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
What number is 85% of 112?
Answers
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
Are the expressions 4a+(5a+3c) and (4a+5a)+3c equivalent? If so, determine what property can be applied to determine that they are equivalent.
Answers
Answer:
Yes, they are equivalent expressions, by the Associative Property
Step-by-step explanation:
Both of these expressions are equal to:
4a + 5a + 3c
(and then, 9a + 3c)
This is all adding so you can add them all up without any of the parentheses. In the question at first the parentheses are grouping together the 5a and 3c, but in the second expression they are wrapped around the 4a and 5a. But in both expressions the order of the three terms does not change. Only the grouping changes. The terms are grouped differently, but the order DOES NOT change. This is Associative property. If the order changes it is Commutative property.

If 16 ounces of bulk rice costs $2.50, how much
would 24 ounces cost?
Answers
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

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?
Answers
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.

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
Answers
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.
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.
Answers
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%

how many acute angles dose a right triangle have?
Answers
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
