The correct answer is -4/63
Ming could have made it positive because the 2 fractions are negative. However, because theres another negative sign, it is a negative fraction.
Answer:
Step-by-step explanation:
We know that exponential formula of depreciation

where
P is the initial amount
x is the interest rate
A is the amount after t years
we are given
The annual rate of depreciation, x, on a car that was purchased for $9,000
so, P=9000
we can plug value it

we are given
when x=5 , A=4500
so, we can plug it and solve for x





so, interest rate is 13%
now, we can plug x
and we get

Answer:
4.55%
Step-by-step explanation:
To find the percentage of deaths in relation to the number of cases confirmed, we just need to divide the number of deaths by the number of cases confirmed.
So we have that:
Percentage = Deaths / Cases
Percentage = 170 / 3739
Percentage = 0.0455 = 4.55%
The percentage of deaths in relation to the number of cases is 4.55%
Answer:
8 units^2
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
A = 1/2 (7-3) * (4-0)
= 1/2 4*4
= 8
Let us assume the number of vegetarian wraps made = x
Let us assume the number of chicken wraps made = y
Then
x + y = 70
x = 70 - y
And
x + 1.80y = 98.80
Putting the value of x from the first equation in the second equation, we get
x + 1.80y = 98.80
70 - y + 1.80y = 98.80
0.80y = 28.80
y = 36
Putting the value of y in the first equation, we get
x + y = 70
x + 36 = 70
x = 34
From the above deduction, we can conclude that the number of vegetarian warps sold was 34. I hope the answer has come to your desired help.
