What is the LCM of 24 and 90?
24,48,72,96,120,144,168,192,216,240,264...360
90,180,270,360
LCM of 24 and 90 is 360
---
hope it helps
Answer:
Step-by-step explanation:
Find the prime factorization of each number
24=2*2*2*3, 90=2*3*3*5
The LCM will be the product of highest occurring primes, in this case
2*2*2*3*3*5=360
So the LCM is 360

Father has 240 oranges in a bag . His neighbor gets 25% of it , his niece gets 1/3 of the reminder and the rest were sold in bags of 5 for 15 . How much money did he earn from the oranges he sold ?
Answer:
he made $360
Step-by-step explanation:
25% of 240
240 × 25 ÷ 100 = 60
his neighbor got 60 orange
remainder is 3/4 or 75 %
75% of 240
240 × 75 ÷ 100 = 180
1/3 of 180
1/3 × 180 = 60
he niece got 60 orange
remainder of orange is 2/3
2/3 = 2/3 × 180 = 120
120 ÷ 5 = 24
he sold 24 bags of orange
24 × 15 = $360
he made $360 from his orange

Which ordered pair is the best estimate for the solution of the system of equations?
y=−34x−2y=x+6
a (−4.5,1.75)
b(−4.25,1.5)
c(−4.5,1.5)
d(−4.75,1.75)
Use the second equation. Replace x with the answer choices and if it equals the y value than that is the answer:
Y = x + 6
-4.5 + 6 = 1.5
The answer would be C. (-4.5,1.5)
Answer:
c(−4.5,1.5) is your answer
write standard form equation of the circle on the graph (easy)
Answer:
The correct answer is D.
Go to your calculator or a graphing website and just graph it.
Answer:
(x-4)²+(y-2)²=9
Step-by-step explanation:
The standard form for a circle is (x-h)²+(y-k)²=r²
(h,k) is the center of a circle and r is the radius
h=4
k=2
r=3
(x-4)²+(y-2)²=3²
(x-4)²+(y-2)²=9

If f(x)=-4x^2-6x-1 and g(x)=-x^2-5x+3, find (f-g)(x).
Answer:
(f-g)(x)=f(x)-g(x)=-4x^2-6x-1 -(-x^2-5x+3,)
=-4x²-6x-1+x²+5x-3
=-4x²+x²-6x+5x-3-1

A cashier checks the price of a hockey stick that is marked $44, because it usually rings up at $80. What is the discount percentage?
Answer:
The discount percentage is 45%.
Step-by-step explanation:
To be able to determine the discount percentage, you can use the following formula:
Discount percentage=(final price-original price/original price)*100
Original price=80
Final price=44
Now, you can replace the values in the formula:
Discount percentage=(44-80/80)*100
Discount percentage=-45%
According to this, the answer is that the discount percentage is 45%.

Damian has a rectangular photo frame. The length of the photo frame is 30 inches, and the width of the frame is 16 1/4 inches. What is the length of the diagonal of this frame in inches?
Answer:
I think it's 34.12 inches
Step-by-step explanation:
Use the Phythagorean Theorem, because bisecting a rectangle using the diagonal will produce 2 triangles. The diagonal represents the hypotenuse of the triangle so to solve for it you'd use the formula c² = a²+b²
