Answer:
18
Step-by-step explanation:
33 - 3 = 30
30 ÷ 2 = 15
15 + 3 = 18
I know i use the product rule but I keep getting the wrong answer
Answer:
dx/dt | (x=3) = 27/2
Explanation:
x*y = 2 ......... (a)
At x = 3, (3)*y = 2 => y = 2/3
Differentiate (a) wrt t,
x.dy/dt + y.dx/dt = 0 ........ (b)
Put x=3, dy/dt=-3 and y=2/3 in the differential equation (b),
3(-3) + (2/3)*dx/dt = 0
dx/dt = (9*3)/2 = 27/2

paul was given 2760$ to buy toys for a group of children.A)what would be the greatest number of toys paul could buy if each toy cost $9?B)how much money would be left after buying the toys? (wright equation)(anser it understandble)
Step-by-step explanation:
Question A-
To find: Greatest number of toys that Paul can buy with $2760
We can simply divide the total money by the toy's price-
total money/toy's price
= 2760 / 9
= 306.6
= 306 (since we cannot buy .6 of a toy we round it off to the previous number)
Question B-
To find: Amount of money left after buying the toys
The remanider of 2760/9 will give us the money left with Paul
= $6

how many acute angles dose a right triangle have?
Answer:
2 acute angles
Step-by-step explanation:
A right triangle HAS to have a right angle, which is 90 degrees. This means the other two angles must add up to:
180-90 = 90 degrees
Acute angles are LESS than 90 degrees. You cannot add two positive integers over 90 to get 90 (obtuse angles), and you can also not have two 90 degree angles since that forms a straight line, therefore meaning the other two angles must be acute.
Answer:
2
Step-by-step explanation:a normal right triangle has 3 angles in total and looking at the bend in each corner only two of them are acute so that makes it 2
Tree A started at 5 feet and grew at a rate of 2 feet per month. Tree B started at 8 feet and grew at a rate of 3 feet per month.
Directions: Write a system of equations. DO NOT SOLVE
Answer:
Step-by-step explanation:
5 + 2x = y
8 + 3x = y
Answer:
Tree A equation: y = 2x + 5. Tree B equation: y = 3x + 8.
Step-by-step explanation:
The rate at which the tree's grow each month is m (y=mx + b) and the starting length of the trees is b (y=mx+b). Once you know those values plug them into the equation.
A farmer needs to water a new potato field. To do so, he builds an irrigation system using 610
plastic pipes and 82 metal pipes. How many pipes does he use?
Answer: Irrigation water can come from groundwater, through springs or wells, surface water, through rivers, lakes, or reservoirs, or even other sources, such as treated wastewater or desalinated water. As a result, it is critical that farmers protect their agricultural water source to minimize the potential for contamination.
Step-by-step explanation:
Answer:
Total pipes = 692 pipes
Step-by-step explanation:
Now we have to,
→ find the amount of pipes he use.
Forming the expression,
→ 610 plastic pipes + 82 metal pipes
Let's solve the problem,
→ 610 plastic pipes + 82 metal pipes
→ 610 + 82
→ 692 pipes
Hence, the farmer used 692 pipes.

Simplify fully please
Answer:
Keep Change Flip. Then, multiply out.
You will get:
x^3 - 9x +2x^2 - 18 / 3x^3 - x^2 - 27x + 9
Now factorise top and bottom to get :
(x+2)(x+3)(x-3) / (3x-1)(x+3)(x-3)
The same bracket at the top and bottom cancels out to give the final answer of:
x+2 / 3x-1
Or
x+2 ÷ 3x-1
Hope this helps!
Use the difference of 2 squares to expand x^2-9 to (x+3)(x-3).
factorizing 3x^2 + 8x -3 gives (3x-1)(x+3). With all these, we can simplify as shown in the picture above

Write the product of 6 x 6 x 6 x z x z in exponential form.
Answer:
[tex]6^3z^2[/tex]
Step-by-step explanation:
1. Count the number of 6's.
There are three 6's, thus making [tex]6^3[/tex].2. Multiply number of 6's by number of z's.
There are two z's, thus making [tex]z^2[/tex]. [tex]6^3 * z^2 = 6^3z^2[/tex].What is the equation of the line that passes through the point (6.-6) and has an undefined slope
Answer:
x=6
Step-by-step explanation:
If a line has an undefined slope, then it has to be a vertical line.
Since the line is vertical, there is only one x value for any given y value. This means we can use the x value in the given coordinate pair to find the equation...

If 16 ounces of bulk rice costs $2.50, how much
would 24 ounces cost?
Answer:
$ 3.75
Step-by-step explanation:
Let the unknown price be x.
Ounces cost
16 ⇒ $ 2.50
24 ⇒ x
Now let us use cross multiplication and find the value of x.
16 × x = 24 × 2.50
16x = 60
Divide both sides by 16.
x = 3.75
Therefore, 24 ounces of bulk rice cost $ 3.75
Hope this helps you :-)

a jeweler sells rings for $35 each plus a flat fee of $5 for shipping for orders up to 10 rings. If customers order more than 10 rings, the cost is $30 per ring and shipping is free. Write a piecewise function to represent the situation.
Answer:
-10=$35r+$5r
+10=$30r
Step-by-step explanation:
This function represents this situation. If someone orders less than ten rings (-10) then they will pay $35 for each ring($35r) plus dollars for each for shipping ($5r)
If someone were to buy more than ten rings (+10) then they will pay $30 for each ring ($30r)

The bull’s-eye on a target has a diameter of 5 inches. The whole target has a diameter of 13.5 inches. What part of the whole target is the bull’s-eye? Enter your answer as a decimal.
Answer:
13.71% or rounded we have 14%
Step-by-step explanation:
We need to find the area so we need to use the formula of Area = piR^2
>> Area of bulls-eye = π(2.5)^2 = 19.63in^2
>> Area of whole target = π(6.75)^2 = 143.13in^2
NOTE: The target values above are halved values of 5 and 13.5
Now, all we have to do is divide the area of the bullseye by the area of the target, so some simple stuff.
19.63/143.13 > 0.13714804 > In a percent we have 13.71% or rounded we have 14%
What number is 85% of 112?
Answer:
So 85 percent of 112
A percentage basically means “out of a hundred”
So 85 percent is 85/100
85/100 is 0.85
KEY word is “of”, we multiply when there’s of
0.85*112= 95.2
95.2 is 85 percent of 112
