Answer:
hope it helps you
Step-by-step explanation:
Let
A be the set of students in art class
B be the set of students in dance class
n(A) = 35
n(B) = 57
a) When 2 classes meet at different hours and n(A ∩ B) = 12 we have:
n(A ∪ B) = n(A) + n(B) - n(A ∩ B) = 35 + 57 - 12 = 80
b) When two classes meet at the same hour we have A∩B = ∅ that is n(A ∩ B) = 0 and
n(A ∪ B) = n(A) + n(B) - n(A ∩ B) = n(A) + n(B) = 35 + 57 = 92
Need help with number 13
Answer:
x = 19
Step-by-step explanation:
the question tells you that the angle CBD is 90°.
so, that means that angle DBE and angle CBE add up to 90.
using this, you can make the following equation:
2x - 1 + 5x - 42 = 90
2x + 5x + -43 = 90
7x - 43 = 90
add 43 to both sides
7x = 90 + 43
7x = 133
x = 133/7
x = 19

6{[(600x10²)]} - [(3x5)x2]+5-10+2=
Answer:
359967
Step-by-step explanation:
6{[(600 x 10²)]} - [(3 x 5) x 2] + 5 - 10 + 2 =
= 6(600 x 100) - [15 x 2] - 5 + 2
= 6(60000) - 30 - 5 + 2
= 360000 - 35 + 2
= 359965 + 2
= 359967

What plus 32 equals 98
Answer:
66
Step-by-step explanation:
Answer:
Lets numeralise the question,
According to question 32+ ? = 98
So if we take the unknown value as x then we will get,
32+x=98
So by transposing we get,
x=98-32
= 66
So 66 should be added to 32 to get 98

Sohie’s mom cans jelly. She fills each jar with 1/2 a pint of jelly. If she made 1 7/10 pints of jelly, which expression can be used to find how many jars Sophie’s mom can fill?
Answer:
Number of jar Sohie's mom can make can be found out by dividing the total amount by the amount in one jar, so we can frame a equation like this,
Let the number of total jar be x,
x = (1 7/10) / 1/2
That is the answer, let us solve this equation,
x = 1 7/10 / 1/2
=> x = 17/10 * 2/1
=> x = 17/5 * 1/1
=> x = 17/5
17/5 = 3.40
Therefore, she can pack 3.4 jars of jelly.
If my answer helped, please mark me as the brainliest!!

Prove: a^2+b^2/2 ≥ab
We know that the square of any number is greater than or equal to zero ;
So if have a number like x :
[tex]( {x})^{2} \geqslant 0[/tex]
_________________________________
Now we have a number which is
( a - b ) ;
So we have :
[tex]( {a - b})^{2} \geqslant 0 [/tex]
##############################
Reminder :
[tex]( {a - b})^{2} = {a}^{2} - 2ab + {b}^{2} [/tex]
##############################
So we have :
[tex] {a}^{2} - 2ab + {b}^{2} \geqslant 0 [/tex]
Both sides plus 2ab :
[tex] {a}^{2} + {b}^{2} \geqslant 2ab [/tex]
Divided both sides by 2 :
[tex] \frac{ {a}^{2} + {b}^{2} }{2} \geqslant ab \\ [/tex]

Suppose there is a 3.1 temperature drop for every thousand feet that an airplane climbs
into the sky. If the temperature on the ground is 60.1, what will the temperature be
when the plane reaches an altitude of 11,000 feet?
Answer:
34.1 degrees
Step-by-step explanation:
given that the temperature drops 3.1 degrees for every thousand feet of elevation.
for an altitude of 11,000 feet (i.e 11 x 1000 feet), the temperature (compared to ground level) would drop,
= 3.1 deg / 1000-foot x 11,000 feet
= 34.1 degrees

12.) Given the following information, determine which lines, if any, are parallel. State the converse that justifies your answer. Pleaseee helppp
Answer:
Step-by-step explanation:
Given Parallel lines Converse
a. ∠13 ≅ ∠17 a║c Corresponding angles
b. ∠4 ≅ ∠9 d║e Exterior alternate angles
c. m∠20 + m∠21 = 180° a║b Consecutive interior angles
d. ∠8 ≅ ∠19 Vertical angles
e. ∠10 ≅ ∠23 b║c Interior alternate angles
f. m∠14 + m∠17 = 180° a║c Consecutive interior angles
From the given diagram and information, it can be concluded that lines a, b, and c are parallel, and lines d and e are parallel.
The given lines in the diagram are a, b, c, d, and e.
a. It is given that the measure of angle 13 is equal to that of angle 17.
Now, these two angles are made by lines a, c, and d. Now, the angles are corresponding and equal, and hence, lines a and c will be parallel.
b. It is given that the measure of angle 4 is equal to that of angle 9.
These two angles are made by lines d, e, and b. Now, the angles are alternate exterior and equal, and hence, lines d and e will be parallel.
c. It is given that the sum of the measure of angles 20 and 21 is equal to 180 degrees.
These two angles are made by lines a, b, and e. Now, the angles are supplementary and their sum is 180 degrees, and hence, lines a and b will be parallel.
d. It is given that the measure of angle 8 is equal to that of angle 19.
These two angles are vertically opposite angles between lines a and e.
e. It is given that the measure of angle 10 is equal to that of angle 23.
These two angles are made by lines b, c, and e. Now, the angles are alternate interior and equal, and hence, lines b and c will be parallel.
f. It is given that the sum of the measure of angles 14 and 17 is equal to 180 degrees.
These two angles are made by lines a, c, and d. Now, the angles are supplementary and their sum is 180 degrees, and hence, lines a and c will be parallel.
Therefore, it can be concluded that lines a, b, and c are parallel, and the lines d and e are parallel.

A teacher can spend as much as

$5.50 per ticket.
Which of the following inequalities represents the problem and could be solved to find the maximum number of students,
x, who could attend the movie?
The maximum number of students, x, who could attend the movie are,
⇒ x ≈ 21
What is Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
A teacher can spend as much as $125.00 to take students to a movie.
And, A movie theater charges a $10.00 group fee and $5.50 per ticket.
Let maximum number of students, x, who could attend the movie = x
Hence, We can formulate;
5.50x + 10 ≤ 125
Solve for x;
5.50x ≤ 125 - 10
5.50x ≤ 115
x ≤ 115 / 5.50
x ≤ 20.90
x ≈ 21
Thus, The maximum number of students, x, who could attend the movie are,
⇒ x ≈ 21
