Pretty, pretty, pretty please help!!!Which proportion models this problem?On a soccer team, 8 out of 19 players surveyed say they had two or more siblings. The league has 570 players. Which is the best prediction of the number of players in the league that have two or more siblings? A. x/8 = 19/570 B. x/570 = 19/8 C. x/570 = 8/19 D. x/19 = 8/570

Answers

8 of 19 players said that they had 2 or more siblings.

8 out of 19 is equal to what out of 570

8/19 = x/570

This proportion can be written in different ways.

8/19 = x/570 cross multiplies to 19*x = 8*570

The task is to find a proportion among the answer options that cross multiplies to the same equation.

Option C is x/570 = 8/19. That cross multiplies to 19*x = 8*570 and is the correct answer.

On a number line, will the square root of 20 be closer to 4.4 or 4.5

Answers

Answer:

4.5

Step-by-step explanation:

Nearest of square root of 20

$√(20)$

To choose closer from two numbers 4.4 or 4.5

First we find the square of both number.

Square of 4.4

$4.4^2 = 19.36$

Square of 4.5

$4.5^2=20.25$

Now compare the closer number from 20

Difference of, 20.25 - 20 = 0.25

Difference of, 20-19.36 = 0.64

As we know, 0.25<0.64

Hence, On number line square root closer to 4.5

Answer: 4.5 would be closer

Step-by-step explanation: 4.4x4.4 is 19.36 which is about 64 points away and 4.5x4.5 is 20.25 which is 25 points away

What is X Plus -8 equals 3x plus 6

Answers

x + -8 = 3x + 6
x - 8 = 3x + 6
(x - 8) + 8 = 3x + 6 + 8
x = 3x + 14
x - 3x = (3x + 14) - 3x
-2x = 14
2x = -14
x = -7

x=7 this is how you do it you just combine like terms but there isn't so you just add 8 to both sides so it would be x=3x+14 then you would subtract 3x to both side and it would be -2x=14 then divide by 2 not negative two and get x=7 because you can't have something equal negative x

What are 2 numbers that when multiplied together you get 360 and when added together you get -96

Answers

x + y = -96;
x * y = 360;

$t^(2) + 96t + 720 = 0$ ;
Δ = $96^(2) - 4 * 720 = 6336$ => sqrt(Δ) = 79.6;
=> x = ( - b + sqrt(Δ) ) / 2a => x = ( -96 + 79.6 ) / 2 ≈ - 8.2;
=> y = ( - b - sqrt(Δ) ) / 2a => x = ( -96 - 79.6 ) / 2 ≈ - 87.8;

Can anyone solve these problems

Answers

Answer:

Step-by-step explanation:

this is very easy.

add the wholes 4+1 then before you solve anything you can simplify. 2 goes into 2 once so now the problem looks like 1/1 x 1/3 the answer for the first one is 5 1/3

3. we are going to do the same thing add the wholes 2 and 1. and since we cant simplify any more you are just going to multiply across 1 times 1 and 2 time 5 the answer is 3 1/10

6. all you have to do for this one is add the wholes 8 1/3

7. add the wholes 2 and 9 is 11 then multiply across 3 times 1 and 5 times 2 write the problem out and it shall now look like this 11 3/10

2 is 6
3 is 3
6 is 16 and 2/3
7 is 24 and 7/10
