Answer:
Surface Area = 560.41 cm2
Volume (if it's a sphere) = 9979.71 cm3 or around 10 liters
Step-by-step explanation:
1. The circunference formula is C = 2 * π * R
2. If C = 83.92cm, R is 13.356 cm --> R = C / (2π)
3. The surface area formula is A = π * R * R
4. For R = 13.356 cm, A = 560.41 cm2
5. Sphere volume is V = (4/3) * π * R * R
6. For R = 13.356 cm, V = 9,979.71 cm3
7. 1,000 cm3 = 1 liter, so V is aprox. 10 Liters

At an ice carving competition, each carver starts with a block of ice with the dimensions shown. The block is wrapped in a special reflective material to keep it from melting before the competition starts.
Answer:
52 square feet
Step-by-step explanation:
Given
See attachment for block
Required
How much reflective material is needed (without overlapping)
The question implies that, we calculate the surface area of the material.
Without overlapping, the material will have the same surface area as the block of ice.
The surface area is calculated using:
[tex]SA = 2 * (LW + WH + HL)[/tex]
Where
[tex]W = 4[/tex] --- Width
[tex]L = 2[/tex] --- Length
[tex]H = 3[/tex] --- Height
So, we have:
[tex]SA = 2 * (2 * 4 + 4 * 3 + 3 * 2)[/tex]
[tex]SA = 2 * (8 + 12 + 6)[/tex]
[tex]SA = 2 * 26[/tex]
[tex]SA = 52[/tex]

Answer:
508sq. cm
Step-by-step explanation:
surface area of a prism = 2(lw + wh + lh)
For the larger prism
Surface area = 2(2*10 + 2 * 12 * 10*12)
Surface area = 2(20+24+120)
Surface area = 2(164)
Surface area = 328sq.cm
For the smaller prism
Surface area = 2(3*6 + 3 * 8 * 6*8)
Surface area = 2(18+24+48)
Surface area = 2(90)
Surface area = 180 sq.cm
Surface area of the figure = 328 + 180
Surface area of the figure = 508sq. cm

A carpet company charges $4 per square foot plus a $100 installation charge. Write an expression for the total cost of x square feet of carpet.
Answer: 4x + 100
Step-by-step explanation:
The company charges $4 per foot plus an installation charge of $100.
There is therefore both a fixed element and a variable element.
The fixed element is the $100 installation charge
The variable element is 4 * the number of square feet of carpet which is x: 4 * x
Formula puts them together to give:
= Variable cost + Fixed cost
= 4 * x + 100
= 4x + 100

Condense (cos92°)(cos133°)-(sin92°)(sin133°) into a singular trigonometric function expression, then find the exact value.
Answer:
-1/√2
Step-by-step explanation:
According to trigonometry identity
cos(A+B) = cosAcosB - sinA sinB
Given the expression
(cos92°)(cos133°)-(sin92°)(sin133°)
This can be expressed as cos(92+133) where A = 92, B = 133
(cos92°)(cos133°)-(sin92°)(sin133°)
= cos(92+133)
= cos225
= -0.7071
= -1/√2
Hence the exact value is -1/√2

A right cone is shown. The radius of the base is labeled x millimeters. The height is labeled forty millimeters. The slant height is labeled ninety millimeters. Find the value for the unknown measurement in the right cone. Round to the nearest tenth. Enter the correct answer in the box.
Answer:
Radius, x = 80.6mm
Step-by-step explanation:
[tex]radius =\sqrt{height^2 -slant\ height^2} = \sqrt{90^2 - 40^2} = \sqrt{8100-1600} =\sqrt{6500}[/tex]

Wanda uses 3.54 cups of flour to make 6 bagels. Eli uses 2.5 cups of flour to make 5 bagels. How much more flour per bagel is needed for Wanda's recipe?
Answer:
Wanda's recipe needs 0.09 more cups of flour per bagel.
Step-by-step explanation:
First, you have to find the amount flour that each of them need for one bagel by dividing the cups of flour they use by the number of bagels:
Wanda: 3.54/6= 0.59 cups of flour
Eli: 2.5/5=0.5 cups of flour
Now, you have to subtract the amount of flour Eli needs from the amount that Wanda needs:
0.59-0.5=0.09
According to thiss, the answer is that Wanda's recipe needs 0.09 more cups of flour per bagel.

I divided 6394 by 42 but I don’t know the remainder. Does it have one or not?
Answer:
The answer is 152 r10
Step-by-step explanation:
There is indeed a remainder when dividing 6394 by 42.
6394 ÷ 42 = 152 with a remainder of 10, so, the remainder is 10.
Here, we have,
To determine if there is a remainder when dividing 6394 by 42,
we can perform the division and check if the result is a whole number or a decimal.
6394 ÷ 42 = 152 with a remainder of 10
Since the division does not result in a whole number,
but rather a quotient of 152 with a remainder of 10,
it indicates that there is indeed a remainder when dividing 6394 by 42.

Of the pizzas recently sold at Pizza Pies, 10 had pepperoni and 2 did not. Considering this data, how many of the next 6 pizzas sold would you expect to have pepperoni?
Answer:
1 pizza
Step-by-step explanation:
Of the pizzas recently sold at Pizza Pies, 10 had pepperoni and 2 did not.
This means, the total number of pizzas sold is
10 pepperoni + 2 pizzas without pepperoni = 12 pizzas
Hence, the number of 6 pizzas that would be sold without pepperoni is calculated as:
From the above question,
12 pizzas = 2 pizza without pepperoni
6 pizzas = x
Cross Multiply
12 pizzas × x = 6 Pizzas × 2 pizza without pepperoni
x = 6 Pizzas × 2 pizza without pepperoni/12 pizzas
x = 1 pizza without pepperoni
Therefore, 1 pizza would not have pepperoni out of 6 pizzas sold

What is Chi- square test?A chi-squared test (also chi-square or χ2 test) is a statistical hypothesis test that is valid to perform when the test statistic is chi-squared distributed under the null hypothesis, specifically Pearson's chi-squared test and variants thereof. Pearson's chi-squared test is used to determine whether there is a statistically significant difference between the expected frequencies and the observed frequencies in one or more categories of a contingency table.
The data is given as follow:
The experimental weight of cashews = 40 % of 20lbs
= 8
The experimental weight of Brazil Nuts = 15 % of 20lbs
= 3
The experimental weight of Almonds = 20 % of 20lbs
= 4
The experimental weight of peanuts = 25 % of 20lbs
= 5
The observed value is :
Cashews = 5Brazil Nuts= 6Almonds= 5Peanuts= 4So, [tex]{\displaystyle \chi }[/tex] =[tex]\frac{(O-E)^{2}}{E}[/tex]
[tex]{\displaystyle \chi }[/tex]= [tex]\frac{(5-8)^{2}}{8} + \frac{(6-3)^{2}}{3} + \frac{(5-4)^{2}}{4} +\frac{(4-5)^{2}}{5}[/tex]
