Answer: After 12 days, they receive both again.
Step-by-step explanation:
Since we have given that
Every 4 th day grocery store gets a shipment of pineapples.
Every 6 th day grocery store gets a shipment of bananas.
We need to find the number of days that they will receive both again.
We will do "LCM" of 4 and 6.
L.C.M. of 4 and 6 = 12
So, after 12 days, they receive both again.
For this case we have the following equation:
Subtracting 2 from both sides of the equation we have:
Multiplying by 5 on both sides of the equation:
Thus, the value of "c" is 200.
Answer:
A circle is 360 degrees.
So, 1/10 would be 36 degrees.
So, 3/10 is 36(3)=108 degrees.
108 degrees
Answer:
a) A =( x^2 -4x)/2
b) 16 cm^2
Step-by-step explanation:
Let the base of the triangle be x cm
since it is longer, then the height would be (x-4) cm
Mathematically, the area of a triangle is the product of the base and the height divided by 2
So, we have this as;
A = 1/2(x-4)x
A = x(x-4)/2
A = (x^2 - 4x)/2
A =( x^2 -4x)/2
To find the area, we only need to substitute 8 cm for x
we have this as;
A = (8^2 -4(8))/2
A = (64-32)/2 = 32/2 = 16 cm^2
Step-by-step explanation:
xy = -40 and x + y = 18
=> x(18 - x) = -40
=> 18x - x² = -40
=> x² - 18x - 40 = 0
=> (x - 20)(x + 2) = 0
=> x = 20 or x = -2.
The two numbers 20 and -2.
