For this case we must simplify the following expression:
[tex]\frac {6-3 \sqrt [3] {6}} {\sqrt [3] {9}}[/tex]
Multiplying the numerator and denominator by[tex](\sqrt [3] {9}) ^ 2[/tex]
[tex]\frac {6-3 \sqrt [3] {6}} {\sqrt [3] {9}} * \frac {(\sqrt [3] {9}) ^ 2} {(\sqrt [3] { 9}) ^ 2} =[/tex]
We rewrite:
[tex]\frac {\frac {6-3 \sqrt [3] {6}} * (\sqrt [3] {9}) ^ 2} {\sqrt [3] {9} * (\sqrt [3] {9 }) ^ 2} =[/tex]
By properties of powers we have that:
[tex]a ^ m * a ^ n = a ^ {m + n}\\\frac {(6-3 \sqrt [3] {6}) * (\sqrt [3] {9}) ^ 2} {(\sqrt [3] {9}) ^ 3} =\\\frac {(6-3 \sqrt [3] {6}) * (\sqrt [3] {9}) ^ 2} {9} =[/tex]
We rewrite, moving the exponent within the radical:
[tex]\frac {(6-3 \sqrt [3] {6}) * \sqrt [3] {9 ^ 2}} {9} =\\\frac {(6-3 \sqrt [3] {6}) * \sqrt [3] {81}} {9} =[/tex]
We can rewrite[tex]3 * 3 ^ 3 = 81[/tex]
[tex]\frac {(6-3 \sqrt [3] {6}) * \sqrt [3] {3 * 3 ^ 3}} {9} =[/tex]
We simplify:
[tex]\frac {(6-3 \sqrt [3] {6}) * 3 \sqrt [3] {3}} {9} =[/tex]
We apply distributive property:
[tex]\frac {18 \sqrt [3] {3} -9 \sqrt [3] {18}} {9} =[/tex]
Simplifying we finally have:

What is 5.193 rounded to the nearest hundredth?
Is it
5.19 is the answer x hope it helped
5.193 rounded to the nearest hundredth is 5.19.
Given is a decimal number 5.193 we need to round to the nearest hundredth,
To round a number to the nearest hundredth, you need to look at the digit in the thousandth place (two decimal places to the right of the decimal point).
In the case of 5.193, the digit in the thousandth place is 3. To round to the nearest hundredth, we follow the following rule:
If the digit in the thousandth place is less than 5, we round down (keep the same value).
If the digit in the thousandth place is 5 or greater, we round up (increase the value by 1).
Since 3 is less than 5, we round down.
Therefore, 5.193 rounded to the nearest hundredth is 5.19.

carol and chick are counting calories ehile eating lunch at the school cafeteria in one week carol had 8 slices of pizza,5containers of skim milk and five cups of fruit salad. chick had 5 slices pf pizza,7 containers of fruit salad, and 7 containers of skim milk. chicks calorie count was 2500 and carols was 3070. if each container of skim milk is 40 calories how many calories did carol get from pizza
Answer:
2320 calories
Step-by-step explanation:
We are given the following information;
Carol;
8 slices of pizza
5 containers of skim milk
5 cups of fruit salad
Chick;
5 slices pf pizza
7 containers of skim milk
7 containers of fruit salad
We let x denote the calories in each slice of pizza and y the calories in each cup or container of fruit salad. Chicks calorie count can thus be represented by the following expression;
5x + 7(40) + 7y
5x + 7y + 280
We are also informed that chicks calorie count was 2500 and thus the following equation is formed;
5x + 7y + 280 = 2500
5x + 7y =2220. This will be our first equation
On the other hand, Carols calorie count can be represented by the following expression;
8x + 5(40) + 5y
8x + 5y + 200
We are also informed that Carols calorie count was 3070 and thus the following equation is formed;
8x + 5y + 200 = 3070
8x + 5y = 2870. This will be our second equation
Now, we have two sets of equation;
5x + 7y =2220
8x + 5y = 2870
We solve these simultaneously to determine the values of x and y;
We multiply the first equation by 8 and the second by 5 in order to eliminate x and solve for y;
40x + 56y = 17760
40x + 25y = 14350
Subtracting the second equation from the first yields;
31y = 3410
y = 110
We substitute this value in the first equation and solve for x;
5x + 7(110) = 2220
5x = 2220 - 770
5x = 1450
x = 290
Therefore, each slice of pizza contains 290 calories. Carol had 8 slices of pizza implying that her total calories count from pizza was;
8 * 290 = 2320 calories

Suppose you can chose from 3 different shirts, 2 pairs of pants, and 5 pairs of shoes. Use the fundamental counting principle to find out how many different outfit combinations you can make.
Answer:
You can make 10 combinations.
Step-by-step explanation:
you can make 10 combinations because all you have to do is just add all the numbers then you get 10
We want to find the total number of combinations of outfits, given that we know the number of each type of clothes that you have.
Using basic counting, we will get that there are 30 different outfit combinations.
Let's see how to get that:
To count the total number of combinations, the first thing we need to find is the selections.
Here we have 3 selections:
Selection of shirtSelection of pantsSelection of shoes.Now we need to find the number of options for each one of these selections:
Selection of shirt (3 options)Selection of pants (2 options)Selection of shoes. (5 options)To get the total number of combinations, we just need to multiply all of these numbers of options, we will get:
3*2*5 = 30
This means that there are 30 different outfit combinations.

