9 pairs = 18 people
24 - 18 = 6
6 divided by 2 = 3 pairs
3 magnets for 3 pairs is 9 magnets.
Use Pythagorean theorem to solve.
a^2 + b^2 = c^2
6^2 + b ^2 = 14^2
36 + b^2 = 196
Subtract 36 from both sides.
b^2 = 196-36
b^2 = 160
Take the square root of both sides.
b = sqrt 160
As a decimal
b = 12.649
As a simplified radical
b = 4sqrt10
Answer:
b. both functions have a negative slope
Step-by-step explanation:
The given function is

This function is of the form
, where
is the slope and
is the y-intercept.
We can also determine the slope of the function in the table using any two points, say
.
The slope formula is given by,
.
If
, then,

.
We can see that both functions have a negative slope.
The correct answer is B.
Answer:
Mom=30 Daughter=6
Step-by-step explanation:
M=5×D
M+6=3×D
5D=3D-6
2D=6
D=12
M=12×3=36
Now: D=12-6=6
M=36-6=30
Let
x------------><span>Sean vegetable plants
</span>y------------>Liz vegetable plants
z------------>Sejuan vegetable plants
we know that
y=3
z=2
x=3(y+z)--------> 3(3+2)=15
the answer part A) is
Sean has 15 vegetable plants
part B
This is an example of a part-whole problem.----------> true
<span>This is an example of a comparison problem.-------> true
</span>Addition then multiplication can be used to solve the problem.------> true
