The answer is:
The third option:
2.7 times as much.
Why?To calculate how many more juice will the new can hold, we need to calculate the old can volume to the new can volume.
So, calculating we have:
Old can:
Since the cans have a right cylinder shape, we can calculate their volume using the following formula:
[tex]Volume_{RightCylinder}=Volume_{Can}=\pi r^{2} h[/tex]
Where,
[tex]r=radius=\frac{diameter}{2}\\h=height[/tex]
We are given the old can dimensions:
[tex]radius=\frac{5.2cm}{2}=2.6cm\\\\height=9.4cm[/tex]
So, calculating the volume, we have:
[tex]Volume_{Can}=\pi *2.6cm^{2} *9.4cm=199.7cm^{3}[/tex]
We have that the volume of the old can is:
[tex]Volume_{Can}=199.7cm^{2}[/tex]
New can:
We are given the new can dimensions, the diameter is increased but the height is the same, so:
[tex]radius=\frac{8.5cm}{2}=4.25cm\\\\height=9.4cm[/tex]
Calculating we have:
[tex]Volume_{Can}=\pi *4.25cm^{2} *9.4cm=533.40cm^{3}[/tex]
Now, dividing the volume of the new can by the old can volume to know how many times more juice will the new can hold, we have:
[tex]\frac{533.4cm^{3} }{199.7cm^{3}}=2.67=2.7[/tex]
Hence, we have that the new can hold 2.7 more juice than the old can, so, the answer is the third option:
2.7 times as much.

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.

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

What is a Circle?A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The circumference of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
The equation of circle is ( x - h )² + ( y - k )² = r²
For a unit circle , the radius r = 1
x² + y² = r² be equation (1)
Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )
Given data ,
The circumference of the Ferris wheel can be calculated using the formula:
C = πd
where d is the diameter of the wheel
C = π x 42 feet
C ≈ 131.88 feet
This means that for each rotation of the Ferris wheel, a passenger will travel approximately 131.88 feet
Since the Ferris wheel rotates 3 times per minute, the distance traveled by a passenger in one minute is
131.88 feet/rotation x 3 rotations/minute = 395.64 feet/minute
Therefore, during a 5-minute ride, a passenger will travel approximately
395.64 feet/minute x 5 minutes = 1,978.2 feet
Hence , the total distance is 1,978 feet

Find the volume of one can
The volume of the cylinder (can of juice) is
[tex]V=\pi r^{2} h[/tex]
we have
[tex]r=3/2=1.5\ in[/tex] ----> the radius is half the diameter
[tex]h=6\ in[/tex]
assume
[tex]\pi =3.14[/tex]
substitute
[tex]V=(3.14)(1.5)^{2} (6)[/tex]
[tex]V=42.39\ in^{2}[/tex]
step 2
Find the total volume of juice in a six-pack
Multiply the volume of one can by 6
[tex]42.39*(6)=254.3\ in^{2}[/tex]
The total volume of juice in a six-pack where each can is 6 inches tall and has a diameter of 3 inches is calculated using the volume of a cylinder formula. The total volume is 254.34 in³. This is achieved by calculating the volume of one can and multiplying by six.
Explanation:To calculate the total volume of juice in a six-pack where each can is 6 inches tall and has a diameter of 3 inches, we first need to find the volume of one can using the formula for the volume of a cylinder, which is V = πr²h. Since the diameter is 3 inches, the radius (r) is half of that, which is 1.5 inches. Plugging the values into the formula, we get:
Calculate the radius (½ of the diameter): 1.5 inchesCalculate the volume of one can: V = π(1.5 inches)²(6 inches)Find the volume: V = 3.14159 × (1.5 inches)² × 6 inches = × 42.39 in³Multiply by 6 to get the total volume for all six cans: Total volume = 42.39 in³ × 6 = 254.34 in³Therefore, the correct answer is 254.34 in³, which represents the total volume for a six-pack of juice cans.
How is the volume of a prism calculated?
add the area of the base to the height
subtract the area of the base from the height
multiply the area of the base by the height
divide the area of the base by the height
Multiply the area of the base by the height
Answer:
C) multiply the area of the base by the height
Step-by-step explanation:
Prism is a three dimensional figures.
The volume of a prism calculated by multiplying the area of the base and the height.
Volume of a prism = Base area * height.
For example:
Volume of a rectangular prism = base area * height = (lw)*h = lwh cubic units
Volume of a cube = Base area * height = (a*a)*a = a^2*a = a^3 cubic units
Volume of a cylinder = Base area * height = (πr^2)*h = πr^2 h
The answer is C) multiply the area of the base by the height
Lucy spends $140 at the grocery store. Dairy items made up 1/7 of her purchase and vegetables accounted for 3/20 of her total. How much money did Lucy spend on items that were not dairy or vegetable items?
For this case we make a rule of three to find the cost of dairy products and vegetables.
$ 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]
So, I spend $ 20 on dairy products.
Now we have:
$ 140 --------------> 1
y ------------------> [tex]\frac {3} {20}[/tex]
Where "y" represents the amount of money spent on vegetables.
[tex]x = \frac {\frac {3} {20} * 140} {1}\\x = 21[/tex]
So, I spend $ 21 on vegetables.
Therefore, I spend $ 41 on vegetables and dairy products.
$ 140- $ 41 = $ 99

The measure of arc BG is 25°
Step-by-step explanation:
we know that
The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.
so
m∠DFC=(1/2)[arc CD+arc BG]
we have
m∠DFC=40°
arc CD=55°
substitute and solve for arc BG
40°=(1/2)[55°+arc BG]
80°=[55°+arc BG]
arc BG=80°-55°=25°

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

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.

Andria is conducting an experiment to determine whether a new medication is effective in reducing swelling. She gets 1,000 volunteers with swelling and divides them into 2 groups. The control group does not receive any medication; the treatment group receives the medication. The patients in the treatment group show reduced signs of swelling. What can Andria conclude from this experiment?
Answer:
The medicine treats swelling
Step-by-step explanation:
"The control group does not receive any medication; the treatment group receives the medication. The patients in the treatment group show reduced signs of swelling. What can Andria conclude from this experiment?"
If she does not give placebo, which she should, then we can only conclude that the medication might be effective. Might, because the thought of the medicine fixing swelling might actually be what helps them.
This takes us to the next topic- placebo experiments.
Most good experiments, to elaborate, are "double blind," one group receives a placebo, and another the medication, and neither know which.
In this case, assuming that the placebo was ineffective, we can conclude that the medicine is effective in treating swelling.
