How many times larger is 4x10^7 than 5x10^5

irina1246 [14]

Answer:

8 times larger

Step-by-step explanation:

4 · $10^{7}$ = 4 · 10 · 10 · <u>10</u> · <u>10</u> · <em>10</em> · <em>10</em> · 10

4 · 100 · <u>100</u> · <em>100</em> · 10

400 · 10000 · 10

= 40000000

5 · $10^{5}$ = 5 · 10 · 10 · <u>10</u> · <u>10</u> · 10

50 · 100 · <u>100</u> · 10

5000 · 1000

= 5000000

40000000 ÷ 5000000 = 8

5/8 of an inch in percent

Dovator [93]

<h2>Greetings!</h2>

Answer:

62.5%

Step-by-step explanation:

To find the percentage, you simply need to divide the number on top by the number on bottom and multiply by 100:

5 ÷ 8 = 0.625

0.625 x 100 = 62.5

So the percentage is 62.5%!

Delia is bagging 24 onion bagels and 16 plain bagels for her bakery customers. Each bag will hold only 1 type of bagel. Each bag

Mnenie [13.5K]

<h2>Answer:</h2><h2>8 bagels in each bag, 3 bags of onion, 2 bags of plain</h2>

24 onion bagel

16 normal bagel

We need the GCF (Greatest Common Factor) of 16 and 24 to find the answer.

Factors of 16 = 1, 2, 4, 8, 16

Factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24

What is the GCF? It is 8.

Hence, 8 bagels in each bag.

24/8 = 3 bags of onion bagels

and

16/8 = 2 bags of plain bagels

I need help with this problem

Irina-Kira [14]

Answer:

3695.5 m

1530.73 m

Step-by-step explanation:

Given in the question,

The distance probe travels at an angle of depression 67.4 from the ship to the ocean surface = 4000m

We will use trigonometry identities

<h3>sinФ = opposite / hypotenuse</h3><h3>cosФ = adjacent/ hypotenuse</h3>

distance of probe from top of sea to surface = x

cos(90 - 67.5) = x / 4000

x = 3695.5 m

horizontal distance from ship to probe = y

sin(90-67.5) = y / 4000

y = 1530.73 m
