Xan and Katie are twins. Xan weighs 66 6 6 pounds 99 9 9 ounces, and Katie weighs 88 8 8 pounds 11 1 1 ounce. What is the differ

gtnhenbr [62]

Answer:

264 ounces

Step-by-step explanation:

#Convert Xan weight into ounces:

$1lb= 16 \ oz\\\\66\ lb=66\times 16=1056 \ oz\\\\\therefore Xan's=1056 \ oz+ 99 \ oz=1155 \ oz$

Convert Katie's 88 pounds 11 ounce to ounces:

$1lb= 16 \ oz\\\\88\ lb=88\times 16=1056 \ oz\\\\\therefore Katie's=1408 \ oz+ 11 \ oz=1419\ oz$

The difference is calculated by subtracting Xan's from Katie's:

$=1419 \ oz-1155 \ oz\\\\=264\ oz$

Hence, the difference between the weights is 264 ounces

The sum of 4 times a number and 15 is 47. Find the number.

Bezzdna [24]

Answer:

The number is 8.

Step-by-step explanation:

Write an equation then solve by isolating the variable.

let x be the number

4x + 15 = 47 Subtract 15 from both sides

4x = 47 - 15

4x = 32 Divide both sides by 4

x = 32/4

x = 8

Therefore the number is 8.

From class we learned that in 2010 the federal debt (in millions) was $13,561,623 and the population of the U.S. was 309 million

ELEN [110]

Net Debt per Capita=(Short Term Debt+Long Term Debt-Cash and Cash Equivalents)/Population
From the information given:
federal debt in 2010 (in millions)=$13,561,623
Cash and cash equivalents=0
population=309 million
Hence the federal debt per capita will be:
(13,561,623)/(309)
=$43,888.75
