What is the total surface area (including the area of the floor) of a building shaped as a hemisphere with radius 106 ft ?
Round your answer to the nearest whole number.
Answer:
105897 ft²
Step-by-step explanation:
let, r be the radius, so r = 106 ft
Surface area of a hemisphere,
2πr²+πr²
= 2π×106²+π×106²
= 105897 (rounded to the nearest whole number)

A customer's stock value seems to be rising exponentially. The equation for the linearized regression line that models this situation is log(y) = 0 30x +0 296, where x represents number of weeks. Which of the following is the best approximation of the number of weeks that will pass before the value of the stock reaches $200?
A. 9.3
B. 12.1
C. 6.7
D. 4.8
Given:
The equation for the linearized regression line is:
[tex]\log y=0.30x+0.296[/tex]
where x represents number of weeks and y be the customer's stock.
To find:
The number of weeks that will pass before the value of the stock reaches $200.
Solution:
We have,
[tex]\log y=0.30x+0.296[/tex]
Substituting y=200, we get
[tex]\log (200)=0.30x+0.296[/tex]
[tex]2.301=0.30x+0.296[/tex]
[tex]2.301-0.296=0.30x[/tex]
[tex]2.005=0.30x[/tex]
Divide both sides by 0.30.
[tex]\dfrac{2.005}{0.30}=x[/tex]
[tex]6.6833333=x[/tex]
[tex]x\approx 6.7[/tex]
Therefore, the correct option is C.

Please help me solve this giys
Answer:
(0, -2)
(-3, 1)
(3, -4)
Step-by-step explanation:
The constraints given as;
x + y ≥ -2
3x - y ≤ 2
x - y ≥ -4
Since we want to find vertices of the feasible region, we will ignore the less than or greater than sign and use the equal to sign to some simultaneously.
Let's add first and third constraint together to get;
2x = -6
x = -6/2
x = - 3
Put - 3 for x in equation 1 to get;
-3 + y = -2
y = 3 - 2
y = 1
Thus, vertex here is; (-3, 1)
Lets add first and third equations to get;
4x + 0 = 0
Thus, x = 0
Putting this for x in eq 1;
0 + y = -2
y = -2
vertex here is; (0, -2)
Lets subtract eq 3 from eq 2 to get;
2x = 6
x = 6/2
x = 3
Put 3 for x in eq 3;
x - y = -4
vertex here is; (3, -4)
To paint a wooden cube, Pinocchio needs 4 grams of paint. When it is dry, he cut the cube into 8 smaller pieces of smaller size. How much paint additional paint does Pinocchio need to paint the unpainted surfaces of the smaller cubes
Answer:
9 grams of paint
Step-by-step explanation:
6×8=48
48÷4= 12
48-12=36
36÷4=9
first multiply 6 by 8 because a cube has six faces and you cut that cube eight times
second after you cut that you will have 48 faces and for every six faces there are 4 grams of paint so you divide 48 by 4 and you get 12 this means that 12 of the faces are painted
next you subtract 12 from 48 and you get 36 this means that 36 faces are not painted
lastly you divide 36 by 4 and you will get 9 grams of paint

Lena is asked to write an explicit formula for the graphed geometric sequence.
On a coordinate plane, 3 points are plotted. The points are (1, 1), (2, 2.5), (3, 6.25).
What value, written as a decimal, should Lena use as the common ratio
Answer:
Common Ratio = 2.5
Step-by-step explanation:
Given
Points: (1, 1), (2, 2.5), (3, 6.25)
Required
Determine the common ratio
The points can be rewritten as:
x --- f(x)
1 ---- 1
2 --- 2.5
3 ---- 6.25
The data under the x column are the domain of the function and in this case, they are not needed;
To calculate common ration, Lena should use data in function f(x) column
Common ratio is calculated by dividing a term by the previous term;
Hence;
Common Ratio = 2.5/1 or 6.25/2.5
Common Ratio = 2.5 or 2.5
Notice that, the results are the same;
Hence, the usable common ratio is 2.5
Answer: 2.5 or "C"

