One litre of milk is poured into a cylindrical container of radius 10 cm. Calculate the depth of the milk in cm)to 2 dp. ( take pi = 3.142)
Answer:
Depth=3.18cm
Step-by-step explanation:
V=πr2h
1LITRE=1000CM3
v=1000cm³
1000cm3=3.142×10²×Depth
Depth= 1000/3.142×100
Depth=3.18cm
81 divided by 7 plz just answer it
Answer:
11.57142857 (it doesn't go in evenly)
the result of 81 divided by 7 is 11 with a remainder of 4, which can be expressed as the mixed number 11 4/7 or the improper fraction 81/7.
When dividing 81 by 7, we can determine how many times 7 can be subtracted from 81 without going into negative values. By repeatedly subtracting 7 from 81, we find that 7 can be subtracted 11 times before reaching 4, which is less than 7. Therefore, the quotient is 11. However, there is a remainder of 4 left over.
So, the result of 81 divided by 7 is 11 with a remainder of 4, which can be expressed as the mixed number 11 4/7 or the improper fraction 81/7.

Olivia Earns $14 per hour at her job and receives a weekly bonus $100. Her total pay for the week of X hours is given by f(x)=100+14x. What is the reasonable domain and range?
Answer:
Step-by-step explanation:
Given the total pay for the week of X hours given by f(x)=100+14x, the domain of the function is the value of the input variable x for which the function exists. Since her to total week cannnot be negative, hence the value of x for which the function occurs is on all positive integers. This is represented according to the set notation;
Domain = [0, ∞)
The range of the function is the value of the output variable f(x) for all vaues of x for which the function occurs. Snce the minimum value of x is 0, the minimum value of the function will be at f(0);
f(0) = 100 + 14(0)
f(0) = 100 + 0
f(0) = 100
Hence the range of the function will be expressed as;
Range = [100, ∞)

Evaluate the expression |- 15| + | -7|
Answer:
Step-by-step explanation:
The lines in between the numbers are called absolute value bars. Whenever you see numbers that have absolute value bars, know that the numbers become positive.
Therefore,
|-15| = 15
|-7| = 7
Now we just add,
15+7=22
Final answer = 22
Jessica is saving money to buy a phone that costs $415. She already has $85 saved. She mows lawns to make extra money. She charges $15 per lawn that she mows. Let n be the number of lawns she needs to mow to have enough money saved to buy the phone. Which could be used to find how many lawns she needs to mow?
Answer:
22 lawns
Step-by-step explanation:
Phone= $415
Saved = $85
Money needed: $415 - $85 = $330
1 law mowed = $15
# of lawns needed to be mowed: $330 ÷ $15 = 22 lawns
Ans. = 22 lawns

please help...given that elm and oak street are parallel, find m
Answer:
102°
Step-by-step explanation:
(3x - 12)° + (2x + 2)° = 180°
5x - 10 = 180 ⇒ x = 38
m∠A = (3x - 12)°
m∠A = (3×38 - 12)° = 102°
Answer:
∠a = 3x -12 ( Being corresponding angle)
Now
(3x-12) + (2x + 2) = 180 ( Sum of straight angles)
5x - 10 = 180
5x = 190
x = 38
m∠a = 3x -12 = 3*38 -12 = 102

Jennifer bought some tulips, lilies, and roses to make bouquets. She bought the same number of tulips as lilies. She bought three more roses than tulips and lilies combined. She paid 18 cents for each tulip. The lilies were 27 cents per flower, and the roses cost 55 cents each. How many of each kind of flower did Jennifer buy if she paid $17.15 in all?
Answer:
z = 18.5
y = 15.5
x = 15.5
Step-by-step explanation:
Let
tulips = x
lilies = y
roses = z
x = y
z= x + 3 or y + 3
The equation is
0.18x + 0.27y + 0.55z = 17.15
Substitute x = y and z = y + 3 into the equation
0.18y + 0.27y + 0.55(y + 3) = 17.15
0.18y + 0.27y + 0.55y + 1.65 = 17.15
y = 17.15 - 1.65
= 15.5
x = y
x = 15.5
z = x + 3
= 15.5 + 3
= 18.5
Therefore,
z = 18.5
y = 15.5
x = 15.5

Find the missing factor A that makes the equality true
Answer: -4x^2
Step-by-step explanation:
Move point A to different locations to change the orientation of the parallel lines. (You'll notice that the tool keeps AB and CD parallel to each other) Be sure that points A and B do not cross EF. Do the relationships among the angles that you noted in questions 2 through 4 change if you modify the set of parallel lines this way? Explain.
Answer:
S.A for Edmentum and Plato
Like and Rate
No. For each set of parallel lines, pairs of alternate interior angles are congruent, pairs of alternate exterior angles are congruent, and pairs of same-side interior angles are supplementary. This is the same result as in questions 2 through 4.
No. For each set of parallel lines, pairs of alternate interior angles are congruent, pairs of alternate exterior angles are congruent, and pairs of same-side interior angles are supplementary. This is the same result as in questions 2 through 4.
How to explain the parallel linesIf we modify the set of parallel lines by moving point A to different locations while ensuring that points A and B do not cross line EF, the relationships among the angles will not change. The statements regarding pairs of alternate interior angles being congruent, pairs of alternate exterior angles being congruent, and pairs of same-side interior angles being supplementary will still hold true.
The reason for this is that the properties of alternate interior angles, alternate exterior angles, and same-side interior angles are dependent on the fact that lines AB and CD are parallel. As long as AB and CD remain parallel, regardless of the position of point A, these angle relationships will remain consistent.
