Step-by-step explanation:
John said he can find 38×10 by adding a 0 to the end of 38 to get 380. John finds 46.52×10 using the same method and gets 46.520.
For the first one that is, 38 × 10 = 380, John is correct. For the second one, that is, 46.52 × 10 = 46.520. John is incorrect. In this case, the first one is correct because John was multiplying by a whole number.
For the second one involving a decimal, John could have shifted the decimal point one place to the right and not add 0 to the end. Then he will get:
46.52 × 10 = 465.2

Meaghan and Lily are dividing 43.61 by 7. Meaghan says that the first digit of the quotient is in the ones place. Lily says it is in the tens place. Who is right? How do you know?
Answer: Meaghan is right.
Step-by-step explanation:
For a number like:
123.45
the tens place would be the "2" (second number at the left of the decimal point)
The ones place would be the "3" (first number at the left of the decimal point)
Let's suppose that Lily is correct.
Then the quotient of:
43.61/7
Will be a number with two digits in the left of the decimal point.
The smallest number that meets this condition, is the number 10.
Then let's see:
7*10 = 70
then:
70/7 = 10
and:
43.61 < 70
(70 is larger than 43.61)
then:
43.61/7 < 70/7 = 10
Then:
(43.61/7) < 10
This means that our quotient is smaller than 10, then the first digit of the quotient can not be on the tens place.
Then Meaghan is the correct one.
We also could perform the quotient to find:
43.61/7 = 6.23
So yes, Meaghan is correct.

Answer:
[tex]\frac{3}{8}[/tex] feet²
Step-by-step explanation:
The area ( A) is calculated as
A = length × width
= [tex]\frac{3}{4}[/tex] × [tex]\frac{1}{2}[/tex] ← multiply numerators/ denominators
= [tex]\frac{3(1)}{4(2)}[/tex]
= [tex]\frac{3}{8}[/tex]

Answer:
The height of the hill is 131ft
See explanation in the photo
Answer:
91 feetStep-by-step explanation:
Refer to attached picture
Let the base is b and the height of the hill is x.
For the smaller triangle we have:
x/b = tan 39.3°And for the bigger triangle:
(x + 40)/b = tan 49.7°Solve both equations for b:
b = x/ tan 39.3°b = (x + 40)/tan 49.7°Eliminate b and get the values of tan, solve for x:
x/ tan 39.3° = (x + 40) / tan 49.7°x tan 49.7° = (x + 40) tan 39.3°x( 1.179) = x(0.819) + 40(0.819)x(1.179 - 0.819) = 32.76x = 32.76/0.36x = 91 feet (rounded to the nearest foot)Kyle ran the race in three and one hundred three thousandths seconds.

what can you tell about the mean of eachdistribution
Answer:
In a discrete probability distribution of a random variable X, the mean is equal to the sum over every possible value weighted by the probability of that value; that is, it is computed by taking the product of each possible value x of X and its probability p(x), and then adding all these products together, giving. .

four parcels had a weight of 400g. when a fifth parcel was added the mean became 500g. what was the weight of the fifth parcel?
Answer:
900 g
Step-by-step explanation:
Here, we want to get the weight of the 5th parcel
Mathematically, the total
is the mean multiplied by the count
the four parcel weighted 400 g averagely
The mean of this is 400(4) = 1,600 g
Adding the 5th parcel, we have an average of 500 g
This means that the total will be;
500(5) = 2,500 g
the difference in weight is the weight of the 5th parcel
That’s 2500-1600 = 900 g
How can you find the town with a temperature that is the opposite of -4°C? Name the town with that temperature
Answer:
Town B
Step-by-step explanation:
Given
See attachment
Required
Which town answers the question
From the attachment, the temperature of town J is -4°C.
This can be represented as:
[tex]J = -4^{\circ}C[/tex]
The opposite of -4 is 4.
So, the town with the temperature that is opposite of -4°C must have a temperature of 4°C.
From the attachment, the temperature of town B is 4°C.
This can be represented as:
[tex]B = 4^{\circ}C[/tex]
Hence, the answer to the question is town B

what is the reactants and products of Fe2O3+3CO→2Fe+3CO2
Step-by-step explanation:
The compounds that are found on the left of a chemical reaction (the side with the arrow's tail) are the reactants. Therefore our reactants are Iron(III) oxide and Carbon monoxide.

A basket contains 2 cartons of white milk, 3 cartons of chocolate milk, and 3 cartons of strawberry milk. A carton of milk is pulled out of the carton without replacement. Then another carton of milk is pulled out without replacement. What is the probability of pulling out 1 carton of chocolate milk followed by another carton of chocolate milk?
Answer: 3/8.
Step-by-step explanation: You have to write a fraction with the amounts of milk in the denominator and the amount of chocolate in the numerator.
Answer:
3/28Step-by-step explanation:
Total number of cartons:
2 + 3 + 3 = 8Let cm be the chocolate milk, there are 3 cartons of cm.
The probability of the first pull of cm is:
P(cm) = 3/8Then we have 7 total left and 2 cm.
The probability of the second cm is:
P(cm) = 2/7Now the probability of the two pulls:
P(cm and cm) = 3/8*2/7 = 3/28
