Step-by-step explanation:
Simon needs 1000 ML of milk
Craig needs 60 G of butter
Answer:
Craig needs 7.5g of butter to make 12 pancakes.
Step-by-step explanation:
To calculate how many times you need to multiply 8 by to make 12, simply divide 12 by 8. This gives you 1.5.
1.5*5 =7.5
So Craig needs 7.5g of butter to make 12 pancakes.

Answer:
mean=12
Step-by-step explanation:
First, order the data like so.
5, 7, 12, 12, 16, 17, 17
Then add them all up.
It is a sum of 86.
Finally divide
86/7=12.2
Since 12.2 movies aren't possible, let's say the mean is 12
Find the radius of the sphere with the given volume. Show all work
Answer:
r = 15
Step-by-step explanation:
Volume of a sphere is given by
V = 4/3 pi r^3
4500 pi = 4/3 pi r^3
Divide each side by pi
4500 = 4/3 r^3
Multiply each side by 3/4
3/4 *4500 = 3/4 *4/3 r^3
3375 = r^3
Take the cube root of each side
(3375)^(1/3) = (r^3)^(1/3)
15 = r
Find the volume of the triangular prism.
_____ cubic centimeters
Explanation:
The hint pretty much gives away the entire answer. You just need to compute [tex]\frac{4 \times 6}{2} \times 8[/tex] and you should get 96 cm^3
The portion [tex]\frac{4 \times 6}{2}[/tex] represents the area of the triangular face (it has base = 6 and height = 4). Recall that base*height/2 is the area of any triangle. The area of the triangle is (4*6)/2 = 24/2 = 12 cm^2.
Once you know the base face area, you multiply that by the depth of the prism which is 8 cm. So we get 12*8 = 96 cm^3

Solve for a. 2.4a + 8 = 27.2
Answer:
Hello! answer: a = 8
Step-by-step explanation:
2.4 × 8 = 19.2
19.2 + 8 = 27.2 therefore a = 8 hope that helps!
Answer:
a = 8
Step-by-step explanation:
2.4a + 8 = 27.2
2.4a + 8 - 8 = 27.2 - 8
2.4a = 19.2
2.4a ÷ 2.4 = 19.2 ÷ 2.4
a = 8
50 point HELP ASAP Question: A rectangle has sides measuring (3x + 8) units and (6x + 5) units.
Part A: What is the expression that represents the area of the rectangle? Show your work to receive full credit.
Part B: What are the degree and classification of the expression obtained in Part A?
Part C: How does Part A demonstrate the closure property for polynomials?
Answer:
see below
Step-by-step explanation:
(3x + 8) units by (6x + 5) units.
A = l*w
= (3x+8)(6x+5)
Distribute
3x*(6x+5) + 8(6x+5)
18x^2 +15x + 48x +40
Combine terms
18x^2+63x+40 units^2
The degree is 2 ( the highest power of x)
This is a trinomial ( it has 3 terms)
Multiplication is closed for polynomial multiplication
We started with polynomials and we ended up with a polynomial.
I DONT UNDERSTAND MATH
Answer:
P = A - 0.2P
Step-by-step explanation:
A = P + Prt
Where,
A = Total amount in an account earning simple interest
P = principal
r = rate
t = time
A = P + Prt
In terms of Payment
P = A - Prt
Holly:
r = 4% = 0.04
t = 5 years
P = A - Prt
= A - (P * 0.04 * 5)
= A - 0.2P
P = A - 0.2P

write 6x-2y=-12 in slope intercept form
Answer:
y = 3x +6
Step-by-step explanation:
6x-2y=-12
Slope intercept form is y = mx+b where m is the slope and b is the y intercept
Subtract 6x from each side
6x-6x-2y=-6x-12
-2y = -6x-12
Divide each side by -2
-2y/-2 = -6x/-2 -12/-2
y = 3x +6
The exchange rate between Japanese yen (¥) and Australian dollars (A$) is ¥100 = A$1.21. Convert ¥4630 into Australian dollars, correct to the nearest cent.
Amount = A$______
Answer:
$46.3 AUD (?)
Step-by-step explanation:
From the information provided, the exchange rate is 0.01 (when rounded to the cent), so we just multiply 4630 by 0.01. This gives us $46.3 AUD. I'm not too sure about my maths, but that's how you would do it. Hope this helps some :)

The ratios that are correct for the triangle are as follows:
sin B = 1 / 2sin C = √3 / 2tan C = √3Trigonometric ratios
The simplest trigonometric ratios are as follows:
sin ∅ = opposite / hypotenusecos ∅ = adjacent / hypotenusetan ∅ = opposite / adjacentAB = √18² - 9²
AB = √324 - 81
AB= √243
AB = 9√3
Therefore, the trigonometric ratio that are correct for the triangle are as follows;

To move toward a personal vision, what smaller steps should you take?
A.
Set smaller, more specific goals.
B.
Participate in many internships.
C.
Change your lifestyle.
D.
Switch your personal vision frequently.
Please select the best answer from the choices provided
A
B
C
D
Explanation:
Setting smaller realistic goals you can achieve will help build momentum on achieving the bigger goals. Think of it like building a house. You can't simply build a house in a single day, week, or even month. It takes a while to lay the foundation, build the frame, etc. Just take it one step at a time and do so at a realistic pace. At the same time, make sure you don't take too small a step or it might seem too nitpicky, and it might take longer than you thought. In short, this is why choice A is the answer.
Choice B is false because you should probably only focus on one internship so you're 100% focused on that only. I suppose you could have perhaps 2 or 3 of them, but it could get tricky to juggle them all. The more tasks you take on, the more stress will come with it and the less time you'll have per job (not to mention less time for everything else). Be honest with yourself as to what you can handle. Personally, I think that one internship should be enough. Ideally it's paid but unfortunately there are unpaid internships that are out there. Go with the best option that will help your career path.
Choice C is false. You don't need to change your lifestyle unless you have bad habits that may be detrimental to your career. If you do need a lifestyle change, then it's probably best to do changes in small steps as the first paragraph mentions.
Choice D is false. You should have a set goal on what you want and stick to it. Yes you can change your mind if you pick something that doesn't make you happy. But you shouldn't change your mind frequently and often, as it would waste time and energy. So this is why planning it out is a good idea.
