36000 candidates appeared in examination.Out of these,45% were girls.If 80% boys and 70% girls were passed,find the passed percent.
Answer:
75.5 % of all candidates passes
Step-by-step explanation:
36000 x .45 = 16200 x .7 = 11,340 girls passed
36000 x .55 = 19800 x .8 = 15,840 boys passed
total of boy and girls who passed = 27,180
27,180 out of 36,000 equals 75.5%
If a large sized pizza of diameter 35 cm is kept on a rectangular base of dimensions 50 cm x 60 cm. Find the area of the base excluding the pizza.
Answer:
2037.89
Step-by-step explanation:
The area of a circle is πr²
This means that the area of the pizza is π*17.5^2
This means that the area =962.11275016187
We then need to find the area of a rectangle which is shown throuhg lenght*width
50*60=3000
We then need to find out the area of the box excluding the pizza so we subtract the area of a pizza
so we have
3000-962.11275016187=2,037.88724983813
Round and get 2037.89

Answer:

2. VX // UY
3. UW ≅ TY ≅ YX
4. YW = [tex]\frac{1}{2}[/tex] TV
5. TX = 2 UW
6. ∠TXV ≅∠WUY
Step-by-step explanation:
The line segment joining the midpoint of two sides of a triangle is parallel to the third side and equal to half its length
In Δ XVT
∵ U is the midpoint of VT
∵ W is the midpoint of VX
∵ XT is the 3rd side of the triangle
→ By using the rule above
∴ UW // TX ⇒ (1)
∴ UW = [tex]\frac{1}{2}[/tex] TX
→ Multiply both sides by 2
∴ 2 UW = TX
∴ TX = 2 UW ⇒ (5)
∵ Y is the midpoint of TX
∴ TY = YX = [tex]\frac{1}{2}[/tex] TX
∵ UW = [tex]\frac{1}{2}[/tex] TX
∴ UW ≅ TY ≅ YX ⇒ (3)
∵ U is the midpoint of VT
∵ Y is the midpoint of XT
∵ VX is the 3rd side of the triangle
→ By using the rule above
∴ UY // VX
∴ VX // UY ⇒ (2)
∴ UY = [tex]\frac{1}{2}[/tex] VX
∵ W is the midpoint of VX
∵ Y is the midpoint of XT
∵ TV is the 3rd side of the triangle
→ By using the rule above
∴ YW // TV
∴ YW = [tex]\frac{1}{2}[/tex] TV ⇒ (4)
∵ 2 Δs UYW and XVT
∵ UY = [tex]\frac{1}{2}[/tex] XV
∵ YW = [tex]\frac{1}{2}[/tex] VT
∵ WU = [tex]\frac{1}{2}[/tex] TX
∴ [tex]\frac{UY}{XV}[/tex] = [tex]\frac{UW}{VT}[/tex] = [tex]\frac{WU}{TX}[/tex] = [tex]\frac{1}{2}[/tex]
→ By using the SSS postulate of similarity
∴ ∠TXV ≅∠WUY ⇒ (6)

PLANTS Of the water lilies in the pond, 43% are yellow. The others are white. A frog randomly jumps onto a lily. Describe the complement of the frog landing on a yellow lily and find its probability.
Answer:
The probability of the frog landing on a complement of yellow lily is 0.57
Step-by-step explanation:
PLANTS Of the water lilies in the pond, 43% are yellow. The others are white.
The complement is [tex]1-p[/tex].
It is given that 43% of plants are lilies it means the probability of a frog randomly jumps onto a lily is: [tex]p=0.43[/tex]
Now the complement is:
[tex]1-p=1-0.43[/tex]
[tex]1-p=0.57[/tex]
Hence, the probability of the frog landing on a complement of yellow lily is 0.57

On a treasure map the actual distance is derectly velated to the scaled distance if 15 miles is represented by 3 centimetres thenvhhow many centimeters to 135 miles
Answer:
27 Centimeters
Step-by-step explanation:
Calculation for how many centimeters on the
treasure map is equivalent to 135 miles
Number of Centimeters to 135 miles=[135 miles/(15 miles÷3 centimetres)]
Number of Centimeters to 135 miles=135 miles/5
Number of Centimeters to 135 miles=27 Centimeters
Therefore the numbers of centimeters on the
treasure map that is equivalent to 135 miles is
27 Centimeters

Answer:
perpendicular
Step-by-step explanation:
L1: find the slope
rise: 2 - (-5) = 7
run: -1 - (-3) = 2
m1 = 7/2
L2:
rise: 2 - 4 = -2
run: 7 - 0 = 7
m2 = -2/7
parallel means same slope m1 = m2
perpendicular means opposite reciprocal (flip and change signs)
7/2 flip and change signs = -2/7, yes thus it is perpendicular

a = -3/5b = 5/9c = -10/3Determining the LEFT-HAND SIDE
[tex]a\times \left(b-c\right)[/tex]
substituting a= -3/5, b= 5/9 and c= -10/3

substituting a= -3/5, b= 5/9 and c= -10/3
[tex]\:a\times \:b-a\times \:c=ab-ac[/tex]
[tex]=-\frac{3}{5}\left(\frac{5}{9}\right)-\left(-\frac{3}{5}\right)\left(-\frac{10}{3}\right)[/tex]

C
m2 = 93°
D
m2B = 87°
E
x = 16
F

Given that,
∠C = (6x-21)° and ∠A = (4x+11)°
To find,
Choose the correct option.
Solution,
For a parallelogram, the opposite angles are equal. ATQ,
(6x-21)° = (4x+11)°
Taking like terms together,
6x-4x = 21 + 11
2x = 32
x = 16
∠C = (6x-21)° = 6(16) -21 = 75°
So, ∠A = 75°
So, ∠A = ∠C = 75°. Hence, the correct option is (B).
