Answer:
C = 50.27 m
Step-by-step explanation:
A = πr²
64π = πr²
64 = r²
r = ±8
r = 8
C = 2πr
C = 2π(8)
C = 50.27 m
simplify (5m-2n)². please help me with this.
Answer:
25 m^2 -20mn +4n^2
Step-by-step explanation:
(5m-2n)²
(5m-2n)(5m-2n)
FOIL
first 5m*5m = 25m^2
outer 5m*-2n = -10mn
inner -2n * 5m = -10mn
last -2n * -2n = 4n^2
Add together
25m^2 -10mn -10mn + 4n^2
25 m^2 -20mn +4n^2
What is f(0) given f(x) = 5(x + 2)2 - 10?
Work Shown:
The idea is to replace x with 0 and then use PEMDAS to simplify.
f(x) = 5(x+2)^2 - 10
f(0) = 5(0+2)^2 - 10
f(0) = 5(2)^2 - 10
f(0) = 5(4) - 10
f(0) = 20-10
f(0) = 10
Answer:
10Step-by-step explanation:
[tex]f(x) =5(x+2)^2 -10\\\\f(0) = 5(0+2)^2 -10\\\\= 5(2)^2-10\\\\5(4)-10\\\\20-10\\\\f(0) =10[/tex]
1) A rectangular carpet has a perimeter of 288 inches. The length of the carpet is 96 inches more than the
width. What are the dimensions of the carpet?
Answer:
The width is 24 inches and the length is 120 inches.
Step-by-step explanation:
Let x represent the width of the carpet
The length can be represented by x + 96
Create an equation:
x + x + x + 96 + x + 96 = 288
Add like terms and solve for x:
4x + 192 = 288
4x = 96
x = 24
So, the width is 24 inches. Plug this into x + 96 to find the length:
x + 96
24 + 96
= 120
So, the width is 24 inches and the length is 120 inches.

NEED HELP ASAP ALGEBRA 2
Answer:
a=9
Step-by-step explanation:
We can use the Pythagorean theorem since this is a right triangle
a^2 + b^2 = c^2
a^2 +40 ^2 = 41^2
a^2 + 1600 = 1681
a^2 = 1681-1600
a^2 = 81
Take the square root of each side
sqrt(a^2) = sqrt(81)
a = 9
Answer:
9.
Step-by-step explanation:
Pythagoras Theorem is used in this case:
a² + b² = c²
a² + 40² = 41²
a² + 1600 = 1681
a² = 1681 - 1600
a² = √81
a = 9
9 is the third answer.
A bank charges a 14% interest per annum on a loan. What is the interest rate if charged yearly?
Answer: Per annum means yearly so the interest rate will be 14% as well.
Step-by-step explanation:
If a number line shows tick marks that are not labeled, can you determine the coordinate of a point located at an unlabeled tick mark?
If other tickmarks are labeled, then you could do some detective work (of sorts) to figure out the unlabeled tickmarks.
For example, let's say we had a number line with 1,2,3,... and let's say that 7 was covered up or erased or smudged. So we have 1,2,3,4,5,6,__,8,9. We could then easily determine that 7 must go in that blank spot. This is just one example of course.
Another example could be that if we had a tickmark right in the middle of two whole numbers, say 0 and 1. This unlabeled tickmark would most likely be 1/2 = 0.5 as its at the halfway point between 0 and 1.
Define the terms factor and quantity. Then for the expression −3(4+x)(z−2−y), list all of the factors, and specify which are quantities.
Answer:
A factor are numbers or variables that can be being multiplied to each other to get another number. A factor is a quantity which is used to multiply or divide another quantity to indicate a measurement difference
A quantity is the total number or amount and it is the subject in a given mathematical operation
In the expression, -3×(4 + x)×(z - 2 - y), the factors are;
-3, (4 + x), and (z - 2 - y)
The quantities are the values that are subject to the mathematical operations including;
3, 4, x, z, 2, and y

Calculate the slope.
Answer: 2/3
Step-by-step explanation:
Since the line is going through the origin it slope will use the formula y/x = k where k is the slope. So you can use any point on the number line to determine the slope.
use the point (3,2) using the formula y/x = k divide the y by x.
k = 2/3

Step-by-step explanation:
Simplify:
Apply the rules of the distributed property by multiplying -2 and 3v and -2 and -6: -6v - 12Solve:
Now that we have our simplified form, we can find what v is. First divide each side by -6 to cancel out the -6 next to v.

In the diagram, JOK and MON are straight lines. Angle NOP and Angle NOQ are complimentary angles. Calculate the value of x - y.
Answer:
x - y = 118
Step-by-step explanation:
Since ∠ NOP and ∠ NOQ are complimentary then ∠ POQ = 90°
Since JOK is a straight line then
∠ JOP + ∠ POQ + ∠ QOK = 180 , that is
76 + 90 + y = 180
166 + y = 180 ( subtract 166 from both sides )
y = 14
Since MON is a straight line then
∠ MOK + ∠ KOQ + ∠ QON = 180, that is
x + 14 + 34 = 180
x + 48 = 180 ( subtract 48 from both sides )
x = 132
Thus
x - y = 132 - 14 = 118

Daniel glues two pieces of wood together as part of a model. One piece is 1/2 inch long, and the other is 3/4 inch long. What is the total length of the wood when glued together?
5 points
Answer:
5/4
Step-by-step explanation:
Total length = Sum of the length of the two pieces of wood :
[tex] \frac{1}{2} + \frac{3}{4} \\ lcm = 4 \\ [/tex]
Adjust values according to the lcm
[tex]4 \div 2 \times 1 = 2 \\ 4 \div 4 \times 3 = 3 \\ = \frac{3 + 2}{4} \\ = \frac{5}{4} [/tex]

The temperature at 9:00pm one evening was 40 Fahrenheit. Over the next 4 hours the temperature dropped at n average rate of 3 per hour. What was the temperature at 1:00am?
Answer:
28 degrees Fahrenheit
Step-by-step explanation:
If the temperature at 9:00pm one evening was 40 Fahrenheit. And for the next 3 hour it dropped 3 degrees per hour then it would be
40 - 4 times 3 =
40 - ( 4 times 3 ) =
40 - 12 = 28 degrees Fahrenheit

Lee can make 18 cookies with two cups of flour. How many cookies can he make with three cups of flour?
Answer:
he can make 27 cookies.
Step-by-step explanation:
9×2 is 18
9×3 is 27
Answer:
27 cookies
Step-by-step explanation:
First find how many cookies one cup of flour can make:
18/2
9 cookies per one cup of flour.
Now find how many cookies three cups of flour can make:
9 cookies = 1 cup of flour
? = 3 cups of flour
9 × 3 = 27
Therefore:
3 cups of flour can make 27 cookies.

Answer:
AAS (angle, angle, side)
Step-by-step explanation:
If two angles and the non-included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent. The Angle Side Angle Postulate (ASA) says triangles are congruent if any two angles and their included side are equal in the triangles. An included side is the side between two angles. hope this helps you :)
