Answer:
Step-by-step explanation:
Given question is incomplete; here is the complete question,
Here is an equation that represents a function: 72x + 12y = 60.
Select all the different equations that describe the same function.
A). 120y + 720x = 600
B). y = 5 - 6x
C). 2y + 12x = 10
D). y = 5 + 6x
E). [tex]x=\frac{5}{6}-\frac{1}{6}y[/tex]
F). 7x + 2y = 6
G). [tex]x=\frac{5}{6}+\frac{y}{6}[/tex]
Option A.
720x + 120y = 600
[tex]\frac{1}{10}(720x+120y)=\frac{1}{10}(600)[/tex]
72x + 12y = 60
True.
Option B.
y = 5 - 6x
6x + y = 5
12(6x + y) = 12(5)
72x + 12y = 60
True
Option C.
2y = 12x + 10
-12x + 2y = 10
-6(-12x + 2y) = -6(10)
72x - 12y = -60
False
Option D.
y = 5 + 6x
-6x + y = 5
-12(-6x + y) = -12(5)
72x - 12y = -60
False.
Option E.
[tex]x=\frac{5}{6}-\frac{1}{6}y[/tex]
[tex]72x=72(\frac{5}{6}-\frac{1}{6}y)[/tex]
72x = 60 - 12y
72x + 12y = 60
True.
Option F.
7x + 2y = 6
6(7x + 2y) = 6(6)
42x + 12y = 36
False
Option G
[tex]x=\frac{5}{6}+\frac{1}{6}y[/tex]
[tex]72x=72(\frac{5}{6}+\frac{1}{6}y)[/tex]
72x = 60 + 12y
72x - 12y = 60
False
Options A, B and E are the correct options.
How many zeroes are at the end of $42!$ (42 factorial)? (Reminder: The number $n!$ is the product of the integers from 1 to $n$. For example, $5!=5\cdot 4\cdot3\cdot2\cdot 1= 120$.)
Answer:
47 zeros

Think About the Process Which property of exponents do you use to simplify this expression? Simplify the expression. 12^8/12^4
Answer:
12^4 = 20736
Step-by-step explanation:
The property of exponents used to simplify : 12^8/12^4
The division property :
a^x / a^y = a^(x - y)
Therefore ;
12^8/12^4
12^8 / 12^4 = 12^(8 - 4) = 12^4 = 20,736

Clare said that 4/3 divided by 5/2 is 10/3 She reasoned: 4/3 x 5 equals 20/3 and 20/3 divided by 2 is 10/3 Explain why Clare's answer and reasoning are incorrect. Find the correct quotient.
Answer: See explanation
Step-by-step explanation:
4/3 ÷ 5/2
To solve this further, the minus sign changes to multiplication and the inverse of 5/2 is written. This will be:
= 4/3 ÷ 5/2
= 4/3 × 2/5
= 8/15
Claire's reasoning is wrong as she didn't multiply by the inverse of the number.

Question
224 7/10 as decimal
Answer:
224 7/10 is a mixed fraction ..so first we convert it into an improper fraction ...
=> for that follow these steps ...
=> 224 X 10 + 7
=> 2247/10
so now to get in decimals ..we divide 2247 by 10..
=> 224.7 ...
so here we got 224 7/10 in its decimal form ...
Step-by-step explanation:
hope that helps :))
Answer:
0.7 or 244.7
Step-by-step explanation:
I don't know if the question number is 224 and you're trying to write 7/10 as a decimal or if the number you're trying to write as a decimal is 224 7/10.
If the number is 7/10 then the decimal form would be 0.7
If the number is 244 7/10 then the decimal form would be 244.7

if you stop at random in front of an animal exhibit,What is the probability that you will be looking at monkeys? I put the table chart below
Answer:
1/10
step-by-step explanation:
----------------------------------
| animals | percent of animals |
----------------------------------
| goats | 16% |
----------------------------------
| camels | 4% |
----------------------------------
| giraffes | 6% |
----------------------------------
| llamas | 6% |
----------------------------------
| deer | 1% |
----------------------------------
| monkeys | 10% |
----------------------------------
| birds | 27% |
----------------------------------
| reptiles | 14% |
----------------------------------
| bears | 16% |
----------------------------------
( sorry if the table above isnt 100% right or straight ^ )
first you add up all the percents of how much animals are in this exhibit
16 + 4 + 6 + 6 + 1 + 10 + 27 + 14 + 16
= 100 %
then since we are looking for the probability of stopping in front of the monkeys, we take that 100 we got earlier and get the 10% of monkeys from our table
10/100
but since there isnt a 10/100 on the answers we look for something that equals to 10/100 and 1/10 does since you can just times both the 1 and 10 to equal the 10 and 100 you were looking for
1/10
making 1/10 your answer!
hope this helps! and if you need anymore help on this math question just ask me :)

The arc from A to B not passing through C measures 50 degrees. Select all the true statements.
Angle BCA measures 50 degrees.
Angle BCA measures 25 degrees.
Angle BOA measures 50 degrees.
The arc from B to C not passing through A
measures 180 degrees.
Angles CBO and CAO are congruent
Applying the inscribed angle theorems, the true statements regarding the given diagram are: B. m∠BCA = 25° C. m∠BOA = 50°
What is the Inscribed Angle Theorems?The inscribed angle theorems state that:
Measure of intercepted arc = 1/2(measure of inscribed angle)Measure of intercepted arc = measure of central angle.∠BCA is an inscribed angle.
m(AB) is the intercepted arc = 50°
∠BOA is the central angle
m∠BCA = 1/2(m(AB) = 1/2(50) = 25°
m∠BOA = m(AB) = 50°
The true statements are:
m∠BCA = 25°
m∠BOA = 50°

Find the surface area
Find the difference. (3a - 6b +12)- (6a - 2b+ 7). Show all steps.
PLEAS HELP ITS FOR A TEST
-3a-4b+5
(3a - 6b +12)- (6a - 2b+ 7).
step 1: remove parentheses and change 2b +7 to 2b -7 and 6a -2b to 6a +2b
3a - 6b +12- 6a + 2b- 7
-3a-4b+5
step 2: from 3a - 6b +12- 6a +2b- 7
subtract: 3a - 6a= -3a.
now its -3a - 6b + 12 - 6a + 2b - 7
then 6b - 2= 4
now is -3a - 4b + 12 - 7
then 12 - 7 =5
Answer: -3a-4b+5
