Answer:
g=1.25
Step-by-step explanation:
Divide 4 into 3.2
4/3.2=1.25
Try to use inverse operations to solve this problem.
First multiply both sides by g to get the g out from under the 4 The equation is now:
4=3.2g
From here then you divide both sides by 3.2.
The answer is g=1.25

The loudness, L. measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as
L - 10log , where lo - 10- and is the least intense sound a human ear can hear. Jessica is listening to soft music at a
sound intensity level of 109 on her computer while she does her homework. Braylee is completing her homework while
listening to very loud music at a sound intensity level of 10 on her headphones. How many times louder is Braylee's music
than Jessica's?
Answer:
Option A is correct.
Braylee's music is 3 times louder than Jessica's.
Step-by-step explanation:
Full Complete Questions
The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as
L = 10log (I/I₀), where lo = 10⁻¹² W/m²
and is the least intense sound a human ear can hear.
Jessica is listening to soft music at a sound intensity level of 10⁻⁹ W/m² on her computer while she does her homework.
Braylee is completing her homework while listening to very loud music at a sound intensity level of 10⁻³ W/m² on her headphones. How many times louder is Braylee’s music than Jessica’s?
times louder
3 times louder
30 times louder
90 times louder
Solution
The loudness of a sound intensity is given as
L = 10 log (I/I₀)
For Jessica
I = 10⁻⁹ W/m²
I₀ = 10⁻¹² W/m²
L = 10 log (10⁻⁹/10⁻¹²)
L = 10 log (10³)
L = 10 × 3 = 30 dB
For Braylee
I = 10⁻³ W/m²
I₀ = 10⁻¹² W/m²
L = 10 log (10⁻³/10⁻¹²)
L = 10 log (10⁹)
L = 10 × 9 = 90 dB
How many times louder is Braylee's music than Jessica's?
The factor by which Braylee's music is louder than Jessica's = (90/30) = 3
Braylee's music is 3 times louder than Jessica's.

Answer:
0.02 repeating
Step-by-step explanation:
So first we do 2/9 since all the operations are division we solve left to right. We get 0.2 repeating. Then, after that whenever we divide by 10, we shift everything to the right so we end up with :
0.02 repeating.
What is the measure of \angle DEG∠DEGangle, D, E, G on circle OOO?
^\circ

Answer:
50°
Step-by-step explanation:
In the figure attached, the plot of the problem is shown.
Assuming that segments DE and CF are parallel then the following angles are congruent:
∠DEG ≅ ∠CFG
∠CGF ≅ ∠DGE
∠GCF ≅ ∠GDE
As a consequence, ∠DEG = 50°

Answer:
x=20 and y=128.Option 2
Step-by-step explanation:
Since,the angles are vertically opposite,they are equal(property)
Therefore,
(3x-8)=(2x+12)
3x-8=2x+12
3x-2x=12+8
x=20,
Now,
Since,the angles are formed in a straight line,their sum is equal to 180(property)
Therefore,
y+(2x+12)=180
y+2×20=180-12
y=168-40
y=128
Therefore,x=20 and y=128
option 2 would be your answer because it explains the missing part where y is.
Find the surface area of the figure. Round the the nearest hundredth.
Answer:
Step-by-step explanation:
surface area of cylinder=2πrh
SA=1/2×2×π×3×25+2 ×(1/2×π×3²)=75π+9π=84π≈84×3.14≈263.76 cm²
if lowerside is also counted then area of lower side=25×6=150
total surface area=263.76+150=413.76 cm²
if we take π=22/7
84 π=84×22/7=12×22=264 cm²
if base is also counted then area=264+150=414 cm²

elijah's credit card statement showed these items: Last Balance Payments Finance Rate New Charges $152.58 $45.00 1.5% $213.40 What is Elijah's new balance? $320.98 $322.59 $323.27 $397.51
Answer:
Option A,$320.98 is correct
Step-by-step explanation:
The new balance on Elijah's credit is the sum of the last balance plus new charges minus payments made.
last balance as shown by the statement was $152.58
new charges were $213.40
payment made by Elijah was $45
new balance=$152.58+$213.40-$45=$320.98
The rationale for this is that the new charges on the card account add to previous balance owed by Elijah while the payment of $45 made reduces overall balance.
Answer:
Other answer is incorrect. Elijah's new balance would be $322.59
Your welcome.

Jaira is having pizza for her birthday party. She can make two small pizzas, each with a radius of 6 inches, or one large pizza with a radius of 12 inches. Which option will give her more square inches of pizza?
Answer: One large pizza with a radius of 12 inches
Step-by-step explanation:
Hi, to answer this question we have to calculate the area of each option.
Area of a circle: π r^2
Option 1: two small pizzas, each with a radius of 6 inches.A = π r^2 = π 6^2 = 113.1 in2
Since there are 2 small pizzas we have to multiply the area by 2:
113.2 x 2 = 226.2 in2
Option2 = one large pizza with a radius of 12 inchesA = π r^2 = π 12^2 = 452.38 in2
Since 452.38 in2 > 113.1 in2
Option 2 (one large pizza) will give her more square inches of pizza

Which two terms are interchangeable
Answer:
C hope this helped :D if not plz let me know..
The terms that are interchangeable are axioms and postulates.
What are Axioms and Postulates ?"In mathematics or logic, an axiom is an unprovable rule or first principle accepted as true because it is self-evident or particularly useful. “Nothing can both be and not be at the same time and in the same respect” is an example of an axiom"
"The term is often used interchangeably with postulate, though the latter term is sometimes reserved for mathematical applications (such as the postulates of Euclidean geometry). It should be contrasted with a theorem, which requires a rigorous proof."
By the definition of Axiom and postulates,
It is clear that Axiom and postulates are interchangeable, since they both used as a unprovable rule.
Hence A is the correct option.

For the data set 6, 5, 10, 11, 13, the mean, X, is 9. What is the standard
deviation?
Answer:
standard deviation = 3.0331
Step-by-step explanation:
You can solve for this two different ways.
If you have a TI-84 calculator or something similar, type all the data into list 1. Then click the stat button, then the calc button, then 1-vars stats. This will give you mean, standard deviation, median, mode, etc.
If you are solving by hand, find the different between each data point and the mean. Square these numbers and find the average. Then take the square root of that.
3^2 + 4^2 + 1^2 + 2^2 + 4^2 = 46
46/5 = 9.2
square root of 9.2 = 3.0331

Using multiplication, the original number is 7.
What is multiplication?Multiplication is "the process multiplying that the integer is multiplied by number of time".
According to the question,
A number is multiplied by 4. The results is added to 12. The final number is 40. In order to find original number.
4x + 12 = 40
4x = 40 -12
