A few tips:

  • If the numbers are in negatives, the greatest number should be the closest from 0.
  • If the numbers are in positives, the greatest number should be farthest from 0
  • If the numbers are in positives and negatives, the number which is farthest from 0 will be the greatest.

Solution (Verification for Option A):

  • -3, -4, -7, -8, -9

<u>In this case, all the numbers are in negatives.</u>

  • => -3 > -4 > -7 > -8 > -9 (Correct)

Solution (Verification for Option B):

  • 9, 7, 6, -5, -4

<u>In this case, a few numbers are in positives and in negatives.</u>

  • => 9 > 7 > 6 > -5 > 4 (Incorrect)

Solution (Verification for Option C):

  • 8, -6, 5, -4, 1

<u>In this case, a few numbers are in positives and in negatives.</u>

  • => 8 > -6 > 5 > -4 > 1 (Incorrect)

Solution (Verification for Option D):

  • -3, -1, 0, 2, 7

<u>In this case, a few numbers are in positives and in negatives.</u>

  • => -3 > -1 > 0 > 2 > 7 (Incorrect)

Conclusion:

  • Option A is correct.

A) Scale of map is 1: 30,000

This is assuming that it meant 1 centimetre = 30,000 metres, for it gives no other information.

Multiply 1 with 30,000: 30,000 x `1 = 30,000

30,000 metres is your answer.

B) Scale is 1 inch: 6 miles. You are given 2.5 inches.

Remember that 1 inch = 6 miles.

Multiply 2.5 to both sides: (2.5) * 1 inch = (2.5) * 6 miles

2.5 inch = 2.5 * 6 miles

2.5 inch = 15 miles

15 miles is your answer.

Marysya12 [62]

9514 1404 393

Answer:

  • length: 29 ft
  • width: 20 ft

Step-by-step explanation:

Assuming the dimensions are integer numbers of feet, you're looking for factors of 580 that have a difference of 9.

 580 = 1×580 = 2×290 = 4×145 = 5×116 = 10×58 = 20×29

The last pair of factors differs by 9, so ...

  the length is 29 feet; the width is 20 feet.

If Sarah invests $5,000 into a fund that earns 6% interest compounded annually, how long will it take for her investment to grow
yarga [219]

Answer:

40

Step-by-step explanation:

so next year her money would be 6% more so:

5000 + (0.6 * 5000) = (1.06) * 5000

So each year she'll have : (1.06)*(last year's money)

So we can say after n years she will have :

((1.06)^n) * 5000

So:

5000((1.06)^n)=50000

n is 39.5

So around 40

Simora [160]

Option A) 14/250 = N/350 is correct.

Kevin wants to change the engine in her car. The current engine is 250 cubic centimeters and has a 14 inch fan belt. The new engine is 350 cubic centimeters and has proportionally larger fan belt.

<h3>What is proportionality?</h3>

proportionality can be defined as, how much the number is relatable to other number i.e. x =2y x is two times proportion to y.

Hence, in the question
for 250 cc engine it has 14 inch belt
for 350 cc engine it has N inch belt(let)
proportionality can be given as
14 ∝ 250
N ∝ 350
dividing both equation
N/14=350/250
or 14/250=N/350

Thus, the required proportion is given as 14/250=N/350.
