Answer:

Nearest ten-350

Nearest hundred-300

Step-by-step explanation:

#When rounding to the nearest ten, we look at the ones digits in a number:

  • If the ones digit  is 0, 1, 2, 3, or 4, you will round down to the previous ten
  • If the ones digit is 5, 6, 7, 8, or 9, you will round up to the next ten

Given the number 348, 8 in the ones digit greater than 4 so we round to the next ten:

                    348 ≈350

#When rounding to the nearest hundred, we look at the tens digits in a number:

  • If the ones digit  is less than 5 you will round down to the previous hundred
  • If the ones digit is greater than 4, you will round up to the next hundred

Given the number 348, 4 in the tens digit less than 5 so we round down to the previous hundred:

                       348 ≈300

Which of these is true<br> a: 0.7 &gt; 3/5 <br> b: 0.7 &lt; 3/5 <br> c: 0.7 = 3/5
omeli [17]
The answer is A. When 0.7 is put into fraction form it turns into 7/10. Then change the denominator of 3/5 to 10 which makes it 6/10. 7/10 is higher than 6/10 so the answer is A.

kow [346]

Answer:

  C.  7 hours

Step-by-step explanation:

Let the time for the trip out be represented by t. Then the time for the return trip is t-1. The distance was the same for both trips, so we have ...

  distance = speed × time

  300t = 350(t -1)

  300t = 350t -350 . . . . eliminate parentheses

  350 = 50t . . . . . . . . . . add 350-300t

  7 = t . . . . . . divide by 50

The trip out took 7 hours.

Find the values of the pronumerals in this diagram. Write down the reason in each case.
timofeeve [1]

Answer:

see explanation

Step-by-step explanation:

a and 85 form a straight angle and are supplementary, thus

a + 85 = 180 ( subtract 85 from both sides )

a = 95

b and 85 are vertical angles and are congruent, thus

b = 85

c and 85 are corresponding angles and congruent, thus

c = 85

c and d are vertical angles and congruent, thus

d = 85

In conclusion

a = 95, b = 85, c = 85, d = 85
