The part with crosses covers two little blocks.
So its area is (2 x 1/4) = 1/2 .

kenny has 9 more comic books than bobbie. together they have 95 comic books. define a variable. then write an equation that could be used to find the number of comic books they each have.

Answers

Number of comic books Bobbie has - b

95 = (9 + b) + b

Since 95 is the total number of comic books both boys have, it is equal to both boys' books added together. However, since we don't know how many books Kenny has, and only that he has 9 more than Bobbie, we can define that as (9 + b), or nine more than b. Then, we add b again, because (9 + b) is the number of books Kenny has, and if we add that to the number of books Bobbie has, it will equal the total of 95 comic books.

A jacket is discounted 30% off. The original was $150.00. What is the new price of the jacket after the discount?

Answers

$105. 30% of 100 is 30 and 30% of 200 is 60 it'd be 45 off because it's the number between the 2. Leaving 150-45=$105

$50. So, first we have to take the original price and divide it. $150.00 divided by 3 equals $50.

I believe the answer is $48 because 6 * 2 is 12 and 12 * 2 is 24 and 24 * 2 is 48, thus 48$. Please feel free to check my work, though.

How many days are in 7.5 years

Answers

In one year, there is 365 days, and every 4th year it's 366.
in 7.5 years there is only one 4 year, so 1 year with 366 years.

1 year = 365 days
7.5 years = x days

x = 7.5 * 365
x = 2737.5 days
and since we have a leap year of 366 days, we get
2737.5 + 1 = 2738.5

So, there is 2738.5 days in 7.5 years

Hope this Helps :)

You can't use calendars to answer this.

We put different numbers of days in different calendars, to account for the
fraction of a day in the Earth's trip around the sun. So if you used calendars
to answer the question, the answer would depend on what year, or what part
of a year, you start counting in. There could be either one or two Leap years
in the period you choose.

The only honest and effective way to calculate the answer is to take the word "year"
to mean the real length of the Earth's orbital trip.

The length of the Earth's sidereal year is 365.2536 mean solar days. (rounded)

No matter what year you start counting, or what part of what day of what year,
in 7.5 sidereal years you'll count 2,739 mean solar days, and then the count will
end roughly another 9 hours and 38 minutes later.
