The volume of the scoop of ice cream is 14.14 cm³.

The height of the cone that would fit all the ice cream is  6 cm.

In order to determine the  volume of the scoop of ice cream, the formula for the volume of a sphere would be used.

Volume of a sphere = 4/3 x pi x r^3

= 4/3 x 22/7 x 1.5^3 = 14.14 cm³

The formula that can be used to determine the height of the cone is:

Volume of the scoop / (1/3 x π x r²)

14.14 / (1/3 x 1.5² x 22/7) = 6 cm

Step-by-step explanation:

Area of one triangle = 6*16/2 = 48 cm²

Lateral Surface Area = Are of 4 traiangles = 4*48 = 192 cm²

Area of the bottom square = 6 * 6 = 36 cm²

Using the probability concept, it is found that considering that a customer got their car washed on Friday, the probability that the customer selected the deluxe car is given by: 55.8%.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, on Friday, there were 77 washed, of which 43 were deluxe, hence:

p = 43/77 = 0.558 = 55.8%

Answer:

Yes and no

Step-by-step explanation:

Prime numbers greater than 2 are always odd because if they were even they would be divisible by 2, becoming composite. Not all composite numbers are even, some may be a multiple of two odd numbers. For example, 21 = 3*7

The equivalent fraction to 3 is only 3/1

Step-by-step explanation:

[tex] \sf g(n) = 10n - 10 \Rightarrow g(x) = 90[/tex]

Let's find x

[tex]\sf \to g(x) = 90[/tex]

$\sf \to 10x - 10 = 90$

$\sf \to 10x - 10 + 10 = 90 + 10$

$\sf \to 10x + 0 = 100$

$\sf \to 10x = 100$

$\sf \to x = \frac{100}{10}$

Answer:

To prove V is a subspace of R, you must show:

(1) It is not empty

(2) Adding vectors returns real numbers

(3) Multiplying by scalars return real numbers

2 & 3 follow the conditions that x,y must be real.

===

(1):

0 = 0 + 0 , therefor V cannot be an empty set. Really thats it.

===

(2)

Let u=(u1, u2 , 2u1-3u2)

Let v *lowercase =(v1, v2, 2v1-3v2)

Great, now lets add them. This isn't intuitive unless you finish reading it all.

u+v = ( u1 + v1 , u2 + v2 , 2u1 - 3u2 + 2v1 - 3u2 )

--> u + v = [ (u1+v1), (u2+v2) , (2u1 + 2v1) + (-3u2 - 3v2) ] (got like terms kinda)

====> All must equal (x,y, 2x-3y)

... which means x=u1+v1 & y=u2+v2 (you compare u+v to V for this)

===

(3)

Let c be a real number.

C(u) = (Cu1, Cu2, C2u1 - C3u2)

====> Must equal (x,y, 2x-3y)

... which means Cu1 = x & Cu2 = y

Cu is in V (because x,y are)

-> V is a subspace of R3.

Graphs are used to represent functions and equations

The best value of x is x = 5

From the question, we understand that x represents the unit of calculating the resale in plot million of rands

This means that x cannot be negative.

So, we have x = 2 and x = 5

The graph is not given.

So, we can assume that the graph is a linear function with a positive slope

For a linear function with a positive slope, the higher the x value, the higher the output value

Hence, the best value of x is x = 5

Answer:

length of short piece = 14ft

length of long piece = 38ft

Step-by-step explanation:

s: short piece, l: long piece

52 = s + l

s = ((52 - 10)/3)

s = (42/3)

s = 14

l = 2s + 10

l = (2 x 14) + 10

l = 28 + 10

l = 38

52 = s + l

52 = 14 + 38

52 = 52

Answer:

x - 2y = 4

Step-by-step explanation:

Parallel lines have equal slopes.

The given line has a slope of 1/2

so the required line is

y = -5 + (1/2) (x + 6)

Multiply by 2 on both sides,

2y = -10 + x + 6

so

x - 2y = 4

Replace x and solve:

Step-by-step explanation:

The volume of the cube is the total amount of cubes in the box.

Because the box is a cube, and you know the formula for volume of cube is  L³

L³=125

∛L³=∛125

L=5

there would be 25 cubes in each layer, not 125. Because one layer is L²

Answer:

x= 25

Step-by-step explanation:

5x + (3x+7) + 96 + (180-123) = 360°  .. sum of interior angles

8x = 200

x = 25

Answer:

x = 25°

Step-by-step explanation:

First, let us find the value of y. ( Refer to the attachment )

We know that,

Angles in a straight line are added up to 180° degrees.

Therefore,

123 + y = 180

y = 180 - 123

y = 57°

And now let us find the value of x.

We know that,

The sum of the interior angles in a quadrilateral is 360°.

Therefore,

96 + 5x + 3x + 7 + 57 = 360

160 + 8x = 360

8x = 360 - 160

8x = 200

x =  25°
