Answers

Answer 1

Answer:

Answer:

1) 170,000

2) 446,220

3) 50,000

4) 7,800

Step-by-step explanation:

When we round a number to the nearest hundred then we check the digit at tens place,

If the digit is less than 5 then the number is rounded to previous thousand and if it is 5 more than 5 it is rounded to the next thousand,

While, in the case of rounding nearest ten and ten thousand we check the digit at ones place and thousand placerespectively.

1)168,356 to the nearest ten thousand is 170,000 ( ∵ thousand place digit = 8 > 5 )

2) 446,221 to the nearest ten is 446,220 ( ∵ ones place digit = 1 < 5 )

3) 45,122 to the nearest ten thousand is 50,000 ( ∵ thousand place digit = 5 ≥ 5 )

4) 7,782 to the nearest hundred is 7,800 ( ∵ tens place digit = 8 > 5 )

Answer: 1)170,000
2)446,220

on average a baby uses 3 times the number of large diapers as small diapers and double the number of medium diapers as small diapers. If the average baby uses 2940 diapers size large and small, how many of each size would be used

Answers

Okay, if I read this correctly, then the number of large diapers is three times as many as small, and the medium diapers are two times as many as small. To set this equation up, assign x as the unknown value. Small = x Medium = 2x and Large = 3x . Add all of these together and equal them to 2940. From here, solve the equation (6x=2940) by dividing the entire thing by 6. You will have x = 490.
To find the number of each size, plug it back into the original.
Large: 3x = 3(490) = 1470
Medium: 2x = 2(490) = 980
Small: x = 490
Hopefully I read the problem correctly.

Evan’s family drove to a theme park for vacation. Assume they drove the same speed throughout the trip. The first day, they drove 300 miles in 6 hours. The second day, they drove 250 miles in 5 hours. The third day, they arrived at the park by driving ________ miles in 3 hours.A. 30
B. 125
C.150
D.100

Answers

In the given problem the best hint that is given for getting to the answer is that Evan's family drove at the same speed each day.
Then
On the first day the speed of the car = Distance/time
   = 300/6
   = 50 miles/hour
Then for calculating the distance traveled on the third day = speed * time
   = 50 * 3
   = 150 miles
Then on the third day they arrived at the park by driving 150 miles in 3 hours. So the correct option is option "C".

300÷6 is 50 so they travel 50 miles per hour. that means, in 3 hours they can travel 150 miles so the answer is C

X+19=13

Find the value of x.

Answers

to find the value of x we need to use the INVERSE OPERATION of addition which is subtraction. Then we will check our work. lets do it:-

x + 19 = 13
x = ?
13 - 19 = x
13 - 19 = -6
x = - 6

CHECK OUR WORK:-

x + 19 = 13
x = -6
-6 + 19 = 13
We were RIGHT!!

So, x = -6

Len walks 3/10 mile in the morning and 2/5 mile in the afternoon len says that he walks a total of 5/15 mile in the morning and afternoon

Answers

Hey There!

Steps to solve (Please note, steps will be in numerical order.)

1.To start off you have to find the lCD of $(3)/(10)$ and $(2)/(5)$ . So, the LCD of both fractions is ten.

2. Now, rewrite the fraction $(3)/(10)$ to $(4)/(10)$ , since the lcd is 10 you have to multiply the numerator and denominator of $(2)/(5)$ by two.

3. You only have to add $(3)/(10)$ + $(4)/(10)$

4. First, add the numerators 3+4 which is 7. Remember when adding fractions the denominator stays the same.

5. In conclusion, you're final answer should be $(7)/(10)$ , so Len's statement was false and he walked total $(7)/(10)$ steps.

Hope This Helped :)
