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
what is X for this 4x/3-3x+1=10

First:
1. Find out the price of one can
A: $2.50 is per can
B: $1.92 is per can
C: $2.22 is per can
D: $1.54 is per can
The second step is:
Eliminate the most expensive
So, what we have left is

A 2 1/2 pound bag of grass seed covers 1/8 of an acre.How much grass seed is needed for 1 acre
Answer: 8 times more 8*2 1/2 = 20 pounds.
Step-by-step explanation: If 2.5 pounds cover 1/8 then simply multiply the 2.5 by 8, since you'll need 8/8. 8/8=1.
I hope this helps :)
There were 124 people at a concert. Admission was $5 each for adults and $3 each for children. A total of $444 was collected from admissions. How many adults and how many children attended?
Answer:
The answer is 36 adults and 88 children.
Step-by-step explanation:
The two equations are:
x+y=124 and 5x+3y=444
Using substitution method:
5x+3(124+x)=444
5x+372-3x=444
2x=72
x=36
5(36)+3y=444
180+3y=444
3y=264
y=88
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
hope this helps
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
a pump fills a pool at a constant rate at the end of 9 minutes it has filled 1 gallon of water which table represents the relationship between the number of minutes and the number of gallons of water in the pool
Answer:
D
Step-by-step explanation:
The rate at which the pool is filled is 1 gallon per 9 minutes. If you divide all the numbers of minutes in the left side of the table with the number of gallons on the right you get 9 minutes per gallon for each of them so they follow the rate.

There is a line that includes the point (1, 7)and has a slope of 7. What is its equation in slope-intercept form?
Answer:
y=7x
Step-by-step explanation:
When finding the slope intercept form using 2 points, we do the following.
y=mx+b (Slope intercept from)
y=7x+b (7 is slope)
Substitute the point
7=7(1)+b
7=7+b
b=0
y=7x
The slope intercept equation is y = 7x
-2(b-5)=16 x when b is 3 is
Answer:
When B is 3, it is not answerable. The sides are not equal, if it were -3 the answer would be 16.

state the multiplicity for each root
[tex]3(x^{2} + 5)^ {2} ( {x}^{2} - 25)^{3} (x - 8)^{4} = 0[/tex]
state the multiplicity for each root
Answers:
The two complex or imaginary roots [tex]x = i\sqrt{5}[/tex] and [tex]x = -i\sqrt{5}[/tex] have multiplicity 2.The two real roots x = 5 and x = -5 have multiplicity 3The root x = 8 has multiplicity 4======================================================
Explanation:
We'll use the zero product property to solve.
[tex]3(x^2+5)^2(x^2-25)^3(x-8)^4 = 0\\\\(x^2+5)^2=0 \text{ or } (x^2-25)^3=0 \text{ or } (x-8)^4 = 0\\\\x^2+5=0 \text{ or } x^2-25=0 \text{ or } x-8 = 0\\\\x^2=-5 \text{ or } x^2=25 \text{ or } x = 8\\\\x=\pm\sqrt{-5} \text{ or } x=\pm\sqrt{25} \text{ or } x = 8\\\\x=\pm i\sqrt{5} \text{ or } x=\pm 5 \text{ or } x = 8\\\\[/tex]
where [tex]i = \sqrt{-1}[/tex]
----------------------
The notation [tex]x=\pm i\sqrt{5}[/tex] breaks up into [tex]x=i\sqrt{5} \text{ or } x=-i\sqrt{5}[/tex]. The multiplicity of these two roots is 2 as it's the exponent of the factor [tex](x^2+5)^2[/tex]. Focus on the outermost exponent.
The notation [tex]x = \pm 5[/tex] becomes [tex]x = 5 \text{ or } x = -5[/tex]. The multiplicity of these two roots is 3 since it's the outermost exponent of the factor [tex](x^2-25)^3[/tex]
And finally, the multiplicity of the root x = 8 is 4 because it is the outermost exponent of the factor [tex](x-8)^4[/tex]
A women spent two thirds of her money. She lost two thirds of the remainder and then had $4 left. How much money did she start with?
Answer: She originally had $36
Step-by-step explanation: 4x3 = 12, then multiply that by 3, and you get 36. Because to find the whole you need to multiply each number by three.
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, ∞)

given function of f(x) = 2x - 1 and fg(x) = 10x + 3, find the function of g(x)
Answer:
The function of g(x) = 5x + 2
Step-by-step explanation:
Let us use the composite function to solve the question
∵ f(x) = 2x - 1
∵ f(g(x)) = 10x + 3
→ f(g(x)) means substitute x in f(x) by g(x)
∴ f(g(x)) = 2[g(x)] - 1
→ Equate the two right sides of f(g(x))
∴ 2[g(x)] - 1 = 10x + 3
→ Add 1 to both sides
∴ 2[g(x)] - 1 + 1 = 10x + 3 + 1
∴ 2[g(x)] = 10x + 4
→ Divide each term into both sides by 2
∵ [tex]\frac{2[g(x)]}{2}[/tex] = [tex]\frac{10x}{2}[/tex] + [tex]\frac{4}{2}[/tex]
∴ g(x) = 5x + 2
∴ The function of g(x) = 5x + 2
Can somebody please help me with this math question please
Answer:
Step-by-step explanation:
isosceles triangles are ones that have two equal sides and angles. this would mean that ab is equal to bc. then you substitute the values in for AB=BC, 3x-4=5x-10. you bring the variables to one side and you flip everything which is then 2x=6 and then divide by 2. this would be x=3. then you have to figure out the AB. 3(3)-4=5. then you can always check for BC, 5(3)-10=5. and they are equal! hope i helped!

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
-x + 5y = -4
4x + 3y = 16
Step 2: Rewrite systems
x = 5y + 4
4x + 3y = 16
Step 3: Solve for y
Substitute in x: 4(5y + 4) + 3y = 16Distribute 4: 20y + 16 + 3y = 16Combine like terms: 23y + 16 = 16Subtract 16 on both sides: 23y = 0Divide 23 on both sides: y = 0Step 4: Solve for x
Define: 4x + 3y = 16Substitute in y: 4x + 3(0) = 16Multiply: 4x = 16Isolate x: x = 4And we have our final answer!

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