I honestly have no clue how to do trig, I need help.
Answer: x= 437.3 ft.
Step-by-step explanation:
Let the angle side at 29 be n
so
n+29 = 90
so, n = 61
now
sin 61= p/h
sin 61 = x/500
so, x = sin 61*500
so, x = 437.3

Your teacher gave you 1/2 of a bag of candy, but she only gave your friend 1/3 of a bag. How much more of the bag did your teacher give you than your friend?
Answer:
We can convert the 2/3 bag of candy that we got to 16/24, by multiplying both the top and bottom by 8. Similarly, we multipy the 1/8 bag of candy that our friend got by 3 on the top and bottom to get 3/24.
We find the difference between these two:
(16/24) - (3/24) = (16-3)/24 = 13/24
So we get 13/24 more of the bag of candy than our friend did.
Answer:
1/6
Step-by-step explanation:
you’re being asked the difference between the amounts of your candy and your friend’s candy.
So you must subtract 1/3 from 1/2.
=> 1/2 - 1/3
=> 3*1 - 2*1/3*2. ( You criss-cross and you multiply the denominators)
=>. 3 - 2 /6
=> 1/6
So you got 1/6 more candies in your bag than your friend.

use other triangle to find hipotenus 48²+36²=x² .... x= 60
(a) Write
[tex] {2}^{5} \div {2}^{5} [/tex]
as a single power if 2.
Answer:
2^0
Step-by-step explanation:
When you are dividing 2 exponents with the same base (in this case, 2) you subtract them. 2^5 ➗ 2^5 => 2^(5-5) = 2^0 => which is equal to 1, but the answer here would be 2^0.
There are two ways to go about this problem.
The first way, the generic way, is to know that,
[tex]\frac{a^n}{a^m}=a^{n-m},a\neq0[/tex].
So,
[tex]\frac{2^5}{2^5}=2^{5-5}=\boxed{2^0}[/tex].
The second way is to realise that both numerator and denominator are equal and when diving two equal numbers you obtain 1. (except when diving zeros) aka,
[tex]\frac{a}{a}=1, a\neq0[/tex]
And 1 equals to any number raised to the power of zero,
[tex]a^0=1,a\neq0[/tex]
So we just have to say that the 1 we got is rewritten as some base to the power of zero.
Since our base needs to be 2, we just simply say,
[tex]2^0[/tex].
Et Viola.
Hope this helps.
QUICK PLZ!!!!! Which graph shows the result of dilating this figure by a factor of One-third about the origin? On a coordinate plane, triangle A B C has points (negative 6, 6), (6, 6), (6, negative 6). On a coordinate plane, triangle A prime B prime C prime has points (negative 2, 2), (2, 2), (2, negative 2). On a coordinate plane, triangle A prime B prime C prime has points (negative 3, 3), (3, 3), (3, negative 3). On a coordinate plane, triangle A prime B prime C prime has points (Negative 18, 18), (18, 18), (18, negative 18). On a coordinate plane, triangle A prime B prime C prime has points (negative 12, 12), (12, 12), (12, negative 12).
Answer:
[tex]A' = (-2,2)[/tex]
[tex]B' = (2,2)[/tex]
[tex]C' = (2,-2)[/tex]
Step-by-step explanation:
Given
[tex]A = (-6,6)[/tex]
[tex]B = (6,6)[/tex]
[tex]C = (6,-6)[/tex]
[tex]k = \frac{1}{3}[/tex]
Required
The new coordinates
To do this, we simply multiply the coordinates of [tex]\triangle ABC[/tex] by the factor of dilation.
i.e.:
[tex]A' = A * k[/tex]
[tex]B' = B * k[/tex]
[tex]C' = C * k[/tex]
So, we have:
[tex]A' = (-6,6) * \frac{1}{3}[/tex]
[tex]A' = (-2,2)[/tex]
[tex]B' = (6,6) * \frac{1}{3}[/tex]
[tex]B' = (2,2)[/tex]
[tex]C' = (6,-6) * \frac{1}{3}[/tex]
[tex]C' = (2,-2)[/tex]
