last night 80 people attended a lecture at the Smithfield Public Library 47th and 10 for men what ratio best represents the relationship between the number of men and the number of women

Answers

I encountered this question before. The correct phrasing of this question was:

Last night, 80 people attended a lecture at the Smithville Public Library. 47 of the attendees were men. What ratio BEST represents the relationship between the number of men and the number of women?

Given:
80 people
47 were men

80-47 = 33 number of women.

Number of men : 47
Number of women : 33

Ratio that best represents the relationship between the number of men and the number of women is 47 : 33.

A regulation basketball has a diameter of about 9 inches. What is the best approximation of the volume of the ball?3050 in3

84.8 in3

382 in3

215 in3

Answers

Answer:  The correct option is (C) 382 in³.

Step-by-step explanation:  Given that a regulation basketball has a diameter of about 9 inches.

We are to select the best approximation of the volume of the ball.

We know that basketball is of the shape of a SPHERE.

The VOLUME of a sphere with radius 'r' units is given by the formula:

V=(4)/(3)\pi r^3.

The diameter of the basketball is about 9 inches, so its approximate radius will be

r=(9)/(2)=4.5~\textup{inches}.

Therefore, the approximate volume of the basketball is

V\n\n\n=(4)/(3)\pi r^3\n\n\n=(4)/(3)* 3.14* (4.5)^3\n\n\n=(4*3.14* 91.125)/(3)\n\n\n=381.51~\textup{in}^3~\textup{[approx.]}\sim 382~\textup{in}^3.

Thus, the best approximation of the volume of the ball is 382 in³.

Thus, (C) is the correct option.

382 in3

Just look up volume of a sphere and a thing comes up all you have to put in is the radius (aka half of 9 which is 4.5) You're welcome.

7 × (–3) × (–2)2 = ?

A. 84
B. 48
C. –84
D. –48

Answers


7 × (-3) ×(-2)2 =

7 × -3 × -4 = (you have to eliminate all parenthesis in the equation.)

7 × -12 = -84

so your answer would be: C
7*-3=-21 and -2*2=-4 so -21*-4= 84
answer is 84

What is 99+1 x 4 worth 50 pts

Answers

Use PEMDAS to solve the problem.
PARENTHESIS
EXPONENTS
MULTIPLICATION
DIVISION
ADDITION
SUBTRACTION

In the problem 99 + 1 * 4, there is only multiplication and addition.
According to PEMDAS, multiplication comes before addition. So you do that first.
1 * 4 = 4
Now you add 4 and 99 to get your answer.
99 + 4 = 103
The answer is \boxed{ 103 }.

However, it looks like in your question the 99+1 is separated from the 4. If the question was originally (99 + 1) * 4 then we do the parenthesis first. 99 + 1 = 100. 100 * 4 = 400.

So depending on your question,
99+1*4=\boxed{103}
(99+1)*4=\boxed{400}
99+1 times 4
so pemdas
there are no parenthasees or exponents so we move to multiplication
1 times 4=4
99+4
addition
99+4=103
the answe ris 103
