warm up:Area.how many square units will it take to fill up this rectangle?
Answer:
12
Step-by-step explanation:
here's your solution
=> area of rectangle = length*width
=> area 4*3 = 12.squnit
=> area of square = side^2
=> area = 1.squnit
=> Number of square = area of rectangle/area of square
=> no of square = 12/1
=>. 12
If a circle is cut from a square piece of fabric, how much fabric would be leftover? Use 3.14 for pi. (round to nearest hundredth).
Answer:
0.22 square units
Step-by-step explanation:
Area of the left over fabric = Area of the square piece - Area of the circle
let the side length of the square piece be 1 unit
Area of the square piece = 1 * 1
Area of the square piece = 1 square units
Area of the circle = πd²/4
d is the diameter of the circle = 1 unit (equivalent to the side length of the square)
Area of the circle = π(1)²/4
Area of the circle = 3.14/4
Area of the circle = 0.785square units
Area of the left over fabric = 1- 0785
Area of the left over fabric = 0.215 square units
Hence the amount of fabric that would be leftover is 0.22 square units
Answer:
0.22 square units

A teacher buys 6.25 ounces of a compound for an experiment. The compound costs $4.12 per ounce. The teacher pays with a $50 bill. How much change does the teacher receive?
Answer:
$24.25
Step-by-step explanation:
Given data
We are told that 1 ounce cost $4.12
Hence 6.25 ounces will cost x
cross multiply
x= 6.25*4.12
x=$25.75
This means that the cost of the 6.25 ounces is $25.75
If the teacher pays with a $50 bill, then her change is
=50-25.75
=$24.25
An airplane is 16,000 feet above the ground. It begins to descend at a rate of 140 feet per minute. Write an equation you could use to solve for x, the number of minutes it will take until the plane is 12,600 feet above the ground.
Answer:
16000=140x
It will take 90 minutes to hit 12,600 ft above ground.
Step-by-step explanation:
Just swap out 16000 for 12600. Then solve from there.

that vector is in the 4th quadrent. This means that it will be between 270 and 360 degrees.
setting up directions over the graph (like a compass), the vector would be between East and South
using the diagram below it would most likly be south of east and 350 degrees
The perimeter of a rectangle is represented by the expression 6x + 4. If the width of the rectangle is represented by the expression x – 1, which expression represents the length? 4x + 6 4x – 6 2x + 3 2x + 6
Answer:
2x + 3
Step-by-step explanation:
two sides measure (x-1) which gives 2(x-1) or 2x - 2
subtract 2x - 2 from 6x + 4 to get 4x + 6
4x + 6 represents twice the length so divide it in half to get:
2x + 3
Answer:
The perimeter of a rectangle is represented by the expression 6x + 4. If the width of the rectangle is represented by the expression x – 1, which expression represents the length?
4x + 6 4x – 6 2x + 3 <<<CORRECT 2x + 6

Your goal is to fill a right circular cylinder shaped bucket with water. The bucket has a radius of 6 inches and a height of 12 inches. If you use a right circular cone with a 3 inch radius and a 4 inch height, how many scoops of water will it take to fill the bucket ?
Answer:
36
Step-by-step explanation:
to answer this question :
determine the volume of the cylinder and the cone. Divide the volume of the cylinder by the volume of the coneVolume of a cylinder = nr^2h
n = 22/7
r = radius = 6
h = height = 12
(22/7) x (6^2) x (12) = 1357.71 in^3
Volume of a cone 1/3(nr^2h)
n = 22/7
r = radius = 3
h = height =
4
(1/3) x (22/7) x (3^2) x (4) = 37.71
1357.71 / 37.71 = 36 times
Find the value of x.

Lana bought a sports car for $75,700. If the value of her car decreases 4.3% annually.
When using the exponential DECAY formula, what would be the value of r?
Answer:
The value of r will be 0.043
Step-by-step explanation:
Firstly, we need to write the exponential decay formula
the general form of the formula is;
A = P(1-r)^t
where A is the price after a certain year t
P is the initial value
r is the decay rate
t is the time
From the question, we have that;
r = 4.3%
4.3% in decimal will be 4.3/100 = 0.043

Answer:
EF = 12
arc AG = 62°
Step-by-step explanation:
since ED = 13, EC = 13, so DF = 10/2 = 5
EF² + 13² - 5² = 169 - 25 = 144
EF = √144 = 12
∠AEG = 90° - 28° = 62°
arc AG = 62°

how many ways can 5 friends sit together at the movies in 5 seats?
Answer:
120
Step-by-step explanation:
The number of friends is 5 and there are 5 seats only. So , we can find it out with the help of permutations ,
[tex]\implies ^n P_r = \dfrac{n! }{(n-r)!} [/tex]
⇒ 5! / (5-5)!
⇒ 5! / 1!
⇒ 5!
⇒ 5 × 4 × 3 × 2 × 1
⇒ 120
Hence there are 120 ways by which 5 friends sit together at the movies in 5 seats.5x^2 + 19x + 12=0
