Answer:
9/24 or 3/8
Step-by-step explanation:
Spinner gives a 4.
Suppose the 4 shows up on the spinner.
There is a 1/4 chance of that happening.
Suppose the cube does not have a 4 on the top face. There is a 5/6 chance of that happening
Together the probability is 1/4 * 5/6 = 5/24
The cube gives a 4
The cube gives a four 1/6 of the time.
The spinner cannot give a 4, which happens 3/4 of the time.
Together the probability is 1/6 * 3/4 = 3/24
Both Cube and Spinner give a 4
The cube will give a four 1/6 of the time
The spinner gives a four 1/4 of the time.
1/6*1/4 = 1/24
Total
1/24 + 3/24 + 5/24 = 9/24 = 3/8
What happens to the rest?
The answer is neither gives a four.
Spinner 3/4
Die: 5/6
Combined amount = 3/4 * 5/6 = 15/24
There is a quick way to do this.
1 - no fours =
1 - 15/24 = 9/24
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.
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

Use the grouping method to factor the polynormial below completely. 10x^3 - 35x^2 + 6x - 21
The polynomial 10x^3 - 35x^2 + 6x - 21 is factored using the grouping method to obtain (2x - 7)(5x^2 + 3).
To factor the polynomial 10x^3 - 35x^2 + 6x - 21 using the grouping method, we first look for a common factor in each group separately and then factor out the common binomial factor.
Split the polynomial into two groups: (10x^3 - 35x^2) and (6x - 21).
Factor out the greatest common factor from each group: 5x^2(2x - 7) and 3(2x - 7).
Now we have 5x^2(2x - 7) + 3(2x - 7). Since both terms have a common binomial factor of (2x - 7), we can factor this out: (2x - 7)(5x^2 + 3).
So, the factored form of the polynomial 10x^3 - 35x^2 + 6x - 21 using the grouping method is (2x - 7)(5x^2 + 3).

Jorge has $138.22 in his savings account. He deposits $10.75 every week and withdraws $31.68 every four weeks. What will his balance be in 8 weeks?
Answer:
Pretty sure the answer is $160.86
Step-by-step explanation:
you start off by multiplying 10.75 x 8 because that's how much he'll deposit at the end of an 8 week spand.
adding 86+138.22= 224.22
then you subtract 31.68 two times from that as he withdraws 2 times in the 8 weeks, giving you the answer of 160.86.

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.

D) a reflection, then a translation.
Answer:
B) a rotation, then a reflection
Step-by-step explanation:
you will make a rotatio of 90° about clockwise and reflection about Y- axix
Answer:
B) a rotation, then a reflection.
Step-by-step explanation:
From the given graph, the white shape transformed into blue shape.
If you look at the white shape and the blue shape.
The white shape rotated 45° counter clock wise and reflected over the origin x = y to get the blue figure.
For example, let's take a vertex (2, -1) in the white figure. The corresponding in the blue shape is (-2, 1) which is reflection about the origin.
Therefore the answer is B) a rotation, then a reflection.

Point P (-1, 2) is the center of a circle. The radius of the circle is 3 units. Which point lies on the circle? PLEASE HELP!
Answer:
(2,2), (-1,5), (-3,2), (-1,-1)
Step-by-step explanation:
The radius is the distance from the center of the circle to the outside. So, adding or subtracting 3 from the x-value of the center point will give you a point that lies on the circle. Doing the same to a y-value will as well. However, never add or subtract from both.

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

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

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
