The original number could be 57 because 75 > 57. But it could also be 39 or 48.

Explain why the APR does not compare loans for different lengths of time
Usimov [2.4K]

Answer:

APR does not tell you how long your rate is locked for. A 15-year loan may have a lower interest rate, but could have a higher APR, since the loan fees are amortized over a shorter period of time. It is not wise to compare a 30-year loan with a 15-year loan using their respective APRs.

Help please! ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!
solmaris [256]

Answer:

x= 1/2

and y=3

Step-by-step explanation:

Let's solve your system by substitution.

y=10x−2;2x+y=4

Step: Solvey=10x−2for y:

y=10x−2

Step: Substitute10x−2foryin2x+y=4:

2x+y=4

2x+10x−2=4

12x−2=4(Simplify both sides of the equation)

12x−2+2=4+2(Add 2 to both sides)

12x=6

12x

12

=

6

12

(Divide both sides by 12)

x=

2

Step: Substitute

forxiny=10x−2:

y=10x−2

y=10(

)−2

y=3(Simplify both sides of the equation)

Answer:

x= 1 /2

A ball is 4 feet above the ground when Tyrese throws it into the air. Use the quadratic equation 0=−t2+3t+4 to find how much tim
kompoz [17]

Answer:

Step-by-step explanation:

This quadratic models the parabolic motion equation

h=-at^2+v_{i}t+h_{i}

where h is the height of the object after the motion occurs, a is the pull of gravity, v(i) is the initial vertical velocity of the object, and h(i) is the height from which the object was initially launched.  If we are looking for when the ball hits the ground, h = 0, because the height of an object on the ground has no height at all (or 0 height).  To find the time the object was in the air, factor the quadratic and solve for the values of t.

Two factors of 4 that add up to be 3 and multiply to be 4 are -1 and 4.  So t=-1 and t = 4.  Since we know that time can never be negative, then t = 4 seconds.

What is the length of CD? In this diagram, <br> ABC ~ EDC.
Alex777 [14]

Hey there!

Answer:

CD = 3.

Step-by-step explanation:

Since the triangles are similar, we can set up a ratio to determine the other side-lengths:

\frac{12-x}{18} =\frac{x}{6}

Cross multiply:

6(12-x) = 18x

Distribute the '6':

72-6x = 18x

Combine like terms and simplify:

72 = 24x

x = 3

Therefore, the length of CD is 3.
