Mr Hamal had Rs 4,400.He purchased 6 kg of rice at Rs 75 per kg,2packets of oil at Rs 125 per packet and he gave Rs3,300 to his wife. he divided the remaining sum between his son and daughter equally , find the share of each them
Answer: Therefore, his son and daughter got Rs 200.
Step-by-step explanation:
6 kg of rice = 75*6 = Rs 450
2 packets of oil = RS 2*125 = RS 250
now total money he spent = Rs 450 + Rs 250 + Rs Rs 3,300
= Rs 700 + Rs 3,300
= Rs 4000
Money left = Rs 4,400-Rs 4000 = Rs 400
so
400/2 = Rs 200
find the exact value without a calculator cos π\8= cos π/4/2
Answer:
Step-by-step explanation:
1+cos 2a=2cos^2a
cos a=√[(1+cos 2a)/2]
[tex]put~a=\frac{\pi }{8} \\2a=\frac{\pi }{4} \\\\cos\frac{\pi }{8} =\sqrt{\frac{1+cos \frac{\pi }{4} }{2} } \\=\sqrt{\frac{1+\frac{\sqrt{2}}{2} }{2} }\\=\frac{\sqrt{2+\sqrt{2}}}{2}[/tex]

Answer:
-3 adult tickets were sold18 children's tickets were soldStep-by-step explanation:
Using the first equation to write an expression for y, we get ...
y = 15 -x
Substituting that into the second equation gives ...
30x +20(15 -x) = 270
10x +300 = 270 . . . . . . . . . simplify
10x = -30 . . . . . . . . . . . . . subtract 300
x = -3 . . . . . . . . . . . . . . divide by 10
y = 15 -(-3) = 18 . . . . find the corresponding value of y
The number of adult tickets sold is -3; the number of children's tickets sold is 18.
_____
Additional comment
If 15 tickets were sold for 270 the way your problem statement says, then the average ticket price is 270/15 = 18 per ticket. You show the ticket prices to be 20 for children and 30 for adults. That is, the average price is expected to be between 20 and 30. There is something wrong with this problem.
Which Number Is Greatest?
Answer:
24/100 written in decimal form is .24
16% written as a decimal is .16
.24 would be greatest i believe
Step-by-step explanation:
24/100 is in the 100th place so your decimal would be 0.24
16% is also in the 100th place so .16 :)

Day 2: 100 + 90% = 190 bacteria
Day 3: 190 + 90% = 361
Day 4: 361 + 90% = 685.9
Day 5: 685.9 + 90% = 1303.21
Lamar is solving the equation x^2 - 12x = -6 by completing the square. Which

The solution to the equation is x = ± 6√30
Step-by-step explanation:
The expression (2x + a)(4x − 1) is equivalent to 8x2+ bx − 3. Find the value of b.
Answer:
b = 10
Step-by-step explanation:
Expand the left side and compare the coefficients of like terms
(2x + a)(4x - 1) ← expand using FOIL
= 8x² + 4ax - 2x - a = 8x² + x(4a - 2) - a
Compare coefficients of like terms with
8x² + bx - 3
Then a = 3 ( constant term )
b = 4a - 2 ( coefficients of the x- term )
b = 4(3) - 2 = 12 - 2 = 10
Answer:
b = 10
Step-by-step explanation:
We can break those parenthesis like this
[tex](2x + a)(4x - 1) \\ = 2x(4x - 1) + a(4x - 1) \\ = 8{x}^{2} - 2x + 4ax - a[/tex]
And then combine the terms end with x we get
[tex]8 {x}^{2} - 2x + 4ax - a \\ = 8 {x}^{2} + 4ax - 2x - a \\ = 8 {x}^{2} + (4a - 2)x - a[/tex]
Now by comparing 2 expressions, we can see that a is 3, and b = 4a-2 = 12-2 = 10

Answer:
m = 3.625
Step-by-step explanation:
1.2m + 0.65 = 5
~Subtract 0.65 to both sides
1.2m = 4.35
~Divide 1.2 to both sides
m = 3.625

María va de compras a una tienda departamental y adquiere los siguientes productos: 2 pantalones, 4 blusas, 3 pares de calcetas y 2 pares de tenis. El precio de los artículos por unidad es: pantalones $ 600.00, blusas: $350.00, calcetas: $120.00 y tenis: $ 950.00. Si María contaba con $5000.00, calcula cuánto dinero le sobró después de las compras realizadas.
Answer:
Pantalones = $600.00 × 2
$ 1,200.00
Blusas = $350.00 × 4
$ 1,400.00
Calcetas = $120.00 × 3
$ 360.00
Par de tenis = $950.00 × 2
$ 1,900.00
Total a pagar = $4,850.00
$5,000.00
- $4,860.00

A chemical company makes two brands of antifreeze. The first brand is 55% pure antifreeze, and the second brand is 80% pure antifreeze. In order to obtain 180 gallons of a mixture that contains 65% pure antifreeze, how many gallons of each brand of antifreeze must be used?
Step-by-step explanation:
the first brand = (65-55)/(80-55) x 180
= 10/25 × 180
= 72 gallons
the second brand = (80-65)/(80-55)×180
= 15/25 × 180
= 108 gallons
midpoint (12, -9), endpoint (19, 0) the other endpoint is
Answer:
(5, -18)
Brainliest, please!
Step-by-step explanation:
(12, -9)(19, 0)
x distance: 7, y distance: 9
To get the other endpoint, we must apply the opposite.
x distance: -7, y distance: -9
(12, -9)
12 - 7 = 5, -9 - 9 = -18
(5, -18)
