Answer:
solve it yourself
Step-by-step explanation:
length of ist part= 30 cm
breadth of ist part = 21 cm
area of ist part = 630 cm
diameter of 2nd part= 21 cm
area of 2nd part = ¼dπ
π= 22/7
= ¼× 21 ×22/7
=3×10.5
= 31.5cm²
total area = ist part +2nd part + 3rd part
=

Albert O'Malley signs a promissory note for $3,500 for 150 days at 9% exact interest. Find the interest he must pay _____ and the total amount due on the due date _____.
Answers
Answer:
He must pay $129.45 and the total amount due is $3,629.45.
Step-by-step explanation:
I (interest) =P (principal) x R (rate) x T (time)
I=3500x.09x150/365
I=129.45
A (amount due) = P (principal) + I (interest)
A= 3500 + 129.45
A= $3629.45

David Smith and his 2 children are going to a zoo.The admission price is:
Adult: £60
Child: £45
David has a family discount card.
Family Discount Card gives
1/4
off adult price
40% off child price
Work out the total price David pays after using his discount card
Answers
Answer:
£101
Step-by-step explanation:
60 divided by 4 = 15
15 x 3 = 45
£45 = adult price
10% of £45 = £4.50
40% of £45 = £18
£45 - £18 = £27
£27 = 1 child ticket
£27 x 2 = £56
£56 = two child tickets
£56 + £45 = £101

Answer:
x=5/3 your answer right answer
Answer:
110
Step-by-step explanation:
The expansion (a + b)³ is
(a + b)³ = a³ + b³ + 3ab(a + b)
Then
(x + [tex]\frac{1}{x}[/tex] )³ with a = x and b = [tex]\frac{1}{x}[/tex]
= x³ + [tex]\frac{1}{x^3}[/tex] + 3x . [tex]\frac{1}{x}[/tex] (x + [tex]\frac{1}{x}[/tex] )
Thus
x³ + [tex]\frac{1}{x^3}[/tex] = (x + [tex]\frac{1}{x}[/tex] )³ - 3(x + [tex]\frac{1}{x}[/tex] )
= 5³ - 3(5)
= 125 - 15
= 110

Find the y intercept of the following line (-2,1) and (1, 2.5)
Answers
Answer:
2
Step-by-step explanation:
(-2 , 1) ; (1, 2.5)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]\frac{2.5-1}{1-[-2]}\\\\= \frac{1.5}{1+2}\\\\=\frac{1.5}{3}\\\\= 0.5[/tex]
m =0.5
y -y1 =m(x -x1)
y - 1 = 0.5(x - [-2])
y - 1 = 0.5(x + 2)
y -1 = 0.5x + 0.5*2
y - 1 =0.5x + 1
y = 0.5x + 1 + 1
y = 0.5x + 2
y-intercept = 2

What is the perimeter of a square if the length of one of the diagonals is 12 cm?
6v2 cm
2412 cm
48 cm
24 cm
Answers
Answer:
Step-by-step explanation:
Use Pythagorean theorem to find the length of the square.
Length of the square = a
a² +a² = diagonal²
2a² = 12²
2a² = 144
a² = 144 ÷ 2
a² = 72
[tex]a =\sqrt{72}\\\\ = \sqrt{2*2*2*3*3}\\\\ = 2*3\sqrt{2}\\\\a = 6\sqrt{2}\\\\\\\\Perimeter= 4a\\\\ = 4*6\sqrt{2}\\\\= 24\sqrt{2} cm[/tex]
