HELP please this is urgent!!!!! (Tangent lines)
Answer:
Perimeter = 32 cm
Step-by-step explanation:
Use the property of tangents drawn to a circle,
"Length of tangents drawn to a circle drawn from a point given outside the circle are equal"
AE = AH = 3 cm
BE = FB = 4 cm
CG = CF = 5 cm
Since, ∠B ≅ ∠D,
Therefore, length of tangents drawn from D will be equal to the length of tangents drawn form B.
Therefore, DG = DH = 4 cm
Now AB = AE + BE
= 3 + 4
= 7 cm
BC = FB + CF
= 4 + 5
= 9 cm
CD = CG + DG
= 5 + 4
= 9 cm
AD = AH + HD
= 3 + 4
= 7 cm
Perimeter of ABCD = AB + BC + CD + AD
= 7 + 9 + 9 + 7
= 32 cm
the difference of 18 and m is equal to the product of m and 7
Answer:
M = 11/2
Step-by-step explanation:
first set up the problem
18-m = m+7
subtract m to both sides
18 -2m = 7
then subtract 18
-2m = -11
divide by negative 2
m = 11/2

If you could help I would really appreciate it, but if not that’s fine. Thank you.
If P(A)=0.54 then what value of P(B) the event A and B are complementary event
Answer:
P(B) = 0.46
Step-by-step explanation:
Probability
The complementary event of a given event A is defined as "not A" or the event that A does not occur.
For example, if A is defined as 'getting a job', then the complement of A is 'not getting a job'.
Event A and its complementary event (call it B) must satisfy:
P(A) + P(B) = 1
If we know P(A)=0.54, then
P(B) = 1 - P(A)
P(B) = 1 - 0.54
P(B) = 0.46

Plz help find each circle measure !!!!!
Answer:
for the first one it is
ED= 26
CF= 13
mED= 136
mHD= 68
mCE= dont know this one but the other ones im positive their right
Step-by-step explanation:
9514 1404 393
Answer:
ED = 26; CF = 13; arc ED = 136°; arc HD = 68°; arc CE = 88°
QU = 8; QR= 16; arc ST = 114°; arc QR = 114°; arc XT = 57°
Step-by-step explanation:
Chords the same distance from the center of the circle are the same length. Chords of the same length intercept arcs of the same angle measure. A radius perpendicular to a chord bisects it and the arc it subtends. The sum of arcs in a circle is 360°. These facts are used to solve the problems here.
__
Circle J
ED = 2×GD = 26
CF = GD = 13
arc ED = arc CD = 136°
arc HD = 1/2 arc CD = 68°
arc CE = 360° - 2×136° = 88°
__
Circle Y
QU = 1/2×ST = 8
QR = ST = 16
arc ST = arc QR = 1/2(360° -34° -98°) = 114°
arc XT = 1/2 arc ST = 57°

Una persona invirtió $25000 en dos cuentas bancarias,una de estas paga el 5% y la otra el 6% de interés simple. Si la persona recibió $1440 en un año ¿que cantidad invirtió en cada cuenta?
Answer:
Esta persona invirtió $ 6000 a la cuenta bancaria que paga 5 % de interés simple anual y $ 19000 a la cuenta bancaria que paga 6 % de interés simple anual.
Step-by-step explanation:
Esta persona invierte [tex]x[/tex] a la cuenta bancaria que paga 5 % de interés simple anual y [tex]25000-x[/tex] a la cuenta bancaria que paga 6 % de interés simple anual. Recibe [tex]1440[/tex] como consecuencia de las ganancias de las dos cuentas, es decir:
[tex]\frac{5\cdot x}{100} + \frac{6\cdot (25000-x)}{100} = 1440[/tex] (1)
Ahora procedemos a resolver la ecuación resultante:
[tex]5\cdot x + 150000-6\cdot x = 144000[/tex]
[tex]150000-144000 = 6\cdot x - 5\cdot x[/tex]
[tex]x = 6000[/tex]
En consecuencia, esta persona invirtió $ 6000 a la cuenta bancaria que paga 5 % de interés simple anual y $ 19000 a la cuenta bancaria que paga 6 % de interés simple anual.

A local venue is selling tickets to a show. They are selling $10 and $15 tickets, each with different seating. If the venue sells 1,000 tickets and collects a total of $12,200 from sales, how many of each type of ticket did they sell? Please explain the work
Answer:
Let $10 tickets be (x)
Let $15 tickets be (y)
Now we know they sold 1000 tickets
And they earned 12,200 from sales
So we can say
X+Y=1000
10x+15y=12,200
We can do substitution
So lets find Y first
Y=1000-x (basically x+y=1000 but solved for Y)
10x+ 15 ( 1000-x)= 12,200
You’d get
10x+15000-15x=12200
Combine and solve for x and you’ll get
x=560
So we know that x is 560
We can just use that to solve for Y
Since X is 560 tickets
And 1000 tickets soled
1000-560=440
440 ($15) tickets
560 ($10) tickets

The points A, B and C have position vectors OA = 6,2, OB = 3,4 and OC = 12, -2 respectively.
Express the vector:
a) BA
b) BC
Answer:(a) BA = (-3,2) (b) BC = (-9,6)
Step-by-step explanation: (a) Vector BA = position vector of B - position vector of A = vector OB - vector OA = (3-6) i + (4-2) j = -3i+2j [i, j are unit vectors along x and y-axis respectively]. Also vector BA=(-3,2). (b) Vector BC = position vector of B - position vector of C = vector OB - vector OC = (3-12) i + (4-(-2)) j = -9i+6j [i, j are unit vectors along x and y-axis respectively]. Also vector BA=(-9,6).

What is the slope of the table?
Write an equation of the line
in slope intercept form that
has a slope of -6 and
passes through the point
(2, -4).
Answer:
y=-6x+8
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m is the slope and b is the y intercept.
We know a point (2,-4) and a slope -6.
We can subtsitute what we know into the equation above, to find what the y intercept is, since the line will pass through the point given.
-4=-6(2)+b
multiply
-4=-12+b
add 12 to both sides
8=b
the y intercept is (0,8)
Now we know what b is, so we know what the full equation is:
y=-6x+8
hope this helps!

17. The sum of four consecutive integers is at most 100. Find the integers.
and solve.
Answer:
23,24,25,26
Step-by-step explanation:
X+(x+1)+(x+2)+(x+3)= 100
4x+6=100
4x=100-6
X=94/4
X=23.5
Ads the sum is said to be AT MOST 100 SO WE WILL ROUND DOWN THE NUMBER
So x=23
X+1=24
X+2=25
X+3=26
Sum=23+24+25+26=98
98<100 so answer is correct
How do I find n in the the permutation equation of nP3 = 990
Answer:
n=11
Step-by-step explanation:
Permutations
The formula to calculate permutations is:
[tex]\displaystyle nPm=\frac{n!}{(n-m)!}[/tex]
We know nP3=990. Substituting:
[tex]\displaystyle nP3=\frac{n!}{(n-3)!}=990[/tex]
Expanding the factorial in the numerator:
[tex]\displaystyle \frac{n(n-1)(n-2)(n-3)!}{(n-3)!}=990[/tex]
Simplifying:
[tex]n(n-1)(n-2)=990[/tex]
This equation can be easily solved by inspection. The product of three consecutive numbers resulting 990. Starting from greatest to smallest, those numbers are 11,10, and 9, thus:
[tex]n(n-1)(n-2)=11*10*9[/tex]
It follows that n=11
