The graph is wrong and can be subject to misinterpretation as the values in the graph don't add up to 100
63+80+70 is equal to 213
Answer:
12 more people adopted a manatee this year.
Step-by-step explanation:
Convert 30% into a decimal. Divide the percentage by 100:
30 / 100 = 0.3
The problem can be solved with the following equation:
0.3(40) = difference
Multiply 0.3 by 40.
0.3 * 40 = 12

Answer:
y = 3/4x + 7
Step-by-step explanation:
8x + 6y = 12
6y = -8x + 12
y = -4/3x + 2
Perpendicular slope: 3/4
y - y1 = m(x - x1)
y + 2 = 3/4(x + 12)
y + 2 = 3/4x + 9
y = 3/4x + 7
Answer:
D) ln (60) = 4.094...
Step-by-step explanation:
Let's solve for x
We'll be careful because it's exponential.
5ex = 300
ex= 300/5
ex= 60
x = e^-1(60)
Let's note that this expression e^-1 is equal to In
x= In (60)
x = 4.0943
So the value of x is equal to 4.0943
Thank you.
Answer:
Their weights are:
Dorris = 5 lbs
Borris = 7 lbs
Morris = 9 lbs
Step-by-step explanation:
Let the weights of the frogs be:
Dorris = d
Borris = b
Morris = m
given:
d + b = 12 - - - (1)
b + m = 16 - - - (2)
d + m = 14 - - - (3)
from (3)
d + m = 14
m = 14 - d - - - (4)
putting the value of m into equation 2:
b + m = 16
b + (14 - d) = 16
b - d + 14 = 16
b - d = 16 - 14
b - d = 2
b = 2 + d - - - - (5)
putting the value of 'b' in equation 5 into equation (1)
d + b = 12 - - - (1)
where: b = 2 + d - - - (5)
∴ d + (2 + d ) = 12
d + d + 2 = 12
2d = 12 - 2
2d = 10
∴ d = 10 ÷ 2 = 5
d = 5
putting the value of 'd' into eqn (5)
b = 2 + d - - - - (5)
where d = 5
b = 2 + 5 = 7
b = 7 lbs
to find 'm', let us use eqn (3)
d + m = 14 - - - (3)
where d = 5
∴ 5 + m = 14
m = 14 - 5 = 9
m = 9 lbs
Therefore their weights are:
Dorris = 5 lbs
Borris = 7 lbs
Morris = 9 lbs
