what is the best desert in a math teachers cafe law of sines riddle
is a good desert. people love cake
Final answer:
The question regarding the "best desert in a math teacher's cafe" related to the Law of Sines is likely a pun involving math terms, with "pi" being the intended humorous answer due to its dual significance as a mathematical constant and a type of dessert.
Explanation:
The "best desert in a math teacher's cafe" when mentioned alongside the Law of Sines is likely a playful riddle rather than a straightforward question. The Law of Sines is a mathematical formula used in trigonometry to find missing angles or sides of a triangle, given enough information. It states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is constant for all three sides and angles in the triangle. Therefore, this riddle might be a pun or a play on words related to mathematics or trigonometry terms rather than an actual desert item.
In essence, to solve such riddles, one needs to think creatively, connecting the concept of desert with mathematical terms or principles. A common pun could be "pi," as it sounds like "pie," a type of dessert, and is also an essential constant in mathematics used to calculate the circumference and area of a circle. In the context of a math-themed cafe, "pi" could very well be considered the "best dessert," cleverly linking the world of mathematics with culinary delights in a humorous way.

Ky wants to buy three shirts, which were originally priced 49.96 each. The store will discount the price of the third shirt by 50% and then apply a 7.1% tax to the total cost of all three shirts. Including the tax, what will be the mean cost of each shirt?
49.96 + 49.96 + (49.96x.5)
99.92+24.94=124.86 divide 7.1 and 124.86 which gives you 17.58591549295775 but I’m guessing u round so 17.59 and add that to 124.86which equals 142.45. The total cost is 142.45. But each shirt is 49.96 and the third is 24.94. Don’t forget the dollar sign and have a good day! :)

How do you solve 16 = 17 - t
So I looked it up on another math helper app called ( Socratic )and this is what popped up on my screen Simplifying
16 = 17 + -1t
Solving
16 = 17 + -1t
Solving for variable 't'.
Move all terms containing t to the left, all other terms to the right.
Add 't' to each side of the equation.
16 + t = 17 + -1t + t
Combine like terms: -1t + t = 0
16 + t = 17 + 0
16 + t = 17
Add '-16' to each side of the equation.
16 + -16 + t = 17 + -16
Combine like terms: 16 + -16 = 0
0 + t = 17 + -16
t = 17 + -16
Combine like terms: 17 + -16 = 1
t = 1
Simplifying
t = 1

Step-by-step explanation:
Michael is organizing 5,272 blocks into bins at the toy store. He needs to put the same number of blocks in each bin without any leftover blocks. How many bins could Michael use for the blocks? A) 3. B) 4. C) 5. D) 9.
B. plz mark brainly
Answer: B) 4 bins
Step-by-step explanation:
The criteria of divisibility are rules that serve to know if a number is divisible by another without having to perform the division.
Divisibility by 3 (or 9)A number is divisible by 3 (or 9) if and only if the sum of its digits is divisible by 3 (or 9).
5,272
5 + 2 + 7 + 2 = 16
1 + 6 = 7 →This number isn't divisible by 3, therefore 5,272 isn't divisible by 3
Divisibility by 5Divisibility by 5 is easily determined by checking the last digit in the number , and seeing if it is either 0 or 5. If the last number is either 0 or 5, the entire number is divisible by 5.
5,272 → the last digit is 2; isn't 0 or 5, therefore 5,272 isn't divisible by 5.
Divisibility by 4The basic rule for divisibility by 4 is that if the number formed by the last two digits in a number is divisible by 4, the original number is divisible by 4
5,272
the last two digits are 72, and 72/4 = 18
72 is divisible by 4, therefore 5,272 is divisible by 4
Since 5,272 is divisible by 4, Michael can use 4 bins to organize the blocks, and he needs to put 5,272/4 = 1,318 blocks in each bin.
Answer: B) 4 bins

An office manager reported that he spent $350 on gifts for employees. He said that $240 was spent on clothing with each man receiving a $20 T-shirt and each woman receiving a $40 sweatshirt. He said that $110 was spent on desk accessories with each man receiving a $5 calendar and each woman receiving a $15 stapler. If m equals the number of men and wequals the number of women, the system of equations that represents the expenses is as follows:
m+2w=12
m+3w=22
Answer:
So I assume we are figuring out the number of men and women here, so:
m + 2w = 12
m = 12 - 2w
12 - 2w + 3w = 22
w = 10
m + 2w = 12
m + 2(10) = 12
m + 20 = 12
m = -8

Step-by-step explanation:
Circular flower bed is 17 m in diameter and has a circular 2 around it is that to meters wide find the area of the sidewalk in square meters use 3.14 for pi
The area of the sidewalk surrounding a circular flower bed with a diameter of 17 meters and a 2-meter wide sidewalk is 119.32 square meters.
The question involves finding the area of a sidewalk that surrounds a circular flower bed. The flower bed has a diameter of 17 meters, and the sidewalk is 2 meters wide. This is a geometry problem that requires us to calculate the area of two circles and then find the difference between them.
Calculate the radius of the inner circle (flower bed): radius = diameter / 2 = 17 m / 2 = 8.5 m.
Calculate the area of the inner circle using the formula A = 3.14 * 8.5 m * 8.5 m = 226.865 m
Calculate the radius of the outer circle (flower bed + sidewalk): radius_outer = radius_inner + width of the sidewalk = 8.5 m + 2 m = 10.5 m.
Calculate the area of the outer circle: A_outer = 3.14 * 10.5 m * 10.5 m = 346.185 m.
Calculate the area of the sidewalk by subtracting the area of the inner circle from the area of the outer circle: Area_sidewalk = A_outer - A_inner
= 346.185 m - 226.865 m
= 119.32 m.
The area of the sidewalk is 119.32 square meters.
For the right triangle shown, what is the tangent of angle A?
A) 2/3
B) 3/2
C) 3/4
D) 4/3
Answer:
The correct answer is option C 3/4
Step-by-step explanation:
It is given a right angled triangle ABC
To find the value of x
Hypotenuse² = Base² + height²
(x + 2)² = x² + (x + 1)²
x² + 4x + 4 = x² + x² + 2x + 1
x² -2x -3 = 0
We get x = 3 and x = -1
We take positive value x = 3
To find Tan A
Tan A = Opposite side/Adjacent side
= BC/AB = x/(x + 1) = 3/4
Therefore the correct answer is option C. 3/4
