The perimeter Perimeter is given by the sum of the sides as follows:
P = z + 5 + z + 5 + z + z
Substituting P=26 and adding like terms,
26 = 10 + 4z
Subtracting -10 to both sides:
26 - 10 = 10 - 10 + 4z
Simplifying:
16 = 4z
Dividing both sides by 4:
16/4 = z
Switching and simplifying:
z = 4
So,
Equation: 26 = 10 + 4z
z = 4

1.5x+ 4.5y=18 solve for x
Answers
Answer: x=12-3y
Step-by-step explanation:
• first we can see this is a linear equation since there are no terms alike.
(Meaning we won’t have just a number as our answer)
• if we are trying to find X then we must do everything else around it.
• first we have inverse operation meaning we have to subtract 4.5y from 18.
This gives us 1.5x = 18 - 4.5y
• now to get X alone we must do inverse operation again, but since it is multiplication this time we must divide.
1.5x = 18 - 4.5y
——- —————
1.5 1.5
• we now can cross off the 1.5 to give us X alone.
X = 18 - 4.5y
—————
1.5
•If we didn’t have like terms we would leave the answer like this but since we do we can simply.
The 18 and 1.5 are alike so this allows us to divide.
18 divided by 1.5 = 12
So this gives us our answer
X = 12 - 4.5y

The value of z in this convex polygon is equal to 66°
What is a polygon?A polygon can be defined as a two-dimensional geometric shape that comprises straight line segments and a finite number of sides.
Note: The number of sides (n) of a pentagon is 5.
In Geometry, the sum of all the interior angles of a polygon with "n" sides is given by this formula:
Interior angle = 180 × (n - 2)
Interior angle = 180 × (5 - 2)
Interior angle = 180 × 3
Interior angle = 540°.
Now, we can determine the value of z as follows:
(180° - 2z) + (180° - z) + 130° + 108° + 140° = 540°
3z - 378° = 540° - 360°
3z = 378° - 180°
3z = 198°
z = 198°/3
z = 66°

Find the probability of pulling a red card out of a standard deck of cards

Answer:
Find the probability of pulling a red card out of a standard deck of cards
Step-by-step explanation:
So, the probability of drawing a red-faced card is 6 out of 52 cards. Thus, the probability of drawing a red face card from a deck of cards is 6/52 = 3/26.
A standard deck of playing card consists 52 cards.
Cards is splitted into 4 suit i.e. Hearts, Spades, Diamond and Clubs.
Each suits consists of 13 cards - the Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, King and Queen.
Hearts & Diamond are red cards and Spades and Clubs are black cards.
Probably = Number of favourable/Possible outcomes/ Total outcomes.
Probability of pulling a red card = 26/ 52 = 0.5

Answers
Answer:
The height of pole is 20√3 m each and distance of pole from the point on road is 60 m and 20 m respectively.
Step-by-step explanation:
Given:
Two poles of equal heights are standing on opposite side of the road which is 80 m wide facing each other. From a point on the road the angle of elevation of poles are 60° and 30° respectively.To Find:
The height of poles and the distance of that point on the road from the pole.Formula used:
tan60° = √3 tan30° = 1/√3Let the height of each pole be H metres.
Also, let's assume that distance of the point from one pole (as shown in figure) be x m.
According to question, we have
tan60° = H/(80-x)
H = (80-x)√3.... (1)
Also, tan30° = H/x
H = x/√3... (2)
Putting value of eq(2) in eq(1), we get
x/√3 = (80-x)√3
x = 3(80-x)
x = 240 - 3x
4x = 240
x = 60 m
Putting value of x in eq(2), we get
H = 60/√3 = 20√3 m
So, the height of pole is 20√3 m each and distance of pole from the point on road is 60 m and 20 m respectively.
Answer:
Height of Pole: 20√3 m
Distance Of Point From Poles: 20m and 60m
Step-by-step explanation:
The attached graph may help you understand my explanation better
The two poles are Ab and CD and are 80m apart
O is the point between them
The angle of elevation from O to A is 60°
The angle of elevation from O to D is 30°
Since the two poles are given to be of equal height,
AB = CD
In ΔAOB using the law of tangents
tan 60° = AB/BO
tan 60° = √3 and AB = x
So we get
√3 = x/BO
Multiplying both sides by BO we get
√3 · BO = x
or BO = x/√3
Looking at ΔCOD
tan 30° = DC/OC
tan 30° = 1/√3
1/√3 = x/OC
OC · ( 1/√3) = x
OC = x ÷ 1/√3
= x · √3/1
OC = √3x
We also know that BO + OC = 80
Plugging this information with values computed gives us
x/√3 + √3x = 80
Multiply by √3 on both sides
(x/√3) · √3 + (√3x) √3 = 80√3
(x/√3) · √3 = x since the √3 terms cancel out
(√3x) √3 = 3x
So we get
(x/√3) · √3 + (√3x) √3 = 80√3
=>
x + 3x = 80√3
4x = 80√3
x = (80√3)/4
x =20√ 3
So the height of each pole = 20√ 3 m ≈ 34.64 m
The distance OC can be found from the previous equation
OC = √3x
=> OC = √3 x 20√3 = 20 x 3 = 60m
Since BO + OC = 80 m
BO = 80 - 60 = 20 m
Answer:
Height of each pole = 20√3 m
The point is located 20 m from one pole and 60 m from the other pole

a*c = -4 [The product of a and c is -4]
b*c = -6 [The product of b and c is -6]
- Rearrange:
1) a*c = -4 to a = (-4/c)
2) b*c = -6 to b = (-6/c)
Now substitute:
a*b = 6
(-4/c)*(-6/c) = 6
(24/c^2) = 6
c^2 = (24/6)
