Answer:
180 units^2
Step-by-step explanation:
The formula to find the area of a sphere is:
A=4(pi)(r)^2
A sphere with radius 2r has an area = 4π(2r)² = 4π.4r² = 16πr²
The ratio of the larger sphere to the smaller = 16πr² : 4πr² = 4 : 1
If the area of the smaller sphere is 45 units then the area of the larger sphere is 45 x 4 = 180 units^2.

Answer:
First, the student performed what was inside of the parentheses and was exponential, which is correct. We know this because of the rules called order of operations, outlined by PEMDAS, which tells us to perform mathematical operations in the following order: parentheses, exponents, multiplication, division, addition, subtraction.
So by the rules I just outlined, next the student should have performed the multiplication, but instead performed subtraction, which is incorrect.
The following is the correct simplification of the expression:
23 - 8 times 2 + 3 by the power of 2
So first we should perform parentheses, but there are none. So we move to the next option in the list, which is exponents, which we do have (3^2).
23 - 8 * 2 + 3^2
23 - 8 * 2 + 9
Next in PEMDAS comes multiplication and division. This means the next step in simplifying the expression is to evaluate 8*2.
23 - 16 + 9
Next in PEMDAS is addition, so we should perform the operation -16 + 9.
23 - 7
Finally, the last step in PEMDAS is to simplify the remaining operation (subtraction).
16
Therefore, the student did the first step correctly but performed the second step incorrectly. The final answer should be 16 after simplification.
Hope this helps!

Find the slope of the line that passes through 4, −6 and −3, 1 . Write your answer in simplest form. Select "Undefined" if applicable.
The slope is ______ .
To find the slope between two points:
⇒ must know the slope's formula
[tex]\frac{y2-y1}{x2-x1}[/tex]
(x1, y1) --> any point on the line (x2, y2) --> any point on the line but (x1, y1)Let's consider the information given
⇒ given two points ⇒ (4, -6) and (-3,1)
Let's set: (you can interchange the two values of (x1,y1) and (x2,y2), it doesn't change the answer in any way)(x1, y) --> (4, -6)
(x2, y2) --> (-3, 1)

FIND THE RADIUS OF THE SHPERE WITH THE GIVEN VOLUME?
562.5π in.³
Answer:
Radius = 7.5 inStep-by-step explanation:
In the question we have given volume of Sphere that is 562.5 π in³ and we have asked to find the radius of given sphere. We know that the volume of sphere ,
[tex] \blue{ \boxed{ \rm{Volume \: of \: Sphere = \frac{4}{3} \pi r {}^{3} }}}[/tex]
So equating it with given volume for finding the radius of sphere :
[tex] \longmapsto \: \frac{4}{3} \pi r{}^{3} = 562.5\pi[/tex]
Step 1 : Cancelling π as it was present in both side :
[tex]\longmapsto\:\frac{4}{3} \cancel{\pi }r{}^{3} = 562.5 \cancel{\pi}[/tex]
Step 2 : Transposing 4/3 to right hand side :
[tex]\longmapsto \: r {}^{3} = 562.5 \times \frac{3}{4} [/tex]
Step 3 : Multiplying 562.5 with 3 :
[tex]\longmapsto \:r {}^{3} = \frac{1687.5}{4} [/tex]
Step 4 : Dividing 1687.5 by 4 :
[tex]\longmapsto \:r {}^{3} = 421.875[/tex]
Step 5 : Finding cube root of 421.875
[tex]\longmapsto \:r = \sqrt[3]{421.875} [/tex]
Step 6 : We get :
[tex]\longmapsto \: \red{ \boxed{r = 7.5}}[/tex]
Therefore , radius of sphere is 7.5 inches .#Keep LearningDistance between athe and moon written in scientific notation

a) The table is completed with 0.1.b) The team played 75 games.What is a proportion?A proportion is a fraction of a total amount.
Item a:
The sum of the frequencies is of 1, hence, the table is completed with 1 - (0.55 + 0.35) = 0.1.
Item b:
Considering that there were n games, we have that:
The team won 0.55n games.The team lost 0.35n games.The difference was of 15, hence:
0.55n - 0.35n = 15
0.2n = 15
n = 15/0.2

A teacher asks her class of 22 students, "What is your age?" Their responses are shown below.
19, 19, 14, 14, 16, 19, 19, 16, 16, 15, 17, 16, 17, 16, 15, 14, 15, 15, 17, 14, 16, 15
Find the mean, median, and mode for the data. If necessary, round to the nearest tenth.

OB. 16.1: 16; 16
C. 16.1; 17; 16
o
D. 16.5; 16; 17
Answer:
B.
Mean: 16.1
Median: 16
Mode: 16
Step-by-step explanation:
First, order the numbers in the data set from least to greatest:
[tex]14 , 14 , 14 , 14 , 15 , 15 , 15 , 15 , 15 , 16 , 16 , 16 , 16 , 16 , 16 , 17 , 17 , 17 , 19 , 19 , 19 , 19[/tex]
First, find the mean. The mean of a data set can be found by adding all the numbers together and dividing by the amount of numbers in the set:
[tex]\frac{14 + 14 + 14 + 14 + 15 + 15 + 15 + 15 + 15 + 16 + 16 + 16 + 16 + 16 + 16 + 17 + 17 + 17 + 19 + 19 + 19 + 19}{22} = \frac{354}{22}[/tex]
Next, simplify by dividing:
[tex]\frac{354}{22} = \frac{177}{11} = 16 \frac{1}{11} or ~16.1[/tex]
Mean: 16.1
Next, find the median. The median is the number(s) directly in the middle. If there is a even amount of number in the data set, find the mean of the two median numbers:
Median: 16 , 16
Median = [tex]\frac{16 + 16}{2} = \frac{32}{2} = 16[/tex]
Median = 16
Next, find the mode. The median is the number that shows up the most. In this case, it is 16, which appears 6 times, 1 more time then the next number that appears the most 15, which appears 5 times.
Mode: 16

Find the product of the following by writing one of numbers as the sum or difference of two numbers -
785*105
1006*95
3096*91
Answer:
Step-by-step explanation:
Use distributive property: a*(b+c) =a*b +a*c
1) 785 * 105 = 785 * (100 + 5)
= 785*100 + 785*5
= 78500 + 3925
= 82425
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2) 1006 * 95 = (1000 + 6) *95
= 1000*95 + 6*95
= 95000 + 570
= 95570
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3) 3096*91 = 3096 * (100 - 9)
= 3096*100 - 3096*9
= 309600 - 27864
= 281736
