Answer:
323232÷121212
answer=2.66
Answer:
32 minutes
Step-by-step explanation:
Imagine that each person is assigned one wall, and all 8 people begin painting at the same time.
Since everyone will finish painting their assigned wall after 32 minutes, it takes one person 32 minutes to paint one wall.
If we have 12 people and 12 walls, we can again assign one wall to each person.
Everyone will take 32 minutes to paint their assigned wall.
In other words, it takes 32 minutes for 12 people to paint 12 walls.

Shen picks a rational number. What is true about the opposite of his number?
Answer:
It is the same distance from 0 as the original number
a rational number is any number that can be written as a fraction.
lets say she picked 1/4...the opposite would be -1/4...both are equidistant from 0.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Opposite: Shen's number changes sign, e. g., -2 to +2.
If you meant "reciprocal," then you must ensure that the denominator of the 'new' number is never zero. 3/5 => 5/3 is ok. But x/6 = 6/x is OK ONLY for x not equal to zero.

F and H are sets of real numbers defined as follows.
F={w | w>3}
H={w | w>6}
Write FUH and Fn H using interval notation.
If the set is empty, write Ø.
Answer:
[tex](a)F \cup H=(3, \infty)\\(b)F \cap H=(6, \infty)[/tex]
Step-by-step explanation:
Given the sets F and H of real numbers defined as given:
F={w | w>3}
H={w | w>6}
To write a set in interval notation, we use these brackets, ( ) for < or > while we use [ or ] for [tex]\leq $ or \geq[/tex].
Since our sets are defined by strict inequalities(< or >)
In interval notation
[tex]F=(3,\infty), H=(6,\infty)[/tex]
[tex](a) F \cup H =(3,\infty) \cup (6,\infty) \\\\F \cup H=(3, \infty)\\\\(b) F \cap H =(3,\infty) \cap (6,\infty) \\\\F \cap H=(6, \infty)[/tex]

Maria bought a bag of flour so that she can make muffins it has a mass of 2.26 kg Shanice 450 g of flour to make one batch of muffins how many kilograms of flour will remain after Maria make slime
Answer:
10 grams or 0.010kg
Step-by-step explanation:
The mass of the bag used to make flour is 2.26 kg = 2260 grams
Now, in order to find out how many badges she made, we would need to divide the weight of the bag by the amount needed to make a badge.
Therefore: [tex]\frac{2260}{450} = 5.02[/tex]
We know now that the bag will make 5 batches and will have some left over. In order to find how much we used, we can multiply 5 * 450 = 2250.
Therefore, in order to make 5 batches, Maria used exactly 2250 grams of flour which in result left us with 10 grams of the bag.
Note: 2260 -2250 = 10 grams.
Subtract, in order to find how many you have left.
Hope this helps.
After making one batch of muffins, Maria will have 1.8 kg of flour remain.
What is 1 kg when it is converted into grams?
1 kg will be 1000 grams when converted.
Given,
Maria bought 2.26 kg of flour = 2260 grams of flour.
To make 1 batch of muffins, Maria needs 450 grams of flour.
Therefore, the flour Maria has after making one batch of muffin = (2260 - 450) grams = 1810 grams.

Lee has a bag with 500 quarters. Some are the older eagle quarters, and others are the newer state quarters. She pulls out 10 quarters at random. Four are eagle quarters, and 6 are state quarters. Based on this sample, how many of the quarters in the full bag were likely to be eagle quarters? 400 200 100 300
Answer:
400
Step-by-step explanation:
The number of eagle quarters likely to be in the bag is 200.
Option B is the correct answer.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of quarters = 500
Out of the 10 quarters.
Eagle quarters = 4
This means,
Percentage of eagle quarters,
= 4/10 x 100
= 40%
Now,
40% of 500 quarters.
= 40/100 x 500
= 200
Thus,
The full bag is likely to have 200 eagle quarters.

