Answer:
Natalia's work is wrong.
Step-by-step explanation:
Natalia divided a decimal number by an entire number. Since division is a operation derived from multiplication, the best approach to check if work was good is multiplying the given result by denomination, that is:
1) [tex]x = 6.2\times 12[/tex] Given.
2) [tex]x = \left(6+0.2\right)\times 12[/tex] Definition of addition.
3) [tex]x = 6\times 12 + 0.2\times 12[/tex] Distributive property.
4) [tex]x = 72 + \frac{2}{10}\times 12[/tex] Definitions of multiplication and decimal number.
5) [tex]x = 72 +[2\cdot (10)^{-1}]\cdot 12[/tex] Definition of division/Associative property.
6) [tex]x = 72 + [2\cdot 12]\cdot (10)^{-1}[/tex] Associative property.
7) [tex]x = 72 + 24\cdot 10^{-1}[/tex] Definition of multiplication.
8) [tex]x = 72 + \frac{24}{10}[/tex] Definition of divsion.
9) [tex]x = 72 + 2.4[/tex] Defintion of decimal number.
10) [tex]x = 74.4[/tex] Definition of addition/Result
Natalia's work is wrong.

Answer:
He would drive 536 miles in 5 hours
Step-by-step explanation:
First set up your equation:
804 = 12x
Divide 804 by 12 and get 67 = x
Since per one hour you drive 67 miles, multiply 67 by 8 and get 536.
So, he drives 536 miles in 5 hours
Answer: I think 402
Step-by-step explanation: I divided 804 to 4 and I got 201 then I added 201+201= 402 and each 4 hours he went 201 miles so if you add 201 and 201 you get 402 miles. Hope it helped!! :)

Dexter runs around a track at 10 laps in 20 minutes. If he ran 32 laps at that rate, how long would it take him?
Answer:
64
Step-by-step explanation:
He will run 30 laps in 60 minutes because 10 times 3 and so if you divide 20 by 10 then he runs one lap in 2 minutes so 2 times 32 is 64 so it will take him that long

Solve for x using the
distributive property.
2(x - 5) = 10
Answer:
x=10
Step-by-step explanation:
2x-10=10
2x=20
x=10
Answer:
x=10
Step-by-step explanation:
2(x - 5) = 10
You would first multiply 2 by x and 5
2x-10 = 10
then you would add ten to both sides
2= 20
then you would divide 2 by 20
x=10

What is the fifth term of the geometric sequence whose first three terms are 486, 162, and 54?
a. 2
b. 3
c. 4.5
d. 6
e. 9
Answer:
6
Step-by-step explanation:
an = ar^(n-1)
a = first term
n = nth term
r = common ratio
r = r2 / r1 = r3 / r2
The first 3 terms are :
486, 162, and 54
Hence,
a = 486
r = 162 / 486 = 1/3
Hence ;
a5 = 486(1/3)^5 - 1
a5 = 486(1/3)^4
a5 = 486(1 / 81)
a5 = 486 * 1 / 81
a5 = 486 / 81
a5 = 6
The 5th term of the geometric progression will be ; 6

Answer: C
Step-by-step explanation:
1.25 + (- 0.75) is equal to 1.25 - 0.75.
1.25 is positive while - 0.75 is negative. So 1.25 is head toward the right while - 0.75 is head toward the left.
And when you substract them, you will get 0.5.
So the answer is C.

Luke went to a blackjack table at the casino. At the table, the dealer has just shuffled a standard deck of 52 cards.
Luke has had good luck at blackjack in the past, and he actually got three blackjacks with Queens in a row the last time he played. Because of this lucky run, Luke thinks that Queens are the luckiest card.
The dealer deals the first card to him. In a split second, he can see that it is a face card, but he is unsure if it is a Queen.
What is the probability of the card being a Queen, given that it is a face card? Answer choices are in a percentage format, rounded to the nearest whole number.
a) 8%
b) 4%
c) 33%
d) 77%
Answer:
c) 33%
Step-by-step explanation:
In a standard deck of cards, there are 52 cards total and of those 52, there are 12 face cards. One-third of those face cards are queens, (because there are 4 queens in a deck of cards, and [tex]\frac{4}{12}=\frac{1}{3}[/tex]). Therefore, there is a 33% chance that the card Luke holds is a queen.
Answer:
33%
Step-by-step explanation:

Which statement explains why △ABC is congruent to △A′B′C′?
a)You can map △ABC onto △A′B′C′ by reflecting it over the y-axis and translating it 4 units down, which is a sequence of rigid motions.
b)You can map △ABC onto △A′B′C′ by reflecting it over the x-axis and translating it 7 units right, which is a sequence of rigid motions.
c) You can map △ABC onto △A′B′C′ by rotating it 90° clockwise about the origin and translating it 5 units right, which is a sequence of rigid motions.
d)You can map △ABC onto △A′B′C′ by reflecting it over line y = x and translating it 5 units right, which is a sequence of rigid motions.
Answer: B
Step-by-step explanation:
Find the PERCENT of Change.
The original cost was $50 and the new cost is $200.
Answer:
300%
Step-by-step explanation:
To find percent change we need to use this formula:
[tex]change = \frac{Amount of change}{Original} * 100[/tex]
To find the amount of change we need to minus 50 from 200:
200 - 50 = 150
Now that we have the amount of change we can plug it in to the equation with the original amount (50):
[tex]change = \frac{150}{50} = 3 * 100 = 300[/tex]
Therefore, the percent of change is 300%.
I hope this helps!!

A bag contains 2 red marbles, 3 green marbles, and 4 blue marbles.
If we choose a marble, then another marble without putting the first one back in the blag, what is the
probability that the first marble will be green and the second will be red?
Answer:
number of green ÷ total number of marbles
times by
number of red ÷ total number of marbles left
so
(3/9) × (2/8) = (1/12)
A dragon is given 630 ounces of magical potion to sustain her journey from Arlandia to Gargandua. While flying 4/7 of the distance, she drinks 2/9 of the potion. Suppose she continues to drink the magical potion at this rate for the remainder of her journey. How much potion remains when she reaches Gargandua?
Can someone help me with this question? I can't even start!
P.S. Answering this question will give you the highest credit!
Step-by-step explanation:
4/7 of distance = 2/9 of potion
=> 7/7 of distance = 2/9 * (7/4) = 7/18 of potion.
The dragon has used 7/18 of the potion for the journey, and only have 11/18 of it left.
Amount left = 630 ounces * 11/18 = 385 ounces.

(3,4);m=-z in point slope formula
Given:
Point = (3,4)
Slope : m = -z
To find:
The point slope formula.
Solution:
Point slope form: If a line passes through the point [tex](x_1,y_1)[/tex] and having slope m, then the point slope form of the line is
[tex]y-y_1=m(x-x_1)[/tex]
The line passing through the point (3,4) and having slope -z.
Putting [tex]x_1=3,y_1=4, m=-z[/tex], we get
[tex]y-4=-z(x-3)[/tex]
Therefore, the required point slope form is [tex]y-4=-z(x-3)[/tex].
