Emma has money into savings accounts. One rate is 8% and the other is 12%. If she has $450 more in the 12% account and the total

dexar [7]

A account 8% B account 12%

A+$450 = B (1)

Ax8% +Bx12%= $220

Ax0.08 + Bx0.12 = 220

Now we replace (1) on B:

Ax0.08 + (A+450)x0.12 = 220

Ax0.08 + Ax0.12 + 54 = 220

Ax0.2 = 166

A= 830.

Now we replace the value of A on equation (1):

830 + 450 = B

B = 1280

Use DEF shown below to answer the question that follows: what is the value of x rounded to the nearest hundredth? Type the numer

Artist 52 [7]

DEF is shown in the attachment.

Answer: x = 36.08

Step-by-step explanation: We can use Law of Sines to determine x, which is written as:

$\frac{x}{sin(F)}=\frac{55}{sin(90)}$

where

F is the angle at vertex F

The angle is calculated knowing that the sum of all internal angles of a triangle is 180°:

F + 49 + 90 = 180

F + 139 = 180

F = 180 - 139

F = 41

Then, Law of Sines will be:

$\frac{x}{sin(41)}=\frac{55}{sin(90)}$

Sin(90) = 1

sin (41) = 0.6560

Substituing and rearraging:

$x=\frac{55}{1}(0.6560)$

x = 36.08

The value of x is 36.08 units
