\dfrac{(-1 + 0)}{2} , \dfrac{(8 + 7)}{2} )[/tex]

[tex](-0.5, 7.5)[/tex]

Therefore, the coordinates of the midpoints for each side are (2.5, 5.5) , (4.5, 2.5), (1.5, 4.5), and (- 0.5, 7.5).

When the coordinates of vertices are rectangular then opposite sides are equal to each other.

So, we can check the length of each side of the coordinates of the midpoints (2.5, 5.5), (4.5, 2.5), (1.5, 4.5), and (- 0.5, 7.5).

Used the distance formula,

The distance between two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is,

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

So, The distance between the two points [tex](2.5, 5.5)[/tex] and [tex](4.5, 2.5)[/tex],

[tex]d = \sqrt{(4.5- 2.5)^2 + (2.5 - 5.5)^2}[/tex]

[tex]d = \sqrt{4 + 9}[/tex]

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

The distance between the two points [tex](4.5, 2.5)[/tex] and [tex](1.5, 4.5)[/tex],

[tex]d = \sqrt{(4.5- 1.5)^2 + (2.5 - 4.5)^2}[/tex]

[tex]d = \sqrt{9 + 4}[/tex]

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

The distance between the two points [tex](1.5, 4.5)[/tex] and [tex](-0.5, 7.5)[/tex]

[tex]d = \sqrt{(1.5+ 0.5)^2 + (7.5 - 4.5)^2}[/tex]

[tex]d = \sqrt{4 + 9}[/tex]

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

The distance between the two points[tex](-0.5, 7.5)[/tex] and [tex](2.5, 5.5)[/tex]

[tex]d = \sqrt{(2.5+ 0.5)^2 + (7.5 - 5.5)^2}[/tex]

[tex]d = \sqrt{9 + 4}[/tex]

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

Clearly, All the lengths of each side of the coordinates of the midpoints (2.5, 5.5), (4.5, 2.5), (1.5, 4.5), and (- 0.5, 7.5) are the same.

Hence, it forms a rectangle, as its opposite sides are also the same in length.

How can you find the missing side length of a cube if you know the cube’s volume?

Answers

Answer:

See below

Step-by-step explanation:

In order to solve for the length of a cube, you must already know its width, depth, and volume. Then, arrange the problem as an equation:

Length x width x depth = volume

Next, solve the equation for the length. For example, If I have a cube with a width of 5ft, a depth of 5ft, and a volume of 50ft^3, I will solve for the length by arranging the values to fit the formula shown above:

L x 5 x 5 = 50

Then I'll multiply the values on the left:

25L = 50

And, finally, I will divide either side by 25, which leaves the answer:

To determine (f(a+h) - f(a)) for f(x) = x² + 5x and simplify, we need to substitute x with a+h and a into the function separately and then find the difference. Here are the steps:

Substitute a+h into f(x) to get f(a+h) = (a+h)² + 5(a+h).

What question do you need answered?

Answer:

Option A.

Step-by-step explanation:

Anastasia worked for = 7 hours per day

Number of weeks she worked = 52 weeks

Number of hours she worked = 7×52

= 364 hours

Per hour earning of Anastasia = $20

Total earning of Anastasia = 364×20

= $7280

Let the monthly expenses of Anastasia = $x

Then total expenses = $12x

At the end of the year total saving = Total earning - Total expenses

= $7280 - 12x

Since she saved $2000 in a year therefore, expression that represents the savings will be

2000 = 7280 - 12x

12x = 7280 - 2000

12x = 5280

x = [tex]\frac{5280}{12}[/tex]

x = $440

Option A will be the answer.

Melissa is at the gym for a leg workout. They first start warming up by squatting with only the squat bar (45 lbs): this is an easy task for her. Then, she goes on to the main part of her workout: she squats 5 repetitions of her maximum load (175 lbs), stop to rest for 60 secs, then do so again, for a total of 5 x 5 repetitions. A. In comparison to lifting 45 lbs, what had to happen in Melissas muscle cells to allow her to lift 175 lbs? B. Because the 175-lbs load is very heavy for Melissa, her coach has trained her to start her squat movement in a very specific position (see picture above).
