Answer:
1 kilometer = 1000 meters
or
0.001 kilometers = 1 meter
Answer:
B
Step-by-step explanation:
Using the cofunction identity
sin(90 - x)° = cosx°
Here x = 25° , then
cos25° = sin(90 - 25)° = sin65°
For this case, we have the following equation (according to the comments):
First, we factor the quadratic expression in the denominator:
Then, we multiply both sides of the equation by (a-2) (a + 2):
Later, canceling similar terms we have:
We do distributive property on the left side of the equation:
By grouping variables and constant terms we have:
Rewriting we have:
Finally, by clearing "a" we have:
Note: the value of a is a extraneous solution because it makes the denominator of the original equation equal to zero.
Answer:
the student correct, but the value of a= -2 is an extraneous solution
To convert a percent to a fraction you first convert the percent to a decimal than use the same procedure as converting a decimal to a fraction.
Answer:
=165%
=1.65
=165/100
=33/20
=1 13/20
Answer:
Jarrett has 75 comics
Step-by-step explanation:
T = Number of comic books Toby has.
M = Number of comic books Mitch has.
J = Number of comic books Jarrett has.
Toby has 75% as many comic books as Mitch.
T = 3/4 * M
This is because 75% = 75/100 = 3/4
Jarrett has 25% more comic books than Mitch.
J = 5/4 * M
This is because 125% = 125/100 = 5/4
If Toby has 45 comic books, how many comic books does Jarrett have.
1) Substitute T = 45 and Solve for M
T = 3/4 * M
45 = 3/4 * M
45 ÷ 3/4 = M
45 * 4/3 = M
180/3 = M
M = 60
2) Substitute M = 60 and Solve for J
J = 5/4 * M
J = 5/4 * 60
J = 300/4
J = 75
Jarrett has 75 comics
