Answer: The answer would be 8.2
Answer:
50%
Step-by-step explanation:
The P(even or divisor of 28) = P(even) + P(divisor of 28) - P(even and divisor of 28). The P(even) = 2/4 = 1/2. The P(divisor of 28) = 2/4 = 1/2. The P(even and divisor of 28) = 2/4 = 1/2 as 2,4 are even numbers and divisors of 28.
1/2 + 1/2 - 1/2 = 1/2 = 50%
Answer:
A = 66.5 in²
Step-by-step explanation:
There are a few different equations to find the area of a rhombus. If you are given the measurements of the two diagonals, you can use the following formula:
Area (A) = 
Using this formula, you can multiply the measures of the diagonals and then divide by 2:
area = 
Answer:
Mr mehra's salary is 26250
Step-by-step explanation:
suppose,
Mr mehra's salary is x
so,
He spends in food = 30% of x
=(30/100) . x [x%=x/100]
= 30x/100
=3x/10
He spends in charity =10% of x
=10x/100
=x/10
Money left = 15750
so,
x = 3x/10 + x/10 + 15750
⇒x - 3x/10 - x/10 = 15750
⇒(10x-3x-x) /10 = 15750
⇒6x/10 = 15750
⇒6x=157500
⇒x = 157500/6
⇒x = 26250
∴Mr mehra's salary is 26250
<span>2x^2+8x-7=-2
</span><span>2x^2+8x - 5 = 0
using the formula:- x = [-8 +/- sqrt(8^2 - 4*2*-5) ] / 4
= -2 +/- sqrt 104)/2
= 0.5495 , -4.549
