How do you find the value of X step by step?

Answer:

Since its a cube and a sphere just fits in side it we know that both the sphere and the cube are 21cm wide and since its a cube the dimensions of the cube is 21*21*21 giving you 9,261 cm³ then you find the volume of the V=4/3π10³≈4849.04826 now all you have to do is subtract your two totals to get 4411.95174

Answer:

35,295.6 cm^3 to the nearest tenth.

Step-by-step explanation:

The diameter of the sphere = 2*21 = 42.

The volume of the box = 42^3 ( because the dimensions of the box = the diameter of the sphere).

The volume of the sphere = 4/3 π r^3

= 4/3 π 21^3

So the empty space = 42^3 - 4/3 π 21^3

= 35295.615 cm^3.

Answer:

m = 56

Step-by-step explanation:

The same way you would solve an equation.

m/-14 < -4

multiply both sides by -1

-1(- m/14) < -1 (-4)

since you are multiplying by a negative number, invert the inequality sign

m/14 > 4

multiply both sides by 14

m = 4 * 14

m = 56

Answer:

y=-2x+11

Step-by-step explanation:

Slope-intercept form is y=mx+b.

Slope is rise/run, which is y2-y1/x2-x1. Using these points, that's (13-5)/(-1-3). This is 8/-4, or -2.

You can plug this into y=mx+b to get y=-2x+b.

To solve for b, you can use one of the original points and plug it back into the formula:

y=-2x+b

5=-2(3)+b

5=-6+b

b=11

So, putting it all together, you get y=-2x+11.

Let m = slope

m = (13 - 5)/(-1 - 3)

m = 8/-4

m = -2

Now use the point-slope formula.

Here is the formula: y - y_1 = m(x - x_1).

y - 5 = -2(x - 3)

y - 5 = -2x + 6

y = -2x + 6 + 5

y = -2x + 11

Done.

Answer:

8.7%

Step-by-step explanation:

the formula for  % error is = [ (approx. - exact ) / exact ] x 100

so, we know the approx value was 250 while the exact one is 230

thus; [ ( 250-230 ) / 230 ] x 100

= 8.7%

Answer:

MN = 4 units

m<MLN = 42 degrees

Step-by-step explanation:

For this problem, we need to know the definition of congruence. Two shapes are said to be congruent if the angles and sides have the exact same measurements.

We are given that these two triangles are congruent, so we know they are the same. XYZ ~= NML

Since we know this, we simply rotate the triangles to be the same to know the measurements.

We know that XY = MN = 4 units.

We know that m<YZX = m<MLN = 42 degrees.

So, these are the solutions.

Cheers.

Answer:

Diameter of the circle = 5.0 unit

The length of the chain = 40 units

Step-by-step explanation:

Given

Number of thin gold circles used for making bracelet is equal to 8

Radius of the circle = 2.5 units

Diameter of the circle = 2 * Radius of the circle

Diameter of the circle = 2 * 2.5 = 5.0 unit

The length of the chain = 8 * diameter = 8 * 5 = 40 units

Answer:

the trid one becasue

Step-by-step explanation:

To get the correct answer, you can count the total number of shaded tenths and the total number of shaded hundredths and then regroup.

There are 9 shaded tenths and 18 shaded hundredths. Regroup 10 hundredths into 1 tenth to get 10 tenths and 8 hundredths. Then regroup the 10 tenths in one whole, giving you 1 whole and 8 hundredths. The product is 1.08.

Another way to get the answer is to count the total number of shaded hundredths. There are 108 hundredths. Regroup 100 of them as one whole, giving you 1 whole and 8 hundredths.

Option A is correct, the product of (√14 - √3) (√12+√7) is 2√42-7√2-6-√21

An expression is combination of variables, numbers and operators.

We need to find the product of (√14 - √3) (√12+√7)

Let us apply distributive property to solve this

√14(√12+√7)  - √3(√12+√7)

√14.√12 + √14√7 -√3√12-√3√7

√168 + √98 -√36 -√21

168 can be written as 4 times of forty two.

98 can be written as forty nine times of 2.

So we get

2√42-7√2-6-√21

Hence, Option A is correct, the product of (√14 - √3) (√12+√7) is 2√42-7√2-6-√21

Step-by-step explanation:

Perimeter of a triangle equals side 1 plus side 2 plus side 2

           P = s1 + s2 + s3                 side 1 = side 2 =  x

                                                     x/side 3 = 5 / 3

                                                     x  = (5/3) side 3

                                                     x (3/5)  = side 3

                                                     perimeter = 65    slove for x

          65  = x + x + 3x/5

         325  = 5x + 5x + 3x

         325  = 13X

          25   = x    equal side 1 and side 2  

          side 3 = 25(3/5)  = 15

Answer:

Part A

The first thing we must do for this case is to rewrite both expressions.

We have then:

1/2 (7x + 48) = (7/2) x + 24

- [1 / 2x - 3] + 4 (x + 5) = - (1/2) x + 3 + 4x + 20 = (7/2) x + 23

Answer:

We note that the first expression is greater than the second for all values of x.

Part B:

A new expression that is greater than both written expressions is:

(7/2) x + 25

For all values of x, this expression is always greater.

Answer:

(7/2) x + 25

Answer:

Total credit hours a student have = 2.5 hours.

Step-by-step explanation:

P.S - The exact question is -

Given - The tuition costs, C, for a local community college are modeled by C(h) = 250 + 200h, where h represents the number of credit hours taken. The local state university has tuition costs, S, modeled by the function S(h) = 300 + 180h.

To find - How many credit hours will a student have to take for the two tuition costs to be equal.

Proof -

If the two tuition cost are equal, then

C(h) = S(h)

⇒250 + 200h = 300 + 180h

⇒200h - 180h = 300 - 250

⇒20h = 50

⇒2h = 5

⇒h = [tex]\frac{5}{2}[/tex]

⇒h = 2.5

∴ we get

Total credit hours a student have = 2.5 hours.