Come up with your own system to measure angles. What would you call your unit of measure and how would it work. Describe your system and give some examples of typical angle measures like the corner of a room or a slice of pizza.
Answer:
You can try a picture memory method to help students
An example write down notes of what the triangle laws are for angles.
Then interpret them into your picture measurement theory.
Example could be the perpendicular measures of a right angle can be used
to find an area would be the M but as we are finding angles we could use the Big A instead of degrees sign.
We could provide pictures of cars to represent trigonometry
Where back wheels opposite angles and sides from slant are both the unit measure used in Side/sin( A) x sin (B) so this way you label the car wheel angle above of the square boot 'side on' and this angle is A
The B is the one above it linking the slant to find the other measure.
You are asked to design a theme around measuring angles so you need to look at other sin cos and tan calculus to design a picture that can create an image like i've given to find slant.
You need to one that finds angles.
However if you do find a car can help you can always call it square boot as in square root, considering 2/3 of sin cos and tan are square root measures.
Step-by-step explanation:
See the attached ideas and trigonometry
Picture memory Trigonometry
Picture 1. Sunrise Ah side looks for side measure.
The number above is the hypotenuse
A/H = cos ( ) x hyp =base A/H = cos ( ) x hyp = side
Picture 2.Sunrise Soh looks for side measure.
The number above it is the hypotenuse
O/H = sin ( ) =p (for product) take the p x hyp.
Picture 3 Sunrise Toast (Toa) looks for side measure = O/A
Tan ( lower angle ) x base = side
Picture 4 Side of car (Soh) with window as hypotenuse.
Two wheels are the 2 angles given and the back seat is perpendicular to both wheels =
so the triangle structure looks like this /00|7
so you type in 7/sin ( 1st wheel) x (2nd wheel) = hypotenuse.
Both angles given or worked out this is when this is used.
Picture 5 Electric mast looking for slope SIN =S/P = O/A
Angle at top
We have the side at 70 and looking for the slope
Sin( top angle) = p then side/p = hyp
Picture 6
Top angle and base given creates a T this means half both of them before dividing.
To find hypotenuse
Half = 1/2 base / sin (1/2) = hypotenuse
Picture 7
Top angle and base given creates a T this means half both of them before dividing.
To find height =
Half = 1/2 base /Tan 1/2) = Triangle height.
Key checker after pictures are drawn is;
sunrise = low angle x side or low angle x base = hypotenuse.
car = backseat x wheels = hypotenuse always remember when car on side the first
wheel first, second wheel 2nd first in the calculator. The wheels are the 2 angles that
make the car when flipped.
Half = 1/2 base / sin (1/2) = hypotenuse
Half = 1/2 base / tan (1/2) = height
Just take care with top angle and lower angle key words in the drawing descriptions and then the pictures will help.
The following function is continuous at all points in the domain of real numbers. What is the value of n?

4x, if x [tex]\leq[/tex] n
A. -1
B. 0
C. 1/2
D.1
Answer:
D. 1Step-by-step explanation:
To solve this problem, we just need to find the common point of these linear function, beacuse they form a piecewise function which is continuous according to the problem, that means they are related by one common point.
Let's solve the following expression [tex]f(x)=g(x)[/tex], where [tex]f(x) =2x+2[/tex] and [tex]g(x)=4x[/tex]. So,
[tex]2x+2=4x\\2=4x-2x\\2x=2\\x=1[/tex]
Which means [tex]n=1[/tex], that is, if the n is greater than 1, then the function is defined by [tex]f(x)[/tex], if the n is least or equal than 1, then the functioni is defined by [tex]g(x)[/tex]
Therefore, the right answer is D.
Answer:
1. A, -1
2. D, 1
3. B, It is discontinuous because there is a value a for which f(a) is not defined 4. D, It is discontinuous because there is a value a such that lim f(x) does not exist

What is the volume of a hemisphere with a radius of 9.2 cm, rounded to the nearest tenth of a cubic centimeter?
Answer:
volume of the hemisphere ≈1577.5 cm³
Step-by-step explanation:
To find the formula for calculating the volume of a hemisphere, we will follow the steps below:
write the formula for calculating the volume of a hemisphere.
volume of a hemisphere = volume of a sphere ÷2
= [tex]\frac{4}{3}[/tex]πr³ ÷ 2
=[tex]\frac{2}{3}[/tex] πr³
WHERE r is the radius
from the question given, radius= 9.2 cm
π is a constant and is ≈ 3.14
we can now proceed to insert the values into the equation
volume of a hemisphere = [tex]\frac{2}{3}[/tex] πr³
= [tex]\frac{2}{3}[/tex] × 3.14 ×9.2³
= [tex]\frac{2}{3}[/tex] × 3.14 ×753.571
≈1577.5 cm³ to the nearest tenth of cubic centimeter
volume of the hemisphere ≈1577.5 cm³
