Answer:
£6
Step-by-step explanation:
Let
Plain scones = x
Cheese scones = 3x
Fruits scones = 4(3x)
= 12x
Total price of scones = £96
She sells each scone for the same price.
Total price of scones = Plain scones + Cheese scones + Fruits scones
96 = x + 3x + 12x
96 = 16x
Divide both sides by 16
x = 96/16
= 6
Plain scones = x = £6
Cheese scones = 3x
= 3(6)
= £18
Fruits scones = 4(3x)
= 12x
= 12(6)
= £72
How much does she make from the sale of the plain scones?
She made £6 from the plain scones
Answer:
(C)85.56 cm², 12.4 cm
Step-by-step explanation:
The Area of the screen of the new phone is :
19.68cm² + Area of the current phone screen size
The current phone screen size has dimensions: 6.1 cm and 10.8 cm,
Area of the current phone screen size = 6.1 cm × 10.8cm
Area of the current phone screen size = 65.88 cm²
Hence, The Area of the screen of the new phone is :
19.68cm² + Area of the current phone screen size
= 19.68cm² + 65.88cm²
= 85.56 cm²
The new phone screen must have an area of 85.56cm², which is the product of 6.9 cm and ___
The is calculated as:
85.56cm²/6.9cm
= 12.4cm
Therefore, the new phone screen must have an area of 85.56cm², which is the product of 6.9 cm and 12.4cm
Option C is correct
The solution of are 1 + 2i and 1 – 2i
Solution:
Given, equation is
We have to find the roots of the given quadratic equation
Now, let us use the quadratic formula
--- (1)
Let us determine the nature of roots:
Here in a = 1 ; b = -2 ; c = 5
Since , the roots obtained will be complex conjugates.
Now plug in values in eqn 1, we get,
On solving we get,
we know that square root of -1 is "i" which is a complex number
Hence, the roots of the given quadratic equation are 1 + 2i and 1 – 2i
Answer:
10
Step-by-step explanation:
You do 5C3, which is 5!/((5-3)!3!) -->