How to find the surface area of a box and the volume?
for surface area you find the area of a square face (11*9=99) but there are 2 square faces so it would be 2 lots of 99 (99*2=198)
then you find the area of the rectangle faces (12*9=108)
there are 4 rectangle faces so you would do 108*4=432
then just do 432 + 198 =630
so surface area is 630
for volume you do b*l*h
so just do 11*9*12
= 1188
so volume is 1188cm^3
Find the volume of the cone of with a height of 6cm and a diameter of the base or 6cm
Answer:
The volume of cone v= 113.04 cm³.
Step-by-step explanation:
Formula used to find volume of cone is:
[tex]v= \pi * r^2 * \frac{h}{3}[/tex]
where r is the radius and h is the height of cone.
In the given question we are given:
height h= 6 cm
diameter d= 6 cm
We know radius r = d/2 = 6/2 = 3 cm
so, volume will be:
[tex]v= \pi * 6^2 * \frac{3}{3}[/tex]
[tex]v= \pi * 36 [/tex]
[tex]v=113.04[/tex]
So, the volume of cone v= 113.04 cm³ given height h= 6cm and radius r= 3cm
find the midpoint of the segment with the following endpoints (2,4) and(8,8)
Answer:
(5,6)
Step-by-step explanation:
just answered a similar question for you a while ago so I have updated by response to match the different values:
the midpoint formula is
(x1 + x2/2) , (y1 + y2/2) <-- both the x1 and y1 coordinates also are divided by 2
so to solve for the midpoint, we take our endpoints and plug it into the formula
we will list the coordinates as the following to plug it into the formula:
x coordinate 1 = 2
x coordinate 2 = 8
y coordinate 1 = 4
y coordinate 2 = 8
substituting these values into the formula we get this:
x =(2 + 8/2) , y = (4 + 8/2)
x = 2 + 8 = 10/2 = 5 which is our x coordinate for the midpoint
y = 4 + 8 = 12/2 = 6 which is our y coordinate for the midpoint
in an ordered pair it would be (5, 6)
Final answer:
The midpoint of the segment with the endpoints (2,4) and (8,8) is (5, 6).
Explanation:
The midpoint of a line segment is the point that is equidistant from both endpoints. To find the midpoint of a segment with endpoints (2,4) and (8,8), we can use the midpoint formula.
The midpoint formula is given by:
M = (x1 + x2)/2, (y1 + y2)/2
Using the given endpoints, we substitute the values into the formula:
M = (2 + 8)/2, (4 + 8)/2 = (10/2, 12/2) = (5, 6)
Therefore, the midpoint of the segment with the given endpoints is (5, 6).

find a non-zero value of K such that kx^2+ 8x+8+= 0 has only one solution. What is the solution?
kx² + 8x + 8 = 0
We want this to have just one solution, we know this equation:
x = (-b ± √Δ)/2a
So if Δ = 0 we have just one solution.
Δ = b² - 4.a.c
0 = 8² - 4.k.8
0 = 64 - 32k
32k = 64
k = 2
2x² + 8x + 8 = 0
x² + 4x + 4 = 0
(x + 2)² = 0
x + 2 = 0
x = -2
The solution is -2.
The non-zero value of k for which the quadratic equation kx²+8x+8=0 has only one solution is '1'. This is arrived at by setting the discriminant of the quadratic equation (b² - 4ac) to zero and solving for 'k.'
Explanation:The subject of this question is a mathematical concept known as a discriminant in a quadratic equation. A quadratic equation is generally in the form of ax²+bx+c = 0. The discriminant of the quadratic equation kx²+8x+8=0 is given by the formula b²-4ac, where 'a is the coefficient of x² (which is 'k' in this case), 'b' is the coefficient of x, and 'c' is the constant term. The discriminant must equal zero for the quadratic equation to have only one solution. Therefore, we have 8² - 4*k*8 = 0. Solving this equation gives k = 1, which is a non-zero value.

$ 140 --------------> 1
x ------------------>[tex]\frac {1} {7}[/tex]
Where "x" represents the amount of money spent on dairy products.
[tex]x = \frac {\frac {1} {7} * 140} {1}\\x = 20[/tex]

Write the standard equation for the circle center (-6,8) that passes through (0,0)
Answer:
D
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (- 6, - 8), thus
(x + 6)² + (y + 8)² = r²
The radius is the distance from the centre to a point on the circle
Calculate r using the distance formula
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 6, - 8) and (x₂, y₂ ) = (0, 0)
r = [tex]\sqrt{(0+6)^2+(0+8)^2}[/tex] = [tex]\sqrt{36+64}[/tex] = [tex]\sqrt{100}[/tex] = 10
Hence
(x + 6)² + (y + 8)² = 100 → D
