You have a slice cut from a perfectly round pizza. The perimeter of your slice is 10 inches. What is the largest area that it can possibly have?
Answer: See explanation
Step-by-step explanation:
A pizza is in the shape of a circle.
Since the perimeter is 10 inches, we have to find the radius. This will be:
2πr = 10
πr = 10/2
πr = 5
3.14r = 5
r = 5/3.14
r = 1.5924
Area = πr²
= 3.14 × 1.5924²
= 7.96 inches
= 8 inches approximately

The coldest temperature ever recorded in New York was -15° on February 9, 1934.The next day the temperature rose 42°. write an expression for the temperature on February 10
Answer:
-15 + 42
Step-by-step explanation:
In order to find the temperature on February 10th, you must add the temperature on the 9th (-15) to the temperature risen the next day (42)
-15 + 42 = 27

A roofer props a ladder against a wall so that the top of the ladder reaches a 20 foot roof that needs repair. If the angle of elevation from the bottom of the ladder to the roof is 46 degrees, what is the length of the ladder to the nearest foot?
Answer:
19.33 ft
Step-by-step explanation:
This analogy has to do with Pythagoras theorem.
We're given our angle of elevation to be 46°, and told that the height of the building to be 20 ft. Using Pythagoras theorem, we know that the given height is opposite to the angle of elevation, and thus, the required distance is adjacent to it.
Sin 46° = opp / hyp
Sin 46° = 20 / hyp
hyp = 20 / sin 46
hyp = 20 / 0.719
hyp = 27.82 ft
We've gotten the length of the ladder, our hypotenuse, to be 27.82. It's tied length we'd then use top find the needed length.
Cos 46° = adj / hyp
Cos 46° = adj / 27.82
adj = 27.82 * Cos 46
adj = 27.82 * 0.695
adj = 19.33 ft
Therefore, the required length is approximately equal to 19.33 ft

4x + 8 is another way of saying
4(x) + 4(2)
-4x - y = 24
Complete the missing value in the solution to the equation.
( _,8)
Answer:
(- 8, 8 )
Step-by-step explanation:
Given ( ?, 8 ) is a solution. To find x substitute y = 8 into the equation, then
- 4x - 8 = 24 ( add 8 to both sides )
- 4x = 32 ( divide both sides by - 4 )
x = - 8
Thus solution is (- 8, 8 )

The equation y = 0.25x describes a proportional relationship between x and y. What is the constant of proportionality?
Answer:
Constant of propotionality is 0.25.
Direct proportionality means that the dependence between the two variable, x and y in this case, is such that the quotient of those two variables is constant.
y/x=0.25 . Quotient of x and y is constant so we can say that x and y are directly proportional.

Two people are standing in a field. One person is flying a kite with a string that is
300 ft long. When the kite is directly above the second person, the cosine value of
the angle made by the string and the ground is :
How far apart are the two people?
The distance between two people or the distance of the adjacent is 150 ft.
What are trigonometric ratios in terms of a right-angle triangle?We know a right-angled triangle has three sides they are -: Hypotenuse,
Opposite and Adjacent.
We can remember SOH CAH TOA which is,
sin = opposite/hypotenuse, cos = adjacent/hypotenuse and
tan = opposite/adjacent.
The distance of the string can be thought of as a hypotenuse which is 300 ft long.
The angle it is making with the hypotenuse is cosine 60° and the distance they are apart can be thought of as an adjacent.
Therefore, cos = adjacent/hypotenuse.
cos60° = adjacent/300.
1/2 = adjacent/300.
adjacent = 300/2.
adjacent = 150 ft.

Answer:
x = 9 3/13 cm
Step-by-step explanation:
area = (length)( width)
20 cm² = (x)(2 1/6 cm)
x = 20 cm²/2 1/6 cm = (20)/(13/6) = (20)(6/13)
x = 9 3/13 cm
Area = 20 cm²
Breadth = 13÷6
Length = x
Area = l × b
20 = l × 13÷6
Therefore: l = 20 × 6 ÷ 13
l = 9 3/13
Therefore x in the figure = 9 3/13

Dr. Howser recently purchased two new fish tanks (Tank A and Tank B) to place in the waiting area of his office. Each fish tank holds exactly 120 gallons of water. Tank A will hold small fish and Tank B will hold large fish. Dr. Howser plans on buying 3 small fish for every 10 gallons of water in Tank A. He plans on buying 6 large fish for every 40 gallons of water in Tank B.
How many total fish is Dr. Howser planning on buying?
What will be the ratio of the number of small fish he buys to the number of large fish that he buys?
Show or explain the steps you used to solve this problem.
Enter your answers and your work or explanation in the box provided.
Answer/Step-by-step explanation:
How many total fish is Dr. Howser planning on buying?
BOTH tanks hold 120 gallons
Tank A :
3 every 10 --> 120/10 ---> 12
So multiply 3 and 12 ----> 36
36 fishes in tank A
Tank B:
6 every 40 -----> 120/40 ----> 3
So multiply 6 by 3 ----> 18
18 fishes are held in tank B
Add them together:
18 + 36 ----> 54
ANSWER : Dr. Howser is planing on purchesing 54 fish all together.
What will be the ratio of the number of small fish he buys to the number of large fish that he buys
Small ---> 36 fish
Large ---> 18 fish
Small : Large ----> 36:18
ANSWER: 36:18
