First, simplify each one.

9.98 x 10^6 = 9980000

7.3 x 10^7 = 73000000

Next, subtract the freight from the aircraft

73000000 - 9980000 = 63020000

Round the decimal point to the first significant digit, and place the amount of place values the decimal point moved to the left as a power sign, over 10.

63020000 = 6.302 x 10^7

6.302 x 10^7 is your answer

hope this helps

Solution:

Freight Train:

= 9.98 x 10^6

= 9.98 x (10 x 10 x 10 x 10 x 10 x 10)

= 9.98 x (1,000,000)

= 9,980,000 kilograms

Aircraft Carrier:

= 7.3 x 10^7

= 7.3 x (10 x 10 x 10 x 10 x 10 x 10 x 10)

= 7.3 x (10,000,000)

= 73,000,000 Kilograms

The aircraft carrier is 72,020,000 kilograms more than the freight train!

0.0000007202 = 7.202 x 10^-7

What is the square of one half?
Vlad1618 [11]

Answer:

One-half squared is one-fourth.

Step-by-step explanation:

When you divide fractions, you multiply the first term by the reciprocal of the second term. In this example, instead of multiplying 1/2 by 1/4, you now multiply 1/2 by 4. Therefore, one half is equal to 2 fourths.

a cone with radius of 3 feet and a height of 5 feet is placed on top of a cylinder as shown find the volume of the total figure
Darina [25.2K]

Answer: Volume of the cone = 47.12 cubic feet.

Step-by-step explanation:

You didn't finish the question so Idid the best with what I had, you also didn't include the image that I think was supposed to be included.

To solve for the full volume including the cylinder, use the cylinder's volume formula.

Volume of a cylinder = height (pi) (r^2) and then add it to the 47.12.

Volume of a cone is pi(r^2)(h/3)

plug and chug!

h stands for height and r stands for radius.

What is the effect on the graph of the function f(x) = x when f(x) is replaced with −f(x) + 5?
prohojiy [21]

Answer:

The function f(x) translated left by 5 units and then it is reflected across the x-axis.

Step-by-step explanation:

The original equation of the graph of the function is f(x) = x ........ (1)

If we replace f(x) by [- f(x) + 5] then the equation becomes - f(x) + 5 = x  

⇒ f(x) = - (x - 5) ..... (2)

So, comparing equations (1) and (2), we can conclude that the graph of the function f(x) translated left by 5 units and then it is reflected across the x-axis. (Answer)

HELP ASAP plz I’ll give brainliest and plz explain:)
yaroslaw [1]

Answer: No, Store A is charging $2.20 per rose while Store B is charging 2.166667 dollars per rose.

Step-by-step explanation:

11/5 = 2.2

(To check) 2.2 x 5 also equals $11

However, they are not selling roses at the same rate because if you were to do 2.2x6 it will equal 13.2.

13/6 = 2.166667

****PLEASE HELP**** Meghan spends 25% more each year for auto insurance than Scott, and together they spend $1237.50 per year. H
s344n2d4d5 [400]

Answer: Meghan spent $687.5 per year.

Step-by-step explanation:

Let x represent the amount of money that Scott spends per year for auto insurance.

Meghan spends 25% more each year for auto insurance than Scott. The value of 25% of the amount that Scott spends per year is

25/100 × x = 0.25 × x = 0.25x

Therefore, the amount that Meghan spends would be

x + 0.25x = 1.25x

If the amount that they spent together is $1237.50 per year, it means that

x + 1.25x = 1237.5

2.25x = 1237.5

x = 1237.5/2.25

x = 550

The amount that Meghan spent per year would be

1.25 × 550 = 687.5
