find area and perimeter of the rectangle with vertices (2,6),(2,-3),(5,-3),and (5,6)
Answer:Find all times on the clock where the angle between the minute and the hour hand (backwards and forwards) equals 26°
Using our clock angle calculator for 5:32, we see that the angle between the hands equals 26°
Using our clock angle calculator for 6:28, we see that the angle between the hands equals 26°
Final Times that form an angle of 26°
Step-by-step explanation:
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%

Size small shirts: 18, 36, 63, 1800
Size large shirts: 4, 8, 14, 200
Step-by-step explanation:
For every 9 small, there is 2 large, therefore if there is 18 small, then there is 4 large because there are two 9s in 18.

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.
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.

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

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 :-)

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
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.

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

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)
