It would be B I hope it’s right hope this helps
Answer:
D
Step-by-step explanation:
Area of figure
= area of triangle +area of rectangle
Area of triangle
= ½ ×base ×height
= ½(6)(3.5)
= 10.5 ft²
Area of rectangle
= length ×breadth
= 6(4.6)
= 27.6 ft²
Area of figure
= 10.5 +27.6
= 38.1 ft²
Thus, option D is correct.
Answer:
x=1, y=3
Step-by-step explanation:
21x + 7y = 42
Divide this by 7
3x +y = 6
-5x +5y = 10
Divide this by 5
-x+y = 2
Subtract the two equations to eliminate y
3x +y = 6
-(-x+y = 2)
------------------------
3x +y = 6
+x-y = -2
------------------------
4x = 4
Divide by 4
x = 1
Now solve for y
-x+y = 2
-1 +y = 2
Add 1 to each side
y = 2+1
y =3
Answer:
we need at least 17 - card deck
Step-by-step explanation:
From the information given :
We can attempt to solve the question by using pigeonhole principle;
"The pigeonhole principle posits that if more than n pigeons are placed into n pigeonholes some pigeonhole must contain more than one pigeon"
Thus; the minimum number of pigeon; let say at least n pigeons sit on at least one same hole among m hole can be represented by the formula:
m( n - 1 ) + 1
where ;
pigeons are synonymous to card
pigeonholes are synonymous to suits
So; m = 4 ; n = 5
∴ 4 (5 -1 ) + 1 ⇒ 4 (4) + 1
= 16 + 1
= 17
Hence; we need at least 17 - card deck
Answer: 24x2y
