Step-by-step explanation:
the area of a circle is
A = pi × r²
the circumference of a circle is
C = 2 × pi × r
so,
A = pi × r² = 64 in²
r² = 64 / pi
r = sqrt(64 / pi) = 8×sqrt(1/pi) in
the circumference is then
C = 2 × pi × r = 2 × pi × 8×sqrt(1/pi) = 16×pi×sqrt(1/pi) =
= 28.35926161... in

Compare the numerator and denominator of a
fraction that is greater than 100%
Answer:
I don't understand this question...
Step-by-step explanation:
But If you want a fraction greater than 100% than you have to find a percentage that is greater than 100% and convert it into a fraction
Answer: In a fraction, when the numerator is smaller than the denominator, the percent is either between 1% and 100 % or less than 1 %. To make sure that the given fraction is less than 1%, better convert the given fraction into decimal and then convert into percent. In decimal, when the given value is greater than 1, the percent is greater than 100%.
Step-by-step explanation: (1) Divide number by the other number, then (2) multiply by 100 to convert the result to a %. (3) If both numbers are positive, and the resulting percentage is greater than 100%, the numerator is larger than the denominator.
The angles of a triangle are equal to x, x+4 and 20x. What is the measure of the largest angle of the triangle?
Answer:
160°
Step-by-step explanation:
The angle sum theorem tells you the sum of angles in a triangle is 180°. The sum of angles in the given triangle is ...
x + (x +4) + 20x = 180
22x +4 = 180 . . . . . . . . . . collect terms
22x = 176 . . . . . . . . . . subtract 4
x = 8 . . . . . . . . . . . divide by 22
20x = 160 . . . . find the largest angle
The measure of the largest angle is 160°.

AC= 2x-7, BC= x-3, AB= 8. find x
Answer:
x = 12
consider this a straight line:
A B C
-------------------------------------------------
solve for AB:
⇒ AB = AC - BC
⇒ AB = 2x - 7 - ( x - 3 )
⇒ AB = 2x - x - 7 + 3
⇒ AB = x - 4
given AB = 8solve for x:
⇒ x - 4 = 8
⇒ x = 8 + 4
⇒ x = 12
☆solve for AB:
→ AB = AC - BC
→ AB = 2x - 7-(x-3)
→ AB = 2x - x - 7+3
→ AB = x - 4
given, AB = 8
☆solve for x:
→ x - 4 = 8
→ x = 8 + 4
→ x = 12

4.2 Write 1764 as a product of prime factors show your steps
Step-by-step explanation
first you have 1764 so you need to reduce it so you can keep on going through the line so I divided 1764 by 2 and I got 882. 2 is a prime number so I don't have to worry about it anymore. now I reduce 882 and get 2 and 441. 2 is prime so we don't need to worry about it anymore. now since we can't divide 441 by 2 we will use the next number 3. 441 divided by 3 is 147. 3 is prime so we don't need to worry about it anymore. 147 can't be divided by 2 so we will try 3 again and that works so 147 divided by 3 is 49. 3 is prime so we don't have to worry about it anymore. now we have 49 and 49 is a normal multiplication fact so we know that 49 divided by 7 is 7. and seven is prime so now you have have all the prime factors of 1764

PLS HELPP!! Use the Pythagorean theorem to find the hypotenuse for the right triangle below. Be sure to show your work.
Answer:
36.05
Step-by-step explanation:
20²+30²=1300
sqrt*1300=36.05551275464
Answer:
hypotenuse: 36.06 feet
using Pythagoras theorem:
a² + b² = c²
30² + 20² = c²
c² = 900 + 400
c² = 1300
c = √1300
c = 36.0555 feet
c = 36.06 feet

