The average weight of a basketball is 21 1/8 ounces. The average weight of a baseball is 5 2/8 ounces. How many more ounces does the basketball weigh?

Answers

Answer 1

Answer:

Answer:

$15(7)/(8)\ ounces$

Step-by-step explanation:

step 1

Convert mixed number to an improper fraction

$21(1)/(8)\ ounces=21+(1)/(8)=(169)/(8)\ ounces$

$5(2)/(8)\ ounces=5+(2)/(8)=(42)/(8)\ ounces$

step 2

To find out how many more ounces does the basketball weigh, subtract the weight of a baseball from the weight f a basketball

$(169)/(8)\ ounces-(42)/(8)\ ounces=(127)/(8)\ ounces$

Convert to mixed number

$(127)/(8)\ ounces=(120)/(8)+(7)/(8)=15(7)/(8)\ ounces$

Answer 2

Answer:

Answer:

$15(7)/(8) \ ounces$

Step-by-step explanation:

The questions tests for subtraction of fractions.

Start by converting the two fractions into improper numbers:

$21(1)/(8)=(169)/(8)\n5(2)/(8)=(42)/(8)$

Subtract the baseball weight from the basketball weight to obtain the additional weight in the latter.

More weight=>

$(169)/(8)-(42)/(8)\n=(127)/(8)\n=15(7)/(8)$

Which point is on the graph of the equation y = 2x - 5?(3, -1)
(2, -5)
(4, 2)
(2, -1)

Answers

The x in this equation is the first number in the brackets, and the result of the equation is the second number in the brackets. So all that needs to be done is to substitute x for 3, 2 and 4 and see which one has the correct answer.
3 X 2 = 6. 6 - 5 = 1 (3, 1)
2 X 2 = 4. 4 - 5 = -1 (2, -1)
4 X 2 = 8. 8 - 5 = 3 (4, 3)

The only one of those coordinates that are the same as any of the given answers are (2, -1). Therefore, that is the answer.

You can draw a quadrilateral with no parallel lines and at least one right angle.TRUE OR FALSE

Answers

The answer is true. All you need is one 90 degree angle, two 50 degree angles, and one 170 degree angle. This creates a weird looking shape that is a quadrilateral with no parallel lines and at least one right angle.

Answer:

It is true

Step-by-step explanation:

Which of the following is NOT true? Question 19 options: (3x2y5)3=27x6y15 (1000x12y20z−3)0=1 52‾‾√3=523 42×43= 165

Answers

Answer:

Step-by-step explanation:

Lets try to simplify each to check which one is incorrect so it will be NOT true

first one is :

distribute the exponent so :

$(3x^2y^5)^3 =3^3x^(2*3)y^(5*3)$

$27x^6y^(15)$ CORRECT

Second one is :

$(1000x^(12)y^(20)z^(-30))^(0) =1$

CORRECT because anything raised to exponent 0 is 1 .

Last one is :

$4^2 *4^3 = 4^(2+3)\n=4^(6)\n=(4)^(2*3)\n=16^(3)$

so Last is INCORRECT

the absolute value is 7.

since it is absolute value you would simply make it a positive number. That works for any number. Just make it a positive. If it is already a positive keep it the same.
