= 6.28 units
A shelf is built on a wall, as shown below. What is the value of x?
Answer:
Step-by-step explanation:
Given:
A shelf is built on a wall. The angles of the triangle are given as (x + 3)°, (2x - 18)° and 90°
We need to determine the value of x.
Value of x:
By triangle sum property, the angles in a triangle always add up to 180°
Thus, we have;
Simplifying, we get;
Subtracting both sides by 75, we get;
Dividing both sides of the equation by 3, we get;
Thus, the value of x is 35.

A factory has a container filled with 35,874 litres of cold drink. In how many bottles of 21 L capacity each can it be filled ? How much drink will be left behind?
Answer:
Number of bottles= 1,708
Step-by-step explanation:
Giving the following information:
Total liters= 35,874 litres
Bottle capacity= 21 liters
To calculate the number of bottles that can be filled given the actual capacity, we need to use the following formula:
Number of bottles= total liters / cottle capacity
Number of bottles= 35,874 / 21
Number of bottles= 1,708

Explanation:
Angles 1 and 3 are vertical angles. Note how line t and line r intersect to form an X shape. Angle 1 and angle 3 are opposite angles in this X configuration, which is what makes them vertical angles. Vertical angles are always congruent.
Angle 1 is congruent to angle 2 if and only if both angles were 90 degrees (note the angles are supplementary). Otherwise, they aren't congruent. That allows us to rule out choice A. Choice C is ruled out for the exact same reason.
Of the 10 kids in a chess club, 5 are left-handed and 5 are right-handed. The club holds a round-robin tournament in which every player plays against every other player exactly once. Of all the matches, how many of them have a left-handed player competing against a right-handed player?
The total number of games a girl play against a boy is 25, the number of games a girl plays against a boy is 10, the fraction of the games are boy-versus-boy is 2/9, and 1/5 fraction of all games at the tournament Anita plays the game.
We have given that,
Of the 10 kids in a chess club, 5 are left-handed and 5 are right-handed.
What are permutation and combination?A permutation can be defined as the number of ways a set can be arranged, order matters but in combination, the order does not matter.
We have 5 girls and 5 boys in a chess club:
There are a total of 5×5 games girls play against a boy.
= 5×5
= 25
The number of games a girl play against another.
It is a combination problem so the total number of games:
= 10
A fraction of the games are boy-versus-boy:
The number games boy-versus-boy = 10
The number games Boy vs Boy & Girl vs Girl & Boy vs Girl
= 10+10+25
= 45
So the fraction = 10/45 ⇒ 2/9
If Anita is one of the club members then Anita will have to play against 9 people at the tournament.
Total number of games = 45
Then the fraction = 9/45 ⇒ 1/5
Thus, the total number of games a girl play against a boy is 25, the number of games a girl plays against a boy is 10, the fraction of the games are boy-versus-boy is 2/9, and 1/5 fraction of all games at the tournament Anita play the game.

The student council at Jefferson High School
sold a total of 220 brownies and cookies during
its fund-raiser. Each brownie sold for $0.75,
and each cookie sold for $0.50. The student
council made $136.50 from the sales of
brownies and cookies. Which system of linear
equations can be used to find b, the number
of brownies sold, and c, the number of cookies
sold?
A. b + c = 220
0.506 + 0.75c = 136.50
B. b + c = 136.50
0.75b + 0.50c = 220
C. b + c = 136.50
0.50b + 0.75c = 220
D. b + c = 220
0.75b + 0.50c = 136.50

True or false help me
Answer:
A. 4/12, C. 1/3
Step-by-step explanation:
2/6 can be divided by 3. Therefore, the fraction is 1/3.
A. 4/12 can be divided by 4. This means the fraction will be 1/3. Because 1/3 is equal to 1/3, this option is correct.
B. 1/2 cannot be simplified. Because 1/3 is not equal to 1/2, this option is not correct.
C. 1/3 cannot be simplified. Because 1/3 is equal to 1/3, this option is correct.
D. 3/8 cannot be simplified. Because 3/8 is not equal to 1/3, this option is not correct.

(order them in numerical value, least to greatest)
take off one number from each side until you have one number left
Answer: 78
Step-by-step explanation: The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average. Write all of the numbers and cross out a even amount of numbers on both sides. Image 1 shows your problem. If your problem had another number, you solve it differently. Check image 2.
1/3 x 1/4 = ?????????
Answer:
1/12
Step-by-step explanation:
1/4 X 1/3 = 1/12
Answer:
1/12
Step-by-step explanation:
When multiplying fractions, you multiply it like normal numbers, so 1 is multiplied by 1, and 3 is multiplied by 4.
For example:
3/4 x 9/10 would be equal to 27/40 because the 3 is multiplied by 9 and 4 is multiplied by 10.
3 x 9 = 27
4 x 10 40
27/40
Therefore on your question it would be 1/12.
A recipe calls for 2 cups of flour to make a cake that feeds 8 people. You are having a party for 60 people and therefore need more flour. You go to the store and find that they only have one kind of flour which is sold in bags of 32 ounces. So how many bags of flour do you need to buy? (note that 1 cup is 8 ounces)
Answer: 4 bags
Step-by-step explanation:
2 cups = 16 ounces
So using a proportion
16 / 8 = x / 60 where x is the number of ounces we need to buy
cross-multiply
16 * 60 = 8 * x
960 = 8 x
960 / 8 = x = 120 ounces
The number of bags we need = ceiling [ 120/32 ] = 4 bags
