Answer:
Carlos born in 1944
Julio born in 1945
Ricky born in 1946
Step-by-step explanation:
x = Carlos age
x+1 = Julio age
x+2 = Ricky age
x + x+1 + x+2 = 129
3x + 3 = 129
3x = 126
x = 42 (Carlos age)
x+1 = 43 (Julio age)
x+2 = 44 (Ricky age)
1990 - 42 = 1944 (year Carlos born)
1990 - 43 = 1945 (year Julio born)
1990 - 44 = 1946 (year Ricky born)
Can someone help me? I’ll reward 10 points + brainalist (I want an explanation and answer)
Answer:
B
Step-by-step explanation:
The area of a circle is
[tex]\pi {r}^{2} [/tex]
where r is the radius.
A radius is a line segment from the center of the circle to the circumference of a circle(any point that is on the arc).
It is given that x=1/3 so we use this equation.
Substitute 22/7 for pi
[tex] \frac{22}{7} ( \frac{1}{3} ) {}^{2} [/tex]
[tex] \frac{22}{7} \times \frac{1}{9} [/tex]
[tex] \frac{22}{63} [/tex]
Area is squared so we use in^2.
B is the answer

Hillary and her friends are trying to decide whether to go bowling or to a movie. Which method could they use to fairly decide which activity they
will do?
A.Flip a coin twice. If the coin lands on heads both times, they will go bowling. If it doesn't, they will go to a movie.
B.Flip a coin twice. If the coin lands on heads one time and tails one time, they will go bowling. If it doesn't, they will go to a
movie.
C.Flip a coin three times. If the coin lands on tails all three times, they will go to a movie. If it doesn't, they will go bowling.
D.Flip a coin three times. If the coin lands on heads twice and tails once, they will go to a movie. If it doesn't, they will go bowling.
Answer:
D.
Step-by-step explanation:
I would have to say D is the best answer since then it's truly based on luck and it's almost as if it's being flipped once
Hillary and her friends could flip a coin twice to fairly decide which activity they will do. If the coin lands on heads one time and tails one time, they will go bowling. If it doesn't, they will go to a movie.
What is probability?Probability is the ratio that shows the likelihood of an event occurring out of all the other possible events.
Hillary and her friends need to use a fair method to determine which activity to do. For this, the probability should be 1/2. We should observe the given options and find which is the fairer method.
In the case of option A, the probability of that event occurring is 1/4.In the case of option B, the probability of that event occurring is 1/2.In the case of option C, the probability of that event occurring is 1/8.In the case of option D, the probability of that event occurring is 3/8. We can see that Option B is the only event having a probability of 1/2.Therefore, Hillary and her friends could flip a coin twice to fairly decide which activity they will do. If the coin lands on heads one time and tails one time, they will go bowling. If it doesn't, they will go to a movie. The correct answer is Option B.

Answer:
Tropic Fresh Fruit Punch
Step-by-step explanation:
You have to find how many cups of concentrate both brands use per cup of water. To do that, you divide the cups of concentrate by the cups of water.
Tropic Fresh Fruit Punch - 22/10=2.2
Merry Berry Fruit Punch - 13/6=2.17 (rounded to the nearest hundredth)
Since 2.2 is bigger than 2.17, Tropic Fresh Fruit Punch has the more fruitier concentration of punch.

In circle O, central angle COD has a measure of 48. Find the measure of arc BC. In your final answer, include all your work
Answer:
Measure of arc BC = 132°
Step-by-step explanation:
Measure of the central angle COD = 48°
Therefore, measure of arc AB = 48°
Since, segment AC is a diameter and central angle for a diameter is 180°.
Measure of major arc ABC = 180°
measure of arc AB + measure of arc BC = 180°
48° + measure of arc BC = 180°
Measure of arc BC = 180° - 48°
= 132°

a student Miss 10 problems on an English test and received a grade of 44%. If all the problems were of equal value, how many problems were on the test
Answer:
Rounded to the nearest integer, the test had 18 problems in all.
Step-by-step explanation:
Given that a student missed 10 problems on an English test and received a grade of 44%, if all the problems were of equal value, to determine how many problems were on the test the following calculation must be performed:
100 - 44 = 56
56 = 10
100 = X
100 x 10/56 = X
1,000 / 56 = X
17.85 = X
Thus, rounded to the nearest integer, the test had 18 problems in all.

Solve for x. Round to the nearest tenth. 2.
39°
27
Answer:
33.3
Step-by-step explanation:
Reference angle = 39°
Opposite = 27
Adjacent = x
Apply TOA. Thus:
Tan 39 = Opp/Adj
Tan 39 = 27/x
x * Tan 39 = 27
x = 27/Tan 39
x = 33.3422232 ≈ 33.3 (nearest tenth)

50 POINTS! QUICKLY Are the pairs of variables x and y the solutions to the equation x^2–2y=7?
1. (5,8)
2. (-1,-3)
3. (-4,-11.5)
4. (1.2, -2.78)
These are all yes and no questions!
Hi there!
[tex]\large\boxed{(5,8) \text{ and } (1.2, -2.78)}}[/tex]
We are given the equation:
x² - 2y = 7
To verify if each ordered pair is apart of the function, we can plug in their respective x and y values:
1. (5)² - 2(8) = 7
25 - 16 = 9 ≠ 7. This is NOT correct.
2. (-1)² - 2(-3) = 7
1 + 6 = 7. This is correct.
3. (-4)² - 2(-11.5) = 7
16 + 23 = 39 ≠ 7. This is NOT correct.
4. (1.2)² - 2(-2.78) = 7
1.44 +5.56 = 7. This is correct.
Thus, only 1 and 4 are the correct answers.
No yes no yes
