Which is the best estimate for 19% of 205?
• A. 40
• B. 50
• C. 100
• D. 400
Answer:
A
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
100 would be half way or 50% of 205
And, 50 would be around 25 to 30%
So, logically A would be your answer.

Can anyone please help me with this? You need to find the equation to solve for x, the value of x, and the value of each angle measure for all 5 questions. I will give brainliest
Answer:
[tex]1. 3x+21 = 6x-60\\or, 6x-3x = 21+60 [Being~corresponding~angles]\\or, 3x = 81\\or, x = 27.\\Equations: 3x+21=6x-60\\Value ~of ~x = 27\\Angle ~measure = (3x+21), (6x-60) = 3(27)+21,6(27)-60 = 102,102\\[/tex]
[tex]2. 12x - 18 = 8x+10 [Being~vertically~opposite~angles]\\or, 12x - 8x = 18+10\\or, 4x = 28\\or, x = 7\\Equations: 12x-18 = 8x+10\\Value~ of~ x: 7\\Angle ~measure: (12x-18),(8x+10) = 66,66\\[/tex]
[tex]3. Have~a~look~at~the~figure.\\Here, y = 3x+9 [Being~ vertically ~opposite ~angles]\\Also, y+5x+3 = 180^{o} [ Being~cointerior~angles]\\or, 3x^{o}+9^{o}+5x^{o}+3^{o}=180^{o}\\or, 8x^{o}+12^{o}=180^{0}\\or, 8x^{o} = 168^{o}\\or, x = 21^{o}\\So, 3x+9 = 3(21)+0 = 72^{o} ~and ~5x+3 = 5(21)+3 = 108^{o}\\Equations: y = 3x +9, y+5x+3=180^{o}\\Value ~of~ x: 21^{o}\\Angle ~measure: 72^{o},108^{o}[/tex]
[tex]4.~~~~ (3x+10)^{o}+(3x-28)^{o} = 180^{o} [Being~cointerior~angles]\\or, ~~~6x -18^{o} = 180^{o}\\or, 6x=198^{o}\\or, x = 33^{o}\\So, 3x+10 = 3(33)+10 = 109^{o}~and~3x-28 = 3(33)-28 = 71^{o}\\Equations: 3x+10+3x-28 = 180^o\\Value~ of~ x: 33^o\\Angle~measure: 109^o,71^o\\[/tex]
[tex]5. Solution,\\12x+15 = 15x [Being ~alternate~angles]\\or, 15x-12x = 15\\or, 3x=15\\or, x = 5^{o}\\So, 12x+15 = 12(5)+15 = 75^o = 15x\\Equations: 12x+15=15x\\Value~of~x: 5^o\\Angle ~measure: 75^o,75^o[/tex]

A baseball team wins 70% of its games.
Assuming this trend continues, which simulation can you use to model the team's wins over the next three games?
A. Place 3 green and 3 red marbles in a bag. Let the green marbles represent a win and the red marbles represent a loss. Randomly pick one marble to simulate the first game. Replace the marble and repeat two more times. This is one trial. Run 30 trials.
B. Place 3 green and 3 red marbles in a bag. Let the green marbles represent a win and the red marbles represent a loss. Randomly pick one marble to simulate the first game. Without replacing the marble, pick a second time and then a third time. This is one trial. Run 30 trials.
C. 7 green and 3 red marbles in a bag. Let the green marbles represent a win and the red marbles represent a loss. Randomly pick one marble to simulate the first game. Replace the marble and repeat two more times. This is one trial. Run 30 trials.
D. Place 7 green and 3 red marbles in a bag. Let the green marbles represent a win and the red marbles represent a loss. Randomly pick one marble to simulate the first game. Without replacing the marble, pick a second time and then a third time. This is one trial. Run 30 trials.
Use the simulation results to find the experimental probability that the team wins the next three games. Round your answer to the nearest percent.

Justify each step used to simplify the expression. 1. 3x+ 2y− 2x+ 2 = 3x− 2x+ 2y+ 2
Answer:
.
Step-by-step explanation:
well let’s think about it this way. we can take the like numbers and add or subtract them right? so let’s think of all the like numbers.
3x, -2x, and 2x are like numbers
2y, and 2y are like numbers
2 and 2 are like numbers.
now that we have all of the like numbers down, lets start with the first set of numbers before the = sign.
3x+ 2y- 2x+ 2
well since we have 2 like numbers in there, let’s add those, so we have 3x + 2x, which that would give us 5x. since we have nothing else in that, out expression for that one would be 5x + 2y + 2. next one we have:
3x - 2x+ 2y+ 2
we have like factors in this one too. since we have a subtraction sign in between them, we have to take 3x - 2x which gives us 1x or x. which that expression would be (x + 2y + 2). if you have to add the expressions together the whole thing would be (6x + 4y + 4).
if the (-) is supposed to be a negative, then the problems would be, x + 2y+ 2; x + 2y + 2. which the ending would be 2x + 4y + 4. hope this helps. if i’m wrong someon correct me.

What is the volume of this sphere?
Answer:
113
Step-by-step explanation:
if you can't do all of them it's ok but if you do some put which number it is. also write it like 11). x = 7 (not real answer).
Answer:1. x=11
Step-by-step explanation:
For the rest of the questions to do inverse operation! it says x+7=18.... ask yourself 7 plus what give me 18 use a calculator or paper subtract 18 from 7 and it gives you your answer which is 11.
For the ones like number 4. You do the same thing but instead of subtracting you add 6+3 it will give you 9 and to make sure sure add the numbers together. what ever number you get you plug the number into your equation and the statement should be true.

The Vindale Times had 9,930 subscribers last year. This year, after the paper was bought out, it had 50% more. How many subscribers were there this year?
Answer:
there are 14,895 subscribers this year
Step-by-step explanation:
50% of 9930 is 4965, and just add 9930 to that
Answer:
14,895 I think
Step-by-step explanation:
Well 9,930 is a whole so it equals 100 percent. If we add another 100 percent you get 19,860 ( 9,930 plus 9,930) and since it is only 50 percent we add half of 100 percent which would be 4965 (9,930 divided by 2) and add it to the 100 percent because it was an increase by 50 percent. If you have any more questions I would be glad to help! Mark brainliest plz

Sabric and Jessica disagree over an inequality statement. Sabric claims that -3.613 > -3.63. Jessica claims that -3.613 < -3.63. Which statement about each student's claim is true?
Answer:
Sabric's claims is correct because when you have a negative number the lower number, in this case -3.613 is greater than -3.630/
This question is based on the concept of inequality. Sabric claims is -3.613 > -3.63. It is true that -3.613 is more than -3.63.
Therefore, Sabric claim is true.
Given that :
Sabric claims that -3.613 > -3.63.
Jessica claims that -3.613 < -3.63.
We have to prove that which statement about each student's claim is true.
According to the question,
As we know that,
Negative sign with higher value is smaller than negative sign with lesser value.
For example: -2 is less than -1.
In given question, it is observe that,
Sabric claims is -3.613 > -3.63. It is true that -3.613 is more than -3.63.
Therefore, Sabric claim is true.
Jessica claims that -3.613 < -3.63. Therefore, Jessica claims is not true because it is observe that, -3.613 is more than that of -3.63.
Therefore, Sabric claims is true.