Based on the resultant matrix, what is the number string that corresponds to the decoded message?
The matrix shown represents its elements in rows and columns
Using the assumed matrix, the operation performed on the initial matrix to determine the new resultant matrix is R3 -> 2R2 + R3.
How to determine the matrix operation?The question is incomplete, as the matrix is not shown.
So, I will give a general explanation.
Assume that the matrix is given as:
[tex]\left[\begin{array}{cccc}-4&1&2&4&0&-1&3&1&3&2&4&5\end{array}\right][/tex]
Multiply the elements on the second row (Row 2) by 2.
So, we have:
2R2 = 0 -2 6 2
Add these elements to the third row (Row 3).
So, we have:
2R2 + R3 = 3 0 10 7
Replace the row 3 by the above elements.
i.e.
R3 -> 2R2 + R3.
So, we have:
[tex]\left[\begin{array}{cccc}-4&1&2&4&0&-1&3&1&3&0&10&7\end{array}\right][/tex]
Hence, the operation performed on the initial matrix to determine the new resultant matrix is R3 -> 2R2 + R3.

Answer: I don’t know if you want the area or just y but anyways, y= 9
Step-by-step explanation:
The question requires a scale factor (since both triangles have similar sides (an equal ratio is a good way to think about it) the 10cm side of the large triangle is proportionate to the same side of the smaller triangle.
In other words to get that scale factor (how much one shape is bigger than the other) we need to divide the 10 by 4 (you need to use the same side you can’t do 10/6 because they are completely different sides) 10/4 = 2.5
Now we know the larger triangle is 2.5 times bigger than the smaller triangle. This means the smaller triangle is 2.5 times smaller than the big triangle. So to find the base of the larger triangle we use a similar method we used to find the scale factor (but not divide multiply because when you want to find the bigger you multiply when you want to find scale factor/ smaller you divide) so 6* 2.5= 15 and since y is not the entire base only a part of it, we can do 15(which is the entire length of the big triangle base) - 6 = 9
Therefore y=9

B.
x= 3
O c. y=-8
ОО
D
y= 3x-2
Answer:
y = -8
Step-by-step explanation:
y = 3
is a "flat" horizontal line, which means every point on that line has the same y value no matter what x value we would consider.
any line parallel to that is then also a horizontal line with a constant y value. which y value ? well, the y coordinate of the given point tells us : (-2, -8)
so, the line equation is
y = -8
Answer:
C, y=-8
Step-by-step explanation:
Which equation represents the line that is parallel to y= 3 and passes through (-2,-8)?
y=3 means the y value is always 3, so the line is horizontal and parallel to the y axis.
A, x= -2 this is a vertical line
B. x= 3 this is a vertical line
C, y=-8 this is a horizontal line, where y is always -8 so it is parallel and will pass through -2
D, y= 3x-2 this line will be at an angle

At a state park, the admission fee for 2 buses and 1 van costs $9.50. In June, a group of students on 3 buses and 2 vans enters the state park for a total admission fee of $15.50. In September, a group of students on 7 buses and 4 vans enters the state park for a total admission fee of $34.50.
The cost of a bus is $3.5 while the cost of a van will be $2.50
Systems of equationLet x be the admission fee for a van
Let y be the admission fee for a bus
If the admission fee for 2 buses and 1 van costs $9.50 and 3 buses and 2 vans enters the state park for a total admission fee of $15.50, then the required system of equation will be:
2x + y = 9.50
3x + 2y = 15.59
Using elimination method:
4x + 2y = 19
3x + 2y = 15.59
Subtract
x = 19 - 15.5
x = 3.5
Since 2x + y = 9.50
2(3.5) + y = 9.50
y = 9.50 - 7
y = 2.50
Hence the cost of a bus is $3.5 while the cost of a van will be $2.50

In this problem, the variables are:
Variable h: The TV's height.Variable w: The TV's width.The height of the screen of the tv is one half the width plus 5 inches, hence:
h = 0.5w + 5.
Since the width is of 30 inches:
h = 0.5 x 30 + 5 = 15 + 5 = 20.
The height of the TV is of 20 inches.
